> One of the main issues of contention is the claim that Wittgenstein triggered or substantially contributed to Hitler's antisemitism while they were at school together. It is a view that has some support. British professor Laurence Goldstein, in his Clear and Queer Thinking: Wittgenstein's Development and His Relevance to Modern Thought (1999), called Cornish's book important, writing: "For one thing, at the K.u.k. Realschule in Linz, Wittgenstein met Hitler and may have inspired in him a hatred of Jews which led, ultimately, to the Holocaust. This, naturally enough, weighed heavily on Wittgenstein's conscience in his later years ... It is overwhelmingly probable that Hitler and Wittgenstein did meet, and with dire consequences for the history of the world."[6]
