Monte Carlo simulations arrive at their results by introducing randomness, sometimes derived from a physical randomizing device. Nonetheless, we argue, they open no new epistemic channels beyond that already employed by traditional simulations: the inference by ordinary argumentation of conclusions from assumptions built into the simulations. We show that Monte Carlo simulations cannot produce knowledge other than by inference, and that they resemble other computer simulations in the manner in which they derive their conclusions. Simple examples of Monte Carlo simulations (...) are analysed to identify the underlying inferences. (shrink)

The history of communication is a new subject in mass communication and journalism curricula, one for which there has been only scattered published research and no adequate text. Communication History attempts to remedy both of these problems by providing a challenging new approach to the study of communication over time. Moving away from a tradition that focuses merely on major communication personalities or institutions, the authors instead encourage the reader to see the interrelated processes by which information in diffused. The (...) authors utilize social science concepts and techniques to enlarge and enrich our understanding of communication in historical perspective. (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.

Pushing past the constraints of postmodernism which cast "reason" and"religion" in opposition, God, the Gift, and Postmodernism, seizes the opportunity to question the authority of "the modern" and open the limits of possible experience, including the call to religious experience, as a new millennium approaches. Jacques Derrida, the father of deconstruction, engages with Jean-Luc Marion and other religious philosophers to entertain questions about intention, givenness, and possibility which reveal the extent to which deconstruction is structured like religion. New interpretations of (...) Kant, Heidegger, Husserl, and Derrida emerge from essays and discussions with distinguished philosophers and theologians from the United States and Europe. The result is that God, the Gift, and Postmodernism elaborates a radical phenomenology that stretches the limits of its possibility and explores areas where philosophy and religion have become increasingly and surprisingly convergent. Contributors include: John D. Caputo, John Dominic Crossan, Jacques Derrida, Robert Dodaro, Richard Kearney, Jean-Luc Marion, Frangoise Meltzer, Michael J. Scanlon, Mark C. Taylor, David Tracy, Merold Westphal and Edith Wyschogrod. (shrink)

I begin this commentary with an expanded typology of theories that endorse an internal morality of medicine. I then subject these theories to a philosophical critique. I argue that the more robust claims for an internal morality fail to establish a stand-alone method for bioethics because they ignore crucial non-medical values, violate norms of justice and fail to establish the normativity of medical values. I then argue that weaker versions of internalism avoid such problems, but at the cost of failing (...) to provide a clear sense in which their moral norms are internal or can ground a comprehensive approach to moral problems. Finally, I explore various functions that an internal morality might serve, concluding with the observation that, while there may be a core of good sense to the notion of an internal morality of medicine, our expectations for it must be drastically lowered.

There can be no mistaking the importance of Caputo's work." —Edith Wyschogrod "No one interested in Derrida, in Caputo, or in the larger question of postmodernism and religion can afford to ignore this pathbreaking study.

There are many good reasons for a merger between bioethics and human rights. First, though, significant philosophical groundwork must be done to clarify what a human right to health would be and—if we accept that it exists—exactly how it might influence the practical decisions we face about who gets what in very different contexts.

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].

The Insistence of God presents the provocative idea that God does not exist, God insists, while God’s existence is a human responsibility, which may or may not happen. For John D. Caputo, God’s existence is haunted by "perhaps," which does not signify indecisiveness but an openness to risk, to the unforeseeable. Perhaps constitutes a theology of what is to come and what we cannot see coming. Responding to current critics of continental philosophy, Caputo explores the materiality of perhaps and (...) the promise of the world. He shows how perhaps can become a new theology of the gaps God opens. (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.

This article begins with some preliminary remarks about the general features and basic varieties of reflective equilibrium in moral reflection. It then considers a couple of preliminary doubts about this method. One of these doubts claims that the most plausible interpretation of RE is so comprehensive that it risks paralyzing our thinking, while the other claims that this same version of RE is insufficiently determinate in practical contexts and will thus fail to be sufficiently action-guiding. The article then explicates the (...) sense in which RE qualifies as a coherence theory of justification, and considers several objections to RE that flow from its reliance on the putative connection between coherence and moral justification.

Most bioethicists and professional medical societies condemn the practice of ?slow codes.? The American College of Physicians ethics manual states, ?Because it is deceptive, physicians or nurses should not perform half-hearted resuscitation efforts (?slow codes?).? A leading textbook calls slow codes ?dishonest, crass dissimulation, and unethical.? A medical sociologist describes them as ?deplorable, dishonest and inconsistent with established ethical principles.? Nevertheless, we believe that slow codes may be appropriate and ethically defensible in situations in which cardiopulmonary resuscitation (CPR) is likely (...) to be ineffective, the family decision makers understand and accept that death is inevitable, and those family members cannot bring themselves to consent or even assent to a do-not-resuscitate (DNR) order. In such cases, we argue, physicians may best serve both the patient and the family by having a carefully ambiguous discussion about end-of-life options and then providing resuscitation efforts that are less vigorous or prolonged than usual.

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)

Participants in AIDS research may justify noncompliance with protocols by a “coercion defense.” While this defense may not be philosophically successful, a prudent social policy can enhance compliance by encouraging community participation and providing greater access to non‐validated therapies.

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.

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)

In Leo Szilard’s 1929 thought experiment, a Maxwell demon manipulates a one-molecule gas to reverse the second law of thermodynamics. The demon must fail, Szilard argued, since there is hidden entropy creation in the demon’s collecting of information. This thought experiment is an inconsistent muddle of improper idealizations. It diverted an already successful literature of exorcism into degenerating speculations about about a connection between thermodynamic entropy and information. These confusions persist today in a voluminous literature. Narrative conventions in a thought (...) experiment allow thought experimenters great latitude in deciding which processes are typical and bear generalization and which can be idealized away as incidental. For its abuse of this latitude and the extent of the harm it caused, this thought experiment merits the distinction of the worst thought experiment in science. (shrink)

At the age of sixteen, Einstein imagined chasing after a beam of light. He later recalled that the thought experiment had played a memorable role in his development of special relativity. Famous as it is, it has proven difficult to understand just how the thought experiment delivers its results. It fails to generate problems for an ether-based electrodynamics. I propose that Einstein’s canonical statement of the thought experiment from his 1946 “Autobiographical Notes,” makes most sense not as an argument against (...) ether-based electrodynamics, but as an argument against “emission” theories of light.

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.

After examining the ways in which Newman employed the tools of rhetoric in his Apologia pro Vita Sua in response to Charles Kingsley’s charges against him, this essay charts Newman’s use of his personal testimony to proclaim the Gospel and defend the Catholic Faith and concludes with an analysis of the strengths and potential weaknesses of his approach.

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.

© 2011 by Oxford University Press. All rights reserved. Results on the observational indistinguishability of spacetimes demonstrate the impossibility of determining by deductive inference which is our spacetime, no matter how extensive a portion of the spacetime is observed. These results do not illustrate an underdetermination of theory by evidence, since they make no decision between competing theories and they make little contact with the inductive considerations that must ground such a decision. Rather, these results express a variety of indeterminism (...) in which a specification of the observable past always fails to fix the remainder of a spacetime. This form of indeterminism is more troubling than the familiar indeterminism of quantum theory. The inductive inferences that can discriminate among the different spacetime extensions of the observed past are here called "opaque," which means that we cannot readily see the warrant that lies behind them.
