Mistake in criticism of Plantinga

This portion is incorrect: Consider premise 3': Maximal greatness is possibly NOT exemplified. It is possible that there be NO being that has maximal greatness. (Premise) Following the same logic, NO omniscient, omnipotent and perfectly good being exists.

Here's the problem: Following the same logic, it does obviously not follow that no omniscient, omnipotent and perfectly good being exists. This has to be deleted.

In case it's not that obvious for you guys:

Plantinga's argument can be summarized as this: (1) It's possible (in a modal sense) that there exists something that has the property of being an F (2) Something is an F if and only if it necessarily exemplifies F* (3) Therefore, there exists something that is an F* (from 1 and 2 + Axiom S5)

In this case, F would be maximal greatness and F* would be maximal excellence.

But even if there's a possible world where F is not instantiated, it does not follow that F* is not instantiated.

Just insert something trivial:

(1) It's possible (in a modal sense) that there exists something that has the property of being a maximal horse (2) Something is a maximal horse if and only if it necessarily exemplifies horse-likeness (3) Therefore, a horse-like being exists (from 1 and 2 + Axiom S5)

Is there anyone here who thinks that horses exists if and only if a maximal horse exists? I hope not. That's why I'll delete that portion.

Beyond whether your criticism is sound or not, Correa's argument was published in an academic article, here is the reference: http://www.worldlibrary.org/articles/ontological_argument

If people find this argument interesting, why not leave it there and let people see it? it has the "citation needed" as well, so it does warn people to be cautious. The argument stands on its merits alone. — Preceding unsigned comment added by 186.27.136.185 (talk) 00:57, 29 August 2014 (UTC)[reply]

If anyone can offer a formal proof that, given Plantinga's premises, maximal excellence is possibly exemplified if and only if maximal greatness is necessarily exemplified and can show me that this does not disprove the existence of horses, restore it. But this won't happen. 84.59.133.76 (talk) 21:13, 22 June 2009 (UTC)[reply]

The problem with your argument is that the term "maximal horse" is entirely ambiguous in its definition. The greatest labor horse is not the greatest race horse. Maximal (greatest) greatness is something conceivable and defineable in the form of something having exhistence contingent on no other exhistence (a quality which could only be held by the greatest being as all other beings have contingent exhistence (I am contingent on my parrent's exhistence, they on their's, etc). Something exhisting this way would obviously contain those elements which make up maximal excelence (for, exhisting alone, one can only be omniscient, omnipotent, and wholly good (this is part of a much larger discussion of God as creator, which I will not go into)). If we replace your ambiguous substitution with one that is definable, say the horse with greatest weight, or the horse with grestest height, your supposed flaw is revealed as a fabrication. Because if any number of horses exhists, one will be taller than the others and therefore be the tallest (if there were only one, it would by default be the tallest). So each quality necessitates the other. You cannot have a heaviest horse without having horses and you cannot have horses without having a heaviest horse. So in a sense, horses really do only exist if there is a heaviests horse because the existence of horses in any number necessitates that there is a heaviest horse. Therefore, the instance horses come into existence, there is in place from their beginning a heaviest horse (or tallest, or whatever other feature) — Preceding unsigned comment added by 174.252.178.201 (talk) 18:25, 14 October 2011 (UTC)[reply]

I ask does it not seem he has created an oxymoron one cannot believe in god because one is god and you prove it by saying that if you can think of it it therefore must exist, therefore you become the god creator.Mysha1959 (talk) 22:21, 29 May 2010 (UTC)[reply]

In Anselm's argument in particular, he is not getting at belief but the knowledge of the highest conceivable being and the falacy of discussing the highest conceivable being in terms of that being not existing. One is never the God creator in terms of the definition of God as the Highest Conceivable Being, as that would make you higher. But you are not the highest conceivable being because you have contingent existence (you are contingent on your parents, and they on their's, etc). The point is that the highest conceivable being exists outside the mind because he must in order to fit the definition. A being that is higher then all other beings must be a being with non contingent existence. Also, all things existing only in the mind are lower than things outside the mind. An imaginary man is not higher than a real man, because if you kill the man imagining the imaginary man, the imaginary man ceases to be. And he is not saying that if you think of something, it must be. He is saying that God, by his definition as the Highest Conceivable Being, must exist in order to fit that definition. Not sure how much that helps; the ontological argument is an odd way to think. — Preceding unsigned comment added by 174.252.178.201 (talk) 18:38, 14 October 2011 (UTC)[reply]

Dysontological argument?

Has anyone ever made an opposite (dysontological) argument against the existence of God such as this:

God is, by definition, a being greater than anything that can be imagined.
However, He would be an even greater being if He could do all that He has done without even existing.
Therefore, ...

It would be a parody, of course. Richard001 (talk) 03:12, 22 June 2008 (UTC)[reply]

I don't know if anyone has ever made this argument in this form, but it is very cool. It reminds me that I have been meaning to add to the refutations of the ontological argument, Nietzche's, which is a kind of existential/psychological refutation: "If God exists, I could not be God. Therefore, God does not exist." Jjshapiro (talk) 03:28, 22 June 2008 (UTC)[reply]

I thought of it myself, though I suspect I am not the first to do so. I say it's a parody, though given that theologians believe things like 'God can see exactly what He will do in the future, although he could have done otherwise', it might warrant serious consideration :)

I do remember something similar in God Delusion, though I think it was someone arguing how God was left with less and less (eventually nothing) to do and needn't even bother existing. Richard001 (talk) 03:39, 22 June 2008 (UTC)[reply]

Although humorous, I fail to see how this contributes to the discussion of the article. I guess if someone collected these lines of thought and made it into a section (or a new article if long enough) then it would be useful. Otherwise the speculation muddies what is already a muddled page of apologetics/anti-apologetics/how-to-improve-article. JECompton (talk) 14:11, 10 July 2008 (UTC)[reply]

I'm curious as to how you use the word tautology here. For the record though I'm a believer I've never been quite convinced of any of the philosophical proofs for God's existence; It's more intuitive for me. That said as I was taught the Ontological proof in college: it ends some thing like, ... therefore 'God exists' is a tautology and tautologies are by definition true, and cannot be rationally denied. You speak here as if a tautology is something absurd. I'd always understood them to be unquestionably true, because the predicate is contained by definition with in the nominative. Of course, tautologies are also considered bad writting for the same reason. —Preceding unsigned comment added by 72.16.146.33 (talk) 16:13, 6 October 2009 (UTC)[reply]

Gaunilo Section Unclear

The paragraph beginning "This response may be inadequate, however..." immediately follows the paragraph by Glenn, but has nothing to do with Glenn's case. It seems like a direct attempt to refute Anselm's argument by quoting Gaunilo. The way it's phrased, it looks like a case of apologetics. Even worse, it is a repetition of the first paragraph of the section. The clarification using the "numbers example" is not only pedantic, but presents a weak analogy (comparison of numbers with islands with God, all without clarifying how these can be formally related). The only merit I see in this passage comes from the organization of Gaunilo's argument in numbered points. Although I usually appreciate numbered lists for clarification, I find the current 1st paragraph of the Gaunilo section sufficiently clear and more expressive than the numbered list in this case. I would recommend deletion from "This response may be inadequate..." to the end of the section. JECompton (talk) 14:33, 10 July 2008 (UTC)[reply]

Why should God have necessary existence?

