Action without thought is mindlessness, and thought without action is hypocritical.

Since reason is man’s basic means of survival, that which is proper to the life of a rational being is the good; that which negates, opposes or destroys it is the evil.

The purpose of man's life...is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question.

At first, man was enslaved by the gods. But he broke their chains. Then he was enslaved by the kings. But he broke their chains. He was enslaved by his birth, by his kin, by his race. But he broke their chains. He declared to all his brothers that a man has rights which neither god nor king nor other men can take away from him, no matter what their number, for his is the right of man, and there is no right on earth above this right. And he stood on the threshold of freedom for which the blood of the centuries behind him had been spilled.

Man has a single basic choice: to think or not, and that is the gauge of his virtue. Moral perfection is an unbreached rationality-not the degree of your intelligence, but the full and relentless use of your mind, not the extent of your knowledge, but the acceptance of reason as an absolute.

I don't wish to be the symbol of anything. I'm only myself.

Since religion is a primitive form of philosophy — an attempt to offer a comprehensive view of reality — many of its myths are distorted, dramatized allegories based on some element of truth, some actual, if profoundly elusive, aspect of man's existence.
