So I’ve been thinking about the argument and the point I made on the greatest possible world in post 1, and I’ve refined that point into what I see as a refutation of the argument. As I noted, the argument assumes that there is such thing as a perfect possible world - or a possible world which meets God’s standards in every possible respect. I, however, would seriously question this - I think that there is no perfect or maximally great world, and that worlds can always in some respect be made better. In light of this, either A5 is false, if we take A5 to refer to a universe which meets God’s standards in every possible respect, or A6 is false, if we take A5 to mean a world that meets God standards in general - for even though some, or even many, aspects of our world may not meet God’s standards, I see no reason to believe that our world in general, taking into account past, present and future, doesn’t. Either way, the argument is unsound.
Now, as I noted, one could counter this and ask why isn’t the world better. But if God only wants to and can create a world that meets his standards in general, and there are infinitely many worlds that meet his standards in general (but none that meet them in every respect), his is free to choose any he wants to create, and is not morally culpable for any deficiencies in the world that arise. So even this form of the argument fails.
Thoughts?