It seems to me that defining God as "a being who is omnipotent, omniscient and wholly good in all possible worlds" as opposed to merely "a being who is omnipotent, omniscient and wholly good in this world" is not at all well justified. I don't really think that this notion of necessary existence in all possible worlds is what the average person has in mind when talking about God. Unless we have a precise definition of what it means to be "perfect", there's no particular reason to think "perfection" implies "necessary existence". Is a being who exists in other (merely hypothetical) worlds really "better" in any meaningful way than a being who merely exists in this real world?

I suppose one could argue that even if we just define God as "an omnipotent, omniscient, and wholly good being", that proving things about a God who is also necessary is even more significant than simply proving things about God. But I disagree. I can prove by the same logic that if a necessary unicorn is possible, then it must exist. This just follows from S5. But this is far less significant than proving that if unicorns are possible they must exist. Everyone ought to agree that the existence of unicorns is possible in principle (even though that possiblity certainly doesn't seem to be realized in the world in which we are living), so proving that their possibility implies their existence amounts to proving unicorns exist. Whereas the statement "necessary unicorns are possible" is far more dubious, so proving that things are implied from this statement is far less likely to have any bearing on the real world.

It seems obvious that "necessary X are possible" is in general far less likely to be true than "X are possible", since "X are possible" means X exists in at least one possible world whereas "necessary X are possible" means X exists in the whole infinity of possible worlds. To simply assign a probability of 1/2 to a claim that some necessary entity has possible existence based on a total lack of evidence for or against it is only reasonable if you likewise recognize that the uncertainty on this probability is maximal. That is to say, it makes sense to say the probability of X is 1/2 plus or minus 1/2 -- in other words the probability is between zero or one. This of course is no different than saying "We don't have any idea what the probability is". -- Tim314 (talk) 18:16, 7 August 2008 (UTC)[reply]

...I would like to start here and continue with this at another date with the word and terming of God. The example I will pertain to is the possibility of how God came to be, till then.David George DeLancey (talk) 01:48, 31 March 2011 (UTC)[reply]

Nietzsche

Besides his polemics, I remember that Nietzsche had a fairly direct critique of the Ontological argument as it applied to both Christianity and Platonism. Unfortunately, I can't for the life of me recall which book it was from. I'm thinking it was either Genealogy of Morals or Will to Power. Anyway, the quote went something like this: "We see that our world is imperfect, and from there we conclude that there must exist a perfect world." The upshot was that our conceptions of perfection are obtained by simply negating reality and are actually devoid of content.

I think this merits a subsection under "Criticisms and Objections" but I can't really add anything without consulting the source again. Anyone remember where the passage I'm talking about is from? —Preceding unsigned comment added by 74.72.207.114 (talk) 20:19, 19 August 2008 (UTC)[reply]

Cosmological Argument of Leibniz

This section should be deleted. Although a proof of god's existence, it is not the ontological proof, or even related in any way. Any seconds? CancelHoo72 (talk) 03:22, 26 August 2008 (UTC)[reply]

The article as it is, states Leibnitz' argument is a reformulation of Anselm's argument, which i don't see either: one philosophises about necessary causes, the other about the thought of perfection and its consequences, don't really see much of a connection there either. But i think, nonetheless, that Leibnitz' argument is an ontological one, in the sense as the first sentence of the article outlines it. —Preceding unsigned comment added by 84.182.247.76 (talk) 09:03, 27 August 2008 (UTC)[reply]

The article states that it is a cosmological argument. There is a totally separate article for this. I have checked the source and found that it is a paper on the proofs of god in general, not on the ontological proof. As far as being a reworking of Anselm, this is not in the source and it is obvious that it is a reworking of Aquinas. As far as the introductory sentence, the cosmological proof is NOT a priori. This is obvious by the bracketed term [observable]. A priori is "independent of experience." I am removing the offending section.CancelHoo72 (talk) 14:49, 27 August 2008 (UTC)[reply]

Ultimate atheist argument

I just wanted to put this UAA silliness to bed. The ontological argument is that the greatest thing you can imagine must exist outside of your mind as well as be an idea in it, otherwise it's not the greatest thing you can imagine. And then the second postulate is that God is the greatest thing you can imagine because God is by definition the greatest thing, and so therefore God exists. Now not everyone agrees God is the greatest thing you can imagine, and so that's why everyone doesn't accept the argument.

However the UAA is trying to assert, if it really is of the same form as the OA, that the greatest argument you can imagine must also be an argument that exists, that is it exists outside of your mind as well as inside it, and that the greatest argument you can imagine is the UAA. Ignoring the objection that the UAA might not be the greatest thing you can imagine(especially since what that argument might be isn't given at all), the greater problem with it is that AN ARGUMENT CAN NOT EXIST OUTSIDE OF A MIND. An argument is an idea, and ideas only exists in minds, and so the UAA must also only exist inside a mind (or minds). It therefore can not be of the same form as the OA, because you can never assert that there exists an idea which is not exclusively in a mind, no matter how great it is. Plato for instance held that only ideas really exist, but that these are the ideas in the mind of God.

The OA is asserting that the greatest idea you can have must be an idea of something that also exists outside your mind, and so it can't be simply an idea (although it could have ideas if you assert the greatest thing is the greatest mind) and the UAA is asserting there exists an idea so great is exists outside your mind, or any other mind in the universe, as an idea. However an idea is by definition always part of a mind, because only minds have ideas. The OA is talking about something that isn't simply an idea, whereas the UAA is talking exclusively about ideas, and so they are not of the same form and the argument collapses. And you can't weasel out by saying the greatest idea is one so great it doesn't need a mind, because you're now asserting that there is an idea which isn't a thought, and an idea is always a thought. 24.8.102.238 (talk) 05:53, 4 October 2008 (UTC)[reply]

Well...no. I don't for a moment think the UAA is a particularly useful argument against the ontological argument (however, I think Kant puts it away nicely) but the argument is based on the fact that the UAA would be a PROOF that God does not exist. Therefore it would have to be based on some impeccable logic or irrefutable empirical evidence. In that sense, it would not exist merely in the mind, as it would be a manifest quality of the universe that there was no God, if there was a UAA and it was true. The fallacy of the criticism is in fact here: if existence was a predicate, it would be a requirement for a being described as the ultimate, most maximally perfect being. However, the 'greatness' of the UAA would lie in how provable and believable it was. Existence, then, is not a required predicate.

Cartoon deleted

Link to a cartoon example of the ontologial argument was deleted because it clearly misapprehends the actual ontological argument and replaces it with the 1st cartoon character's interpretation of it. Then (sigh) it proceeds with the 2nd character deliberately omitting Descartes' "clearly and distinctly" and then perceives God as a jelly donut (an obvious non-sequitur). Which then magically appears. It baits the audience as rational in the first panel and then irrational in the second. Hence the gag.

