Division III of Heidegger's Being and Time

Book excerpt: "Heidegger's Being and Time" is one of the most influential and important books in the history of philosophy, but it was left unfinished. The parts we have of it, Divisions I and II of Part One, were meant to be merely preparatory for the unwritten Division III, which was to have formed the point of the entire book when it turned to the topic of being itself. In this book, leading Heidegger scholars and philosophers influenced by Heidegger take up the unanswered questions in Heidegger's masterpiece, speculating on what Division III would have said, and why Heidegger never published it. The contributors' task--to produce a secondary literature on a nonexistent primary work--seems one out of fiction by Borges or Umberto Eco. Why did Heidegger never complete Being and Time? Did he become dissatisfied with it? Did he judge it too subjectivistic, not historical enough, too individualistic, too existential? Was abandoning it part of Heidegger's "Kehre", his supposed turning from his early work to his later work? Might Division III have offered a bridge between the two phases, if a division exists between them? And what does being mean, after all? The contributors, in search of lost Being and Time, consider these and other topics, shedding new light on Heidegger's thought.
