This post is one of a serious that picks apart the arguments for god that can be found at the link below. This post addresses number 1:
If you don’t want to click over there to read it, the full argument goes like this:
1. The Argument from Change
The material world we know is a world of change. This young woman came to be 5’2″, but she was not always that height. The great oak tree before us grew from the tiniest acorn. Now when something comes to be in a certain state, such as mature size, that state cannot bring itself into being. For until it comes to be, it does not exist, and if it does not yet exist, it cannot cause anything.
As for the thing that changes, although it can be what it will become, it is not yet what it will become. It actually exists right now in this state (an acorn); it will actually exist in that state (large oak tree). But it is not actually in that state now. It only has the potentiality for that state.
Now a question: To explain the change, can we consider the changing thing alone, or must other things also be involved? Obviously, other things must be involved. Nothing can give itself what it does not have, and the changing thing cannot have now, already, what it will come to have then. The result of change cannot actually exist before the change. The changing thing begins with only the potential to change, but it needs to be acted on by other things outside if that potential is to be made actual. Otherwise it cannot change.
Nothing changes itself. Apparently self-moving things, like animal bodies, are moved by desire or will—something other than mere molecules. And when the animal or human dies, the molecules remain, but the body no longer moves because the desire or will is no longer present to move it.
Now a further question: Are the other things outside the changing thing also changing? Are its movers also moving? If so, all of them stand in need right now of being acted on by other things, or else they cannot change. No matter how many things there are in the series, each one needs something outside itself to actualize its potentiality for change.
The universe is the sum total of all these moving things, however many there are. The whole universe is in the process of change. But we have already seen that change in any being requires an outside force to actualize it. Therefore, there is some force outside (in addition to) the universe, some real being transcendent to the universe. This is one of the things meant by “God.”
Briefly, if there is nothing outside the material universe, then there is nothing that can cause the universe to change. But it does change. Therefore there must be something in addition to the material universe. But the universe is the sum total of all matter, space and time. These three things depend on each other. Therefore this being outside the universe is outside matter, space and time. It is not a changing thing; it is the unchanging Source of change.
Apparently the author has never observed a cell under a microscope, or bothered to understand the 2nd law of thermodynamics. The universe that we are within is under constant change and there is no evidence of external activity interfering with it. As it currently stands, we are unable to detect anything that is outside of this universe. The premise of this argument, that everything needs something external to it in order for it to change, is extrapolated to such an extreme that it makes a fatal assumption. I imagine that the author assumes that we’ll never ‘see’ outside the universe and therefore can’t directly challenge the argument.
If an argument is framed in such a way that it can’t be challenged, does that make it automatically correct?
Physicists are working on the problem of what could be beyond the boundary of the universe, if indeed there is such a thing. There are hypothesis that are in the works and experiments are being devised. For a stack load, and I do mean a stack load, of further reading on the subject, this Wikipedia page has a bunch of references that can be followed (https://en.wikipedia.org/wiki/Observable_universe). Yes, I know there are many who detest Wikipedia for various reasons, it is however a good way to find a list of references to science stuff. So if reading the Wikipedia article makes you want to retch, skip to the bottom and browse through the references. It’s a very good a place to start.
This argument also makes reference to an animal’s will as the external source of it’s desire to move. The will is what we call the decision to move, which is based on the chemical and biological interactions in the brain. The brain, being part of the animal in question, is entirely within the animal and contains nothing that is outside of the animal. The whole idea that our will to move is external to ourselves is an utter nonsense point and factually incorrect.
As will become clear as I chug my way through these arguments, I put a lot of store in what can be explained and demonstrated, which normally means something scientific. The argument quoted above explains nothing and demonstrates even less. It is founded on a crude and minimally descriptive premise and flops downhill from there. There are not even any references to support the points made.
The agent of change that the argument says must exist outside the universe is not explicitly identified in the argument, but we all know that a Christian wrote the item and the only external being that the author is going to accept is the Christian god. The fact that other religions can, and probably do, use a similar argument to this to lead to their own god or gods should be an indication of weakness of this one.
