Are you in a universe which is ruled by natural laws and, therefore, is stable, firm, absolute - and knowable? Or are you in an incomprehensible chaos, a realm of inexplicable miracles, an unpredictable, unknowable flux, which your mind is impotent to grasp? The nature of your actions - and of your ambition - will be different, according to which set of answers you come to accept.
Ayn RandIt's true that there's no such thing as free will. We can't help what we are or what we do. It's not our fault. Nobody's to blame for anything. It's all in your background ... and your glands. If you're good, that's no achievement of yours - you were lucky in your glands. If you're rotten, nobody should punish you - you were unlucky, that's all.
Ayn RandIf any part of your uncertainty, is a conflict between your heart and your mind - follow your mind.
