Economics of Good and Evil: The Quest for Economic Meaning from Gilgamesh to Wall Stree... - 1 views

  • Instead of self-confident and self-centered answers, the author humbly asks fundamental questions: What is economics? What is its meaning? Where does this new religion, as it is sometimes called, come from? What are its possibilities and its limitations and borders, if there are any? Why are we so dependent on permanent growing of growth and growth of growing of growth? Where did the idea of progress come from, and where is it leading us? Why are so many economic debates accompanied by obsession and fanaticism?
  • The majority of our political parties act with a narrow materialistic focus when, in their programs, they present the economy and finance first; only then, somewhere at the end, do we find culture as something pasted on or as a libation for a couple of madmen.
  • most of them—consciously or unconsciously—accept and spread the Marxist thesis of the economic base and the spiritual superstructure.

  • He tries to break free of narrow specialization and cross the boundaries between scientific disciplines. Expeditions beyond economics’ borders and its connection to history, philosophy, psychology, and ancient myths are not only refreshing, but necessary for understanding the world of the twenty-first century.
  • Reality is spun from stories, not from material. Zdeněk Neubauer
  • Before it was emancipated as a field, economics lived happily within subsets of philosophy—ethics, for example—miles away from today’s concept of economics as a mathematical-allocative science that views “soft sciences” with a scorn born from positivistic arrogance. But our thousand-year “education” is built on a deeper, broader, and oftentimes more solid base. It is worth knowing about.
  • Outside of our history, we have nothing more.
  • The study of the history of a certain field is not, as is commonly held, a useless display of its blind alleys or a collection of the field’s trials and errors (until we got it right), but history is the fullest possible scope of study of a menu that the given field can offer.
  • History of thought helps us to get rid of the intellectual brainwashing of the age, to see through the intellectual fashion of the day, and to take a couple of steps back.
  • “The separation between the history of a science, its philosophy, and the science itself dissolves into thin air, and so does the separation between science and non-science; differences between the scientific and unscientific are vanishing.”
  • we seek to chart the development of the economic ethos. We ask questions that come before any economic thinking can begin—both philosophically and, to a degree, historically. The area here lies at the very borders of economics—and often beyond. We may refer to this as protoeconomics (to borrow a term from protosociology) or, perhaps more fittingly, metaeconomics (to borrow a term from metaphysics).
  • stories; Adam Smith believed. As he puts it in The Theory of Moral Sentiments, “the desire of being believed, or the desire of persuading, of leading and directing other people, seems to be one of the strongest of all our natural desires.”
  • “The human mind is built to think in terms of narratives … in turn, much of human motivation comes from living through a story of our lives, a story that we tell to ourselves and that creates a framework of our motivation. Life could be just ‘one damn thing after another’ if it weren’t for such stories. The same is true for confidence in a nation, a company, or an institution. Great leaders are foremost creators of stories.”
  • contrary to what our textbooks say, economics is predominantly a normative field. Economics not only describes the world but is frequently about how the world should be (it should be effective, we have an ideal of perfect competition, an ideal of high-GDP growth in low inflation, the effort to achieve high competitiveness …). To this end, we create models, modern parables,
  • I will try to show that mathematics, models, equations, and statistics are just the tip of the iceberg of economics; that the biggest part of the iceberg of economic knowledge consists of everything else; and that disputes in economics are rather a battle of stories and various metanarratives than anything else.
  • That is the reason for this book: to look for economic thought in ancient myths and, vice versa, to look for myths in today’s economics.
  • is a paradox that a field that primarily studies values wants to be value-free. One more paradox is this: A field that believes in the invisible hand of the market wants to be without mysteries.
  • Almost all of the key concepts by which economics operates, both consciously and unconsciously, have a long history, and their roots extend predominantly outside the range of economics, and often completely beyond that of science.
  • The History of Animal Spirits: Dreams Never Sleep
  • In this sense, “the study of economics is too narrow and too fragmentary to lead to valid insight, unless complemented and completed by a study of metaeconomics.”17
  • The more important elements of a culture or field of inquiry such as economics are found in fundamental assumptions that adherents of all the various systems within the epoch unconsciously presuppose. Such assumptions appear so obvious that people do not know what they are assuming, because no other way of putting things has ever occurred to them, as the philosopher Alfred Whitehead notes in Adventures of Ideas.
  • I argue that economic questions were with mankind long before Adam Smith. I argue that the search for values in economics did not start with Adam Smith but culminated with him.
  • We should go beyond economics and study what beliefs are “behind the scenes,” ideas that have often become the dominant yet unspoken assumptions in our theories. Economics is surprisingly full of tautologies that economists are predominantly unaware of. I
  • argue that economics should seek, discover, and talk about its own values, although we have been taught that economics is a value-free science. I argue that none of this is true and that there is more religion, myth, and archetype in economics than there is mathematics.
  • In a way, this is a study of the evolution of both homo economicus and, more importantly, the history of the animal spirits within him. This book tries to study the evolution of the rational as well as the emotional and irrational side of human beings.
  • I argue that his most influential contribution to economics was ethical. His other thoughts had been clearly expressed long before him, whether on specialization, or on the principle of the invisible hand of the market. I try to show that the principle of the invisible hand of the market is much more ancient and developed long before Adam Smith. Traces of it appear even in the Epic of Gilgamesh, Hebrew thought, and in Christianity, and it is expressly stated by Aristophanes and Thomas Aquinas.
  • This is not a book on the thorough history of economic thought. The author aims instead to supplement certain chapters on the history of economic thought with a broader perspective and analysis of the influences that often escape the notice of economists and the wider public.
  • Progress (Naturalness and Civilization)
  • The Economy of Good and Evil
  • from his beginnings, man has been marked as a naturally unnatural creature, who for unique reasons surrounds himself with external possessions. Insatiability, both material and spiritual, are basic human metacharacteristics, which appear as early as the oldest myths and stories.
  • the Hebrews, with linear time, and later the Christians gave us the ideal (or amplified the Hebrew ideal) we now embrace. Then the classical economists secularized progress. How did we come to today’s progression of progress, and growth for growth’s sake?
  • The Need for Greed: The History of Consumption and Labor
  • Metamathematics From where did economics get the concept of numbers as the very foundation of the world?
  • mathematics at the core of economics, or is it just the icing of the cake, the tip of the iceberg of our field’s inquiry?
  • idea that we can manage to utilize our natural egoism, and that this evil is good for something, is an ancient philosophical and mythical concept. We will also look into the development of the ethos of homo economicus, the birth of “economic man.”
  • All of economics is, in the end, economics of good and evil. It is the telling of stories by people of people to people. Even the most sophisticated mathematical model is, de facto, a story, a parable, our effort to (rationally) grasp the world around us.
  • Masters of the Truth
  • Originally, truth was a domain of poems and stories, but today we perceive truth as something much more scientific, mathematical. Where does one go (to shop) for the truth? And who “has the truth” in our epoch?
  • Our animal spirits (something of a counterpart to rationality) are influenced by the archetype of the hero and our concept of what is good.
  • The entire history of ethics has been ruled by an effort to create a formula for the ethical rules of behavior. In the final chapter we will show the tautology of Max Utility, and we will discuss the concept of Max Good.
  • The History of the Invisible Hand of the Market and Homo Economicus
  • We understand “economics” to mean a broader field than just the production, distribution, and consumption of goods and services. We consider economics to be the study of human relations that are sometimes expressible in numbers, a study that deals with tradables, but one that also deals with nontradables (friendship, freedom, efficiency, growth).
  • When we mention economics in this book, we mean the mainstream perception of it, perhaps as best represented by Paul Samuelson.
  • By the term homo economicus, we mean the primary concept of economic anthropology. It comes from the concept of a rational individual, who, led by narrowly egotistical motives, sets out to maximize his benefit.
  • the Epic of Gilgamesh bears witness to the opposite—despite the fact that the first written clay fragments (such as notes and bookkeeping) of our ancestors may have been about business and war, the first written story is mainly about great friendship and adventure.
  • there is no mention of either money or war; for example, not once does anyone in the whole epic sell or purchase something.5 No nation conquers another, and we do not encounter a mention even of the threat of violence.
  • is a story of nature and civilization, of heroism, defiance, and the battle against the gods, and evil; an epic about wisdom, immortality, and also futility.
  • Gilgamesh becomes a hero not only due to his strength, but also due to discoveries and deeds whose importance were in large part economic—direct gaining of construction materials in the case of felling the cedar forest, stopping Enkidu from devastating Uruk’s economy, and discovering new desert routes during his expeditions.
  • Even today, we often consider the domain of humanity (human relations, love, friendship, beauty, art, etc.) to be unproductive;
  • Even today we live in Gilgamesh’s vision that human relations—and therefore humanity itself—are a disturbance to work and efficiency; that people would perform better if they did not “waste” their time and energy on nonproductive things.
  • But it is in friendship where—often by-the-way, as a side product, an externality—ideas and deeds are frequently performed or created that together can altogether change the face of society.19 Friendship can go against an ingrained system in places where an individual does not have the courage to do so himself or herself.
  • As Joseph Stiglitz says, One of the great “tricks” (some say “insights”) of neoclassical economics is to treat labour like any other factor of production. Output is written as a function of inputs—steel, machines, and labour. The mathematics treats labour like any other commodity, lulling one into thinking of labour like an ordinary commodity, such as steel or plastic.
  • Even the earliest cultures were aware of the value of cooperation on the working level—today we call this collegiality, fellowship, or, if you want to use a desecrated term, comradeship. These “lesser relationships” are useful and necessary for society and for companies because work can be done much faster and more effectively if people get along with each other on a human level
  • But true friendship, which becomes one of the central themes of the Epic of Gilgamesh, comes from completely different material than teamwork. Friendship, as C. S. Lewis accurately describes it, is completely uneconomical, unbiological, unnecessary for civilization, and an unneeded relationship
  • Here we have a beautiful example of the power of friendship, one that knows how to transform (or break down) a system and change a person. Enkidu, sent to Gilgamesh as a punishment from the gods, in the end becomes his faithful friend, and together they set out against the gods. Gilgamesh would never have gathered the courage to do something like that on his own—nor would Enkidu.
  • Due to their friendship, Gilgamesh and Enkidu then intend to stand up to the gods themselves and turn a holy tree into mere (construction) material they can handle almost freely, thereby making it a part of the city-construct, part of the building material of civilization, thus “enslaving” that which originally was part of wild nature. This is a beautiful proto-example of the shifting of the borders between the sacred and profane (secular)—and to a certain extent also an early illustration of the idea that nature is there to provide cities and people with raw material and production resources.
  • started with Babylonians—rural nature becomes just a supplier of raw materials, resources (and humans the source of human resources). Nature is not the garden in which humans were created and placed, which they should care for and which they should reside in, but becomes a mere reservoir for natural (re)sources.
  • But labour is unlike any other commodity. The work environment is of no concern for steel; we do not care about steel’s well-being.16
  • Both heroes change—each from opposite poles—into humans. In this context, a psychological dimension to the story may be useful: “Enkidu (…) is Gilgamesh’s alter ego, the dark, animal side of his soul, the complement to his restless heart. When Gilgamesh found Enkidu, he changed from a hated tyrant into the protector of his city. (…)
  • To be human seems to be somewhere in between, or both of these two. We
  • this moment of rebirth from an animal to a human state, the world’s oldest preserved epic implicitly hints at something highly important. Here we see what early cultures considered the beginning of civilization. Here is depicted the difference between people and animals or, better, savages. Here the epic quietly describes birth, the awakening of a conscious, civilized human. We are witnesses to the emancipation of humanity from animals,
  • The entire history of culture is dominated by an effort to become as independent as possible from the whims of nature.39 The more developed a civilization is, the more an individual is protected from nature and natural influences and knows how to create around him a constant or controllable environment to his liking.
  • The price we pay for independence from the whims of nature is dependence on our societies and civilizations. The more sophisticated a given society is as a whole, the less its members are able to survive on their own as individuals, without society.
  • The epic captures one of the greatest leaps in the development of the division of labor. Uruk itself is one of the oldest cities of all, and in the epic it reflects a historic step forward in specialization—in the direction of a new social city arrangement. Because of the city wall, people in the city can devote themselves to things other than worrying about their own safety, and they can continue to specialize more deeply.
  • Human life in the city gains a new dimension and suddenly it seems more natural to take up issues going beyond the life span of an individual. “The city wall symbolizes as well as founds the permanence of the city as an institution which will remain forever and give its inhabitants the certainty of unlimited safety, allowing them to start investing with an outlook reaching far beyond the borders of individual life.
  • The wall around the city of Uruk is, among other things, a symbol of an internal distancing from nature, a symbol of revolts against submission to laws that do not come under the control of man and that man can at most discover and use to his benefit.
  • “The chief thing which the common-sense individual wants is not satisfactions for the wants he had, but more, and better wants.”47
  • If a consumer buys something, theoretically it should rid him of one of his needs—and the aggregate of things they need should be decreased by one item. In reality, though, the aggregate of “I want to have” expands together with the growing aggregate of “I have.”
  • can be said that Enkidu was therefore happy in his natural state, because all of his needs were satiated. On the other hand, with people, it appears that the more a person has, the more developed and richer, the greater the number of his needs (including the unsaturated ones).
  • the Old Testament, this relationship is perceived completely differently. Man (humanity) is created in nature, in a garden. Man was supposed to care for the Garden of Eden and live in harmony with nature and the animals. Soon after creation, man walks naked and is not ashamed, de facto the same as the animals. What is characteristic is that man dresses (the natural state of creation itself is not enough for him), and he (literally and figuratively) covers52 himself—in shame after the fall.53
  • Nature is where one goes to hunt, collect crops, or gather the harvest. It is perceived as the saturator of our needs and nothing more. One goes back to the city to sleep and be “human.” On the contrary, evil resides in nature. Humbaba lives in the cedar forest, which also happens to be the reason to completely eradicate it.
