Logical Positivism in Perspective

1986 is the fiftieth anniversary of the publication of A. J. Ayer's Language, Truth and Logic, which is commonly considered one of the most influential books in twentieth-century philosophy. These essays offer a comprehensive appraisal of the influence and impact of Ayer's work and analyze the ways in which Ayer's arguments have been absorbed, modified, or rejected by various philosophers. A noteworthy feature of the book is an original essay by A. J. Ayer that assesses the influence of his work in philosophy over the last fifty years.
