Why not deism?

[GrandizerII]

The whole talk about necessity vs contingency can be tricky especially when positing something like modal realism, but the way I look at it is all possible worlds are actualized by necessity because, per the reasoning behind modal realism, you can't have a possible world that is not actual.

If they are spatiotemporally isolated from one another, it does not mean that all these possible worlds aren't part of the same superset world. There is one ultimate actual world in which all these possible local worlds are subsets of, and if they are contingent, then they are contingent on that ultimate world.

The main reason I hold to this view is because I'm a big PSR guy. Why this specific world rather than some other specific world cries for an explanation that traditional theism/deism fails to answer.

It's a really interesting concept; I think it is way more ambitious than classical deism, which really only tries to establish that this world has a reason for its existence, and not really much more than that, unless I'm missing something. I'm thinking of what Antony Flew finally agreed to accept in his latter years: a very, very minimalist "god" — so basic that the word and its connotations could not really be applied to it. There is also the question of teleology; if all possible worlds exist, perhaps teleology is moot.

I was never into that whole thing about teleology anyway.

And you might call this way more ambitious than classical deism, but if one wants to be very stringent with the PSR, then this should be the natural conclusion. Even if you were to argue that the universe exists the way it is because God willed the universe to be such way, one could still ask why did God will it one way but not another?

And I wouldn't agree that this isn't a form of naturalism since I'm not positing a super-being out there that is somehow aware of this reality. I think the only beings that are conscious in this whole reality are entities like you and me, and it probably helps for us to have consciousness. I see no need for the whole cosmos to be conscious, however.

According to my view, there is an orderly hierarchy of levels of reality that logically arises, sure. But it's still all "blind" at the end. No sentient purpose behind it.
