“Show me the prophet, or any great person who did not possess a rebellious mind and spirit.”

Why I Am An Agnostic (1929)
Context: An agnostic is a doubter. The word is generally applied to those who doubt the verity of accepted religious creeds of faiths. Everyone is an agnostic as to the beliefs or creeds they do not accept. Catholics are agnostic to the Protestant creeds, and the Protestants are agnostic to the Catholic creed. Any one who thinks is an agnostic about something, otherwise he must believe that he is possessed of all knowledge. And the proper place for such a person is in the madhouse or the home for the feeble-minded. In a popular way, in the western world, an agnostic is one who doubts or disbelieves the main tenets of the Christian faith.
