A Defense of Classical Theism #10: God: Summing Up

Let's take one final look at how we can reason to the existence of God from the fact that things change and have causal regularity.

Change entails the distinction between actual and possibly, and most things are a composite of how they actually are and how they possibly could be.

If something is composite, it cannot put (and hold!) itself together, because that would mean it simultaneously exist and not exist. Which means something else must hold it together.

That something else is either A) composite, or B) not composite. If A, then something else holds it together as well.

Something must be holding up the whole stack, and that something cannot be composite.

Which means it must be purely actual.

From this drops the classical attributes of God: omniscient, omnipotent, perfect, immaterial, one, timeless, spaceless.

Furthermore, if something aims at a specific goal, as causal regularity entails that things do, this cannot be by chance. However, most of the things that aim at specific end effects or goals are not intelligent. So there must be an intelligence somewhere else that directs these things to their ends.

So from the simply fact science presupposes that change occurs and that there is causal regularity, we can see that there is a God.
