ABSTRACT. May scientists rely on substantive, a priori presuppositions? Quinean naturalists say "no," but Michael Friedman and others claim that such a view cannot be squared with the actual history of science. To make his case, Friedman offers Newton's universal law of gravitation and Einstein's theory of relativity as examples of admired theories that both employ presuppositions (usually of a mathematical nature), presuppositions that do not face empirical evidence directly. In fact, Friedman claims that the use of such presuppositions is (...) a hallmark of "science as we know it." But what should we say about the special sciences, which typically do not rely on the abstruse formalisms one finds in the exact sciences? I identify a type of a priori presupposition that plays an especially striking role in the development of empirical psychology. These are ontological presuppositions about the type of object a given science purports to study. I show how such presuppositions can be both a priori and rational by investigating their role in an early flap over psychology's contested status as a natural science. The flap focused on one of the field's earliest textbooks, William James's Principles of Psychology. The work was attacked precisely for its reliance on a priori presuppositions about what James had called the "mental state," psychology's (alleged) proper object. I argue that the specific presuppositions James packed into his definition of the "mental state" were not directly responsible to empirical evidence, and so in that sense were a priori; but the presuppositions were rational in that they were crafted to help overcome philosophical objections (championed by neo-Hegelians) to the very idea that there can be a genuine science of mind. Thus, my case study gives an example of substantive, a priori presuppositions being put to use—to rational use—in the special sciences. In addition to evaluating James's use of presuppositions, my paper also offers historical reflections on two different strands of pragmatist philosophy of science. One strand, tracing back through Quine to C. S. Peirce, is more naturalistic, eschewing the use of a priori elements in science. The other strand, tracing back through Kuhn and C. I. Lewis to James, is more friendly to such presuppositions, and to that extent bears affinity with the positivist tradition Friedman occupies. (shrink)

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truth which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

A compact, coherent introduction to the study of rational belief, this text provides points of entry to such areas of philosophy as theory of knowledge, methodology of science, and philosophy of language. The book is accessible to all undergraduates and presupposes no philosophical training.

Putnam's goal is to embed philosophy in social life. The first part of this book is dedicated to metaphysical questions.

1. Naturalism Naturalism, it has been said, is the distinctive development in philosophy over the last thirty years. There has been a naturalistic turn away from the a priori methods of traditional philosophy to a conception of philosophy as continuous with natural science. The doctrine has been extensively discussed and has won considerable following in the USA. This is, on the whole, not true of Britain and continental Europe, where the pragmatist tradition never took root, and the temptations of scientism (...) in philosophy were less alluring. Contemporary American naturalism originates in the writings of Quine, the metaphysician of twentieth-century science. With extraordinary panache, he painted a largescale picture of human nature, of language and of the web of belief. I believe that in almost every major respect, it is, like the picture painted by Descartes, the great metaphysician of seventeenth-century science, mistaken. But it evidently appeals to the spirit of the times. So it is worthy of critical examination and careful refutation. I shall argue that the naturalistic turn is a cul-de-sac – a turn that is to be passed by if we are to keep to the highroad of good sense. Naturalism, like so many of Quine’s doctrines, was propounded in response to Carnap. As Quine understood matters, Carnap had been persuaded by Russell’s Our Knowledge of the External World that it is the task of philosophy to demonstrate that our knowledge of the external world is a logical construction out of, and hence can be reduced to, elementary experiences. Quine rejected the reductionism of Carnap’s Logischer Aufbau, and found the idealist basis uncongenial to his own dogmatic realist behaviourism, inspired by Watson and later reinforced by Skinner. The rejection of reductionism and ‘unregenerate realism’, Quine averred, were the sources of his naturalism (FME 72). What exactly was this? We can distinguish in Quine between three different but inter-related programmes for future philosophy: epistemological, ontological and philosophical naturalism. Naturalized epistemology is to displace traditional epistemology, transforming the investigation into ‘an enterprise within natural science’ (NNK 68) – a psychological enterprise of investigating how the ‘input’ of radiation, etc., impinging on the nerve endings of human beings can ‘ultimately’ result in an ‘output’ of our theoretical descriptions of the external world..

Beginning with a historical overview of relativism, from Pythagoras in ancient Greece to Derrida and postmodernism, Maria Baghramian explores the resurgence of relativism throughout the history of philosophy. She then turns to the arguments for and against the many subdivisions of relativism, including Kuhn and Feyerabend's ideas of relativism in science, Rorty's relativism about truth, and the conceptual relativism of Quine and Putnam. Baghramian questions whether moral relativism leads to moral indifference or even nihilism, and whether feminist epistemology's concerns about (...) the very notion of objectivity can be considered a form of relativism. She concludes the relativism debate by assessing the recent criticisms such as Quine's argument from translation and Davidson's claim that even the motivations behind relativism are unintelligible. Finding these criticisms lacking, Baghramian proposes a moderate form of pluralism which addresses the legitimate worries that give rise to relativism without incurring charges of nihilism or anarchy.