  • Symbolically, then, we can view the entire issue from the standpoint of the epic in the following way: Our nature is insufficient, bad, evil, and good (humane) occurs only after emancipation from nature (from naturalness), through culturing and education. Humanity is considered as being in civilization.
  • The city was frequently (at least in older Jewish writings) a symbol of sin, degeneration, and decadence—nonhumanity. The Hebrews were originally a nomadic nation, one that avoided cities. It is no accident that the first important city57 mentioned in the Bible is proud Babylon,58 which God later turns to dust.
  • is enough, for example, to read the Book of Revelation to see how the vision of paradise developed from the deep Old Testament period, when paradise was a garden. John describes his vision of heaven as a city—paradise is in New Jerusalem, a city where the dimensions of the walls(!) are described in detail, as are the golden streets and gates of pearl.
  • Hebrews later also chose a king (despite the unanimous opposition of God’s prophets) and settled in cities, where they eventually founded the Lord’s Tabernacle and built a temple for Him. The city of Jerusalem later gained an illustrious position in all of religion.
  • this time Christianity (as well as the influence of the Greeks) does not consider human naturalness to be an unambiguous good, and it does not have such an idyllic relationship to nature as the Old Testament prophets.
  • If a tendency toward good is not naturally endowed in people, it must be imputed from above through violence or at least the threat of violence.
  • If we were to look at human naturalness as a good, then collective social actions need a much weaker ruling hand. If people themselves have a natural tendency (propensity) toward good, this role does not have to be supplied by the state, ruler, or, if you wish, Leviathan.
  • How does this affect economics?
  • us return for the last time to the humanization of the wild Enkidu, which is a process we can perceive with a bit of imagination as the first seed of the principle of the market’s invisible hand, and therefore the parallels with one of the central schematics of economic thinking.
  • Sometimes it is better to “harness the devil to the plow” than to fight with him. Instead of summoning up enormous energy in the fight against evil, it is better to use its own energy to reach a goal we desire; setting up a mill on the turbulent river instead of futile efforts to remove the current. This is also how Saint Prokop approached it in one of the oldest Czech legends.
  • Enkidu caused damage and it was impossible to fight against him. But with the help of a trap, trick, this evil was transformed into something that greatly benefited civilization.
  • By culturing and “domesticating” Enkidu, humanity tamed the uncontrollable wild and chaotic evil
  • Enkidu devastated the doings (the external, outside-the-walls) of the city. But he was later harnessed and fights at the side of civilization against nature, naturalness, the natural state of things.
  • A similar motif appears a thousand years after the reversal, which is well known even to noneconomists as the central idea of economics: the invisible hand of the market.
  • A similar story (reforming something animally wild and uncultivated in civilizational achievement) is used by Thomas Aquinas in his teachings. Several centuries later, this idea is fully emancipated in the hands of Bernard Mandeville and his Fable of the Bees: or, Private Vices, Publick Benefits. The economic and political aspects of this idea are—often incorrectly—ascribed to Adam Smith.
  • Here the individual does not try anymore to maximize his goods or profits, but what is important is writing his name in human memory in the form of heroic acts or deeds.
  • immortality, one connected with letters and the cult of the word: A name and especially a written name survives the body.”77
  • After this disappointment, he comes to the edge of the sea, where the innkeeper Siduri lives. As tonic for his sorrow, she offers him the garden of bliss, a sort of hedonistic fortress of carpe diem, where a person comes to terms with his mortality and at least in the course of the end of his life maximizes earthly pleasures, or earthly utility.
  • In the second stage, after finding his friend Enkidu, Gilgamesh abandons the wall and sets out beyond the city to maximalize heroism. “In his (…) search of immortal life, Gilgamesh
  • The hero refuses hedonism in the sense of maximizing terrestrial pleasure and throws himself into things that will exceed his life. In the blink of an eye, the epic turns on its head the entire utility maximization role that mainstream economics has tirelessly tried to sew on people as a part of their nature.81
  • It is simpler to observe the main features of our civilization at a time when the picture was more readable—at a time when our civilization was just being born and was still “half-naked.” In other words, we have tried to dig down to the bedrock of our written civilization;
  • today remember Gilgamesh for his story of heroic friendship with Enkidu, not for his wall, which no longer reaches monumental heights.
  • the eleventh and final tablet, Gilgamesh again loses what he sought. Like Sisyphus, he misses his goal just before the climax
  • is there something from it that is valid today? Have we found in Gilgamesh certain archetypes that are in us to this day?
  • The very existence of questions similar to today’s economic ones can be considered as the first observation. The first written considerations of the people of that time were not so different from those today. In other words: The epic is understandable for us, and we can identify with it.
  • We have also been witnesses to the very beginnings of man’s culturing—a great drama based on a liberation and then a distancing from the natural state.
  • Let us take this as a memento in the direction of our restlessness, our inherited dissatisfaction and the volatility connected to it. Considering that they have lasted five thousand years and to this day we find ourselves in harmony with a certain feeling of futility, perhaps these characteristics are inherent in man.
  • Gilgamesh had a wall built that divided the city from wild nature and created a space for the first human culture. Nevertheless, “not even far-reaching works of civilization could satisfy human desire.”
  • Friendship shows us new, unsuspected adventures, gives us the opportunity to leave the wall and to become neither its builder nor its part—to not be another brick in the wall.
  • with the phenomenon of the creation of the city, we have seen how specialization and the accumulation of wealth was born, how holy nature was transformed into a secular supplier of resources, and also how humans’ individualistic ego was emancipated.
  • to change the system, to break down that which is standing and go on an expedition against the gods (to awaken, from naïveté to awakening) requires friendship.
  • For small acts (hunting together, work in a factory), small love is enough: Camaraderie. For great acts, however, great love is necessary, real love: Friendship. Friendship that eludes the economic understanding of quid pro quo. Friendship gives. One friend gives (fully) for the other. That is friendship for life and death,
  • The thought that humanity comes at the expense of efficiency is just as old as humanity itself—as we have shown, subjects without emotion are the ideal of many tyrants.
  • The epic later crashes this idea through the friendship of Gilgamesh and Enkidu. Friendship—the biologically least essential love, which at first sight appears to be unnecessary
  • less a civilized, city person is dependent on nature, the more he or she is dependent on the rest of society. Like Enkidu, we have exchanged nature for society; harmony with (incalculable) nature for harmony with (incalculable) man.
  • human nature good or evil? To this day these questions are key for economic policy: If we believe that man is evil in his nature, therefore that a person himself is dog eat dog (animal), then the hard hand of a ruler is called for. If we believe that people in and of themselves, in their nature, gravitate toward good, then it is possible to loosen up the reins and live in a society that is more laissez-faire.
  • For a concept of historical progress, for the undeification of heroes, rulers, and nature, mankind had to wait for the Hebrews.
  • Because nature is not undeified, it is beyond consideration to explore it, let alone intervene in it (unless a person was a two-thirds god like Gilgamesh). It
  • They practiced money lending, traded in many assets (…) and especially were engaged in the trading of shares on capital markets, worked in currency exchange and frequently figured as mediators in financial transactions (…), they functioned as bankers and participated in emissions of all possible forms.
  • As regards modern capitalism (as opposed to the ancient and medieval periods) … there are activities in it which are, in certain forms, inherently (and completely necessarily) present—both from an economic and legal standpoint.7
  • As early as the “dark” ages, the Jews commonly used economic tools that were in many ways ahead of their time and that later became key elements of the modern economy:
  • Gilgamesh’s story ends where it began. There is a consistency in this with Greek myths and fables: At the end of the story, no progress occurs, no essential historic change; the story is set in indefinite time, something of a temporal limbo.
  • Jews believe in historical progress, and that progress is in this world.
  • For a nation originally based on nomadism, where did this Jewish business ethos come from? And can the Hebrews truly be considered as the architects of the values that set the direction of our civilization’s economic thought?
  • Hebrew religiosity is therefore strongly connected with this world, not with any abstract world, and those who take pleasure in worldly possessions are not a priori doing anything wrong.
  • PROGRESS: A SECULARIZED RELIGION One of the things the writers of the Old Testament gave to mankind is the idea and notion of progress. The Old Testament stories have their development; they change the history of the Jewish nation and tie in to each other. The Jewish understanding of time is linear—it has a beginning and an end.
  • The observance of God’s Commandments in Judaism leads not to some ethereal other world, but to an abundance of material goods (Genesis 49:25–26, Leviticus 26:3–13, Deuteronomy 28:1–13) (…) There are no accusing fingers pointed at
  • There are no echoes of asceticism nor for the cleansing and spiritual effect of poverty. It is fitting therefore, that the founders of Judaism, the Patriarchs Abraham, Isaac and Jacob, were all wealthy men.12
  • about due to a linear understanding of history. If history has a beginning as well as an end, and they are not the same point, then exploration suddenly makes sense in areas where the fruits are borne only in the next generation.
  • What’s more, economic progress has almost become an assumption of modern functional societies. We expect growth. We take it automatically. Today, if nothing “new” happens, if GDP does not grow (we say it stagnates) for several quarters, we consider it an anomaly.
  • however, the idea of progress itself underwent major changes, and today we perceive it very differently. As opposed to the original spiritual conceptions, today we perceive progress almost exclusively in an economic or scientific-technological sense.
  • Because care for the soul has today been replaced by care for external things,
  • This is why we must constantly grow, because we (deep down and often implicitly) believe that we are headed toward an (economic) paradise on Earth.
  • Only since the period of scientific-technological revolution (and at a time when economics was born as an independent field) is material progress automatically assumed.
  • Jewish thought is the most grounded, most realistic school of thought of all those that have influenced our culture.17 An abstract world of ideas was unknown to the Jews. To this day it is still forbidden to even depict God, people, and animals in symbols, paintings, statues, and drawings.
  • economists have become key figures of great importance in our time (Kacířské eseje o filosofii dějin [Heretical Essays in the Philosophy of History]). They are expected to perform interpretations of reality, give prophetic services (macroeconomic forecasts), reshape reality (mitigate the impacts of the crisis, speed up growth), and, in the long run, provide leadership on the way to the Promised Land—paradise on Earth.
  • REALISM AND ANTIASCETICISM Aside from ideas of progress, the Hebrews brought another very fundamental contribution to our culture: The desacralization of heroes, nature, and rulers.
  • Voltaire writes: “It certain fact is, that in his public laws he [Moses] never so much as once made mention of a life to come, limiting all punishments and all rewards to the present life.”21
  • As opposed to Christianity, the concept of an extraterrestrial paradise or heaven was not developed much in Hebrew thought.19 The paradise of the Israelites—Eden—was originally placed on Earth at a given place in Mesopotamia20 and at a given time,
  • The Hebrews consider the world to be real—not just a shadow reflection of a better world somewhere in the cloud of ideas, something the usual interpretation of history ascribes to Plato. The soul does not struggle against the body and is not its prisoner, as Augustine would write later.
  • The land, the world, the body, and material reality are for Jews the paramount setting for divine history, the pinnacle of creation. This idea is the conditio sine qua non of the development of economics, something of an utterly earthly making,
  • The mythology of the hero-king was strongly developed in that period, which Claire Lalouette summarizes into these basic characteristics: Beauty (a perfect face, on which it is “pleasant to look upon,” but also “beauty,” expressed in the Egyptian word nefer, not only means aesthetics, but contains moral qualities as well),
  • THE HERO AND HIS UNDEIFICATION: THE DREAM NEVER SLEEPS The concept of the hero is more important than it might appear. It may be the remote origin of Keynes’s animal spirits, or the desire to follow a kind of internal archetype that a given individual accepts as his own and that society values.
  • This internal animator of ours, our internal mover, this dream, never sleeps and it influences our behavior—including economic behavior—more than we want to realize.
  • manliness and strength,28 knowledge and intelligence,29 wisdom and understanding, vigilance and performance, fame and renown (fame which overcomes enemies because “a thousand men would not be able to stand firmly in his presence”);30 the hero is a good shepherd (who takes care of his subordinates), is a copper-clad rampart, the shield of the land, and the defender of heroes.
  • Each of us probably has a sort of “hero within”—a kind of internal role-model, template, an example that we (knowingly or not) follow. It is very important what kind of archetype it is, because its role is dominantly irrational and changes depending on time and the given civilization.
  • The oldest was the so-called Trickster—a fraudster; then the culture bearer—Rabbit; the musclebound hero called Redhorn; and finally the most developed form of hero: the Twins.
  • the Egyptian ruler, just as the Sumerian, was partly a god, or the son of a god.31
  • Jacob defrauds his father Isaac and steals his brother Esau’s blessing of the firstborn. Moses murders an Egyptian. King David seduces the wife of his military commander and then has him killed. In his old age, King Solomon turns to pagan idols, and so on.
  • Anthropology knows several archetypes of heroes. The Polish-born American anthropologist Paul Radin examined the myths of North American Indians and, for example, in his most influential book, The Trickster, he describes their four basic archetypes of heroes.
  • The Torah’s heroes (if that term can be used at all) frequently make mistakes and their mistakes are carefully recorded in the Bible—maybe precisely so that none of them could be deified.32
  • We do not have to go far for examples. Noah gets so drunk he becomes a disgrace; Lot lets his own daughters seduce him in a similar state of drunkenness. Abraham lies and (repeatedly) tries to sell his wife as a concubine.
  • the Hebrew heroes correspond most to the Tricksters, the Culture Bearers, and the Twins. The divine muscleman, that dominant symbol we think of when we say hero, is absent here.
  • To a certain extent it can be said that the Hebrews—and later Christianity—added another archetype, the archetype of the heroic Sufferer.35 Job
  • Undeification, however, does not mean a call to pillage or desecration; man was put here to take care of nature (see the story of the Garden of Eden or the symbolism of the naming of the animals). This protection and care of nature is also related to the idea of progress
  • For the heroes who moved our civilization to where it is today, the heroic archetypes of the cunning trickster, culture bearer, and sufferer are rather more appropriate.
  • the Old Testament strongly emphasizes the undeification of nature.37 Nature is God’s creation, which speaks of divinity but is not the domain of moody gods
  • This is very important for democratic capitalism, because the Jewish heroic archetype lays the groundwork much better for the development of the later phenomenon of the hero, which better suits life as we know it today. “The heroes laid down their arms and set about trading to become wealthy.”
  • in an Old Testament context, the pharaoh was a mere man (whom one could disagree with, and who could be resisted!).
  • RULERS ARE MERE MEN In a similar historical context, the Old Testament teachings carried out a similar desacralization of rulers, the so-called bearers of economic policy.
  • Ultimately the entire idea of a political ruler stood against the Lord’s will, which is explicitly presented in the Torah. The Lord unequivocally preferred the judge as the highest form of rule—an

