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.".

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)

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.

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)

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.

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).

That choice principles ‘change the logic’ when added to constructive systems is significant for contemporary metaphysics. However, many are surprised by these results, having learned that the Axiom of Choice (AC) is constructively valid. Indeed, even among specialists there were, until recently, reasons for puzzlement-rival versions of Intuitionistic Type Theory, one where (AC) is valid, another where it implies classical logic. This paper accessibly explains the situation, puts the issues in a broader setting by considering other choice principles, and draws (...) philosophical morals for the understanding of quantification, choice principles, and the prospects for constructivism.

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.

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.

The term ars erotica refers to the styles and techniques of lovemaking with the honorific title of art. But in what sense are these practices artistic and how do they contribute to the aesthetics and ethics of self-cultivation in the art of living? In this book, Richard Shusterman offers a critical, comparative analysis of the erotic theories proposed by the most influential premodern cultural traditions that shaped our contemporary world. Beginning with ancient Greece, whose god of desiring love gave (...) eroticism its name, Shusterman examines the Judaeo-Christian biblical tradition and the classical erotic theories of Chinese, Indian, Islamic, and Japanese cultures, before concluding with medieval and Renaissance Europe. His exploration of their errors and insights shows how we could improve the quality of life and love today. By using the engine of eros to cultivate qualities of sensitivity, grace, skill, and self-mastery, we can reimagine a richer, more positive vision of sex education. (shrink)

Public and professional debates have come to rely heavily on a special type of reasoning: the argument-from-ignorance, in which conclusions depend on the _lack_ of compelling information. "I win my argument," says the skillful advocate, "unless you can prove that I am wrong." This extraordinary gambit has been largely ignored in modern rhetorical and philosophical studies. Yet its broad force can be demonstrated by analogy with the modern legal system, where courts have long manipulated burdens of proof with skill and (...) subtlety. This legal, philosophical, and rhetorical study by Richard H. Gaskins provides the first systematic treatment of arguments-from-ignorance across a wide range of modern discourse—from constitutional law, scientific inquiry, and moral philosophy to organizational behavior, computer operation, and personal interaction. Gaskins reviews the historic shifts in constitutional proof burdens that have shaped public debate on fundamental rights and, by analogy, on the fundamental status of intellectual and cultural authority. He shows how similar shifts have dominated polemical battles between scientific and ethical modes of authority, affecting both academic and popular discussion. Finally, he discovers the philosophical roots of default reasoning strategies in the arguments of Kant and nineteenth-century Kantian schools. Concluding that shifting proof burdens are inescapable in a world of scientific and moral uncertainty, Gaskins emphasizes the common strategic ground shared by dogmatic and skeptical reasoning. Using Hegelian strategies, he describes a more pluralistic temper that can move critical thinking beyond polemics and strengthen our capacities for common discourse. (shrink)

John McDowell's "minimal empiricism" is one of the most influential and widely discussed doctrines in contemporary philosophy. Richard Gaskin subjects it to careful examination and criticism, arguing that it has unacceptable consequences, and in particular that it mistakenly rules out something we all know to be the case: that infants and non-human animals experience a world. Gaskin traces the errors in McDowell's empiricism to their source, and presents his own, still more minimal, version of empiricism, suggesting that a correct (...) philosophy of language requires us to recognize a sense in which the world we experience speaks its own language.

This anthology is a significant contribution to the debate over the relevance of Martin Heidegger's Nazi ties to the interpretation and evaluation of his philosophical work. Included are a selection of basic documents by Heidegger, essays and letters by Heidegger's colleagues that offer contemporary context and testimony, and interpretive evaluations by Heidegger's heirs and critics in France and Germany.In his new introduction, "Note on a Missing Text," Richard Wolin uses the absence from this edition of an interview with Jacques (...) Derrida as a springboard for examining questions about the nature of authorship and personal responsibility that are at the heart of the book.Richard Wolin is Professor of Modern European Intellectual History and Humanities at Rice University.

