Consciousness Isn't a Mystery. It's Matter. - The New York Times - 3 views

  • Every day, it seems, some verifiably intelligent person tells us that we don’t know what consciousness is. The nature of consciousness, they say, is an awesome mystery. It’s the ultimate hard problem. The current Wikipedia entry is typical: Consciousness “is the most mysterious aspect of our lives”; philosophers “have struggled to comprehend the nature of consciousness.”
  • I find this odd because we know exactly what consciousness is — where by “consciousness” I mean what most people mean in this debate: experience of any kind whatever. It’s the most familiar thing there is, whether it’s experience of emotion, pain, understanding what someone is saying, seeing, hearing, touching, tasting or feeling. It is in fact the only thing in the universe whose ultimate intrinsic nature we can claim to know. It is utterly unmysterious.
  • The nature of physical stuff, by contrast, is deeply mysterious, and physics grows stranger by the hour. (Richard Feynman’s remark about quantum theory — “I think I can safely say that nobody understands quantum mechanics” — seems as true as ever.) Or rather, more carefully: The nature of physical stuff is mysterious except insofar as consciousness is itself a form of physical stuff.

  • “We know nothing about the intrinsic quality of physical events,” he wrote, “except when these are mental events that we directly experience.”
  • I think Russell is right: Human conscious experience is wholly a matter of physical goings-on in the body and in particular the brain. But why does he say that we know nothing about the intrinsic quality of physical events except when these are mental events we directly experience? Isn’t he exaggerating? I don’t think so
  • I need to try to reply to those (they’re probably philosophers) who doubt that we really know what conscious experience is.The reply is simple. We know what conscious experience is because the having is the knowing: Having conscious experience is knowing what it is. You don’t have to think about it (it’s really much better not to). You just have to have it. It’s true that people can make all sorts of mistakes about what is going on when they have experience, but none of them threaten the fundamental sense in which we know exactly what experience is just in having it.
  • If someone continues to ask what it is, one good reply (although Wittgenstein disapproved of it) is “you know what it is like from your own case.” Ned Block replies by adapting the response Louis Armstrong reportedly gave to someone who asked him what jazz was: “If you gotta ask, you ain’t never going to know.”
  • So we all know what consciousness is. Once we’re clear on this we can try to go further, for consciousness does of course raise a hard problem. The problem arises from the fact that we accept that consciousness is wholly a matter of physical goings-on, but can’t see how this can be so. We examine the brain in ever greater detail, using increasingly powerful techniques like fMRI, and we observe extraordinarily complex neuroelectrochemical goings-on, but we can’t even begin to understand how these goings-on can be (or give rise to) conscious experiences.
  • 1966 movie “Fantastic Voyage,” or imagine the ultimate brain scanner. Leibniz continued, “Suppose we do: visiting its insides, we will never find anything but parts pushing each other — never anything that could explain a conscious state.”
  • His mistake is to go further, and conclude that physical goings-on can’t possibly be conscious goings-on. Many make the same mistake today — the Very Large Mistake (as Winnie-the-Pooh might put it) of thinking that we know enough about the nature of physical stuff to know that conscious experience can’t be physical. We don’t. We don’t know the intrinsic nature of physical stuff, except — Russell again — insofar as we know it simply through having a conscious experience.
  • We find this idea extremely difficult because we’re so very deeply committed to the belief that we know more about the physical than we do, and (in particular) know enough to know that consciousness can’t be physical. We don’t see that the hard problem is not what consciousness is, it’s what matter is — what the physical is.
  • This point about the limits on what physics can tell us is rock solid, and it arises before we begin to consider any of the deep problems of understanding that arise within physics — problems with “dark matter” or “dark energy,” for example — or with reconciling quantum mechanics and general relativity theory.
  • Those who make the Very Large Mistake (of thinking they know enough about the nature of the physical to know that consciousness can’t be physical) tend to split into two groups. Members of the first group remain unshaken in their belief that consciousness exists, and conclude that there must be some sort of nonphysical stuff: They tend to become “dualists.” Members of the second group, passionately committed to the idea that everything is physical, make the most extraordinary move that has ever been made in the history of human thought. They deny the existence of consciousness: They become “eliminativists.”
  • no one has to react in either of these ways. All they have to do is grasp the fundamental respect in which we don’t know the intrinsic nature of physical stuff in spite of all that physics tells us. In particular, we don’t know anything about the physical that gives us good reason to think that consciousness can’t be wholly physical. It’s worth adding that one can fully accept this even if one is unwilling to agree with Russell that in having conscious experience we thereby know something about the intrinsic nature of physical reality.
  • It’s not the physics picture of matter that’s the problem; it’s the ordinary everyday picture of matter. It’s ironic that the people who are most likely to doubt or deny the existence of consciousness (on the ground that everything is physical, and that consciousness can’t possibly be physical) are also those who are most insistent on the primacy of science, because it is precisely science that makes the key point shine most brightly: the point that there is a fundamental respect in which ultimate intrinsic nature of the stuff of the universe is unknown to us — except insofar as it is consciousness.

What Happened Before the Big Bang? The New Philosophy of Cosmology - Ross Andersen - Te... - 1 views

