Ergänzungen und Denksplitter

Hidden behind the unassuming title of this volume are pieces from the unpublished estate that further illuminate some of Heidegger's central themes, but in some cases also apt to provide surprises. Three volumes of handwritten notes originate from the phase of the turning of thought at the beginning of the 1930s and are devoted to the concept of force in Aristoteles' "Metaphysics", the copula, and the principle of contradiction, the latter material also including two versions of the Freiburg lecture of December 16, 1932. A fourth volume documents the meeting that followed the lecture "Was ist das - die Philosophie?" given in Cerisy in the summer of 1955, showing Heidegger in conversation with Gabriel Marcel, Paul Ricoeur, Lucien Goldmann, Gilles Deleuze, and others. 141 smaller pieces from the unpublished estate contain thoughts from four decades on truth, language, science, technology, art, poetry, and other topics of event thinking.