Necessary Nonexistence

This section shifts entirely with the criticism of Gasking's argument. In particular, the last section sounds very unprofessional, a bit like a lousy undergrad paper. The section I'm talking about is:

Defenders[who?] of the Ontological argument would of course point out that the above articulation of Gasking's ontological spoof contains 3 rather obvious errors[citation needed]
The first error is premise 3. It would be rather dangerous to objectify something which is completely subjective, in this case being impressed with a 4 year-old composing a symphony.
The second error contained in Gasking's Ontological spoof is premise 4. Of course, non-existence is not an actual property. Only existing things or entities or truths have properties, something cannot have the property of nonexistence.
Going further, the third problem with Gasking's Ontological spoof is that another conclusion must be drawn which is absolutely necessary, and that is the conclusion that God created the world while at the same time not existing. Of course it does not take much reflection to realize that something cannot both create the world and at the same time not exist, for in order to create the world, the very thing which created the world would have to exist.

I think this section should be eliminated and/or integrated in the preceding text. If there's someone that knows much about Gasking's argument, I'd rather they do the rewrite than me. This text could just be deleted, too, which would also be satisfactory, but I don't want to slight critics of Gasking. —Preceding unsigned comment added by Alistaire47 (talk • contribs) 06:59, 26 February 2009 (UTC)[reply]

If I may, I would also point out a falacy of shifting definition on the part of Grasking. He starts with creation as marvelous and then shifts to impressive. What is more imrpessive: A one year old painting a basic human face with proper proportions and decent shading, or the ceiling of the Cistine Chapel? One could easily make the argument for the one year old, as it implies over coming a huge disability, which is impressive. However, which is more marvelous or magnificent? The Cistine Chapel is the most obvious answer. Creation is marvelous because of what it is, not how it was made. The "impressive" aspect is also ambiguous because it could be applied both the the accomplishment and the abilities of the being. The accomplishment of the afore mentioned one year old are more impressive than the chapel, but the abilities of the painter of the chapel are far more impressive than the abilities of the one year old. — Preceding unsigned comment added by 174.252.178.201 (talk) 18:52, 14 October 2011 (UTC)[reply]

Misunderstanding Anselm

This article contains a common mistake. Anselm's argument is cited as:

   1. God is something than which nothing greater can be thought.
   2. God exists in the understanding.
   3. It is greater to exist in reality and in the understanding than just in understanding.
   4. Therefore, God exists in reality

But 4 is incorrect when given Anselm's position:

"Hence, even the fool is convinced that something exists in the understanding, at least, than which nothing greater can be conceived. For, when he hears of this, he understands it. And whatever is understood, exists in the understanding. And assuredly that, than which nothing greater can be conceived, cannot exist in the understanding alone: then it can be conceived to exist in reality; which is greater." - Proslogium, 8

Remember: He's bouncing off of the Psalm, "the fool says in his heart, 'there is no God.'"

By this, the 4 should be:

   1. God is something than which nothing greater can be thought.
   2. God exists in the understanding of the Fool.
   3. It is greater to exist in reality and in the understanding than just in understanding.
   4. Therefore, the Fool conceives of God in reality.

His point is not that God exists because existence is greater than non-existence. Instead, he says:

"There is, then, so truly a being than which nothing greater can be conceived to exist, that it cannot even be conceived not to exist; and this being thou art, O Lord, our God." - Proslogium, 9

His point is that the unique position of God in the mind is evidence that God exists.

The misinterpretation of Anselm is exactly why Gaunilon tried to reply with an insufficient argument. Obviously the concept of a "lost island" does not hold the same uniqueness as the concept of God.

That's also why Kant's "existence is not a predicate" reply is insufficient, Anselm's argument isn't completely ontological; it's epistemic!

But, it has historically been called the Ontological Argument, so here it will remain.

Comments and Concerns will be enjoyed. :)

Thanks for this and the ref - very useful. But, from Anselm, should not your 4 read: "Therefore, EVEN the Fool conceives of God in reality"? This seems to be attempting to persuade us that God exists because even an idiot (or a simple person) can see it's true. Myrvin (talk) 07:11, 13 August 2009 (UTC)[reply]

After more thought, I've gone off my characterisation. I now think this all means that, if the fool can say ‘there is no God’, then he is actually conceiving of God – who he believes, ‘in his heart’, does not exist. But this means that even the fool understands the concept of God, and God – that which nothing greater can be conceived – cannot only exist in the understanding. Therefore, God exists in reality. There should still be an "even" in your number 2 though. Myrvin (talk) 09:10, 13 August 2009 (UTC)[reply]

Unrelated to your main point here, but still under the topic of misunderstanding Anselm: under the revisions portion of the article it states "Obviously St. Anselm thought this argument was valid and persuasive, and it still has occasional defenders, but many contemporary philosophers believe that the ontological argument, as St. Anselm articulated it, does not stand up to strict logical scrutiny.[1]" but this is not true, it unfairly attacks Anselm and what he was trying to do in the Proslogium, on the wiki page http://en.wikipedia.org/wiki/Proslogion, it states that "Anselm wrote this discourse, not from the perspective of an attempt to convince non-Christians of the truth of Christianity, but rather from the perspective of a Christian believer seeking a rationale for his/her faith. His original title for the discourse, in fact, was Faith Seeking Understanding." another note: "As originally formulated by the Christian theologian Anselm (1033-1109), it was not meant to be an argument to prove God's existence; rather, for him it formed a way of understanding the God in whom he already believed." (Peterson, 92, ISBN 987-0-19-533599-6) anyway i think it should not state the Anselm thought it was obviously valid and persuasive, but i was not sure how that sentence and the change of section should be handled so i leave it up to you to decide. —Preceding unsigned comment added by 71.237.193.44 (talk) 01:36, 20 April 2010 (UTC)[reply]

Anselm's argument was that the only greater thing that a person can conceive of is something in their conceptions plus the reality of that concept? This makes no sense, since in order to possess a full concept of god a person would have to be as perfect as god; how else could they form an accurate concept? Their concepts would not encompass the full perfection of god, and thus that flawed concept would only lead to an imperfect being which as suggested by Anselm would also lack the necessary perfection of reality.124.168.144.254 (talk) 15:46, 26 February 2011 (UTC)[reply]

Gasking argument

"The third premise might seem odd; the intuition is that we are generally more impressed by, for example, a four-year-old child composing a marvelous symphony than the same composition of a professional."

