Every church pretends to have found the exact truth. This is the end of progress. Why pursue that which you have? Why investigate when you know? Every creed is a rock in running water: humanity sweeps by it. Every creed cries to the universe, "Halt!" A creed is the ignorant Past bullying the enlightened Present. The ignorant are not satisfied with what can be demonstrated. Science is too slow for them, and so they invent creeds. They demand completeness. A sublime segment, a grand fragment, are of no value to them. They demand the complete circle... the entire structure.

Our hope of immortality does not come from any religions, but nearly all religions come from that hope.

There is no evidence that God ever interfered in the affairs of man. The hand of earth is stretched uselessly towards heaven. From the clouds there comes no help.

It is like most other ancient books - a mingling of falsehood and truth, of philosophy and folly - all written by men, and most of the men only partially civilized. Some of its laws are good - some infinitely barbarous. None of the miracles related were performed. . . . Take out the absurdities, the miracles, all that pertains to the supernatural - all the cruel and barbaric laws - and to the remainder I have no objection. Neither would I have for it any great admiration.

Years should not be devoted to the acquisition of dead languages or to the study of history which, for the most part, is a detailed account of things that never occurred. It is useless to fill the individual with dates of great battles, with the births and deaths of kings. They should be taught the philosophy of history, the growth of nations, of philosophies, theories, and, above all, of the sciences.

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.

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.
