Michael Moran is fascinated by the thinkers he discusses. But unlike most of them, he has no illusion that philosophy can do the work of science and be even a minor source of factual knowledge. Moreover, being highly speculative, it is unlikely that most philosophy will reveal more to us about the `nature of reality' than, say, imaginative literature. Among other things, the author considers both where the usefulness, and indeed the dangers, of philosophy may lie and how, as an academic subject, it might be practised. `I have written this volume not primarily for fellow academics but for anyone who is really interested in modern philosophy and who would like to know what another thoughtful reader has made of it. In other words, I still cling to the hope that there must somewhere exist an intelligent readership outside the routines of academia itself, consisting of individuals who are deeply concerned with ideas, are already reasonably informed, but feel the need for more stimulus. This book is primarily meant for them.' (Introduction, p. 9) Sir Isaiah Berlin, commenting on the author's article on Coleridge: `It seems to me to be one of the most perceptive pieces on Coleridge that I have ever read in English.'
