Will the Quantum Nature of Gravity Finally Be Measured? - The Atlantic - 0 views

  • In 1935, when both quantum mechanics and Albert Einstein’s general theory of relativity were young, a little-known Soviet physicist named Matvei Bronstein, just 28 himself, made the first detailed study of the problem of reconciling the two in a quantum theory of gravity. This “possible theory of the world as a whole,” as Bronstein called it, would supplant Einstein’s classical description of gravity, which casts it as curves in the space-time continuum, and rewrite it in the same quantum language as the rest of physics.
  • His words were prophetic. Eighty-three years later, physicists are still trying to understand how space-time curvature emerges on macroscopic scales from a more fundamental, presumably quantum picture of gravity; it’s arguably the deepest question in physics.
  • The search for the full theory of quantum gravity has been stymied by the fact that gravity’s quantum properties never seem to manifest in actual experience. Physicists never get to see how Einstein’s description of the smooth space-time continuum, or Bronstein’s quantum approximation of it when it’s weakly curved, goes wrong.

  • Not only that, but the universe appears to be governed by a kind of cosmic censorship: Regions of extreme gravity—where space-time curves so sharply that Einstein’s equations malfunction and the true, quantum nature of gravity and space-time must be revealed—always hide behind the horizons of black holes.
  • Dyson, who helped develop quantum electrodynamics (the theory of interactions between matter and light) and is professor emeritus at the Institute for Advanced Study in Princeton, New Jersey, where he overlapped with Einstein, disagrees with the argument that quantum gravity is needed to describe the unreachable interiors of black holes. And he wonders whether detecting the hypothetical graviton might be impossible, even in principle. In that case, he argues, quantum gravity is metaphysical, rather than physics.
  • The ability to detect the “grin” of quantum gravity would seem to refute Dyson’s argument. It would also kill the gravitational decoherence theory, by showing that gravity and space-time do maintain quantum superpositions.
  • If gravity is a quantum interaction, then the answer is: It depends. Each component of the blue diamond’s superposition will experience a stronger or weaker gravitational attraction to the red diamond, depending on whether the latter is in the branch of its superposition that’s closer or farther away. And the gravity felt by each component of the red diamond’s superposition similarly depends on where the blue diamond is.

How Isaac Newton Changed the World | Live Science - 0 views

  • To the probable dismay of some befuddled calculus and physics students the world over, Isaac Newton didn't just live, he grew up and lived long enough to become the single-most influential scientist of the 17th-century.
  • Newton's wide range of discoveries, from his theories of optics to his groundbreaking work on the laws of motion and gravity, formed the basis for modern physics.
  • The true genius of his work, experts think, is how he ultimately took those theories and applied them to the universe at large, explaining the motions of the Sun and planets in a way that had never been done before.

How Does Science Really Work? | The New Yorker - 1 views

  • I wanted to be a scientist. So why did I find the actual work of science so boring? In college science courses, I had occasional bursts of mind-expanding insight. For the most part, though, I was tortured by drudgery.
  • I’d found that science was two-faced: simultaneously thrilling and tedious, all-encompassing and narrow. And yet this was clearly an asset, not a flaw. Something about that combination had changed the world completely.
  • “Science is an alien thought form,” he writes; that’s why so many civilizations rose and fell before it was invented. In his view, we downplay its weirdness, perhaps because its success is so fundamental to our continued existence.
  • ...50 more annotations...
  • In school, one learns about “the scientific method”—usually a straightforward set of steps, along the lines of “ask a question, propose a hypothesis, perform an experiment, analyze the results.”
  • That method works in the classroom, where students are basically told what questions to pursue. But real scientists must come up with their own questions, finding new routes through a much vaster landscape.
  • Since science began, there has been disagreement about how those routes are charted. Two twentieth-century philosophers of science, Karl Popper and Thomas Kuhn, are widely held to have offered the best accounts of this process.
  • For Popper, Strevens writes, “scientific inquiry is essentially a process of disproof, and scientists are the disprovers, the debunkers, the destroyers.” Kuhn’s scientists, by contrast, are faddish true believers who promulgate received wisdom until they are forced to attempt a “paradigm shift”—a painful rethinking of their basic assumptions.
  • Working scientists tend to prefer Popper to Kuhn. But Strevens thinks that both theorists failed to capture what makes science historically distinctive and singularly effective.
  • Sometimes they seek to falsify theories, sometimes to prove them; sometimes they’re informed by preëxisting or contextual views, and at other times they try to rule narrowly, based on t
  • Why do scientists agree to this scheme? Why do some of the world’s most intelligent people sign on for a lifetime of pipetting?
  • Strevens thinks that they do it because they have no choice. They are constrained by a central regulation that governs science, which he calls the “iron rule of explanation.” The rule is simple: it tells scientists that, “if they are to participate in the scientific enterprise, they must uncover or generate new evidence to argue with”; from there, they must “conduct all disputes with reference to empirical evidence alone.”
  • , it is “the key to science’s success,” because it “channels hope, anger, envy, ambition, resentment—all the fires fuming in the human heart—to one end: the production of empirical evidence.”
  • Strevens arrives at the idea of the iron rule in a Popperian way: by disproving the other theories about how scientific knowledge is created.
  • The problem isn’t that Popper and Kuhn are completely wrong. It’s that scientists, as a group, don’t pursue any single intellectual strategy consistently.
  • Exploring a number of case studies—including the controversies over continental drift, spontaneous generation, and the theory of relativity—Strevens shows scientists exerting themselves intellectually in a variety of ways, as smart, ambitious people usually do.
  • “Science is boring,” Strevens writes. “Readers of popular science see the 1 percent: the intriguing phenomena, the provocative theories, the dramatic experimental refutations or verifications.” But, he says,behind these achievements . . . are long hours, days, months of tedious laboratory labor. The single greatest obstacle to successful science is the difficulty of persuading brilliant minds to give up the intellectual pleasures of continual speculation and debate, theorizing and arguing, and to turn instead to a life consisting almost entirely of the production of experimental data.
  • Ultimately, in fact, it was good that the geologists had a “splendid variety” of somewhat arbitrary opinions: progress in science requires partisans, because only they have “the motivation to perform years or even decades of necessary experimental work.” It’s just that these partisans must channel their energies into empirical observation. The iron rule, Strevens writes, “has a valuable by-product, and that by-product is data.”
  • Science is often described as “self-correcting”: it’s said that bad data and wrong conclusions are rooted out by other scientists, who present contrary findings. But Strevens thinks that the iron rule is often more important than overt correction.
  • Eddington was never really refuted. Other astronomers, driven by the iron rule, were already planning their own studies, and “the great preponderance of the resulting measurements fit Einsteinian physics better than Newtonian physics.” It’s partly by generating data on such a vast scale, Strevens argues, that the iron rule can power science’s knowledge machine: “Opinions converge not because bad data is corrected but because it is swamped.”
  • Why did the iron rule emerge when it did? Strevens takes us back to the Thirty Years’ War, which concluded with the Peace of Westphalia, in 1648. The war weakened religious loyalties and strengthened national ones.
  • Two regimes arose: in the spiritual realm, the will of God held sway, while in the civic one the decrees of the state were paramount. As Isaac Newton wrote, “The laws of God & the laws of man are to be kept distinct.” These new, “nonoverlapping spheres of obligation,” Strevens argues, were what made it possible to imagine the iron rule. The rule simply proposed the creation of a third sphere: in addition to God and state, there would now be science.
  • Strevens imagines how, to someone in Descartes’s time, the iron rule would have seemed “unreasonably closed-minded.” Since ancient Greece, it had been obvious that the best thinking was cross-disciplinary, capable of knitting together “poetry, music, drama, philosophy, democracy, mathematics,” and other elevating human disciplines.
  • We’re still accustomed to the idea that a truly flourishing intellect is a well-rounded one. And, by this standard, Strevens says, the iron rule looks like “an irrational way to inquire into the underlying structure of things”; it seems to demand the upsetting “suppression of human nature.”
  • Descartes, in short, would have had good reasons for resisting a law that narrowed the grounds of disputation, or that encouraged what Strevens describes as “doing rather than thinking.”
  • In fact, the iron rule offered scientists a more supple vision of progress. Before its arrival, intellectual life was conducted in grand gestures.
  • Descartes’s book was meant to be a complete overhaul of what had preceded it; its fate, had science not arisen, would have been replacement by some equally expansive system. The iron rule broke that pattern.
  • by authorizing what Strevens calls “shallow explanation,” the iron rule offered an empirical bridge across a conceptual chasm. Work could continue, and understanding could be acquired on the other side. In this way, shallowness was actually more powerful than depth.
  • it also changed what counted as progress. In the past, a theory about the world was deemed valid when it was complete—when God, light, muscles, plants, and the planets cohered. The iron rule allowed scientists to step away from the quest for completeness.
  • The consequences of this shift would become apparent only with time
  • In 1713, Isaac Newton appended a postscript to the second edition of his “Principia,” the treatise in which he first laid out the three laws of motion and the theory of universal gravitation. “I have not as yet been able to deduce from phenomena the reason for these properties of gravity, and I do not feign hypotheses,” he wrote. “It is enough that gravity really exists and acts according to the laws that we have set forth.”
  • What mattered, to Newton and his contemporaries, was his theory’s empirical, predictive power—that it was “sufficient to explain all the motions of the heavenly bodies and of our sea.”
  • Descartes would have found this attitude ridiculous. He had been playing a deep game—trying to explain, at a fundamental level, how the universe fit together. Newton, by those lights, had failed to explain anything: he himself admitted that he had no sense of how gravity did its work
  • Strevens sees its earliest expression in Francis Bacon’s “The New Organon,” a foundational text of the Scientific Revolution, published in 1620. Bacon argued that thinkers must set aside their “idols,” relying, instead, only on evidence they could verify. This dictum gave scientists a new way of responding to one another’s work: gathering data.
  • Quantum theory—which tells us that subatomic particles can be “entangled” across vast distances, and in multiple places at the same time—makes intuitive sense to pretty much nobody.
  • Without the iron rule, Strevens writes, physicists confronted with such a theory would have found themselves at an impasse. They would have argued endlessly about quantum metaphysics.
  • ollowing the iron rule, they can make progress empirically even though they are uncertain conceptually. Individual researchers still passionately disagree about what quantum theory means. But that hasn’t stopped them from using it for practical purposes—computer chips, MRI machines, G.P.S. networks, and other technologies rely on quantum physics.
  • One group of theorists, the rationalists, has argued that science is a new way of thinking, and that the scientist is a new kind of thinker—dispassionate to an uncommon degree.
  • As evidence against this view, another group, the subjectivists, points out that scientists are as hopelessly biased as the rest of us. To this group, the aloofness of science is a smoke screen behind which the inevitable emotions and ideologies hide.
  • At least in science, Strevens tells us, “the appearance of objectivity” has turned out to be “as important as the real thing.”
  • The subjectivists are right, he admits, inasmuch as scientists are regular people with a “need to win” and a “determination to come out on top.”
  • But they are wrong to think that subjectivity compromises the scientific enterprise. On the contrary, once subjectivity is channelled by the iron rule, it becomes a vital component of the knowledge machine. It’s this redirected subjectivity—to come out on top, you must follow the iron rule!—that solves science’s “problem of motivation,” giving scientists no choice but “to pursue a single experiment relentlessly, to the last measurable digit, when that digit might be quite meaningless.”
  • If it really was a speech code that instigated “the extraordinary attention to process and detail that makes science the supreme discriminator and destroyer of false ideas,” then the peculiar rigidity of scientific writing—Strevens describes it as “sterilized”—isn’t a symptom of the scientific mind-set but its cause.
  • The iron rule—“a kind of speech code”—simply created a new way of communicating, and it’s this new way of communicating that created science.
  • Other theorists have explained science by charting a sweeping revolution in the human mind; inevitably, they’ve become mired in a long-running debate about how objective scientists really are
  • In “The Knowledge Machine: How Irrationality Created Modern Science” (Liveright), Michael Strevens, a philosopher at New York University, aims to identify that special something. Strevens is a philosopher of science
  • Compared with the theories proposed by Popper and Kuhn, Strevens’s rule can feel obvious and underpowered. That’s because it isn’t intellectual but procedural. “The iron rule is focused not on what scientists think,” he writes, “but on what arguments they can make in their official communications.”
  • Like everybody else, scientists view questions through the lenses of taste, personality, affiliation, and experience
  • geologists had a professional obligation to take sides. Europeans, Strevens reports, tended to back Wegener, who was German, while scholars in the United States often preferred Simpson, who was American. Outsiders to the field were often more receptive to the concept of continental drift than established scientists, who considered its incompleteness a fatal flaw.
  • Strevens’s point isn’t that these scientists were doing anything wrong. If they had biases and perspectives, he writes, “that’s how human thinking works.”
  • Eddington’s observations were expected to either confirm or falsify Einstein’s theory of general relativity, which predicted that the sun’s gravity would bend the path of light, subtly shifting the stellar pattern. For reasons having to do with weather and equipment, the evidence collected by Eddington—and by his colleague Frank Dyson, who had taken similar photographs in Sobral, Brazil—was inconclusive; some of their images were blurry, and so failed to resolve the matter definitively.
  • it was only natural for intelligent people who were free of the rule’s strictures to attempt a kind of holistic, systematic inquiry that was, in many ways, more demanding. It never occurred to them to ask if they might illuminate more collectively by thinking about less individually.
  • In the single-sphered, pre-scientific world, thinkers tended to inquire into everything at once. Often, they arrived at conclusions about nature that were fascinating, visionary, and wrong.