This example doesn't constitute a valid objection to the third premise. A small child would indeed be severely handicapped in its ability to compose a symphony, as a seasoned professional would have the advantage of a much greater experience in this field. On the other hand, one could argue that a child who could accomplish such a feat must be vastly more talented than the average composer, who could only do so after years of training, and that under these circumstances, it is actually the adult composer who's handicapped. But if we, for example, understood "handicapped" in its medical sense, wouldn't it be much more impressive if a symphony were created by somebody who was born deaf, instead of a person with normal hearing? That's why I'd suggest to remove the lines about criticisms concerning the third premise (unless someone can bring up additional objections), and to start the paragraph with Oppy's critique of the first premise. —Preceding unsigned comment added by 77.56.178.140 (talk) 14:41, 17 June 2009 (UTC)[reply]

Personally I'd have to disagree. If hearing a beautiful symphony and asking what genius wrote it I was told, actually it was written by someone born deaf. I'd be disappointed to realize that someone who didn't truly understand the beauty of what he had created, had accidentally tripped on this beautiful melody. The symphony would be just as beautiful, but the handicap lessens the accomplishment not increases it. It reminds me of when I was in architecture school; a professor said that when he saw a design of what he considered to be great poetry, he was always afraid to ask the student how he arrived at it, because often he'd find the student didn't grasp the true quality of his own design.

I disagree with the disagreement above. Its the professor who saw the magnificence in the creation and no the creator. Similarly, we humans are seeing the magnificence of the creation. It doesn't matter if the creator grasps the beauty in His/Her work. The handicap does not lessen the accomplishment. —Preceding unsigned comment added by 99.228.61.208 (talk) 02:51, 14 May 2010 (UTC)[reply]

Image in bibliography

Pardon me if this is a completely newbie question, but why is there an uncaptioned image in the bibliography? Is it related to the subject of the article, or just illustrating the concept "bibliography"? (If the latter, can it be deleted?) Cancilla (talk) 06:05, 21 June 2009 (UTC)[reply]

Anselm of Canterbury or Avicenna?

The Anselm of Canterbury article claims that "he is famous as the originator of the ontological argument for the existence of God," while this article claims that "Avicenna was the first person to come up with the ontological argument." So which is it?--98.232.98.144 (talk) 03:15, 13 August 2009 (UTC)[reply]

Well, Amselm apparently has the fame for inventing it. 88.68.105.219 (talk) 19:49, 3 September 2009 (UTC)[reply]

Avicenna's argument, while it may contain ontological elements, is primarily a cosmological argument. Anselm's argument is strictly ontological. In philosophy, as an academic discipline, "the ontological argument" refers specifically to Anselm's a priori argument for the existence of God. The Wiki article would be much improved by removing all information not pertinent to the argument in question (this would include the whole section on Avicenna).

Anselm's argument, as found in Proslogion, is actually a reductio ad absurdum: It assumes the opposite of the proposition it aims at proving and then attempts to show that such an assumption leads to a logical contradiction.

1. Nothing greater than God can be conceived (accepted as a premise) 2. People, even the fool, have a conception of God (again premised) 3. If the conception of God does not include existence, then something greater can be conceived--A god which does exist. 4. To conceive God without existence thereby contradicts our first premise.

The simplest counterargument is, without contesting the premises, that of Aquinas: Anselm proves, at best, that an idea of God must include the idea of existence, but this in no way proves that God actually exists.

False dichotomy - Anselm or Avicenna? Actually, neither... Ontological arguments for Divinity's existence are reported in Antiquity: Sextus Empiricus reports that Diogenes of Babylon made such an argument for the gods' existence. There are scholarly articles on this matter if you look for them. e.g. Michael Papazian's "The ontological argument of Diogenes of Babylon" http://cat.inist.fr/?aModele=afficheN&cpsidt=18874067 Emyth (talk) 17:25, 19 February 2011 (UTC)[reply]

Extraneous Content

I have deleted the following sections of the article as they are extraneous to the topic:

Avicenna's Argument--This is actually a cosmological argument derived from Aristotle's Metaphysics.

Shahab al-Din Suhrawardi's Argument--Again, this is a cosmological argument.

Mulla Sadra's Arguments--This is simply a lengthy quote from a work of dubious relevance to the ontological argument.

Problem of Evil--This is, at best, tangentially related to the topic.

Criticism by "essence precedes existence"--These are rebuttals to Avicenna's cosmological argument.

Alexander R. Pruss and Samkara's dictum--This section has only marginal relevance to the main topic and has the appearance of original research.

Apparently Wikipedia won't allow such an extensive edit without somehow verifying that it is not vandalism.

I strongly suggest the content I have mentioned be deleted. The large amount of extraneous or marginally relevant information in the article makes it a poor resource for either the student of philosophy/theology or the interested layperson.

I agree that the Sadra paragraph beginning: "Therefore, if existence is not created through the creation of a creator ..." appears to be the cosmological argument. And the whole section is much too big. I'll have a go at reducing it. Myrvin (talk) 10:24, 16 December 2010 (UTC)[reply]

Other suggestions for improvement

Besides the deletion of extraneous content I also suggest the following changes:

1) "The ontological argument has been a controversial topic in philosophy. Many philosophers...have openly criticized it."

This gives the silly impression that at least some philosophers disagree with the argument but have refrained from openly criticizing it because of its controversial nature.

The article should simply describe the most pertinent criticisms of the argument made by philosophers.

2) In the context of the Abrahamic religions, ontological arguments were first proposed by...

This gives an erroneous impression of the argument's philosophical context and pedigree. Avicenna, Anselm, and company were not only all members of "Abrahamic religions", they were also all heavily influenced by neoplatonism. A proper understanding of the argument requires it be examined in the context of neoplatonic realism. The form of neoplatonism found in medieval Catholic philosophy is largely due to Asian, and especially Islamic (starting with Al-Kindi), philosophers.

These philosophers, in turn, first encountered neoplatonism via the Christian philosopher Boethius (the definition of God used by Anselm in his argument [id quo maius cogitari nequit] is from Boethius) and the pagan philosophers Porphyry and Plotinus.

3) The article would also benefit by a more accurate synopsis of the argument and a direct quote of the argument as found in the Proslogion:

Assuredly, this [being] exists so truly [i.e., really] that it cannot even be thought not to exist. For there can be thought to exist something which cannot be thought not to exist; and this thing is greater than that which can be thought not to exist. Therefore, if that than which a greater cannot be thought could be thought not to exist, then that than which a greater cannot be thought would not be that than which a greater cannot be thought—[a consequence] which is contradictory. Hence, something than which a greater cannot be thought exists so truly that it cannot even be thought not to exist. And You are this [being], 0 Lord our God.

-Proslogion, ch. III. Hopkins

Problem with Problem of Evil

"Some Christians argue that God's justice is easily reconcilable with His mercy: "Mercy in this life; justice in the next."

