Deflationsism about truth is a pot-pourri, variously claiming that truth is redundant, or is constituted by the totality of 'T-sentences', or is a purely logical device (required solely for disquotational purposes or for re-expressing finitarily infinite conjunctions and/or disjunctions). In 1980, Hartry Field proposed what might be called a 'deflationary theory of mathematics', in which it is alleged that all uses of mathematics within science are dispensable. Field's criterion for the dispensability of mathematics turns on a property of theories, called (...) conservativeness. I present some technical results, some of which may be found in Tarski (1936), concerning the logical properties of truth theories; in particular, concerning the conservativeness of adding a truth theory for an object level language to any theory expressed in it. It transpires that various deflationary truth theories behave somewhat differently from the standard Tarskian truth theory. These results suggest that Tarskian theories of truth are not redundant or dispensable. Finally, I hint at an analogy between the behaviour of mathematical theories and of standard (Tarskian) theories of truth with respect to their indispensability to, as Quine would put, our 'scientific world-view'.

What is truth. Paul Horwich advocates the controversial theory of minimalism, that is that the nature of truth is entirely captured in the trivial fact that each proposition specifies its own condition for being true, and that truth is therefore an entirely mundane and unpuzzling concept. The first edition of Truth, published in 1980, established itself as the best account of minimalism and as an excellent introduction to the debate for students. For this new edition, Horwich has refined and developed (...) his treatment of the subject in the light of subsequent discussions, while preserving the distinctive format that made the earlier edition so successful.

I define T-schema deflationism as the thesis that a theory of truth for our language can simply take the form of certain instances of Tarski's schema (T). I show that any effective enumeration of these instances will yield as a dividend an effective enumeration of all truths of our language. But that contradicts Gödel's First Incompleteness Theorem. So the instances of (T) constituting the T-Schema deflationist's theory of truth are not effectively enumerable, which casts doubt on the idea that the (...) T-schema deflationist in any sense has a theory of truth. (The argument in section 2 of "Semantics for Deflationists" supercedes this paper.). (shrink)

Schmitt allots a chapter to each of the main types of theories about truth: pragmatism, coherentism, deflationism, and the correspondence theory. He discusses various arguments for these positions and concludes that only the arguments supporting the correspondence theory are successful. Schmitt's positive case for correspondence makes up the least original part of the book. He explicitly credits Field and remarks that he is mainly concerned with making Field's difficult account more accessible —a task that he discharges honorably..) Schmitt also offers (...) detailed discussions of about fifteen negative arguments aimed against pragmatism, coherentism, and deflationism. He finds most of them effective, with the result that the correspondence theory emerges as the only tenable account of truth. He discusses some objections but seems somewhat less eager to raise problems for his own view than for its competitors. (shrink)

The concept of truth lies at the heart of philosophy; whether one approaches it from epistemology or metaphysics, from the philosophy of language or the philosophy of science or religion, one must come to terms with the nature of truth.In this brisk introduction, Frederick Schmitt covers all the most important historical and contemporary theories of truth. Along the way he also sheds considerable light on such closely related issues as realism and idealism, absolutism and relativism, and the nature of contemporary (...) pragmatism.At a time when it is fashionable for scholars outside of philosophy to deny the possibility of truth, Schmitt’s lucid, technically accurate survey offers the easiest way to understand what is really at stake in such denials. Truth: A Primer is a quick but accurate and philosophically sophisticated overview that will prove invaluable to philosophers and their students in a wide range of courses, in particular epistemology, metaphysics, and philosophy of language.
