"Are we assured that there are two things which lead men to believe in the Gods, as we have already stated? What are they? One is the argument about the soul, which has been already mentioned — that it is the eldest and most divine of all things, to which motion attaining generation gives perpetual existence; the other was an argument from the order of the motion of the stars, and of all things under the dominion of the mind which ordered the universe. If a man look upon the world not lightly or ignorantly, there was never any one so godless who did not experience an effect opposite to that which the many imagine. For they think that those who handle these matters by the help of astronomy, and the accompanying arts of demonstration, may become godless, because they see, as far as they can see, things happening by necessity, and not by an intelligent will accomplishing good."
