Was Heidegger Semitic? To what extent identified with National Socialism? They recover these questions today in the context of the recent publication of Martin Heidegger black notebooks containing his personal notes and philosophical writings between 1930 and 1970. Peter Trawny, the editor of these unpublished notebooks until 2014, provides for the first time an analysis Heidegger's philosophical project in light of these new sources.

The first books, written during the war years, provide textual evidence that Heidegger's anti-Semitism is part of his philosophical and political thought. Trawny emphasizes in them the recurrence of anti-Semitic expressions and belief in the existence of a conspiracy by a "world Jewry", which threatens to destroy the identity of other nations and cultures.

Trawny traces the development of a "grand narrative" of "history of being" in the works of Heidegger with Greek and Germanic culture as protagonists, and the "world Jewry" as an antagonist. In this sense, the "anti-Semitic" predicate applied to Heidegger is especially committed, because in most cases it is used in a way that implies an ideological complicity in the Holocaust. Trawny intends to evaluate Heiddegger thinking regarding anti-Semitism, but trying to separate him from the stigma that has fallen after the Holocaust.

According Trawny, black Notebooks are the philosophical legacy of Martin Heidegger and publication radically change the way that readers will come to your mind.
