It is often said in the Bible that God spake unto Moses, but how do you know that God spake unto Moses? Because, you will say, the Bible says so. The Koran says, that God spake unto Mahomet, do you believe that too? No. Why not? Because, you will say, you do not believe it; and so because you do, and because you don't is all the reason you can give for believing or disbelieving except that you will say that Mahomet was an impostor. And how do you know Moses was not an impostor?
Thomas PaineIn Deism our reason and our belief become happily united. The wonderful structure of the universe, and everything we behold in the system of the creation, prove to us, far better than books can do, the existence of a God, and at the same time proclaim His attributes.
Thomas PaineThe prejudice of unfounded belief often degenerates into the prejudice of custom, and becomes at last rank hypocrisy. When men, from custom or fashion or any worldly motive, profess or pretend to believe what they do not believe, nor can give any reason for believing, they unship the helm of their morality, and being no longer honest to their own minds they feel no moral difficulty in being unjust to others.
