Abstract
For Hartnack, British philosophers of ordinary language have changed our conception of philosophy. This movement has one significant contemporary rival, however, in logical positivism, which has had little impact in Britian. He proceeds to discuss four "typical" philosophical problems, the external world, knowledge, the mind, and ethics. The decreasing length of the last two discussions corresponds to their decreasing value. This book is intended primarily for tyros in philosophy; it is not bad for that purpose, though the style is occasionally simplistic, and the proof-reading sub-standard.--W. L. M.
