Keith Simmons – författare

The aim of the series is to bring together important recent writing in major areas of philosophical inquiry, selected from a variety of sources, mostly periodicals, which may not be conveniently available to the university student or the general reader. The editors of each volume contribute an introductory essay on the items chosen and on the questions with which they deal. A selective bibliography is appended as a guide to further reading. This volume is designed to set out some of the central issues in the theory of truth. It begins with writings by F. H. Bradley, William James, Gottlob Frege, and Bertrand Russell, and continues wih the classical discussions from the middle of the century (including Wittgenstein, Quine, and Austin), ending with a selection of contemporary contributions, including essays from Donald Davidson and Richard Rorty. The collection draws together, for the first time, the debates between philosophers who favour 'robust' or 'substantive' theories of truth, and those other, 'deflationist' or minimalists, who deny that such theories can be given. The editors provide a substantial introduction, in which they map out this terrain and locate writers from Frege to Wittgenstein and Davidson within it. They also describe how these debates relate to more technical issues, such as work on the Liar paradox and formal truth theories.

This book aims to provide a solution to the semantic paradoxes. It argues for a unified solution to the paradoxes generated by our concepts of denotation, predicate extension, and truth. The solution makes two main claims. The first is that our semantic expressions 'denotes', 'extension' and 'true' are context-sensitive. The second, inspired by a brief, tantalizing remark of Gödel's, is that these expressions are significant everywhere except for certain singularities, in analogy with division by zero. A formal theory of singularities is presented and applied to a wide variety of versions of the definability paradoxes, Russell's paradox, and the Liar paradox. Keith Simmons argues that the singularity theory satisfies the following desiderata: it recognizes that the proper setting of the semantic paradoxes is natural language, not regimented formal languages; it minimizes any revision to our semantic concepts; it respects as far as possible Tarski's intuition that natural languages are universal; it responds adequately to the threat of revenge paradoxes; and it preserves classical logic and semantics. Simmons draws out the consequences of the singularity theory for deflationary views of our semantic concepts, and concludes that if we accept the singularity theory, we must reject deflationism.

This book is about one of the most baffling of all paradoxes - the famous Liar paradox. Suppose we say: 'We are lying now'. Then if we are lying, we are telling the truth; and if we are telling the truth we are lying. This paradox is more than an intriguing puzzle, since it involves the concept of truth. Thus any coherent theory of truth must deal with the Liar. Keith Simmons discusses the solutions proposed by medieval philosophers and offers his own solutions and in the process assesses other attempts to solve the paradox. Unlike such attempts, Simmons' 'singularity' solution does not abandon classical semantics and does not appeal to the kind of hierarchical view found in Barwise's and Etchemendy's The Liar. Moreover, Simmons' solution resolves the vexing problem of semantic universality - the problem of whether there are semantic concepts beyond the expressive reach of a natural language such as English.
