Ayn RandLive and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.

Ayn RandThe good, say the mystics of spirit, is God, a being whose only definition is that he is beyond man's power to conceive — a definition that invalidates man's consciousness and nullifies his concepts of existence. The good, say the mystics of muscle, is Society — a thing which they define as an organism that possesses no physical form, a super-being embodied in no one in particular and everyone in general except yourself.... The purpose of man's life, say both, is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question.
