"Thanks to Professor van Buren, we finally have readable translations of these important early texts in versions that do what a translation is meant to do: provide access to the author's way of thinking … Modestly entitled 'supplements,' these texts are illuminating documents of the formative period of perhaps the twentieth century's most important philosopher." — Review of Metaphysics"In this volume John van Buren continues the groundbreaking work he began with the publication of The Young Heidegger by collecting together hitherto unavailable and precious documents from the pre-history of Being and Time, arguably the most important book in twentieth-century European philosophy. Van Buren proves himself as incisive an editor and translator as he is an interpreter of this important period leading up to the publication of Heidegger's major work, and this collection will quickly become standard reading for any serious study of Being and Time." — John D. Caputo, author of Demythologizing Heidegger
