This thoroughly revised commentary uses the most recent insights in Heidegger studies to lead the reader through the sometimes difficult text of Being and Time. The clearly marked section-by-section analysis explains the structure of Being and Time, illuminates obscure passages, and presents examples of human experience to elucidate Heidegger's points. So that the reader does not lose sight of the main argument, Gelven summarizes the relevant concepts of Heidegger's chapters prior to his explicit interpretation of each section. Even though Gelven's commentary is primarily intended to be used as a supplement to Being and Time, the text also serves as an articulate study in Heideggerian philosophy.
