A Defense of The Classical Ontological Argument

Introduction

The ontological argument has confused many people and has intrigued many philosophers. However, most people do not find the argument convincing because of an obvious problem. This problem has come up since Anselm first gave the argument and when Christian philosophers and apologist presented it to unbelievers. The problem for the Classical Ontological argument is called the “Lost Island” Objection. Although there are many objections to the ontological argument this one seems to be the most enduring . In this paper I will offer a solution to the lost Island objection and defend the general reasonableness of the Classical Ontological argument thereby providing a contribution to justified theistic belief. First, we will take a look at the ontological argument followed by a brief explanation and a defense for the argument. After this we will look at the “Lost Island” objection and my solution to it. Finally, I will make some concluding remarks.

The Argument Stated

This is how Plantinga states the argument in a way that is clear and that does justice to the primary text of the Proslogion . I have added some extra premises to make the argument even clearer. The Argument is as follows:

1. God is the being that than which nothing greater can be conceived (def. of God or it can be stated like this: I can conceive of a being that than which nothing greater can be conceived and this is what we call God)
2. God exists in the understanding but not in reality. (Assumption for reductio)
3. Existence in reality is greater than existence in the understanding alone. (Premise)
4. A being having all of God's properties plus existence in reality can be conceived. (Premise)
5. A being having all of God's properties plus existence in reality is greater than God. (From (2) and (3).)
6. A being greater than God can be conceived. (From (4) and (5).)
7. It is false that a being greater than God can be conceived. (From definition of "God".) 8. It is false that God exists in the understanding but not in reality. (From (2), (6), (7).)
9. God exists in the understanding. (Premise that the fool grants for reductio.)
10. Therefore, God exists in reality. (From (8), (9).)

Now that the basic structure of the argument is laid out we can look at explaining the premises and try to defend the ones that seem less plausible.


Explanation and Defense

The purpose of this section is to provide an explanation of each of the premises and to give a brief justification and defense of some of the more contentious premises.
Premise 1

Premise one can be stated in two ways as I have parenthetically noted; this is important because some might think that one way is reasonable and the other is not. For myself it is intuitively reasonable to think that God is a being such that nothing greater can be conceived. However, if one thinks that this definition of God begs the question and is put forth for the sole purpose of being able to just arbitrarily prove God by an inference from a manipulation of words then perhaps this route ought to be avoided. An alternative route that ought to be taken by the defender of the classical ontological argument is to suggest that one should just contemplate a being that than which nothing greater can be thought. If one uses the latter way of stating the premise then this does not commit anybody to any preconceived definition of God that would be considered by some to be controversial. Therefore, either way is sufficient for the rest of argument to follow reasonably.

Premise 2

This premise is assuming that one can have a mental conception of a being that than which nothing greater can be conceived. I would take Anselm’s use of the term “in the mind” or as I put in the premises “in the understanding” as being able to intellectually grasp either an attribute(s) or substance . Anselm believes that we can grasp God in some sense because he believes that God is a substance . Furthermore, one might be able to have such a concept of a being that than which nothing greater can be thought before our minds eye by taking the lesser goods that we see in the created order or before our minds and abstracting from those lesser goods to greater goods all the way to a being that than which nothing greater can be thought . However, it should be stressed that this sort of mental abstraction is not necessary to have a robust concept of a being that than which nothing greater can be thought. For myself I know that I can have such a concept before my minds eye pretty immediately and from that concept I can infer many great making properties. Thus, all one would need to grant in order for this premises to be accepted is that one can have an idea of God in the mind or in understanding. This premise is stated in such a way as to be shown in latter premises to be reduced to absurdity so that from the negation of this absurdity one can infer God’s existence.

Premise 3

The third premise of the classical ontological argument is by far the most controversial part of the entire argument because once someone accepts the third premise and the assumptions imbedded therein then the rest of the argument seems to follow inescapably. Therefore, I will deal with this premise in two parts; the first part I will examine the philosophical assumptions in this premise and the second part I will give a justification of these assumptions.

