This article examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretation evinces a form of nonseparability, something that otherwise might have been thought of as confined to nonclassical physics. Consideration of the differences between this classical nonseparability and quantum nonseparability shows that the nonseparability exhibited by the classical electromagnetism on the holonomy interpretation is closer to separability than might at first appear.

ON BUBER, like other titles in the Wadsworth Philosopher's Series, offers a concise, yet comprehensive, introduction to this philosopher's most important ideas. Presenting the most important insights of well over a hundred seminal philosophers in both the Eastern and Western traditions, the Wadsworth Philosophers Series contains volumes written by scholars noted for their excellence in teaching and for their well-versed comprehension of each featured philosopher's major works and contributions. These titles have proven valuable in a number of ways. Serving as (...) standalone texts when tackling a philosophers' original sources or as helpful resources for focusing philosophy students' engagements with these philosopher's often conceptually daunting works, these titles have also gained extraordinary popularity with a lay readership and quite often serve as "refreshers" for philosophy instructors.

Ogden spent over forty years attempting "to deal... with the whole of the linguistic problem." This study gives his work an enduring quality which is of particular relevance to late twentieth century linguistics.

In addition to purely practical values, cognitive values also figure into scientific deliberations. One way of introducing cognitive values is to consider the cognitive value that accrues to the act of accepting a hypothesis. Although such values may have a role to play, such a role does not exhaust the significance of cognitive values in scientific decision-making. This paper makes a plea for consideration of epistemic value —that is, value attaching to a state of belief—and defends the notion of cognitive (...) epistemic value against some criticisms that have been raised. A stability requirement for epistemic value functions is argued for on the basis of considerations of diachronic coherence. This stability requirement is sufficient to obtain the Value of Learning Theorem, which says that the expected utility of cost-free learning cannot be negative. This holds also for cognitive epistemic values, provided that the stability requirement is met. (shrink)

Andrew Wayne discusses some recent attempts to account, within a Bayesian framework, for the "common methodological adage" that "diverse evidence better confirms a hypothesis than does the same amount of similar evidence". One of the approaches considered by Wayne is that suggested by Howson and Urbach and dubbed the "correlation approach" by Wayne. This approach is, indeed, incomplete, in that it neglects the role of the hypothesis under consideration in determining what diversity in a body of evidence (...) is relevant diversity. In this paper, it is shown how this gap can be filled, resulting in a more satisfactory account of the evidential role of diversity of evidence. In addition, it is argued that Wayne's criticism of the correlation approach does not indicate a serious flaw in the approach. (shrink)

In this chapter, I will discuss what it takes for a dynamical collapse theory to provide a reasonable description of the actual world. I will start with discussions of what is required, in general, of the ontology of a physical theory, and then apply it to the quantum case. One issue of interest is whether a collapse theory can be a quantum state monist theory, adding nothing to the quantum state and changing only its dynamics. Although this was one of (...) the motivations for advancing such theories, its viability has been questioned, and it has been argued that, in order to provide an account of the world, a collapse theory must supplement the quantum state with additional ontology, making such theories more like hidden-variables theories than would first appear. I will make a case for quantum state monism as an adequate ontology, and, indeed, the only sensible ontology for collapse theories. This will involve taking dynamical variables to possess, not sharp values, as in classical physics, but distributions of values. (shrink)

A proof is given, at a greater level of generality than previous 'no-go' theorems, of the impossibility of formulating a modal interpretation that exhibits 'serious' Lorentz invariance at the fundamental level. Particular attention is given to modal interpretations of the type proposed by Bub.

In this paper, a concept of chance is introduced that is compatible with deterministic physical laws, yet does justice to our use of chance-talk in connection with typical games of chance. We take our cue from what Poincaré called "the method of arbitrary functions," and elaborate upon a suggestion made by Savage in connection with this. Comparison is made between this notion of chance, and David Lewis' conception.

Understanding in Epistemology Epistemology is often defined as the theory of knowledge, and talk of propositional knowledge has dominated the bulk of modern literature in epistemology. However, epistemologists have recently started to turn more attention to the epistemic state or states of understanding, asking questions about its nature, relationship … Continue reading Understanding in Epistemology →.

