If your little savage were left to himself and be allowed to retain all his ignorance, he would in time join the infant's reasoning to the grown man's passion, he would strangle his father and sleep with his mother.
Denis DiderotIt is not the man who is beside himself, but he who is cool and collected,--who is master of his countenance, of his voice, of his actions, of his gestures, of every part of his play,--who can work upon others at his pleasure.
Denis DiderotOne must be oneself very little of a philosopher not to feel that the finest privilege of our reason consists in not believing in anything by the impulsion of a blind and mechanical instinct, and that it is to dishonour reason to put it in bonds as the Chaldeans did. Man is born to think for himself.
