The Ontological Argument

The ontological argument claims that God’s existence can be demonstrated simply through reasoning. Ontology is the branch of philosophy that explores the whole concept of existence. It is an a priori argument, in that it works from first principles, pure conceptual truth and definition in an attempt to demonstrate the existence of God. It is also deductive, using logic rather than empirical evidence.

According to the ontological argument, everything (with the exception of God) exists in a contingent way; it depends upon other factors. Human beings are contingent beings because they would not exist if their parents didn’t exist before them – absolutely everything else exists contingently too. However, God is not a ‘thing’; He has not come about because of anything; there was no time when God didn’t exist. Some, such as Paul Tillich, argue ‘exists’ isn’t the right word to use of God at all.

Anselm and the ontological argument

Anselm starts by defining God as ‘that than which nothing greater can be thought’. God is understood to be the highest sum of all perfections, where absolutely nothing could ever surpass God in any way. He argued that of we have an idea of a God who is perfect in every way, where nothing could possibly be greater, then this God must exist in reality. This is because a God who just exists in our heads – something we imagined to be great but doesn’t actually exist – would be inferior to a real God, and because God cannot be inferior to anything, He must exist.

Analogies can be used to understand this point: what would be greater: a huge heap of cash that exists in your imagination, or the same heap of cash in real life? In Anselm’s understanding of God, no one could seriously argue that a non-existent God would surpass an existent God in greatness.

So, his first form of the ontological argument follows this line of argument:

God is that than which nothing greater can be thought.

A real, existent being would be greater than an imaginary, illusionary being.

Therefore, the concept of God is surpassed by an actual, existent God.

In the second form of his argument, very similar to the first, he argued that it was impossible for God not to exist, because contingent beings are inferior to beings with a necessary existence:

God is that than which nothing greater can be thought.

Because God is unsurpassable in every way. God must have necessary existence.

Therefore God exists – necessarily.

God must exist because a necessary being cannot fail to exist. According to Anselm, necessary existence is part of the definition of God – you cannot talk about a God who does not exist, because He would not be God.

Analytic and synthetic propositions

The ontological argument can be understood by drawing a distinction between two kinds of propositions.

An analytic proposition is true by definition, e.g. ‘bachelors are unmarried men’. This proposition doesn’t need to be tested, because it can be arrived at by deduction – the concept of being a bachelor involves the concept of being unmarried, and a man. Anselm, in his ontological argument, claims that the statement ‘God exists’ is analytic – the concept of God involves the concept of existence, and without existence, the concept of God wouldn’t exist.

A synthetic proposition adds something to our understanding, beyond the definition – we need more than deduction to know if it is true or not: experience. ‘The corner shop sells newspapers’ is a synthetic proposition, because the concept of corner shops doesn’t include the concept of selling newspapers – you would have to go and check to know the truth of the proposition.

Anselm argued that ‘God exists’ is an analytic a priori statement, making reference to Psalm 53:1: “The fool says in his heart, “There is no God” They are corrupt and their ways are vile.” He found it difficult to understand how anyone could have the concept of God as ‘that than which nothing greater can be thought’ without also realising that God must exist.

Gaunilo’s Criticisms of Anselm

Gaunilo was a Christian, but he thought Anselm’s argument was not logical. He claimed that these logical flaws would be made obvious if we replaced the idea of God in his argument with an island. We could imagine the most excellent Lost Island, and then, using Anselm’s logic, go on to say that for such an island to exist in our minds means that this is inferior to the same island existing in reality. It is truly the most excellent, it cannot have the inferiority that comes from it being a concept only, it must exist in reality. But clearly, there is no such island in reality, we cannot bring something into reality just by defining it as a superlative.

Anselm replied to this argument by saying that although Gaunilo was right in the case of an island, the same objection did not work when the ontological argument was used of God, because an island has a contingent existence whereas God has a necessary existence. The argument only works with God because of the uniqueness of God and how He exists.

Aquinas’s criticisms of Anselm

Thomas Aquinas argued that the existence of God could be demonstrated through a posteriori arguments, but not through a priori reasoning alone. One of his points was that God’s existence cannot be self-evident. He said that if we take a statement such as ‘Truth does not exist’, it in nonsensical because no one can accept the truth of ‘truth does not exist’ unless truth actually does exist. It is impossible to have a mental concept of the non-existence of truth because it is a contradiction in terms. However, it is not impossible to have a mental concept of the non-existence of God, because people quite clearly imagine it. If we can imagine a state of godlessness, then it cannot be a contradiction in terms, despite Anselm’s claims.