"The Christian doctrine of Penal substitution reconciles this, however. It argues that Jesus, being both God and man, represented all of humanity when He died on the cross. In his death, God meted out the justice, deserved by humanity, onto Christ so that God could be both completely just and completely merciful. (2 Corinthians 5:21, Romans 3:26)"

Neither of these two represents a viable solution to the problem of evil. The first one doesn't say anything and the second still leaves the fact that God created all evil in the first place when he had (and presumably still has) the power to stop it. Furthermore, how could humanity deserve justice when they were created by God himself who, being omniscient, knew prior to creating them that they were going to deserve his justice? Thus God would have had to condone the evilness that would emerge through us—his creation—and either actively chose to let it be that way or is currently powerless to change it. And those are just a few of the issues. These two replies add nothing to this article and should be removed. --logic— 02:34, 26 October 2009 (UTC) —Preceding unsigned comment added by Nathanmx (talk • contribs)

The problem of evil has no place with the ontological argument. Both are separate religious points/arguments/ discussions. —Preceding unsigned comment added by 82.32.217.177 (talk) 16:39, 7 November 2009 (UTC)[reply]

Both of the comments above are essentially on the mark. There is a weak attempt in this section to link the problem of evil to the ontological argument as follows: versions of the ontological argument require that maximal greatness be possible and (roughly) derive its necessity from its possibility. The existence of evil seems prima facie evidence against maximal greatness and therefore undermines its necessity and thereby is possibility. But this can be stated in a single sentence, and everything else in the section is just cobbled on. In short, the section should be deleted. Cerberus (talk) 00:26, 12 November 2009 (UTC)[reply]

The problem of evil is unrelated to this article. I removed it. By the way, Nathanmx's argument is not very convincing, because it assumes all kinds of things of good and evil for which there is no basis. Most importantly, what is evil or bad anyway? In order to make a muscle grow, it must be subjected to microtrauma, which effectively breaks the muscle, and would be bad as such. Likewise, it could be argued that good simply entails some portion of evil in the very core of the concept. It is possible, therefore, that the end-result of everything (including things we tend to call evil) is indeed the optimal amount good, the ultimate good, goodness in its purest form. There is nothing illogical in this explanation - that God condones what we call "evil" and is still omnipotent and all-good. Ask yourself if there is a maximum amount of good. If you think there is, then that amount (no more or no less) of good is the amount of good that and all-powerful all-good God would (logically) have to create. You cannot estimate whether the the maximum good has been established or not if you do not know how much of the things we call evil that good would entail, and can never know that, so you cannot say, that the evil we experince would be somehow a proof of the alleged fact that the maximum happiness has not been established. Then again if you do not think there is a maximum amount of good but think that "good" is limitless, then we are dealing with some relatively complex concepts of infinity that might appear counter-intuitive to some. If something is limitless, taking something away from it would still have it remain limitless. Likewise, if God was able and willing to create a good mode of existence manifesting limitless goodness, then having some non-good elements withing that existence would not render that goodness any less limitless. So the illogicalities you point are only true with certain assumptions about good and evil that are very questionable. But as I said, this has next to nothing to do with this article, I remove this part. 128.214.164.107 (talk) 15:37, 21 October 2010 (UTC)[reply]

Avicenna

Traditionally,St.Anselm has been credited as the inventor of the ontological argument.I have found no other sources that support the claim that Avicenna was the first to develop this argument.In fact,99% of the sources say St Anselm did.It shold be noticed that Avicenna argument,though it has an ontological basis,is very different from the original argument.And it´s really cosmological(The first paragraph of the section is repedted in the cosmological argument page.

Sentence must be revised or removed

"Classical theism states that God is omnipotent, omniscient, and omnibenevolent, without worrying whether these terms (even assuming they are meaningful) can be coherently jointly asserted."

The first part is untrue because "omnibenevolent" is not a word used by theologians of note. It is mainly used by atheists who wish to disprove God's existence. There are, in fact, no Bible verses to support the idea that God is "omnibenevolent" if that word means giving only good things, and never punishment or trouble. The word "omnibenevolent" does not appear in the Bible, in any language. God is omniscient, omnipotent, holy, righteous, and just. Any thought of God's goodness must be balanced by an understanding of God's justice. http://www.newadvent.org/cathen/14569a.htm

The second part of the sentence is untrue, and completely ignores the millennia of Christian scholarship that have occurred since Jesus was resurrected. Seriously? Have we all not heard of churches splitting, battles fought, people excommunicated, monks arguing and punching each other, and so on, and all over theology? To say that theologians "don't worry" about whether their statements are logicallly consistent is just ignorant. http://philchristi.org/ http://stjrussianorthodox.com/theology.htm http://www.reformed.org/documents/wcf_with_proofs/ http://www.vatican.va/archive/catechism/ccc_toc.htm (etc. etc. ad infinitum!)

Because neither of these statements is true or sourced, I think this sentence should be deleted. The article is just fine without it.

Agreed. The sentence is essentially somebody's personal argument and is irrelevant to the article. Pruss, your recent deletion of a cosmological argument and some miscellaneous original speculation is totally on the mark, IMO. ... Kenosis (talk) 17:53, 11 November 2010 (UTC)[reply]

Bertrand Russell's criticism

-- It has also received its share of criticism from non-Christians: Bertrand Russell noted that "The argument does not, to a modern mind, seem very convincing, but it is easier to feel convinced that it must be fallacious than it is to find out precisely where the fallacy lies." --

This hardly sounds like a criticism. In fact Russell is saying that it is difficult to discover where the argument is fallacious and seems to imply that it may not be fallacious at all. While not rejecting the argument's validity, this quote also does not state that Russell did not believe the argument was sound, which by necessity he must have. I'm sure someone can find a better quote. One that is actually critical to the ontological argument -- not defending its validity. —Preceding unsigned comment added by 97.126.158.140 (talk) 01:35, 5 April 2011 (UTC)[reply]

"this quote also does not state that Russell did not believe the argument was sound, which by necessity he must have" Huh? What necessity? Have you read anything he wrote? Russell was far from any sort of believer, a direct contradiction to the claim he believed this argument sound. To me, you've just engaged in contorted original research; I really don't see how you think this single quote implies Russell thought the argument was sound and supported it.

How about this from "Why I am not a Christian":

I for a long time accepted the argument of the First Cause, until one day, at the age of eighteen, I read John Stuart Mill's Autobiography, and I there found this sentence: "My father taught me that the question, Who made me? cannot be answered, since it immediately suggests the further question, Who made God?" That very simple sentence showed me, as I still think, the fallacy in the argument of the First Cause. If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument.

Name of this article

I believe this article is misnamed. This article should be renamed "Ontological arguments for the existence of God". I was very confused when I read the first sentence of this article: "An ontological argument for the existence of God attempts the method of a priori proof, which uses intuition and reason alone." Indeed, this is merely an EXAMPLE of an ontological argument. An article titled "Ontological Argument" should have more than ONE example of ontological argument and the first sentence should describe what "ontological argument" means. Keep in mind that there are ontological arguments for the existence of the universe or ontological arguments for the existence of certain fundamental rules of physics, and many other examples. 137.122.30.226 (talk) 19:21, 3 November 2011 (UTC)[reply]

I've moved this comment to the bottom of the talk page so that other editors can easily find it. I think that the current title is ok, as the main argument - what is meant by 'the ontological argument' - refers to the argument proposed by Anselm and developed by Descartes. There are then variations, which are detailed further on in the article. I think that that lead needs rewriting, rather than the name changing. I'm currently working on improving the article myself and hope to rewrite the whole of the lead once I've done the rest of the article. Ontological Arguments already redirects here anyway.

