The Worst of Aquinas

The fourth way of St. Thomas Aquinas makes NO SENSE to me! Sure, things are measured by what is greater than the other, but I believe that everyone has their own seperate perception of beauty or knowledge. Its impossible to see eye to eye on the definition of these individual things. As they say, beauty is in the eye of the beholder. As humans we hold our own standards of what we think are right. Although people are extremely judgemental, I dont think we really are able to comprehend the idea of perfection, probably because we have never encountered TRUE perfection. How are we to know God is perfect? The Bible has show us otherwise; God has some jealous and manipulative tendencies. How are we to comprehend that he is perfect then? Perfection is objective, and there is no ruler to how perfect someone is. It is your own belief and opinion.
