A fact about the philosopher Ludwig Wittgenstein #2

For a period of two days when he was lurking around Cambridge in 1929, Ludwig Wittgenstein, author of the Tractatus Logico-Philosophicus, wore nothing but a set of two-toned leather shoes. When asked by a young student to explain his nakedness, Wittgenstein hit him over the head with a copy of Kant's Critique of Practical Reason, which he was studying at the time: "The beauty of a circle is not that it has no beginning but that it has no end!" he screamed. He wasn't seen again for a week and a half.