McCarthy thinks truth more important than I do. Specifically, he thinks that “ ‘truth’ … functions as an ‘idea of reason’ with respect to which we can criticize not only particular claims within our language but the very standards of truth we have inherited” . By contrast, I think that what enables us to make such criticism is concrete alternative suggestions—suggestions about how to redescribe what we are talking about. Some examples are Galileo’s suggestions about how to redescribe the Aristotelian (...) universe, Marx’s suggestions about how to redescribe the nineteenth century, Heidegger’s suggestions about how to redescribe the West as a whole, Dickens’s suggestions about how to redescribe chancery law, Rabelais’s suggestions about how to redescriibe monasteries, and Virginia Woolf’s suggestions about how to redescribe women writing.Such fresh descriptions, such new suggestions of things to say, sentences to consider, vocabularies to employ, are what do the work. All that the idea of truth does is to say, “Bethink yourself that you might be mistaken; remember that your beliefs may be justified by your other belies in the area, but that the whole kit and caboodle might be misguided, and in particular that you might be using the wrong words for your purpose.” But this admonition is empty and powerless without some concrete suggestion of an alternative set of beliefs, or of words. Moreover, if you have such a suggestion, you do not need the admonition. The only cash value of this regulative idea is to commend fallibilism, to remind us that lots of people have been as certain of, and as justified in believing, things that turned out to be false as we are certain of, and justified in holding, our present views. It is not, as McCarthy says, a “moment of unconditionality that opens us up to criticism from other points of view” . It is the particular attractions of those other points of view.Richard Rorty is University Professor of Humanities at the University of Virginia.

Isaac Newton was indisputably one of the greatest scientists in history. His achievements in mathematics and physics marked the culmination of the movement that brought modern science into being. Richard Westfall's biography captures in engaging detail both his private life and scientific career, presenting a complex picture of Newton the man, and as scientist, philosopher, theologian, alchemist, public figure, President of the Royal Society, and Warden of the Royal Mint. An abridged version of his magisterial study Never at Rest, (...) this concise biography makes Westfall's highly acclaimed portrait of Newton newly accessible to general readers. (shrink)

Since economies are dynamic processes driven by creativity, social norms, and emotions as well as rational calculation, why do economists largely study them using static equilibrium models and narrow rationalistic assumptions? Economic activity is as much a function of imagination and social sentiments as of the rational optimisation of given preferences and goods. Richard Bronk argues that economists can best model and explain these creative and social aspects of markets by using new structuring assumptions and metaphors derived from the (...) poetry and philosophy of the Romantics. By bridging the divide between literature and science, and between Romanticism and narrow forms of Rationalism, economists can access grounding assumptions, models, and research methods suitable for comprehending the creativity and social dimensions of economic activity. This is a guide to how economists and other social scientists can broaden their analytical repertoire to encompass the vital role of sentiments, language, and imagination. (shrink)

Buddhist intellectual discourse owes its development to a dynamic interplay between primary source materials and subsequent interpretation, yet scholarship on Indian Buddhism has long neglected to privilege one crucial series of texts. Commentaries on Buddhist scriptures, particularly the sutras, offer rich insights into the complex relationship between Buddhist intellectual practices and the norms that inform—and are informed by—them. Evaluating these commentaries in detail for the first time, Richard F. Nance revisits—and rewrites&mdashthe critical history of Buddhist thought, including its unique (...) conception of doctrinal transmission. Attributed to such luminaries as Nagarjuna, Vasubandhu, Dignaga, and Santideva, scriptural commentaries have long played an important role in the monastic and philosophical life of Indian Buddhism. Nance reads these texts against the social and cultural conditions of their making, establishing a solid historical basis for the interpretation of key beliefs and doctrines. He also underscores areas of contention, in which scholars debate what it means to speak for, and as, a Buddha. Throughout these texts, Buddhist commentators struggle to deduce and characterize the speech of Buddhas and teach others how to convey and interpret its meaning. At the same time, they demonstrate the fundamental dilemma of trying to speak on behalf of Buddhas. Nance also investigates the notion of "right speech" as articulated by Buddhist texts and follows ideas about teaching as imagined through the common figure of a Buddhist preacher. He notes the use of epistemological concepts in scriptural interpretation and the protocols guiding the composition of scriptural commentary, and provides translations of three commentarial guides to better clarify the normative assumptions organizing these works.

