"Learning to explain phenomena such that one continues to be fascinated by the failure of one's explanations creates a continuing cycle of thinking, that is the crux of intelligence. It isn't that one person knows more than another, then. In as sense, it is important to know less than the next person, or at least to be certain of less, thus enabling more curiosity and less explaining away because one has again encountered a well-known phenomenon. The less you know the more you can find out about, and finding out for oneself is what intelligence is all about."
