I believe in the gospel of cheerfulness, the gospel of Good Nature; the gospel of Good Health. Let us pay some attention to our bodies. Take care of our bodies, and our souls will take care of themselves.

It cannot be too often repeated, that truth scorns the assistance of miracle.

If there be an infinite Being, he does not need our help - we need not waste our energies in his defense.

Religion has not civilized man, man has civilized religion.

If I owe Smith ten dollars and God forgives me, that doesn't pay Smith.

If there is a God, there should be no slaves.