The two main assumptions that go into this premise is that there are things that are or can be objectively great and that existence is one of these things that is objectively great. What I mean by objective is that something is what it is apart from human wants, desires, and beliefs . In other words, it is not grounded in human opinion or apprehension. The assumption here is that great things exist and that they can be compared to a being that than which nothing greater can be thought. However, it might be charged that if this is true then there are things in creation that we can compare objectively to other things in creation . An example of this would be saying that a deer is objectively better than a bear and so on . Yet this example does not make any sense because it seems that a deer is not necessarily something you can compare to a bear to see which one is objectively better . Anselmian philosophical theologians are not necessarily committed to this claim as Thomas V. Morris puts it “….The characterization of God as the greatest possible being does not require universal value-commensurability. It does require that every object be value commensurable with God, but not that every object be so commensurable with every other object”. Morris is suggesting here that other things need not be comparable to one another, but the only thing that we can compare everything to is the greatest possible being, which is God . Another assumption is that existence is one of these things that are great, that is to say being is better than non-being. In the next paragraph we will give a rational justification of this assumption, namely that existence is better to have rather than not.

The rational warrant or justification for the assumption that existence is objectively great is intuition. Intuition is analogous to perception, but the difference is that it is done with mental conception, that is to say the mind’s eye. Intuition is used to justify moral, mathematical, and analytic truths . We use our mind’s eye to just see that 1+1=2. By the nature of what it is to be one and one we can just see that it has to equal two. We just see with our mental conception that the nature of goodness is as such that it would be incompatible with evilness. People have disagreed in the past over what is intuitive and what is not. This suggests that one can be mistaken about the intuition, but that does not mean that just because we can possibly be mistaken about a proposition that therefore we do not know it or be rationally warranted in believing it. We can be mistaken about things in our perceptual experience, but that does not mean that everything I perceive does not count as knowledge. For example, my best friend could be a Humanoid Robot (like in the Terminator movies) to deceive me, but there is no reason to believe such an outrageous proposition, but yet this is still possibly true. However, we would still say that I know my friend is not a Robot even though I can be possibly mistaken about that. This is a falliblistic account of knowledge as opposed to infallibilistic account of knowledge. With that understanding in hand, it seems intuitive than not to us that it is better to exist in reality rather than in the imagination alone. This is especially intuitive when we are thinking of the way in which a being that than which nothing greater can be thought exists in reality. Finally, this existence gives actuality to the greatest imaginable being so existence in this sense is inescapably better to have rather than not.

Premises 4-10

The most contentious premises have been defended and explained. Thus, I will just briefly discuss the rest of the premises for the sake of clarity. Premise 4 is the first premise which begins to flush out the argument for the assumption of the reductio in premise 2. It is arguing that the fool can conceive of a being just like God but that this being actually exists. But as premise 5 points out if this is true then this being would actually be better than God given the assumption in premises 1 that God is that than which nothing greater can be thought. Then the argument at this juncture is designed to show a contradiction from the obvious tension between premises 6 and 7. From this contradiction between 6 and 7, premise 8 infers the opposite in order to avoid God existing in the mind but not in reality. The opposite would be that it is false that God exists in the mind and not in reality. Thus, premise 9 and 10 do the work of drawing out the opposite conclusion: that God exists in the mind and in reality. This thereby shows that it is reasonable to believe that God exists.

A Popular Objection to the Classical Ontological Argument

One of the most popular and apparently decisive objections to the classical ontological argument was by a monk named Gaunilon. Gaunilon tried to offer a counter example to defeat the intuition that it is better to exist in reality rather than just in the imagination alone. This is called the lost Island argument and it is so apparently devastating that it ought to be quoted:

“…it is said that somewhere in the ocean is an island, which, because of the difficulty or rather the impossibility, of discovering what does not exist, is called the lost Island. And they say that this Island has an inestimable wealth of all manner of riches and delicacies in greater abundance than is told of the Islands of the Blest….Now if some one should tell me that there is such an Island, I should easily understand his words…..suppose that he went on to say, as if by a logical inference: “you can no longer doubt that this island which is more excellent than all lands exists somewhere, since you have no doubt that it is in your understanding. And since it is more excellent not to be in the understanding alone, but to exist both in the understanding and in reality, for this reason it must exist. For if it does not exist, any land which really exists will be more excellent than it; and so the island already understood by you to be more excellent will not be more excellent ”

Gaunilon was trying to reduce Saint Anselm’s intuition that it is better to exist rather than not to absurdity. If Anselm’s formula was correct then we could define anything into existence that is greatest in its class. We could show that an Island that than which no greater Island can be thought does exist and also a unicorn that than which nothing greater can be thought. If a unicorn that than which nothing greater can be thought did not in fact exist then we could think of a greater unicorn, namely, one that exists. This would result in a contradiction or absurdity if these premises are granted and thus the greatest possible unicorn would be inferred to exist from this negation. In fact anything with the formula in front of it that says “that than which nothing greater can be thought” could be proved to exist as such. But since we know more reasonably that this is false than the intuition that it is better to exists rather than not then we have a sufficient defeater or decisive reason to doubt that it is better to exist rather than not. Therefore, Gaunilon and many people who doubt this argument are warranted in their doubt unless the defender of the classical ontological argument provides a defeater-defeater.

