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.

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)

What makes ethical accounts natural law ethical is, I argue, commonly misrepresented in teaching within much of the philosophical academy. Yet those immersed in the field of natural law and ethics rarely give definitions/brief characterisations of what makes ethical accounts natural law ethical. I suggest theoretical reasons for the lack. I argue that bringing natural law into ethics is best understood as leading to theoretically unitary accounts, not simply collections of positions detachable from each other: an overlooked and significant point (...) when defending natural law ethical accounts. My arguments throughout rely on the metaethical/normative ethical distinction, which is relatively little used in the natural law literature. I argue that the distinction helps clarify what is distinctive of natural law ethical accounts in general, especially to the secular contemporary philosophical academy, where appreciation of natural law ethical accounts is commonly appreciably lower than in philosophical contexts with a religious ethos.

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.

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)

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.

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)

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].

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.

I give an informal outline of the hole argument which shows that spacetime substantivalism leads to an undesirable indeterminism in a broad class of spacetime theories. This form of the argument depends on the selection of differentiable manifolds within a spacetime theory as representing spacetime. I consider the conditions under which the argument can be extended to address versions of spacetime substantivalism which select these differentiable manifolds plus some further structure to represent spacetime. Finally, I respond to the criticisms of (...) Tim Maudlin and Jeremy Butterfield. (shrink)

Thought experiments are ordinary argumentation disguised in a vivid pictorial or narrative form. This account of their nature will allow me to show that empiricism has nothing to fear from thought experiments. They perform no epistemic magic. In so far as they tell us about the world, thought experiments draw upon what we already know of it, either explicitly or tacitly; they then transform that knowledge by disguised argumentation. They can do nothing more epistemically than can argumentation. I defend my (...) account of thought experiments in Section 3 by urging that the epistemic reach of thought experiments turns out to coincide with that of argumentation and that this coincidence is best explained by the simple view that thought experiments just are arguments. Thought experiments can err—-a fact to be displayed by the thought experiment - anti thought experiment pairs of Section 2. Nonetheless thought experiments can be used reliably and, I urge in Section 4., this is only possible if they are governed by some very generalized logic. I will suggest on evolutionary considerations that their logics are most likely the familiar logics of induction and deduction, recovering the view that thought experiment is argumentation. Finally in Section 5 I defend this argument based epistemology of thought experiments against competing accounts. I suggest that these other accounts can offer a viable epistemology only insofar as they already incorporate the notion that thought experimentation is governed by a logic, possibly of very generalized form.

The epistemic state of complete ignorance is not a probability distribution. In it, we assign the same, unique, ignorance degree of belief to any contingent outcome and each of its contingent, disjunctive parts. That this is the appropriate way to represent complete ignorance is established by two instruments, each individually strong enough to identify this state. They are the principle of indifference (PI) and the notion that ignorance is invariant under certain redescriptions of the outcome space, here developed into the (...) ‘principle of invariance of ignorance' (PII). Both instruments are so innocuous as almost to be platitudes. Yet the literature in probabilistic epistemology has misdiagnosed them as paradoxical or defective since they generate inconsistencies when conjoined with the assumption that an epistemic state must be a probability distribution. To underscore the need to drop this assumption, I express PII in its most defensible form as relating symmetric descriptions and show that paradoxes still arise if we assume the ignorance state to be a probability distribution. *Received February 2007; revised July 2007. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, Pittsburgh, PA 15260; e-mail: [email protected].

Preface: This volume originated in a conference on "The Place of Thought Experiments in Science and Philosophy" which was organized by us and held at the Center for Philosophy of Science at the University of Pittsburgh, April 18-20, 1986. The idea behind this conference was to encourage philosophers and scientists to talk to each other about the role of thought experiments in their various disciplines. These papers were either written for the conference, or were written after it by commentators and (...) other participants.... We hope that this volume will be of use to other philosophers and scientists who are interested in thought experiments, as well as inspire more work in this area.... (shrink)

Thought experiments in science are merely picturesque argumentation. I support this view in various ways, including the claim that it follows from the fact that thought experiments can err but can still be used reliably. The view is defended against alternatives proposed by my cosymposiasts.

According to the underdetermination thesis, all evidence necessarily underdetermines any scientific theory. Thus it is often argued that our agreement on the content of mature scientific theories must be due to social and other factors. Drawing on a long standing tradition of criticism, I shall argue that the underdetermination thesis is little more than speculation based on an impoverished account of induction. A more careful look at accounts of induction does not support an assured underdetermination or the holism usually associated (...) with it. I also urge that the display of observationally equivalent theories is a self-defeating strategy for supporting the underdetermination thesis. The very fact that observational equivalence can be demonstrated by arguments brief enough to be included in a journal article means that we cannot preclude the possibility that the theories are merely variant formulations of the same theory.

Constructivists, such as Harvey Brown, urge that the geometries of Newtonian and special relativistic spacetimes result from the properties of matter. Whatever this may mean, it commits constructivists to the claim that these spacetime geometries can be inferred from the properties of matter without recourse to spatiotemporal presumptions or with few of them. I argue that the construction project only succeeds if constructivists antecedently presume the essential commitments of a realist conception of spacetime. These commitments can be avoided only by (...) adopting an extreme form of operationalism. (shrink)

In a material theory of induction, inductive inferences are warranted by facts that prevail locally. This approach, it is urged, is preferable to formal theories of induction in which the good inductive inferences are delineated as those conforming to some universal schema. An inductive inference problem concerning indeterministic, non-probabilistic systems in physics is posed and it is argued that Bayesians cannot responsibly analyze it, thereby demonstrating that the probability calculus is not the universal logic of induction.

