“Never get angry. Never make a threat. Reason with people.”

Why I am an atheist? (1930)
Context: Any man who stands for progress has to criticize, disbelieve and challenge every item of the old faith. Item by item he has to reason out every nook and corner of the prevailing faith. If after considerable reasoning one is led to believe in any theory or philosophy, his faith is welcomed. His reasoning can be mistaken, wrong, misled and sometimes fallacious. But he is liable to correction because reason is the guiding star of his life. But mere faith and blind faith is dangerous: it dulls the brain, and makes a man reactionary.

Context: There are certain things in which one is unable to believe for the simple reason that he never ceases to feel them. Things of this sort— things which are always inside of us and in fact are us and which consequently will not be pushed off or away where we can begin thinking about them— are no longer things; they, and the us which they are, equals A Verb; an IS.