A Response to the Popular Objection to the Classical Ontological Argument

The response to this classic objection is going to be answered by Anselmian perfect being theology and philosophy to which I plan to define and illustrate. Then I am going to argue from the concept of a being that than which nothing greater can be thought to the conclusion that only a concept such as this can be the only concept that can be just seen to exist. Then I plan to put forth potential objections to my solution and the response to those objections.
Anselmian Perfect Being Theology and Philosophy

Anselmian perfect being theology and philosophy takes the concept of God as being that than which nothing greater can be thought or God as the greatest conceivable being and from this concept of God one can infer certain great making properties . A great making property is a property that is better to have rather than not . God will have every great making property since this is entailed by the concept or definition of him being that than which nothing greater can be thought. For if God lacked any great making property we could conceive of a greater being with all those great making properties that God has plus that great making property that God would lacked. But then this would be a contradiction since you could think of a being greater than the greatest thinkable being. In addition, these great making properties are also justified by intuition like the justification for existence being a great making property. An example of a great making property would be omniscience. For example, let us suppose we are engaging in the project of perfect being theology we would ask the question: Is it better for God to be omniscient or not? Well it is reasonable to think that all knowledge is intrinsically and objective better than having no knowledge, therefore from Anselmian perfect being theology (which includes Anselm’s concept of God) one would infer that God is omniscient. Other examples of great making properties would be necessity, omnipresence, moral perfection, and omnipotence. Moreover, there are other great making properties that are more controversial among theologians and philosophers like divine simplicity, impassability, and timelessness . Therefore, since some great making properties are uncontroversial and others controversial then we can conclude that there will be some properties that are more reasonable to hold to than others. With this view of Anselmian perfect being theology and philosophy we are now equipped to look at answering Gaunilons objection to the classical ontological argument.

A Solution from Anselmian Perfect being Theology and Philosophy

Gaunilons defeater for the ontological argument is insufficient because one can infer from Anselmian perfect being theology that only God can be intuitively seen to exist by the very concept of God. We can infer from the concept of God being that than which nothing greater can be thought that he is the only being that can be intuitively seen to exist because this itself is a great making property. In other words, a great making property of God is that he is the only being that can be seen to exist by just His concept. If God is the only being that can be seen to exist by thinking of the concept of God then we are philosophically committed to the claim that this is better to have rather than not. More importantly this would mean that only God would share this great making property and that nothing else other than God would have it. Thus, this suggests that the objector to the classical ontological argument is no longer in a position to offer a defeater that would suggest that if the ontological argument is valid and sound that one could look at the concept of the greatest conceivable tree, house, bug, and Island and just infer from their concepts that they exist.

Potential Problems with the Solution

However, it must be admitted that this defeater is successfully defeated if one shows that the concept of God is such that it is the only concept by which we can infer existence is itself a great making property and this may seem questionable to some. Since my idea has not been touched in the primary and secondary literature I have no official academic citations for the possible critiques that I am about to level against my own solution . One possible critique is that this solution is arbitrary and ad hoc. In other words the concern with my solution is that it is baselessly and artificially designed to avoid the force of Gaunilo’s apparently decisive defeater of the classical ontological argument. Another possible critique is that it is unclear whether or not that being the only being that can be seen to exist by an inference from His concept is in fact a great making property. Thus, there needs to be a clear and careful answer to these objections to my solution.

