I saw this as I was working through a portion of Heidegger’s Introduction to Metaphysics in order to discuss his notion of violence:
Heidegger’s own story is quite different. Its backdrop, which often remains implicit, is very traditional and Aristotelian. Although in the final analysis Heidegger “undid” that tradition, he first took care to master it, and he recommended that Heideggerians do the same. “You would be well advised,” he told his students in 1952, “to put off reading Nietzsche for the time being and first study Aristotle for ten to fifteen years” — the way Heidegger himself did.
Except, well, that he didn’t.