Coherence of a maximally great being

The words in this section go much further than the sole cited reference. The latest additions go further still. We need more citations for these assertions and arguments. Also, a definition of "coherence" would be useful. Myrvin (talk) 08:00, 3 January 2012 (UTC)[reply]

I have edited the section to remove the excessive explanation of incompatibility and anchored the reference to the chapter. Everything there now is mentioned in Chapter 4; Section IV of the source (entitled Is the Concept of a Maximally Great Being Coherent?). I have thus removed the {{fact}} template. Hopefully that has dealt with your concern; if not, let me know. ItsZippy ^{(talk • contributions)} 13:00, 3 January 2012 (UTC)[reply]

I doubt if C. D. Broad is so ignorant he doesn't understand the difference between a maximal element and a maximum element. The current wording suggests that C. D. Broad argues that "greatness" is not a linear order, and concludes that the notion of maximal is incoherent. Obviously this would be completely fallacious reasoning: indeed, arguing that "greatness" is not a total order, far from precluding the existence of a maximal element, allows for the possibility of MANY maximally elements. 97.88.244.2 (talk) 03:33, 6 August 2013 (UTC)[reply]

GA

I have finalized my evaluation of this page and have determined that it does meet Wikipedia's Good Article criteria. The page is not under any significant level of internal debate in terms of content, the references check out well and go to reliable and relevant sources. The entry shows a balance of opinion from relevant modern and pre-modern scholars. The history and relevance of the subject matter has been clearly laid out, and a clear explanation of the subject matter has been achieved such that a non-expert could read and learn from the entry. The writing is clear and appropriate for the field which is being written about. There are no obvious copyright issues, and no section of the entry has been plagiarized. During my review the nominator took care to correct problems with citations and an over-reliance on one source (Graham Oppy) that has now been eliminated. By adding additional sources and helping to clarify the Anselm section and others, the article now falls within the bounds of a Wikipedia Good Article.

Ok, in response to your review, I have done the following:

Expanded the McGrath reference
Replaced the reference before the outline of Plantinga's argument with a more reliable reference
Removed an unreliable reference (and with it reference to an unreliable criticism) from the section on Plantinga.

I have not removed the SEP or IEP references, as they are considered reliable sources and are recognised as reliable sources by the Philosophy WikiProject. The article are written by established contemporary philosophers, so I do not think that there is an issue with reliability there. I'm not quite sure what problems you have with sources 37 and 49 (they were 39 and 50 at your review - the numbers have changed). Although the Tim Holt reference isn't totally reliable, it is not supporting anything contentious. I hope you accept my comments - if there's anything else that needs changing, please let me know.

A few more points I'd like to address.

1) The classification section appears to rely too much on Oppy, and is written as if he is the world's foremost expert on the subject matter. It does not take into account the work of other very prominent modern scholars such as Brian Leftow of Oxford University or John Polkinghorne. These are merely examples of the wealth of other opinions out there, which the article does not appear to recognize. At the very least it would be best to include at least one other differing point of view, to avoid the appearance of advocating of behalf of the Monash professor.

2) At the start of the Development section the blurb about Avicenna is written a bit dismissively of those who claim there was an OA before Anselm. It would be better to say that the those views are "in dispute", as it is more neutral language. Not a major thing though.

3) As Anselm's argument is perhaps the most important thing to know about the ontological argument, it would be nice to see a better effort trying to explain the argument in layman's terms in addition to the technical explanation--such as is found later on with the sections on Sadra or Godel. As it stands, the Anselm section is not written clearly enough for someone who does not already know what the OA is to grasp the content of the idea. More time is spent doing so for even Gasking than Anselm, which seems to be an imbalance.

4) No citation follows the block quote in the Sadra section. Citations should follow quotations, not precede them.

5) Again we find Oppy arising in the Godel section. Up until this point he has been the sole modern scholar cited by name in the entry, giving the appearance of either a lack of knowledge of the other modern scholars or undue preference given to his work. So, up until this point, the entry is too reliant on only the work of Oppy.

6) Almond's quotation in the Plantinga's section is now no longer cited whatsoever, so a citation needs to be added.

7) Again we hear from Oppy--at this point his opinions have been given greater weight than many of the people he is writing about. Deference to Oppy needs to be reined in.

8) It is unclear whether or not the reference to Broad is covered in the Dawkins source or only Himma is covered. If both are covered, I think an added citation should go after the Broad reference just to keep things clearer. If not, a citation for Broad needs to be added.

Other than this the piece seems quite well prepared. Jeremy112233 (talk) 16:31, 23 January 2012 (UTC)[reply]

Thank you - that feedback is very helpful. I have dealt with issues 2, 3 and 4. I have started to introduce alternative opinions in the classification section, but am pushed for time right now. I will finish that off and look at the other issues tomorrow evening. Thanks. ItsZippy ^{(talk • contributions)} 19:21, 23 January 2012 (UTC)[reply]

Ok, I've made a few more changes. I agree with your general assessment that the article does feature Oppy quite a lot. He has made substantive contributions to the ontological argument, especially in his classification and analysis of the current arguments (most sources I've found themselves cite Oppy). Nevertheless, you are right that additional viewpoints are required. I have added the views of William Lane Craig and William L Rowe to the classification section, and Daniel Dombrowski's views to the beginning of the development section. There is little academic discussion on Gödel, but I've managed to add something from Robert Maydole. Heopfully that should give a better range of opinions. Gasking still needs additional views - I'll see what I can do there shortly. If there's anything else you think needs improving, let me know. And thank you again for your review - the article seems much better because of it. ItsZippy ^{(talk • contributions)} 20:37, 24 January 2012 (UTC)[reply]

I think the additions are excellent. The Godel issue was simply one of a package of issues revolving around Oppy and on the whole that appears to have been taken care of--I'm okay with leaving the Godel section as is now, as after the addition of the Craig source and the rest of the sources added the issue of deference appears to have been dealt with effectively. The only thing left is that the Almond quotation still does not have a citation, and then I think the article is (in my opinion) ready to be promoted. Jeremy112233 (talk) 01:21, 25 January 2012 (UTC)[reply]

The Paul Almond quote is referenced by source 30. Although I'm aware that the website isn't incredibly reliable and I don't really know who Paul Almond is (or who added the reference) - I'll see if I can find a source & philosopher for that. ItsZippy ^{(talk • contributions)} 19:36, 25 January 2012 (UTC)[reply]

Don't worry about it, the citation just needed to be put back in (I believe it was gone before, maybe I was just seeing things). The Almond reference as its stands should be fine, and they Oppy deference have been alleviated for all intents and purposes. I'll go ahead and make my recommendation now.