String Theory: The Best Explanation for Everything in the Universe - The Atlantic - 0 views

  • Somehow, space-time curvature emerges as the collective effect of quantized units of gravitational energy—particles known as gravitons. But naïve attempts to calculate how gravitons interact result in nonsensical infinities, indicating the need for a deeper understanding of gravity.
  • String theory (or, more technically, M-theory) is often described as the leading candidate for the theory of everything in our universe. But there’s no empirical evidence for it, or for any alternative ideas about how gravity might unify with the rest of the fundamental forces. Why, then, is string/M-theory given the edge over the others?
  • For such imaginary worlds, physicists can describe processes at all energies, including, in principle, black-hole formation and evaporation.

A New Alternative to Dark Matter - The Atlantic - 0 views

  • The challenges for alternative gravity theories—collectively known as modified Newtonian dynamics, or MOND—were spelled out in a separate preprint coincidentally published the day after the new model appeared. Chief among them is recasting the leading role dark matter plays in drawing the universe together, as described by a well-established cosmological model known as LCDM, or Lambda cold dark matter.
  • Simply put, LCDM says that we wouldn’t be here without dark matter. The infant universe was so smooth that the gravitational attraction of ordinary matter alone wouldn’t have been enough to gather particles into galaxies, stars, and planets. Enter dark-matter particles. Under the LCDM model, their collective bulk sculpts normal matter into the modern cosmic structures studied by astronomers.
  • LCDM became the standard model of cosmology in part because it so precisely agrees with the CMB. This map of the early universe shows almost imperceptibly thick and thin spots rippling through the cosmos. More recently, researchers have been able to measure the orientation or polarization of the CMB’s light more precisely. Any successful cosmology will need to establish a comprehensive history of the cosmos by reproducing these three observations: the CMB’s temperature, the CMB’s polarization, and the current distribution of galaxies and galaxy clusters.
  • ...7 more annotations...
  • Recreating these and other features without LCDM’s titular ingredient, Spergel showed, requires the finest of theoretical needle threading. “We haven’t disproven the existence of all these [modified-gravity theories],” he says. “But any alternative theory has to jump through these hoops.”
  • Złosnik and Skordis believe they’ve done just that—although in a way that might surprise MOND skeptics and fans alike. They managed to construct a theory of gravity that contains an ingredient that acts exactly like an invisible form of matter on cosmic scales, blurring the line between the dark matter and MOND paradigms.
  • Their theory, dubbed RelMOND, adds to the equations of general relativity an omnipresent field that behaves differently in different arenas. On the grandest scales, where the universe noticeably stretches as it expands, the field acts like invisible matter. In this mode, which Złosnik calls “dark dust,” the field could have shaped the visible universe just as dark matter would
  • RelMOND “cannot do worse than LCDM,” says Złosnik, who notes that it very closely mimics that theory for the universe as a whole.
  • But if we zoom in on a galaxy, where the fabric of space holds rather still, the field acts in a way that’s true to its MOND roots: It entwines itself with the standard gravitational field, beefing it up just enough to hold a galaxy together without extra matter
  • (The researchers aren’t yet sure how the field acts for larger clusters of galaxies, a perennial MOND sore spot. They suggest that this intermediate scale might be a good place to look for observational clues that could set the theory apart.)
  • Despite this mathematical achievement by Złosnik and Skordis, dark matter remains the simpler theory. Constructing the new field takes four new moving mathematical parts, while LCDM handles dark matter with just one. Hooper likens the situation to a detective debating whether a person at a murder scene is the murderer or has been framed by the CIA. Even if the available evidence matches both theories, one requires less of a leap.

An Existential Problem in the Search for Alien Life - The Atlantic - 0 views

  • The fact is, we still don’t know what life is.
  • since the days of Aristotle, scientists and philosophers have struggled to draw a precise line between what is living and what is not, often returning to criteria such as self-organization, metabolism, and reproduction but never finding a definition that includes, and excludes, all the right things.

