Man needs knowledge in order to survive, and only reason can achieve it; men who reject the responsibility of thought and reason, can exist only as parasites on the thinking of others.
Ayn RandHe wanted nothing, for the time being, except to understand ....

There was no order in his reading; but there was order in what remained of it in his mind.
