This book will be received ill-naturedly by those who think that a book with such a title ought, mainly anyway, to consist of critical exegesis of the work of its philosophical heroes and/or villains on the “central themes” which Professor Bennett selects for his attention. Such readers are likely to feel that when Bennett attributes this or that view, error, or insight to one of the protagonists, he ought usually t o put the man's name in quotation marks. But such a reaction to this book would be at least churlish, for Bennett explicitly eschews both historical concerns and scholarship except in the limited sense that he sometimes pays close attention to textual details.
