Belief is not a matter of choice, but of conviction.

Every human being should be taught that his first duty is to take care of himself, and that to be self-respecting he must be self-supporting. To live on the labor of others, either by force which enslaves, or by cunning which robs, or by borrowing or begging, is wholly dishonorable. Every man should be taught some useful art.

There are some truths, however, that we should never forget: Superstition has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsistent with mental freedom.

I don't want to hurt people's feelings if I can help it. I don't want anyone unnecessarily humiliated, but I say whatever stands between you and justice must give way; and if you have to walk over reputations — and if they become pavement you cannot help it.

The Old Testament filled this world with tyranny and injustice, and the New gives us a future filled with pain for nearly all of the sons of men. The Old Testament describes the hell of the past, and the New the hell of the future.

If, with all the time at my disposal, with all the wealth of the resources of this vast universe, to do with as I will, I could not produce a better scheme of life than now prevails, I would be ashamed of my efforts and consider my work a humiliating failure.
