Of Principles
You have no choice about the necessity to integrate your observations, your experiences, your knowledge into abstract ideas, i.e., into principles. Your only choice is whether these principles are true or false, whether they represent your conscious, rational convictions - or a grab-bag of notions snatched at random, whose sources, validity, context and consequences you do not know, notions which, more often that not, you would drop like a hot potato if you knew. Ayn Rand, Philosophy: Who Needs It
