Michael Friedman has recently argued that Carnap'sLogical Syntax of Language is fundamentally flawed in a way that reveals the ultimate failure of logical positivism. Friedman's argument depends crucially on two claims: (1) that Carnap was committed to the view that there is a universal metalanguage and (2) that given what Carnap wanted from a metalanguage, in particular given that he wanted a definition of analytic for an object language, he was in fact committed to a hierarchy of stronger and stronger (...) metalanguages. We argue that neither of these claims need be accepted. We show that there is no textual evidence for (1) and that if metalanguages are to be used for merely descriptive and not also justificatory purposes, Carnap does not need to define analyticity sufficiently for proving consistency, and so could have given a definition that does not entail a hierarchy of metalanguages. (shrink)

It is well known that Tarski proved a result which can be stated roughly as: no sufficiently rich, consistent, classical language can contain its own truth definition. Tarski's way around this problem is to deal with two languages at a time, an object language for which we are defining truth and a metalanguage in which the definition occurs. An obvious question then is: under what conditions can we construct a definition of truth for a given object language. Tarski claims that (...) it is necessary and sufficient that the metalanguage be "essentially richer". Our contention, put bluntly, is that this claim deserves more scrutiny from philosophers than it usually gets and in fact is false unless "essentially richer" means nothing else than "sufficient to contain a truth definition for the object language.".

Logical Options introduces the extensions and alternatives to classical logic which are most discussed in the philosophical literature: many-sorted logic, second-order logic, modal logics, intuitionistic logic, three-valued logic, fuzzy logic, and free logic. Each logic is introduced with a brief description of some aspect of its philosophical significance, and wherever possible semantic and proof methods are employed to facilitate comparison of the various systems. The book is designed to be useful for philosophy students and professional philosophers who have learned some (...) classical first-order logic and would like to learn about other logics important to their philosophical work.

We discuss in this paper the question of the scope of the principle of tolerance about languages promoted in Carnap's The Logical Syntax of Language and the nature of the analogy between it and the rudimentary conventionalism purportedly exhibited in the work of Poincaré and Hilbert. We take it more or less for granted that Poincaré and Hilbert do argue for conventionalism. We begin by sketching Coffa's historical account, which suggests that tolerance be interpreted as a conventionalism that allows us (...) complete freedom to select whatever language we wish—an interpretation that generalizes the conventionalism promoted by Poincaré and Hilbert which allows us complete freedom to select whatever axiom system we wish for geometry. We argue that such an interpretation saddles Carnap with a theory of meaning that has unhappy consequences, a theory we believe he did not hold. We suggest that the principle of linguistic tolerance in fact has a more limited scope; but within that scope the analogy between tolerance and geometric conventionalism is quite tight. (shrink)

