So long as one believes in God, one has the right to do the Good in order to be moral.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.

The wrath of the lion is the wisdom of God.

One religion is as true as another.

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

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.

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

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

The important thing, I think, is not to be bitter. You know, if it turns out that there is a God, I don’t think that he’s evil. I think that the worst thing you could say about him is that basically he’s an underachiever. After all, you know, there are worse things in life than death.

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

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.

I believe in an America where the separation of church and state is absolute, where no Catholic prelate would tell the president (should he be a Catholic) how to act and no Protestant minister would tell his parishioners for whom to vote.

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.