  • ...20 more annotations...
  • it lacks practical application. If humans found something on another planet that seemed to be alive, how much time would we have to sit around and wait for it to evolve?
  • The only life we know is life on Earth. Some scientists call this the n=1 problem, where n is the number of examples from which we can generalize.
  • Cronin studies the origin of life, also a major interest of Walker’s, and it turned out that, when expressed in math, their ideas were essentially the same. They had both zeroed in on complexity as a hallmark of life. Cronin is devising a way to systematize and measure complexity, which he calls Assembly Theory.
  • What we really want is more than a definition of life. We want to know what life, fundamentally, is. For that kind of understanding, scientists turn to theories. A theory is a scientific fundamental. It not only answers questions, but frames them, opening new lines of inquiry. It explains our observations and yields predictions for future experiments to test.
  • Consider the difference between defining gravity as “the force that makes an apple fall to the ground” and explaining it, as Newton did, as the universal attraction between all particles in the universe, proportional to the product of their masses and so on. A definition tells us what we already know; a theory changes how we understand things.
  • the potential rewards of unlocking a theory of life have captivated a clutch of researchers from a diverse set of disciplines. “There are certain things in life that seem very hard to explain,” Sara Imari Walker, a physicist at Arizona State University who has been at the vanguard of this work, told me. “If you scratch under the surface, I think there is some structure that suggests formalization and mathematical laws.”
  • Walker doesn’t think about life as a biologist—or an astrobiologist—does. When she talks about signs of life, she doesn’t talk about carbon, or water, or RNA, or phosphine. She reaches for different examples: a cup, a cellphone, a chair. These objects are not alive, of course, but they’re clearly products of life. In Walker’s view, this is because of their complexity. Life brings complexity into the universe, she says, in its own being and in its products, because it has memory: in DNA, in repeating molecular reactions, in the instructions for making a chair.
  • He measures the complexity of an object—say, a molecule—by calculating the number of steps necessary to put the object’s smallest building blocks together in that certain way. His lab has found, for example, when testing a wide range of molecules, that those with an “assembly number” above 15 were exclusively the products of life. Life makes some simpler molecules, too, but only life seems to make molecules that are so complex.
  • I reach for the theory of gravity as a familiar parallel. Someone might ask, “Okay, so in terms of gravity, where are we in terms of our understanding of life? Like, Newton?” Further back, further back, I say. Walker compares us to pre-Copernican astronomers, reliant on epicycles, little orbits within orbits, to make sense of the motion we observe in the sky. Cleland has put it in terms of chemistry, in which case we’re alchemists, not even true chemists yet
  • Walker’s whole notion is that it’s not only theoretically possible but genuinely achievable to identify something smaller—much smaller—that still nonetheless simply must be the result of life. The model would, in a sense, function like biosignatures as an indication of life that could be searched for. But it would drastically improve and expand the targets.
  • Walker would use the theory to predict what life on a given planet might look like. It would require knowing a lot about the planet—information we might have about Venus, but not yet about a distant exoplanet—but, crucially, would not depend at all on how life on Earth works, what life on Earth might do with those materials.
  • Without the ability to divorce the search for alien life from the example of life we know, Walker thinks, a search is almost pointless. “Any small fluctuations in simple chemistry can actually drive you down really radically different evolutionary pathways,” she told me. “I can’t imagine [life] inventing the same biochemistry on two worlds.”
  • Walker’s approach is grounded in the work of, among others, the philosopher of science Carol Cleland, who wrote The Quest for a Universal Theory of Life.
  • she warns that any theory of life, just like a definition, cannot be constrained by the one example of life we currently know. “It’s a mistake to start theorizing on the basis of a single example, even if you’re trying hard not to be Earth-centric. Because you’re going to be Earth-centric,” Cleland told me. In other words, until we find other examples of life, we won’t have enough data from which to devise a theory. Abstracting away from Earthliness isn’t a way to be agnostic, Cleland argues. It’s a way to be too abstract.
  • Cleland calls for a more flexible search guided by what she calls “tentative criteria.” Such a search would have a sense of what we’re looking for, but also be open to anomalies that challenge our preconceptions, detections that aren’t life as we expected but aren’t familiar not-life either—neither a flower nor a rock
  • it speaks to the hope that exploration and discovery might truly expand our understanding of the cosmos and our own world.
  • The astrobiologist Kimberley Warren-Rhodes studies life on Earth that lives at the borders of known habitability, such as in Chile’s Atacama Desert. The point of her experiments is to better understand how life might persist—and how it might be found—on Mars. “Biology follows some rules,” she told me. The more of those rules you observe, the better sense you have of where to look on other worlds.
  • In this light, the most immediate concern in our search for extraterrestrial life might be less that we only know about life on Earth, and more that we don’t even know that much about life on Earth in the first place. “I would say we understand about 5 percent,” Warren-Rhodes estimates of our cumulative knowledge. N=1 is a problem, and we might be at more like n=.05.
  • who knows how strange life on another world might be? What if life as we know it is the wrong life to be looking for?
  • We understand so little, and we think we’re ready to find other life?

The decline effect and the scientific method : The New Yorker - 3 views

  • The test of replicability, as it’s known, is the foundation of modern research. Replicability is how the community enforces itself. It’s a safeguard for the creep of subjectivity. Most of the time, scientists know what results they want, and that can influence the results they get. The premise of replicability is that the scientific community can correct for these flaws.
  • But now all sorts of well-established, multiply confirmed findings have started to look increasingly uncertain. It’s as if our facts were losing their truth: claims that have been enshrined in textbooks are suddenly unprovable.

  • The most likely explanation for the decline is an obvious one: regression to the mean. As the experiment is repeated, that is, an early statistical fluke gets cancelled out. The extrasensory powers of Schooler’s subjects didn’t decline—they were simply an illusion that vanished over time.
  • yet Schooler has noticed that many of the data sets that end up declining seem statistically solid—that is, they contain enough data that any regression to the mean shouldn’t be dramatic. “These are the results that pass all the tests,” he says. “The odds of them being random are typically quite remote, like one in a million. This means that the decline effect should almost never happen. But it happens all the time!
  • this is why Schooler believes that the decline effect deserves more attention: its ubiquity seems to violate the laws of statistics

