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 RandIf you want to know the one reason that's taking me back, I'll tell you: I cannot bring myself to abandon to destruction all the greatness of the world, all that which was mine and yours, which was made by us and is still ours by right - because I cannot believe that men refuse to see, that they can remain blind and deaf to us forever, when the truth is ours and their lives depend on accepting it.