Some comments

The article looks good, I'm pretty impressed with how it has come together. I doubt this was an easy subject to research and write about! After reading through I have a few comments:

I noticed in the lead that for some of the philosophers mentioned their century is given, but for others it isn't.
In the lead you start with "Anselm of Canterbury" but then in "Development" you introduce him as "St Anselm".
Be consistent about using dates in the beginnings of the "Development" subsections.
"Sadra discussed Avicenna's arguments for the existence of God, claiming that they were not a priori, and rejected the argument on the basis that existence precedes essence, or that the existence of human beings is more fundamental than their essence." This sentence is a bit long, is there a good way to break it up?
The Sadra quote is fairly long, maybe think about shortening it if there's a good way to do this without losing anything important.
"Mathematician Kurt Gödel provided a formal argument for God's existence. The arguments were constructed by Gödel but not published until long after his death." You switch between the singular and the plural here. Also, could this be condensed to one sentence?
In the Godel section, some of the Definition/Axiom etc. lines end in periods and some don't. Was that intentional?
"Malcolm identified two key arguments of Anselm's second:" second chapter?

"Anselm responded to Gaunilo's criticism by arguing that the argument applied only to concepts with necessary existence." Is there a good way to rephrase this to avoid "arguing that the argument"?
"Aquinas' rejection of the ontological argument caused some Catholic theologians to also reject the argument." Again, there is a bit of repetition in this sentence, any good way to restate it?
Try to be consistent about italics for a priori.
There are a lot of semi-colons, might want to check to make sure none of them are being misused.
Ok, that's basically all I came up with. Some of the sentences were a bit hard to follow, but given that this is such a complicated topic there's only so much that you can do about that, I guess. Mark Arsten (talk) 22:48, 1 February 2012 (UTC)[reply]

Dawkins

An editor has suggested that the few words about Richard Dawkins should be removed because "it seems to me that he doesn't offer anything substantial here." I agree that he is no great philosopher, but people who have read him - and a lot of people have - would expect to see him here. Indeed, it may be because of reading RD that they have looked up this article. I think the newspaper article that is cited is very biased against him and pro the O argument. He says "But if you think that there must be some ultimate explanation for the improbable leaping-into-existence of the harmonious, biofriendly cosmos we find ourselves in, then the God hypothesis is at least rational to adhere to, isn’t it?"

It looks like the writer is doing his own book on the subject, so RD may also be a rival. I will try to include some words from the RD book itself, rather than just use a commentator who is anti his views. Myrvin (talk) 09:34, 15 February 2012 (UTC)[reply]

Dawkins does not provide any criticisms of this argument that haven't already been mentioned in this article. Therefore he adds to this article. Secondly he has no qualifications in philosophy and he is not taken seriously those who have such qualifications. His inclusion in this article detracts from the status of Wikipedia as a respectable encyclopedia. Can you imagine anyone including a quote from Ray Comfort in the evolution article stating that evolution cannot be true because it offends him aesthetically?--HyperEntity (talk) 01:30, 1 August 2012 (UTC)[reply]

Your argument is somewhat undermined by comparing Richard Dawkins to Ray Comfort. That could be seen as detracting from the status of Wikipedia as a respectable encyclopedia too. Just saying'. Sean.hoyland - talk 03:41, 1 August 2012 (UTC)[reply]

No it doesn't. It's a simple fact that that Dawkins' views on philosophy carry as much weight within the philosophical community and as the views of Ray Comfort do within biology.--HyperEntity (talk) 09:48, 1 August 2012 (UTC)[reply]

That isn't "a simple fact", that is a personal opinion (about a number of things including the article content inclusion criteria). Confusing the two is where you are going wrong. What is happening is that you are forcing your personal opinion on other editors. You made an edit, you were reverted, but because you assume you are right you repeated your edit. That isn't how things work here. The editor who reverted you said "I can see no consensus or even discussion about removing this correctly referenced section?". Your response "That you require consensus to remove this absurdity is deeply worrying. See comments on the talk page. Please do not revert this edit as you are vandalising this article and ruining the respectability of this site by doing so" was unhelpful and misinformed. WP:CONSENSUS is mandatory policy and you need to read WP:VANDAL before you use that word to describe anyone else's good faith actions. I don't have a view one way or the other whether this content should be included but I do care when editors try to impose their views on others and ignore policy and due process. Dawkins' views may be irrelevant or they may be worthy of inclusion but it is not up to you to decide that by yourself. They carry enough weight for the New York Times to criticize them here. Sean.hoyland - talk 12:38, 1 August 2012 (UTC)[reply]

I have removed Dawkins citations that remained (and incidentally they were broken because of previous edits).

I'll start by noting that some Dawkins-related content has been removed already (1, 2). I don't agree with the edit summaries explaining the removals, but I do agree with the removals themselves.

In general I agree with HyperEntity's argument: Dawkins does not have a degree in philosophy, and does not appear to be recognized by relevant experts in the field. The relevance of these facts in regards to whether Dawkins opinion should be included is not a personal opinion; there are multiple policy and guideline related rationales for this. WP:V generally prefers reliable scholarly sources where available. WP:USEBYOTHERS suggests How accepted, high-quality reliable sources use a given source provides evidence, positive or negative, for its reliability and reputation. The existence of a NYTimes book review doesn't seem sufficient to establish Dawkin's opinions on the ontological argument are significant. Absent evidence of use by more scholarly sources, including the Dawkins content seems entirely WP:UNDUE. Retro (talk | contribs) 15:40, 31 July 2019 (UTC)[reply]

Forrest Baird

I don't think the comments of Forrest Baird are relevant or notable. Firstly he says that ontological arguments reverse their opposites, but doesn't refer to Correa's argument but instead to one of J.N. Findlay. Secondly he says reversal fails because God isn't logically contradictory, but that is exactly the objection of Michael Martin above. Thirdly, this appears to be simply a summary of some responses to the argument and it would be better to reference the original responses, not a summary. --Dishcmds (talk) 06:28, 2 December 2012 (UTC)[reply]

Why

" the mainstream view is that the ontological argument was first clearly stated and developed by Anselm of Canterbury.". So, we hipster now? 190.60.93.218 (talk) 14:05, 17 December 2012 (UTC)[reply]

The mention of Richard Dawkins among giants of philosophy is just shocking for those who study the subject and who are, I guess, the main readers of articles like this.

Hartshorne and Malcolm

I am working on expanding the modal logic versions of OA by adding Hartshorne and Malcolm. At some stage the piece on Malcolm will need to be combined with this. That piece seems to be mostly from the Malcolm primary source. At the moment I am using the Harris secondary source. Myrvin (talk) 12:54, 29 August 2014 (UTC)[reply]

Interestingly, Hartshorne is in the bibliography but is never referenced. Myrvin (talk) 13:05, 29 August 2014 (UTC)[reply]

Sense in Ontology?