Witchcraft, Oracles, and Magic among the Azande, first published in 1977, was based on anthropological reseaches carried out in the Southern Sudan during the late 1920s. For a decade of so, the book had little discernable impact; but from the early 1950s to present day its influence has grown incalculably, so that it is now difficult even to discuss beliefs about witchcraft or sorcery without reference to it. This abridgement of E.E. Evans-Pritchard's acknowledged masterpiece is intended to make it more (...) accessible to students and the general reader. (shrink)

This book offers a powerful interpretation of the philosophy of William James. It focuses on the multiple directions in which James's philosophy moves and the inevitable contradictions that arise as a result. The first part of the book explores a range of James's doctrines in which he refuses to privilege any particular perspective: ethics, belief, free will, truth and meaning. The second part of the book turns to those doctrines where James privileges the perspective of mystical experience. Richard Gale then (...) shows how the relativistic tendencies can be reconciled with James's account of mystical experience. An appendix considers the distorted picture of James's philosophy that has been refracted down to us through the interpretations of his work by John Dewey. (shrink)

William James’ celebrated lecture on “The Will to Believe” has kindled spirited controversy since the day it was delivered. In this lively reappraisal of that controversy, Father O’Connell contributes some fresh contentions: that James’ argument should be viewed against his indebtedness to Pascal and Renouvier; that it works primarily to validate our “over-beliefs” ; and most surprising perhaps, that James envisages our “passional nature” as intervening, not after, but before and throughout, our intellectual weighing of the evidence for belief.

In comparing his conception of empiricism with that of other like-minded philosophers at the end of his 'Two Dogmas of Empiricism,' W. V. Quine famously emphasized the broader scope of his pragmatist commitment in these terms:Carnap, Lewis, and others take a pragmatic stand on the question of choosing between language forms, scientific frameworks; but their pragmatism leaves off at the imagined boundary between the analytic and the synthetic. In repudiating such a boundary I espouse a more thorough pragmatism.Such remarks have (...) resulted in Quine's work being associated with the American pragmatist tradition, where he is viewed as either continuing or reviving some of the main themes and issues representative of..

The chapter presents a largely sympathetic account of W. V. O. Quine’s account of mathematics and logic. The themes of naturalism, confirmational holism, and ontological relativity are discussed in detail, along with the indispensability argument for the truth of mathematical theories and the existence of mathematical objects.

Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. Defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. Detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. Debates about relativism permeate the whole spectrum of philosophical sub-disciplines. From ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy (...) has felt the need to respond to this heady and seemingly subversive idea. Discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called “analytic and continental” camps in philosophy. And yet, despite a long history of debate going back to Plato and an increasingly large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. This entry attempts to provide a broad account of the many ways in which “relativism” has been defined, explained, defended and criticized. (shrink)

The Divided Self of William James. RICHARD M. GALE.

This paper examines Quine’s web of belief metaphor and its role in his various responses to conventionalism. Distinguishing between two versions of conventionalism, one based on the under-determination of theory, the other associated with a linguistic account of necessary truth, I show how Quine plays the two versions of conventionalism against each other. Some of Quine’s reservations about conventionalism are traced back to his 1934 lectures on Carnap. Although these lectures appear to endorse Carnap’s conventionalism, in exposing Carnap’s failure to (...) provide an explanatory account of analytic truth, they in fact anticipate Quine’s later critique of conventionalism. I further argue that Quine eventually deconstructs both his own metaphor and the thesis of under-determination it serves to illustrate. This enables him to hold onto under-determination, but at the cost of depleting it of any real epistemic significance. Lastly, I explore the implications of this deconstruction for Quine’s indeterminacy of translation thesis. (shrink)

“Pragmatism” is a term to conjure with in recent history of philosophy—for a little over one hundred years various philosophers have used the term to advocate certain projects, to abjure others, to bind themselves with groups of like-minded philosophers, to distance themselves from other groups, to draw narrative arcs through recent history, to obscure other possible arcs, and so on. No one does quite so much with words as philosophers do. But what have they done with the word “pragmatism”?I have (...) begun with the word because the word’s existence cannot be doubted. Whether there is anything in particular meant by or even referred to by the word is a harder question. If pragmatism exists, it exists as a.. (shrink)