  • This question of accounting for what we call the "big bang state" -- the search for a physical explanation of it -- is probably the most important question within the philosophy of cosmology, and there are a couple different lines of thought about it.
  • One that's becoming more and more prevalent in the physics community is the idea that the big bang state itself arose out of some previous condition, and that therefore there might be an explanation of it in terms of the previously existing dynamics by which it came about
  • There are other ideas, for instance that maybe there might be special sorts of laws, or special sorts of explanatory principles, that would apply uniquely to the initial state of the universe.
  • ...9 more annotations...
  • One common strategy for thinking about this is to suggest that what we used to call the whole universe is just a small part of everything there is, and that we live in a kind of bubble universe, a small region of something much larger
  • Newton realized there had to be some force holding the moon in its orbit around the earth, to keep it from wandering off, and he knew also there was a force that was pulling the apple down to the earth. And so what suddenly struck him was that those could be one and the same thing, the same force
  • That was a physical discovery, a physical discovery of momentous importance, as important as anything you could ever imagine because it knit together the terrestrial realm and the celestial realm into one common physical picture. It was also a philosophical discovery in the sense that philosophy is interested in the fundamental natures of things.
  • The problem is that quantum mechanics was developed as a mathematical tool. Physicists understood how to use it as a tool for making predictions, but without an agreement or understanding about what it was telling us about the physical world. And that's very clear when you look at any of the foundational discussions. This is what Einstein was upset about; this is what Schrodinger was upset about. Quantum mechanics was merely a calculational technique that was not well understood as a physical theory. Bohr and Heisenberg tried to argue that asking for a clear physical theory was something you shouldn't do anymore. That it was something outmoded. And they were wrong, Bohr and Heisenberg were wrong about that. But the effect of it was to shut down perfectly legitimate physics questions within the physics community for about half a century. And now we're coming out of that
  • The basic philosophical question, going back to Plato, is "What is x?" What is virtue? What is justice? What is matter? What is time? You can ask that about dark energy - what is it? And it's a perfectly good question.
  • right now there are just way too many freely adjustable parameters in physics. Everybody agrees about that. There seem to be many things we call constants of nature that you could imagine setting at different values, and most physicists think there shouldn't be that many, that many of them are related to one another. Physicists think that at the end of the day there should be one complete equation to describe all physics, because any two physical systems interact and physics has to tell them what to do. And physicists generally like to have only a few constants, or parameters of nature. This is what Einstein meant when he famously said he wanted to understand what kind of choices God had --using his metaphor-- how free his choices were in creating the universe, which is just asking how many freely adjustable parameters there are. Physicists tend to prefer theories that reduce that number
  • You have others saying that time is just an illusion, that there isn't really a direction of time, and so forth. I myself think that all of the reasons that lead people to say things like that have very little merit, and that people have just been misled, largely by mistaking the mathematics they use to describe reality for reality itself. If you think that mathematical objects are not in time, and mathematical objects don't change -- which is perfectly true -- and then you're always using mathematical objects to describe the world, you could easily fall into the idea that the world itself doesn't change, because your representations of it don't.
  • physicists for almost a hundred years have been dissuaded from trying to think about fundamental questions. I think most physicists would quite rightly say "I don't have the tools to answer a question like 'what is time?' - I have the tools to solve a differential equation." The asking of fundamental physical questions is just not part of the training of a physicist anymore.
  • The question remains as to how often, after life evolves, you'll have intelligent life capable of making technology. What people haven't seemed to notice is that on earth, of all the billions of species that have evolved, only one has developed intelligence to the level of producing technology. Which means that kind of intelligence is really not very useful. It's not actually, in the general case, of much evolutionary value. We tend to think, because we love to think of ourselves, human beings, as the top of the evolutionary ladder, that the intelligence we have, that makes us human beings, is the thing that all of evolution is striving toward. But what we know is that that's not true. Obviously it doesn't matter that much if you're a beetle, that you be really smart. If it were, evolution would have produced much more intelligent beetles. We have no empirical data to suggest that there's a high probability that evolution on another planet would lead to technological intelligence.

Ask Ethan: Where Is The Line Between Mathematics And Physics? - 0 views

  • What, then, are you supposed to do when the mathematics gets more abstract? What do you do when you get to General Relativity, or Quantum Field Theory, or even more far afield into the speculative realms of cosmic inflation, extra dimensions, grand unified theories, or string theory? The mathematical structures that you build to describe these possibilities simply are what they are; on their own, they won't offer you any physical insights. But if you can pull out either observable quantities, or connections to physically observable quantities, that's when you start crossing over into something that you can test and observe.
  • Now, string theory (or, more accurately, string theories) have their own constraints governing them, as do the forces in our Universe, so it isn't provably clear that there's a one-to-one correspondence between our four-dimensional Universe with gravity, electromagnetism, and the nuclear forces and any version of string theory. It's an interesting conjecture, and it has found some applications to the real world: in the study of quark-gluon plasmas. In that sense, it's more than mathematics: it's physics. But where it strays from physics into pure mathematics is not yet fully determined.
  • If you describe the Universe precisely, and you can make quantitative predictions about it, you're physics. If those predictions turn out to be accurate and reflective of reality, then you're physics that's correct and useful. If those predictions are demonstrably wrong, you're physics that doesn't describe our Universe: you're a failed attempt at a physical theory. But if your equations have no connection at all to the physical Universe, and cannot be related to anything you can ever hope to someday observe or measure, you're firmly in the realm of mathematics; the divorce from physics will then be final. Mathematics is the language we use to describe physics, but not everything mathematical is physically meaningful. The connection, and where it breaks down, can only be determined by looking at the Universe itself.

What Does Quantum Physics Actually Tell Us About the World? - The New York Times - 2 views

