Yes, I see that.
On page 1 of the GAFE II thread, LH wrote:
“Let's take a concrete example. In his defence of Premise 2, bbarr raises the example of a Nazi killing an infant. There are at least two [classes of] alternate states of affairs that could have attained instead:
A1. The Nazi freely chooses not to kill the infant.
A2. God causes some supernatural event to be so that the Nazi does not kill the infant.
We would both agree that (A1) is an instance of R; i.e. A1 > S. But is it logically possible that God can act so that A1 comes to be? If God tampers with the Nazi's free will (so that he chooses not to kill the infant), then this scenario (A1'😉 is not identical with A1 - because the choice of the Nazi is no longer free - what we have is an instance of (A2) instead.
It is logically impossible for God, by any act of His alone, to keep A1 identical to S right up to the point of choice by the Nazi such that the Nazi necessarily freely chooses otherwise. In other words, the only person who could logically cause A1 to attain was the Nazi himself! God is TI1 constrained with respect to this scenario!”
Then the discussion ensued wherein you made the point about libertarian free will.
However, it seems to me that all LH has done—even assuming the coherency of libertarian free will—is show that it is not logically possible for God to cause (A1). I do not see where he shows that (A2) necessarily represents a scenario in which God’s intervention would lead to greater evil (with or without God’s continued intervention in the natural order)—unless, as I noted above, that the violation of free will itself is such an evil. (My response to the question of whether the Shoa is “worth the candle” vis-à-vis free will still stands—
especially if we are talking about an incoherent notion of free will.)
If the standard definition of God’s omnipotence leads to a contradiction (with or without libertarian free will), then a replacement understanding of God’s potency—e.g., what exactly does “maximally potent” mean?—needs to be offered; and the question of why God’s interference would lead to greater evil, while human choice would not, needs to be revisited.
Finally, I do not see the question of
natural evil being answered by the contradiction raised by LH (sorry to refer to you in the third-person here!).
_______________________________
I guess I would be interested in seeing two things here: (1) a revised understanding of God’s potency, with its ramifications for the problem of evil;* and (2) whatever offering LH might have based on another view of free will.
* That is, unless one is content simply to say that God is not able to prevent the evil in the world, and let it go at that, without trying to delineate the limits of God’s potency. As I noted above, one could simply say: “God is powerful, but not all-powerful. There may be circumstances under which humanity can prevent evils that God cannot, and there are evils that neither seems powerful enough to prevent. I trust that God is doing the best [s]he can.”
