"A philosophic system is an integrated view of existence. As a human being, you have no choice about the fact that you need a philosophy. Your only choice is whether you define your philosophy by a conscious, rational, disciplined process of thought and scrupulously logical deliberation--or let your subconscious accumulate a junk heap of unwarranted conclusions, false generalizations, undefined contradiction, undigested slogans, unidentified wishes, doubts and fears, thrown together by chance, but integrated by your subconscious into a kind of mongrel philosophy and fused into a single, solid weight; self-doubt, like a ball and chain in the place where your mind's wings should have grown." —Ayn Rand
