What is the end of human life? It is not, believe me, the chief end of man that he should make a fortune and beget children whose end is likewise to make a fortune, but it is, in few words, that he should explore himself.Who is he that shall control me? Why may not I act and speak and write and think with entire freedom? What am I to the universe, or, the universe, what is it to me? Who hath forged the chains of wrong and right, of Opinion and Custom? And must I wear them? So far as a man thinks, he is free.