Graham Solomon, to whom this collection is dedicated, went into hospital for antibiotic treatment of pneumonia in Oc- ber, 2001. Three days later, on Nov. 1, he died of a massive stroke, at the age of 44. Solomon was well liked by those who got the chance to know him—it was a revelation to?nd out, when helping to sort out his a?airs after his death, how many “friends” he had whom he had actually never met, as his (...) email included correspondence with philosophers around the world running sometimes to hundreds of messages. He was well respected in the philosophical community more broadly. He was for several years a member of the editorial board for the Western Ontario Series in Philosophy of Science. While he was employed at Wilfrid Laurier University in Waterloo, Ontario, several of us at the University of Wat- loo always regarded our own department as a sort of second academic home for him. We therefore decided that it would be appropriate to hold a memorial conference in his honour. Thanks to the generous?nancial support of the Humphrey Conference Fund, we were able to do so in May 2003. Many of the papers in this volume were presented at that conf- ence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXVI, Number 1, April 2000, pp. 129-142 Hume on ''Greatness of Soul" GRAHAM SOLOMON The "great-souled man" was first described in detail in Book iv of Aristotle's Nicomachean Ethics. Simon Blackburn concisely summarizes Aristotle's portrait of this "lofty character": "The great-souled man is of a distinguished situation, worthy of great things, 'an extreme in respect of the greatness of his claims, but a mean (...) in respect of the Tightness of them', perfectly virtuous, good at conferring benefits but ashamed of receiving them, neither humble nor vain. The combination involves proper pride or magnanimity." Such men will enter politics with the aim of preserving justice and working for the good of society, or they will exhibit great personal courage in battle, or, more generally, they will aim at virtuous action at all times, even when faced with painful choices and life-threatening circumstances. Historians disagree about whether Aristotle held that the great-souled man is motivated in part by a desire to be admired by others, but certainly he held that the great-souled man was capable of performing great and virtuous actions that would be admired.1 By the mid-eighteenth century, greatness of soul could be found in much less distinguished situations. Consider, for example, Laurence Sterne's Tristram Shandy. Tristram attributes greatness of soul to his mother for wanting to give birth to him under the care of a midwife rather than a doctor. His father thinks that turning down a large purse of money offered in exchange for naming one's son Judas is an act of greatness of mind. And Tristram says his friend Jenny exhibited greatness of soul by purchasing a much less expensive piece of silk than the one she initially wanted, deferring to Tristram's unvoiced but Graham Solomon is at the Philosophy Department,Wilfrid Laurier University,Waterloo, Ontario, Canada N2L 3C5. e-mail: [email protected] 130 Graham Solomon obvious judgment.2 For an example from the nineteenth century, consider the following passage from the novel The Wrecker (1891) by Robert Louis Stevenson and Lloyd Osbourne. The narrator, a wealthy young American, is slumming as a bohemian art student in the Latin Quarter of Paris: "I always looked with awful envy... on a certain countryman of my own, who had a studio in the Rue Monsieur Ie Prince, wore boots, and long hair in a net, and could be seen tramping off, in this guise, to the worst eating-house of the quarter, followed by a Corsican model, his mistress, in the conspicuous costume of her race and calling. It takes some greatness of soul to carry even folly to such heights as these."3 There the character's greatness of soul seems to involve an ability to ignore or overlook or misinterpret the opinions others might have of him. While the phrase "greatness of soul" or "greatness of mind" is not commonly used nowadays,4 the Latin form "magnanimity" is still in use in ordinary, everyday, reasonably educated discourse. And occasionally "highmindedness " is used. The capacity to make magnanimous gestures is still widely felt to be a virtue. "Magnanimity" nowadays refers to a mix of unselfishness, generosity, the capacity to rise above petty feelings of resentment and revenge, and more generally and vaguely to a kind of nobility of heart and mind. These are features that Aristotle would recognize. But, it seems to me, we are prepared to apply the term to a far wider class of people than Aristotle would. Magnanimity is nowadays thought to be a virtue that can be exhibited by almost anyone. The first extended discussion in English-language philosophy of the concept of greatness of soul or mind is in David Hume's Treatise III iii 2, a section titled "Of greatness of mind." Hume's discussion contributed to a domesticated and democratized understanding of the concept, a more serious ancestor of the concept found in Tristram Shandy5 and The Wrecker. Donald Siebert argues in the chapter "In Search of the Hero of Feeling" in The Moral Animus of David Hume6 that after the initial exploration of the concept in the Treatise, Hume eventually settled in The History...

The advent of formal definitions of the simplicity of a theory has important implications for model selection. But what is the best way to define simplicity? Forster and Sober ([1994]) advocate the use of Akaike's Information Criterion (AIC), a non-Bayesian formalisation of the notion of simplicity. This forms an important part of their wider attack on Bayesianism in the philosophy of science. We defend a Bayesian alternative: the simplicity of a theory is to be characterised in terms of Wallace's Minimum (...) Message Length (MML). We show that AIC is inadequate for many statistical problems where MML performs well. Whereas MML is always defined, AIC can be undefined. Whereas MML is not known ever to be statistically inconsistent, AIC can be. Even when defined and consistent, AIC performs worse than MML on small sample sizes. MML is statistically invariant under 1-to-1 re-parametrisation, thus avoiding a common criticism of Bayesian approaches. We also show that MML provides answers to many of Forster's objections to Bayesianism. Hence an important part of the attack on Bayesianism fails. (shrink)

This is a “bottom-up” paper in the sense that it draws lessons in defining disciplinary categories under study from a series of empirical studies of interdisciplinarity. In particular, we are in the process of studying the interchange of research-based knowledge between Cognitive Science and Educational Research. This has posed a set of design decisions that we believe warrant consideration as others study cross-disciplinary research processes.