  • Politics lost its character of divine infallibility, and political issues were subject to questioning. Economic policy could become a subject of examination.
  • 44 God first creates with the word and then on individual days He divides light from darkness, water from dry land, day from night, and so forth—and He gives order to things.45 The world is created orderly— it is wisely, reasonably put together. The way of the world is put together at least partially46 decipherably by any other wise and reasonable being who honors rational rules.
  • which for the methodology of science and economics is very important because disorder and chaos are difficult to examine scientifically.43 Faith in some kind of rational and logical order in a system (society, the economy) is a silent assumption of any (economic) examination.
  • THE PRAISE OF ORDER AND WISDOM: MAN AS A PERFECTER OF CREATION The created world has an order of sorts, an order recognizable by us as people,
  • From the very beginning, when God distances Himself from the entire idea, there is an anticipation that there is nothing holy, let alone divine, in politics. Rulers make mistakes, and it is possible to subject them to tough criticism—which frequently occurs indiscriminately through the prophets in the Old Testament.
  • Hebrew culture laid the foundations for the scientific examination of the world.
  • Examining the world is therefore an absolutely legitimate activity, and one that is even requested by God—it is a kind of participation in the Creator’s work.51 Man is called on to understand himself and his surroundings and to use his knowledge for good.
  • I was there when he set heavens in place, when he marked out the horizon on the face of the deep (…) Then I was the craftsman at his side.47
  • There are more urgings to gain wisdom in the Old Testament. “Wisdom calls aloud in the street (…): ‘How long will you simple ones love your simple ways?’”49 Or several chapters later: “Wisdom is supreme; therefore get wisdom. Though it cost all you have, get understanding.”50
  • examination is not forbidden. The fact that order can be grasped by human reason is another unspoken assumption that serves as a cornerstone of any scientific examination.
  • then, my sons, listen to me; blessed are those who keep my ways (…) Blessed is the man who listens to me, watching daily at my doors, waiting at my doorway. For whoever finds me finds life and receives favor from the Lord.
  • the rational examination of nature has its roots, surprisingly, in religion.
  • The Lord brought me forth as the first of his works, before his deeds of old. I was appointed from eternity, from the beginning, before the world began. When there were no oceans, I was given birth, when there were no springs abounding with water, before the mountains were settled in place,
  • The Book of Proverbs emphasizes specifically several times that it was wisdom that was present at the creation of the world. Wisdom personified calls out:
  • The last act, final stroke of the brush of creation, naming of the animals—this act is given to a human, it is not done by God, as one would expect. Man was given the task of completing the act of creation that the Lord began:
  • MAN AS A FINISHER OF CREATION The creation of the world, as it is explained in Jewish teachings, is described in the Book of Genesis. Here God (i) creates, (ii) separates, and (iii) names [my emphasis]:
  • Naming is a symbolic expression. In Jewish culture (and also in our culture to this day), the right to name meant sovereign rights and belonged, for example, to explorers (new places), inventors (new principles), or parents (children)—that is, to those who were there at the genesis, at the origin. This right was handed over by God to mankind.
  • The Naming itself (the capital N is appropriate) traditionally belongs to the crowning act of the Creator and represents a kind of grand finale of creation, the last move of the brush to complete the picture—a signature of the master.
  • Without naming, reality does not exist; it is created together with language. Wittgenstein tightly names this in his tractatus—the limits of our language are the limits of our world.53
  • He invented (fictitiously and completely abstractly!) a framework that was generally accepted and soon “made into” reality. Marx invented similarly; he created the notion of class exploitation. Through his idea, the perception of history and reality was changed for a large part of the world for nearly an entire century.
  • Reality is not a given; it is not passive. Perceiving reality and “facts” requires man’s active participation. It is man who must take the last step, an act (and we
  • How does this relate to economics? Reality itself, our “objective” world, is cocreated, man himself participates in the creation; creation, which is somewhat constantly being re-created.
  • Our scientific models put the finishing touches on reality, because (1) they interpret, (2) they give phenomena a name, (3) they enable us to classify the world and phenomena according to logical forms, and (4) through these models we de facto perceive reality.
  • When man finds a new linguistic framework or analytical model, or stops using the old one, he molds or remolds reality. Models are only in our heads; they are not “in objective reality.” In this sense, Newton invented (not merely discovered!) gravity.
  • A real-ization act on our part represents the creation of a construct, the imputation of sense and order (which is beautifully expressed by the biblical act of naming, or categorization, sorting, ordering).
  • Keynes enters into the history of economic thought from the same intellectual cadence; his greatest contribution to economics was precisely the resurrection of the imperceptible—for example in the form of animal spirits or uncertainty. The economist Piero Mini even ascribes Keynes’s doubting and rebellious approach to his almost Talmudic education.63
  • God connects man with the task of guarding and protecting the Garden of Eden, and thus man actually cocreates the cultural landscape. The Czech philosopher Zdeněk Neubauer also describes this: “Such is reality, and it is so deep that it willingly crystallizes into worlds. Therefore I profess that reality is a creation and not a place of occurrence for objectively given phenomena.”61
  • in this viewpoint it is possible to see how Jewish thought is mystical—it admits the role of the incomprehensible. Therefore, through its groundedness, Jewish thought indulges mystery and defends itself against a mechanistic-causal explanation of the world: “The Jewish way of thinking, according to Veblen, emphasizes the spiritual, the miraculous, the intangible.
  • The Jews believed the exact opposite. The world is created by a good God, and evil appears in it as a result of immoral human acts. Evil, therefore, is induced by man.66 History unwinds according to the morality of human acts.
  • What’s more, history seems to be based on morals; morals seem to be the key determining factors of history. For the Hebrews, history proceeds according to how morally its actors behave.
  • The Sumerians believed in dualism—good and evil deities exist, and the earth of people becomes their passive battlefield.
  • GOOD AND EVIL IN US: A MORAL EXPLANATION OF WELL-BEING We have seen that in the Epic of Gilgamesh, good and evil are not yet addressed systematically on a moral level.
  • This was not about moral-human evil, but rather a kind of natural evil. It is as if good and evil were not touched by morality at all. Evil simply occurred. Period.
  • the epic, good and evil are not envisaged morally—they are not the result of an (a)moral act. Evil was not associated with free moral action or individual will.
  • Hebrew thought, on the other hand, deals intensively with moral good and evil. A moral dimension touches the core of its stories.65
  • discrepancy between savings and investment, and others are convinced of the monetary essence
  • The entire history of the Jewish nation is interpreted and perceived in terms of morality. Morality has become, so to speak, a mover and shaker of Hebrew history.
  • sunspots. The Hebrews came up with the idea that morals were behind good and bad years, behind the economic cycle. But we would be getting ahead of ourselves. Pharaoh’s Dream: Joseph and the First Business Cycle To
  • It is the Pharaoh’s well-known dream of seven fat and seven lean cows, which he told to Joseph, the son of Jacob. Joseph interpreted the dream as a macroeconomic prediction of sorts: Seven years of abundance were to be followed by seven years of poverty, famine, and misery.
  • Self-Contradicting Prophecy Here, let’s make several observations on this: Through taxation74 on the level of one-fifth of a crop75 in good years to save the crop and then open granaries in bad years, the prophecy was de facto prevented (prosperous years were limited and hunger averted—through a predecessor of fiscal stabilization).
  • The Old Testament prophesies therefore were not any deterministic look into the future, but warnings and strategic variations of the possible, which demanded some kind of reaction. If the reaction was adequate, what was prophesied would frequently not occur at all.
  • This principle stands directly against the self-fulfilling prophecy,80 the well-known concept of social science. Certain prophecies become self-fulfilling when expressed (and believed) while others become self-contradicting prophecies when pronounced (and believed).
  • If the threat is anticipated, it is possible to totally or at least partially avoid it. Neither Joseph nor the pharaoh had the power to avoid bounty or crop failure (in this the dream interpretation was true and the appearance of the future mystical), but they avoided the impacts and implications of the prophecy (in this the interpretation of the dream was “false”)—famine did not ultimately occur in Egypt, and this was due to the application of reasonable and very intuitive economic policy.
  • Let us further note that the first “macroeconomic forecast” appears in a dream.
  • back to Torah: Later in this story we will notice that there is no reason offered as to why the cycle occurs (that will come later). Fat years will simply come, and then lean years after them.
  • Moral Explanation of a Business Cycle That is fundamentally different from later Hebrew interpretations, when the Jewish nation tries to offer reasons why the nation fared well or poorly. And those reasons are moral.
  • If you pay attention to these laws and are careful to follow them, then the Lord your God will keep his covenant of love with you, as he swore to your forefathers. He will love you and bless you and increase your numbers.
  • Only in recent times have some currents of economics again become aware of the importance of morals and trust in the form of measuring the quality of institutions, the level of justice, business ethics, corruption, and so forth, and examining their influence on the economy,
  • From today’s perspective, we can state that the moral dimension entirely disappeared from economic thought for a long time, especially due to the implementation of Mandeville’s concept of private vices that contrarily support the public welfare
  • Without being timid, we can say this is the first documented attempt to explain the economic cycle. The economic cycle, the explanation of which is to this day a mystery to economists, is explained morally in the Old Testament.
  • But how do we consolidate these two conflicting interpretations of the economic cycle: Can ethics be responsible for it or not? Can we influence reality around us through our acts?
  • it is not within the scope of this book to answer that question; justice has been done to the question if it manages to sketch out the main contours of possible searches for answers.
  • THE ECONOMICS OF GOOD AND EVIL: DOES GOOD PAY OFF? This is probably the most difficult moral problem we could ask.
  • Kant, the most important modern thinker in the area of ethics, answers on the contrary that if we carry out a “moral” act on the basis of economic calculus (therefore we carry out an hedonistic consideration; see below) in the expectation of later recompense, its morality is lost. Recompense, according to the strict Kant, annuls ethics.
  • Inquiring about the economics of good and evil, however, is not that easy. Where would Kant’s “moral dimension of ethics” go if ethics paid? If we do good for profit, the question of ethics becomes a mere question of rationality.
  • Job’s friends try to show that he must have sinned in some way and, in doing so, deserved God’s punishment. They are absolutely unable to imagine a situation in which Job, as a righteous man, would suffer without (moral) cause. Nevertheless, Job insists that he deserves no punishment because he has committed no offense: “God has wronged me and drawn his net around me.”94
  • But Job remains righteous, even though it does not pay to do so: Though he slay me, yet will I hope in him.95 And till I die, I will not deny my integrity I will maintain my righteousness and never let go of it; my conscience will not reproach me as long as I live.96
  • He remains righteous, even if his only reward is death. What economic advantage could he have from that?
  • morals cannot be considered in the economic dimension of productivity and calculus. The role of the Hebrews was to do good, whether it paid off or not. If good (outgoing) is rewarded by incoming goodness, it is a bonus,99 not a reason to do outgoing good. Good and reward do not correlate to each other.
  • This reasoning takes on a dimension of its own in the Old Testament. Good (incoming) has already happened to us. We must do good (outgoing) out of gratitude for the good (incoming) shown to us in the past.
  • So why do good? After all, suffering is the fate of many biblical figures. The answer can only be: For good itself. Good has the power to be its own reward. In this sense, goodness gets its reward, which may or may not take on a material dimension.
  • the Hebrews offered an interesting compromise between the teachings of the Stoics and Epicureans. We will go into it in detail later, so only briefly
  • constraint. It calls for bounded optimalization (with limits). A kind of symbiosis existed between the legitimate search for one’s own utility (or enjoyment of life) and maintaining rules, which are not negotiable and which are not subject to optimalization.
  • In other words, clear (exogenously given) rules exist that must be observed and cannot be contravened. But within these borders it is absolutely possible, and even recommended, to increase utility.
  • the mining of enjoyment must not come at the expense of exogenously given rules. “Judaism comes therefore to train or educate the unbounded desire … for wealth, so that market activities and patterns of consumption operate within a God-given morality.”102
  • The Epicureans acted with the goal of maximizing utility without regard for rules (rules developed endogenously, from within the system, computed from that which increased utility—this was one of the main trumps of the Epicurean school; they did not need exogenously given norms, and argued that they could “calculate” ethics (what to do) for every given situation from the situation itself).
  • The Stoics could not seek their enjoyment—or, by another name, utility. They could not in any way look back on it, and in no way could they count on it. They could only live according to rules (the greatest weakness of this school was to defend where exogenously the given rules came from and whether they are universal) and take a indifferent stand to the results of their actions.
  • To Love the Law The Jews not only had to observe the law (perhaps the word covenant would be more appropriate), but they were to love it because it was good.
  • Their relationship to the law was not supposed to be one of duty,105 but one of gratitude, love. Hebrews were to do good (outgoing), because goodness (incoming) has already been done to them.
  • This is in stark contrast with today’s legal system, where, naturally, no mention of love or gratefulness exists. But God expects a full internalization of the commandments and their fulfillment with love, not as much duty. By no means was this on the basis of the cost-benefit analyses so widespread in economics today, which determines when it pays to break the law and when not to (calculated on the basis of probability of being caught and the amount of punishment vis-à-vis the possible gain).
  • And now, O Israel, what does the Lord your God ask of you but to fear the Lord your God, to walk in all his ways, to love him, to serve the Lord your God with all your heart and with all your soul, and to observe the Lord’s commands and decrees that I am giving you today for your own good? To the Lord your God belong the heavens, even the highest heavens, the earth and everything in it. Yet the Lord set his affection on your forefathers and loved them….
  • the principle of doing good (outgoing) on the basis of a priori demonstrated good (incoming) was also taken over by the New Testament. Atonement itself is based on an a priori principle; all our acts are preceded by good.
  • The Hebrews, originally a nomadic tribe, preferred to be unrestrained and grew up in constant freedom of motion.
  • Human laws, if they are in conflict with the responsibilities given by God, are subordinate to personal responsibility, and a Jew cannot simply join the majority, even if it is legally allowed. Ethics, the concept of good, is therefore always superior to all local laws, rules, and customs:
  • THE SHACKLES OF THE CITY Owing to the Hebrew’s liberation from Egyptian slavery, freedom and responsibility become the key values of Jewish thought.
  • Laws given by God are binding for Jews, and God is the absolute source of all values,
  • The Hebrew ideal is represented by the paradise of the Garden of Eden, not a city.116 The despised city civilization or the tendency to see in it a sinful and shackling way of life appears in glimpses and allusions in many places in the Old Testament.
  • The nomadic Jewish ethos is frequently derived from Abraham, who left the Chaldean city of Ur on the basis of a command:
  • In addition, they were aware of a thin two-way line between owner and owned. We own material assets, but—to a certain extent—they own us and tie us down. Once we become used to a certain material
  • This way of life had understandably immense economic impacts. First, such a society lived in much more connected relationships, where there was no doubt that everyone mutually depended on each other. Second, their frequent wanderings meant the inability to own more than they could carry; the gathering up of material assets did not have great weight—precisely because the physical weight (mass) of things was tied to one place.
  • One of Moses’s greatest deeds was that he managed to explain to his nation once and for all that it is better to remain hungry and liberated than to be a slave with food “at no cost.”
  • SOCIAL WELFARE: NOT TO ACT IN THE MANNER OF SODOM
  • regulations is developed in the Old Testament, one we hardly find in any other nation of the time. In Hebrew teachings, aside from individual utility, indications of the concept of maximalizing utility societywide appear for the first time as embodied in the Talmudic principle of Kofin al midat S´dom, which can be translated as “one is compelled not to act in the manner of Sodom” and to take care of the weaker members of society.
  • In a jubilee year, debts were to be forgiven,125 and Israelites who fell into slavery due to their indebtedness were to be set free.126
  • Such provisions can be seen as the antimonopoly and social measures of the time. The economic system even then had a clear tendency to converge toward asset concentration, and therefore power as well. It would appear that these provisions were supposed to prevent this process
  • Land at the time could be “sold,” and it was not sale, but rent. The price (rent) of real estate depended on how long there was until a forgiveness year. It was about the awareness that we may work the land, but in the last instance we are merely “aliens and strangers,” who have the land only rented to us for a fixed time. All land and riches came from the Lord.
  • These provisions express a conviction that freedom and inheritance should not be permanently taken away from any Israelite. Last but not least, this system reminds us that no ownership lasts forever and that the fields we plow are not ours but the Lord’s.
  • Glean Another social provision was the right to glean, which in Old Testament times ensured at least basic sustenance for the poorest. Anyone who owned a field had the responsibility not to harvest it to the last grain but to leave the remains in the field for the poor.
  • Tithes and Early Social Net Every Israelite also had the responsibility of levying a tithe from their entire crop. They had to be aware from whom all ownership comes and, by doing so, express their thanks.
  • “Since the community has an obligation to provide food, shelter, and basic economic goods for the needy, it has a moral right and duty to tax its members for this purpose. In line with this duty, it may have to regulate markets, prices and competition, to protect the interests of its weakest members.”135
  • In Judaism, charity is not perceived as a sign of goodness; it is more of a responsibility. Such a society then has the right to regulate its economy in such a way that the responsibility of charity is carried out to its satisfaction.
  • With a number of responsibilities, however, comes the difficulty of getting them into practice. Their fulfillment, then, in cases when it can be done, takes place gradually “in layers.” Charitable activities are classified in the Talmud according to several target groups with various priorities, classified according to, it could be said, rules of subsidiarity.
  • Do not mistreat an alien or oppress him, for you were aliens in Egypt.140 As one can see, aside from widows and orphans, the Old Testament also includes immigrants in its area of social protection.141 The Israelites had to have the same rules apply for them as for themselves—they could not discriminate on the basis of their origin.
  • ABSTRACT MONEY, FORBIDDEN INTEREST, AND OUR DEBT AGE If it appears to us that today’s era is based on money and debt, and our time will be written into history as the “Debt age,” then it will certainly be interesting to follow how this development occurred.
  • Money is a social abstractum. It is a social agreement, an unwritten contract.
  • The first money came in the form of clay tablets from Mesopotamia, on which debts were written. These debts were transferable, so the debts became currency. In the end, “It is no coincidence that in English the root of ‘credit’ is ‘credo,’ the Latin for ‘I believe.’”
  • To a certain extent it could be said that credit, or trust, was the first currency. It can materialize, it can be embodied in coins, but what is certain is that “money is not metal,” even the rarest metal, “it is trust inscribed,”
  • Inseparably, with the original credit (money) goes interest. For the Hebrews, the problem of interest was a social issue: “If you lend money to one of my people among you who is needy, do not be like a moneylender; charge him no interest.”
  • there were also clearly set rules setting how far one could go in setting guarantees and the nonpayment of debts. No one should become indebted to the extent that they could lose the source of their livelihood:
  • In the end, the term “bank” comes from the Italian banci, or the benches that Jewish lenders sat on.157
  • Money is playing not only its classical roles (as a means of exchange, a holder of value, etc.) but also a much greater, stronger role: It can stimulate, drive (or slow down) the whole economy. Money plays a national economic role.
  • In the course of history, however, the role of loans changed, and the rich borrowed especially for investment purposes,
  • Today the position and significance of money and debt has gone so far and reached such a dominant position in society that operating with debts (fiscal policy) or interest or money supply (monetary policy) means that these can, to a certain extent, direct (or at least strongly influence) the whole economy and society.
  • In such a case a ban on interest did not have great ethical significance. Thomas Aquinas, a medieval scholar (1225-1274), also considers similarly; in his time, the strict ban on lending with usurious interest was loosened, possibly due to him.
  • As a form of energy, money can travel in three dimensions, vertically (those who have capital lend to those who do not) and horizontally (speed and freedom in horizontal or geographic motion has become the by-product—or driving force?—of globalization). But money (as opposed to people) can also travel through time.
  • money is something like energy that can travel through time. And it is a very useful energy, but at the same time very dangerous as well. Wherever
  • Aristotle condemned interest162 not only from a moral standpoint, but also for metaphysical reasons. Thomas Aquinas shared the same fear of interest and he too argued that time does not belong to us, and that is why we must not require interest.
  • MONEY AS ENERGY: TIME TRAVEL AND GROSS DEBT PRODUCT (GDP)
  • Due to this characteristic, we can energy-strip the future to the benefit of the present. Debt can transfer energy from the future to the present.163 On the other hand, saving can accumulate energy from the past and send it to the present.
  • labor was not considered degrading in the Old Testament. On the contrary, the subjugation of nature is even a mission from God that originally belonged to man’s very first blessings.
  • LABOR AND REST: THE SABBATH ECONOMY
  • The Jews as well as Aristotle behaved very guardedly toward loans. The issue of interest/usury became one of the first economic debates. Without having an inkling of the future role of economic policy (fiscal and monetary), the ancient Hebrews may have unwittingly felt that they were discovering in interest a very powerful weapon, one that can be a good servant, but (literally) an enslaving master as well.
  • It’s something like a dam. When we build one, we are preventing periods of drought and flooding in the valley; we are limiting nature’s whims and, to a large extent, avoiding its incalculable cycles. Using dams, we can regulate the flow of water to nearly a constant. With it we tame the river (and we can also gain
  • But if we do not regulate the water wisely, it may happen that we would overfill the dam and it would break. For the cities lying in the valley, their end would be worse than if a dam were never there.
  • If man lived in harmony with nature before, now, after the fall, he must fight; nature stands against him and he against it and the animals. From the Garden we have moved unto a (battle)field.
  • Only after man’s fall does labor turn into a curse.168 It could even be said that this is actually the only curse, the curse of the unpleasantness of labor, that the Lord places on Adam.
  • Both Plato and Aristotle consider labor to be necessary for survival, but that only the lower classes should devote themselves to it so that the elites would not have to be bothered with it and so that they could devote themselves to “purely spiritual matters—art, philosophy, and politics.”
  • Work is also not only a source of pleasure but a social standing; It is considered an honor. “Do you see a man skilled in his work? He will serve before kings.”170 None of the surrounding cultures appreciate work as much. The idea of the dignity of labor is unique in the Hebrew tradition.
  • Hebrew thinking is characterized by a strict separation of the sacred from the profane. In life, there are simply areas that are holy, and in which it is not allowed to economize, rationalize, or maximize efficiency.
  • good example is the commandment on the Sabbath. No one at all could work on this day, not even the ones who were subordinate to an observant Jew:
  • the message of the commandment on Saturday communicated that people were not primarily created for labor.
  • Paradoxically, it is precisely this commandment out of all ten that is probably the most violated today.
  • Aristotle even considers labor to be “a corrupted waste of time which only burdens people’s path to true honour.”

