A.C. Grayling is one of Britain's leading philosophers, known for his scholarly work on Descartes, Berkeley, Russell and Wittgenstein, his writings on the problem of scepticism, his widely used Introduction to Philosophical Logic and (as editor) his two volume philosophy and (as chief editor) The Continuum Encyclopedia of British Philosophy. In this volume of selected essays, Grayling includes works on the philosophy of language and philosophical logic, focusing on debates about truth, reference, assertion, judgment, and the realism-anti-realism debate. He sees the essays as contributions made to the debates which give these topics their life, not aspiring to be the last word on any of them, but rather to advance a perspective and a set of suggestions relevant to understanding them further. This book serves as an excellent guide to Grayling's main philosophical concerns and shows the intellectual underpinning of much of his more popular work.