Some theorists who accept the existence of global justice duties to alleviate the condition of distant needy strangers hold that these duties are significantly constrained by special ties to fellow countrymen. The patriotic priority thesis holds that morality requires the members of each nation-state to give priority to helping needy fellow compatriots over more needy distant strangers. Three arguments for constraint and patriotic priority are examined in this essay: an argument from fair play, one from coercion, another from coercion and (...) autonomy. Under scrutiny, none of these arguments qualifies as successful. (shrink)

Abstract: I argue that for psychological and social reasons, the traditional “Conflict Model” of science and religion interactions has such a strong hold on the nonexpert imagination that counterexamples and claims that interactions are simply more complex than the model allows are inadequate to undermine its power. Taxonomies, such as those of Ian Barbour and John Haught, which characterize conflict as only one among several possible relationships, help. But these taxonomies, by themselves, fail to offer an account of why different (...) relationships prevail among different communities and how they succeed one another within particular communities—that is, they contain no dynamic elements. To undermine the power of the “Conflict Model,” we should be seeking to offer alternative models for science and religion interactions that can both incorporate the range of stances articulated by scholars like Barbour and which can offer an account of the process by which differing attitudes succeed one another. As a step toward this goal, I propose a general “interacting subcultures model” and illustrate its applicability in a small number of mini-case studies from Early Modern Britain and France and with glances toward contemporary America.

Samuels and Stich explore the debate over the extent to which ordinary human reasoning and decision making is rational. One prominent cluster of views, often associated with the heuristics and biases tradition in psychology, maintains that human reasoning is, in important respects, normatively problematic or irrational. Samuels and Stich start by sketching some key experimental findings from this tradition and describe a range of pessimistic claims about the rationality of ordinary people that these and related findings are sometimes taken to (...) support. Such pessimistic interpretations of the experimental findings have not gone unchallenged however: Samuels and Stich outline some of the research on reasoning that has been done by evolutionary psychologists and sketch a cluster of more optimistic theses about ordinary reasoning that such psychologists defend. Although Samuels and Stich think that the most dire pronouncements made by writers in the heuristics and biases tradition are unwarranted, they also maintain that the situation is rather more pessimistic than sometimes suggested by evolutionary psychologists. They conclude by defending this “middle way” and sketch a family of “dual processing” theories of reasoning which, they argue, offer some support for the moderate interpretation they advocate.

This essay describes modern American legal pragmatism. Its origins in pragmatist philosophy are traced, and it is compared with the law and economics movement in American law and the formalist style of Continental legal theory. The essay argues that the inevitability of legal pragmatism in America, and its dispensability in Europe, reflect fundamental institutional and cultural differences rather than mere accidents of history or legal thought.

This book explores the epistemology and the methodology of political knowledge and social inquiry. What can we know, and how do we know? Friedrich V. Kratochwil and Ted Hopf question all foundational claims of inquiry and envisage science as a self-reflective practice. Brian Pollins and Fred Chernoff accept their arguments to some degree and explore the implications for logical positivism. David A. Waldner, Jack Levy, and Andrew Lawrence address the purpose and methods of research. They debate the role of explanation (...) versus prediction, the relationship of theory to evidence, and their implications for the Democratic Peace research program. A concluding chapter by Mark Lichbach offers a pluralistic reformulation of neopositivism. An alternative conclusion by Steven Bernstein, Richard Ned Lebow, Janice Gross Stein and Steven Weber contends that social science should be modeled on medicine and reformulated as a set of case-based diagnostic tools. The distinguishing feature of the book is the inclusion of authors who represent different approaches to social science and their willingness to engage with one another in a constructive debate.

One of the greatest dramatists of all time, Shakespeare, recognized that dramatic action was not limited to the stage. Now, in Drama and Intelligence, a work firmly rooted in developmental drama, Richard Courtney is the first to examine dramatic action as an intellectual and cognitive activity. Courtney explores the nature of those experiences we live "through" and which involve us in what is termed "as if" thinking and action.

