    My concern isn't with existence being or not being a predicate.Michael
    I know, but that article also addresses your concern.

    My concern is with the claim that we can conceive of something greater than God if God doesn't exist (as explained here).Michael
    What do I conceive of when I conceive of God? What do I conceive of when I conceive of this "greater" Being? If there isn't a difference then I don't conceive of something greater than God, and so the premise is false.Michael
    Call X the whole concept of God, including all possible predicates. Now subtract existence from X and call this X-e. The two concepts are existentially equivalent.

    The concept of a pizza in the mind is the same as the concept found in an existing pizza (ideally). That doesn't mean that the predicate of existence does not make a difference though. Clearly the pizza in your mind is different than the pizza in reality, even though their concept is existentially the same.

    Also, if for nothing else, you should also read that article because the ontological argument has played an essential role in philosophy historically. The history of the ontological argument is almost the history of Western philosophy!

    I'm not saying that there isn't a difference between a real X and an imaginary X. I'm saying that if we imagine God to be real then we can't imagine something greater than God, even if God isn't real.

    When we imagine God, we imagine X, not X-e. The ontological argument implies that we imagine X-e, and so can imagine something greater, which is false.

    You think reputable philosophers like Alvin Plantinga would "purposefully" word an argument in a misleading way?Agustino

    That Alvin Plantinga is in any way reputable is an indictment on the intelligence of our species.

    Regardless of that, I don't think the argument is misleading. That a cake exists in the understanding does not tell me whether or not it (being finite) also exists in realityAgustino

    I've given reasons why the formulation is grammatically suspect, reasons which you've not addressed. Brute insistence does not a discussion make.

    No, we're not. This is something that is involved in understanding the concept of God, so that we can say that such a concept is present in the understanding.Agustino

    It also has nothing to do with the syllogism at hand, so has zero import on the argument. I will ignore any argument by you that invokes this pseudo-distinction.

    The only explanation I can see for your behaviour is that you think an appropriate response to the ontological argument is immediate dismissal through ridicule with the purpose of derailing the thread into a flame war.fdrake

    No, that would be your intention.
    You seem to see everything as a confrontation.

    This part is okay, without the ending.

    No, it's not false starting from the assumption of the ontological argument. You keep claiming that we imagine X and not X-e, but that's not what the argument claims.

    These statements say more about you than about Plantinga. It's okay to disagree with someone, but I don't see why you insult his intelligence. He is a reputable, published scholar, a professional philosopher with a PhD from Yale, who also studied at Harvard and other prestigious institutions. On the other hand, I'm not sure where the two of you learned philosophy.

    Brute insistence does not a discussion make.StreetlightX
    Sure, but I didn't insist. I merely quoted you saying that:
    That a cake 'exists in the understanding' means precisely that the cake doesn't exist, or rather, what exists is the 'understanding' of a cake.StreetlightX
    And then explained that the existence of a cake in the understanding does not "mean precisely that the cake doesn't exist", because it could very well exist.

    I've given reasons why the formulation is grammatically suspect, reasons which you've not addressed.StreetlightX
    Your so-called "reasons" mask presuppositions that you have not bothered to make transparent.
    the understanding of the cake, and not the cake, is the subject of the sentence.StreetlightX
    For example, as if there was no connection between "the understanding of the cake" and "the cake". "The understanding of the cake", for example, exists in the cake. That is why experiencing the cake can help me form the concept of the cake in my understanding. You are adopting what looks like a form of nominalism, that entirely divorces the two, such that saying something about the one has no bearing on the other.

    Brute insistence does not a discussion make.StreetlightX
    Sure, of course it doesn't. Neither does calling something a sophism repeatedly, saying that even a 10 year old could understand it, deriding people who hold those views, etc. make a discussion. That might be a monologue though, which helps you feel that you're right and your opponents have nothing useful to say. It kind of betrays the purpose though - if you're so confident, there's no need to deride the opposition.

    It also has nothing to do with the syllogism at hand, so has zero import on the argument. I will ignore any argument by you that invokes this pseudo-distinction.StreetlightX
    At first, you said it has everything to do with the syllogism:
    As for the hand waving distinction between 'finite and 'infinite beings', that's just what you're trying to proveStreetlightX
    Now it seems you have suddenly changed gears, now it has absolutely nothing to do with the argument. So it seems to me that you're quite confused. What I said is important, because having an idea of God in the understanding is one requirement for the argument. And part of having an idea of God in the understanding involves understanding the difference between finite beings, and the infinite Being. This was part of the Hegelian criticism of Anselm, that Anselm never actually clarified the concept of God.

    You keep claiming that we imagine X and not X-e, but that's not what the argument claims.Agustino

    I know that's not what the argument claims. That's the problem. The argument is wrong. We imagine God to be real, even if he isn't.

    No, it's not false starting from the assumption of the ontological argument.

    The assumption is "God doesn't exist in reality". But that's not the same thing as "God is imagined to not exist in reality". The argument conflates, which is why the argument fails. To repeat what I said earlier:

    God is defined as a being than which none greater can be imagined. If a being that is imagined to exist in reality is greater than a being that is imagined to exist in understanding alone then the first premise of the argument is:

    1) [A being that is imagined to exist in reality ... ] exists in the understanding, but not in reality.

    We can't imagine something greater than [A being that is imagined to exist in reality ... ]. 5) is false, and so the argument fails.

    No we don't. We just become aware that God existing in reality is greater than God (existing only in the understanding). That's not the same as imagining a non-existent thing as existing.

    The assumption is "God doesn't exist".Michael
    No, that's not the assumption. The assumption is that God exists in the understanding (not in reality).

    5) implies that the bit in brackets is X-e, which is wrong.Michael
    No, it's not wrong - it actually is X-e in (1).

    1) [A being that is imagined to exist in reality ... ] exists in the understanding, but not in reality.Michael
    No.

    (1) God exists in the understanding, but not in reality.

    Or

    (1) A being than which none greater can be imagined exists in the understanding, but not in reality.

    And I actually agree that we cannot carry out the argument, but not because the argument is faulty, but rather because of our finitude. As radically finite beings, we cannot form the idea of God in our understanding. So we cannot have the idea of God in the understanding that is presupposed in order to carry out the argument. Nevertheless, the argument does an excellent job at displaying our finitude, and providing us with something to attach our faith to - our hope for something unseen, that our minds are incapable of grasping.

    (1) A being than which none greater can be imagined exists in the understanding, but not in reality.Agustino

    And what properties do we imagine a being than which none greater can be imagined to have? Is "existence in reality" one such property? Then we're imagining X, not X-e.

    Yes, that comes later in the argument, where we see that if God is the being than which none greater can be imagined, then existence must also be one such property, CONTRARY to (1), which is an assumption that is later rejected in the conclusion.

    Then it is what I crossed-out earlier:

    The argument only shows that a being who is imagined to be real and have God's properties is greater than a being who is imagined to be imaginary and have God's properties. But there's no way to deduce from this that there is a being who is real and has God's properties.

    If you can read 'hand waving' as 'everything to do with', then I suggest you brush up on your comprehension skills.

    For example, as if there was no connection between "the understanding of the cake" and "the cake".Agustino

    Irrelavant. What exists is the understanding of God, not 'God in the understanding', with is just an ungrammatical obfuscatory piece of sophistry.