  • The physics of atoms and their ever-smaller constituents and cousins is, as Adam Becker reminds us more than once in his new book, “What Is Real?,” “the most successful theory in all of science.” Its predictions are stunningly accurate, and its power to grasp the unseen ultramicroscopic world has brought us modern marvels.
  • But there is a problem: Quantum theory is, in a profound way, weird. It defies our common-sense intuition about what things are and what they can do.
  • Indeed, Heisenberg said that quantum particles “are not as real; they form a world of potentialities or possibilities rather than one of things or facts.”
  • ...19 more annotations...
  • Before he died, Richard Feynman, who understood quantum theory as well as anyone, said, “I still get nervous with it...I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.” The problem is not with using the theory — making calculations, applying it to engineering tasks — but in understanding what it means. What does it tell us about the world?
  • From one point of view, quantum physics is just a set of formalisms, a useful tool kit. Want to make better lasers or transistors or television sets? The Schrödinger equation is your friend. The trouble starts only when you step back and ask whether the entities implied by the equation can really exist. Then you encounter problems that can be described in several familiar ways:
  • Wave-particle duality. Everything there is — all matter and energy, all known forces — behaves sometimes like waves, smooth and continuous, and sometimes like particles, rat-a-tat-tat. Electricity flows through wires, like a fluid, or flies through a vacuum as a volley of individual electrons. Can it be both things at once?
  • The uncertainty principle. Werner Heisenberg famously discovered that when you measure the position (let’s say) of an electron as precisely as you can, you find yourself more and more in the dark about its momentum. And vice versa. You can pin down one or the other but not both.
  • The measurement problem. Most of quantum mechanics deals with probabilities rather than certainties. A particle has a probability of appearing in a certain place. An unstable atom has a probability of decaying at a certain instant. But when a physicist goes into the laboratory and performs an experiment, there is a definite outcome. The act of measurement — observation, by someone or something — becomes an inextricable part of the theory
  • The strange implication is that the reality of the quantum world remains amorphous or indefinite until scientists start measuring
  • Other interpretations rely on “hidden variables” to account for quantities presumed to exist behind the curtain.
  • This is disturbing to philosophers as well as physicists. It led Einstein to say in 1952, “The theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.”
  • “Figuring out what quantum physics is saying about the world has been hard,” Becker says, and this understatement motivates his book, a thorough, illuminating exploration of the most consequential controversy raging in modern science.
  • In a way, the Copenhagen is an anti-interpretation. “It is wrong to think that the task of physics is to find out how nature is,” Bohr said. “Physics concerns what we can say about nature.”
  • Nothing is definite in Bohr’s quantum world until someone observes it. Physics can help us order experience but should not be expected to provide a complete picture of reality. The popular four-word summary of the Copenhagen interpretation is: “Shut up and calculate!”
  • Becker sides with the worriers. He leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories
  • He makes a convincing case that it’s wrong to imagine the Copenhagen interpretation as a single official or even coherent statement. It is, he suggests, a “strange assemblage of claims.
  • An American physicist, David Bohm, devised a radical alternative at midcentury, visualizing “pilot waves” that guide every particle, an attempt to eliminate the wave-particle duality.
  • Competing approaches to quantum foundations are called “interpretations,” and nowadays there are many. The first and still possibly foremost of these is the so-called Copenhagen interpretation.
  • Perhaps the most popular lately — certainly the most talked about — is the “many-worlds interpretation”: Every quantum event is a fork in the road, and one way to escape the difficulties is to imagine, mathematically speaking, that each fork creates a new universe
  • if you think the many-worlds idea is easily dismissed, plenty of physicists will beg to differ. They will tell you that it could explain, for example, why quantum computers (which admittedly don’t yet quite exist) could be so powerful: They would delegate the work to their alter egos in other universes.
  • When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human.
  • If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation...exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

How Depression and Anxiety Affect Your Physical Health - The New York Times - 1 views

  • It’s no surprise that when a person gets a diagnosis of heart disease, cancer or some other life-limiting or life-threatening physical ailment, they become anxious or depressed.
  • But the reverse can also be true: Undue anxiety or depression can foster the development of a serious physical disease, and even impede the ability to withstand or recover from one.
  • The human organism does not recognize the medical profession’s artificial separation of mental and physical ills. Rather, mind and body form a two-way street.
  • ...11 more annotations...
  • What happens inside a person’s head can have damaging effects throughout the body, as well as the other way around. An untreated mental illness can significantly increase the risk of becoming physically ill, and physical disorders may result in behaviors that make mental conditions worse.
  • In studies that tracked how patients with breast cancer fared, for example, Dr. David Spiegel and his colleagues at Stanford University School of Medicine showed decades ago that women whose depression was easing lived longer than those whose depression was getting worse. His research and other studies have clearly shown that “the brain is intimately connected to the body and the body to the brain,”
  • “The body tends to react to mental stress as if it was a physical stress.”
  • Anxiety disorders affect nearly 20 percent of American adults. That means millions are beset by an overabundance of the fight-or-flight response that primes the body for action.
  • “We often talk about depression as a complication of chronic illness,” Dr. Frownfelter wrote in Medpage Today in July. “But what we don’t talk about enough is how depression can lead to chronic disease. Patients with depression may not have the motivation to exercise regularly or cook healthy meals. Many also have trouble getting adequate sleep.”
  • These protective actions stem from the neurotransmitters epinephrine and norepinephrine, which stimulate the sympathetic nervous system and put the body on high alert. But when they are invoked too often and indiscriminately, the chronic overstimulation can result in all manner of physical ills, including digestive symptoms like indigestion, cramps, diarrhea or constipation, and an increased risk of heart attack or stroke.
  • While it’s normal to feel depressed from time to time, more than 6 percent of adults have such persistent feelings of depression that it disrupts personal relationships, interferes with work and play, and impairs their ability to cope with the challenges of daily life
  • “Depression diminishes a person’s capacity to analyze and respond rationally to stress,” Dr. Spiegel said. “They end up on a vicious cycle with limited capacity to get out of a negative mental state.”
  • Although persistent anxiety and depression are highly treatable with medications, cognitive behavioral therapy and talk therapy, without treatment these conditions tend to get worse.
  • When you’re stressed, the brain responds by prompting the release of cortisol, nature’s built-in alarm system. It evolved to help animals facing physical threats by increasing respiration, raising the heart rate and redirecting blood flow from abdominal organs to muscles that assist in confronting or escaping danger.
  • Improving sleep is especially helpful, Dr. Spiegel said, because “it enhances a person’s ability to regulate the stress response system and not get stuck in a mental rut.”

Philosophy isn't dead yet | Raymond Tallis | Comment is free | The Guardian - 1 views

  • Fundamental physics is in a metaphysical mess and needs help. The attempt to reconcile its two big theories, general relativity and quantum mechanics, has stalled for nearly 40 years. Endeavours to unite them, such as string theory, are mathematically ingenious but incomprehensible even to many who work with them. This is well known.
  • A better-kept secret is that at the heart of quantum mechanics is a disturbing paradox – the so-called measurement problem, arising ultimately out of the Uncertainty Principle – which apparently demonstrates that the very measurements that have established and confirmed quantum theory should be impossible. Oxford philosopher of physics David Wallace has argued that this threatens to make quantum mechanics incoherent which can be remedied only by vastly multiplying worlds.
  • there is the failure of physics to accommodate conscious beings. The attempt to fit consciousness into the material world, usually by identifying it with activity in the brain, has failed dismally, if only because there is no way of accounting for the fact that certain nerve impulses are supposed to be conscious (of themselves or of the world) while the overwhelming majority (physically essentially the same) are not. In short, physics does not allow for the strange fact that matter reveals itself to material objects (such as physicists).

