There was left the mysterious Second Foundation, the goal of all searches. The Mule must find it to make his conquest of the Galaxy complete. - Isaac Asimov

He was thirty-two. Not old — but he felt old. His body, whatever its mutant mental powers, was physically weak. Every star! Every star he could see — and every star he couldn't see. It must all be his! Revenge on all. On a humanity of which he wasn't a part. On a Galaxy in which he didn't fit.

I believe that scientific knowledge has fractal properties, that no matter how much we learn, whatever is left, however small it may seem, is just as infinitely complex as the whole was to start with. That, I think, is the secret of the Universe.

Don't be so blinded by your morals you fail to do what's right.