There are several open problems in the study of the calculi which result from adding either of Hilbert's ϵ- or τ-operators to the first order intuitionistic predicate calculus. This paper provides answers to several of them. In particular, the first complete and sound semantics for these calculi are presented, in both a “quasi-extensional” version which uses choice functions in a straightforward way to interpret the ϵ- or τ-terms, and in a form which does not require extensionality assumptions. Unlike the classical (...) case, the addition of either operator to intuitionistic logic is non-conservative. Several interesting consequences of the addition of each operator are proved. Finally, the independence of several other schemes in either calculus are also proved, making use of the semantics supplied earlier in the paper. (shrink)

An interesting recent reply to the Paradox of Knowability is Neil Tennant's proposal: to restrict the anti-realist's knowability thesis to truths the knowing of which is logically consistent. However, this proposal is egregiously ad hoc unless motivated by something other than the wish to save anti-realism from embarrassment. We examine Tennant's argument that his restriction is motivated by parallel considerations in cases that are neutral with respect to debates about realism. We conclude that the cases are not neutral, nor the (...) considerations parallel. The failure of Tennant's argument provides an opportunity to reflect on, among other things, the nature of Moore's paradox, and the role of idealization in doxastic logic. (shrink)

Though the papers in this volume for the most part address the question, “What is Christian about Christian Bioethics”, this paper addresses instead a closely related question, “How would a Christian approach to bioethics differ from the kind of secular academic bioethics that has emerged as such an important field in the contemporary university?” While it is generally assumed that a secular bioethics rooted in moral philosophy will be more culturally authoritative than an approach to bioethics grounded in the contingent (...) particularities of a religious tradition, I will give reasons for rejecting this assumption. By examining the history of the recent revival of academic bioethics as well as the state of the contemporary moral philosophy on which it is based I will suggest that secular bioethics suffers from many of the same liabilities as a carefully articulated Christian bioethics. At the end of the paper I will turn briefly to examine the question of how, in light of this discussion, a Christian bioethics might best be pursued. (shrink)

M. H. A. Newman (1928) criticized Russell's structuralist philosophy of science. Demopoulos and Friedman have discussed Newman's critique, showing its relevance to the structuralist positions held by Schlick and Carnap, and to Putnam's argument against "metaphysical realism". I discuss Richard Braithwaite's (1940) appeal to Newman in a critique of Arthur Eddington. Braithwaite believed Newman had shown that "structure depends upon content". Eddington, in his reply, misunderstood the generality of Newman's argument.

What's Wrong?: Applied Ethicists and Their Critics is a thorough and engaging introduction to applied ethics that covers virtually all of the issues in the field. Featuring more than ninety-five articles, it addresses standard topics--such as abortion, euthanasia, capital punishment, world hunger, and animal rights--and also delves into cutting-edge areas like cloning, racial profiling, same-sex marriage, prostitution, and slave reparations. The volume includes seminal essays by prominent philosophers (Robert Nozick, James Rachels, Peter Singer, and Judith Jarvis Thomson) alongside work by (...) newer voices in the field. Employing a unique approach to teaching argumentation, editors David Boonin and Graham Oddie unify the wealth of material presented in this collection. Each chapter opens with a featured article that takes a strong stand on a particular issue; the essays that immediately follow offer objections and critical responses to the arguments put forth in the featured selection. This format helps students learn how to better engage in debates because it illustrates how philosophers argue with each other. In addition, a general introduction describes strategies for understanding and evaluating the different types of arguments contained in the readings, while detailed chapter introductions enable students to see precisely how the arguments presented in the various writings are related to one another. Discussion questions and suggestions for further reading are included for each chapter. Ideal for courses in introduction to ethics and applied ethics/contemporary moral problems, What's Wrong? can also be used in critical thinking courses that emphasize philosophical argumentation.