  • Saturday was not established to increase efficiency. It was a real ontological break that followed the example of the Lord’s seventh day of creation. Just as the Lord did not rest due to tiredness or to regenerate strength; but because He was done. He was done with His work, so that He could enjoy it, to cherish in His creation.

  • The brain is the most complex organ in the human body
  • It is in these changing connections that memories are stored, habits learned and personalities shaped, by reinforcing certain patterns of brain activity, and losing others.

The new science of death: 'There's something happening in the brain that makes no sense... - 0 views

  • Jimo Borjigin, a professor of neurology at the University of Michigan, had been troubled by the question of what happens to us when we die. She had read about the near-death experiences of certain cardiac-arrest survivors who had undergone extraordinary psychic journeys before being resuscitated. Sometimes, these people reported travelling outside of their bodies towards overwhelming sources of light where they were greeted by dead relatives. Others spoke of coming to a new understanding of their lives, or encountering beings of profound goodness
  • Borjigin didn’t believe the content of those stories was true – she didn’t think the souls of dying people actually travelled to an afterworld – but she suspected something very real was happening in those patients’ brains. In her own laboratory, she had discovered that rats undergo a dramatic storm of many neurotransmitters, including serotonin and dopamine, after their hearts stop and their brains lose oxygen. She wondered if humans’ near-death experiences might spring from a similar phenomenon, and if it was occurring even in people who couldn’t be revived
  • when she looked at the scientific literature, she found little enlightenment. “To die is such an essential part of life,” she told me recently. “But we knew almost nothing about the dying brain.” So she decided to go back and figure out what had happened inside the brains of people who died at the University of Michigan neurointensive care unit.

  • Since the 1960s, advances in resuscitation had helped to revive thousands of people who might otherwise have died. About 10% or 20% of those people brought with them stories of near-death experiences in which they felt their souls or selves departing from their bodies
  • According to several international surveys and studies, one in 10 people claims to have had a near-death experience involving cardiac arrest, or a similar experience in circumstances where they may have come close to death. That’s roughly 800 million souls worldwide who may have dipped a toe in the afterlife.
  • In the 1970s, a small network of cardiologists, psychiatrists, medical sociologists and social psychologists in North America and Europe began investigating whether near-death experiences proved that dying is not the end of being, and that consciousness can exist independently of the brain. The field of near-death studies was born.
  • in 1975, an American medical student named Raymond Moody published a book called Life After Life.
  • Meanwhile, new technologies and techniques were helping doctors revive more and more people who, in earlier periods of history, would have almost certainly been permanently deceased.
  • “We are now at the point where we have both the tools and the means to scientifically answer the age-old question: What happens when we die?” wrote Sam Parnia, an accomplished resuscitation specialist and one of the world’s leading experts on near-death experiences, in 2006. Parnia himself was devising an international study to test whether patients could have conscious awareness even after they were found clinically dead.
  • Borjigin, together with several colleagues, took the first close look at the record of electrical activity in the brain of Patient One after she was taken off life support. What they discovered – in results reported for the first time last year – was almost entirely unexpected, and has the potential to rewrite our understanding of death.
  • “I believe what we found is only the tip of a vast iceberg,” Borjigin told me. “What’s still beneath the surface is a full account of how dying actually takes place. Because there’s something happening in there, in the brain, that makes no sense.”
  • Over the next 30 years, researchers collected thousands of case reports of people who had had near-death experiences
  • Moody was their most important spokesman; he eventually claimed to have had multiple past lives and built a “psychomanteum” in rural Alabama where people could attempt to summon the spirits of the dead by gazing into a dimly lit mirror.
  • near-death studies was already splitting into several schools of belief, whose tensions continue to this day. One influential camp was made up of spiritualists, some of them evangelical Christians, who were convinced that near-death experiences were genuine sojourns in the land of the dead and divine
  • It is no longer unheard of for people to be revived even six hours after being declared clinically dead. In 2011, Japanese doctors reported the case of a young woman who was found in a forest one morning after an overdose stopped her heart the previous night; using advanced technology to circulate blood and oxygen through her body, the doctors were able to revive her more than six hours later, and she was able to walk out of the hospital after three weeks of care
  • The second, and largest, faction of near-death researchers were the parapsychologists, those interested in phenomena that seemed to undermine the scientific orthodoxy that the mind could not exist independently of the brain. These researchers, who were by and large trained scientists following well established research methods, tended to believe that near-death experiences offered evidence that consciousness could persist after the death of the individua
  • Their aim was to find ways to test their theories of consciousness empirically, and to turn near-death studies into a legitimate scientific endeavour.
  • Finally, there emerged the smallest contingent of near-death researchers, who could be labelled the physicalists. These were scientists, many of whom studied the brain, who were committed to a strictly biological account of near-death experiences. Like dreams, the physicalists argued, near-death experiences might reveal psychological truths, but they did so through hallucinatory fictions that emerged from the workings of the body and the brain.
  • Between 1975, when Moody published Life After Life, and 1984, only 17 articles in the PubMed database of scientific publications mentioned near-death experiences. In the following decade, there were 62. In the most recent 10-year span, there were 221.
  • Today, there is a widespread sense throughout the community of near-death researchers that we are on the verge of great discoveries
  • “We really are in a crucial moment where we have to disentangle consciousness from responsiveness, and maybe question every state that we consider unconscious,”
  • “I think in 50 or 100 years time we will have discovered the entity that is consciousness,” he told me. “It will be taken for granted that it wasn’t produced by the brain, and it doesn’t die when you die.”
  • it is in large part because of a revolution in our ability to resuscitate people who have suffered cardiac arrest
  • In his book, Moody distilled the reports of 150 people who had had intense, life-altering experiences in the moments surrounding a cardiac arrest. Although the reports varied, he found that they often shared one or more common features or themes. The narrative arc of the most detailed of those reports – departing the body and travelling through a long tunnel, having an out-of-body experience, encountering spirits and a being of light, one’s whole life flashing before one’s eyes, and returning to the body from some outer limit – became so canonical that the art critic Robert Hughes could refer to it years later as “the familiar kitsch of near-death experience”.
  • Loss of oxygen to the brain and other organs generally follows within seconds or minutes, although the complete cessation of activity in the heart and brain – which is often called “flatlining” or, in the case of the latter, “brain death” – may not occur for many minutes or even hours.
  • That began to change in 1960, when the combination of mouth-to-mouth ventilation, chest compressions and external defibrillation known as cardiopulmonary resuscitation, or CPR, was formalised. Shortly thereafter, a massive campaign was launched to educate clinicians and the public on CPR’s basic techniques, and soon people were being revived in previously unthinkable, if still modest, numbers.
  • scientists learned that, even in its acute final stages, death is not a point, but a process. After cardiac arrest, blood and oxygen stop circulating through the body, cells begin to break down, and normal electrical activity in the brain gets disrupted. But the organs don’t fail irreversibly right away, and the brain doesn’t necessarily cease functioning altogether. There is often still the possibility of a return to life. In some cases, cell death can be stopped or significantly slowed, the heart can be restarted, and brain function can be restored. In other words, the process of death can be reversed.
  • In a medical setting, “clinical death” is said to occur at the moment the heart stops pumping blood, and the pulse stops. This is widely known as cardiac arrest
  • In 2019, a British woman named Audrey Schoeman who was caught in a snowstorm spent six hours in cardiac arrest before doctors brought her back to life with no evident brain damage.
  • That is a key tenet of the parapsychologists’ arguments: if there is consciousness without brain activity, then consciousness must dwell somewhere beyond the brain
  • Some of the parapsychologists speculate that it is a “non-local” force that pervades the universe, like electromagnetism. This force is received by the brain, but is not generated by it, the way a television receives a broadcast.
  • In order for this argument to hold, something else has to be true: near-death experiences have to happen during death, after the brain shuts down
  • To prove this, parapsychologists point to a number of rare but astounding cases known as “veridical” near-death experiences, in which patients seem to report details from the operating room that they might have known only if they had conscious awareness during the time that they were clinically dead.
  • At the very least, Parnia and his colleagues have written, such phenomena are “inexplicable through current neuroscientific models”. Unfortunately for the parapsychologists, however, none of the reports of post-death awareness holds up to strict scientific scrutiny. “There are many claims of this kind, but in my long decades of research into out-of-body and near-death experiences I never met any convincing evidence that this is true,”
  • In other cases, there’s not enough evidence to prove that the experiences reported by cardiac arrest survivors happened when their brains were shut down, as opposed to in the period before or after they supposedly “flatlined”. “So far, there is no sufficiently rigorous, convincing empirical evidence that people can observe their surroundings during a near-death experience,”
  • The parapsychologists tend to push back by arguing that even if each of the cases of veridical near-death experiences leaves room for scientific doubt, surely the accumulation of dozens of these reports must count for something. But that argument can be turned on its head: if there are so many genuine instances of consciousness surviving death, then why should it have so far proven impossible to catch one empirically?
  • The spiritualists and parapsychologists are right to insist that something deeply weird is happening to people when they die, but they are wrong to assume it is happening in the next life rather than this one. At least, that is the implication of what Jimo Borjigin found when she investigated the case of Patient One.
  • Given the levels of activity and connectivity in particular regions of her dying brain, Borjigin believes it’s likely that Patient One had a profound near-death experience with many of its major features: out-of-body sensations, visions of light, feelings of joy or serenity, and moral re-evaluations of one’s life. Of course,
  • “As she died, Patient One’s brain was functioning in a kind of hyperdrive,” Borjigin told me. For about two minutes after her oxygen was cut off, there was an intense synchronisation of her brain waves, a state associated with many cognitive functions, including heightened attention and memory. The synchronisation dampened for about 18 seconds, then intensified again for more than four minutes. It faded for a minute, then came back for a third time.
  • n those same periods of dying, different parts of Patient One’s brain were suddenly in close communication with each other. The most intense connections started immediately after her oxygen stopped, and lasted for nearly four minutes. There was another burst of connectivity more than five minutes and 20 seconds after she was taken off life support. In particular, areas of her brain associated with processing conscious experience – areas that are active when we move through the waking world, and when we have vivid dreams – were communicating with those involved in memory formation. So were parts of the brain associated with empathy. Even as she slipped irre
  • something that looked astonishingly like life was taking place over several minutes in Patient One’s brain.
  • Although a few earlier instances of brain waves had been reported in dying human brains, nothing as detailed and complex as what occurred in Patient One had ever been detected.
  • In the moments after Patient One was taken off oxygen, there was a surge of activity in her dying brain. Areas that had been nearly silent while she was on life support suddenly thrummed with high-frequency electrical signals called gamma waves. In particular, the parts of the brain that scientists consider a “hot zone” for consciousness became dramatically alive. In one section, the signals remained detectable for more than six minutes. In another, they were 11 to 12 times higher than they had been before Patient One’s ventilator was removed.
  • “The brain, contrary to everybody’s belief, is actually super active during cardiac arrest,” Borjigin said. Death may be far more alive than we ever thought possible.
  • “The brain is so resilient, the heart is so resilient, that it takes years of abuse to kill them,” she pointed out. “Why then, without oxygen, can a perfectly healthy person die within 30 minutes, irreversibly?”
  • Evidence is already emerging that even total brain death may someday be reversible. In 2019, scientists at Yale University harvested the brains of pigs that had been decapitated in a commercial slaughterhouse four hours earlier. Then they perfused the brains for six hours with a special cocktail of drugs and synthetic blood. Astoundingly, some of the cells in the brains began to show metabolic activity again, and some of the synapses even began firing.

