All of Them Impostors
Moses, Mahomet, and Jesus, can lay as little claim to moral merit, or to the character of the benefactors of mankind, as any three men that ever lived upon the face of the earth. They were all of them impostors; two of them notorious murderers in practice, and the other a murderer in principle; and their existence united has, perhaps, cost the human race more blood, and produced more substantial misery, than all the other fanatics of the world. --Elihu Palmer (1764-1806), Principles of Nature; or, A Development of the Moral Causes of Happiness and Misery Among the Human Species
