This is a reprint, with new Introduction, of the Harper Torch edition of 1970. The famous introductory lectures collected in this volume represent the distillation of Hegel's mature views on the three most important activities of spirit, and have the further advantage, shared by his lectures in general, of being more comprehensible than those works of his published during his lifetime. A new Introduction, Select Bibliography, Analytical Table of Contents, and the restoration in the section headings of the outline of Hegel's lectures make this new edition particularly useful and welcome.
