This is one of the most complex issues there is,especially Hartshorne's version which I use,or one similar to his. On Victor Reppert's Dangerous Idea Blog I found our old friend Stardust makimng the claim that there are no valid arguments for God. As it turns out he didn't know what valid meant. He didn't know in logic it refers to the technical presentation of the argumet Arguments must be both valid and sound, soundness refers to truth. After dancing around that for a bit I decided to just challenge him to debate the modal argument
My argument:
1. God is either necessary or impossible.
2. God can be conceived without contradiction.
3. Whatever can be conceived without contradiction is not impossible.
4. God is not impossible.
5. God is necessary.
6. That God's existence is necessary is a good reason to believe that God is real.
7. Therefore, believe in God's reality is warranted.
Notice I don't say god's "existence," Those of you who follow my blog and have seen my discussion of Tillich will understand this, for the rest of you it';snot important. Notice also that I argue in terms of warrant and not proof. Both Hartshorne and Plantinga refuse to contend they have prove the existence of God but Plantingia argues that the nodal argument is warrant for belief.[1]
Dusty argued:
"IF God exists THEN it is logically necessary that(God exists)"Only in the tautological sense that this statement applies to all existent things. If a thing exists then it is necessary that it exists since it is existent. That makes god nothing special.
Metacrock (me):
wrong, you are not paying attention ,What is being said is that there are only two possibles regarding God's modal status, either necessary or impossible. In other words no middle ground, if God exists he must exist he can't be a maybe, he could not have failed to exist, if there is a God there had to be a God. The only alternative is that if God does not exist it's impossible that God could have existed God either exists and it is necessary that he does or he doesn't exist and if so it's because he could not exit.
Dusty:
If you mean some notion of alternative possibilities that makes god special necessarily then no, one can speculate that something gave rise to god, god's god, but maybe god's god died, though previously greater than god, but now dead, so now god exists.
Meta:
Nope doesn't work that way. God has to be eternal or he can't be at all., he could not have a cause.If God exists he exists as a necessity, A necessity doesn't have a cause,if it did it would be contingent.
Dusty
The speculative alternative formulations are unbounded, hence the assertion of necessity is false.
Meta
wrong modal operators are not "unbounded." Yes there is a limitless field of speculation concerning God but NOT where modal operators are concerned.
Dusty
Fail from the git go, but then, you did not fully define your terms so you might think you have some definitional alternatives to these failings.Meta
Line 3 is a non-sequitur. Just because we can imagine something that does not contradict itself as we imagine it does not mean the reality of the universe can possibly accommodate a realization of that fantasy.
p3 is the lynch pin of the thing, it's anything but irrelevant, the argent turns upon it.
[This argument is about logic and it came in the discussion when we where arguing about validity.So how constriction is regarded in logic really matters.The concept of impossibility is about logical contradiction. Since impossibility is obtained by being illogicality contradictory the lack of contradiction means possibility,]
Dusty
Hartshorne is asserting that mere fantasy is sufficient to allow for external realization. He obviously has a hard time separating fantasy from reality, but that is typical of the theistic mind.Meta
No logician in the world thinks that, he is not saying that,
[He's equating using logic to Establishment of truth by logic with fantasy because he thinks empiricism is the only form of knowledge. As iv say below his position of empiricism as the only true knowledge cannot be proved empirically, He has to use logic to establish probability then to connect probability to empiricism.We know logic can tell us some things about the world. For example we don't have to go look for square circles we know there are none because the concept contradicts itself. For positive understanding of truth content thorough logic see below.]

The whole argument hinges on thinking makes it so, an absurd notion. Why anybody takes this nonsense at all seriously is truly a wonderment for me.
It's so sophomoric to reduce the work of a recognized great thinker to "he thinks thinking makes it so." No he did not think that.He thought that the ontological principle is true. in other words if the terms of a proportion spell out the truth content of the proposition when understood then we have to assume the truth of the argument if the prepositions are valid.
Tillich's example of this principle is that the principle of truth cannot be disputed without admitting to the validity of the principle. One can only say the principle is false if one is willing to admit that truth exists and this principle departs from it, Thus to dispute the truth of truth is to accept the proportion that truth exists. Truth can never be disputed as truth or as sound based upon a logical denial. This is Duane Olson explaining Tillich's view:
The indubitability of the norm of truth is shown by a reductio argument regarding the process of knowing. In different places and in different ways Tillich points out that denial and doubt in knowing presuppose the norm of truth.[17 in the article] I want to systematize Tillich’s reductio argument at this point to show that all major theoretical postures presuppose this norm.

1) “In one of the more significant recent monographs on Tillich’s thought, Langdon Gilkey flatly states “[Tillich] denied that an argument for the transcendent power and ground of being was possible” (Gilkey on Tillich (Wipf and Stock Publishers, 2000), 105). Gilkey never discusses Tillich’s use of the traditional arguments.” (2) “In his detailed and extensive volume on the ontological argument, Graham Oppy mentions Tillich’s name only once in the literature review, and he never analyzes any of Tillich’s statements (Ontological Arguments and Belief in God (Cambridge: Cambridge University Press, 1995), 275). To Oppy’s credit, he discusses a type of argument to which Tillich’s is related. I comment on Oppy’s analysis of this argument in the final section of this paper.”