He looked at hundreds of papers and forty-four meta-analyses (that is, statistical syntheses of related studies), and discovered a consistent decline effect over time, as many of the theories seemed to fade into irrelevance.
  • Jennions admits that his findings are troubling, but expresses a reluctance to talk about them
  • publicly. “This is a very sensitive issue for scientists,” he says. “You know, we’re supposed to be dealing with hard facts, the stuff that’s supposed to stand the test of time. But when you see these trends you become a little more skeptical of things.”
  • While publication bias almost certainly plays a role in the decline effect, it remains an incomplete explanation. For one thing, it fails to account for the initial prevalence of positive results among studies that never even get submitted to journals. It also fails to explain the experience of people like Schooler, who have been unable to replicate their initial data despite their best efforts.
  • Jennions, similarly, argues that the decline effect is largely a product of publication bias, or the tendency of scientists and scientific journals to prefer positive data over null results, which is what happens when no effect is found. The bias was first identified by the statistician Theodore Sterling, in 1959, after he noticed that ninety-seven per cent of all published psychological studies with statistically significant data found the effect they were looking for
  • Sterling saw that if ninety-seven per cent of psychology studies were proving their hypotheses, either psychologists were extraordinarily lucky or they published only the outcomes of successful experiments.
  • One of his most cited papers has a deliberately provocative title: “Why Most Published Research Findings Are False.”
  • suspects that an equally significant issue is the selective reporting of results—the data that scientists choose to document in the first place. Palmer’s most convincing evidence relies on a statistical tool known as a funnel graph. When a large number of studies have been done on a single subject, the data should follow a pattern: studies with a large sample size should all cluster around a common value—the true result—whereas those with a smaller sample size should exhibit a random scattering, since they’re subject to greater sampling error. This pattern gives the graph its name, since the distribution resembles a funnel.
  • after Palmer plotted every study of fluctuating asymmetry, he noticed that the distribution of results with smaller sample sizes wasn’t random at all but instead skewed heavily toward positive results. Palmer has since documented a similar problem in several other contested subject areas. “Once I realized that selective reporting is everywhere in science, I got quite depressed,” Palmer told me. “As a researcher, you’re always aware that there might be some nonrandom patterns, but I had no idea how widespread it is.”
  • Palmer summarized the impact of selective reporting on his field: “We cannot escape the troubling conclusion that some—perhaps many—cherished generalities are at best exaggerated in their biological significance and at worst a collective illusion nurtured by strong a-priori beliefs often repeated.”
  • Palmer emphasizes that selective reporting is not the same as scientific fraud. Rather, the problem seems to be one of subtle omissions and unconscious misperceptions, as researchers struggle to make sense of their results. Stephen Jay Gould referred to this as the “sho
  • horning” process.
  • “A lot of scientific measurement is really hard,” Simmons told me. “If you’re talking about fluctuating asymmetry, then it’s a matter of minuscule differences between the right and left sides of an animal. It’s millimetres of a tail feather. And so maybe a researcher knows that he’s measuring a good male”—an animal that has successfully mated—“and he knows that it’s supposed to be symmetrical. Well, that act of measurement is going to be vulnerable to all sorts of perception biases. That’s not a cynical statement. That’s just the way human beings work.”
  • For Simmons, the steep rise and slow fall of fluctuating asymmetry is a clear example of a scientific paradigm, one of those intellectual fads that both guide and constrain research: after a new paradigm is proposed, the peer-review process is tilted toward positive results. But then, after a few years, the academic incentives shift—the paradigm has become entrenched—so that the most notable results are now those that disprove the theory.
  • John Ioannidis, an epidemiologist at Stanford University, argues that such distortions are a serious issue in biomedical research. “These exaggerations are why the decline has become so common,” he says. “It’d be really great if the initial studies gave us an accurate summary of things. But they don’t. And so what happens is we waste a lot of money treating millions of patients and doing lots of follow-up studies on other themes based on results that are misleading.”
  • In 2005, Ioannidis published an article in the Journal of the American Medical Association that looked at the forty-nine most cited clinical-research studies in three major medical journals.
  • the data Ioannidis found were disturbing: of the thirty-four claims that had been subject to replication, forty-one per cent had either been directly contradicted or had their effect sizes significantly downgraded.
  • the most troubling fact emerged when he looked at the test of replication: out of four hundred and thirty-two claims, only a single one was consistently replicable. “This doesn’t mean that none of these claims will turn out to be true,” he says. “But, given that most of them were done badly, I wouldn’t hold my breath.”
  • According to Ioannidis, the main problem is that too many researchers engage in what he calls “significance chasing,” or finding ways to interpret the data so that it passes the statistical test of significance—the ninety-five-per-cent boundary invented by Ronald Fisher.
  • One of the classic examples of selective reporting concerns the testing of acupuncture in different countries. While acupuncture is widely accepted as a medical treatment in various Asian countries, its use is much more contested in the West. These cultural differences have profoundly influenced the results of clinical trials.
  • The problem of selective reporting is rooted in a fundamental cognitive flaw, which is that we like proving ourselves right and hate being wrong.
  • “It feels good to validate a hypothesis,” Ioannidis said. “It feels even better when you’ve got a financial interest in the idea or your career depends upon it. And that’s why, even after a claim has been systematically disproven”—he cites, for instance, the early work on hormone replacement therapy, or claims involving various vitamins—“you still see some stubborn researchers citing the first few studies
  • That’s why Schooler argues that scientists need to become more rigorous about data collection before they publish. “We’re wasting too much time chasing after bad studies and underpowered experiments,”
  • The current “obsession” with replicability distracts from the real problem, which is faulty design.
  • “Every researcher should have to spell out, in advance, how many subjects they’re going to use, and what exactly they’re testing, and what constitutes a sufficient level of proof. We have the tools to be much more transparent about our experiments.”
  • Schooler recommends the establishment of an open-source database, in which researchers are required to outline their planned investigations and document all their results. “I think this would provide a huge increase in access to scientific work and give us a much better way to judge the quality of an experiment,”
  • scientific research will always be shadowed by a force that can’t be curbed, only contained: sheer randomness. Although little research has been done on the experimental dangers of chance and happenstance, the research that exists isn’t encouraging.
  • The disturbing implication of the Crabbe study is that a lot of extraordinary scientific data are nothing but noise. The hyperactivity of those coked-up Edmonton mice wasn’t an interesting new fact—it was a meaningless outlier, a by-product of invisible variables we don’t understand.
  • The problem, of course, is that such dramatic findings are also the most likely to get published in prestigious journals, since the data are both statistically significant and entirely unexpected
  • This suggests that the decline effect is actually a decline of illusion. While Karl Popper imagined falsification occurring with a single, definitive experiment—Galileo refuted Aristotelian mechanics in an afternoon—the process turns out to be much messier than that.
  • Many scientific theories continue to be considered true even after failing numerous experimental tests.
  • Even the law of gravity hasn’t always been perfect at predicting real-world phenomena. (In one test, physicists measuring gravity by means of deep boreholes in the Nevada desert found a two-and-a-half-per-cent discrepancy between the theoretical predictions and the actual data.)
  • Such anomalies demonstrate the slipperiness of empiricism. Although many scientific ideas generate conflicting results and suffer from falling effect sizes, they continue to get cited in the textbooks and drive standard medical practice. Why? Because these ideas seem true. Because they make sense. Because we can’t bear to let them go. And this is why the decline effect is so troubling. Not because it reveals the human fallibility of science, in which data are tweaked and beliefs shape perceptions. (Such shortcomings aren’t surprising, at least for scientists.) And not because it reveals that many of our most exciting theories are fleeting fads and will soon be rejected. (That idea has been around since Thomas Kuhn.)
  • The decline effect is troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that’s often not the case. Just because an idea is true doesn’t mean it can be proved. And just because an idea can be proved doesn’t mean it’s true. When the experiments are done, we still have to choose what to believe. ♦

Sullivan: Is Political Gravity Finally Sinking Donald Trump? - 0 views

  • “We are not afraid,” declared Prime Minister Theresa May after the latest Islamist horror on Westminster Bridge. She went on about the importance of being “normal.” It’s a very British response to terrorism. It’s called stoicism — a quality unknown, it appears, in the home of the “brave.”
  • Compare this with, say, the reaction to the Boston marathon bombing. An entire city was brought to a standstill and locked down, while the pursuit of a deranged, unarmed teenager continued. You can understand that, I suppose, given that the suspect was still at large. But to subsequently celebrate the event with the slogan “Boston Strong” was perverse. The truth was: “Boston Shit-Scared.”

Until we get over that, until we manage to stiffen our upper lips like the Brits, jihadist terrorists will exercise control over the American psyche like no one else. We can do better, can’t we? If we want the Constitution to survive both Islamism’s threat and the potential response of a beleaguered Trump, we’ll have to.

'Trespassing on Einstein's Lawn,' by Amanda Gefter - NYTimes.com - 0 views

  • It all began when Warren Gefter, a radiologist “prone to posing Zen-koan-like questions,” asked his 15-year-old daughter, Amanda, over dinner at a Chinese restaurant near their home just outside Philadelphia: “How would you define nothing?”
  • “I think we should figure it out,” he said. And his teenage daughter — sullen, rebellious, wallowing in existential dread — smiled for the first time “in what felt like years.” The project proved to be a gift from a wise, insightful father. It was Warren Gefter’s way of rescuing his child.
  • Tracking down the meaning of nothing — and, by extension, secrets about the origin of the universe and whether observer-independent reality exists — became the defining project of their lives. They spent hours together working on the puzzle, two dark heads bent over their physics books far into the night.

  • “If observers create reality, where do the observers come from?” But the great man responded in riddles. “The universe is a self-­excited circuit,” Wheeler said. “The boundary of a boundary is zero.” The unraveling of these mysteries propels the next 400 or so pages.

They discuss her insight over breakfast at a neighborhood haunt, where they make a list on what they will affectionately call “the IHOP napkin.” They list all the possible “ingredients of ultimate reality,” planning to test each item for whether it is “real,” that is whether it is invariant and can exist in the absence of an observer.
  • their readings and interviews reveal that each item in turn is observer-dependent. Space? Observer-dependent, and therefore not real. Gravity, electromagnetism, angular momentum? No, no, and no. In the end, every putative “ingredient of ultimate reality” is eliminated, including one they hadn’t even bothered to put on the list because it seemed weird to: reality itself
  • What remained was an unsettling and essential insight: that “physics isn’t the machinery behind the workings of the world; physics is the machinery behind the illusion that there is a world.”

Owner of a Credit Card Processor Is Setting a New Minimum Wage: $70,000 a Year - NYTime... - 1 views

  • Mr. Price surprised his 120-person staff by announcing that he planned over the next three years to raise the salary of even the lowest-paid clerk, customer service representative and salesman to a minimum of $70,000.
  • Mr. Price, who started the Seattle-based credit-card payment processing firm in 2004 at the age of 19, said he would pay for the wage increases by cutting his own salary from nearly $1 million to $70,000 and using 75 to 80 percent of the company’s anticipated $2.2 million in profit this year.

  • The United States has one of the world’s largest pay gaps, with chief executives earning nearly 300 times what the average worker makes, according to some economists’ estimates. That is much higher than the 20-to-1 ratio recommended by Gilded Age magnates like J. Pierpont Morgan and the 20th century management visionary Peter Drucker.
  • “The market rate for me as a C.E.O. compared to a regular person is ridiculous, it’s absurd,” said Mr. Price, who said his main extravagances were snowboarding and picking up the bar bill. He drives a 12-year-old Audi
  • Under a financial overhaul passed by Congress in 2010, the Securities and Exchange Commission was supposed to require all publicly held companies to disclose the ratio of C.E.O. pay to the median pay of all other employees, but it has so far failed to put it in effect. Corporate executives have vigorously opposed the idea, complaining it would be cumbersome and costly to implement.
  • Of all the social issues that he felt he was in a position to do something about as a business leader, “that one seemed like a more worthy issue to go after.”
  • The happiness research behind Mr. Price’s announcement on Monday came from Angus Deaton and Daniel Kahneman, a Nobel Prize-winning psychologist. They found that what they called emotional well-being — defined as “the emotional quality of an individual’s everyday experience, the frequency and intensity of experiences of joy, stress, sadness, anger, and affection that make one’s life pleasant or unpleasant” — rises with income, but only to a point. And that point turns out to be about $75,000 a year.
  • Of course, money above that level brings pleasures — there’s no denying the delights of a Caribbean cruise or a pair of diamond earrings — but no further gains on the emotional well-being scale.
  • As Mr. Kahneman has explained it, income above the threshold doesn’t buy happiness, but a lack of money can deprive you of it.

