This important new book condenses and rephrases, paragraph by paragraph, the entirety of Heidegger's magnum opus Being and Time. Leading Heidegger scholar Thomas Sheehan renders the text in reader-friendly language that avoids the worst of the Heideggerese that persists in the wider scholarship. He helpfully outlines each of the six chapters and, in turn, each of the eighty-three individual sections of the book, providing a critical and insightful commentary that draws on Heidegger's comments on Being and Time throughout his career. The book also includes commentary and guidance on the terminology, scope, arguments, achievements, and limitations of Being and Time. This reader's guide is an essential resource for students, scholars and anyone engaging with Heidegger's complex work.
