This new edition of one of Heidegger?s most important works features a revised and expanded translators? introduction and an updated translation, as well as the first English versions of Heidegger?s draft of a portion of the text and of his later critique of his own lectures. Other new features include an afterword by Petra Jaeger, editor of the German text.   ?This revised edition of the translation of Heidegger?s 1935 lectures, with its inclusion of helpful new materials, superbly augments the excellent translation provided in the first edition. The result is a richly rewarding volume, to be recommended to every student of Heidegger?s works, whether a novice or a long-time reader.??Daniel Dahlstrom, Boston University
