The Ontological Argument For The Existence Of God

Humans are finite substances so they cannot come up with the ideas of infinite substances unless it were given to them by an infinite substance. Descartes continues that while we advance gradually each day these attributes could never exist within us because we are only potentially perfect whereas God is actually perfect. Furthermore, Descartes argues that only God could be the author of his being because if it were he or his parent’s other finite substances that authored his being then he would not have wants or doubts because he would have bestowed upon himself every perfection imaginable to a finite being. Therefore, God exists because Descartes could not have thought of God because he is a finite substance thus the idea of God must have come from an infinite substance.

In this paper, I will deliver a reconstruction of Anselm's Ontological argument for the existence of God, and its adequacy for the existence of the greatest conceivable being. I will establish this by proving that Anselm's premises are sound and that the deductive arguments follow through a valid conclusion.

Rene Descartes’ third meditation from his book Meditations on First Philosophy, examines Descartes’ arguments for the existence of God. The purpose of this essay will be to explore Descartes’ reasoning and proofs of God’s existence. In the third meditation, Descartes states two arguments attempting to prove God’s existence, the Trademark argument and the traditional Cosmological argument. Although his arguments are strong and relatively truthful, they do no prove the existence of God.

The existence of God has always been an arguable topic. Descartes’ however, believed that he had proof of God’s existence through an intense analysis of the mind. Throughout this paper I will discuss what he has provided as proof and some of the complications that arise throughout his argument.

In this paper, I offer a reconstruction of Descartes argument for God’s existence in the Third Meditation. Descartes tries to prove the existence of God with an argument that proceeds from the clear and distinct idea of an infinite being to the existence of himself. He believes that his clear and distinct idea of an infinite being with infinite “objective reality” leads to the occurrence of the “Special Causal Principle”. I will start by discussing and analyzing Descartes clear and distinct idea of an infinite being and how it the classification of ideas and the difference between formal and objective reality Special Causal Principle. Finally, I will examine the reasons Descartes offers for his belief in Gods existence and I will indicate the drawbacks within the proof. It will be concluded that Descartes arguments are inadequate and don’t clearly prove the existence of God.

Descartes makes an attempt to prove God’s existence throughout his third meditation. In his first premise he states that he has an idea of an infinitely perfect being. He uses the Principle of Sufficient reason to advance his argument; it states that everything must have a reason or cause. This put forth his second premise; that the idea of god must have a

Anselm's ontological argument is a philosophical argument which aims to prove God's existence. The ontological argument is an argument for God’s existence based on reason alone. According to this argument, there is no need to go out looking for physical evidence of God’s existence; we can work out that he exists simply by thinking about it logically. (Anon., 2004) Anselm’s argument is a reductio argument, it seeks to demonstrate that a statement is true by showing that an absurd result would follow from its denial. I will be discussing three objections to Anselm’s argument which I will reply to, namely: ‘the perfect island’ objection by Gaunilo; ‘existence is not a predicate’

The Ontological Argument for the Existence of God The ontological argument is an a priori argument. The arguments attempt to prove God's existence from the meaning of the word God. The ontological argument was introduced by Anselm of Canterbury in his book Proslogion. Anselm's classical argument was based on two principals and the two most involved in this is St Anselm of Canterbury as previously mentioned and Rene Descartes.

The ontological argument can be stated in this way: “God is the greatest being imaginable. One of the aspects of perfection or greatness is existence. Thus, God exists.” Or put another way—“The fact that God can be conceived means that he must exist.”

In the Fifth Mediation, Descartes purports his ontological argument for the existence of God. It is simpler than his first and based on God's essence. For anything else that exists, the essence of that thing only implies it's existence. For God, however, essence

In A Discourse on the Method, Descartes attempted to prove the existence of God in a priori manner. He did not trust his own senses when trying to prove the existence of God and therefore he relied on the ontological argument. By making the same assumption made by Anselm, which was that an ontological argument assumes that existence is a predicate of God, Descartes is able to conclude that ‘God exists’ is true by definition because the subject ‘God’, who already contains all perfections, already contains the predicate – exists, which is a perfection. Although this may be perceived as a strong claim to believers, many such as Gaunilo would have disagreed. Descartes postulates his argument in the fourth part of his Discourse in order to try and prove the existence of God. One must discuss why one feels Descartes attempted to do so and exactly how convincing his claim is. However, before one can understand his claim, it is important to grasp an idea of the background that Descartes was writing from when he wrote the Discourse and the meaning of proof.

Descartes’ Meditations on First Philosophy (1641) contains six Meditations. In the first two of these Descartes addresses doubt and certainty. By the end of the second Meditation Descartes establishes the possibility of certainty by concluding that he is a “thinking thing” and that this is beyond doubt. Having established the possibility of certainty, Descartes attempts to prove the existence of God. The argument he presents in the Third Meditation for the existence of God has been nicknamed the ‘Trademark’ argument. This argument deals with types of ideas, of which there are three, a principle called the Causal Adequacy principle, and a sliding scale of reality. The argument concludes that the idea of a God that is a perfect being is an innate idea that is real and was caused by God and therefore God is real. This argument will be explained with the greater detail in the next paragraph. In the Fifth Meditation Descartes again addresses the existence of God with an argument for His existence. This argument is a variation of St. Anselm’s ontological argument. This argument is also framed around his theory of ideas, as well as his principle of ‘clear and distinct perception’ and is explained and discussed in paragraph three. The paragraphs following these will discuss how convincing these two arguments from Descartes are and will deal with various objections. Many of these objections are strong enough that it will be clear why Descartes’ case has failed to convince everyone.

The concept of God is central to the development of Cartesian and Spinozan philosophy. Although both philosophers employ an ontological argument for the existence and necessity of God the specific nature of God differs greatly with each account. While Descartes suggests a Judeo-Christian concept of God, Spinoza argues a more monistic deity similar to that of the Hindu tradition. The most significant difference however, lies within the basis and structure of each argument itself. Considered from an analytical standpoint through the lens of Gotlobb Frege, Descartes' proof of God possesses both sense and reference and is therefore capable of expressing the

I begin with the constructs of Anselm. The ontological, or a priori, argument was first expressed in 1070 by Anselm. He argued that because we have a notion of an all-perfect being "that than which nothing greater can be conceived" – It must be God. Anselm regarded God as a being one who enjoys all conceivable perfection. Yet if God "existed" only as an idea in our awareness, then God would be less perfect than if He in fact existed. Therefore God had to be greater than what our finite minds have ability to conceive so as not to contradict the definition of God.

The Ontological Argument is a deductive argument in that it endeavors to demonstrate that its premises lead to a logical conclusion which can't be doubted. For this situation, rationalists have endeavored to demonstrate that the expression 'God Exists' is an analytic proclamation in that it is logically incomprehensible for it not to be the situation, generally as it is outlandish for a lone wolf to not be an unmarried man. This sort of argument is known as 'from the earlier' on the grounds that it depends on logical reasoning. Descartes' ontological argument is both a standout amongst the most interesting and inadequately comprehended parts of his philosophy. Interest with the argument originates from the push to demonstrate God's existence
