The Ontological Argument

Extracts from this document...


The Ontological Argument a) Outline the ontological argument for the existence of God. b) How convincing does you find the argument. (GR4YA) The ontological argument is an attempt to prove God's existence a priori. It does not rely on our observations of the universe, the world around us. It uses logic, and the idea that it is illogical to say that God does not exist, as its main argument. The ontological argument was first put forward by St Anslem of Canterbury and later by the French philosopher Rene Descartes. Anselm, writing to convince believers that they were right and correct in their beliefs, declared that anyone should accept his definition of God. He defines God as, 'That than which nothing greater can be conceived'. In other words, God is the most perfect being imaginable. Note that Anselm is careful not to define God as the greatest thing in existence, as this would not necessarily be God (it would however exist by definition). ...read more.


This is, by definition, an untrue statement, therefore God must, by definition exist. Anselm strengthened his argument in response to a criticism by one of his contemporaries. The French monk Gaunilon (who was himself a believer in God) argued that Anselm's argument was ridiculous. He said that if he were to apply the same logic to other things he could prove that the most perfect 'anything' exists. The example he used was that of an island. The most perfect island must exist by definition because otherwise there could be more Perfect Island, i.e. one that exists in reality. Anslem responded to this criticism by stating that unlike an island it is only God who must have existence as part of his definition. An island is defined as land surrounded by water, it does not have to have existence as a characteristic. God, however, is a necessary being and therefore existence is part of his definition. With and argument based entirely on analytical reasoning, the definition of words and the use of language, Anselm and Descartes felt that they had produced a proof for God's existence. ...read more.


Kant uses Descartes own example of a triangle. He states that just as if there is a triangle then it must have 180 degrees, so also, if there is a God he must have the characteristic of existence. In other words, 'if God exists then he exists'. A second objection to the ontological argument was raised by David Hume. It is not possible to begin and argument based upon mere logic, which is present only in the mind and reach a conclusion which is based entirely in the observable universe. We, as human beings simply do not work this way. We base our lives and our conclusions on those things which we can observe, not those things which we can rationally prove; these things stay in our minds only and have no real impact on our real worlds. Although the ontological argument is based on some valid reasoning, it is essentially flawed and unconvincing. It assumes to know the nature of an unknowable God. It presumes that the characteristic of existence adds to the perfection of a thing. It starts with analytical logical and reaches a fallacious conclusion about the synthetic world. ...read more.

  1. "Modern visions of the Ontological Argument are more successful than early versions"

    equivalent to the claim that the concept of a maximally great being is not self-contradictory; for the only things that don't exist in any possible world are things that are conceptually defined in terms of contradictory properties. There is no logically possible world in which a square circle exists (given the relevant concepts)

  2. Explain the Ontological argument.

    This is unacceptable because one could define anything into existence. Many have dismissed Plantinga's argument attacking his concept of 'possible worlds'. Criticism focuses on his assumption that there is a being with 'maximal excellence' in every world means that such a being must exist in our world.

  1. The ontological argument

    Descarte said in Meditation V; 'From the fact that I cannot conceive of God without existence, it follows that existence is inseparable from him, and hence that he really exists.' Therefore it is concluded that a man who questions the existence of God isn't describing God because of the necessity of Gods' existence.

  2. Describe the ontological argument with reactions and contributions made to it by philosophers.

    God is such a being, he can not not exist. Two modern day suporters of theory are Norman Malcom and Alvin Plantinga. Malcom said that Gods existence was either impossible or necessary and, assuming that the concept of God is neither absurd or contradictory, God must be necessary and therefore exist.

  1. Preliminary Interpretation of Descartes Meditations

    Nonetheless Descartes brushes over this saying "But despite the fact that the senses occasionally deceive us about things that are very small or far away, perhaps there are many other things about which one surely cannot have doubts, even if they are derived from the sense" What Descartes is saying is that although the senses deceive us occasionally i.e.

  2. The French philosopher Rene Descartes

    Now these senses I have sometimes found to be deceptive; and it is only prudent never to place complete confidence in that by which we have even once been deceived. (Descartes, Rene, "Meditations," Struhl, Paula Rothenberg, and Struhl Karsten J., editors, Philosophy Now.

  1. The Ontological Argument.

    For Anselm any being that has the attribute of existence is greater than a being that did not have the attribute of existence. Therefore, that for Anselm, 'God is that than which nothing greater can be conceived' means God must exist.

  2. Explain the Ontological argument from Anslem and Gaunillo's objection 9s?

    Anselm stated, because when the Fool hears 'something-than-which-nothing-greater-can-be- thought', he understands what he hears, and what he understands is in his mind. Thus, the God is in his mind. Gaunilo opposed Anslem arguent and wrote an attack on it "A reply to the forgiving by a certain writer on behalf
