Edited by a A.J. Ayer, Logical Positivism offers--in the words of the movement's founders--revolutionary theories on meaning and metaphysics, the nature of logic and mathematics, the foundations of knowledge, the content of psychological propositions, ethics, sociology, and the nature of philosophy itself.

In the pages of this book, readers will find classic papers by Schlick, Carnap, Neurath, and Hanh published for the first time in English. In the most complete bibliography on the subject, Logical Positivism explains the movement's main ideas and their impact on contemporary philosophy in Britain and the United States.
