Published in 1903, this book was the first comprehensive treatise on the logical foundations of mathematics written in English. It sets forth, as far as possible without mathematical and logical symbolism, the grounds in favour of the view that mathematics and logic are identical. It proposes simply that what is commonly called mathematics are merely later deductions from logical premises. It provided the thesis for which _Principia Mathematica_ provided the detailed proof, and introduced the work of Frege to a wider (...) audience. In addition to the new introduction by John Slater, this edition contains Russell's introduction to the 1937 edition in which he defends his position against his formalist and intuitionist critics.

How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

Book synopsis: "What is truth?" has long been the philosophical question par excellence. The Nature of Truth collects in one volume the twentieth century's most influential philosophical work on the subject. The coverage strikes a balance between classic works and the leading edge of current philosophical research. The essays center around two questions: Does truth have an underlying nature? And if so, what sort of nature does it have? Thus the book discusses both traditional and deflationary theories of truth, as (...) well as phenomenological, postmodern, and pluralist approaches to the problem. The essays are organized by theory. Each of the seven sections opens with a detailed introduction that not only discusses the essays in that section but relates them to other relevant essays in the book. Eleven of the essays are previously unpublished or substantially revised. (shrink)

This book argues that correspondence theories of truth fail because the relation that holds between a true thought and a fact is that of identity, not correspondence. Facts are not complexes of worldly entities which make thoughts true they are merely true thoughts. According to Julian Dodd, the resulting modest identity theory, while not defining truth, correctly diagnoses the failure of correspondence theories, and thereby prepares the ground for a defensible deflation of the concept of truth.

Much as we would like to conceive empirical thought as rationally grounded in experience, pitfalls await anyone who tries to articulate this position, and ...

This chapter replies to arguments, advanced by Gonzalo Rodriguez–Pereyra, for thinking that the intuitions that have inspired theories of truthmaking cannot be accommodated without commitment to truth-making entities. It contains a suggestion about why, even if there are no entities that make propositions true, we should nonetheless be apt to think of truth as grounded. The advocates of truthmakers engage sometimes in a specifically ontological enquiry of a wide-ranging sort, sometimes in the project of understanding truth. Inasmuch as Rodriguez–Pereyra's manner (...) of defending a truthmaker principle makes connections with both of these projects, the objections to his account made in the chapter rebound on them both.

0. My aims in this paper are largely expository: I am more interested in presenting the picture theory than deciding its truth. Even so, I hope that the arguments by which I develop the theory will do something to support it, since I believe that what I will present as Wittgenstein's view is indeed the truth. This is not an admission of insanity, though some things that have been thought intrinsic to the picture theory are things it would be insane (...) to believe. So clearly the view I will present, when compared to the most embracing interpretations, is a partial and selective one. It would be another kind of madness, one I am just as eagre to disown, to suppose that my own favoured selection is the only possible one. That is pretty well the last remark in this paper about other commentators. I trust my reticence entitles me to be presumed catholic until proven nonconformist. (shrink)

I want to promote what I shall call ‘the identity theory of truth’. I suggest that other accounts put forward as theories of truth are genuine rivals to it, but are unacceptable. A certain conception of thinkables belongs with the identity theory’s conception of truth. I introduce these conceptions in Part I, by reference to John McDowell’s Mind and World; and I show why they have a place in an identity theory, which I introduce by reference to Frege. In Part (...) II, I elaborate on the conception of thinkables, with a view to demonstrating that the identity theory’s conception of truth is defensible. Part III is concerned with the theory’s relation to some recent work on the concept of truth: I hope to show that the identity theorist not only has a defensible conception of truth, but also, in the present state of play, has appropriate ambitions.
