Alfred Tarski’s work on truth has played such a central role in the discourse on truth that most coming to it for the first time have probably already heard a great deal about what is said there. Unfortunately, since the work is largely technical and Tarski was only tan- gentially philosophical, a certain incautious assimilation dominates many philosophical discussions of Tarski’s ideas, and so, examining Tarski on the concept of truth is in many ways an act of unlearning. -/- In (...) this paper I focus on those key ideas in Tarski’s work that have made a lasting impact on the philosophical discourse. These are the notions of T-sentence, Convention T, Tarskian truth definition, and Tarski’s general limiting theses on the expressibility and definability of truth. Though these ideas are in name familiar, we will seek in this essay to uncover and remove certain widespread misunderstandings of each. Tarski’s name also features prominently in discussions of the liar paradox, so we will take time out to explain Tarski’s connection to this ancient puzzle. (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 Eleven of the essays are previously unpublished or substantially revised.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)
