You don't believe that your friend could ever do anything great. You despise yourself in secret, even – no, especially – when you stand on your dignity; and since you despise yourself, you are unable to respect your friend. You can't bring yourself to believe that anyone you have sat at table with, or shared a house with, is capable of great achievement. That is why all great men have been solitary. It is hard to think in your company, little man. One can only think 'about' you, or 'for your benefit', not 'with' you, for you stifle all big, generous ideas.

I am not a Christian or a Jew or a Mohammedan, a Mormon, Polygamist, Homosexual, Anarchist or Boxer. . . . I do not believe that, in order to be religious in the good and genuine sense of the word, one has to ruin one's love life and has to become rigid and shrunken in body and soul. I know that what you call "God" actually exists, but in a different way from what you think: as the primal cosmic energy in the universe, as your love in your body, as your honesty and your feeling of nature in you and around you.

Follow the voice of your heart, even if it leads you off the path of timid souls. Do not become hard and embittered, even if life tortures you at times. There is only one thing that counts: to live one's life well and happily.

Honest pioneer work in the field of science has always been, and will continue to be, life's pilot. On all sides, life is surrounded by hostility. This puts us under an obligation.

Mistaking insolence for freedom has always been the hallmark of the slave.

Because you have no memory for things that happened ten or twenty years ago, you're still mouthing the same nonsense as two thousand years ago. Worse, you cling with might and main to such absurdities as 'race,' 'class,' 'nation,' and the obligation to observe a religion and repress your love.

Because I'm a man who works, who knows what a human being is like inside, who knows that every human being has his worth, and who wants the world to be governed by work and not by opinions about work.
