I suppose it’s a cop out to say I think you’re both right?
If, as lisaandlena suggest, every past, present and future state of the universe is known to God, then I think there probably is at lease a sense in which all these states actually exist. There might may also be another set of states which include every possible past, present and future state of the universe, regardless of whether they have actually occurred or will actually occur. There is a sense, slightly different from the previous one, in which all these potential (or failed potential) states can also be said to exist. Alternatively, we could simply say that only the ‘Now’ actually exists, and that all the other states are not actual.
- ‘Now’. An actual state we could agree on?
- Past events. These were actual when they were ‘Nows’, but may no longer be.
- Future events. These will be actual when they become ‘Nows’ but may not be at the moment.
- Past possible events which did not, in fact, occur. These never became ‘Nows’, but their very possibility suggest they have an existence of some kind.
- Future possible events which will not, in fact, occur. These will never become ‘Nows’, but their very possibility suggest they have an existence of some kind.
Which if these ‘states of the universe’ is ‘actual’ is a matter of definition rather than reason, I think.
Anyway, from a human (and no doubt other beings) point of view, the universe certainly transitions from one state to another, which we may call change. Even if all the states already in some sense exist unchanging, the transition that I detect is what I call change. The change is not in the states themselves, but the name I give to the transition between them. And surely God appreciates all this, and so to that extent acknowledges that change exists.
