Descartes : The Father Of Modern Day Philosophy

Secondly, to come up with the second proof of Gods existence, Descartes thought that the power and action that is needed to preserve something is capable of creating something new. He argued that there must be as much power in the cause just as it is in the effect. According to the philosophical writings of Descartes, upon knowing that he did not have power to preserve his own existence because he was just a thinking thing; Descartes concluded that the power must have come from outside him (Descartes, Cottingham and Murdoch 26) And since he is a thinking thing, he claims that the one who created him must also be a thinking thing, possessing all the ideas and attributes of god. In addition, he observed that his parents could not be responsible for creating and preserving his life. Descartes therefore concludes that the one who created him and gave him ideas of a perfect God must be God, therefore God exists.

In Rene Descartes, Meditations on First Philosophy, Descartes does and experiment with wax to try to prove that things actually exist in this world. This essay is going to prove how we can tell that things actually exist and what can perceive the wax.

After giving his first proof for the existence of God Descartes concludes by mentioning that this proof is not always self-evident. When he is absorbed in the world of sensory illusions it is not quite obvious to him that God’s existence can be derived from the idea of God. So to further cement God’s existence Descartes begins his second proof by posing the question of whether he could exist (a thinking thing that possesses the idea of an infinite and perfect god) if God itself did not exist.

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.

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.

The existence of God has been a question since the idea of God was conceived. Descartes tries to prove Gods existence, to disprove his Evil demon theory, and to show that there is without a doubt something external to ones own existence. He is looking for a definite certainty, a foundation for which he can base all of his beliefs and know for a fact that they are true.

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

In the meditations, Descartes evaluates whether or not everything we know is a reality or a dream. Descartes claims that we can only be sure that our beliefs are true when we clearly and distinctively perceive them to be true. As the reader analyzes the third meditation, Descartes has confirmed that some of his beliefs are in fact true. The first is that Descartes himself exists. This is expressed in what has now become a popular quote known as the “Cogito” which says, “I think therefore I am. His second conclusion is that God exist and that he is not a deceiver. Descartes then presents his arguments to prove the existence of God. He argues that by nature humans are imperfect beings. Furthermore, humankind could not possibly be able to comprehend perfection or infinite things on their own. He writes, “By the name of God I understand a substance that is infinite, independent, all-knowing, all powerful, and which myself and everything else…have been created.”(16) Descartes uses this description of God to display the distinction between God and man.

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

His belief in God even affected his theories on reality. One of his theories was that he was being deceived by a conniving and mischievous demon that was hell-bent on distorting his reality. The demon could be comparable to the evil dictator and the memory replacing machine in Total Recall. Despite the evil demon, Descartes did manage to reveal one very true thing and that is that he must exist if he truly is being deceived by the evil demon because he needs to exist in order to be deceived. He later summarizes this into his famous phrase “I think, therefore, I am.”(Descartes 136).

In the Third Meditation, Descartes forms a proof for the existence of God. He begins by laying down a foundation for what he claims to know and then offers an explanation for why he previously accepted various ideas but is no longer certain of them. Before he arrives at the concept of God, Descartes categorizes ideas and the possible sources that they originate from. He then distinguishes between the varying degrees of reality that an idea can possess, as well as the cause of an idea. Descartes proceeds to investigate the idea of an infinite being, or God, and how he came to acquire such an idea with more objective reality than he himself has. By ruling out the possibility of this idea being invented or adventitious, Descartes concludes

It is from this thought that Descartes is able to determine God exists and create his first

     Through his philosophical search Descartes was able to find one indubitable certainty, that we are thinking beings. We always think, even when we have doubts that we are thinking we are still thinking because a doubt is a thought. Although Descartes found this one universal truth, he was still not able to believe in anything but the fact that he was a thinking being. Therefore he still doubted everything around him. He used this one certainty to try to find a system of knowledge about everything in the world. Descartes idea was to propose a hypothesis about something. For example he might say that a perfect being was in existence. He would go around this thought in a methodical way, doubting it, all the while trying to identify it as a certainty. Doubting everything was at first dangerous because in doubting everything he was also admitting that he doubted the existence of God, and thus opposing the church. However he made it a point to tell us at the beginning of his Discourse on Methods that what he was writing was only for himself and that he expected no one but himself to follow it (Descartes 14, 15). Descartes eventually managed to prove the existence of a higher being. He said that since he had the idea of a perfect being, then that perfect being must exist. His

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.