How Humans Ended Up With Freakishly Huge Brains | WIRED - 0 views

  • paleontologists documented one of the most dramatic transitions in human evolution. We might call it the Brain Boom. Humans, chimps and bonobos split from their last common ancestor between 6 and 8 million years ago.
  • Starting around 3 million years ago, however, the hominin brain began a massive expansion. By the time our species, Homo sapiens, emerged about 200,000 years ago, the human brain had swelled from about 350 grams to more than 1,300 grams.
  • n that 3-million-year sprint, the human brain almost quadrupled the size its predecessors had attained over the previous 60 million years of primate evolution.
  • ...19 more annotations...
  • There are plenty of theories, of course, especially regarding why: increasingly complex social networks, a culture built around tool use and collaboration, the challenge of adapting to a mercurial and often harsh climate
  • Although these possibilities are fascinating, they are extremely difficult to test.
  • Although it makes up only 2 percent of body weight, the human brain consumes a whopping 20 percent of the body’s total energy at rest. In contrast, the chimpanzee brain needs only half that.
  • contrary to long-standing assumptions, larger mammalian brains do not always have more neurons, and the ones they do have are not always distributed in the same way.
  • The human brain has 86 billion neurons in all: 69 billion in the cerebellum, a dense lump at the back of the brain that helps orchestrate basic bodily functions and movement; 16 billion in the cerebral cortex, the brain’s thick corona and the seat of our most sophisticated mental talents, such as self-awareness, language, problem solving and abstract thought; and 1 billion in the brain stem and its extensions into the core of the brain
  • In contrast, the elephant brain, which is three times the size of our own, has 251 billion neurons in its cerebellum, which helps manage a giant, versatile trunk, and only 5.6 billion in its cortex
  • primates evolved a way to pack far more neurons into the cerebral cortex than other mammals did
  • The great apes are tiny compared to elephants and whales, yet their cortices are far denser: Orangutans and gorillas have 9 billion cortical neurons, and chimps have 6 billion. Of all the great apes, we have the largest brains, so we come out on top with our 16 billion neurons in the cortex.
  • “What kinds of mutations occurred, and what did they do? We’re starting to get answers and a deeper appreciation for just how complicated this process was.”
  • there was a strong evolutionary pressure to modify the human regulatory regions in a way that sapped energy from muscle and channeled it to the brain.
  • Accounting for body size and weight, the chimps and macaques were twice as strong as the humans. It’s not entirely clear why, but it is possible that our primate cousins get more power out of their muscles than we get out of ours because they feed their muscles more energy. “Compared to other primates, we lost muscle power in favor of sparing energy for our brains,” Bozek said. “It doesn’t mean that our muscles are inherently weaker. We might just have a different metabolism.
  • a pioneering experiment. Not only were they going to identify relevant genetic mutations from our brain’s evolutionary past, they were also going to weave those mutations into the genomes of lab mice and observe the consequences.
  • Silver and Wray introduced the chimpanzee copy of HARE5 into one group of mice and the human edition into a separate group. They then observed how the embryonic mice brains grew.
  • After nine days of development, mice embryos begin to form a cortex, the outer wrinkly layer of the brain associated with the most sophisticated mental talents. On day 10, the human version of HARE5 was much more active in the budding mice brains than the chimp copy, ultimately producing a brain that was 12 percent larger
  • “It wasn’t just a couple mutations and—bam!—you get a bigger brain. As we learn more about the changes between human and chimp brains, we realize there will be lots and lots of genes involved, each contributing a piece to that. The door is now open to get in there and really start understanding. The brain is modified in so many subtle and nonobvious ways.”
  • As recent research on whale and elephant brains makes clear, size is not everything, but it certainly counts for something. The reason we have so many more cortical neurons than our great-ape cousins is not that we have denser brains, but rather that we evolved ways to support brains that are large enough to accommodate all those extra cells.
  • There’s a danger, though, in becoming too enamored with our own big heads. Yes, a large brain packed with neurons is essential to what we consider high intelligence. But it’s not sufficient
  • No matter how large the human brain grew, or how much energy we lavished upon it, it would have been useless without the right body. Three particularly crucial adaptations worked in tandem with our burgeoning brain to dramatically increase our overall intelligence: bipedalism, which freed up our hands for tool making, fire building and hunting; manual dexterity surpassing that of any other animal; and a vocal tract that allowed us to speak and sing.
  • Human intelligence, then, cannot be traced to a single organ, no matter how large; it emerged from a serendipitous confluence of adaptations throughout the body. Despite our ongoing obsession with the size of our noggins, the fact is that our intelligence has always been so much bigger than our brain.

Human Brain: facts and information - 0 views

  • The human brain is more complex than any other known structure in the universe.
  • Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.
  • The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Animals such as elephants, dolphins, and whales actually have larger brains, but humans have the most developed cerebrum. It's packed to capacity inside our skulls, with deep folds that cleverly maximize the total surface area of the cortex.
  • ...18 more annotations...
  • The cerebrum has two halves, or hemispheres, that are further divided into four regions, or lobes. The frontal lobes, located behind the forehead, are involved with speech, thought, learning, emotion, and movement.
  • Behind them are the parietal lobes, which process sensory information such as touch, temperature, and pain.
  • At the rear of the brain are the occipital lobes, dealing with vision
  • Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.
  • The second-largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum.
  • diencephalon, located in the core of the brain. A complex of structures roughly the size of an apricot, its two major sections are the thalamus and hypothalamus
  • The brain is extremely sensitive and delicate, and so it requires maximum protection, which is provided by the hard bone of the skull and three tough membranes called meninges.
  • Want more proof that the brain is extraordinary? Look no further than the blood-brain barrier.
  • This led scientists to learn that the brain has an ingenious, protective layer. Called the blood-brain barrier, it’s made up of special, tightly bound cells that together function as a kind of semi-permeable gate throughout most of the organ. It keeps the brain environment safe and stable by preventing some toxins, pathogens, and other harmful substances from entering the brain through the bloodstream, while simultaneously allowing oxygen and vital nutrients to pass through.
  • One in five Americans suffers from some form of neurological damage, a wide-ranging list that includes stroke, epilepsy, and cerebral palsy, as well as dementia.
  • Alzheimer’s disease, which is characterized in part by a gradual progression of short-term memory loss, disorientation, and mood swings, is the most common cause of dementia. It is the sixth leading cause of death in the United States
  • 50 million people suffer from Alzheimer’s or some form of dementia. While there are a handful of drugs available to mitigate Alzheimer’s symptoms, there is no cure.
  • Unfortunately, negative attitudes toward people who suffer from mental illness are widespread. The stigma attached to mental illness can create feelings of shame, embarrassment, and rejection, causing many people to suffer in silence.
  • In the United States, where anxiety disorders are the most common forms of mental illness, only about 40 percent of sufferers receive treatment. Anxiety disorders often stem from abnormalities in the brain’s hippocampus and prefrontal cortex.
  • Attention-deficit/hyperactivity disorder, or ADHD, is a mental health condition that also affects adults but is far more often diagnosed in children.
  • ADHD is characterized by hyperactivity and an inability to stay focused.
  • Depression is another common mental health condition. It is the leading cause of disability worldwide and is often accompanied by anxiety. Depression can be marked by an array of symptoms, including persistent sadness, irritability, and changes in appetite.
  • The good news is that in general, anxiety and depression are highly treatable through various medications—which help the brain use certain chemicals more efficiently—and through forms of therapy

Which Type of Exercise Is Best for the Brain? - The New York Times - 1 views

  • Some forms of exercise may be much more effective than others at bulking up the brain, according to a remarkable new study in rats. For the first time, scientists compared head-to-head the neurological impacts of different types of exercise: running, weight training and high-intensity interval training. The surprising results suggest that going hard may not be the best option for long-term brain health.
  • exercise changes the structure and function of the brain. Studies in animals and people have shown that physical activity generally increases brain volume and can reduce the number and size of age-related holes in the brain’s white and gray matter.
  • Exercise also, and perhaps most resonantly, augments adult neurogenesis, which is the creation of new brain cells in an already mature brain. In studies with animals, exercise, in the form of running wheels or treadmills, has been found to double or even triple the number of new neurons that appear afterward in the animals’ hippocampus, a key area of the brain for learning and memory, compared to the brains of animals that remain sedentary. Scientists believe that exercise has similar impacts on the human hippocampus.
  • ...7 more annotations...
  • These past studies of exercise and neurogenesis understandably have focused on distance running. Lab rodents know how to run. But whether other forms of exercise likewise prompt increases in neurogenesis has been unknown and is an issue of increasing interest
  • new study, which was published this month in the Journal of Physiology, researchers at the University of Jyvaskyla in Finland and other institutions gathered a large group of adult male rats. The researchers injected the rats with a substance that marks new brain cells and then set groups of them to an array of different workouts, with one group remaining sedentary to serve as controls.
  • They found very different levels of neurogenesis, depending on how each animal had exercised. Those rats that had jogged on wheels showed robust levels of neurogenesis. Their hippocampal tissue teemed with new neurons, far more than in the brains of the sedentary animals. The greater the distance that a runner had covered during the experiment, the more new cells its brain now contained. There were far fewer new neurons in the brains of the animals that had completed high-intensity interval training. They showed somewhat higher amounts than in the sedentary animals but far less than in the distance runners. And the weight-training rats, although they were much stronger at the end of the experiment than they had been at the start, showed no discernible augmentation of neurogenesis. Their hippocampal tissue looked just like that of the animals that had not exercised at all.
  • “sustained aerobic exercise might be most beneficial for brain health also in humans.”
  • Just why distance running was so much more potent at promoting neurogenesis than the other workouts is not clear, although Dr. Nokia and her colleagues speculate that distance running stimulates the release of a particular substance in the brain known as brain-derived neurotrophic factor that is known to regulate neurogenesis. The more miles an animal runs, the more B.D.N.F. it produces. Weight training, on the other hand, while extremely beneficial for muscular health, has previously been shown to have little effect on the body’s levels of B.D.N.F.
  • As for high-intensity interval training, its potential brain benefits may be undercut by its very intensity, Dr. Nokia said. It is, by intent, much more physiologically draining and stressful than moderate running, and “stress tends to decrease adult hippocampal neurogenesis,” she said.
  • These results do not mean, however, that only running and similar moderate endurance workouts strengthen the brain, Dr. Nokia said. Those activities do seem to prompt the most neurogenesis in the hippocampus. But weight training and high-intensity intervals probably lead to different types of changes elsewhere in the brain. They might, for instance, encourage the creation of additional blood vessels or new connections between brain cells or between different parts of the brain.

