The thesis that observation necessarily fails to determine theory is false in the sense that observation can provide overwhelming evidence for a particular theory or even a hypothesis within the theory. The saga of quantum discontinuity illustrates the power of evidence to determine theory and shows how that power can be underestimated by inadequate caricatures of the evidential case. That quantum discontinuity can save the phenomena of black body radiation is the widely known result, but it leaves open the possibilities (...) of other accounts. That these phenomena, with the aid of minimal assumptions, entail quantum discontinuity is the crucial but now largely forgotten result. It was first demonstrated by Ehrenfest and Poincaré in 1911 and 1912. (shrink)

Are African and African-American Studies, as defined and practiced in the USA, tools of US cultural imperialism? Are discussions of race, racial inequality or racial oppression in other societies, when carried out by North Americans, to be viewed as `brutal ethnocentric intrusions'? These are among the central propositions of a vigorous polemic by two French sociologists, Pierre Bourdieu and Loïc Wacquant, in a 1999 article entitled `On the Cunning of Imperialist Reason'. As proof, Bourdieu and Wacquant call attention to the (...) recent transnational scholarly dialogue regarding race in Brazil and denounce the `imposition' of an `American tradition', `model' and `dichotomy' of race on Brazil. In particular, they attack as `ethnocentric poison' a 1994 monograph by Michael Hanchard on Brazilian `Black Consciousness' movements, Orpheus and Power: The Movimento Negro of Rio de Janeiro and São Paulo, Brazil, 1945-1988. This article dissects Bourdieu and Wacquant's mischaracterization of the current US-Brazilian dialogue on the African diaspora in the New World. It identifies their fundamental missteps and misjudgments, offers a critique of the schematic model of transnational intellectual circulation they offer in the article, and demonstrates their radical misrepresentation of Michael Hanchard's treatment of questions of race, color and nation in Brazil.

We propose that whatever quantity controls the Heisenberg uncertainty relations it should be identified with an effective Planck parameter. With this definition it is not difficult to find examples where the Planck parameter depends on the region under study, varies in time, and even depends on which pair of observables one focuses on. In quantum cosmology the effective Planck parameter depends on the size of the comoving region under study, and so depends on that chosen region and on time. With (...) this criterion, the classical limit is expected, not for regions larger than the Planck length, \, but for those larger than \^{1/3}\), where H is the Hubble parameter. In theories where the cosmological constant is dynamical, it is possible for the latter to remain quantum even in contexts where everything else is deemed classical. These results are derived from standard quantization methods, but we also include more speculative cases where ad hoc Planck parameters scale differently with the length scale under observation. Even more speculatively, we examine the possibility that similar complementary concepts affect thermodynamical variables, such as the temperature and the entropy of a black hole. (shrink)

My purpose in this chapter is to survey some of the principal approaches to inductive inference in the philosophy of science literature. My first concern will be the general principles that underlie the many accounts of induction in this literature. When these accounts are considered in isolation, as is more commonly the case, it is easy to overlook that virtually all accounts depend on one of very few basic principles and that the proliferation of accounts can be understood as efforts (...) to ameliorate the weaknesses of those few principles. In the earlier sections, I will lay out three inductive principles and the families of accounts of induction they engender. In later sections I will review standard problems in the philosophical literature that have supported some pessimism about induction and suggest that their import has been greatly overrated. In the final sections I will return to the proliferation of accounts of induction that frustrates efforts at a final codification. I will suggest that this proliferation appears troublesome only as long as we expect inductive inference to be subsumed under a single formal theory. If we adopt a material theory of induction in which individual inductions are licensed by particular facts that prevail only in local domains, then the proliferation is expected and not problematic.

In Norton(2003), it was urged that the world does not conform at a fundamental level to some robust principle of causality. To defend this view, I now argue that the causal notions and principles of modern physics do not express some universal causal principle, brought to light by discoveries in physics. Rather they merely assert that, according to relativity theory, spacetime has an invariant velocity, that of light; and that theories of matter admit no propagations faster than light.

