I agree, by the way. This is exactly what I thought your central argument was. What confuses me is your continuing to cling to it after it has clearly been refuted. But perhaps it is my fault. Perhaps my refutation was not clear enough. I relied — silly me — on the precision of mathematics, and thought that would be sufficient. I can see now that mathematics is not your strong suit, so I will attempt, yet again, to explain to you how your argument fails, but using words instead of numbers.
OK, now, first of all, you have to admit, you are being very slippery in your definition of a “world.” But, I am going to treat that as irrelevant and address your scenario directly, without bothering to pin you down to a more precise definition of a world. My prediction, Alas! is that you will object that I am not using it correctly. To at least attempt to stave off that eventuality, I am going to treat it in several possible ways and demonstrate that they all come out to the same thing in the end, and not what you wanted.
A possible world with only an immutable being. How can this world possibly change?
The straightforward answer: the immutable being could create something.
But, you object, that would be a change in the . . .?
What is your objection?
A. “. . .that would be a change in the immutable being!”
No. It would only be a change in the world in which the immutable being is.
B. “. . .that would be a change in the immutable world!”
Yes, but not in the immutable being. The world with the being in it is not the same as the being that is in the world.
After this, of course, you move the goalposts. It is no longer a possible world with only an immutable being, it is a possible world that IS an immutable being.
I pointed out that that is pantheism. I don’t think you answered that. But clearly, equating the world with God is pantheism. I asserted, further, that it remains pantheism whether or not there is anything else besides God in this world. I don’t think you answered that. But it remains that, in order to assert that
God cannot change → the world cannot change,
you need to assign
God = the world.
I don’t think there is another way to make it come out like that, and if that is indeed how you are doing it, then whatever you are addressing has nothing whatsoever to do with Saint Thomas Aquinas. In order to refute Saint Thomas, you’ll first have to begin to address him. So we can’t waste our time refuting pantheistic deities, and consequently,
God = the world
has got to go.
It then raises the question, without
God = the world,
how are you getting
God cannot change → the world cannot change?
It is worth asking, what is a world? You say, “a possible state of affairs.” You say there is a possible state of affairs wherein God alone exists. I agree, this is a possible state of affairs. You say, in this possible state of affairs, God cannot create. I say, “why?” and you say, because in order to create, He would have to change the state of affairs from Himself alone existing, to a world with a Creation. I say, yes, just so, so what? And you say,
- God is immutable
- God alone exists in this world
- Therefore the world as a whole is immutable
- In order to create, God has to change the world
- But that contradicts 3, therefore,
- God cannot create.
The problem is your confusion by which you move from 2 to 3. God alone in a world does not mean that the world as a whole is immutable. God is not the same as the world. Even if God is alone in the world, He is still not the same as the world.
But! — you object — there is nothing in this world at all except for God! Therefore every property God has, the world as a whole has. God is the whole world!
Wrong. “God is the whole world” is pantheism, and Saint Thomas is not a pantheist.
But! — you object — you are magically creating a fictitious entity, “the world,” when the world I am talking about is merely a possible state of affairs wherein God alone exists!
No. Wrong. I am acknowledging your “possible state of affairs,” in not only one but in two possible and different ways, and it comes out the same either way.
Suppose, first of all, that God alone exists. Then, God creates. He is no longer alone. We have not invoked any “worlds” at all.
Suppose, instead, that there is some world that is empty apart from God. God and nothing else. Then, God creates. Then, there are other things in the world with God. The world has changed. God hasn’t changed, but the world has changed. How is this possible, given that the world is defined as containing God alone? Simple. The world contains God and all that is not God, even when that is nothing at all. After God creates, then it is something, but the same still applies.
Your fallacy seems to hinge on pantheism. But of course, if you fail to make God and the world identical, then you lose the idea that the world cannot change if God can’t change, and you are left nearly ready to admit that maybe God can create after all.