Aquinas also acknowledged that God will always remain unknowable to the finite human mind, questioning whether everyone would accept Anselm’s definition of God as ‘that than which nothing greater can be thought’. Aquinas argued that we do not all share an understanding of what God is, and rejects the premise of Anselm’s argument. He was aware of the limitations of the human mind to comprehend the nature of God and emphasised that, at least until after death, we have to accept that God is mysterious and beyond human comprehension.

Descartes’s view of the ontological argument

Descartes believed that there are some concepts that are innate and universally shared by all of humanity, such as equality, cause, shape and number, as well as an understanding of what God is. We understand God to be the supremely perfect being, with every perfection as his attributes, ‘perfection’ meaning the traditional attributes of God such as omniscience, omnipotence and omnibenevolence.

He used the analogies of a mountain and of a triangle to explain. He claimed that existence is part of the essence of God, just as three angles adding up to 180 degrees are part of the essence of a triangle, and a valley is part of the essence of a mountain. He recognised that these analogies have their limitations, as although we may not be able to think of a mountain without a valley, the mountain-and-valley combination in our imaginations doesn’t necessarily exist in real life. However, for God it is different because his nature involves perfections rather than angles or valleys, and for Descartes, existence is a perfection.

Because God has all the perfections, and existence is a perfection, God therefore exists. And because God is perfect, he must be unchanging, so he must always have existed and will always continue to exist for eternity.

Kant’s critique of ontological arguments

Kant’s major criticism of Descartes’s argument was ‘existence is not a predicate’ – in other words, existence is not a characteristic or attribute of something. Predicates describe what that thing is like – tall, green, round etc, but ‘existence’, Kant argued, is not the same as a predicate as it doesn’t tell us anything about the object that would help us to identify it in any way. When we say something ‘exists’, we are not saying that it has a certain characteristic, but rather that this concept, with all its characteristics has been ‘actualised’ or ‘exemplified’. His point is that when we are thinking of God, whether through Descartes or Anselm’s arguments, we are thinking of a concept, and whether that concept is actualised in the real world is an issue that cannot be resolved by simply adding ‘existence’ to the different predicates. We can predicate of a triangle that it has three sides, and that its angles add up to 180 degrees, but we would have to investigate further to find out whether the triangle we are picturing in our minds has been actualised.

He used the example of a hundred Prussian dollars to illustrate how existence is not a predicate. Adding ‘exists’ to the idea of God, as a predicate, doesn’t add anything new to what we understand by God, but is just a comment on whether he exists. In the same way, an imaginary $100 is not ‘added to’ if we substitute it for a real $100 – we are talking about the same amount of money either way.

Some, such as Norman Malcolm may argue against this by saying that existence is usually not a characteristic that helps us distinguish between one thing and another and so usually is not a predicate, but necessary existence is a characteristic that does draw a distinction between God and everything else, just like God’s other characteristics of omnipotence, omnibenevolence and omniscience. However, this makes the argument circular: we have to accept that God exists necessarily to come to the conclusion that God exists necessarily.

Bertrand Russell on the ontological argument

He criticised it by asking us to consider the statement ‘the present King of France is bald’. This statement is not true, but that doesn’t mean that therefore the statement ‘the present King of France is not bald’ is true, because there is no present King of France. Our use of words and the way we apply predicates, such as bald and not bald, is not enough to demonstrate that something exists, and when we apply predicates to something whose existence is a matter of uncertainty, we cannot expect the normal rules of linguistic logic to apply.

Discussion points

A priori arguments can be persuasive as they lead us to a certain truth, whilst a posteriori arguments can only lead to probabilities.

He ontological argument can seem like an intellectual puzzle made for elite, educated people meaning it is quite inaccessible. People often want to see evidence for themselves using their own senses, rather than rely on the conceptual reasoning of philosophers.

The ontological argument is not convincing enough to make someone who doesn’t believe in God change their mind, BUT Anselm did not set out to convert non-believers, he was simply helping those who already held a belief to gain a deeper understanding of His uniqueness and greatness. Religious belief is much more than just an intellectual acceptance of certain assertions, but involves, emotions, intuitions and commitment. It does not fall simply on the strength of a logical argument.

Faith in God seems to demand an element of uncertainty, and a willingness to take risks. God may need to remain partially hidden from the world to maintain epistemic distance, meaning the world should remain ‘religiously ambiguous’ so people have a choice. Only with this epistemic distance is it possible for humans to have a genuinely free will to exercise faith – if God’s existence were undeniable, faith would mean nothing.
