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.

Whatsoever is, is in God.

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.

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.

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.

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

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

The wrath of the lion is the wisdom of God.

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.

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

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.

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