The roles of art, morality, religion, political faith, science itself are not to repair organic exhaustion nor to provide sound functioning of the organs. All this supraphysical life is built and expanded not because of the demands of the cosmic environment but because of the demands of the social environment.

There is a collective as well as an individual humor inclining peoples to sadness or cheerfulness, making them see things in bright or somber lights. In fact, only society can pass a collective opinion on the value of human life; for this the individual is incompetent.

One cannot long remain so absorbed in contemplation of emptiness without being increasingly attracted to it. In vain one bestows on it the name of infinity; this does not change its nature. When one feels such pleasure in non-existence, one's inclination can be completely satisfied only by completely ceasing to exist.

A religion is a unified system of beliefs and practices relative to sacred things, that is to say, things set apart and forbidden-beliefs and practices which unite into one single moral community called a Church, all those who adhere to them.

Man's characteristic privilege is that the bond he accepts is not physical but moral; that is, social. He is governed not by a material environment brutally imposed on him, but by a conscience superior to his own, the superiority of which he feels. Because the greater, better part of his existence transcends the body, he escapes the body's yoke, but is subject to that of society.

When mores are sufficient, laws are unnecessary. When mores are insufficient, laws are unenforceable.
