"I just recently finished reading Robert Pirsig's Zen and the Art of Motorcycle Maintenance. There's a point toward the end of the book where Pirsig relates his experiences of a few philosophy graduate seminars at the University of Chicago. At one point, the professor asks him his opinion on, I believe, a Socratic dialogue. Pirsig is unable to respond, not because he's dumb, but because, after the question is asked, he begins to replay in his head possible answers and their logical consequences and contradictions--over and over, until everyone has left the classroom except Pirsig."
