This long-awaited volume of The Collected Writings of John Sallis presents his lectures on Martin Heidegger's monumental Being and Time.

The lectures were presented during the 1985–86 academic year at Loyola University of Chicago and during the fall semester of 1999 at Pennsylvania State University. The fourteen years separating the beginning of the two courses is significant in that numerous additional volumes appeared in the Gesamtausgabe and influenced Sallis's interpretation of Being and Time.

This book is a synthesis of the manuscripts of the two separate lecture courses. This volume makes Being and Time accessible to students, while the most advanced scholars will also profit from it.