Albert Einstein read philosophy. It was not an affectation of a celebrity-physicist trying to show his adoring public that he was no mere technician, but a cultured thinker. It was an interest in evidence from the start. In 1902, Einstein was a poorly paid patent examiner in Bern seeking to make a few extra Francs by offering tutorials in physics. Maurice Solovine answered the advertisement. The tutorials quickly vanished when they discovered their common fascinations in reading and talking. They were (...) soon joined in their raucous meetings by Conrad Habicht, completing what they dubbed their “Olympia Academy.” Their explorations where wide-ranging, devouring texts and sausages with gusto. They read the philosophers and philosophically-minded scientists of the day, including Pearson, Mach, Hill, Hume, Spinoza, Avenarius, Cifford and Poincaré. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Whoa! JOHN SHOPTAW ONE A young man with gold hair in a coal-black robe and slippers was off to confront the Sun. But as he paced the hotel corridors, Ray could feel his step losing its jaunt. At this rate, he’d make it to nowhere in nothing flat. Just then, he noticed his old wall map thumbtacked over some double doors. How’d his Boys’ Life get out here? (...) He looked it over, the big fat world, cut open and stretched flat, like an elephant hide. The properties were green, purple and red, and the waters whitish blue. The Mercator-projected bottom was jagged with ice. The whole place was crawling with letters, like ants on a cake. The best part was the creatures: a long-armed squid suctioning a whale, sea lions sunning themselves. No. Seals. He bunched his brows. No. Hills. And game big as states, as nations: hippos in Africa’s watering holes, a beauty of a cheetah, its sights trained. Untacking and folding the map, Ray tucked it into his pocket and slid open the doors. He found himself in a dim cavern facing a motionless escalator. Its stairs were gold-plated, its balustrades brushed aluminum and its handrails hand-rubbed ostrich skin. He could see no end of stairs. It must be arion 27.1 spring/summer 2019 one unbroken flight to the Sun’s penthouse. But where was the down escalator? Beats him. He planted his slippers and clasped the rails. With a little lurch the escalator began its quickening glide. Now this was first-class. No huffing required. Simply the assumption of an attitude. Up ahead, the horizon gleamed ivory. 2 whoa! TWO The stairway teeth clamped shut and Ray was thrown into a hard glare. Sunblock and goggles— they’ll let you look into things—on your right, came a voice positively sunny. Ray slathered and goggled himself, and beheld by a high stone robed in emerald moss a trim figure in a sea-snail-purple sweatsuit and a broad-brimmed straw hat puttering about a humid sundial of wide-waking annuals and perennials— snowdrops, crocuses, daisies and daylilies, rice in flower and maize in silk, woozy jasmine and heady grapevines, a temperamental winter daphne, and tall in the motley midst the polar gnomon, an Indian turnsole or heliotrope, sweeping its shaft of shadow from one to the next minute marigold dot as the ambling photosynthesizer passed the fragrant hours of the zodiac. Batting away hummingbirds and honeybees, Ray waded through the flower bed toward Sol. Am I your heir? Can I have what I want? Sure, kid, name it. Ray glanced toward the honey-scented manure. A joyride? Sol sighed. It’s your funeral. Taking his time, he led Ray out to the dayport. What a letdown! Ray’d expected a futuristic heliumpowered sports coupe, or at least a souped-up solar Mustang. Not this gold-rimmed, pyrite-axled backward half-bucket with footpads! John Shoptaw 3 Dawn, meanwhile, with her practiced blush arched her horizon, and her pomegranate interiors yawned wide. The stars dispersed. Venus, her shell-blue and egg-white gauzes aswirl, gave Dawn a last long look above her handmirror’s crescent rim. Sol was watching moonshine evanesce from his glowing barndoors, which cracked in a spewing welding arc and then opened wide to reveal a dozen prompt and close-cropped Hours, coaxing a team of four mammoth pegasi yoked neck and neck and neck and neck, stoked with thick ambrosial plasma and snorting flame. As the nymphs hitched the tack to the chariot pole, the Sun, shaking his head, untied his flaring sunhat and knotted it under Ray’s chin. Lay off the whip and draw rein with a firm hand. They’ll fly by themselves with no help from you. But they’ll answer to Clover, Crocus, Peony, Sage. Steer clear of the straightaway. Bank the rig into a circumbendibus. But don’t, whatever you do... But Ray’s attention had drifted. The rampant quadrupeds hooved trails of sparks down the dayport door, their heavy fog blankets slid off, and they shook out their shoulder-wings. A pliant breeze sprang up from the East... (shrink)

