Explain Descartes Version Of The Ontological Argument
Explain Descartes version of the ontological argument?
Ontology is the branch of philosophy that explores the whole concept of existence. Thomas Aquinas argued that a reason as to why the ontological argument does not work is that we do not know what God is, Descartes disagreed with this.
Descartes, who was a very influential mathematician, philosopher and scientist, believed, similarly to Anselm and Plato previously, that human beings mind’s are imprinted with concepts such as equality, cause, shape and number as well as an understanding of what God is which we all share from birth. We have an intrinsic understanding that God is the supremely perfect being and is perfect in every way. By ‘perfect’, Descartes means omniscience, omnipotence ad omnibenevolence.
Descartes used an analogy of a triangle to explain his understanding of how this innate idea demonstrated the existence of God. He claimed that by comparing it to the way we ordinarily establish very basic truths in arithmetic and geometry, such as that the number two is even or that the sum of the angles of a triangle is equal to the sum of two right angles. We intuit such truths directly by inspecting our clear and distinct ideas of the number two and of a triangle. So, likewise, we are able to attain knowledge of God's existence simply by apprehending that necessary existence is included in the clear and distinct idea of a supremely perfect being.
Descartes also used an analogy of a mountain; he said that the existence of God is part of the essence of God, like a valley is part of the essence of a mountain. He recognised that this had its limitations, while we might be able to think of a mountain without thinking of a valley additionally, this does not mean the combination in our imagination actually exists in the real world. However, Descartes argued that his nature does not involve angles or valleys but perfections; therefore existence is a perfection because God has all the perfections, and existence

    In Discourse on Method by René Descartes, the author starts by expressing his methodology and thought process in the effort to determine his own existence. While the topic of this piece starts by focusing on Descartes and the truth he was searching for about his existence, it quickly turns to the topic of the truth or existence of something more perfect than himself. That more perfect example being God.…

    If he had not reached the metaphysical certainty of the self, it is likely that he would not be able to find any metaphysical certainty at all, including that of God’s existence. From this, Descartes then moves on to go about proving the existence of an omnipotent, omnibenevolent, infinite, omniscient God. Before discussing Descartes’s proof of God’s existence, it is important to first discuss ideas, substances, and their realities. According to Descartes, ideas are formed in the human mind in three ways. Ideas are either experienced or perceived in the world, they have been created or invented, or they have been derived from one’s own nature.…

    It is not obtained through sense perceptions. This is a reason that supports his claim that finite substances, such as the human mind, are not capable of creating such a omnipotent, omnibenevolent, infinite, omniscient God. He goes on to claim that the idea of God is innate, a concept that is present, or “imprinted”, in the human mind from birth. Descartes strongly believes that innate ideas are the necessary things that provide a reliable basis for all metaphysical knowledge. The idea of God is clearly and distinctly perceived. Descartes does admit, however, that he cannot grasp the thought of God’s existence, but that he merely understands it. Due to his conclusion that God ultimately exists, he is now able to trust the external world with…

    Cartesian Dualism Flaws

    • 1061 Words

    Descartes thinks that since we all have an innate idea of a perfect being, then that perfect being, which he calls God, has to exist, or else it would not be perfect anymore. There are two problems with this line of thought. First, do we really have an innate idea of a perfect being? Wouldn’t we need to acquire the concept of “perfect” and “being” first? It is true that we could not have directly seen or experienced a perfect being in real life, but that does not mean the idea of a perfect being has to be innate. Rather, we can form this idea merely by experiencing non-perfect beings and imagining the opposite, just like how we develop the idea of immaterial things after we have seen or experienced material things. Therefore, the idea of a perfect being is not innate, and in fact, it is possible for us never to have that idea at all. On the other hand, why must a perfect being exist? Why should existence be better, “more perfect,” than non-existence? Descartes does not give us enough evidence of the “perfectness” of existence, and thus existence cannot be guaranteed as an essential part of the perfect being’s property. Now I have shown that Descartes’ main argument for God’s existence is flawed, although I still do not rule out the possibility of God’s…

    Descartes vs. Aquinas

    • 505 Words
    • 3 Pages

    I found Descartes’ way of thinking very interesting when compared to Aristotle. Descartes doubts the existence of God when he decides to start over and completely ignore his senses. He states in his third meditation, “…and I do not yet even know for sure whether there is a God at all…I must examine whether there is a God, and if there is, whether he can be a deceiver.” (25) Descartes makes a goal for himself to find out if there is a God and who he is. According to Aquinas we will never be able to understand who or what God is. We are finite and so we cannot understand the infinity of God. We can only know He is and always will be because He has instilled that bit of knowledge within us. So when Descartes says we cannot have the idea of finite without the idea of infinite, he claims we understand what God is. But I would disagree and take Aquinas’ side because what Descartes is understanding is not who God is entirely; it is an idea of what he is like. We as human beings, can contemplate God and try to understand what makes him, him. But since we are so limited in our knowledge, we will never comprehend our God. Later on page 32, Descartes starts to say it does not matter that he does not grasp the infinite only that he understands it. In line 47 he says he sees no reason that his knowledge cannot increase to infinity and use that infinite knowledge to understand all of the other perfections of God. This idea cannot ever happen because we humans have a beginning. God is the one who made us, but no one made God. His knowledge is truly infinite because he, himself has no beginning and no end. We on the other hand were born, will die, and though are spirits will join God in heaven, he can still choose to end our spirits existence. I began to agree with Descartes as he realizes that even if his knowledge increases more and more, it will never actually be infinite because it will never reach the point where it can no longer increase. (pg 32) I liked his quote. ” God,…