Gravity Probe B Project Confirms Einstein Space-Time Ideas - NYTimes.com - 0 views

  • Observations of planets, the Moon and particularly the shifting orbits of the Lageos research satellites had convinced astronomers and physicists that Einstein’s predictions were on the mark. Nevertheless, scientists said that the Gravity Probe results would live forever in textbooks as the most direct measurements, and that it was important to keep testing theories that were thought to be correct.
  • Empty space in the vicinity of Earth is indeed turning, Dr. Everitt reported at the news conference and in a paper prepared for the journal Physical Review Letters, at the leisurely rate of 37 one-thousandths of a second of arc — the equivalent of a human hair seen from 10 miles away — every year. With an uncertainty of 19 percent, that measurement was in agreement with Einstein’s predictions of 39 milliarcseconds.

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?

  • 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.

Great leaders are foremost creators of stories.”

To this end, we create models, modern parables,

  • The History of Animal Spirits: Dreams Never Sleep
  • In this sense, “the study of economics is too narrow and too fragmentary to lead to valid insight, unless complemented and completed by a study of metaeconomics.”17
  • The more important elements of a culture or field of inquiry such as economics are found in fundamental assumptions that adherents of all the various systems within the epoch unconsciously presuppose. Such assumptions appear so obvious that people do not know what they are assuming, because no other way of putting things has ever occurred to them, as the philosopher Alfred Whitehead notes in Adventures of Ideas.
  • I argue that economic questions were with mankind long before Adam Smith. I argue that the search for values in economics did not start with Adam Smith but culminated with him.
  • We should go beyond economics and study what beliefs are “behind the scenes,” ideas that have often become the dominant yet unspoken assumptions in our theories. Economics is surprisingly full of tautologies that economists are predominantly unaware of. I
  • argue that economics should seek, discover, and talk about its own values, although we have been taught that economics is a value-free science. I argue that none of this is true and that there is more religion, myth, and archetype in economics than there is mathematics.
  • In a way, this is a study of the evolution of both homo economicus and, more importantly, the history of the animal spirits within him. This book tries to study the evolution of the rational as well as the emotional and irrational side of human beings.
  • I argue that his most influential contribution to economics was ethical. His other thoughts had been clearly expressed long before him, whether on specialization, or on the principle of the invisible hand of the market. I try to show that the principle of the invisible hand of the market is much more ancient and developed long before Adam Smith. Traces of it appear even in the Epic of Gilgamesh, Hebrew thought, and in Christianity, and it is expressly stated by Aristophanes and Thomas Aquinas.

  • The History of the Invisible Hand of the Market and Homo Economicus
  • We understand “economics” to mean a broader field than just the production, distribution, and consumption of goods and services. We consider economics to be the study of human relations that are sometimes expressible in numbers, a study that deals with tradables, but one that also deals with nontradables (friendship, freedom, efficiency, growth).
  • When we mention economics in this book, we mean the mainstream perception of it, perhaps as best represented by Paul Samuelson.
  • By the term homo economicus, we mean the primary concept of economic anthropology. It comes from the concept of a rational individual, who, led by narrowly egotistical motives, sets out to maximize his benefit.

  • Gilgamesh becomes a hero not only due to his strength, but also due to discoveries and deeds whose importance were in large part economic—direct gaining of construction materials in the case of felling the cedar forest, stopping Enkidu from devastating Uruk’s economy, and discovering new desert routes during his expeditions.
  • Even today, we often consider the domain of humanity (human relations, love, friendship, beauty, art, etc.) to be unproductive;
  • Even today we live in Gilgamesh’s vision that human relations—and therefore humanity itself—are a disturbance to work and efficiency; that people would perform better if they did not “waste” their time and energy on nonproductive things.
  • But it is in friendship where—often by-the-way, as a side product, an externality—ideas and deeds are frequently performed or created that together can altogether change the face of society.19 Friendship can go against an ingrained system in places where an individual does not have the courage to do so himself or herself.
  • As Joseph Stiglitz says, One of the great “tricks” (some say “insights”) of neoclassical economics is to treat labour like any other factor of production. Output is written as a function of inputs—steel, machines, and labour. The mathematics treats labour like any other commodity, lulling one into thinking of labour like an ordinary commodity, such as steel or plastic.
  • Even the earliest cultures were aware of the value of cooperation on the working level—today we call this collegiality, fellowship, or, if you want to use a desecrated term, comradeship. These “lesser relationships” are useful and necessary for society and for companies because work can be done much faster and more effectively if people get along with each other on a human level
  • But true friendship, which becomes one of the central themes of the Epic of Gilgamesh, comes from completely different material than teamwork. Friendship, as C. S. Lewis accurately describes it, is completely uneconomical, unbiological, unnecessary for civilization, and an unneeded relationship
  • Here we have a beautiful example of the power of friendship, one that knows how to transform (or break down) a system and change a person. Enkidu, sent to Gilgamesh as a punishment from the gods, in the end becomes his faithful friend, and together they set out against the gods. Gilgamesh would never have gathered the courage to do something like that on his own—nor would Enkidu.
  • Due to their friendship, Gilgamesh and Enkidu then intend to stand up to the gods themselves and turn a holy tree into mere (construction) material they can handle almost freely, thereby making it a part of the city-construct, part of the building material of civilization, thus “enslaving” that which originally was part of wild nature. This is a beautiful proto-example of the shifting of the borders between the sacred and profane (secular)—and to a certain extent also an early illustration of the idea that nature is there to provide cities and people with raw material and production resources.
  • started with Babylonians—rural nature becomes just a supplier of raw materials, resources (and humans the source of human resources). Nature is not the garden in which humans were created and placed, which they should care for and which they should reside in, but becomes a mere reservoir for natural (re)sources.
  • But labour is unlike any other commodity. The work environment is of no concern for steel; we do not care about steel’s well-being.16
  • Both heroes change—each from opposite poles—into humans. In this context, a psychological dimension to the story may be useful: “Enkidu (…) is Gilgamesh’s alter ego, the dark, animal side of his soul, the complement to his restless heart. When Gilgamesh found Enkidu, he changed from a hated tyrant into the protector of his city. (…)