Thought experiments in science are merely picturesque argumentation. I support this view in various ways, including the claim that it follows from the fact that thought experiments can err but can still be used reliably. The view is defended against alternatives proposed by my cosymposiasts.

Bayesian probabilistic explication of inductive inference conflates neutrality of supporting evidence for some hypothesis H (“not supporting H”) with disfavoring evidence (“supporting not-H”). This expressive inadequacy leads to spurious results that are artifacts of a poor choice of inductive logic. I illustrate how such artifacts have arisen in simple inductive inferences in cosmology. In the inductive disjunctive fallacy, neutral support for many possibilities is spuriously converted into strong support for their disjunction. The Bayesian “doomsday argument” is shown to rely entirely (...) on a similar artifact, for the result disappears in a reanalysis that employs fragments of inductive logic able to represent evidential neutrality. Finally, the mere supposition of a multiverse is not yet enough to warrant the introduction of probabilities without some factual analog of a randomizer over the multiverses. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 195-197 [Access article in PDF] Fourth Conference of the European Network of Buddhist-Christian Studies John D'Arcy May Irish School of Ecumenics, Trinity College Dublin Hosted by the Department of Theology at the University of Lund, May 4-7, 2001, this conference reversed the perspective of the previous one, which studied Buddhist perceptions of Jesus. In the event, a strong Buddhist presence from Europe, Thailand, and (...) Japan ensured that distinctive, even conflicting Buddhist views of Christianity were represented at the Lund conference. But there were also some impressive attempts by Christians to come to terms with the history of the relationship and its implications for theology.A feature of the conference was personal testimonies to lives transformed by awareness of other traditions. Eshin Nishimura described his "Zen way—with Christians," starting with his contacts with Quakers in postwar Japan and America. In an extremely interesting and controversial session, Sulak Sivaraksa of Thailand and Reimyo Tierelinckx, a Belgian living the life of a Zen nun in Dortmund, Germany, disagreed about those aspects of Christianity that are actually relevant to Buddhism: social action or contemplation? In his Christian response, Jacques Scheuer emphasized the "always already, always now" character of grace and the eschatological perspective of "Christ ahead of us" as a fundamental contrast, while Asa Egner pointed out the difference between salvation without self-interest and the "god" of capitalism.There were also examples of how Buddhism is understood by Christians in specific contexts. Sulak Sivaraksa recalled the intolerance of the missionaries in Thailand, who assumed they had a monopoly on truth and morality and were "not comfortable with differences." On the other hand, they stimulated renewal in the Theravada sangha and forced Buddhists to confront structural violence. Kosuke Koyama, who was one of those missionaries, said he became more relaxed about living in space-time as the coordinates of divine-human encounter, but questioned whether dependent coorigination and the Buddhist emphasis on psychology leave enough room for a sense of history. Yet Buddhism too requires that we make an effort to "put out the fire," which in today's context should lead to a hermeneutic of ethical action. Eshin Nishimura told how Buddhism, even before it reached Japan, had begun to conceive of the Buddha as an absolute being transcending time and space who was to be worshipped as a savior. He startled participants by speaking of "the secret reason why [End Page 195] Japanese Buddhism is so degenerate," which he later clarified to some extent by illustrating how practice can have priority over charity.Though there was plenty of opportunity to practice at the conference, the personal side was complemented by a number of first-rate scholarly studies of both history and theology/buddhology. Elizabeth Harris drew on her firsthand knowledge of Sri Lanka to analyze the different phases the Christian understanding of Buddhism passed through there. In the period 1800-1830 there was puzzlement among the British as to whether the Buddha was a god or a man who proposed a "system of undisguised atheism." Between 1830 and 1870, though the realization was dawning that Buddhism represented a high degree of ethics and even holiness, the missionaries did everything in their power to undermine it and demonstrate its inferiority and inauthenticity. From 1870 to 1900 this trend continued, despite a growing sympathy for the Buddha and Buddhism on the part of humanists and scholars. The outcome was a "demythologizing" of the Buddha to a status below that of Jesus as the prelude to the growth of conservative evangelical Christianity in Sri Lanka.Hakan Eilert gave a reassessment of Karl Reichelt, the Norwegian Lutheran missionary to China, where he arrived in 1893 after having a healing experience of nature mysticism. This made him more open to Daoism, Confucianism, and Buddhism than might have been expected of a Lutheran from such a conservative background. Though his motto was "the light of the Buddha shines everywhere," in fact he seems to have read Christian ideas into Buddhism. Constrained by incipient Barthianism and a watchful home church, Reichelt... (shrink)

While there is no universal logic of induction, the probability calculus succeeds as a logic of induction in many contexts through its use of several notions concerning inductive inference. They include Addition, through which low probabilities represent disbelief as opposed to ignorance; and Bayes property, which commits the calculus to a ‘refute and rescale’ dynamics for incorporating new evidence. These notions are independent and it is urged that they be employed selectively according to needs of the problem at hand. It (...) is shown that neither is adapted to inductive inference concerning some indeterministic systems. (shrink)

Standard descriptions of thermodynamically reversible processes attribute contradictory properties to them: they are in equilibrium yet still change their state. Or they are comprised of non-equilibrium states that are so close to equilibrium that the difference does not matter. One cannot have states that both change and no not change at the same time. In place of this internally contradictory characterization, the term “thermodynamically reversible process” is here construed as a label for a set of real processes of change involving (...) only non-equilibrium states. The properties usually attributed to a thermodynamically reversible process are recovered as the limiting properties of this set. No single process, that is, no system undergoing change, equilibrium or otherwise, carries those limiting properties. The paper concludes with an historical survey of characterizations of thermodynamically reversible processes and a critical analysis of their shortcomings. (shrink)
