Thomas Aquina's vs. Descarates Essays

Descartes’s mission in the meditations was to doubt everything and that what remained from his doubting could be considered the truth. This lead Descartes to argue for the existence of God. For the purpose of this paper, I will first discuss Descartes’s argument for the existence of God. I will then take issue with Descartes’s argument first with his view on formal reality and varying levels of reality, then with his argument that only God can cause the idea of God. I will then conclude with

Both of these proofs of God’s existence are not convincing since they are founded on arguments that can be challenged. The method used by Descartes to

Aquinas argued the existence of God with five main points. Aquinas began by saying that nothing can be a cause of itself; rather every event was caused by some prior event. Therefore event A causes event B that leads to event C and so forth. He believed in this cause and effect relationship but believed that there must be a first cause as a starting point. When contemplating this starting point Aquinas rejected the possibility of an infinite series of events. This means that the universe has not existed forever and there must have been something from which every single event stems. There must be an uncaused first cause, which Aquinas concluded to be God. The first cause is called the unmoved mover. The unmoved mover is what set all other events and beings in motion.

     Aquinas’ third way argument states that there has to be something that must exist, which is most likely God. He starts his argument by saying not everything must exist, because things are born and die every single day. By stating this we can jump to the conclusion that if everything need not exist then there would have been a time where there was nothing. But, he goes on, if there was a time when there was nothing, then nothing would exist even today, because something cannot come from nothing. However, our observations tell us that something does exist, therefore there is something that must exist, and Aquinas says that something is God.

In Rene Descartes Meditations on First Philosophy, Descartes is seeking to find a system of stable, lasting and certain knowledge, which he can ultimately regard as the Truth. In his methodical quest to carry out his task, Descartes eventually arrives at the proverbial fork in the road: how to bridge the knowledge of self with that of the rest of the world. Descartes’ answer to this is to prove the existence of God. The purpose of this essay will be to state and explain Descartes' Third Meditation: Proof of God's Existence by identifying relevant concepts and terminology and their relationship to each other and examining each premise as well as the conclusion of the proof and finally

As with almost all of Descartes inquiries the roots of his second argument for the existence of God begin with his desire to build a foundation of knowledge that he can clearly and distinctly perceive. At the beginning of the third meditation Descartes once again recollects the things that he knows with certainty. The problem arises when he attempts to clearly and distinctly understand truths of arithmetic and geometry. Descartes has enough evidence to believe these things, but one major doubt is still present; the possibility of God being a deceiver. Descartes worry is that all the knowledge that he possesses through intuition could potentially be false if God merely chooses to deceive him. So in order to have a clear and distinct perception of arithmetic truths (and other such intuitive truths) Descartes delves into the question of God’s existence (and whether this God could be a deceiver or not).

Descartes’s attempt to prove the existence of God begins with the argument that he has the clear and distinct idea of God as the “most perfect being and that there must be at least as much reality in the efficient and total cause in the effect of that cause” (40). Therefore, this idea of God can’t be from himself, but its cause must be God. So God exists. In what follows I’ll explain these terms and why the premises seemed true to him.

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 first part in which one can prove that there is a God is based on change. In the first part, Aquinas mentions that things change and that there has to be something which brings about that change, but at the same time is changeless. Aquinas states that “a thing in process of change cannot itself cause that same change; it cannot change itself” (Aquinas 45). For example, he gives an example about wood and fire. The wood is able to be hot but simply cannot make itself change without having an outside source that will cause it to become hot. The fire, that is naturally hot, will indeed make the wood hot and as a result, will change the wood.

To further validate his proof, he attempts to show God’s existence as an a posteriori claim. Descartes states that as humans we have the idea of God in our minds. We conceive God as a perfect being, that of perfect existence. As shown in the quote from page 37, this idea of God is beyond our reasoning to create, and must have come from God itself. Our idea of God certifies his existence. Descartes deviates from the method again, and his reasoning fails to provide an absolute proof.

You can find Descartes’ proof of the existence of God in the Third Meditation. Although to understand this argument you have to look at his previous meditation where he begins to build his argument with the notion that in order for him to think, he must exist. From this observation, Descartes’ sees that the idea of his existence is very clear and distinct in his mind. Based upon this clarity and the fact that he has just determined his own

The Meditations on First Philosophy by Rene Descartes is a thorough analysis about doubt. Descartes describes his method of doubt to determine whether he can truly know something. One of his major arguments is the proof of the existence of God. In this paper, I will attempt to unravel the flaws in Descartes proof that God exists.

Rene Descartes Meditations is known to be one of his most famous works, it has also shown to be very important in Philosophical Epistemology. Within the meditation’s he provides many arguments that remove pre-existing notions, and bring it to the root of its foundation which Descartes, then will come up with his indubitable foundation of knowledge to defeat any doubt and to prove God is real. Descartes was a “foundationalist”, by introducing a new way of knowledge and with clearing up how people thought about things prior. Descartes took knowledge to its very foundations, and from there he can build up from it. In this essay, I will be discussing Descartes, and analyzing his first two meditations and arguing that he does indeed succeed in his argument.

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.

The final crucial proof of the existence of God is Aquinas fourth proof. This proof looks at qualities of humans; all humans possess many different attributes which we consider unique to each individual. This is when standards are formed humans began to have a certain criteria for how or what someone with a given attribute should act or how they should portray themselves. The only way this standard could come into existence is to believe that there is a perfect creation possessing all qualities and expressing them in the most precise and perfect way. This perfect creation is God, the person in which humans get the laws at which the obeyed by. Aquinas five proofs of the existence of God are much more extensive but just looking at the proof of motion and the proof of perfection it becomes unquestionable that there is an almighty creation. This superior creation creates laws at which