Here we see what early cultures considered the beginning of civilization. Here is depicted the difference between people and animals or, better, savages. Here the epic quietly describes birth, the awakening of a conscious, civilized human. We are witnesses to the emancipation of humanity from animals,
  • The entire history of culture is dominated by an effort to become as independent as possible from the whims of nature.39 The more developed a civilization is, the more an individual is protected from nature and natural influences and knows how to create around him a constant or controllable environment to his liking.
  • The price we pay for independence from the whims of nature is dependence on our societies and civilizations. The more sophisticated a given society is as a whole, the less its members are able to survive on their own as individuals, without society.
  • The epic captures one of the greatest leaps in the development of the division of labor. Uruk itself is one of the oldest cities of all, and in the epic it reflects a historic step forward in specialization—in the direction of a new social city arrangement. Because of the city wall, people in the city can devote themselves to things other than worrying about their own safety, and they can continue to specialize more deeply.
  • Human life in the city gains a new dimension and suddenly it seems more natural to take up issues going beyond the life span of an individual. “The city wall symbolizes as well as founds the permanence of the city as an institution which will remain forever and give its inhabitants the certainty of unlimited safety, allowing them to start investing with an outlook reaching far beyond the borders of individual life.
  • The wall around the city of Uruk is, among other things, a symbol of an internal distancing from nature, a symbol of revolts against submission to laws that do not come under the control of man and that man can at most discover and use to his benefit.
  • “The chief thing which the common-sense individual wants is not satisfactions for the wants he had, but more, and better wants.”47
  • If a consumer buys something, theoretically it should rid him of one of his needs—and the aggregate of things they need should be decreased by one item. In reality, though, the aggregate of “I want to have” expands together with the growing aggregate of “I have.”
  • can be said that Enkidu was therefore happy in his natural state, because all of his needs were satiated. On the other hand, with people, it appears that the more a person has, the more developed and richer, the greater the number of his needs (including the unsaturated ones).
  • the Old Testament, this relationship is perceived completely differently. Man (humanity) is created in nature, in a garden. Man was supposed to care for the Garden of Eden and live in harmony with nature and the animals. Soon after creation, man walks naked and is not ashamed, de facto the same as the animals. What is characteristic is that man dresses (the natural state of creation itself is not enough for him), and he (literally and figuratively) covers52 himself—in shame after the fall.53
  • Nature is where one goes to hunt, collect crops, or gather the harvest. It is perceived as the saturator of our needs and nothing more. One goes back to the city to sleep and be “human.” On the contrary, evil resides in nature. Humbaba lives in the cedar forest, which also happens to be the reason to completely eradicate it.
  • Symbolically, then, we can view the entire issue from the standpoint of the epic in the following way: Our nature is insufficient, bad, evil, and good (humane) occurs only after emancipation from nature (from naturalness), through culturing and education. Humanity is considered as being in civilization.
  • The city was frequently (at least in older Jewish writings) a symbol of sin, degeneration, and decadence—nonhumanity. The Hebrews were originally a nomadic nation, one that avoided cities. It is no accident that the first important city57 mentioned in the Bible is proud Babylon,58 which God later turns to dust.
  • is enough, for example, to read the Book of Revelation to see how the vision of paradise developed from the deep Old Testament period, when paradise was a garden. John describes his vision of heaven as a city—paradise is in New Jerusalem, a city where the dimensions of the walls(!) are described in detail, as are the golden streets and gates of pearl.
  • Hebrews later also chose a king (despite the unanimous opposition of God’s prophets) and settled in cities, where they eventually founded the Lord’s Tabernacle and built a temple for Him. The city of Jerusalem later gained an illustrious position in all of religion.
  • this time Christianity (as well as the influence of the Greeks) does not consider human naturalness to be an unambiguous good, and it does not have such an idyllic relationship to nature as the Old Testament prophets.
  • If a tendency toward good is not naturally endowed in people, it must be imputed from above through violence or at least the threat of violence.
  • If we were to look at human naturalness as a good, then collective social actions need a much weaker ruling hand. If people themselves have a natural tendency (propensity) toward good, this role does not have to be supplied by the state, ruler, or, if you wish, Leviathan.
  • How does this affect economics?
  • us return for the last time to the humanization of the wild Enkidu, which is a process we can perceive with a bit of imagination as the first seed of the principle of the market’s invisible hand, and therefore the parallels with one of the central schematics of economic thinking.
  • Sometimes it is better to “harness the devil to the plow” than to fight with him. Instead of summoning up enormous energy in the fight against evil, it is better to use its own energy to reach a goal we desire; setting up a mill on the turbulent river instead of futile efforts to remove the current. This is also how Saint Prokop approached it in one of the oldest Czech legends.
  • Enkidu caused damage and it was impossible to fight against him. But with the help of a trap, trick, this evil was transformed into something that greatly benefited civilization.
  • By culturing and “domesticating” Enkidu, humanity tamed the uncontrollable wild and chaotic evil
  • Enkidu devastated the doings (the external, outside-the-walls) of the city. But he was later harnessed and fights at the side of civilization against nature, naturalness, the natural state of things.
  • A similar motif appears a thousand years after the reversal, which is well known even to noneconomists as the central idea of economics: the invisible hand of the market.
  • A similar story (reforming something animally wild and uncultivated in civilizational achievement) is used by Thomas Aquinas in his teachings. Several centuries later, this idea is fully emancipated in the hands of Bernard Mandeville and his Fable of the Bees: or, Private Vices, Publick Benefits. The economic and political aspects of this idea are—often incorrectly—ascribed to Adam Smith.
  • Here the individual does not try anymore to maximize his goods or profits, but what is important is writing his name in human memory in the form of heroic acts or deeds.
  • immortality, one connected with letters and the cult of the word: A name and especially a written name survives the body.”77
  • After this disappointment, he comes to the edge of the sea, where the innkeeper Siduri lives. As tonic for his sorrow, she offers him the garden of bliss, a sort of hedonistic fortress of carpe diem, where a person comes to terms with his mortality and at least in the course of the end of his life maximizes earthly pleasures, or earthly utility.
  • In the second stage, after finding his friend Enkidu, Gilgamesh abandons the wall and sets out beyond the city to maximalize heroism. “In his (…) search of immortal life, Gilgamesh
  • The hero refuses hedonism in the sense of maximizing terrestrial pleasure and throws himself into things that will exceed his life. In the blink of an eye, the epic turns on its head the entire utility maximization role that mainstream economics has tirelessly tried to sew on people as a part of their nature.81
  • It is simpler to observe the main features of our civilization at a time when the picture was more readable—at a time when our civilization was just being born and was still “half-naked.” In other words, we have tried to dig down to the bedrock of our written civilization;
  • today remember Gilgamesh for his story of heroic friendship with Enkidu, not for his wall, which no longer reaches monumental heights.
  • the eleventh and final tablet, Gilgamesh again loses what he sought. Like Sisyphus, he misses his goal just before the climax
  • is there something from it that is valid today? Have we found in Gilgamesh certain archetypes that are in us to this day?
  • The very existence of questions similar to today’s economic ones can be considered as the first observation. The first written considerations of the people of that time were not so different from those today. In other words: The epic is understandable for us, and we can identify with it.
  • We have also been witnesses to the very beginnings of man’s culturing—a great drama based on a liberation and then a distancing from the natural state.
  • Let us take this as a memento in the direction of our restlessness, our inherited dissatisfaction and the volatility connected to it. Considering that they have lasted five thousand years and to this day we find ourselves in harmony with a certain feeling of futility, perhaps these characteristics are inherent in man.
  • Gilgamesh had a wall built that divided the city from wild nature and created a space for the first human culture. Nevertheless, “not even far-reaching works of civilization could satisfy human desire.”
  • Friendship shows us new, unsuspected adventures, gives us the opportunity to leave the wall and to become neither its builder nor its part—to not be another brick in the wall.
  • with the phenomenon of the creation of the city, we have seen how specialization and the accumulation of wealth was born, how holy nature was transformed into a secular supplier of resources, and also how humans’ individualistic ego was emancipated.
  • to change the system, to break down that which is standing and go on an expedition against the gods (to awaken, from naïveté to awakening) requires friendship.
  • For small acts (hunting together, work in a factory), small love is enough: Camaraderie. For great acts, however, great love is necessary, real love: Friendship. Friendship that eludes the economic understanding of quid pro quo. Friendship gives. One friend gives (fully) for the other. That is friendship for life and death,
  • The thought that humanity comes at the expense of efficiency is just as old as humanity itself—as we have shown, subjects without emotion are the ideal of many tyrants.
  • The epic later crashes this idea through the friendship of Gilgamesh and Enkidu. Friendship—the biologically least essential love, which at first sight appears to be unnecessary
  • less a civilized, city person is dependent on nature, the more he or she is dependent on the rest of society. Like Enkidu, we have exchanged nature for society; harmony with (incalculable) nature for harmony with (incalculable) man.
  • human nature good or evil? To this day these questions are key for economic policy: If we believe that man is evil in his nature, therefore that a person himself is dog eat dog (animal), then the hard hand of a ruler is called for. If we believe that people in and of themselves, in their nature, gravitate toward good, then it is possible to loosen up the reins and live in a society that is more laissez-faire.
  • For a concept of historical progress, for the undeification of heroes, rulers, and nature, mankind had to wait for the Hebrews.
  • Because nature is not undeified, it is beyond consideration to explore it, let alone intervene in it (unless a person was a two-thirds god like Gilgamesh). It

