A. J. Ayer

I am very much honoured to have been asked to make the closing speech at this Conference. Since this is the first time for over fifty years that a philosophical congress of this scope has been held in England, I hope that you will think it suitable for me to devote my lecture to the revival of the empiricist tradition in British philosophy during this century. I shall begin by examining the contribution of the Cambridge philosopher G. E. Moore. Though (...) he first owed his fame to his book Principia Ethica regarded as a work of genius by the Cambridge Apostles and their associates in Bloomsbury, who did not venture to question Moore's mistaken view of ‘good’ as an unanalysable non-natural quality, his reputation now chiefly rests on his subsequent defence of common sense.

This is a representative collection of the work of A.J. Ayer, one of the most influential contemporary philosophers. It includes his Whidden lectures on freedom and morality, which were presented at McMaster University in 1983, a previously unpublished essay on J.L. Mackie's Theory of Causal Priority, and seven other essays which cover such topics as: references and identity, the causal theory of perception, the prisoner's paradox, self-evidence and certainty, and the history of the Vienna Circle.

This book was originally conceived as a sequel to bertrand russell's "a history of western philosophy". it takes up where russell left off. rather than examining a wide number of philosophers superficially, this book deals with a small number of philosophers in depth. the book examines american pragmatists, the analytic movement, phenomenology and existentialism. it examines both critical and speculative philosophy. (staff).

Eventually, the series will encompass every major academic discipline, offering all readers an accessible and abundant reference library.

A. J. Ayer was one of the foremost analytical philosophers of the twentieth century, and was known as a brilliant and engaging speaker. In essays based on his influential Dewey Lectures, Ayer addresses some of the most critical and controversial questions in epistemology and the philosophy of science, examining the nature of inductive reasoning and grappling with the issues that most concerned him as a philosopher. This edition contains revised and expanded versions of the lectures and two additional essays. Ayer (...) begins by considering Hume's formulation of the problem of induction and then explores the inferences on which we base our beliefs in factual matters. In other essays, he defines the three kinds of probability that inform inductive reasoning and examines the various criteria for verifiability and falsifiability. In his extensive introduction, Graham Macdonald discusses the arguments in _Probability and Evidence_, how they relate to Ayer's other works, and their influence in contemporary philosophy. He also provides a brief biographical sketch of Ayer, and includes a bibliography of works about and in response to _Probability and Evidence_. (shrink)