This work addresses corruption in politics and the public services, arguing that corrupt public officials should be exposed, prosecuted and gaoled, just like their colleagues in the private sector. It covers ethical standards in the public service, both state and federal; the practice of government; the relationships between officials; their advisors and the public; the interplay between politics and personal behaviour, and offering explanations as to what can be done about corruption in public service through asking questions like; how does (...) corruption gain a foothold in public affairs?; how can public trust be rebuilt between bureaucrats, the politicians and the people who vote for them?; and how can we improve accoutability over the cover-ups?

When should I change my mind? What can I believe and what must I doubt? In this new "philosophy of good reasons" Wayne C. Booth exposes five dogmas of modernism that have too often inhibited efforts to answer these questions.

This paper discusses two senses in which a hypothesis may be said to unify evidence. One is the ability of the hypothesis to increase the mutual information of a set of evidence statements; the other is the ability of the hypothesis to explain commonalities in observed phenomena by positing a common origin for them. On Bayesian updating, it is only mutual information unification that contributes to the incremental support of a hypothesis by the evidence unified. This poses a challenge for (...) the view that explanation is a confirmatory virtue that contributes to such incremental support; its advocates must ground it in some relevant difference between humans and a Bayesian agent.

Harvey Brown’s Physical Relativity defends a view, the dynamical perspective, on the nature of spacetime that goes beyond the familiar dichotomy of substantivalist/relationist views. A full defense of this view requires attention to the way that our use of spacetime concepts connect with the physical world. Reflection on such matters, I argue, reveals that the dynamical perspective affords the only possible view about the ontological status of spacetime, in that putative rivals fail to express anything, either true or false. I (...) conclude with remarks aimed at clarifying what is and isn’t in dispute with regards to the explanatory priority of spacetime and dynamics, at countering an objection raised by John Norton to views of this sort, and at clarifying the relation between background and effective spacetime structure.

Quantum information theory has given rise to a renewed interest in, and a new perspective on, the old issue of understanding the ways in which quantum mechanics differs from classical mechanics. The task of distinguishing between quantum and classical theory is facilitated by neutral frameworks that embrace both classical and quantum theory. In this paper, I discuss two approaches to this endeavour, the algebraic approach, and the convex set approach, with an eye to the strengths of each, and the relations (...) between the two. I end with a discussion of one particular model, the toy theory devised by Rob Spekkens, which, with minor modifications, fits neatly within the convex sets framework, and which displays in an elegant manner some of the similarities and differences between classical and quantum theories. The conclusion suggested by this investigation is that Schrödinger was right to find the essential difference between classical and quantum theory in their handling of composite systems, though Schrödinger's contention that it is entanglement that is the distinctive feature of quantum mechanics needs to be modified.

If some sort of dynamical collapse theory is correct, what might the world be like? Can a theory of that sort be a quantum state monist theory, or must such theories supplement the quantum state ontology with additional beables? In a previous work, I defended quantum state monism, with a distributional ontology along the lines advocated by Philip Pearle. In this chapter the account is extended to collapse theories in relativistic spacetimes.

This dissertation is an investigation into the degree to which the mathematics used in physical theories can be constructivized. The techniques of recursive function theory and classical logic are used to separate out the algorithmic content of mathematical theories rather than attempting to reformulate them in terms of "intuitionistic" logic. The guiding question is: are there experimentally testable predictions in physics which are not computable from the data? ;The nature of Church's thesis, that the class of effectively calculable functions on (...) the natural numbers is identical to the class of general recursive functions, is discussed. It is argued that this thesis is an example of an explication of the very notion of an effectively calculable function. This is contrary to a view of the thesis as a hypothesis about the limitations of the human mind. ;The extension to functions of a real variable of the notion of effective calculability is discussed, and it is argued that a function of a real variable must be continuous in order to be considered effectively calculable . The relation between continuity and computability is significant for the problem at hand. The results of a well-designed experiment do not depend critically upon the precise values of the relevant parameters. Accordingly, if the solution to a problem in mathematical physics depends discontinuously upon the data, it cannot be regarded as an experimentally testable prediction of the theory. The principle that the testable predictions of a physical theory cannot be singular is known as the principle of regularity. This principle is significant, because discontinuities generate non-computability, but they also disqualify a prediction from being experimentally testable. ;A mathematical framework is set up for discussing computability in physical theories. This framework is then applied to the case of quantum mechanics. It is found that, due to the use of unbounded operators in the theory, noncomputable objects appear, but predictions which satisfy the principle of regularity are nevertheless computable functions of the data.

