We cannot fight against collectivism, unless we fight against its moral base: altruism. We cannot fight against altruism, unless we fight against its epistemological base: irrationalism. We cannot fight against anything, unless we fight for something--and what we must fight for is the supremacy of reason and a view of man as a rational being.
Ayn RandIn 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 – i.e. he must know his own nature (including his means of knowledge) and the nature of the universe in which he acts – 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.