  • As regards modern capitalism (as opposed to the ancient and medieval periods) … there are activities in it which are, in certain forms, inherently (and completely necessarily) present—both from an economic and legal standpoint.7
  • As early as the “dark” ages, the Jews commonly used economic tools that were in many ways ahead of their time and that later became key elements of the modern economy:
  • Gilgamesh’s story ends where it began. There is a consistency in this with Greek myths and fables: At the end of the story, no progress occurs, no essential historic change; the story is set in indefinite time, something of a temporal limbo.
  • Jews believe in historical progress, and that progress is in this world.
  • For a nation originally based on nomadism, where did this Jewish business ethos come from? And can the Hebrews truly be considered as the architects of the values that set the direction of our civilization’s economic thought?
  • Hebrew religiosity is therefore strongly connected with this world, not with any abstract world, and those who take pleasure in worldly possessions are not a priori doing anything wrong.
  • PROGRESS: A SECULARIZED RELIGION One of the things the writers of the Old Testament gave to mankind is the idea and notion of progress. The Old Testament stories have their development; they change the history of the Jewish nation and tie in to each other. The Jewish understanding of time is linear—it has a beginning and an end.
  • The observance of God’s Commandments in Judaism leads not to some ethereal other world, but to an abundance of material goods (Genesis 49:25–26, Leviticus 26:3–13, Deuteronomy 28:1–13) (…) There are no accusing fingers pointed at
  • There are no echoes of asceticism nor for the cleansing and spiritual effect of poverty. It is fitting therefore, that the founders of Judaism, the Patriarchs Abraham, Isaac and Jacob, were all wealthy men.12
  • about due to a linear understanding of history. If history has a beginning as well as an end, and they are not the same point, then exploration suddenly makes sense in areas where the fruits are borne only in the next generation.
  • What’s more, economic progress has almost become an assumption of modern functional societies. We expect growth. We take it automatically. Today, if nothing “new” happens, if GDP does not grow (we say it stagnates) for several quarters, we consider it an anomaly.
  • however, the idea of progress itself underwent major changes, and today we perceive it very differently. As opposed to the original spiritual conceptions, today we perceive progress almost exclusively in an economic or scientific-technological sense.
  • Because care for the soul has today been replaced by care for external things,
  • This is why we must constantly grow, because we (deep down and often implicitly) believe that we are headed toward an (economic) paradise on Earth.
  • Only since the period of scientific-technological revolution (and at a time when economics was born as an independent field) is material progress automatically assumed.
  • Jewish thought is the most grounded, most realistic school of thought of all those that have influenced our culture.17 An abstract world of ideas was unknown to the Jews. To this day it is still forbidden to even depict God, people, and animals in symbols, paintings, statues, and drawings.
  • economists have become key figures of great importance in our time (Kacířské eseje o filosofii dějin [Heretical Essays in the Philosophy of History]). They are expected to perform interpretations of reality, give prophetic services (macroeconomic forecasts), reshape reality (mitigate the impacts of the crisis, speed up growth), and, in the long run, provide leadership on the way to the Promised Land—paradise on Earth.
  • REALISM AND ANTIASCETICISM Aside from ideas of progress, the Hebrews brought another very fundamental contribution to our culture: The desacralization of heroes, nature, and rulers.
  • Voltaire writes: “It certain fact is, that in his public laws he [Moses] never so much as once made mention of a life to come, limiting all punishments and all rewards to the present life.”21
  • As opposed to Christianity, the concept of an extraterrestrial paradise or heaven was not developed much in Hebrew thought.19 The paradise of the Israelites—Eden—was originally placed on Earth at a given place in Mesopotamia20 and at a given time,
  • The Hebrews consider the world to be real—not just a shadow reflection of a better world somewhere in the cloud of ideas, something the usual interpretation of history ascribes to Plato. The soul does not struggle against the body and is not its prisoner, as Augustine would write later.
  • The land, the world, the body, and material reality are for Jews the paramount setting for divine history, the pinnacle of creation. This idea is the conditio sine qua non of the development of economics, something of an utterly earthly making,
  • The mythology of the hero-king was strongly developed in that period, which Claire Lalouette summarizes into these basic characteristics: Beauty (a perfect face, on which it is “pleasant to look upon,” but also “beauty,” expressed in the Egyptian word nefer, not only means aesthetics, but contains moral qualities as well),
  • THE HERO AND HIS UNDEIFICATION: THE DREAM NEVER SLEEPS The concept of the hero is more important than it might appear. It may be the remote origin of Keynes’s animal spirits, or the desire to follow a kind of internal archetype that a given individual accepts as his own and that society values.
  • This internal animator of ours, our internal mover, this dream, never sleeps and it influences our behavior—including economic behavior—more than we want to realize.
  • manliness and strength,28 knowledge and intelligence,29 wisdom and understanding, vigilance and performance, fame and renown (fame which overcomes enemies because “a thousand men would not be able to stand firmly in his presence”);30 the hero is a good shepherd (who takes care of his subordinates), is a copper-clad rampart, the shield of the land, and the defender of heroes.
  • Each of us probably has a sort of “hero within”—a kind of internal role-model, template, an example that we (knowingly or not) follow. It is very important what kind of archetype it is, because its role is dominantly irrational and changes depending on time and the given civilization.
  • The oldest was the so-called Trickster—a fraudster; then the culture bearer—Rabbit; the musclebound hero called Redhorn; and finally the most developed form of hero: the Twins.
  • the Egyptian ruler, just as the Sumerian, was partly a god, or the son of a god.31
  • Jacob defrauds his father Isaac and steals his brother Esau’s blessing of the firstborn. Moses murders an Egyptian. King David seduces the wife of his military commander and then has him killed. In his old age, King Solomon turns to pagan idols, and so on.
  • Anthropology knows several archetypes of heroes. The Polish-born American anthropologist Paul Radin examined the myths of North American Indians and, for example, in his most influential book, The Trickster, he describes their four basic archetypes of heroes.
  • The Torah’s heroes (if that term can be used at all) frequently make mistakes and their mistakes are carefully recorded in the Bible—maybe precisely so that none of them could be deified.32
  • We do not have to go far for examples. Noah gets so drunk he becomes a disgrace; Lot lets his own daughters seduce him in a similar state of drunkenness. Abraham lies and (repeatedly) tries to sell his wife as a concubine.
  • the Hebrew heroes correspond most to the Tricksters, the Culture Bearers, and the Twins. The divine muscleman, that dominant symbol we think of when we say hero, is absent here.
  • To a certain extent it can be said that the Hebrews—and later Christianity—added another archetype, the archetype of the heroic Sufferer.35 Job
  • Undeification, however, does not mean a call to pillage or desecration; man was put here to take care of nature (see the story of the Garden of Eden or the symbolism of the naming of the animals). This protection and care of nature is also related to the idea of progress
  • For the heroes who moved our civilization to where it is today, the heroic archetypes of the cunning trickster, culture bearer, and sufferer are rather more appropriate.
  • the Old Testament strongly emphasizes the undeification of nature.37 Nature is God’s creation, which speaks of divinity but is not the domain of moody gods
  • This is very important for democratic capitalism, because the Jewish heroic archetype lays the groundwork much better for the development of the later phenomenon of the hero, which better suits life as we know it today. “The heroes laid down their arms and set about trading to become wealthy.”
  • in an Old Testament context, the pharaoh was a mere man (whom one could disagree with, and who could be resisted!).
  • RULERS ARE MERE MEN In a similar historical context, the Old Testament teachings carried out a similar desacralization of rulers, the so-called bearers of economic policy.
  • Ultimately the entire idea of a political ruler stood against the Lord’s will, which is explicitly presented in the Torah. The Lord unequivocally preferred the judge as the highest form of rule—an

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

  • Saturday was not established to increase efficiency. It was a real ontological break that followed the example of the Lord’s seventh day of creation. Just as the Lord did not rest due to tiredness or to regenerate strength; but because He was done. He was done with His work, so that He could enjoy it, to cherish in His creation.
  • If we believe in rest at all today, it is for different reasons. It is the rest of the exhausted machine, the rest of the weak, and the rest of those who can’t handle the tempo. It’s no wonder that the word “rest…
  • Related to this, we have studied the first mention of a business cycle with the pharaoh’s dream as well as seen a first attempt (that we may call…

  • ancient Greek economic ethos, we will examine two extreme approaches to laws and rules. While the Stoics considered laws to be absolutely valid, and utility had infinitesimal meaning in their philosophy, the Epicureans, at least in the usual historical explanation, placed utility and pleasure in first place—rules were to be made based on the principle of utility.

In the end, poetry could be more sensitive to the truth than the philosophical method or, later, the scientific method. “Tragic poems, in virtue of their subject matter and their social function, are likely to confront and explore problems about human beings and luck that a philosophical text might be able to omit or avoid.”8

Nimuno Loops Invents LEGO Sticky Tape So You Can Build Vertical or Even Defy Gravity | ... - 1 views

  • The creators of the Nimuno Loops tape have done some genius inventing bringing us a product that makes you wonder why no one else has come up with it before.
  • They have created the world's first toy block compatible tape — simple, versatile, cheap, and promising unlimited creative possibilities.
  •  
    LEGO is one of my favorite toy from when I was little. The creativities in those building blocks inspired my mind. Different series have different building blocks but they are all very creative and interesting. And now, they have come up with a new idea of LEGO-compatible tape. I think this is a very genius idea. This invention is a combination of age and LEGO building boards and I am amazed at people's ability of drawing useful connections between totally different object. I think it show how the advantage of making connections in human mind benefit our life and mindset. --Sissi (3/31/2017)

The Way Bosses Conduct And Communicate Layoffs Is Inhumane. There's Another Way. | Huff... - 1 views

  • During my first mass layoff, my manager called it an “impact.” She gathered some of us into a room and informed us that our colleagues who weren’t present had been impacted by our tech company’s latest pivot.
  • Sandra Sucher, a professor of management at Harvard Business School who has researched layoffs, told me the use of these discomforting metaphors has a name. What these bosses are doing is a form of moral disengagement, she said, a phenomenon first identified by Stanford psychologist Albert Bandura.
  • “One of the types of moral disengagement is euphemistic labeling. So instead of saying, ‘I am ending Sandra’s employment where she has worked for 15 years,' 'I am restructuring.'”