A Response to the Critiques of the Solution

The reason why being the only being that can be seen to exist by its concept is a great making property is because it makes God unique ontologically and epistemologically from all other things that exist. This would be yet another property that would make God entirely distinct from the created order because no other created thing or possibly created thing can be seen to exist by its mere concept. This would make God have a uniqueness of kind rather than a uniqueness of degree . Thus, this would give further support for the creator-creature distinction which is also a great making property. Some might argue that uniqueness is in-itself not necessarily good because we can conceive of things that are unique in a negative or evil sense. However, this overlooks the fact that the concept of God is intrinsically good and any uniqueness of his substance will always be a good thing rather than neutral or evil. Furthermore, this property is great making because it makes the grounds or reasons for belief in God distinct from any other fact in the world. In other words, it gives God his epistemological uniqueness. Furthermore, this would make God’s existence something that we can just see from His concept rather than treating God like he is something of the creation that needs to be checked out and investigated in order to be believed reasonably. Thus, because of these considerations it seems like this property is a great making property rather than an arbitrary and sneaky way out of an ancient objection.

Concluding Remarks

In conclusion, we have seen that the ontological argument is valid and sound and given my brief analysis it seems to support the proposition that God exists. We have looked at the general outline of the argument and the reasonableness of each of the premises. Moreover, this paper has also shown that one of the oldest objections against the classical ontological argument fails to apply the idea of a being that than which nothing greater can be thought consistently and as a result it tries to exploit an absurd inference from soundness and validness of the argument, namely that we could just define anything that is the greatest into existence. This opens up optimism for further philosophical theology and especially philosophical theology in Anselmian tradition. This is not a truth of merger significance and the reason why it is great significance will have to be argued in another paper, but for now I will leave us with an encouraging quote about the prospects of philosophical theology in the Anselmian tradition by Thomas Morris “I believe this is correct, that there exists at least a strong prima facie case for the coherence of the elements of classical theism, and so for the coherence of an a priori conception of deity understood as entailing these elements. If this is right, then there can be a strong prima facie case for the God of Abraham, Isaac, and Jacob, if indeed he is God, being the God of Anselm, a maximally perfect being”.

  1. Wait, wait, wait. I admit; I read and then skimmed. I've been smoking. Nevertheless, I thought I say you say the following: That Gaunilo's (not 'Gaunilon's) objection was the best objection against Anselm, and that it had been refuted.

    On the contrary; in philosophical circles today, it is recognized that Gaunilo's objection was not decisive. In fact it failed, because it did not recognize the difference between categories that admit of intrinsic maximums and those that do not. "Most Goodness"; "most knowledge--i.e., belief and justification in all true propositions and belief in no false ones--; most power--ability to do anything that isn't logically contradictory, etc. These are categories that admit of intrinsic maximums; there are caps on these properties, in the very nature of what they are.

    When it comes to the properties of the perfect island--most fruit, most hot chicks with bikinis, etc--these categories do not admit of intrinsic maximums. One can always add one more hot, barely-clad girl. Thus the difference between these two categories.

    So what is why Gaunilo's objection does not work. The objection that is considered the most difficult, and haunts the argument to this day, is Kant's objection that existence is not a property. Modern modal versions were constructed for the purpose of avoiding this objection.

    Deal with the real problems, OK? ;-) Otherwise I'll just sit around and respond to Pascal's Wager and declare to have disproved theism. ;-)

  2. Wait, wait, wait. I admit; I read and then skimmed. I've been smoking. Nevertheless, I thought I say you say the following: That Gaunilo's (not 'Gaunilon's) objection was the best objection against Anselm, and that it had been refuted.

    Response: This context ought to make for clear, coherent, and good discussion.

    On the contrary; in philosophical circles today, it is recognized that Gaunilo's objection was not decisive. In fact it failed, because it did not recognize the difference between categories that admit of intrinsic maximums and those that do not. "Most Goodness"; "most knowledge--i.e., belief and justification in all true propositions and belief in no false ones--; most power--ability to do anything that isn't logically contradictory, etc. These are categories that admit of intrinsic maximums; there are caps on these properties, in the very nature of what they are.

    Response: I understand that, but I tend to disagree. In my experience the most two popular objections are lost Island objection and the kantian objection. I will deal with how the lost island objection is still a threat and how Kant's is pretty harmless.

    When it comes to the properties of the perfect island--most fruit, most hot chicks with bikinis, etc--these categories do not admit of intrinsic maximums. One can always add one more hot, barely-clad girl. Thus the difference between these two categories.

