These are mostly toy examples.

The ontological argument as proposed by

Descartes wrote in the Fifth Meditation[10] But if the mere fact that I can produce from my thought the idea of something that entails everything which I clearly and distinctly perceive to belong to that thing really does belong to it, is not this a possible basis for another argument to prove the existence of God?

Certainly, the idea of God, or a supremely perfect being, is one that I find within me just as surely as the idea of any shape or number. And my understanding that it belongs to his nature that he always exists is no less clear and distinct than is the case when I prove of any shape or number that some property belongs to its nature AT 7: The intuition above can be formally described as follows: Whatever I clearly and distinctly perceive to be contained in the idea of something is true of that thing.

I clearly and distinctly perceive that necessary existence is contained in the idea of God. In another, less formal, statement of his argument he draws an analogy between belief in the existence of God and the geometric demonstration: Whatever method of proof I use, I am The ontological argument as proposed by brought back to the fact that it is only what I clearly and distinctly perceive that completely convinces me.

Some of the things I clearly and distinctly perceive are obvious to everyone, while others are discovered only by those who look more closely and investigate more carefully; but once they have been discovered, the latter are judged to be just as certain as the former.

In the case of a right-angled triangle, for example, the fact that the square on the hypotenuse is equal to the square on the other two sides is not so readily apparent as the fact that the hypotenuse subtends the largest angle; but once one has seen it, one believes it just as strongly.

But as regards to God, if I were not overwhelmed by philosophical prejudices, and if the images of things perceived by the senses did not besiege my thought on every side, I would certainly acknowledge him sooner and more easily than anything else.

For what is more manifest than the fact that the supreme being exists, or that God, to whose essence alone existence belongs, exists? The perfection of God logically requires existence, Descartes says, in the way a mountain logically implies a valley.

And while the logical relationship between a mountain and a valley or a triangle and the sum of its sides does not imply real existence of those things, on the other hand: 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.

In his view existence is secondary to essence or quiddity, because a human can think about something and it need not exist. Everything that exists only comes into existence because it is brought from potential to actual existence by something else, except God, who is the only Necessary Existent.

He argued that in an eternal universe anything that could exist would and indeed must exist, and existence of a thing is not just a property added to it.

What first affects us are things that exist and we form ideas of essences afterwards, so existence precedes essence. This position is referred to as "primacy of existence" Template: Nothing is demonstrable, unless the contrary implies a contradiction. Nothing, that is distinctly conceivable, implies a contradiction.

Whatever we conceive as existent, we can also conceive as non-existent. There is no being, therefore, whose non-existence implies a contradiction.

Consequently there is no being, whose existence is demonstrable.

Though this criticism is directed against a cosmological argument similar to that defended by Samuel Clarke in his first Boyle Lecturesthe point applies to ontological arguments as well.

As a matter of fact, it is likely that no such island actually exists. However, his argument would then say that we are not thinking of the greatest conceivable island, because the greatest conceivable island would exist, as well as having all those other desirable properties.

Since we can conceive of this greatest or most perfect conceivable island, it must exist. Such objections are known as "Overload Objections"; they do not claim to show where or how the ontological argument goes wrong; they simply argue that, if it is sound, so are many other arguments of the same logical form that we do not want to accept, arguments that would overload the world with an indefinitely large number of necessarily-existing perfect islands, perfect lizards, perfect pencils and the like.

Glenn who himself disagreed with the proof on other grounds in his An Introduction to Philosophy. Therefore, the island analogy is not appropriate, as it has only limited application islands. The supreme being is not merely a platonic form, but a unique God who necessarily exists because his greatness is limitless.

Islands are by definition limited; they need not have every greatness. God, to be God, must have. And so this proof could only apply to the greatest being possible. Necessary nonexistence Another rationale is attributed to Melbourne philosopher Douglas Gasking —[22] one component of his proof of the nonexistence of God: The creation of the world is the most marvelous achievement imaginable.

The merit of an achievement is the product of a its intrinsic quality, and b the ability of its creator. The greater the disability or handicap of the creator, the more impressive the achievement.

The most formidable handicap for a creator would be non-existence.Since the ontological argument ultimately reduces to an axiom, the source of an objection according to Descartes' diagnosis is the failure of the objector to perceive this axiom clearly and distinctly.

Explain the Ontological Argument as Proposed by Anselm Anselm’s Ontological Argument has for many hundreds of years been fiercely criticised and defended by a great number of religious and non-religious figures.

Anselm forms his argument on reason and not evidence, making it an ‘a priori’ argument. An ontological argument for the existence of God attempts the method of a priori proof, which uses intuition and reason alone. In the context of the Abrahamic religions, ontological arguments were first proposed by the Medieval philosophers Avicenna (in The Book of Healing) and Anselm of.

Originally Answered: What is an ontological argument? Ontology is a branch of philosophy (a subfield of metaphysics) that deals with the nature of being. The ontological argument for the existence of God, at the most basic level, tries to infer the existence of God from the very nature of God.

Philosophical Issues: Parody Arguments. No sooner had the ontological argument been proposed than a refutation was developed - in the form of a joke! A "parody argument" is a comedic version of a serious argument designed to show up the flaws in . The first, and best-known, ontological argument was proposed by St.

Anselm of Canterbury in the 11th. century C.E. In his Proslogion, St. Anselm claims to derive the existence of God from the concept of a being than which no greater can be conceived.