When wealthy Jewish industrialist David Friedländer proposed in 1799 that Berlin's Jews undergo a sham conversion to Christianity in return for full German citizenship, he touched off a political and theological debate that would continue to define the relation between Jewish and German identity for more than a century. In the series of provocative letters collected here, Friedländer, Protestant leader Wilhelm Abraham Teller, and young Christian theologian Friedrich Schleiermacher debate Friedländer's radical proposal. In so doing, they grapple with many of (...) the thorny problems--such as citizenship, religious tolerance, and assimilation--that continue to vex world political leaders today. Richard Crouter's Introduction provides the cultural, religious, and historical context for this compelling exchange; a postscript by Julie Klassen reveals the ways in which Germany's minorities continue to be marginalized more than two hundred years after Friedländer made his passionate appeal for political liberty and human rights.

"One might say that where Religion becomes artificial, it is reserved for Art to save the spirit of religion." With these words Richard Wagner began "Religion and Art" (1880), one of his most passionate essays. That passion made Wagner himself a central icon in the growing cult of art. Wagner felt that he lived in an age of spiritual crisis. "It can but rouse our apprehension, to see the progress of the art-of-war departing from the springs of moral force, (...) and turning more and more to the mechanical," he wrote. In response to the frightening progress of dynamite and steel, Wagner adopted the role of the Tone Poet Seer, who reveals the inexpressible in concert halls and cleanses souls in waves of symhonic revelation. "Religion and Art" is the pivot of the works collected here. Also included are his defining essays "Public and Popularity" and "The Public in Time and Space"; his papers relating to the creation of the Bayreuth School; his complaint against publishers, "On Poetry and Composition" (1879); his article on the first production of Parsifal (1882); and other works that speak his mind about strengthening the spirit through music. These works participated in the duel between Wagner and Nietzsche that ensued after the breakup of their friendship in 1878. Nietzsche publicly called Wagner an incurable romantic, emphasizing how sick he thought both Wagner and his art were. Here Wagner counterattacks with arch innuendo and sarcasm. This edition includes the complete volume 6 of the 1897 translation of Wagner's works commissioned by the London Wagner Society. William Ashton Ellis is one of the most important translators of nineteenth-century musicology. In addition to his monumental translation of Wagner's prose works, he translated Wagner's correspondence with Franz Lizst, Mathilde Wesendonck, and Wagner's own family. Ellis died in 1919. (shrink)

Adorno unquestionably loved opera music as much as he hated opera as a cultural institution. His take on opera in the twentieth century led him to write its socio‐political obituary, while recognizing at the same time that opera continued to attract a steady stream of would‐be onlooker‐auditors. Paradoxically for Adorno, opera continued to appeal to audiences, and – from his dialectical reckoning – characteristically for precisely the wrong reasons. His opera analyses address the sociology of musical theater, performance hermeneutics, and (...) the direct consideration of music itself (though given his typical writing mode this writing is perhaps best characterized as criticism rather than analysis, as the latter term is commonly employed within musicology). Adorno's interests principally revolve around modern opera (Schoenberg, Berg, Strauss, Weill, especially) but also, if to a lesser extent, canonic works from Mozart to Verdi. Wagner, Wagnerian music drama, and cultural Wagnerism more generally were special cases for Adorno, and subjects he returned to repeatedly throughout his adult life, coinciding with the rise and fall of National Socialism and the Wagner cult, which in the 1930s and 1940s war years comfortably accommodated fascist proclivities. Adorno recognized the socio‐cultural agency of opera as a still‐prestigious cultural leftover of nineteenth‐century bourgeois triumphalism, which he vigorously opposed. In its place, he labored to promote what he regarded as a more socially responsible musico‐operatic practice to supplant the aesthetic and social complacency of the established order, ideas that after his death have found considerable currency, nowhere more evident than in late‐modern opera productions throughout the world.

The result is a rewarding and refreshing book that clarifies longstanding controversies and stakes out novel positions in the debates.

I argue that while much of what he states is correct, he errs in holding that induction is invalid in the short run of an individual’s (...) life. (shrink)