Frege famously claimed that logic is the science of truth: “To discover truths is the task of all science; it falls to logic to discern the laws of truth” (Frege, 1956, p. 289). But just like the other foundational concept of set, truth at that time was intimately associated with paradox; in the case of truth, the Liar paradox. The set-theoretical paradoxes had their teeth drawn by being recognised as reductio proofs of assumptions that had seemed too obvious to warrant (...) stating explicitly, but were now seen to be substantive, and more importantly inconsistent. Tarski includes the Liar paradox in his classic discussion of the concept of truth (Tarski, 1956), and developed it, in the form of his famous theorem on the undefinability of truth, as a reductio of the assumption that a language could be semantically closed, in the sense of being able to contain its own truth-predicate.Frege famously claimed that logic is the science of truth: “To discover truths is the task of all science; it falls to logic to discern the laws of truth” (Frege, 1956, p. 289).

The proposal to create a chamber selected by sortition would extend this democratic procedure into the legislative branch of government. However, there are good reasons to believe that, as currently conceived by John Gastil and Erik Olin Wright, the proposal will fail to realize sufficiently two fundamental democratic goods, namely, political equality and deliberative reasoning. It is argued through analysis of its historic and contemporary application that sortition must be combined with other institutional devices, in particular, rotation of membership and (...) limited mandate, in order to be democratically effective and to realize political equality and deliberative reasoning. An alternative proposal for a responsive sortition legislature is presented as more realistic and utopian: one that increases substantially the number of members, makes more extensive use of internal sortition and rotation, and recognizes the importance of establishing limited mandates.

We discuss the philosophical implications of formal results showing the con- sequences of adding the epsilon operator to intuitionistic predicate logic. These results are related to Diaconescu’s theorem, a result originating in topos theory that, translated to constructive set theory, says that the axiom of choice (an “existence principle”) implies the law of excluded middle (which purports to be a logical principle). As a logical choice principle, epsilon allows us to translate that result to a logical setting, where one can (...) get an analogue of Diaconescu’s result, but also can disentangle the roles of certain other assumptions that are hidden in mathematical presentations. It is our view that these results have not received the attention they deserve: logicians are unlikely to read a discussion because the results considered are “already well known,” while the results are simultaneously unknown to philosophers who do not specialize in what most philosophers will regard as esoteric logics. This is a problem, since these results have important implications for and promise signif i cant illumination of contem- porary debates in metaphysics. The point of this paper is to make the nature of the results clear in a way accessible to philosophers who do not specialize in logic, and in a way that makes clear their implications for contemporary philo- sophical discussions. To make the latter point, we will focus on Dummettian discussions of realism and anti-realism. Keywords: epsilon, axiom of choice, metaphysics, intuitionistic logic, Dummett, realism, antirealism.

This paper is a beginning—an initial attempt to think of the function and character of epistemic norms as a kind of social norm. We draw on social scientific thinking about social norms and the social games to which they respond. Assume that people individually follow epistemic norms for the sake of acquiring a stock of true beliefs. When they live in groups and share information with each other, they will in turn produce a shared store of true beliefs, an epistemic (...) public good. True beliefs, produced individually or in groups, constitute an epistemic good—one commonly stockpiled and distributed within a community. Epistemic norms can then be understood as a kind of socially developed and transmitted normative sensibility having to do with the production of this individual and public good. Epistemic norms should serve to regulate this practice—coordinating the practice of individuals so as to afford the benefits of life in an interdependent epistemic community—and to manage the risks of being epistemically dependent on others within such a community. Here, we provide some attempts to characterize the central aspects of "the epistemic game"—the epistemic choice situation confronted by communities of epistemic agents. (shrink)

The volume includes twenty-five research papers presented as gifts to John L. Bell to celebrate his 60th birthday by colleagues, former students, friends and admirers. Like Bell’s own work, the contributions cross boundaries into several inter-related fields. The contributions are new work by highly respected figures, several of whom are among the key figures in their fields. Some examples: in foundations of maths and logic ; analytical philosophy, philosophy of science, philosophy of mathematics and decision theory and foundations of economics. (...) Most articles are contributions to current philosophical debates, but contributions also include some new mathematical results, important historical surveys, and a translation by Wilfrid Hodges of a key work of arabic logic.

A counterpossible conditional is a counterfactual with an impossible antecedent. Common sense delivers the view that some such conditionals are true, and some are false. In recent publications, Timothy Williamson has defended the view that all are true. In this paper we defend the common sense view against Williamson’s objections.

