- If it is possible that something exists, then it does exist in a possible world.
- It is possible that a maximally excellent being exists in a possible world.
- Therefore, a maximally excellent being exists in some possible world.
- A maximally great being would be a maximally excellent being that exists in all possible worlds – i.e. there is no being that has excellence superior to its.
- It is possible that a maximally great being exists – i.e. that a maximally excellent being exists such that it has maximal excellence in every possible world.
- Therefore, a maximally great being exists.
- God is, by definition, a maximally great being.
- Therefore, God exists.
Alvin Plantinga offered a modal ontological argument for the existence of God as summarized above. If God exists in all possible worlds and we inhabit a possible world, then God exists in our world. Once someone has conceded that it is possible God exists, according to the logic outlined above, they must accept that God actually does exist.
This argument is not subject to the criticism that having an idea of a maximally great being does not actually entail that such a being exists. Nor is it subject to Kant’s criticism that existence is not a predicate: God’s existence is special because it is defined as existence in all possible worlds, which makes it a different species of existence from our own. For example, while it is possible that I exist in a possible world, it is also possible that I do not exist in another possible world.
The argument hinges on the possibility of a maximally great being. This is an a priori claim. Detractors might object that such a being is not possible, therefore the argument does not succeed. But note: this criticism does not challenge the validity of the argument but its soundness. They allege that this premise is false.
The burden of proof lies with the detractors: they must give a reason for why such a being is not possible. At this point arguments are introduced that allege the divine attributes are incompatible or that God is incompatible with the possible world we inhabit. Here are a few such challenges:
- The paradox of the stone
- Kretzmann on omniscience and immutability
- Omnipotence and supreme goodness
- The Euthyphro dilemma
- Omniscience and human free will
- The evidential problem of evil
- The logical problem of evil
Theists have offered defences and theodicies in response to all of these arguments. In any case, much of this is actually a distraction: the ontological argument is not meant to show that God fits our (popular) conception of Him, but that a maximally great being exists. The coherence of maximal greatness and our complete understanding of maximal greatness are not the same issue.
We treat the concept “MULTIPLY” as coherent, but do we understand everything about it? If we accept that we lack complete knowledge of such a concept, but that this does not justify throwing the concept out, then by the same reasoning we must accept that our lack of complete knowledge regarding “MAXIMAL GREATNESS” does not entitle us to throw it out.
Moreover, transcendence is part of the concept of God. Transcendence can be understood in relation to ontology (God is beyond the universe) and also in relation to epistemology (God is beyond our ultimate comprehension). This does not amount to special pleading because transcendence is part of the definition of God: God is not coherent if God lacks transcendence, whereas transcendence is not part of the definition of, say, APPLE.
We must also consider the coherence of challenging God’s existence. Now this does not show that God actually does exist, but as Quine has pointed out, it does show that we are intellectually committed to God’s existence – He is a necessary presupposition for our reasoning. This results in a curious outcome: atheism – even if true – is unjustifiable. Most epistemologies include some kind of justification as a necessary condition for knowledge: the tripartite theory; infallibilism; virtue epistemology; reliabilism; Nozick’s “tracking the truth” reliabilism. The nature of justification is disputed, but most accept that something gives validity to our true beliefs to convert them into knowledge – some principle “guides” us into truth and that principle, even if it is built on truth, is not identical to it.
The question, “Is it possible that God exists?”, is incoherent. God is defined as a necessary being, whereas possibility speaks of contingency. Possibility itself is contingent on God, not God on possibility.

My take is slightly different, I think it does show that God exists, and that God is beyond our understanding – but it is irrelevant. I would argue that every human knows God exists.

Yes, the issue is how we characterize it: God is self-sufficient, which is why He has the glorious Name He revealed to Moses in Exodus 4: Ehyeh asher Ehyeh, “I am that I am” > Yahweh. But creatures depend on God for their existence – they are not self-sufficient, which is why He is Most Glorious. In philosophy speak, we say that God has necessary existence, but creatures have contingent existence. Exodus 4 is a very special passage for me personally and allowed me to make sense of John 1 as the glorious revelation that Jesus is Yahweh – that is what opened my heart to loving God – before that I feared and hated Him.

To come to the knowledge of all, desire the knowledge of nothing. To come to enjoy what you have not, you must go by a way in which you enjoy not.

My problem with this ontological proof comes from personal drug induced experiences in college . . . specifically my experience with DMT which makes LSD look like a pop gun compared to ab Atom bomb.
At once one is thrust into a ‘reality’ that can only be described by a declarative sentence: “Here I am again!” . . . a feeling at once of a return to a cosmic home of consciousness and a loss of any reality to anything one can claim regarding their present life of memories, acquaintences, experiences. It is like being awash in pure being which is also existent in a 3 dimensional fractal of sorts. As for possibilities, it is similar to a dream where one can concentrate on a specific speck and enter into it and make of it a reality or possible world to be explored and lived in . . . the further one goes in the further the micro bit becomes the macro and final reaches a state of becoming fully a new reality to be explored and ‘lived’. It is more a Buddhist experience of a dream state. except that there is a knowledge that none of it is real except for the “I” of the experience.
All things are possible as #1 explains and it is one of a myriad of possible realities. Though #2 speaks of excellence as a possibility I suppose that would be a possible contingent though another would be that any reality is as excellent as another and that the only unchanging part is the “I”. All the rest that follows by the numbers leads to the ultimate conclusion that there is a God and that God is “I”.
So it seems to me, and did at the time, that what the Westerner experiences under the influence of the drug DMT points not to God the Creator of the cosmos but to the truth of the Eastern religions and the idea that reality is nothing but the dream of the sleeping Buddha.
And yes, since it was only a mental aberration of a drug on the mind it can be dismissed [and I do]. Though its similarity to the undrugged beliefs of Buddhism are quite interesting though flawed. There is a certain centrality of “I” in their ‘possibility’ of what existence amounts to. And of perfection, one only needs awake to the fact that they themselves are that perfect “I” . . . nirvana . . . an awakening.
So I am with Phillip here: give me the 5 demonstrations of God by St. Thomas as it makes a far better argument for my money.

Equally, though, you could follow Berkeley: Buddhism comes from a place of scepticism and egoism, but we don’t necessarily have to think that way. If we do as a consequence of the Fall, we still need to interpret what that means – Calvinist total depravity or something lighter? Berkeley thought about how he couldn’t control his perceptual experiences, and that led him to conclude that God must be in control of them – so Berkeley isn’t God.

I understand what you are arguing, I think. Though it seems to me to be non-satisfactory at the lowest common denominator of human experience. It seems rather a scholarly meandering in a particular way of thinking . . . which is uncommon amongst the common folk. I find it of the same sort of thought that is precipitated from science regarding, especially, the fact that all that truly existss is bundles of energy (whatever that is) and it composes both the living and the non-living and exists for all eternity. Even mass within the E=mc2 is comprised of these orderly bundles of energy. It makes one ask many a question. How does a particular arrangement of these little bundles of energy think, distinguish, or wonder at its own existence? I find all these excursions of the mind interesting to meditate upon but with an underpinning of the existence of a Mysterious God far too vast to contemplate and to admire fully within the realm of rational thought processes. Try as we might to know the Knower, we fail to know the Unknown God Who is our All.
