Liberty is the condition of progress. Without Liberty, there remains only barbarism. Without Liberty, there can be no civilization.

What light is to the eyes - what air is to the lungs - what love is to the heart, liberty is to the soul of man.

Let us put theology out of religion. Theology has always sent the worst to heaven, the best to hell.

Nothing could be more idiotic and absurd than the doctrine of the trinity.

The way to be happy is to make others so.

I found that the clergy did not understand their own book.

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.
