Analytical Philosophy is a collection of papers on epistemological and logical problems which are currently under review. The editor has attempted to represent several different strands of contemporary analytical philosophy, and has drawn upon sources in England, in the United States and Canada, and in Australia. None of the papers in this volume has previously been published. The Symposia led by Professors Vendler and Gasking, and the paper by Professor Cartwright were delivered at a colloquium held within the Department of Philosophy at Oberlin College, Ohio, in April, 1961.
