In order to live, man must act; in order to act, he must make choices; in order to make choices, he must define a code of values; in order to define a code of values, he must know what he is and where he is โ i.e. he must know his own nature (including his means of knowledge) and the nature of the universe in which he acts โ i.e. he needs metaphysics, epistemology, ethics, which means: philosophy. He cannot escape from this need; his only alternative is whether the philosophy guiding him is to be chosen by his mind or by chance.
Ayn RandFor they have nothing to fight me with, save the brute force of their numbers. I have my mind.
Ayn RandWhat is morality, she asked. Judgement to distinguish right and wrong, vision to see the truth, and courage to act upon it, dedication to that which is good, integrity to stand by the good at any price.