  • “‘You will be personally be affected by this, here’s what we’re doing, here’s what we’re doing to help you relocate.’ They’re acknowledging they are doing harm by talking to people in very direct ways,” she said.
  • Beyond making language reflect the gravity of the occasion, employers need to make sure their actions support it, too. Generous severance packages, a meaningful rationale for the downsizing, and treating the victims of a layoff with dignity and respect are all actions employees scrutinize to decide if a layoff was fair.
  • “We have had cases where it just wasn’t taken seriously. Swimming pool, the kids in the background, you’re wearing a Hawaiian shirt, not respecting the gravity of the situation,” he said.
  • Abrupt notification is the norm in many companies, but Sucher said it shouldn’t be. “The best practice in this area would almost never look like today is the first day you heard what’s going to happen to you and it’s also your last day at the company,” she said.

TOK Natural Science as an Area of Knowledge (AOK) - Amor Sciendi - 0 views

  • There are, however, others who declare that these claims are not of the Natural Sciences. A knowledge claim in the natural sciences needs to be falsifiable in order to be tested, and claims regarding a multiverse are not falsifiable. This view of science is most closely associated with the philosopher of science Karl Popper and more recently by Neil Degrasse Tyson. Tyson claims that the multiverse theory, and others like it, do not fall under “science”, but “philosophy”. He claims that in physics, for example, a concept constitutes knowledge if it accurately predicts the future and can be tested empirically. Questions about why certain models work can be discussed and debated over dinner, but those ‘why’ questions are not scientific. We can predict where the moon will be at any given time on the strength of our equations, but questions about why those equations work are for philosophers if they cannot be answered with a falsifiable claim.
  • The natural sciences rely heavily on reason, in particular inductive reasoning. The statement, “all bodies observed so far obey Newton’s law of gravity” has been used to justify a believe in Newton’s law of gravity. Belief structures like this are the backbone of Natural Science, but there are notable philosophers of science who are quick to point out the fallacy of induction. David Hume, for example, questioned the assumption he referred to as the “uniformity of nature”. In short, simply because all observed bodies follow a pattern tell us nothing of unobserved bodies, and the “uniformity of nature” (the belief that nature behaves uniformly) cannot be proven. This brings us to....

4 Everyday Items Einstein Helped Create - 0 views

  • Albert Einstein is justly famous for devising his theory of relativity, which revolutionized our understanding of space, time, gravity, and the universe. Relativity also showed us that matter and energy are just two different forms of the same thing—a fact that Einstein expressed as E=mc2, the most widely recognized equation in history.
  • Credit for inventing paper towels goes to the Scott Paper Company of Pennsylvania, which introduced the disposable product in 1907 as a more hygienic alternative to cloth towels. But in the very first physics article that Einstein ever published, he did analyze wicking: the phenomenon that allows paper towels to soak up liquids even when gravity wants to drag the fluid downward.
  • Again, Einstein didn’t invent solar cells; the first crude versions of them date back to 1839. But he did sketch out their basic principle of operation in 1905. His starting point was a simple analogy: If matter is lumpy—that is, if every substance in the universe consists of atoms and molecules—then surely light must be lumpy as well.

  • Einstein turned this insight into an equation that described the jittering mathematically. His Brownian motion paper is widely recognized as the first incontrovertible proof that atoms and molecules really exist—and it still serves as the basis for some stock market forecasts.
  • He was trying to explain an odd fact that was first noticed by English botanist Robert Brown in 1827. Brown looked through his microscope and saw that the dust grains in a droplet of water were jittering around aimlessly. This Brownian motion, as it was first dubbed, had nothing to do with the grains being alive, so what kept them moving?
  • If you’ve been to a conference or played with a cat, chances are you’ve seen a laser pointer in action. In the nearly six decades since physicists demonstrated the first laboratory prototype of a laser in 1960, the devices have come to occupy almost every niche imaginable, from barcode readers to systems for hair removal.
  • So Einstein made an inspired guess: Maybe photons like to march in step, so that the presence of a bunch of them going in the same direction will increase the probability of a high-energy atom emitting another photon in that direction. He called this process stimulated emission, and when he included it in his equations, his calculations fit the observations perfectly
  • A laser is just a gadget for harnessing this phenomenon

Opinion | Noam Chomsky: The False Promise of ChatGPT - The New York Times - 0 views

  • we fear that the most popular and fashionable strain of A.I. — machine learning — will degrade our science and debase our ethics by incorporating into our technology a fundamentally flawed conception of language and knowledge.
  • OpenAI’s ChatGPT, Google’s Bard and Microsoft’s Sydney are marvels of machine learning. Roughly speaking, they take huge amounts of data, search for patterns in it and become increasingly proficient at generating statistically probable outputs — such as seemingly humanlike language and thought

  • , we know from the science of linguistics and the philosophy of knowledge that they differ profoundly from how humans reason and use language. These differences place significant limitations on what these programs can do, encoding them with ineradicable defects.
  • It is at once comic and tragic, as Borges might have noted, that so much money and attention should be concentrated on so little a thing — something so trivial when contrasted with the human mind, which by dint of language, in the words of Wilhelm von Humboldt, can make “infinite use of finite means,” creating ideas and theories with universal reach.
  • The human mind is not, like ChatGPT and its ilk, a lumbering statistical engine for pattern matching, gorging on hundreds of terabytes of data and extrapolating the most likely conversational response or most probable answer to a scientific question
  • the human mind is a surprisingly efficient and even elegant system that operates with small amounts of information; it seeks not to infer brute correlations among data points but to create explanations
  • such programs are stuck in a prehuman or nonhuman phase of cognitive evolution. Their deepest flaw is the absence of the most critical capacity of any intelligence: to say not only what is the case, what was the case and what will be the case — that’s description and prediction — but also what is not the case and what could and could not be the case
  • Those are the ingredients of explanation, the mark of true intelligence.
  • Here’s an example. Suppose you are holding an apple in your hand. Now you let the apple go. You observe the result and say, “The apple falls.” That is a description. A prediction might have been the statement “The apple will fall if I open my hand.”
  • an explanation is something more: It includes not only descriptions and predictions but also counterfactual conjectures like “Any such object would fall,” plus the additional clause “because of the force of gravity” or “because of the curvature of space-time” or whatever. That is a causal explanation: “The apple would not have fallen but for the force of gravity.” That is thinking.
  • The crux of machine learning is description and prediction; it does not posit any causal mechanisms or physical laws
  • any human-style explanation is not necessarily correct; we are fallible. But this is part of what it means to think: To be right, it must be possible to be wrong. Intelligence consists not only of creative conjectures but also of creative criticism. Human-style thought is based on possible explanations and error correction, a process that gradually limits what possibilities can be rationally considered.
  • ChatGPT and similar programs are, by design, unlimited in what they can “learn” (which is to say, memorize); they are incapable of distinguishing the possible from the impossible.
  • Whereas humans are limited in the kinds of explanations we can rationally conjecture, machine learning systems can learn both that the earth is flat and that the earth is round. They trade merely in probabilities that change over time.
  • For this reason, the predictions of machine learning systems will always be superficial and dubious.
  • some machine learning enthusiasts seem to be proud that their creations can generate correct “scientific” predictions (say, about the motion of physical bodies) without making use of explanations (involving, say, Newton’s laws of motion and universal gravitation). But this kind of prediction, even when successful, is pseudoscienc
  • While scientists certainly seek theories that have a high degree of empirical corroboration, as the philosopher Karl Popper noted, “we do not seek highly probable theories but explanations; that is to say, powerful and highly improbable theories.”
  • The theory that apples fall to earth because mass bends space-time (Einstein’s view) is highly improbable, but it actually tells you why they fall. True intelligence is demonstrated in the ability to think and express improbable but insightful things.
  • This means constraining the otherwise limitless creativity of our minds with a set of ethical principles that determines what ought and ought not to be (and of course subjecting those principles themselves to creative criticism)
  • True intelligence is also capable of moral thinking
  • To be useful, ChatGPT must be empowered to generate novel-looking output; to be acceptable to most of its users, it must steer clear of morally objectionable content
  • In 2016, for example, Microsoft’s Tay chatbot (a precursor to ChatGPT) flooded the internet with misogynistic and racist content, having been polluted by online trolls who filled it with offensive training data. How to solve the problem in the future? In the absence of a capacity to reason from moral principles, ChatGPT was crudely restricted by its programmers from contributing anything novel to controversial — that is, important — discussions. It sacrificed creativity for a kind of amorality.
  • Here, ChatGPT exhibits something like the banality of evil: plagiarism and apathy and obviation. It summarizes the standard arguments in the literature by a kind of super-autocomplete, refuses to take a stand on anything, pleads not merely ignorance but lack of intelligence and ultimately offers a “just following orders” defense, shifting responsibility to its creators.
  • In short, ChatGPT and its brethren are constitutionally unable to balance creativity with constraint. They either overgenerate (producing both truths and falsehoods, endorsing ethical and unethical decisions alike) or undergenerate (exhibiting noncommitment to any decisions and indifference to consequences). Given the amorality, faux science and linguistic incompetence of these systems, we can only laugh or cry at their popularity.
