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

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

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

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.

To place oneself in the position of God is painful: being God is equivalent to being tortured. For being God means that one is in harmony with all that is, including the worst. The existence of the worst evils is unimaginable unless God willed them.

The Church says that the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in the shadow than in the Church.

God is a concept by which we measure our pain.

I can’t see (or feel) the conflict between love and religion. To me they’re the same thing.

An irreligious man is not one who denies the gods of the majority, but one who applies to the gods the opinions of the majority. For what most men say about the gods are not ideas derived from sensation, but false opinions, according to which the greatest evils come to the wicked, and the greatest blessings come to the good from the gods.

The nature of God is a circle, of which the center is everywhere and the circumference is nowhere.

Whatsoever is, is in God.

The freedom or immunity from coercion in matters religious, which is the endowment of persons as individuals, is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself.

If God did not exist, it would be necessary to invent him.