In his autobiography, _My Many Selves,_ Wayne C. Booth is less concerned with his professional achievements---though the book by no means ignores his distinguished career---than with the personal vision that emerges from a long life lived thoughtfully. For Booth, even the autobiographical process becomes part of a quest to harmonize the diverse, often conflicting aspects of who he was. To see himself clearly and whole, he broke the self down, personified the fragments, uncovered their roots in his experience and (...) background, and engaged those selves and experiences in dialogue. Basic to his story and to its lifelong concern with ethics and rhetoric was his Mormon youth in rural Utah. In adulthood he struggled with that background, abandoning most Mormon doctrines, but he retained the identity, ethical questions, and concern with communication that this upbringing gave him. The uncommon wisdom and careful attention that empower Wayne Booth's many other books cause _My Many Selves_ to transcend its genre, as the best memoirs always do. The book becomes a window through which we who read it will see our own conflicts, our own ongoing struggle to live honestly and ethically in the world. Wayne Booth died in October 2005, soon after completing work on this autobiography. (shrink)

The central claim of this book is that, early and late, Wittgenstein modelled his approach to existential meaning on his account of linguistic meaning. A reading of Nietzsche’s The Birth of Tragedy sets up Bearn’s reading of the existential point of Wittgenstein’s Tractatus. Bearn argues that both books try to resolve our anxiety about the meaning of life by appeal to the deep, unutterable essence of the world. Bearn argues that as Wittgenstein’s and Nietzsche’s thought matured, they both separately came (...) to believe that the answer to our existential anxiety does not lie beneath the surfaces of our lives, but in our acceptance—Nietzsche’s “Yes”—of the groundless details of those surfaces themselves: the wonder of the ordinary.

Because my paper was often metaphorical, some participants on the symposium expressed puzzlement about my literal meaning, especially about the passage from Mailer. Here are ten literal "theses" that the paper either argues for, implies, or depends on.1. What metaphor is can never be determined with a single answer. Because the word has now become subject to all of the ambiguities of our notions about similarity and difference, the irreducible plurality of philosophical views of how similarities and differences relate will (...) always produce conflicting definitions that will in turn produce different borderlines between what is metaphor and what is not. We thus need taxonomies, not frozen single definitions, of this "essentially contested concept.". (shrink)

The first edition of The Rhetoric of Fiction transformed the criticism of fiction and soon became a classic in the field. One of the most widely used texts in fiction courses, it is a standard reference point in advanced discussions of how fictional form works, how authors make novels accessible, and how readers recreate texts, and its concepts and terms—such as "the implied author," "the postulated reader," and "the unreliable narrator"—have become part of the standard critical lexicon. For this new (...) edition, Wayne C. Booth has written an extensive Afterword in which he clarifies misunderstandings, corrects what he now views as errors, and sets forth his own recent thinking about the rhetoric of fiction. The other new feature is a Supplementary Bibliography, prepared by James Phelan in consultation with the author, which lists the important critical works of the past twenty years—two decades that Booth describes as "the richest in the history of the subject.".

A Bayesian account of the virtue of unification is given. On this account, the ability of a theory to unify disparate phenomena consists in the ability of the theory to render such phenomena informationally relevant to each other. It is shown that such ability contributes to the evidential support of the theory, and hence that preference for theories that unify the phenomena need not, on a Bayesian account, be built into the prior probabilities of theories.