This paper discusses the chemistry manuscript collection in an institution that does not readily come to mind when searching for unpublished matter on the history of chemistry, the National Library of Medicine in Bethesda, Maryland. This collection includes personal papers of some twentieth-century American chemists and biochemists, lecture notes of British and American chemistry courses of the eighteenth, nineteenth, and twentieth centuries from a variety of institutional settings, and extended oral histories of some major figures in the history of modern (...) chemistry and biochemistry. Among those represented in this collection are Joseph Black, Louis Pasteur, George B. Wood, Donald D. Van Slyke, and Albert Szent-Györgyi. In addition to illustrating the type of resources available, this paper also suggests some specific ways in which the collection can contribute to research in the history of chemistry. (shrink)

The inaugural title in the new, Open Access series BSPS Open, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference. The fundamental burden of a theory of inductive inference is to determine which are the good inductive inferences or relations of inductive support and why it is that they are so. The traditional approach is modeled on that taken in accounts of deductive inference. It seeks universally applicable schemas or rules or a single (...) formal device, such as the probability calculus. After millennia of halting efforts, none of these approaches has been unequivocally successful and debates between approaches persist. The Material Theory of Induction identifies the source of these enduring problems in the assumption taken at the outset: that inductive inference can be accommodated by a single formal account with universal applicability. Instead, it argues that that there is no single, universally applicable formal account. Rather, each domain has an inductive logic native to it. Which that is, and its extent, is determined by the facts prevailing in that domain. Paying close attention to how inductive inference is conducted in science and copiously illustrated with real-world examples, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference.

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle asserts that (...) "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

We evaluate the “story grammar” approach to story understanding from three perspectives. We first examine the formal properties of the grammars and find only one to be formally adequate. We next evaluate the grammars empirically by asking whether they generate all simple stories and whether they generate only stories. We find many stories that they do not generate and one major class of nonstory that they do generate. We also evaluate the grammars' potential as comprehension models and find that they (...) would add nothing to semantic models that focus on the story content. Hence we advocate a story content oriented approach to studying story understanding instead of the structural story grammar approach. (shrink)

An infinite lottery machine is used as a foil for testing the reach of inductive inference, since inferences concerning it require novel extensions of probability. Its use is defensible if there is some sense in which the lottery is physically possible, even if exotic physics is needed. I argue that exotic physics is needed and describe several proposals that fail and at least one that succeeds well enough.

It is proposed that we use the term “approximation” for inexact description of a target system and “idealization” for another system whose properties also provide an inexact description of the target system. Since systems generated by a limiting process can often have quite unexpected, even inconsistent properties, familiar limit systems used in statistical physics can fail to provide idealizations, but are merely approximations. A dominance argument suggests that the limiting idealizations of statistical physics should be demoted to approximations.

Contrary to formal theories of induction, I argue that there are no universal inductive inference schemas. The inductive inferences of science are grounded in matters of fact that hold only in particular domains, so that all inductive inference is local. Some are so localized as to defy familiar characterization. Since inductive inference schemas are underwritten by facts, we can assess and control the inductive risk taken in an induction by investigating the warrant for its underwriting facts. In learning more facts, (...) we extend our inductive reach by supplying more localized inductive inference schemes. Since a material theory no longer separates the factual and schematic parts of an induction, it proves not to be vulnerable to Hume's problem of the justification of induction. (shrink)

While there is general agreement on the need to teach ethics in the MBA classroom, there are great difficulties in completely integrating such material within the confines of an actual MBA program. This paper attempts to address these difficulties by focusing on the teaching of such issues in one particular class — MBA macroeconomics.Ethical dilemmas often arise due to failures of the market place or due to inappropriate assumptions regarding the market model. Thus, specific suggestions are offered in regard to (...) the integration of ethical issues into the traditional macroeconomic curriculum. Suggestions are even offered as how to scale back the basic macro material so that the additional material may be accommodated. (shrink)

Newton’s equations of motion tell us that a mass at rest at the apex of a dome with the shape specified here can spontaneously move. It has been suggested that this indeterminism should be discounted since it draws on an incomplete rendering of Newtonian physics, or it is “unphysical,” or it employs illicit idealizations. I analyze and reject each of these reasons. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, Pittsburgh, PA (...) 15260; e‐mail: [email protected].