    Response: This is hardly a way to avoid the lost island objection. One could just say a Island possess a infinite amount of all the things that are better to have rather than not, so why think that there even needs to be caps? It is certainly possible that it be a Island with actual set of a infinite amount of great things that are better to have than not. But a much easier way is taking this line: one can say that it is clear that the greatest possible Island exist but it is unclear on the basis of intuition which things will be on Island and which things will be not and also the quantity of such and such. But at least we know two things about such a Island it exists and it is really great.

    So what is why Gaunilo's objection does not work. The objection that is considered the most difficult, and haunts the argument to this day, is Kant's objection that existence is not a property. Modern modal versions were constructed for the purpose of avoiding this objection.

    Response: There is a descriptive difference between a horse in the imagination and a horse that is existing independent of the imagination. And if there is a descriptive difference between these two concepts then there is a difference in properties. So I do not really see kant's argument as a threat really.

    Deal with the real problems, OK? ;-) Otherwise I'll just sit around and respond to Pascal's Wager and declare to have disproved theism. ;-)

    Response: I do, but perhaps we merely disagree what the real problems are.

  3. Hey Nate, how are ya man?

    Yeah, nice paper, creative argumentation.

    Reading it, I do not wish to object to any of the particular premises or conclusions, however, the general direction of the ontological argument still rubs on my presuppositional instincts.

    The argument, though perhaps logically sound, seems to flow through a process of "conjuring up" God. Even if Gaunilon's objection is avoided, human intuition may so strongly resist the argument's acceptence precicely because God would be THE first and only instance of anything whose concept entailed its actual existence. The heaping inductive sum of our total expericence has so painstakingly taught us that our conceptual constructions and arrangements do not lead us to actual states of affairs that even if "existence" is added as capstone to a conglomerate of conceptually assembled great-making properties, though there may be a force of intuition pushing for assent to the actual existence of this concieved great being, I feel it may be often overridden by the force of inductive custom which militates against the notion that a conceptual construction may suddenly pass from intellect into reality.

    I know that we as (presuppositional) theists hold that God has all along reavealed Himself to the non-theist, and has given him/her concept of Himself, and perhaps one may think of the Ontological argument, and its fleshing out in enumerating great-making properties as bringing a person step by step to realize thier posession of the concept of God, but the language and flow of the argument still has the feel of "conjuring up" something into being which from the outset pits intuition forcibly against it.

    Just a thought.

  4. Thanks for pointing this out. Can you send me the hard copy through a Word Doc? I promise not to disseminate it as my own. You can send it as a Read-only file for ensure it too. (Don't you love new technologies? From type writers to secured files. It's a dream.)

  5. The argument, though perhaps logically sound, seems to flow through a process of "conjuring up" God.

    Response: I disagree. If you read my paper carefully you would see that I pointed out that all one ought to have before his minds eye is the greatest possible being. So there is no definitional conjuring up.

    Even if Gaunilon's objection is avoided, human intuition may so strongly resist the argument's acceptence precicely because God would be THE first and only instance of anything whose concept entailed its actual existence.

    Response: This statement begs the question because God is the greatest possible being entails that he is the only being that would have such properties as being the only being that could be proven to exist by his mere concept. This is reasonable when one begins to obvious realize that there is only one greatest possible being given the property of uniqueness.

    The heaping inductive sum of our total expericence has so painstakingly taught us that our conceptual constructions and arrangements do not lead us to actual states of affairs that even if "existence" is added as capstone to a conglomerate of conceptually assembled great-making properties, though there may be a force of intuition pushing for assent to the actual existence of this concieved great being, I feel it may be often overridden by the force of inductive custom which militates against the notion that a conceptual construction may suddenly pass from intellect into reality.

    Response: I would say your statement has been proven false over and over again. We can conceptualize from the nature of oneness, the nature of plusness, to the nature of another oneness that is has to equal two. We conceptualize that the nature of a bachelor is a unmarried male. All these conceptualizes are true of reality and so we are shown by experience (by your broad definition of it ) over and over again that our minds are capable to build bridges to the real world.

    I know that we as (presuppositional) theists hold that God has all along reavealed Himself to the non-theist, and has given him/her concept of Himself, and perhaps one may think of the Ontological argument, and its fleshing out in enumerating great-making properties as bringing a person step by step to realize thier posession of the concept of God, but the language and flow of the argument still has the feel of "conjuring up" something into being which from the outset pits intuition forcibly against it.

    Response: I have responded this objection above in this response, in the paper and in person.
