Let's move on down Aquinas' list.4. The Argument from from Degree. We notice things in the world differ. There are degrees of, say, goodness or perfection. But we judge these degrees only by comparison with a maximum. Humans can be both good and bad, so the maximum goodness cannot rest in us. Therefore there must be some other maximum to set the standard for perfection, and we call that maximum God.
That's an argument? You might as well say, people vary in smelliness but we can make the comparison only by reference by a perfect maximum of of conceivable smelliness. Therefore there must exist a pre-eminently peerless stinker, and we call him God.
