<DIV>Long awaited and eagerly anticipated, this remarkable volume allows English-speaking readers to experience a profound dialogue between the German philosopher Martin Heidegger and the Swiss psychiatrist Medard Boss. A product of their warm friendship, <I>Zollikon Seminars</I> chronicles an extraordinary exchange of ideas. Heidegger strove to transcend the bounds of philosophy while Boss and his colleagues in the scientific community sought to understand their patients and their world. The result: the best and clearest introduction to Heidegger's philosophy available.<BR><BR>Boss approached Heidegger asking for help in reflective thinking on the nature of Heidegger's work. Soon they were holding annual two-week meetings in Boss's home in Zollikon, Switzerland. The protocols from these seminars, recorded by Boss and reviewed, corrected, and supplemented by Heidegger himself, make up one part of this volume. They are augmented by Boss's record of the conversations he had with Heidegger in the days between seminars and by excerpts from the hundreds of letters the philosopher wrote to Boss between 1947 and 1971.<BR></DIV>
