A.C. Grayling is one of Britain's leading thinkers, highly regarded as a public philosopher of distinction as well as in academic circles 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 Encyclopaedia of British Philosophy. 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. This volume of selected essays includes his work in the philosophy of language and philosophical logic, with particular focus on truth, judgment and the realism-anti-realism debate. Each essay is intended as a further contribution to previous topics covered and aims to bring them up-to-date. As such, this collection does not aspire to be the last word on a theory, but rather to advance a perspective and add relevant suggestions to understanding them further.