If Ontology is defined as a science that studies the 'being', taking into account that the Father is defined in the Bible, not by a name, but from the unique quality: 'Yahweh'= 'The One Who Is', meaning 'existing by himself', no need to discuss or explode the concept, that is self-contained. The expression: 'The greatest being mind could imagine', is contradictory in itself, as no quality of the Almighty can be represented in no way by a creature, be it made of flesh or spirit, it's simply beyond the mental abilities, powers. This puts the whole argument and related field of thought in the realm or category of empty rhetoric, of intellectual auto-erotics or dating calls. Is this a line deserving study? Agur ta erdi, Salut †--Caula (talk) 08:26, 21 April 2017 (UTC)[reply]

The whole thing is obsolete, since there are lots of gaping holes in it that one can only see if one knows a bit about logic and math.

Vague definition: what is a "being"? Is Santa a being? Is the set of all beings the universal set, a well-known paradoxon (Russell's paradox)?
Another vague definition: how is "great" defined? Is Santa greater than Sauron? An undefined and therefore totally arbitrary and subjective order relation.
How many "beings" are there? Is the set infinite? In that case, it is not guaranteed there is a greatest element.
Argument from lack of imagination: if you can not imagine something, that does not mean that nobody else can. So the determination of the greatest such being is even more subjective.
Switcheroo or Sleight of hand: A word that already has a meaning ("God") gets a new definition. Then you "prove" (in a faulty way, see above) that the thing the word stands for (by the new definition) exists. Then you pretend that you have proven that the thing (in the first meaning) exists.

So, the whole thing is rickety to the point of uselessness. Don't bother to refute it. Richard Dawkins said the reasoning is so faulty one does not know where to begin to refute it, and that is right on spot.

Independently of that: this page is for discussing how to improve the article, and the article cannot contain what we think - only what reliable sources say. One more reason not to bother. --Hob Gadling (talk) 10:56, 21 April 2017 (UTC)[reply]

Perfection as a subjective concept

Is it also worth mentioning in the article that some aspects of perfection are subjective? I think it's worth including since the basis of the argument is the ability for someone to conceive of a perfect being, and thus that conception will based on subjective views of perfection. Unfortunately there seems to be no real source for the origin of this counter-argument, so its inclusion is difficult. Trainer Alex (talk) 17:41, 13 December 2018 (UTC)[reply]

typo in section about Chambers?

> He also claimed that the no devil corollary is a strong challenge, as it "underwrites" the no devil corollary, which "threatens Anselm's argument at its very foundations".[53]

This sentence doesn't make much sense to me, as it suggests that the no devil corollary underwrites itself. I am guessing it should say "'underwrites' the devil corollary" instead. I don't have a copy of the cited book to check, though.

Comments of Spinoza

More specifically, on the St Anselm's argument he wrote:

Logically it can be stated in a variety of ways: any discourse marks off a realm of discourse in such wise that any consistent statement indicates a real and intelligible nature. Or stated more rigorously: a postulate may be formulated such that from it and from the definitions involved it its statement a proposition may be deduced concerning the nature of the reality in which such a postulate is possible; the truth of that proposition would follow not from assent to the postulate but from the very existence of the postulate. For thinking to be possible, it is said in effect, there must be an infinite perfect being. But to formulate such a postulate is an act of thought; it must, according to its own statement, be referred to a perfect intelligible being who is implicated in any statement. Yet knowledge of his nature will be independent of the truth or falsity of other statements; in fact, although the being of God is first indicated in these statements, once it is knov/n such knowledge will not depend on the truth or falsify of the statements, but on the contrary their truth or falsity will depend on the nature of God. Even the primitive postulate is no longer postulated but is made apodictic by the better attested truth of God's existence.
— Baruch Spinoza, 17th century^[1]^[2]^{[citation needed]}

I don't know exactly the Wikipedia's rules for a similar case. But the citation is remarkably relevant for the WP article, it is sourced by two authoritative secondary references, but no one of them indicates the Spinoza's work from which the citation is derived. Hence, there is a template:citation needed that is related to the lacking of the primary source. A closely similar same text is used in academic contexts.Theologian81sp (talk) 22:10, 10 June 2021 (UTC)[reply]

Norman Malcolm

More weight should be given to Norman Malcolm's argument as it is considered by some experts such as Michael Lacewing to solve the dilemma around the "existence is not a predicate" side of things. — Preceding unsigned comment added by 46.60.253.173 (talk) 13:15, 30 November 2021 (UTC)[reply]

Plain false definiens?

Anselm defines God = a being than which none greater can be imagined. But can there be a being than none greater can be imagined? Assume there is such God. But we could always add the natural number 1 to God and God + 1 would be greater than God. So by Anselms very definition there cannot be God since there cannot be a being which none greater can be imagined. Is that not a much more simple & straightforward destruction of the ontological argument, but then why do I not read about it? Did no philosopher think about it or do I miss something?

There is no consensus about Anselm NOT being the originator of the ontological argument

I've never heard any Philosopher suggest that Anselm wasn't the first to form the ontological argument. This Wikipedia article makes the claim that he wasn't, and it links to the opinion of ONE person who thinks otherwise. That's not a "consensus", as this Wikipedia article claims. The source itself even says Oppy doesn't agree, so, again, there is no consensus.

That's a fringe view. 2601:840:8681:9690:0:0:0:B103 (talk) 17:10, 13 August 2022 (UTC)[reply]

Reconstruction of Plantinga missing proper source

In the section on Plantinga, there is the following reconstruction of Plantinga's argument:

A version of his argument may be formulated as follows:^[1]

A being has maximal excellence in a given possible world W if and only if it is omnipotent, omniscient and wholly good in W; and
A being has maximal greatness if it has maximal excellence in every possible world.
It is possible that there is a being that has maximal greatness. (Premise)
Therefore, possibly, it is necessarily true that an omniscient, omnipotent, and perfectly good being exists.
Therefore, (by axiom 5 of S5) it is necessarily true that an omniscient, omnipotent and perfectly good being exists.
Therefore, an omniscient, omnipotent and perfectly good being exists.

^ Oppy, Graham (15 July 2011) [8 February 1996]. Ontological Arguments. Stanford Encyclopedia of Philosophy.

I've been trying to track this reconstructiuon down and I have not been able to find it in the source cited for it. Neither the original version, the spring 2011 edition, the fall 2011 edition nor the spring 2024 include this reconstruction. If someone knows where this reconstruction is from, please provide more citation information, so it can be found. Otherwise, I think it should perhaps be deleted, even though it is correct.

Thanks for digging this up!

I've had a look at the article cited from Craig's Routledge Encyclopedia of Philosophy (the DOI is: 10.4324/9780415249126-K029-1). It was written by Plantinga but it does not contain that reconstruction. He doesn't even talk about his own argument, rather, he only refers to Hartshorne's. And what he does reconstruct of Hartshorne's argument, he reconstructs in terms of instantiations of maximal greatness (rather than maximally great beings). Technically, this isn't a huge problem, given that Plantinga himself writes in God, Freedom and Evil that his talk about maximally great beings and instantiations of maximal greatness are interchangeable (cf. Plantinga, God, Freedom and Evil, p.102). Nevertheless, that reconstruction is missing a source. Applesandoranges501 (talk) 21:29, 26 September 2024 (UTC)[reply]
