I remember once in college, I had a professor say, "Wittgenstein was a really odd guy. He was this super cerebral philosopher and enthusiastically fought in World War I. When he was teaching a class, he used to a lot of the time show up like fifteen minutes late, sit at the head of the class for ten or fifteen minutes just muttering, "I ... I just can't ... I can't, I'm out of my league ..." and then eventually run out of his classroom.
Sometimes I feel like that with this blog.
