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.

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.

God is a concept by which we measure our pain.

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.

Among all nations, through the darkest polytheism glimmer some faint sparks of monotheism.

Kill a man, and you are an assassin. Kill millions of men, and you are a conqueror. Kill everyone, and you are a god.

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.

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

Reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.

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.

One religion is as true as another.

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.