Early reactions to the publication of Harold Garfinkel's Studies in Ethnomethodology, which have persisted over the passing decades, was that ethnomethodology could not address what sociology deemed to be socially significant matters such as 'power' and 'the state'. This, however, is not the case. How such matters enter into the practical everyday affairs of members is of equal interest to ethnomethodology when compared to how any matter enters into members' everyday life, and how they display that. It just does not (...) have more importance. Egon Bittner spelt this out with regard to Weber's interest in bureaucracy when he reminds sociology that when Weber talked about efficiency he was not referring to an objective standard but as something that is attuned to practical interests as they emerge in the context of everyday life. This paper examines some of the actions and interactions that were encountered in a Governmental Department in one of the European countries. It makes visible how characterisations of bureaucracy such as 'rational', and 'efficient' are achieved in the actions and interactions of Department employees, and some of the practices involved in that achievement. Garfinkel, and ethnomethodology in general, are not, in principle, to be found wanting where matters of overarching, primordial interest to sociology are concerned. (shrink)

This chapter examines how epistemic norms could be social norms, with a reliance on work on the philosophy and social science of social norms from Bicchieri (on the one hand) and Brennan, Eriksson, Goodin and Southwood (on the other hand). We explain how the social ontology of social norms can help explain the rationality of epistemic cooperation, and how one might begin to model epistemic games.

In "Epistemic Norms and the 'Epistemic Game' They Regulate", we advance a general case for the idea that epistemic norms regulating the production of beliefs might usefully be understood as social norms. There, we drew on the influential account of social norms developed by Cristina Bicchieri, and we managed to give a crude recognizable picture of important elements of what are recognizable as central epistemic norms. Here, we consider much needed elaboration, suggesting models that help one think about epistemic communities (...) and, ultimately, the temptations confronted in one's epistemic life. We suggest that once "the epistemic game" is embedded into a wider set of gains and losses, one can understand the epistemic choice situation as a form of mixed-motive game. This allows one to understand epistemic games more straightforwardly using Bicchieri's framework for thinking about social norms. That is, once the choice situation denominated only in terms of classical epistemic gains and losses is embedded in a wider accounting of goods that may compete with the production of true beliefs, one can see how an agent's individual and community epistemic project can be furthered by social norms regulating epistemic practices. We recommend thinking of epistemic norms as analogous to social norms for hygiene. (shrink)

Promyelocytic leukaemia nuclear bodies (PML NBs) are generally present in all mammalian cells, and their integrity correlates with normal differentiation of promyelocytes. Mice that lack PML NBs have impaired immune function, exhibit chromosome instability and are sensitive to carcinogens. Although their direct role in nuclear activity is unclear, PML NBs are implicated in the regulation of transcription, apoptosis, tumour suppression and the anti‐viral response. An emerging view is that they represent sites where multi‐subunit complexes form and where post‐translational modification of (...) regulatory factors, such as p53, occurs in response to cellular stress. Following DNA damage, several repair factors transit through PML NBs in a temporally regulated manner implicating these bodies in DNA repair. We propose that PML NBs are dynamic sensors of cellular stress, which rapidly disassemble following DNA damage into large supramolecular complexes, dispersing associated repair factors to sites of damage. The dramatically increased total surface area available would enhance interactions between PML‐associated factors regulating DNA repair and apoptosis.

From recent writings of Brent Mundy and Michael Friedman we reconstruct two different representation-theoretic or embedding accounts of space-time relationalism, involving two different conditions on embeddings: respectively, uniqueness up to symmetry and uniqueness up to indistinguishability. We discuss the properties of these two accounts, and, with respect specifically to Friedman's projects, assess their merits and demerits.

We criticise Shepard's notions of “invariance” and “universality,” and the incorporation of Shepard's work on inference into the general framework of his paper. We then criticise Tenenbaum and Griffiths' account of Shepard (1987b), including the attributed likelihood function, and the assumption of “weak sampling.” Finally, we endorse Barlow's suggestion that minimum message length (MML) theory has useful things to say about the Bayesian inference problems discussed by Shepard and Tenenbaum and Griffiths.