  • then there is the mishandling of time. The physicist Lee Smolin's recent book, Time Reborn, links the crisis in physics with its failure to acknowledge the fundamental reality of time. Physics is predisposed to lose time because its mathematical gaze freezes change. Tensed time, the difference between a remembered or regretted past and an anticipated or feared future, is particularly elusive. This worried Einstein: in a famous conversation, he mourned the fact that the present tense, "now", lay "just outside of the realm of science".
  • Recent attempts to explain how the universe came out of nothing, which rely on questionable notions such as spontaneous fluctuations in a quantum vacuum, the notion of gravity as negative energy, and the inexplicable free gift of the laws of nature waiting in the wings for the moment of creation, reveal conceptual confusion beneath mathematical sophistication. They demonstrate the urgent need for a radical re-examination of the invisible frameworks within which scientific investigations are conducted.
  • we should reflect on how a scientific image of the world that relies on up to 10 dimensions of space and rests on ideas, such as fundamental particles, that have neither identity nor location, connects with our everyday experience. This should open up larger questions, such as the extent to which mathematical portraits capture the reality of our world – and what we mean by "reality".

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.

  • 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.

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,

  • 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.

  • 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

  • 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.

  • 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.

  • 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;

  • 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

  • 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.

  • 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.

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.

  • 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.

  • 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.”

  • Around 100 years ago, quantum mechanics was a purely theoretical topic, only developed to understand certain properties of atoms
  • But today, quantum mechanics is the basis of our use of all semiconductors in computers and mobile phones
  • Despite these direct and indirect benefits, most theoretical physicists have a very different motive for their work. They simply want to improve humanity’s understanding of the universe. While this might not immediately impact everyone’s lives, I believe it is just as important a reason for pursuing fundamental research
  • It somehow seems that every new level of understanding we achieve comes in tandem with new, more fundamental questions. It is never enough to know what we now know. We always want to continue looking behind newly arising curtains. In that respect, I consider fundamental physics a basic part of human culture.

How Einstein Challenged Newtonian Physics - 0 views

  • Any discussion of Einstein should begin with what is probably his single greatest contribution to physics—the theory of relativity.
  • Between the late 1600s and the beginning of the 20th century, the field of physics was dominated by the ideas of Isaac Newton. The Newtonian laws of motion and gravitation had, up to that point in time, been the most successful scientific theory in all of history.
  • Newton’s ideas were, of course, challenged from time to time during those two centuries, but these ideas always seemed to hold up
  • ...9 more annotations...
  • There were many new phenomena that were discovered and that came to be understood in the centuries that followed Newton’s era. Take electricity and magnetism, for example. Until the 19th century, we didn’t really know what electricity or magnetism were, or how they worked. Isaac Newton certainly didn’t have a clue.
  • To many physicists around the turn of the 20th century, the state of physics seemed very settled. The Newtonian worldview had been very successful, and for a very long time.
  • In 1905, however, a revolution in physics did come. And perhaps even more surprising than the revolution itself was where that revolution came from. In 1905, Albert Einstein was not working as a professor at some prestigious university. He was not famous, or even well-known among other physicists.
  • Things didn’t stay this way for long, however. In 1905, Einstein wrote not one or two, but four absolutely groundbreaking papers. Any one of these four papers would have made him a star within the field of physics, and would have certainly secured him a position of prominence in the history of science.
  • It seems that having so many breakthroughs of this magnitude in such a short period of time had never happened before, and has never happened since. In the first of Einstein’s 1905 papers, he proposed that light doesn’t only behave like a wave, but that it is also made up of individual pieces or particles.
  • But Einstein’s paper provided concrete empirical evidence that atoms were, in fact, real and tangible objects. He was even able to use these arguments to make a pretty good estimate for the size and mass of atoms and molecules. It was a huge step forward.
  • The equations that physicists use to describe the propagation of light waves—what are known as Maxwell’s equations—predict that light should move through space at a speed of about 670 million miles per hour. And more interestingly, these equations don’t make any reference to any medium that the light waves propagate through.
  • Although no experiment had ever detected this aether, they argued that it must fill virtually all of space. After all, they argued, the light from a distant star could only reach us if there was a continuous path filled with aether, extending all the way from the star to us.
  • ventually, though, physicists discovered that there was no aether. It would be Einstein who would come up with an equation to explain this conundrum.

The psychology of hate: How we deny human beings their humanity - Salon.com - 0 views

  • The cross-cultural psychologist Gustav Jahoda catalogued how Europeans since the time of the ancient Greeks viewed those living in relatively primitive cultures as lacking a mind in one of two ways: either lacking self-control and emotions, like an animal, or lacking reason and intellect, like a child. So foreign in appearance, language, and manner, “they” did not simply become other people, they became lesser people. More specifically, they were seen as having lesser minds, diminished capacities to either reason or feel.
  • In the early 1990ss, California State Police commonly referred to crimes involving young black men as NHI—No Humans Involved.
  • The essence of dehumanization is, therefore, failing to recognize the fully human mind of another person. Those who fight against dehumanization typically deal with extreme cases that can make it seem like a relatively rare phenomenon. It is not. Subtle versions are all around us.