What I am calling for is not as radically new as it may sound to ears that are still tuned to positivist frequencies. A very large part of what we value as our cultural monuments can be thought of as metaphoric criticism of metaphor and the characters who make them. The point is perhaps most easily made about the major philosophies. Stephen Pepper has argued, in World Hypotheses,1 that the great philosophies all depend on one of the four "root metaphors," (...) formism, mechanism, organicism, and contextualism, and they are great precisely because they have so far survived the criticism of rival metaphors. Each view of the totality of things claims supremacy, but none has been able to annihilate the others. They all thus survive as still plausible, pending further criticism through further philosophical inquiry. In this view, even the great would-be literalists like Hobbes and Locke are finally metaphorists—simply committed to another kind of metaphor, one that to them seems literal. Without grossly oversimplifying we could say that the whole work of each philosopher amounts to an elaborate critique of the inadequacy of all other philosophers' metaphors. What is more, the very existence of a tradition of a small group of great philosophies is a sign that hundreds of lesser metaphors for the life of mankind have been tested in the great philosophical—that is, critical—wars and found wanting. · 1.

In a recent paper, David Albert has suggested that no quantum theory can yield a description of the world unfolding in Minkowski spacetime. This conclusion is premature; a natural extension of Stein's notion of becoming in Minkowski spacetime to accommodate the demands of quantum nonseparability yields such an account, an account that is in accord with a proposal which was made by Aharonov and Albert but which is dismissed by Albert as a ‘mere trick’. The nature of such an account (...) is clarified by an extension to a relativistic quantum context of David Lewis' picture of objective chances evolving in time. 1 Introduction 2 Classical relativistic becoming 3 Relativistic quantum becoming, without collapse 4 Relativistic quantum becoming, with collapse 5 Objective chance, conditional probability, and definite properties 6 The nature of the wave function 7 Conclusion.

Once an experiment is done, the observations have been made and the data have been analyzed, what should scientists communicate to the world at large, and how should they do it? This, I will argue, is an intricate question, and one that philosophers can make a contribution to. I will illustrate these points by reference to the debate between Fisher and Neyman & Pearson in the 1950s, which I take to be, at heart, a debate about norms of scientific communication. (...) I will argue that scientists need a richer set of tools for communicating epistemic states that may be very nuanced, and will point to way in which philosophers can contribute. (shrink)

In _The Company We Keep_, Wayne C. Booth argues for the relocation of ethics to the center of our engagement with literature. But the questions he asks are not confined to morality. Returning ethics to its root sense, Booth proposes that the ethical critic will be interested in any effect on the ethos, the total character or quality of tellers and listeners. Ethical criticism will risk talking about the quality of _this_ particular encounter with _this_ particular work. Yet it (...) will give up the old hope for definitive judgments of "good" work and "bad." Rather it will be a conversation about _many_ kinds of personal and social goods that fictions can serve or destroy. While not ignoring the consequences for conduct of engaging with powerful stories, it will attend to that more immediate topic, What happens to us _as we read_? Who am I, _during the hours of reading or listening_? What is the quality of the life I lead in the company of these would-be friends? Through a wide variety of periods and genres and scores of particular works, Booth pursues various metaphors for such engagements: "friendship with books," "the exchange of gifts," "the colonizing of worlds," "the constitution of commonwealths." He concludes with extended explorations of the ethical powers and potential dangers of works by Rabelais, D. H. Lawrence, Jane Austen, and Mark Twain. (shrink)

There seems to be a growing consensus that any interpretation of quantum mechanics other than an instrumentalist interpretation will have to abandon the requirement of Lorentz invariance, at least at the fundamental level, preserving at best Lorentz invariance of phenomena. In particular, it is often said that the collapse postulate is incompatible with the demands of relativity. It is the purpose of this paper to argue that such a conclusion is premature, and to defend the view that a covariant account (...) of collapse can be given according to which the state histories yielded by different reference frames are the Lorentz transforms of each other. Objections that have been raised to such a view are considered. (shrink)

