It’s astonishing to me to read the sense of beleaguerment among scholars of Heidegger (or related thinkers) when confronted with his anti-Semitism. Just as Europe lived from the violence of slavery and colonialism, Christian Europe lived from anti-Semitism. It helped define nations, boundaries (what is Europe? not a continent, even as it’s called “the continent,” but there is of course the religious boundary), and entire modes of cultural and political life. It’s a part of Europe, not as a marginal feature, but, like slavery and colonialism, part of the infrastructure of its own self-realization and meaning. To say Europe is entangled with racism is uncontroversial. To engage Europe without thinking hard and systematically about entanglement? That requires some serious justification.Physic majors should do a semester on Heisenberg's entanglement. Aeronautical engineers on von Braun's. Opera students. Heck, all music students. Logicians and analytical philosophers, to the front of the queue.
