Your thoughts? This actually will lead to another very big question.
I think arguments centered on the paradox of the stone are unsound. For instance, the argument could be delivered in the following way:
(1) Either it is the case that X can create a stone X cannot lift or it is not the case that X can create a stone X cannot lift.
(2) If it is the case that X can create a stone X cannot lift, then X cannot be omnipotent (because X's power would be limited: in particular, X cannot lift the stone in question).
(3) If it is not the case that X can create a stone X cannot lift, then X cannot be omnipotent (because X's power would be limited: in particular, X cannot create the stone in question).
(4) So, X cannot be omnipotent.
In this argument, I think (2) is true (this is the horn of the supposed dilemma that I think actually cuts), but I think (3) is false. I like an article written by C. Wade Savage on this (entitled I believe Paradox of the Stone), in which he does a thought experiment....He says, look, consider you have some entity E1 and some entity E2. E1 can create stones of any poundage or size or shape, etc, and E2 can lift stones of any poundage or size or shape, etc. So, E2 can lift any stone that E1 creates. So it is not the case that E1 can create a stone that E2 cannot lift. But, surely this fact should not really count against the stone-creating power of E1. Now, imagine that E1 and E2 are the same entity.
Or the argument could be delivered in this way:
Objector: "Okay, let's suppose, as you claim, that G is omnipotent. Now, could G create a stone He Himself cannot lift?" (with intent to usher in a dilemma.)
But there is no actual dilemma: the theist can simply respond "No" on the basis that such a stone is a logically impossible object and that he is not committed to a view of omnipotence that entails the power to bring about logically impossible objects (If, on the other hand he is committed to such a view, then I think his view of omnipotence has major incoherency problems anyway).

For full disclosure, the above, word for word, was already posted by me a while ago in the following thread that I started on the subject of omnipotence:
Thread 134210.
That thread I started was not about the rock question, per se, but I brought up the rock question to make a different point regarding the potential difficulty of coming up with a satisfactory notion of 'omnipotence'. I honestly still have little idea how to come up with a formal rendering of 'omnipotence' that I would find satisfactory. Formulations like "omnipotence is the ability to do anything that is logically possible" get by under many discussions; but these formulations seem to fail under deeper scrutiny.