As has been noted by several authors, in a relativistic context, there is an interesting difference between classical and quantum state evolution. For a classical system, a state history of a quantum system given along one foliation uniquely determines, without any consideration of the system’s dynamics, a state history along any other foliation. This is not true for quantum state evolution; there are cases in which a state history along one foliation is compatible with multiple distinct state histories along some (...) other, a phenomenon that David Albert has dubbed “non-narratability.” In this article, we address the question of whether non-narratability is restricted to the sorts of special states that so far have been used to illustrate it. The results of the investigation suggest that there has been a misplaced emphasis on underdetermination of state histories; though this is generic for the special cases that have up until now been considered, involving bipartite systems in pure entangled states, it fails generically in cases in which more component systems are taken into account, and for bipartite systems that have some entanglement with their environment. For such cases, if we impose relativistic causality constraints on the evolution, then, except for very special states, a state history along one foliation uniquely determines a state history along any other. But this in itself is a marked difference between classical and quantum state evolution, because, in a classical setting, no considerations of dynamics at all are needed to go from a state history along one foliation to a state history along another.

A shift in focus, of the sort recently advocated by David Wallace, towards consideration of work in nonequilibrium statistical mechanics has the potential for far-reaching consequences in the way we think about the foundations of statistical mechanics. In particular, consideration of the approach to equilibrium helps to pick out appropriate equilibrium measures, measures that are picked out by the dynamics as "natural' measures for systems in equilibrium. Consideration of the rationale for using such measures reveals that the scope of their (...) legitimate employment is much more limited than an appeal to a Principle of Indifference would suggest. These points are illustrated by use of a toy model that I call the parabola gadget. (shrink)

Beyond Chance and Credence introduces a new way of thinking of probabilities in science that combines physical and epistemic considerations. Myrvold shows that conceiving of probabilities in this way solves puzzles associated with the use of probability and statistical mechanics.

This essay argues for a convergence between, on the one side, Foucault’s characterization of the care of the self as a way of overcoming the traps of anthropological sleep, and on the other side, Deleuze’s characterization of initiating becomings as a way of fleeing the traps of organization, a line of flight, becoming becoming. This convergence is defended on the basis of a Bergsonian ontology of becoming, and in particular, Bergson’s opposition to what he calls the retrograde motion of truth. (...) One result of this convergence is that a Wittgensteinian approach to the sense of life floats to the surface. A kind of mysticism. (shrink)

The Reeh-Schlieder theorem asserts the vacuum and certain other states to be spacelike superentangled relative to local quantum fields. This motivates an inquiry into the physical status of various concepts of localization. It is argued that a covariant generalization of Newton-Wigner localization is a physically illuminating concept. When analyzed in terms of nonlocally covariant quantum fields, creating and annihilating quanta in Newton-Wigner localized states, the vacuum is seen to not possess the spacelike superentanglement that the Reeh-Schlieder theorem displays relative to (...) local fields, and to be locally empty as well as globally empty. Newton-Wigner localization is then shown to be physically interpretable in terms of a covariant generalization of the center of energy, the two localizations being identical if the system has no internal angular momentum. Finally, some of the counterintuitive features of Newton-Wigner localization are shown to have close analogues in classical special relativity. (shrink)

Recent literature on Bohm's alternative to mainstream quantum mechanics may create the misleading impression that, except for perfunctory dismissals, the theory was ignored by the physics community in the years immediately following its proposal. As a matter of fact, Einstein, Pauli, and Heisenberg all published criticisms of Bohm's theory, explaining their reasons for not accepting the theory. These criticisms will be discussed and evaluated in this article.

