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

The idea that there is a God who rewards and punishes, and who can reward, if he so wishes, the meanest and vilest of the human race, so that he will be eternally happy, and can punish the best of the human race, so that he will be eternally miserable, is subversive of all morality.

If God created the universe, there was a time when he commenced to create. Back of that commencement there must have been an eternity. In that eternity what was this God doing? He certainly did not think. There was nothing to think about. He did not remember. Nothing had ever happened. What did he do? Can you imagine anything more absurd than an infinite intelligence in infinite nothing wasting an eternity?

Laughing has always been considered by theologians as a crime.

If a man would follow, today, the teachings of the Old Testament, he would be a criminal. If he would follow strictly the teachings of the New, he would be insane.

I have no reverence for any book that teaches a doctrine contrary to my reason; no reverence for any book that teaches a doctrine contrary to my heart; and, no matter how old it is, no matter how many have believed it, no matter how many have died on account of it, no matter how many live for it, I have no reverence for that book, and I am glad of it.

Let us account for all we see by the facts we know. If there are things for which we cannot account, let us wait for light. To account for anything by supernatural agencies is, in fact to say that we do not know. Theology is not what we know about God, but what we do not know about Nature.
