A Manichæan, hearing the Atheist, says to him: You are mistaken. Not only is there a God, but there are necessarily two. It has been fully proved that the universe is arranged intelligently, and there is an intelligent principle in nature; but it is impossible that this intelligent principle, which is the author of good, should also be the author of evil. Evil must have its own God. Zoroaster was the first to proclaim this great truth, about two thousand years ago; and two other Zoroasters came afterwards to confirm it. The Parsees have always followed, and still follow, this excellent doctrine. Some wretched people or other, called the Jews, at that time in bondage to us, learned a little of our science, together with the names of Satan and Knatbul. They recognised God and the devil; and the devil was so powerful, in the opinion of this poor little people, that one day, when God had descended into their country, the devil took him up into a mountain. Admit two gods, therefore; the world is large enough to hold them and find sufficient work for them.