  • After years of ignoring their critics, industry leaders are finally acknowledging that problems exist. Tech humanists deserve credit for drawing attention to one of those problems – the manipulative design decisions made by Silicon Valley.
  • these decisions are only symptoms of a larger issue: the fact that the digital infrastructures that increasingly shape our personal, social and civic lives are owned and controlled by a few billionaires
  • Because it ignores the question of power, the tech-humanist diagnosis is incomplete – and could even help the industry evade meaningful reform
  • Taken up by leaders such as Zuckerberg, tech humanism is likely to result in only superficial changes
  • they will not address the origin of that anger. If anything, they will make Silicon Valley even more powerful.
  • To the litany of problems caused by “technology that extracts attention and erodes society”, the text asserts that “humane design is the solution”. Drawing on the rhetoric of the “design thinking” philosophy that has long suffused Silicon Valley, the website explains that humane design “starts by understanding our most vulnerable human instincts so we can design compassionately”
  • this language is not foreign to Silicon Valley. On the contrary, “humanising” technology has long been its central ambition and the source of its power. It was precisely by developing a “humanised” form of computing that entrepreneurs such as Steve Jobs brought computing into millions of users’ everyday lives
  • Facebook had a new priority: maximising “time well spent” on the platform, rather than total time spent. By “time well spent”, Zuckerberg means time spent interacting with “friends” rather than businesses, brands or media sources. He said the News Feed algorithm was already prioritising these “more meaningful” activities.
  • Tech humanists say they want to align humanity and technology. But this project is based on a deep misunderstanding of the relationship between humanity and technology: namely, the fantasy that these two entities could ever exist in separation.
  • They believe we can use better design to make technology serve human nature rather than exploit and corrupt it. But this idea is drawn from the same tradition that created the world that tech humanists believe is distracting and damaging us.
  • The story of our species began when we began to make tools
  • All of which is to say: humanity and technology are not only entangled, they constantly change together.
  • This is not just a metaphor. Recent research suggests that the human hand evolved to manipulate the stone tools that our ancestors used
  • The ways our bodies and brains change in conjunction with the tools we make have long inspired anxieties that “we” are losing some essential qualities
  • Yet as we lose certain capacities, we gain new ones.
  • The nature of human nature is that it changes. It can not, therefore, serve as a stable basis for evaluating the impact of technology
  • Yet the assumption that it doesn’t change serves a useful purpose. Treating human nature as something static, pure and essential elevates the speaker into a position of power. Claiming to tell us who we are, they tell us how we should be.
  • Messaging, for instance, is considered the strongest signal. It’s reasonable to assume that you’re closer to somebody you exchange messages with than somebody whose post you once liked.
  • Harris and his fellow tech humanists also frequently invoke the language of public health. The Center for Humane Technology’s Roger McNamee has gone so far as to call public health “the root of the whole thing”, and Harris has compared using Snapchat to smoking cigarettes
  • The public-health framing casts the tech humanists in a paternalistic role. Resolving a public health crisis requires public health expertise. It also precludes the possibility of democratic debate. You don’t put the question of how to treat a disease up for a vote – you call a doctor.
  • They also remain confined to the personal level, aiming to redesign how the individual user interacts with technology rather than tackling the industry’s structural failures. Tech humanism fails to address the root cause of the tech backlash: the fact that a small handful of corporations own our digital lives and strip-mine them for profit.
  • This is a fundamentally political and collective issue. But by framing the problem in terms of health and humanity, and the solution in terms of design, the tech humanists personalise and depoliticise it.
  • Far from challenging Silicon Valley, tech humanism offers Silicon Valley a useful way to pacify public concerns without surrendering any of its enormous wealth and power.
  • these principles could make Facebook even more profitable and powerful, by opening up new business opportunities. That seems to be exactly what Facebook has planned.
  • reported that total time spent on the platform had dropped by around 5%, or about 50m hours per day. But, Zuckerberg said, this was by design: in particular, it was in response to tweaks to the News Feed that prioritised “meaningful” interactions with “friends” rather than consuming “public content” like video and news. This would ensure that “Facebook isn’t just fun, but also good for people’s well-being”
  • Zuckerberg said he expected those changes would continue to decrease total time spent – but “the time you do spend on Facebook will be more valuable”. This may describe what users find valuable – but it also refers to what Facebook finds valuable
  • not all data is created equal. One of the most valuable sources of data to Facebook is used to inform a metric called “coefficient”. This measures the strength of a connection between two users – Zuckerberg once called it “an index for each relationship”
  • Facebook records every interaction you have with another user – from liking a friend’s post or viewing their profile, to sending them a message. These activities provide Facebook with a sense of how close you are to another person, and different activities are weighted differently.
  • Holding humanity and technology separate clears the way for a small group of humans to determine the proper alignment between them
  • Why is coefficient so valuable? Because Facebook uses it to create a Facebook they think you will like: it guides algorithmic decisions about what content you see and the order in which you see it. It also helps improve ad targeting, by showing you ads for things liked by friends with whom you often interact
  • emphasising time well spent means creating a Facebook that prioritises data-rich personal interactions that Facebook can use to make a more engaging platform.
  • “time well spent” means Facebook can monetise more efficiently. It can prioritise the intensity of data extraction over its extensiveness. This is a wise business move, disguised as a concession to critics
  • industrialists had to find ways to make the time of the worker more valuable – to extract more money from each moment rather than adding more moments. They did this by making industrial production more efficient: developing new technologies and techniques that squeezed more value out of the worker and stretched that value further than ever before.
  • there is another way of thinking about how to live with technology – one that is both truer to the history of our species and useful for building a more democratic future. This tradition does not address “humanity” in the abstract, but as distinct human beings, whose capacities are shaped by the tools they use.
  • It sees us as hybrids of animal and machine – as “cyborgs”, to quote the biologist and philosopher of science Donna Haraway.
  • The cyborg way of thinking, by contrast, tells us that our species is essentially technological. We change as we change our tools, and our tools change us. But even though our continuous co-evolution with our machines is inevitable, the way it unfolds is not. Rather, it is determined by who owns and runs those machines. It is a question of power
  • The various scandals that have stoked the tech backlash all share a single source. Surveillance, fake news and the miserable working conditions in Amazon’s warehouses are profitable. If they were not, they would not exist. They are symptoms of a profound democratic deficit inflicted by a system that prioritises the wealth of the few over the needs and desires of the many.
  • If being technological is a feature of being human, then the power to shape how we live with technology should be a fundamental human right
  • The decisions that most affect our technological lives are far too important to be left to Mark Zuckerberg, rich investors or a handful of “humane designers”. They should be made by everyone, together.
  • Rather than trying to humanise technology, then, we should be trying to democratise it. We should be demanding that society as a whole gets to decide how we live with technology
  • What does this mean in practice? First, it requires limiting and eroding Silicon Valley’s power.
  • Antitrust laws and tax policy offer useful ways to claw back the fortunes Big Tech has built on common resources
  • democratic governments should be making rules about how those firms are allowed to behave – rules that restrict how they can collect and use our personal data, for instance, like the General Data Protection Regulation
  • This means developing publicly and co-operatively owned alternatives that empower workers, users and citizens to determine how they are run.
  • we might demand that tech firms pay for the privilege of extracting our data, so that we can collectively benefit from a resource we collectively create.

Scientists Are Attempting to Unlock the Secret Potential of the Human Brain | Big Think - 1 views

  • There are two ways for it to occur, either through an injury that causes brain damage or through a disorder, such as autism.
  • It’s estimated that around 50% of those with savant syndrome are autistic.
  • “The most common ability to emerge is art, followed by music,” Treffert told The Guardian. “But I’ve had cases where brain damage makes people suddenly interested in dance, or in Pinball Wizard.”

    This article reminds me of a scientific myth I saw one day about that people only use 10% percent of their brain. However, this description is not accurate because when we are using our brain, every parts of our brain is active and their is no vacant part of it. It is only that it has more potential than it seems. I think this description is 10% is misleading. I found the savant syndrome very interesting. I think this amazing talent in human brain is very amazing. So is it possible that the cognitive bias in human brain is because of the potential of human brain was not activated. --Sissi (4/17/2017)

Opinion | Richard Powers on What We Can Learn From Trees - The New York Times - 0 views

  • Theo and Robin have a nightly ritual where they say a prayer that Alyssa, the deceased wife and mother, taught them: May all sentient beings be free from needless suffering. That prayer itself comes from the four immeasurables in the Buddhist tradition.
  • When we enter into or recover this sense of kinship that was absolutely fundamental to so many indigenous cultures everywhere around the world at many, many different points in history, that there is no radical break between us and our kin, that even consciousness is shared, to some degree and to a large degree, with a lot of other creatures, then death stops seeming like the enemy and it starts seeming like one of the most ingenious kinds of design for keeping evolution circulating and keeping the experiment running and recombining.
  • Look, I’m 64 years old. I can remember sitting in psychology class as an undergraduate and having my professor declare that no, of course animals don’t have emotions because they don’t have an internal life. They don’t have conscious awareness. And so what looks to you like your dog being extremely happy or being extremely guilty, which dogs do so beautifully, is just your projection, your anthropomorphizing of those other creatures. And this prohibition against anthropomorphism created an artificial gulf between even those animals that are ridiculously near of kin to us, genetically.
  • ...62 more annotations...
  • I don’t know if that sounds too complicated. But the point is, it’s not just giving up domination. It’s giving up this sense of separateness in favor of a sense of kinship. And those people who do often wonder how they failed to see how much continuity there is in the more-than-human world with the human world.
  • to go from terror into being and into that sense that the experiment is sacred, not this one outcome of the experiment, is to immediately transform the way that you think even about very fundamental social and economic and cultural things. If the experiment is sacred, how can we possibly justify our food systems, for instance?
  • when I first went to the Smokies and hiked up into the old growth in the Southern Appalachians, it was like somebody threw a switch. There was some odd filter that had just been removed, and the world sounded different and smelled different.
  • richard powersYeah. In human exceptionalism, we may be completely aware of evolutionary continuity. We may understand that we have a literal kinship with the rest of creation, that all life on Earth employs the same genetic code, that there is a very small core of core genes and core proteins that is shared across all the kingdoms and phyla of life. But conceptually, we still have this demented idea that somehow consciousness creates a sanctity and a separation that almost nullifies the continuous elements of evolution and biology that we’ve come to understand.
  • if we want to begin this process of rehabilitation and transformation of consciousness that we are going to need in order to become part of the living Earth, it is going to be other kinds of minds that give us that clarity and strength and diversity and alternative way of thinking that could free us from this stranglehold of thought that looks only to the maximizing return on investment in very leverageable ways.
  • richard powersIt amazed me to get to the end of the first draft of “Bewilderment” and to realize how much Buddhism was in the book, from the simplest things.
  • I think there is nothing more science inflected than being out in the living world and the more-than-human world and trying to understand what’s happening.
  • And of course, we can combine this with what we were talking about earlier with death. If we see all of evolution as somehow leading up to us, all of human, cultural evolution leading up to neoliberalism and here we are just busily trying to accumulate and make meaning for ourselves, death becomes the enemy.
  • And you’re making the point in different ways throughout the book that it is the minds we think of as unusual, that we would diagnose as having some kind of problem or dysfunction that are, in some cases, are the only ones responding to the moment in the most common sense way it deserves. It is almost everybody else’s brain that has been broken.
  • it isn’t surprising. If you think of the characteristics of this dominant culture that we’ve been talking about — the fixation on control, the fixation on mastery, the fixation on management and accumulation and the resistance of decay — it isn’t surprising that that culture is also threatened by difference and divergence. It seeks out old, stable hierarchies — clear hierarchies — of control, and anything that’s not quite exploitable or leverageable in the way that the normal is terrifying and threatening.
  • And the more I looked for it, the more it pervaded the book.
  • ezra kleinI’ve heard you say that it has changed the way you measure a good day. Can you tell me about that?richard powersThat’s true.I suppose when I was still enthralled to commodity-mediated individualist market-driven human exceptionalism — we need a single word for this
  • And since moving to the Smokies and since publishing “The Overstory,” my days have been entirely inverted. I wake up, I go to the window, and I look outside. Or I step out onto the deck — if I haven’t been sleeping on the deck, which I try to do as much as I can in the course of the year — and see what’s in the air, gauge the temperature and the humidity and the wind and see what season it is and ask myself, you know, what’s happening out there now at 1,700 feet or 4,000 feet or 5,000 feet.
  • let me talk specifically about the work of a scientist who has herself just recently published a book. It’s Dr. Suzanne Simard, and the book is “Finding the Mother Tree.” Simard has been instrumental in a revolution in our way of thinking about what’s happening underground at the root level in a forest.
  • it was a moving moment for me, as an easterner, to stand up there and to say, this is what an eastern forest looks like. This is what a healthy, fully-functioning forest looks like. And I’m 56 years old, and I’d never seen it.
  • the other topics of that culture tend to circle back around these sorts of trends, human fascinations, ways of magnifying our throw weight and our ability and removing the last constraints to our desires and, in particular, to eliminate the single greatest enemy of meaning in the culture of the technological sublime that is, itself, such a strong instance of the culture of human separatism and commodity-mediated individualist capitalism— that is to say, the removal of death.
  • Why is it that we have known about the crisis of species extinction for at least half a century and longer? And I mean the lay public, not just scientists. But why has this been general knowledge for a long time without public will demanding some kind of action or change
  • And when you make kinship beyond yourself, your sense of meaning gravitates outwards into that reciprocal relationship, into that interdependence. And you know, it’s a little bit like scales falling off your eyes. When you do turn that corner, all of the sources of anxiety that are so present and so deeply internalized become much more identifiable. And my own sense of hope and fear gets a much larger frame of reference to operate in.
  • I think, for most of my life, until I did kind of wake up to forests and to trees, I shared — without really understanding this as a kind of concession or a kind of subscription — I did share this cultural consensus that meaning is a private thing that we do for ourselves and by ourselves and that our kind of general sense of the discoveries of the 19th and 20th century have left us feeling a bit unsponsored and adrift beyond the accident of human existence.
  • The largest single influence on any human being’s mode of thought is other human beings. So if you are surrounded by lots of terrified but wishful-thinking people who want to believe that somehow the cavalry is going to come at the last minute and that we don’t really have to look inwards and change our belief in where meaning comes from, that we will somehow be able to get over the finish line with all our stuff and that we’ll avert this disaster, as we have other kinds of disasters in the past.
  • I think what was happening to me at that time, as I was turning outward and starting to take the non-human world seriously, is my sense of meaning was shifting from something that was entirely about me and authored by me outward into this more collaborative, reciprocal, interdependent, exterior place that involved not just me but all of these other ways of being that I could make kinship with.
  • And I think I was right along with that sense that somehow we are a thing apart. We can make purpose and make meaning completely arbitrarily. It consists mostly of trying to be more in yourself, of accumulating in one form or another.
  • I can’t really be out for more than two or three miles before my head just fills with associations and ideas and scenes and character sketches. And I usually have to rush back home to keep it all in my head long enough to get it down on paper.
  • for my journey, the way to characterize this transition is from being fascinated with technologies of mastery and control and what they’re doing to us as human beings, how they’re changing what the capacities and affordances of humanity are and how we narrate ourselves, to being fascinated with technologies and sciences of interdependence and cooperation, of those sciences that increase our sense of kinship and being one of many, many neighbors.
  • And that’s an almost impossible persuasion to rouse yourself from if you don’t have allies. And I think the one hopeful thing about the present is the number of people trying to challenge that consensual understanding and break away into a new way of looking at human standing is growing.
  • And when you do subscribe to a culture like that and you are confronted with the reality of your own mortality, as I was when I was living in Stanford, that sense of stockpiling personal meaning starts to feel a little bit pointless.
  • And I just head out. I head out based on what the day has to offer. And to have that come first has really changed not only how I write, but what I’ve been writing. And I think it really shows in “Bewilderment.” It’s a totally different kind of book from my previous 12.
  • the marvelous thing about the work, which continues to get more sophisticated and continues to turn up newer and newer astonishments, is that there was odd kind of reciprocal interdependence and cooperation across the species barrier, that Douglas firs and birches were actually involved in these sharing back and forth of essential nutrients. And that’s a whole new way of looking at forest.
  • she began to see that the forests were actually wired up in very complex and identifiable ways and that there was an enormous system of resource sharing going on underground, that trees were sharing not only sugars and the hydrocarbons necessary for survival, but also secondary metabolites. And these were being passed back and forth, both symbiotically between the trees and the fungi, but also across the network to other trees so that there were actually trees in wired up, fungally-connected forests where large, dominant, healthy trees were subsidizing, as it were, trees that were injured or not in favorable positions or damaged in some way or just failing to thrive.
  • so when I was still pretty much a card-carrying member of that culture, I had this sense that to become a better person and to get ahead and to really make more of myself, I had to be as productive as possible. And that meant waking up every morning and getting 1,000 words that I was proud of. And it’s interesting that I would even settle on a quantitative target. That’s very typical for that kind of mindset that I’m talking about — 1,000 words and then you’re free, and then you can do what you want with the day.
  • there will be a threshold, as there have been for these other great social transformations that we’ve witnessed in the last couple of decades where somehow it goes from an outsider position to absolutely mainstream and common sense.
  • I am persuaded by those scholars who have showed the degree to which the concept of nature is itself an artificial construction that’s born of cultures of human separatism. I believe that everything that life does is part of the living enterprise, and that includes the construction of cities. And there is no question at all the warning that you just gave about nostalgia creating a false binary between the built world and the true natural world is itself a form of cultural isolation.
  • Religion is a technology to discipline, to discipline certain parts of the human impulse. A lot of the book revolves around the decoded neurofeedback machine, which is a very real literalization of a technology, of changing the way we think
  • one of the things I think that we have to take seriously is that we have created technologies to supercharge some parts of our natural impulse, the capitalism I think should be understood as a technology to supercharge the growth impulse, and it creates some wonders out of that and some horrors out of that.
  • richard powersSure. I base my machine on existing technology. Decoded neurofeedback is a kind of nascent field of exploration. You can read about it; it’s been publishing results for a decade. I first came across it in 2013. It involves using fMRI to record the brain activity of a human being who is learning a process, interacting with an object or engaged in a certain emotional state. That neural activity is recorded and stored as a data structure. A second subsequent human being is then also scanned in real time and fed kinds of feedback based on their own internal neural activity as determined by a kind of software analysis of their fMRI data structures.
  • And they are queued little by little to approximate, to learn how to approximate, the recorded states of the original subject. When I first read about this, I did get a little bit of a revelation. I did feel my skin pucker and think, if pushed far enough, this would be something like a telepathy conduit. It would be a first big step in answering that age-old question of what does it feel like to be something other than we are
  • in the book I simply take that basic concept and extend it, juke it up a little bit, blur the line between what the reader might think is possible right now and what they might wonder about, and maybe even introduce possibilities for this empathetic transference
  • ezra kleinOne thing I loved about the role this played in the book is that it’s highlighting its inverse. So a reader might look at this and say, wow, wouldn’t that be cool if we had a machine that could in real time change how we think and change our neural pathways and change our mental state in a particular direction? But of course, all of society is that machine,
  • Robin and Theo are in an airport. And you’ve got TVs everywhere playing the news which is to say playing a constant loop of outrage, and disaster, and calamity. And Robbie, who’s going through these neural feedback sessions during this period, turns to his dad and says, “Dad, you know how the training’s rewiring my brain? This is what is rewiring everybody else.”
  • ezra kleinI think Marshall McLuhan knew it all. I really do. Not exactly what it would look like, but his view and Postman’s view that we are creating a digital global nervous system is a way they put it, it was exactly right. A nervous system, it was such the exact right metaphor.
  • the great insight of McLuhan, to me, what now gets called the medium is the message is this idea that the way media acts upon us is not in the content it delivers. The point of Twitter is not the link that you click or even the tweet that you read; it is that the nature and structure of the Twitter system itself begins to act on your system, and you become more like it.If you watch a lot of TV, you become more like TV. If you watch a lot of Twitter, you become more like Twitter, Facebook more like Facebook. Your identities become more important to you — that the content is distraction from the medium, and the medium changes you
  • it is happening to all of us in ways that at least we are not engaging in intentionally, not at that level of how do we want to be transformed.
  • richard powersI believe that the digital neural system is now so comprehensive that the idea that you could escape it somewhere, certainly not in the Smokies, even more remotely, I think, becomes more and more laughable. Yeah, and to build on this idea of the medium being the message, not the way in which we become more like the forms and affordances of the medium is that we begin to expect that those affordances, the method in which those media are used, the physiological dependencies and castes of behavior and thought that are required to operate them and interact with them are actual — that they’re real somehow, and that we just take them into human nature and say no, this is what we’ve always wanted and we’ve simply been able to become more like our true selves.
  • Well, the warpage in our sense of time, the warpage in our sense of place, are profound. The ways in which digital feedback and the affordances of social media and all the rest have changed our expectations with regard to what we need to concentrate on, what we need to learn for ourselves, are changing profoundly.
  • If you look far enough back, you can find Socrates expressing great anxiety and suspicion about the ways in which writing is going to transform the human brain and human expectation. He was worried that somehow it was going to ruin our memories. Well, it did up to a point — nothing like the way the digital technologies have ruined our memories.
  • my tradition is Jewish, the Sabbath is a technology, is a technology to create a different relationship between the human being, and time, and growth, and productive society than you would have without the Sabbath which is framed in terms of godliness but is also a way of creating separation from the other impulses of the weak.
  • Governments are a technology, monogamy is a technology, a religiously driven technology, but now one that is culturally driven. And these things do good and they do bad. I’m not making an argument for any one of them in particular. But the idea that we would need to invent something wholly new to come up with a way to change the way human beings act is ridiculous
  • My view of the story of this era is that capitalism was one of many forces, and it has become, in many societies, functionally the only one that it was in relationship with religion, it was in relationship with more rooted communities.
  • it has become not just an economic system but a belief system, and it’s a little bit untrammeled. I’m not an anti-capitalist person, but I believe it needs countervailing forces. And my basic view is that it doesn’t have them anymore.
  • the book does introduce this kind of fable, this kind of thought experiment about the way the affordances that a new and slightly stronger technology of empathy might deflect. First of all, the story of a little boy and then the story of his father who’s scrambling to be a responsible single parent. And then, beyond that, the community of people who hear about this boy and become fascinated with him as a narrative, which again ripples outward through these digital technologies in ways that can’t be controlled or whose consequences can be foreseen.
  • I’ve talked about it before is something I’ve said is that I think a push against, functionally, materialism and want is an important weight in our society that we need. And when people say it is the way we’ll deal with climate change in the three to five year time frame, I become much more skeptical because to the point of things like the technology you have in the book with neural feedback, I do think one of the questions you have to ask is, socially and culturally, how do you move people’s minds so you can then move their politics?
  • You’re going to need something, it seems to me, outside of politics, that changes humans’ sense of themselves more fundamentally. And that takes a minute at the scale of billions.
  • richard powersWell, you are correct. And I don’t think it’s giving away any great reveal in the book to say that a reader who gets far enough into the story probably has this moment of recursive awareness where they, he or she comes to understand that what Robin is doing in this gradual training on the cast of mind of some other person is precisely what they’re doing in the act of reading the novel “Bewilderment” — by living this act of active empathy for these two characters, they are undergoing their own kind of neurofeedback.
  • The more we understand about the complexities of living systems, of organisms and the evolution of organisms, the more capable it is to feel a kind of spiritual awe. And that certainly makes it easier to have reverence for the experiment beyond me and beyond my species. I don’t think those are incommensurable or incompatible ways of knowing the world. In fact, I think to invoke one last time that Buddhist precept of interbeing, I think there is a kind of interbeing between the desire, the true selfless desire to understand the world out there through presence, care, measurement, attention, reproduction of experiment and the desire to have a spiritual affinity and shared fate with the world out there. They’re really the same project.
  • richard powersWell, sure. If we turn back to the new forestry again and researchers like Suzanne Simard who were showing the literal interconnectivity across species boundaries and the cooperation of resource sharing between different species in a forest, that is rigorous science, rigorous reproducible science. And it does participate in that central principle of practice, or collection of practices, which always requires the renunciation of personal wish and ego and prior belief in favor of empirical reproduction.
  • I’ve begun to see people beginning to build out of the humbling sciences a worldview that seems quite spiritual. And as you’re somebody who seems to me to have done that and it has changed your life, would you reflect on that a bit?
  • So much of the book is about the possibility of life beyond Earth. Tell me a bit about the role that’s playing. Why did you make the possibility of alien life in the way it might look and feel and evolve and act so central in a book about protecting and cherishing life here?
  • richard powersI’m glad that we’re slipping this in at the end because yes this framing of the book around this question of are we alone or does the universe want life it’s really important. Theo, Robin’s father, is an astrobiologist.
  • Imagine that everything happens just right so that every square inch of this place is colonized by new forms of experiments, new kinds of life. And the father trying to entertain his son with the story of this remarkable place in the sun just stopping him and saying, Dad, come on, that’s asking too much. Get real, that’s science fiction. That’s the vision that I had when I finished the book, an absolutely limitless sense of just how lucky we’ve had it here.
  • one thing I kept thinking about that didn’t make it into the final book but exists as a kind of parallel story in my own head is the father and son on some very distant planet in some very distant star, many light years from here, playing that same game. And the father saying, OK, now imagine a world that’s just the right size, and it has plate tectonics, and it has water, and it has a nearby moon to stabilize its rotation, and it has incredible security and safety from asteroids because of other large planets in the solar system.
  • they make this journey across the universe through all kinds of incubators, all kinds of petri dishes for life and the possibilities of life. And rather than answer the question — so where is everybody? — it keeps deferring the question, it keeps making that question more subtle and stranger
  • For the purposes of the book, Robin, who desperately believes in the sanctity of life beyond himself, begs his father for these nighttime, bedtime stories, and Theo gives him easy travel to other planets. Father and son going to a new planet based on the kinds of planets that Theo’s science is turning up and asking this question, what would life look like if it was able to get started here?

