Whoever imagines himself a favorite with God holds others in contempt.

All I have to say is, Love one another - that is the height of all philosophy. It is beyond all religions. It is the secret of joy - the fountain of Perpetual Youth - the only rainbow on life's dark cloud.

I would rather live with the woman I love in a world full of trouble, than to live in heaven with nobody but men.

Superstition is, always has been, and forever will be, the foe of progress, the enemy of education and the assassin of freedom.

If we should put god in the Constitution there would be no room left for man.

When a man really believes that it is necessary to do a certain thing to be happy forever, or that a certain belief is necessary to ensure eternal joy, there is in that man no spirit of concession. He divides the whole world into saints and sinners, into believers and unbelievers, into God's sheep and Devil's goats, into people who will be glorified and people who are damned.

At the bottom of religious persecution is the doctrine of self-defence; that is to say, the defence of the soul. If the founder of Christianity had plainly said: 'It is not necessary to believe in order to be saved; it is only necessary to do, and he who really loves his fellow-men, who is kind, honest, just and charitable, is to be forever blest' - if he had only said that, there would probably have been but little persecution.