  • Even doctors—those whose business is to treat others humanely— can remain disengaged from the minds of their patients, particularly when those patients are easily seen as different from the doctors themselves. Until the early 1990s, for instance, it was routine practice for infants to undergo surgery without anesthesia. Why? Because at the time, doctors did not believe that infants were able to experience pain, a fundamental capacity of the human mind.
  • Your sixth sense functions only when you engage it. When you do not, you may fail to recognize a fully human mind that is right before your eyes.
  • Although it is indeed true that the ability to read the minds of others exists along a spectrum with stable individual differences, I believe that the more useful knowledge comes from understanding the moment-to-moment, situational influences that can lead even the most social person—yes, even you and me—to treat others as mindless animals or objects.
  • None of the cases described in this chapter so far involve people with chronic and stable personality disorders. Instead, they all come from predictable contexts in which people’s sixth sense remained disengaged for one fundamental reason: distance.
  • For psychologists, distance is not just physical space. It is also psychological space, the degree to which you feel closely connected to someone else. You are describing psychological distance when you say that you feel “distant” from your spouse, “out of touch” with your kids’ lives, “worlds apart” from a neighbor’s politics, or “separated” from your employees. You don’t mean that you are physically distant from other people; you mean that you feel psychologically distant from them in some way
  • Distance keeps your sixth sense disengaged for at least two reasons. First, your ability to understand the minds of others can be triggered by your physical senses. When you’re too far away in physical space, those triggers do not get pulled. Second, your ability to understand the minds of others is also engaged by your cognitive inferences. Too far away in psychological space—too different, too foreign, too other—and those triggers, again, do not get pulled
  • This three-part chain—sharing attention, imitating action, and imitation creating experience—shows one way in which your sixth sense works through your physical senses. More important, it also shows how your sixth sense could remain disengaged, leaving you disconnected from the minds of others. Close your eyes, look away, plug your ears, stand too far away to see or hear, or simply focus your attention elsewhere, and your sixth sense may not be triggered.
  • Interviews with U.S. soldiers in World War II found that only 15 to 20 percent were able to discharge their weapons at the enemy in close firefights. Even when they did shoot, soldiers found it hard to hit their human targets. In the U.S. Civil War, muskets were capable of hitting a pie plate at 70 yards and soldiers could typically reload anywhere from 4 to 5 times per minute. Theoretically, a regiment of 200 soldiers firing at a wall of enemy soldiers 100 feet wide should be able to kill 120 on the first volley. And yet the kill rate during the Civil War was closer to 1 to 2 men per minute, with the average distance of engagement being only 30 yards.
  • Modern armies now know that they have to overcome these empathic urges, so soldiers undergo relentless training that desensitizes them to close combat, so that they can do their jobs. Modern technology also allows armies to kill more easily because it enables killing at such a great physical distance. Much of the killing by U.S. soldiers now comes through the hands of drone pilots watching a screen from a trailer in Nevada, with their sixth sense almost completely disengaged.
  • Other people obviously do not need to be standing right in front of you for you to imagine what they are thinking or feeling or planning. You can simply close your eyes and imagine it.
  • The MPFC and a handful of other brain regions undergird the inferential component of your sixth sense. When this network of brain regions is engaged, you are thinking about others’ minds. Failing to engage this region when thinking about other people is then a solid indication that you’re overlooking their minds.
  • Research confirms that the MPFC is engaged more when you’re thinking about yourself, your close friends and family, and others who have beliefs similar to your own. It is activated when you care enough about others to care what they are thinking, and not when you are indifferent to others
  • As people become more and more different from us, or more distant from our immediate social networks, they become less and less likely to engage our MPFC. When we don’t engage this region, others appear relatively mindless, something less than fully human.
  • The mistake that can arise when you fail to engage with the minds of others is that you may come to think of them as relatively mindless. That is, you may come to think that these others have less going on between their ears than, say, you do.
  • It’s not only free will that other minds might seem to lack. This lesser minds effect has many manifestations, including what appears to be a universal tendency to assume that others’ minds are less sophisticated and more superficial than one’s own. Members of distant out-groups, ranging from terrorists to poor hurricane victims to political opponents, are also rated as less able to experience complicated emotions, such as shame, pride, embarassment, and guilt than close members of one’s own group.

  • Thus science is not a continuous or cumulative endeavor: when a paradigm shift occurs there is a revolution similar to a political revolution, with fundamental and pervasive changes in method and understanding. Each successive vision about the nature of the universe makes the past vision obsolete; predictions, though more precise, remain similar to the predictions of the past paradigm in their general orientation, but the new explanations do not accommodate the old
  • In a sense, we have circled back to the ancient and medieval practice of separating scientific theory from physical reality; both medieval scientists and Kuhn would agree that no theory corresponds to reality and therefore any number of theories might equally well explain a natural phenomenon. [36] Neither twentieth-century atomic theorists nor medieval astronomers are able to claim that their theories accurately describe physical phenomena. The inability to return to scientific realism suggests a tripartite division of the history of science, with a period of scientific realism fitting between two periods in which there is no insistence that theory correspond to reality. Although both scientific realism and the evolutionary idea of scientific progress appeal to common sense, both existed for only a few hundred years.

Departing Leader of CERN Ponders Uncertainties That Lie Ahead - 0 views

  • Dr. Heuer, born in Bad Boll in southern Germany in 1948, has spent his career in the trenches of particle physics, in which scientists emulate 3-year-olds by smashing bits of matter together to see what comes out.
  • He had an opportunity to put that philosophy to the test early in his term at CERN, when physicists reported in a seminar there that they had measured subatomic particles known as neutrinos streaming from Geneva to their detector in Italy faster than the speed of light, contrary to the laws of physics then known.
  • The neutrino controversy helped set a sort of dubious stage for the main event in particle physics so far this century: the Higgs boson.
  • ...2 more annotations...
  • The Higgs boson completed the Standard Model, a suite of equations that agrees with all the experiments that have been done on earth. But that model is not the end of physics. It does not explain dark matter or dark energy, the two major constituents of the cosmos, for example, or why the universe is made of matter instead of antimatter.
  • For decades, theorists have flirted with a concept called supersymmetry that would address some of these issues and produce a bounty of new particles for CERN’s collider.

