" An idle brain is the Devil’s workshop, they say. It is an absurdly incongruous statement. If the Devil is at work in a brain it certainly is not idle. And when one considers how brilliant a personage the Devil is, and what very fine work he turns out, it becomes an open question whether he would have the slightest use for most of the idle brains that cumber the earth. "
