Let us now consider the pair b-l, which takes God to be immutable (unchangeable) and also the creator of the universe. This argument, too, comes in different versions.[4] However, I shall consider just one of them here:
1. If God exists, then he is immutable. 2. If God exists, then he is the creator of the universe. 3. An immutable being cannot at one time have an intention and then at a later time not have that intention. 4. For any being to create anything, prior to the creation he must have had the intention to create it, but at a later time, after the creation, no longer have the intention to create it. 5. Thus, it is impossible for an immutable being to have created anything (from 3 and 4). 6. Therefore, it is impossible for God to exist (from 1, 2, and 5)
Premise 3 might be challenged on the grounds that the loss of an intention through the satisfaction of it is not a genuine change in a being. If a man wants something, X, and then obtains it, he has not thereby changed his attitude towards X. It is not that he once had a pro-attitude towards X but now he has a con-attitude towards it. So long as he is satisfied with X, his attitude remains unchanged. This may very well be true, but why claim that the only genuine change there can be in a being is a change in attitude? Why not allow that there can be other sorts of genuine change, and one of them is the loss of an intention through the satisfaction of it? Until some clear answer to this question is given, premise 3 seems to have some merit.
Premise 4 might be attacked in at least two different ways. It has been claimed that both the concept of "prior to the existence of the universe" and the concept of "God existing within time" are bogus. Time is a part or aspect of the universe itself and so there cannot be a time "before the universe." And God is a timeless being, so the idea of God having a certain property at one time but lacking it at a later time is misguided. Since God is not within time, he cannot have properties at particular times.
My response to both objections is that creation is a temporal concept. This is built into the very definition of "create" as "to cause to come into being." X cannot cause Y to come into being unless X existed temporally prior to Y. Thus, if indeed there was no time prior to the existence of the universe, then it is logically impossible for the universe to have been created. In that case, there could not possibly be a creator of the universe. And, furthermore, if indeed God does not exist within time, then he could not have been the creator of the universe, because, by the very concept of creation, if the universe was created at all, then its creator must have existed temporally prior to it. So if God, being timeless, did not exist temporally prior to anything, then God cannot have been the creator of the universe.
There is another objection to premise 4 which is similar to one we considered in relation to argument 1. It is that 4 would be false if the universe were created unintentionally. Again, it should be mentioned that people who believe that the universe was created also believe that it was created intentionally. But I would like to point out another possible response here. In place of the concept of intention, it would be possible to appeal to some other concept in the construction of argument 2. One candidate for that would be the concept of performing an action. In order for someone to create something, even if it is done unintentionally, the creator must perform an action, and that action must take time. Thus there must be a time during which a creator is performing a certain action and a later time (after the action has been performed) during which he is no longer performing that action. It could be argued that this, too, represents a change in the being who is performing the action. Thus, this would be another reason for maintaining that an immutable being cannot create anything (whether intentionally or not).
