arfa brane:
Thanks for the link. That article is written by Craig and seems to be quiet a good presentation of his Kalam Cosmological Argument. Probably he has slightly modified it from his original version in an attempt to address some of the objections that have been raised.
For completeness, I'll post all steps and conclusions from the bottom of that article:
1. Whatever exists has a reason for its existence, either in the necessity of its own nature or in an external ground.
2. Whatever begins to exist is not necessary in its existence.
3. If the universe has an external ground of its existence, then there exists a Personal Creator of the universe, who, sans the universe, is timeless, spaceless, beginningless, changeless, necessary, uncaused, and enormously powerful.
4. The universe began to exist.
5. Therefore (from 2 and 4), the universe is not necessary in its existence.
6. Therefore (from 1 and 5), the universe has an external ground of its existence.
7. Therefore (from 3 and 6), there exists a Personal Creator of the universe, who, sans the universe, is timeless, spaceless, beginningless, changeless, necessary, uncaused, and enormously powerful.
In the context of the objection I raised in the opening post of this thread, above, the same issue is found in premise 2 here.
Specifically, premise (2) creates a distinction between "whatevers" that "begin to exist" and "whatevers" that do not begin to exist. And before we start arguing about "whatevers" vs "things" vs "totalities" and the like, I note that clearly Craig includes God in the "Whatever" in (1) and (2).
The same question arises:
is there anything apart from God (Craig's "Personal Creator") that did not begin to exist?
If so, then premise (3) needs to be modified to include the possibility of some other thing that did not begin to exist being the "external ground of existence" for the universe.
If not, then premise (2) begs the question by implicitly assuming the existence of God, which is what the entire argument is supposed to prove.
---
In (2), by "necessary" I think Craig is asserting that anything that "begins to exist" could conceivably either exist or not exist. This is so as to exclude the possibility raised in Craig by (1) that the universe exists by reason of its own nature. On the other hand, Craig wants to do the opposite with God. He wants to claim that there can be no "external ground" for God, and that God exists due to his own nature (and thus is "necessary"). Note that Craig also sneaks in the "necessity" of God in his most dubious premise (3).
For now, I would still like to concentrate on the
validity of the argument rather than addressing the huge problems of the
soundness or otherwise of the various premises.
Anyway, the main point with this is that nothing has fundamentally been added or changed about the Kalam Cosmological Argument as I originally presented it. The above argument is equivalent, only slightly more explicit. Its assumptions are in there more clearly that the version (also from Craig) that I originally presented. Note that premise (3), in particular, still relies on other arguments that Craig does not make explicit here (although he does refer to them in the linked article).
