"The translators have improved upon their excellent, earlier translation: nuances have been made clearer and the style brought closer to Heidegger's own style.  Eminently readable, this translation should stand the test of time."—Dennis J. Schmidt, Pennsylvania State University"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"The quality of the translation is outstanding, and the introduction and glossary are eminently clear and helpful."—Bret W. Davis, author of Heidegger and the Will: On the Way to Gelassenheit"There is no questioning the exceedingly high quality of Polt and Fried’s translation as well as their reliably judicious choice of words. Students and scholars alike profit immensely, too, from the explanations that they give of specific translations."—Daniel Dahlstrom, Boston University"Fried and Polt have produced a first-rate edition of this pivotal and important text. Their new translation is rigorous and abides by the best standards of Heidegger scholarship. It also has a new fluency that brings this difficult text into reach of English language readers."—Dennis J. Schmidt, Penn State University
