Do not tell me that you have got to be rich! We have a false standard of greatness in the United States. We think here that a man must be great, that he must be notorious; that he must be extremely wealthy, or that his name must be upon the putrid lips of rumor. It is all a mistake. It is not necessary to be rich or to be great, or to be powerful, to be happy. The happy man is the successful man. Happiness is the legal tender of the soul.Joy is wealth.

I love to think of the whole universe together as one eternal fact. I love to think that everything is alive; that crystallization is itself a step toward joy. I love to think that when a bud bursts into blossom: it feels a thrill. I love to have the universe full of feeling and full of joy, and not full of simple dead, inert matter, managed by an old bachelor for all eternity.

Every man who expresses an honest thought is a soldier in the army of intellectual liberty.