    According to this principle, the reality of the cause must be greater than or equal to the reality of the effect. The idea of God has infinite reality and, by theory, the only cause of this infinite idea can only be God. With all this said, the reality of God is the only plausible cause to the reality of the idea of God. Descartes gives another proof in Meditation Five where he has reasoned that a triangle must have all the properties he assigns to it, because the triangle exists as an idea in his mind and he clearly and distinctly perceives all these properties. He then reasons, by analogy, that God exists as an idea in his mind and he clearly and distinctly perceives all of his qualities. One of these qualities is existence, so it follows from his clear and distinct perception that God must exist. If existence is the essence of God, then God would not be God if he did not exist, just as a triangle would not be a triangle if it were not three-sided. At the very least, then, the existence of God must be as certain as the properties of mathematical and geometrical objects since he can prove them in the same way. Having concluded that God must necessarily exist, Descartes goes further and then asks how he received the idea of God. He could have not invented the idea. Therefore, the idea must be innate which, according to Descartes, means that God must have created him…

    Rene Descartes in his Discourse of the Method begins with the problem of showing and proving his own existence, but later in the reading changes the problem and it is concentrating on proving the existence of God. The first time that I thought to myself that this reading is probably about something else than proving his own existence was where the author started talking about perfection. The author defined God as “something that truly was more perfect than I was, something indeed having perfections of which I could have any idea” (Descartes, 2010, p.16).…

    He then makes a claim that states effects aren’t ever realer than their causes, which means something ‘perfect’ must exist to be able to have the idea of ‘perfection’. Descartes goes on to say that he knows he isn’t ‘perfect’ and since he isn’t ‘perfect’, who could have put this idea in his head? His answer is something ‘perfect’, and that something ‘perfect’ must be…

    Once upon a time, there was a goddess named Jasmine. She rose from the lands of Magic City. She was the main god. She ran Magic City. She had two children and a magical Lady Bug that could talk. Even though Jasmine looked like the modern everyday woman, she wasn’t. She had powers that she passed down to her children Jaidyn and Julanii. Julanii was only a baby. But Jaidyn was a teenager, 16 to be exact. The family lived in Magic City for years. But Jasmine thought it was time for them to go out in the “real” world. So they moved to Maryland. Jaidyn was enrolled into Fairmont Heights High School. But there was a specific reason why Jasmine wanted to move. She wanted to send Jaidyn on a quest of helping and saving people in any kind of danger. She wanted to test her superhero qualities. Jaidyn had many of them. She had the ability to fly, read people’s minds, invisibility, and she had super speed. Her first day of school went by, and she actually made a lot of new friends. As weeks went by Jaidyn began to love her new life. Until one day, her superhero abilities were tested. She was walking home after school. She walked passed an alley to get to her house. When suddenly she heard a female’s scream and a man yelled “Give me the money!” Jaidyn knew what she had to do, she had to help her. But she didn’t want to be seen. All she had to protect her identity was a ski mask in her book bag. Slowly she put it on and flew to the scene. The man released the woman from his arms and she ran out of the alley. Jaidyn fought off the criminal, tied him up, and called the cops. When the police arrived they praised Jaidyn for her good work and took the man too jail. Jaidyn was the talk of the town since that day. But no one really knew who she was. All they saw her as was a girl in a ski mask. She continued to keep her identity as a secret. When Jaidyn and her family were watching the news one day, she saw that they were talking about “The girl in the ski mask”. It’s not much she…

    From the beginning of the third meditation, Descartes seeks to establish the existence of God using his initial concept of self awareness. Descartes argued that because he thought, then he lived. Thinking ability at this time was linked to being alive and thought that there must be a god who puts the thoughts in his mind. In his quest for indubitable truth, Descartes came up with the theory of ideas, which classified those things that he considered distinct and clear to be true. Descartes argued that the idea of god should be coming from within him since he cannot experience god himself directly or find any perfection in himself.…

    Descartes also states that this argument isn’t strong enough to prove that God exists. Because he has been constantly revising his believes he says that at this point he can easily tell the difference between essence and existence. After he points that out he explains that he believes that God could be separated from the existence but not from his essence. Then he contradicts himself saying that not existing would be prove of him not being perfect thus he had to exist. After that Descartes starts lacking of confidence that God exists. He thinks that he is giving some attributions, being perfect; to a creature that he doesn’t even know if exists. He thinks that he is just matching two things that he knows to make something new, something that…

    He starts with the idea of a God who is eternal, infinite, and perfect. In the beginning of Meditations on First Philosophy, He explains that “we must believe that there is a God, because we are so taught in the Holy Scriptures, and, on the other hand, that we must believe the Holy Scriptures because they come from God “(Descartes 1). He then doubts himself if god does really exist. Through examining his thoughts, he ends up believing that the idea of God exists because of his innate idea of God which has to be God who “is the cause of this idea”(Descartes 25). Descartes then explains more in depth saying, “I have no choice but to conclude that the mere fact of my existing is and of there being in me an idea of a most perfect being, that is God, demonstrates most evidently that God too exists” (34). Another reason is how in his further mediations, he explains how if God does not exist, then he is not a supremely perfect being. Saying that God does not exist, we can imagine a being that is more perfect than God. But this is a contradiction because since the idea of God is the idea of the most perfect being of all. Therefore, God must exist because you cannot image a more perfect being than god, who he is the almighty and perfect of…
