Happiness is not to be achieved at the command of emotional whims.

These are the things before me. And as I stand here at the door of glory, I look behind me for the last time. I look upon the history of men, which I have learned from the books, and I wonder. It was a long story, and the spirit which moved it was the spirit of man’s freedom. But what is freedom? Freedom from what? There is nothing to take a man’s freedom away from him, save other men.

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 – 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.
