God is really only another artist. He invented the giraffe, the elephant, and the cat. He has no real style. He just goes on trying other things.

God is a complex of ideas formed by the tribe, the nation, and humanity, which awake and organize social feelings and aim to link the individual to society and to bridle the zoological individualism.

The various modes of religion which prevailed in the Roman world were all considered by the people as equally true, by the philosophers equally false, and by the magistrate as equally useful.

Educate people without religion and you make them but clever devils.

To doubt everything or to believe everything are two equally convenient solutions; both dispense with the need for thought.

Religion! How it dominates man’s mind, how it humiliates and degrades his soul. God is everything, man is nothing, says religion. But out of that nothing God has created a kingdom so despotic, so tyrannical, so cruel, so terribly exacting that naught but gloom and tears and blood have ruled the world since gods began.

Whatsoever is, is in God.

Religion is by no means a proper subject of conversation in mixed company.

We have just enough religion to make us hate, but not enough to make us love one another.

Without doubt God is the universal moving force, but each being is moved according to the nature that God has given it. He directs angels, man, animals, brute matter, in sum all created things—but each according to its nature—and man having been created free, he is freely led. This rule is truly the eternal law and in it we must believe.

The most dangerous madmen are those created by religion, and people whose aim is to disrupt society always know how to make good use of them.

God is a concept by which we measure our pain.

The state dictates and coerces; religion teaches and persuades. The state enacts laws; religion gives commandments. The state is armed with physical force and makes use of it if need be; the force of religion is love and benevolence.