This paper addresses the question of how we should regard the probability distributions introduced into statistical mechanics. It will be argued that it is problematic to take them either as purely subjective credences, or as objective chances. I will propose a third alternative: they are "almost objective" probabilities, or "epistemic chances". The definition of such probabilities involves an interweaving of epistemic and physical considerations, and so cannot be classified as either purely subjective or purely objective. This conception, it will be (...) argued, resolves some of the puzzles associated with statistical mechanical probabilities; it explains how probabilistic posits introduced on the basis of incomplete knowledge can yield testable predictions, and it also bypasses the problem of disastrous retrodictions, that is, the fact the standard equilibrium measures yield high probability of the system being in equilibrium in the recent past, even when we know otherwise. As the problem does not arise on the conception of probabilities considered here, there is no need to invoke a Past Hypothesis as a special posit to avoid it. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Effecting AffectionThe Corporeal Ethics of Gins and ArakawaGordon C. F. Bearn (bio)No one has yet determined what the body can do …—Spinoza, Ethics, 1677, Part III, proposition 2, ScholiumWhat could be the educational relevance of an architecture designed to make its inhabitants live forever? At first, it is hard to take seriously that Madeline Gins and Arakawa, in their work Architectural Body, are trying to escape mortality. Many are (...) those who smile and say that what they call "the architectural surrounds" that they have designed and built for what they call "organisms that person" are intriguing enough, but this idea of slipping death's grip… Really. They say. Hmmm. And they clear their throats. But is it really that unusual to think that what inspires philosophical thinking is death? And insofar as death has inspired philosophy, hasn't it inspired escape—and if not escape from death itself then at least escape from its terrors? Plato's Phaedo is an early instance of this, and Wittgenstein's Tractatus is a more recent one, no less explicit in its discussion of death. Gins and Arakawa are therefore part of a long and traditional line of philosophers who's thinking never quite loses sight of death. But why are philosophers concerned with death?The reason is simple. By and large, philosophers don't like it here. They would rather be somewhere else. And what don't they like about it here? Often, almost invariably, it is becoming that bothers them. Becoming. And they don't like becoming both for existential and metaphysical reasons. Existentially, "becoming" means change. Today's friends may betray you tomorrow, or the next day. And even if they don't, they will die. And be gone. You too. Soon enough. Dead. Existentially, change and becoming ruin everything we care about—people and projects. Metaphysically, "becoming" is a threat to the dream of understanding, the dream of forming a precise [End Page 40] picture of the world. I learned this from the opening pages of Deleuze's Logic of Sense. On top of the cake, beautifully marked in currants, are the words "EAT ME," and Alice did. She ate the cake and grew taller. And what, you may wonder, is the problem with that? It happens at children's parties every day, even after eating normal cake.Common sense assumes that at any moment Alice will be a certain height, and that as the moments pass her height will increase. But this is just as if we had taken an egg-slicer to her becoming taller, turning becoming into a succession of unchanging slices of being. This egg-sliced reality is good enough for ordinary work, and it is good enough, by means of the calculus, for science and for physics. But it is not good enough for metaphysics. If at a given moment Alice is really becoming taller, then at that moment, while she is becoming, she must paradoxically be both a definite height h, and also not h. If there is becoming, then the world cannot be completely conceptually represented. And if everything is becoming, then nothing can be conceptually represented. That is the metaphysical difficulty with becoming, and so philosophers run from becoming. They run both from death and from what is beyond representation.They tend to go in either of two directions. Up or down. Either up to eternity if you are drawn to the transcendent, or down to the rough ground, the earth, if you are drawn to the ordinary. In either case, the negation implicit in becoming, whether it is the negation of life or the negation of our dreams of conceptual representation, both of these negations are themselves negated. It is the old philosophical gambit: backing by double negation into an ersatz affirmation. Gins and Arakawa join neither of these two ways of escaping becoming. But first let us see why these two negations are disappointing.Take the way up first. This is famously the technique of Plato's Phaedo. Worried that your lover or your mother or you yourself is going to die, Plato's Socrates carves out room for the eternity of the form of human... (shrink)

Landauer’s principle is, roughly, the principle that logically irreversible operations cannot be performed without dissipation of energy, with a specified lower bound on that dissipation. Although widely accepted in the literature on the thermodynamics of computation, it has been the subject of considerable dispute in the philosophical literature. Proofs of the principle have been questioned on the grounds of insufficient generality and on the grounds of the assumption, used in the proofs, of the availability of reversible processes at the microscale. (...) The relevance of the principle, should it be true, has also been questioned, as it has been argued that microscale fluctuations entail dissipation that always greatly exceeds the Landauer bound. In this article Landauer’s principle is treated within statistical mechanics, and a proof of the principle is given that neither relies on neglect of fluctuations nor assumes the availability of thermodynamically reversible processes. In addition, it is argued that microscale fluctuations are no obstacle to approximating thermodynamic reversibility, in the appropriate sense, as closely as one would like. (shrink)