Humans, Version 3.0 § SEEDMAGAZINE.COM - 0 views

  • Where are we humans going, as a species? If science fiction is any guide, we will genetically evolve like in X-Men, become genetically engineered as in Gattaca, or become cybernetically enhanced like General Grievous in Star Wars.
  • There is, however, another avenue for human evolution, one mostly unappreciated in both science and fiction. It is this unheralded mechanism that will usher in the next stage of human, giving future people exquisite powers we do not currently possess, powers worthy of natural selection itself. And, importantly, it doesn’t require us to transform into cyborgs or bio-engineered lab rats. It merely relies on our natural bodies and brains functioning as they have for millions of years. This mystery mechanism of human transformation is neuronal recycling, coined by neuroscientist Stanislas Dehaene, wherein the brain’s innate capabilities are harnessed for altogether novel functions.
  • The root of these misconceptions is the radical underappreciation of the design engineered by natural selection into the powers implemented by our bodies and brains, something central to my 2009 book, The Vision Revolution. For example, optical illusions (such as the Hering) are not examples of the brain’s poor hardware design, but, rather, consequences of intricate evolutionary software for generating perceptions that correct for neural latencies in normal circumstances.

  • Like all animal brains, human brains are not general-purpose universal learning machines, but, instead, are intricately structured suites of instincts optimized for the environments in which they evolved. To harness our brains, we want to let the brain’s brilliant mechanisms run as intended—i.e., not to be twisted. Rather, the strategy is to twist Y into a shape that the brain does know how to process.
  • there is a very good reason to be optimistic that the next stage of human will come via the form of adaptive harnessing, rather than direct technological enhancement: It has already happened. We have already been transformed via harnessing beyond what we once were. We’re already Human 2.0, not the Human 1.0, or Homo sapiens, that natural selection made us. We Human 2.0’s have, among many powers, three that are central to who we take ourselves to be today: writing, speech, and music (the latter perhaps being the pinnacle of the arts). Yet these three capabilities, despite having all the hallmarks of design, were not a result of natural selection, nor were they the result of genetic engineering or cybernetic enhancement to our brains. Instead, and as I argue in both The Vision Revolution and my forthcoming Harnessed, these are powers we acquired by virtue of harnessing, or neuronal recycling.
  • Although the step from Human 1.0 to 2.0 was via cultural selection, not via explicit human designers, does the transformation to Human 3.0 need to be entirely due to a process like cultural evolution, or might we have any hope of purposely guiding our transformation? When considering our future, that’s probably the most relevant question we should be asking ourselves.
  • One of my reasons for optimism is that nature-harnessing technologies (like writing, speech, and music) must mimic fundamental ecological features in nature, and that is a much easier task for scientists to tackle than emulating the exhorbitantly complex mechanisms of the brain

Science: A New Map of the Human Brain - WSJ.com - 0 views

  • The popular left/right story has no solid basis in science. The brain doesn't work one part at a time, but rather as a single interactive system, with all parts contributing in concert, as neuroscientists have long known. The left brain/right brain story may be the mother of all urban legends: It sounds good and seems to make sense—but just isn't true.
  • There is a better way to understand the functioning of the brain, based on another, ordinarily overlooked anatomical division—between its top and bottom parts. We call this approach "the theory of cognitive modes." Built on decades of unimpeachable research that has largely remained inside scientific circles, it offers a new way of viewing thought and behavior
  • Our theory has emerged from the field of neuropsychology, the study of higher cognitive functioning—thoughts, wishes, hopes, desires and all other aspects of mental life. Higher cognitive functioning is seated in the cerebral cortex, the rind-like outer layer of the brain that consists of four lobes
  • ...19 more annotations...
  • The top brain comprises the entire parietal lobe and the top (and larger) portion of the frontal lobe. The bottom comprises the smaller remainder of the frontal lobe and all of the occipital and temporal lobes.
  • research reveals that the top-brain system uses information about the surrounding environment (in combination with other sorts of information, such as emotional reactions and the need for food or drink) to figure out which goals to try to achieve. It actively formulates plans, generates expectations about what should happen when a plan is executed and then, as the plan is being carried out, compares what is happening with what was expected, adjusting the plan accordingly.
  • The bottom-brain system organizes signals from the senses, simultaneously comparing what is being perceived with all the information previously stored in memory. It then uses the results of such comparisons to classify and interpret the object or event, allowing us to confer meaning on the world.
  • The top- and bottom-brain systems always work together, just as the hemispheres always do. Our brains are not engaged in some sort of constant cerebral tug of war
  • Although the top and bottom parts of the brain are always used during all of our waking lives, people do not rely on them to an equal degree. To extend the bicycle analogy, not everyone rides a bike the same way. Some may meander, others may race.
  • You can use the top-brain system to develop simple and straightforward plans, as required by a situation—or you have the option to use it to develop detailed and complex plans (which are not imposed by a situation).
  • Our theory predicts that people fit into one of four groups, based on their typical use of the two brain systems. Depending on the degree to which a person uses the top and bottom systems in optional ways, he or she will operate in one of four cognitive modes: Mover, Perceiver, Stimulator and Adaptor.
  • Mover mode results when the top- and bottom-brain systems are both highly utilized in optional ways. Oprah Winfrey
  • Perceiver mode results when the bottom-brain system is highly utilized in optional ways but the top is not. Think of the Dalai Lama or Emily Dickinson
  • According to the theory, people who habitually rely on Mover mode are most comfortable in positions that allow them to plan, act and see the consequences of their actions. They are well suited to being leaders.
  • People who habitually rely on Perceiver mode try to make sense in depth of what they perceive; they interpret their experiences, place them in context and try to understand the implications.
  • such people—including naturalists, pastors, novelists—typically lead lives away from the limelight. Those who rely on this mode often play a crucial role in a group; they can make sense of events and provide a bigger picture
  • Stimulator mode, which results when the top-brain system is highly utilized but the bottom is not. According to our theory, people who interact with the world in Stimulator mode often create and execute complex and detailed plans (using the top-brain system) but fail to register consistently and accurately the consequences of acting on those plans
  • they may not always note when enough is enough. Their actions can be disruptive, and they may not adjust their behavior appropriately.
  • Examples of people who illustrate Stimulator mode would include Tiger Woods
  • Adaptor mode, which results when neither the top- nor the bottom-brain system is highly utilized in optional ways. People who think in this mode are not caught up in initiating plans, nor are they fully focused on classifying and interpreting what they experience. Instead, they become absorbed by local events and the immediate requirements of the situation
  • They are responsive and action-oriented and tend to "go with the flow." Others see them as free-spirited and fun to be with.
  • those who typically operate in Adaptor mode can be valuable team members. In business, they often form the backbone of an organization, carrying out essential operations.
  • No one mode is "better" than the others. Each is more or less useful in different circumstances, and each contributes something useful to a team. Our theory leads us to expect that you can work with others most productively when you are aware not just of the strengths and weakness of their preferred modes but also of the strengths and weakness of your own preferred mode

