a junk heap

Though I wouldn't agree with all of Ayn Rand's conclusions, I definitely agreed with this thought:

"A philosophic system is an integrated view of existence. As a human eing, 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... or let your subconscious accumulate a junk heap of unwarranted conclusions..."
