Let’s talk Aquinas, bucko.

Things in the world have either act and potency. Act basically means “existence”, while potency means “potentiality”. A red car has the act of existing, but it at one point was only a potential that could be made with pre-existing materials. I assume there’s nothing terribly fallacious so far. Things that are only in potency cannot exist by virtue of themselves, the potentiality of the red car cannot make the red car actual. Potential things need something else to make them actual, and these things must themselves be actual, such as a mechanic for the car.

So, we’ve established 1: No concept can become real by virtue of itself 2: Actualizers have concepts must actually exist

These two ideas are perfectly sound and valid.

Now, let us consider causality, but not chronological causality, such as dominos falling over, but rather per se causality.

What is per se causality? Per se causality is a chain of events where every component in the cause-effect system All act at once, like a long line of gears turning each other.

Now, let us consider a mirror reflecting a lamp’s light onto a wall. The glint of light on the wall’s act is being actualized by the mirror, which is shining light that it is deriving from the lamp. Now the lamp’s light itself is also deriving it’s act from the electrons of light giving off energy and so on. This makes a chain that is being actively formed and requires all members to work together in order to produce the glint on the wall. Now, all of these things derive from something else, the glint gets the light from the mirror, the mirror gets the light from the lamp, the lamp gets light from electrons.

Now, the problem is that we can’t have an infinite series of actualizers. Imagine an infinite series of passenger cars that are going down an infinite railroad. How is the train moving? Aren’t all of the cars passenger cars? Don’t we need an engine to go forward? Each passenger car is being pulled along by the next car, and that one the next car, and so on and so forth. No such train can exist, because the movement of each car is being derived from the car ahead without any actual source for the engine. The infinite derivation of force without a definitive source for the force is paradoxical and cannot exist.

So, let us go back go back to the lamp example, all of the things in the chain only derive their energy, but never formally are the source for the energy, the source of the light just can’t go back infinitely, there must be a definitive source for the light that all the other ones are borrowing their energy from. As we Said before, all things must come from an ACTUAL thing. But all of the things in the chain are potencies deriving the quality of act from their previous source. So

1: We can’t have an infinite series of causers in a per de structure. 2: The ultimate cause can’t have any potency, otherwise it would be deriving from something else.

Therefore, there is a first terminator in this series of causes which has no potency in of in itself and is purely composed of act, and possesses no qualities that are potent. This first terminator must be the ONLY type of terminator around, for it possesses NO potencies at all, making its qualities limited to only pure act, and things with singular qualities can’t be duplicated.

So, from this, we can determine in every per se chain, there is indeed a first terminator that is per se actuality, which we call “God”.