How Do We Learn Languages? | Brain Blogger - 0 views

  • The use of sound is one of the most common methods of communication both in the animal kingdom and between humans.
  • human speech is a very complex process and therefore needs intensive postnatal learning to be used effectively. Furthermore, to be effective the learning phase should happen very early in life and it assumes a normally functioning hearing and brain systems.
  • Nowadays, scientists and doctors are discovering the important brain zones involved in the processing of language information. Those zones are reassembled in a number of a language networks including the Broca, the Wernicke, the middle temporal, the inferior parietal and the angular gyrus. The variety of such brain zones clearly shows that the language processing is a very complex task. On the functional level, decoding a language begins in the ear where the incoming sounds are summed in the auditory nerve as an electrical signal and delivered to the auditory cortex where neurons extract auditory objects from that signal.
  • ...6 more annotations...
  • The effectiveness of this process is so great that human brain is able to accurately identify words and whole phrases from a noisy background. This power of analysis brings to minds the great similarity between the brain and powerful supercomputers.
  • Functional imaging of the brain revealed that activated brain parts are different between native and non-native speakers. The superior temporal gyrus is an important brain region involved in language learning. For a native speaker this part is responsible for automated processing of lexical retrieval and the build of phrase structure. In native speakers this zone is much more activated than in non-native ones.
  • infants begin their lives with a very flexible brain that allows them to acquire virtually any language they are exposed to. Moreover, they can learn a language words almost equally by listening or by visual coding. This brain plasticity is the motor drive of the children capability of “cracking the speech code” of a language. With time, this ability is dramatically decreased and adults find it harder to acquire a new language.
  • clearly demonstrated that there are anatomical brain differences between fast and slow learners of foreign languages. By analyzing a group of people having a homogenous language background, scientists found that differences in specific brain regions can predict the capacity of a person to learn a second language.
  • Until the last decade few studies compared the language acquisition in adults and children. Thanks to modern imaging and electroencephalography we are now able to address this question.
  • Language acquisition is a long-term process by which information are stored in the brain unconsciously making them appropriate to oral and written usage. In contrast, language learning is a conscious process of knowledge acquisition that needs supervision and control by the person.

In the Human Brain, Size Really Isn't Everything - NYTimes.com - 0 views

  • There are many things that make humans a unique species, but a couple stand out. One is our mind, the other our brain.
  • The human mind can carry out cognitive tasks that other animals cannot, like using language, envisioning the distant future and inferring what other people are thinking.
  • Scientists have long suspected that our big brain and powerful mind are intimately connected. Starting about three million years ago, fossils of our ancient relatives record a huge increase in brain size. Once that cranial growth was underway, our forerunners started leaving behind signs of increasingly sophisticated minds, like stone tools and cave paintings.
  • ...6 more annotations...
  • In our smaller-brained ancestors, the researchers argue, neurons were tightly tethered in a relatively simple pattern of connections. When our ancestors’ brains expanded, those tethers ripped apart, enabling our neurons to form new circuits.
  • There are cortices for the other senses, too. The sensory cortices relay signals to another set of regions called motor cortices. The motor cortices send out commands. This circuit is good for controlling basic mammal behavior. “You experience something in the world and you respond to it,” Dr. Krienen said.
  • After mammals are born, their experiences continue to strengthen this wiring. As a mammal sees more of the world, for example, neurons in the visual cortex form more connections to the motor cortices, so that the bucket brigade moves faster and more efficiently.
  • Human brains are different. As they got bigger, their sensory and motor cortices barely expanded. Instead, it was the regions in between, known as the association cortices, that bloomed. Our association cortices are crucial for the kinds of thought that we humans excel at. Among other tasks, association cortices are crucial for making decisions, retrieving memories and reflecting on ourselves.
  • Association cortices are also unusual for their wiring. They are not connected in the relatively simple, bucket-brigade pattern found in other mammal brains. Instead, they link to one another with wild abandon. A map of association cortices looks less like an assembly line and more like the Internet, with each region linked to others near and far.
  • This new wiring may have been crucial to the evolution of the human mind. Our association cortices liberate us from the rapid responses of other mammal brains. These new brain regions can communicate without any input from the outside world, discovering new insights about our environment and ourselves.

YaleNews | Yale researchers map 'switches' that shaped the evolution of the human brain - 0 views

  • Thousands of genetic “dimmer” switches, regions of DNA known as regulatory elements, were turned up high during human evolution in the developing cerebral cortex, according to new research from the Yale School of Medicine.
  • these switches show increased activity in humans, where they may drive the expression of genes in the cerebral cortex, the region of the brain that is involved in conscious thought and language. This difference may explain why the structure and function of that part of the brain is so unique in humans compared to other mammals.
  • Noonan and his colleagues pinpointed several biological processes potentially guided by these regulatory elements that are crucial to human brain development.
  • ...7 more annotations...
  • “Building a more complex cortex likely involves several things: making more cells, modifying the functions of cortical areas, and changing the connections neurons make with each other
  • Scientists have become adept at comparing the genomes of different species to identify the DNA sequence changes that underlie those differences. But many human genes are very similar to those of other primates, which suggests that changes in the way genes are regulated — in addition to changes in the genes themselves — is what sets human biology apart.
  • First, Noonan and his colleagues mapped active regulatory elements in the human genome during the first 12 weeks of cortical development by searching for specific biochemical, or “epigenetic” modifications
  • same in the developing brains of rhesus monkeys and mice, then compared the three maps to identify those elements that showed greater activity in the developing human brain.
  • wanted to know the biological impact of those regulatory changes.
  • They used those data to identify groups of genes that showed coordinated expression in the cerebral cortex.
  • “While we often think of the human brain as a highly innovative structure, it’s been surprising that so many of these regulatory elements seem to play a role in ancient processes important for building the cortex in all mammals, said first author Steven Reilly

Face It, Your Brain Is a Computer - The New York Times - 0 views

  • all the standard arguments about why the brain might not be a computer are pretty weak.
  • Take the argument that “brains are parallel, but computers are serial.” Critics are right to note that virtually every time a human does anything, many different parts of the brain are engaged; that’s parallel, not serial.
  • the trend over time in the hardware business has been to make computers more and more parallel, using new approaches like multicore processors and graphics processing units.
  • ...6 more annotations...
  • The real payoff in subscribing to the idea of a brain as a computer would come from using that idea to profitably guide research. In an article last fall in the journal Science, two of my colleagues (Adam Marblestone of M.I.T. and Thomas Dean of Google) and I endeavored to do just that, suggesting that a particular kind of computer, known as the field programmable gate array, might offer a preliminary starting point for thinking about how the brain works.
  • FIELD programmable gate arrays consist of a large number of “logic block” programs that can be configured, and reconfigured, individually, to do a wide range of tasks. One logic block might do arithmetic, another signal processing, and yet another look things up in a table. The computation of the whole is a function of how the individual parts are configured. Much of the logic can be executed in parallel, much like what happens in a brain.
  • our suggestion is that the brain might similarly consist of highly orchestrated sets of fundamental building blocks, such as “computational primitives” for constructing sequences, retrieving information from memory, and routing information between different locations in the brain. Identifying those building blocks, we believe, could be the Rosetta stone that unlocks the brain.
  • it is unlikely that we will ever be able to directly connect the language of neurons and synapses to the diversity of human behavior, as many neuroscientists seem to hope. The chasm between brains and behavior is just too vast.
  • Our best shot may come instead from dividing and conquering. Fundamentally, that may involve two steps: finding some way to connect the scientific language of neurons and the scientific language of computational primitives (which would be comparable in computer science to connecting the physics of electrons and the workings of microprocessors); and finding some way to connect the scientific language of computational primitives and that of human behavior (which would be comparable to understanding how computer programs are built out of more basic microprocessor instructions).
  • If neurons are akin to computer hardware, and behaviors are akin to the actions that a computer performs, computation is likely to be the glue that binds the two.

A new atlas maps word meanings in the brain | PBS NewsHour - 0 views

  • like Google Maps for your cerebral cortex: A new interactive atlas, developed with the help of such unlikely tools as public radio podcasts and Wikipedia, purports to show which bits of your brain help you understand which types of concepts.

  • The research on the “brain dictionary” has the hallmarks of a big scientific splash: Published on Wednesday in Nature, it’s accompanied by both a video and an interactive website where you can click your way from brain region to brain region, seeing what kinds of words are processed in each. Yet neuroscientists aren’t uniformly impressed.

  • invoked an old metaphor to explain why he isn’t convinced by the analysis: He compared it to establishing a theory of how weather works by pointing a video camera out the window for 7 hours.
  • Indeed, among neuroscientists, the new “comprehensive atlas” of the cerebral cortex is almost as controversial as a historical atlas of the Middle East. That’s because every word has a constellation of meanings and associations — and it’s hard for scientists to agree about how best to study them in the lab.
  • For this study, neuroscientist Jack Gallant and his team at the University of California, Berkeley played more than two hours’ worth of stories from the Moth Radio Hour for seven grad students and postdocs while measuring their cerebral blood flow using functional magnetic resonance imaging. Then, they linked the activity in some 50,000 pea-sized regions of the cortex to the “meaning” of the words being heard at that moment.
  • How, you might ask, did they establish the meaning of words? The neuroscientists pulled all the nouns and verbs from the podcasts. With a computer program, they then looked across millions of pages of text to see how often the words from the podcasts are used near 985 common words taken from Wikipedia’s List of 1,000 Basic Words. “Wolf,” for instance, would presumably be used more often in proximity to “dog” than to, say, “eggplant.” Using that data, the program assigned numbers that approximated the meaning of each individual word from the podcasts — and, with some fancy number crunching, they figured out what areas of the brain were activated when their research subjects heard words with certain meanings.
  • Everyone agrees that the research is innovative in its method. After all, linking up the meanings of thousands of words to the second-by-second brain activity in thousands of tiny brain regions is no mean feat. “That’s way more data than any human being can possibly think about,” said Gallant.
  • What they can’t agree on is what it means. “In this study, our goal was not to ask a specific question. Our goal was to map everything so that we can ask questions after that,” said Gallant. “One of the most frequent questions we get is, ‘What does it mean?’ If I gave you a globe, you wouldn’t ask what it means, you’d start using it for stuff. You can look for the smallest ocean or how long it will take to get to San Francisco.”
  • This “data-driven approach” still involves assumptions about how to break up language into different categories of meaning
  • “Of course it’s a very simplified version of how meaning is captured in our minds, but it seems to be a pretty good proxy,” she said.
  • hordes of unanswered questions: “We can map where your brain represents the meaning of a narrative text that is associated with family, but we don’t know why the brain is responding to family at that location. Is it the word ‘father’ itself? Is it your memories of your own father? Is it your own thinking about being a parent yourself?” He hopes that it’s just those types of questions that researchers will ask, using his brain map as a guide.

TikTok Brain Explained: Why Some Kids Seem Hooked on Social Video Feeds - WSJ - 0 views

  • Remember the good old days when kids just watched YouTube all day? Now that they binge on 15-second TikToks, those YouTube clips seem like PBS documentaries.
  • Many parents tell me their kids can’t sit through feature-length films anymore because to them the movies feel painfully slow. Others have observed their kids struggling to focus on homework. And reading a book? Forget about it.

  • “It is hard to look at increasing trends in media consumption of all types, media multitasking and rates of ADHD in young people and not conclude that there is a decrease in their attention span,
  • Emerging research suggests that watching short, fast-paced videos makes it harder for kids to sustain activities that don’t offer instant—and constant—gratification.
  • One of the few studies specifically examining TikTok-related effects on the brain focused on Douyin, the TikTok equivalent in China, made by the same Chinese parent company, ByteDance Ltd. It found that the personalized videos the app’s recommendation engine shows users activate the reward centers of the brain, as compared with the general-interest videos shown to new users.
  • Brain scans of Chinese college students showed that areas involved in addiction were highly activated in those who watched personalized videos.
  • It also found some people have trouble controlling when to stop watching.

  • A TikTok spokeswoman said the company wants younger teens to develop positive digital habits early on, and that it recently made some changes aimed at curbing extensive app usage. For example, TikTok won’t allow users ages 13 to 15 to receive push notifications after 9 p.m. TikTok also periodically reminds users to take a break to go outside or grab a snack.
  • Kids have a hard time pulling away from videos on YouTube, too, and Google has made several changes to help limit its use, including turning off autoplay by default on accounts of people under 18.
  • When kids do things that require prolonged focus, such as reading or solving math problems, they’re using directed attention
  • This function starts in the prefrontal cortex, the part of the brain responsible for decision making and impulse control.
  • “Directed attention is the ability to inhibit distractions and sustain attention and to shift attention appropriately. It requires higher-order skills like planning and prioritizing,”
  • Kids generally have a harder time doing this—and putting down their videogame controllers—because the prefrontal cortex isn’t fully developed until age 25.
  • “We speculate that individuals with lower self-control ability have more difficulty shifting attention away from favorite video stimulation,
  • “In the short-form snackable world, you’re getting quick hit after quick hit, and as soon as it’s over, you have to make a choice,” said Mass General’s Dr. Marci, who wrote the new book “Rewired: Protecting Your Brain in the Digital Age.” The more developed the prefrontal cortex, the better the choices.
  • Dopamine is a neurotransmitter that gets released in the brain when it’s expecting a reward. A flood of dopamine reinforces cravings for something enjoyable, whether it’s a tasty meal, a drug or a funny TikTok video.
  • “TikTok is a dopamine machine,” said John Hutton, a pediatrician and director of the Reading & Literacy Discovery Center at Cincinnati Children’s Hospital. “If you want kids to pay attention, they need to practice paying attention.”
  • Researchers are just beginning to conduct long-term studies on digital media’s effects on kids’ brains. The National Institutes of Health is funding a study of nearly 12,000 adolescents as they grow into adulthood to examine the impact that many childhood experiences—from social media to smoking—have on cognitive development.
  • she predicts they will find that when brains repeatedly process rapid, rewarding content, their ability to process less-rapid, less-rewarding things “may change or be harmed.”
  • “It’s like we’ve made kids live in a candy store and then we tell them to ignore all that candy and eat a plate of vegetables,”
  • “We have an endless flow of immediate pleasures that’s unprecedented in human history.”
  • Parents and kids can take steps to boost attention, but it takes effort
  • Swap screen time for real time. Exercise and free play are among the best ways to build attention during childhood,
  • “Depriving kids of tech doesn’t work, but simultaneously reducing it and building up other things, like playing outside, does,”
  • Practice restraint.
  • “When you practice stopping, it strengthens those connections in the brain to allow you to stop again next time.”
  • Use tech’s own tools. TikTok has a screen-time management setting that allows users to cap their app usage.
  • Ensure good sleep. Teens are suffering from a sleep deficit.