I deny that the world is fundamentally causal, deriving the skepticism on non-Humean grounds from our enduring failures to find a contingent, universal principle of causality that holds true of our science. I explain the prevalence and fertility of causal notions in science by arguing that a causal character for many sciences can be recovered, when they are restricted to appropriately hospitable domains. There they conform to a loose collection of causal notions that form a folk science of causation. This (...) recovery of causation exploits the same generative power of reduction relations that allows us to recover gravity as a force from Einstein's general relativity and heat as a conserved fluid, the caloric, from modern thermal physics, when each theory is restricted to appropriate domains. Causes are real in science to the same degree as caloric and gravitational forces. (shrink)

There are many ways of combining three letters out of an alphabet of 26; yet still there are overlaps which can confuse meaning. So the first duty of anyone using an acronym is to say what it denotes. Here, POM is “problem-oriented medicine”, EBM is “evidence-based medicine”, and CPD is “continuous professional development”. These designations, familiar as they are to clinicians, define what is meant by these terms, but fall well short of describing them for the general reader, something which (...) must now be done.Problem-oriented medicine, described and advocated by Lawrence Weed,1 is an approach which elicits and categorises the patient's problems, both those described by him or her and those discovered on physical examination or in the course of investigation. The list of problems, with the action proposed for each, forms the basis of the clinical record. This approach has the great merit of focusing on what is actually troubling the patient, and it includes the important task of listening to what he says. All approaches to difficult matters have their limitations; those of POM include the inarticulacy of some patients, the impatience of some doctors, the accumulation of problems as age advances, and the inelasticity of time.Evidence-based medicine has ….

Context Conflicts over treatment decisions have been linked to physicians' emotional states. Objective To measure the prevalence of emotional exhaustion and conflicts over treatment decisions among US obstetrician/gynaecologists (ob/gyns), and to examine the relationship between the two and the physician characteristics that predict each. Methods Mailed survey of a stratified random sample of 1800 US ob/gyn physicians. Criterion variables were levels of emotional exhaustion and frequency of conflict with colleagues and patients. Predictors included physicians' religious characteristics and self-perceived empathy. Results (...) Response rate among eligible physicians was 66% (1154/1760). 36% of ob/gyns reported high levels of emotional exhaustion, and majorities reported conflict with colleagues (59%) and patients (61%). Those reporting conflict were much more likely to report emotional exhaustion (58% vs 29% who never conflict, OR, 95% CI 2.8, 1.6 to 4.8 for conflict with colleagues; 55% versus 26%, OR, 95% CI 2.2, 1.4 to 3.5 for conflict with patients). Physicians with lower self-perceived empathy were more likely to report physician-patient conflicts (65% vs 58% with higher empathy, OR, 95% CI 1.4, 1.0 to 1.9), as were female ob/gyns (66% vs 57% of males, OR, 95% CI 1.5, 1.1 to 2.0). Foreign-born physicians were less likely to report such conflicts (47% vs 64% of US born, OR, 95% CI 0.5, 0.4 to 0.8). Physicians' religious characteristics were not significantly associated with reporting conflict. Conclusions Conflicts over treatment decisions are associated with physicians' empathy, gender, immigration history and level of emotional exhaustion. With respect to the latter, conflict in the clinical encounter may represent an overlooked source or sign of burnout among ob/gyns. (shrink)

In a formal theory of induction, inductive inferences are licensed by universal schemas. In a material theory of induction, inductive inferences are licensed by facts. With this change in the conception of the nature of induction, I argue that the celebrated “problem of induction” can no longer be set up and is thereby dissolved. Attempts to recreate the problem in the material theory of induction fail. They require relations of inductive support to conform to an unsustainable, hierarchical empiricism.