The Myth of Wealthy Men and Beautiful Women - The Atlantic - 1 views

  • Experiments that don’t rely on self-reporting regularly show that physical attractiveness is exquisitely, at times incomparably, important to both men and women. Status (however you want to measure it: income, formal education, et cetera) is often not far behind
  • In real-life dating studies, which get closer to genuine intentions, physical attractiveness and earning potential strongly predict romantic attraction.
  • when it comes to beauty and income, more is almost always seen as better. On these “consensually-ranked” traits, people seem to aspire to partners who rank more highly than themselves. They don’t want a match so much as a jackpot.
  • ...8 more annotations...
  • McClintock found that outside of ailing tycoons and Donald Trump, in the practical world it basically doesn’t exist. Where it does, it doesn’t last. The dominant force in mating is matching.
  • What appears to be an exchange of beauty for socioeconomic status is often actually not an exchange, McClintock wrote, but a series of matched virtues
  • Economically successful women partner with economically successful men, and physically attractive women partner with physically attractive men.
  • Because people of high socioeconomic status are, on average, rated as more physically attractive than people of lower status, many correlations between one partner's appearance and the other partner's status are spurious and misconstrued.
  • “Women spend a lot more time trying to look good than men do,” McClintock said. “That creates a lot of mess in this data. If you don’t take that into account then you actually see there’s a lot of these guys who are partnered with women who are better looking than them, which is just because, on average, women are better looking. Men are partnering 'up' in attractiveness.
  • And men earn more than women—we’ve got that 70-percent wage gap—so women marry 'up' in income. You’ve got to take these things into account before concluding that women are trading beauty for money.”
  • “It would be very hard to separate out class and attractiveness,” McClintock said, “because they’re just so fundamentally linked. I can’t control for that—but I don’t see how anybody could.”
  • “Controlling for both partners’ physical attractiveness may not eliminate the relationship between female beauty and male status,” McClintock wrote, “but it should at least reduce this relationship substantially.”

Is our world a simulation? Why some scientists say it's more likely than not | Technolo... - 3 views

  • Musk is just one of the people in Silicon Valley to take a keen interest in the “simulation hypothesis”, which argues that what we experience as reality is actually a giant computer simulation created by a more sophisticated intelligence
  • Oxford University’s Nick Bostrom in 2003 (although the idea dates back as far as the 17th-century philosopher René Descartes). In a paper titled “Are You Living In a Simulation?”, Bostrom suggested that members of an advanced “posthuman” civilization with vast computing power might choose to run simulations of their ancestors in the universe.
  • If we believe that there is nothing supernatural about what causes consciousness and it’s merely the product of a very complex architecture in the human brain, we’ll be able to reproduce it. “Soon there will be nothing technical standing in the way to making machines that have their own consciousness,

  • At the same time, videogames are becoming more and more sophisticated and in the future we’ll be able to have simulations of conscious entities inside them.
  • “Forty years ago we had Pong – two rectangles and a dot. That’s where we were. Now 40 years later, we have photorealistic, 3D simulations with millions of people playing simultaneously and it’s getting better every year. And soon we’ll have virtual reality, we’ll have augmented reality,” said Musk. “If you assume any rate of improvement at all, then the games will become indistinguishable from reality.”
  • “If one progresses at the current rate of technology a few decades into the future, very quickly we will be a society where there are artificial entities living in simulations that are much more abundant than human beings.
  • If there are many more simulated minds than organic ones, then the chances of us being among the real minds starts to look more and more unlikely. As Terrile puts it: “If in the future there are more digital people living in simulated environments than there are today, then what is to say we are not part of that already?”
  • Reasons to believe that the universe is a simulation include the fact that it behaves mathematically and is broken up into pieces (subatomic particles) like a pixelated video game. “Even things that we think of as continuous – time, energy, space, volume – all have a finite limit to their size. If that’s the case, then our universe is both computable and finite. Those properties allow the universe to be simulated,” Terrile said
  • “Is it logically possible that we are in a simulation? Yes. Are we probably in a simulation? I would say no,” said Max Tegmark, a professor of physics at MIT.
  • “In order to make the argument in the first place, we need to know what the fundamental laws of physics are where the simulations are being made. And if we are in a simulation then we have no clue what the laws of physics are. What I teach at MIT would be the simulated laws of physics,”
  • Terrile believes that recognizing that we are probably living in a simulation is as game-changing as Copernicus realizing that the Earth was not the center of the universe. “It was such a profound idea that it wasn’t even thought of as an assumption,”
  • That we might be in a simulation is, Terrile argues, a simpler explanation for our existence than the idea that we are the first generation to rise up from primordial ooze and evolve into molecules, biology and eventually intelligence and self-awareness. The simulation hypothesis also accounts for peculiarities in quantum mechanics, particularly the measurement problem, whereby things only become defined when they are observed.
  • “For decades it’s been a problem. Scientists have bent over backwards to eliminate the idea that we need a conscious observer. Maybe the real solution is you do need a conscious entity like a conscious player of a video game,
  • How can the hypothesis be put to the test
  • scientists can look for hallmarks of simulation. “Suppose someone is simulating our universe – it would be very tempting to cut corners in ways that makes the simulation cheaper to run. You could look for evidence of that in an experiment,” said Tegmark
  • First, it provides a scientific basis for some kind of afterlife or larger domain of reality above our world. “You don’t need a miracle, faith or anything special to believe it. It comes naturally out of the laws of physics,”
  • it means we will soon have the same ability to create our own simulations. “We will have the power of mind and matter to be able to create whatever we want and occupy those worlds.”

Why Do We Spend So Much Time Teaching Historical Physics? - 0 views

  •  
    One of the two classes I'm teaching this term is our sophomore-level "modern physics" class, which richly deserves its scare quotes. "Modern physics" in an educational context means, essentially, "Physics from 1900-1950." It's a brief introduction to Special Relativity, followed by some introductory quantum physics, and a smattering of applications (solid state, nuclear) as time permits.

Opinion | The Social Sciences' 'Physics Envy' - The New York Times - 0 views

  • Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,” “experiment,” “law”) evocative of physics and chemistry.
  • Many social scientists contend that science has a method, and if you want to be scientific, you should adopt it. The method requires you to devise a theoretical model, deduce a testable hypothesis from the model and then test the hypothesis against the world. If the hypothesis is confirmed, the theoretical model holds; if the hypothesis is not confirmed, the theoretical model does not hold. If your discipline does not operate by this method — known as hypothetico-deductivism — then in the minds of many, it’s not scientific.
  • it’s not even a good description of how the “hard” sciences work. It’s a high school textbook version of science, with everything messy and chaotic about scientific inquiry safely ignored.

