In this paper, I will explain how Descartes uses the existence of himself to prove the existence of God. The “idea of God is in my mind” is based on “I think, therefore I am”, so there is a question arises: “do I derive my existence? Why, from myself, or from my parents, or from whatever other things there are that are less perfect than God. For nothing more perfect than God, or even as perfect as God, can be thought or imagined.” (Descartes 32, 48) Descartes investigates his reasons to show that he, his parents and other causes cannot cause the existence of himself.
The purpose of my essay will be to examine Descartes' argument for the existence of God. First, I will discuss Descartes’ proof for the existence of God then I will critique the argument of his existence. Lastly, I will point to some complications and problems that exist within the proof. Descartes’ proof of the existence of God is presented in the Third Meditation. He shapes his argument on the proof in the Second Meditation that in order for Descartes to think he must exist. From this specific examination he realizes his existence is very clear and distinct in his mind because of the fact he had just discovered his own existence. He then creates a rule that whatever things he sees are clear and distinct, are all true. Descartes begins his proof by splitting his thoughts into four categories, which consist of ideas, judgments, volitions, and emotions. He then further analyzes these categories to decide which thoughts might consist of error.
Up until the Third Meditation, Descartes arguments made sense with minor flaws, but not every argument is perfect. Trying to prove God’s existence… I believe that people should not being trying to prove whether or not God is real. As Pascal said, “If there is a God, he is infinitely beyond our comprehension, since, being indivisible and without limits, he bears no relation to us… That being so, who would dare to attempt an answer to the question? Certainly not we, who bear no relation to him” (Pascal
Descartes goes on to prove the existence of God in two different ways. His arguments rely on that fact that we have a clear and distinct idea of God. The first way is the cosmological proof where the idea that something cannot come from nothing because something has to exist in order to create something else. As a finite being, it would be impossible for us to come up with an idea for something or someone
Aquinas argues that “Perhaps not everyone who hears this word "God" understands it to signify something than which nothing greater can be thought”, thus Descartes’ argument is only plausible for those who view God in the same light that he does. Nevertheless, this criticism is easy to solve. If we replace the word “God” with “a being than which none greater can be conceived”, then we instead establish that a being of which none greater can be conceived exists, and we naturally assume that this being is God. Nonetheless, Aquinas continues with a second flaw in Descartes argument, the lack of establishment between physical and mental existence. In light of Aquinas’ criticism, it becomes apparent that Descartes’ argument does nothing to show the physical existence of God. In Axiom X ,Descartes claims “Existence is contained in the idea or concept of every single thing, since we cannot conceive of anything except as existing”. However, this does not prove that God exists, for example, if I imagine a unicorn, this proves the mental existence of unicorns, however it does no such thing for the physical existence. Therefore, Descartes premise may be true, but it fails to be specific enough to make a convincing
In Descartes’ second meditation, he offers up an argument for Defective Nature Doubt that brings forth the idea that we can’t be certain of anything we perceive being actual and real (153). Descartes thinks that there is a possibility that we are constantly being deceived due to the fact that we don’t know, with perfect certainty, know where our ideas originate from (154). He tries to describe a method in order to dispel this Defective Nature Doubt by giving an argument for the existence of God. I think that the argument he gives for the existence of God is valid, yet I find it to be unsound due to the fact that a few of his premises are can easily be debated. In order to express this opinion, I will first provide explanations of the premises and conclusions of the argument, and then I will critique the premises that I find to be inadequate in order to support my opinion that Descartes’ argument is valid but unsound.
If looked at closely, one thing that comes out in the open is that the ontological argument given by Descartes differs from the original explanations of the ontological argument. The model for the majority of conventional deductions is the ontological argument presented by St. Anselm in the Proslogium II. Interpreted loosely, Descartes argument means that his notion of God is that of a superlatively perfect being. In itself, existence is excellence. In reality, God must exist or else the idea that one has about God would lack any form of perfection and as expected this would be illogical. The core of God is confined in the idea of existence just like the essence of a triangle revolves around its three sides (Platinga 11).
From Descartes' perception, nature is a depiction of God; therefore, God must fundamentally exist, to the extent that as he, too, is an outcome of His own creation. Descartes was one of many thinkers who fully braced this argument in support of God's actuality, challenging that the external world is the dominant force behind the existence of all persons. Descartes' claims, as depicted inside the scholarly borders of Meditations on First Philosophy, were created not in astrophysical or ontological quarrels but rather in teleological debate, to the extent that the philosopher thought that there has to be an all-powerful entity accountable for all the drive and command that is found within physical life and, thereby, encouraging a sense of marvel about the world.
Descartes argues that we can know the external world because of God, and God is not a deceiver. Descartes’ core foundation for understanding what is important comes from three points: our thoughts about the world and the things in it could be deceptive, our power of reasoning has found ideas that are indubitable, and certainty come by way of reasoning. Once we have a certainty of God, and ourselves then we are easily able to distinguish reality from dreams, and so on. God created us and gave us reason, which tells us that our ideas of the external world come from God. God has directly provided us with the idea of the external world. The concept of existence, the self, and doubt could not have existed on its own; therefore they had to be created by someone to have put them in our mind. That creator is God, who is omnipotent and perfect. God is not a deceiver to me; God is good, so therefore what I perceive really does exist. God without existence is like a mountain without a valley. A valley does not exist if there is no mountain, and vice versa a mountain is not a mountain with out a valley. We cannot believe or think of God without existence. We know the idea of God, and that idea inevitably contains his existence. My thought on god is clear and distinct that he is existent. Descartes’ now has ‘rebuilt’ the world, solely because of his power and reasoning. Descartes’ is only able...
According to Descartes, “because our senses sometimes deceive us, I wanted to suppose that nothing was exactly as they led us to imagine (Descartes 18).” In order to extinguish his uncertainty and find incontrovertible truth, he chooses to “raze everything to the ground and begin again from the original foundations (Descartes 59).” This foundation, which Descartes is certain to be the absolute truth, is “I think, therefore I am (Descartes 18).” Descartes argues that truth and proof of reality lies in the human mind, rather than the senses. In other words, he claims that the existence of material objects are not based on the senses because of human imperfection. In fact, he argues that humans, similarly to Plato’s Allegory of the Cave, are incapable of sensing the true essence or existence of material objects. However, what makes an object real is human thought and the idea of that object, thus paving the way for Descartes’ proof of God’s existence. Because the senses are easily deceived and because Descartes understands that the senses can be deceived, Descartes is aware of his own imperfection. He
