Book excerpt: The world-historical antagonist of this narrative, however, has remained hitherto undisclosed: the Jews, or more specifically "world Judaism." As Trawny shows, world Judaism emerges for Heidegger as a racialized, destructive, technological threat to the German homeland, indeed to any homeland. Trawny pinpoints recurrent anti-Semitic themes in the Notebooks, including Heidegger's adoption of crude cultural stereotypes, his assigning of racial reasons to philsophical decisions (even undermining his Jewish teacher, Edmund Husserl), his especially damning endorsement of a Jewish "world conspiracy" (such as that proposed by the Protocols of the Elders of Zion), and his first published remarks on the extermination camps and gas chambers under the troubling aegis of a Jewish "self-annihilation." Trawny concludes with a thoughtful meditation on how Heidegger's achievements might still be valued despite these horrifying facets of his thought.