  • For the sake of everyone who stands to gain from a better knowledge of politics, economics and society, the social sciences need to overcome their inferiority complex, reject hypothetico-deductivism and embrace the fact that they are mature disciplines with no need to emulate other sciences.
  • Or consider the famous “impossibility theorem,” developed by the economist Kenneth Arrow, which shows that no single voting system can simultaneously satisfy several important principles of fairness. There is no need to test this model with data — in fact, there is no way to test it — and yet the result offers policy makers a powerful lesson: there are unavoidable trade-offs in the design of voting systems.
  • Unfortunately, the belief that every theory must have its empirical support (and vice versa) now constrains the kinds of social science projects that are undertaken, alters the trajectory of academic careers and drives graduate training. Rather than attempt to imitate the hard sciences, social scientists would be better off doing what they do best: thinking deeply about what prompts human beings to behave the way they do.
  • theories are like maps: the test of a map lies not in arbitrarily checking random points but in whether people find it useful to get somewhere.
  • Likewise, the analysis of empirical data can be valuable even in the absence of a grand theoretical model. Did the welfare reform championed by Bill Clinton in the 1990s reduce poverty? Are teenage employees adversely affected by increases in the minimum wage?
  • Answering such questions about the effects of public policies does not require sweeping theoretical claims, just careful attention to the data.
  • theoretical models can be of great value even if they are never supported by empirical testing. In the 1950s, for instance, the economist Anthony Downs offered an elegant explanation for why rival political parties might adopt identical platforms during an election campaign. His model relied on the same strategic logic that explains why two competing gas stations or fast-food restaurants locate across the street from each other — if you don’t move to a central location but your opponent does, your opponent will nab those voters (customers). The best move is for competitors to mimic each other. This framework has proven useful to generations of political scientists even though Mr. Downs did not empirically test it and despite the fact that its main prediction, that candidates will take identical positions in elections, is clearly false. The model offered insight into why candidates move toward the center in competitive elections

The Theory That Explains the Structure of the Internet - The Atlantic - 1 views

  • A paper posted online last month has reignited a debate about one of the oldest, most startling claims in the modern era of network science: the proposition that most complex networks in the real world—from the World Wide Web to interacting proteins in a cell—are “scale-free.” Roughly speaking, that means that a few of their nodes should have many more connections than others, following a mathematical formula called a power law, so that there’s no one scale that characterizes the network.
  • Purely random networks do not obey power laws, so when the early proponents of the scale-free paradigm started seeing power laws in real-world networks in the late 1990s, they viewed them as evidence of a universal organizing principle underlying the formation of these diverse networks. The architecture of scale-freeness, researchers argued, could provide insight into fundamental questions such as how likely a virus is to cause an epidemic, or how easily hackers can disable a network.
  • Amazingly simple and far-reaching natural laws govern the structure and evolution of all the complex networks that surround us,” wrote Barabási (who is now at Northeastern University in Boston) in Linked. He later added: “Uncovering and explaining these laws has been a fascinating roller-coaster ride during which we have learned more about our complex, interconnected world than was known in the last hundred years.”
  • ...5 more annotations...
  • “These results undermine the universality of scale-free networks and reveal that real-world networks exhibit a rich structural diversity that will likely require new ideas and mechanisms to explain,” wrote the study’s authors, Anna Broido and Aaron Clauset of the University of Colorado at Boulder.
  • Network scientists agree, by and large, that the paper’s analysis is statistically sound. But when it comes to interpreting its findings, the paper seems to be functioning like a Rorschach test, in which both proponents and critics of the scale-free paradigm see what they already believed to be true. Much of the discussion has played out in vigorous Twitter debates.
  • The scale-free paradigm in networks emerged at a historical moment when power laws had taken on an outsize role in statistical physics. In the 1960s and 1970s, they had played a key part in universal laws that underlie phase transitions in a wide range of physical systems, a finding that earned Kenneth Wilson the 1982 Nobel Prize in physics. Soon after, power laws formed the core of two other paradigms that swept across the statistical-physics world: fractals, and a theory about organization in nature called self-organized criticality.
  • From the beginning, though, the scale-free paradigm also attracted pushback. Critics pointed out that preferential attachment is far from the only mechanism that can give rise to power laws, and that networks with the same power law can have very different topologies. Some network scientists and domain experts cast doubt on the scale-freeness of specific networks such as power grids, metabolic networks, and the physical internet.
  • If you were to observe 1,000 falling objects instead of just a rock and a feather, Clauset says, a clear picture would emerge of how both gravity and air resistance work. But his and Broido’s analysis of nearly 1,000 networks has yielded no similar clarity. “It is reasonable to believe a fundamental phenomenon would require less customized detective work” than Barabási is calling for, Clauset wrote on Twitter.

Quantum math makes human irrationality more sensible | Science News - 0 views

  • People often say that quantum physics is weird because it doesn’t seem rational. But of course, if you think about it, quantum physics is actually perfectly rational, if you understand the math. It’s people who typically seem irrational.
  • In fact, some psychologists have spent their careers making fun of people for irrational choices when presented with artificial situations amenable to statistical analysis. Making allowances for sometimes shaky methodology, there really are cases where people make choices that don’t seem to make much sense.
  • In 1929, Bohr noted that quantum physics refuted the view that analyzing brain processes could “reveal a causal chain that formed a unique representation of the emotional mental experience.” But in quantum physics, Bohr emphasized, an observer inevitably interacted with whatever was being observed, so “any attempt to acquire a knowledge of such [mental] processes involves a fundamentally uncontrollable interference with their course.”

Noam Chomsky on Where Artificial Intelligence Went Wrong - Yarden Katz - The Atlantic - 0 views

  • If you take a look at the progress of science, the sciences are kind of a continuum, but they're broken up into fields. The greatest progress is in the sciences that study the simplest systems. So take, say physics -- greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.
  • If a molecule is too big, you give it to the chemists. The chemists, for them, if the molecule is too big or the system gets too big, you give it to the biologists. And if it gets too big for them, they give it to the psychologists, and finally it ends up in the hands of the literary critic, and so on.
  • neuroscience for the last couple hundred years has been on the wrong track. There's a fairly recent book by a very good cognitive neuroscientist, Randy Gallistel and King, arguing -- in my view, plausibly -- that neuroscience developed kind of enthralled to associationism and related views of the way humans and animals work. And as a result they've been looking for things that have the properties of associationist psychology.

  • in general what he argues is that if you take a look at animal cognition, human too, it's computational systems. Therefore, you want to look the units of computation. Think about a Turing machine, say, which is the simplest form of computation, you have to find units that have properties like "read", "write" and "address." That's the minimal computational unit, so you got to look in the brain for those. You're never going to find them if you look for strengthening of synaptic connections or field properties, and so on. You've got to start by looking for what's there and what's working and you see that from Marr's highest level.
  • it's basically in the spirit of Marr's analysis. So when you're studying vision, he argues, you first ask what kind of computational tasks is the visual system carrying out. And then you look for an algorithm that might carry out those computations and finally you search for mechanisms of the kind that would make the algorithm work. Otherwise, you may never find anything.
  • "Good Old Fashioned AI," as it's labeled now, made strong use of formalisms in the tradition of Gottlob Frege and Bertrand Russell, mathematical logic for example, or derivatives of it, like nonmonotonic reasoning and so on. It's interesting from a history of science perspective that even very recently, these approaches have been almost wiped out from the mainstream and have been largely replaced -- in the field that calls itself AI now -- by probabilistic and statistical models. My question is, what do you think explains that shift and is it a step in the right direction?
  • AI and robotics got to the point where you could actually do things that were useful, so it turned to the practical applications and somewhat, maybe not abandoned, but put to the side, the more fundamental scientific questions, just caught up in the success of the technology and achieving specific goals.
  • The approximating unanalyzed data kind is sort of a new approach, not totally, there's things like it in the past. It's basically a new approach that has been accelerated by the existence of massive memories, very rapid processing, which enables you to do things like this that you couldn't have done by hand. But I think, myself, that it is leading subjects like computational cognitive science into a direction of maybe some practical applicability... ..in engineering? Chomsky: ...But away from understanding.
  • I was very skeptical about the original work. I thought it was first of all way too optimistic, it was assuming you could achieve things that required real understanding of systems that were barely understood, and you just can't get to that understanding by throwing a complicated machine at it.
  • if success is defined as getting a fair approximation to a mass of chaotic unanalyzed data, then it's way better to do it this way than to do it the way the physicists do, you know, no thought experiments about frictionless planes and so on and so forth. But you won't get the kind of understanding that the sciences have always been aimed at -- what you'll get at is an approximation to what's happening.
  • Suppose you want to predict tomorrow's weather. One way to do it is okay I'll get my statistical priors, if you like, there's a high probability that tomorrow's weather here will be the same as it was yesterday in Cleveland, so I'll stick that in, and where the sun is will have some effect, so I'll stick that in, and you get a bunch of assumptions like that, you run the experiment, you look at it over and over again, you correct it by Bayesian methods, you get better priors. You get a pretty good approximation of what tomorrow's weather is going to be. That's not what meteorologists do -- they want to understand how it's working. And these are just two different concepts of what success means, of what achievement is.
  • if you get more and more data, and better and better statistics, you can get a better and better approximation to some immense corpus of text, like everything in The Wall Street Journal archives -- but you learn nothing about the language.
  • the right approach, is to try to see if you can understand what the fundamental principles are that deal with the core properties, and recognize that in the actual usage, there's going to be a thousand other variables intervening -- kind of like what's happening outside the window, and you'll sort of tack those on later on if you want better approximations, that's a different approach.
  • take a concrete example of a new field in neuroscience, called Connectomics, where the goal is to find the wiring diagram of very complex organisms, find the connectivity of all the neurons in say human cerebral cortex, or mouse cortex. This approach was criticized by Sidney Brenner, who in many ways is [historically] one of the originators of the approach. Advocates of this field don't stop to ask if the wiring diagram is the right level of abstraction -- maybe it's no
  • if you went to MIT in the 1960s, or now, it's completely different. No matter what engineering field you're in, you learn the same basic science and mathematics. And then maybe you learn a little bit about how to apply it. But that's a very different approach. And it resulted maybe from the fact that really for the first time in history, the basic sciences, like physics, had something really to tell engineers. And besides, technologies began to change very fast, so not very much point in learning the technologies of today if it's going to be different 10 years from now. So you have to learn the fundamental science that's going to be applicable to whatever comes along next. And the same thing pretty much happened in medicine.
  • that's the kind of transition from something like an art, that you learn how to practice -- an analog would be trying to match some data that you don't understand, in some fashion, maybe building something that will work -- to science, what happened in the modern period, roughly Galilean science.
  • it turns out that there actually are neural circuits which are reacting to particular kinds of rhythm, which happen to show up in language, like syllable length and so on. And there's some evidence that that's one of the first things that the infant brain is seeking -- rhythmic structures. And going back to Gallistel and Marr, its got some computational system inside which is saying "okay, here's what I do with these things" and say, by nine months, the typical infant has rejected -- eliminated from its repertoire -- the phonetic distinctions that aren't used in its own language.
  • people like Shimon Ullman discovered some pretty remarkable things like the rigidity principle. You're not going to find that by statistical analysis of data. But he did find it by carefully designed experiments. Then you look for the neurophysiology, and see if you can find something there that carries out these computations. I think it's the same in language, the same in studying our arithmetical capacity, planning, almost anything you look at. Just trying to deal with the unanalyzed chaotic data is unlikely to get you anywhere, just like as it wouldn't have gotten Galileo anywhere.
  • with regard to cognitive science, we're kind of pre-Galilean, just beginning to open up the subject
  • You can invent a world -- I don't think it's our world -- but you can invent a world in which nothing happens except random changes in objects and selection on the basis of external forces. I don't think that's the way our world works, I don't think it's the way any biologist thinks it is. There are all kind of ways in which natural law imposes channels within which selection can take place, and some things can happen and other things don't happen. Plenty of things that go on in the biology in organisms aren't like this. So take the first step, meiosis. Why do cells split into spheres and not cubes? It's not random mutation and natural selection; it's a law of physics. There's no reason to think that laws of physics stop there, they work all the way through. Well, they constrain the biology, sure. Chomsky: Okay, well then it's not just random mutation and selection. It's random mutation, selection, and everything that matters, like laws of physics.
  • What I think is valuable is the history of science. I think we learn a lot of things from the history of science that can be very valuable to the emerging sciences. Particularly when we realize that in say, the emerging cognitive sciences, we really are in a kind of pre-Galilean stage. We don't know wh
