Descartes Meditations On First Philosophy

Descartes says that examining this idea leads to the realization of the existence of God. His argument initially encompasses the acknowledgement of such an idea. The idea of God is a being that is omnipotent and infinite, as well as the creator of all things. Descartes then moves onto the Casual Adequacy Principle. This principle infers an object must have as its cause something that has the same (or more) attributes as the object.

Prior to his method on error, Descartes has already proven a pair of foundational beliefs. In meditation one, Descartes proved that he was “a thinking thing” and that in order to be a thinking thing, “I exist”. In mediation three, he proved that God exists due to the fact that in order to have an idea of God, one must already have the idea innately implanted in their mind. Since Descartes is finite he believes that God innately implanted the thought of an infinite perfect being in his mind, so therefore God exists.

Descartes describes humans as being finite and God as infinite based on formal and objective reality. Formal reality is everything that is real in the physical world and finite, while objective reality is a function of an idea’s representational content. Applying the objective reality to God, Descartes states “the idea that gives me my understanding of a supreme God… certainly has in it more objective reality than the ideas that represent finite substances.” (Descartes, Cottingham 40) Also, he believes that a cause has to have as much reality as the effect, because things cannot be formed from nothing.

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 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.

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.

Given the above arguments one can begin to understand the nature of the God Descartes is endeavoring to prove. For Descartes, God is infinite and perfect existence. God is “eternal, immutable, independent, supremely intelligent, supremely powerful, and [the creator of] everything else". (Descartes 20) Not only does God possess this nature but it is necessary that He does so. If God is not infinite or perfect God could not exist as these attributes are essential to God's existence. Furthermore, if God is not the ultimate creator the innate idea of God we experience would cease to be innate but adventitious (externally caused) or imaginative (caused by the mind) which is again impossible given its content. Given these qualities one can draw a connection to the

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

Rene Descartes in his book Meditations on First Philosophy gives two distinct and valid arguments into the existence of God, which he explains in the Third Mediation and the Fifth Meditation. In the third meditation Descartes explains God as a substance that is eternal and extremely powerful. He calls these objective realities in which make up only a little of what God truly is. He goes onto explain that must have far more than just objective reality but formal reality as well. He knows that the concept of an everlasting and all-powerful creature couldn’t have been created in him and comes to the conclusion of something (God) being the culprit of this idea of him.

In another word, the idea of God must come from something infinity and having the most perfection, and Descartes is finite and imperfect, given that his knowledge is increasing. Accordingly, the cause of the idea of God must be God. In addition, he also eliminated the possibility of this idea of God could be “materially false”, and thus have come from nothing. However, we can straightforwardly tell from the natural light that the idea of infinity and supremely perfect is true in highest degree, it can’t be nothing.(p14) Therefore, Descartes having an idea of God proves that God

He states, "From the fact that I cannot think of God not existing, it follows that existence cannot be separated from God and thus that he actually exists." (298) The existence of God is something that cannot be separated, just as we cannot separate the idea of an ocean without sand. Descartes explains that man is a finite

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

Descartes explains in his book Meditations the reason for why God exists and how the person behind the infinite and perfection is no one else but God himself. “The idea of substance be in my mind owing to this, that I myself am a substance… unless it were given me by some substance in reality infinite…and it cannot be said that this idea of God is perhaps

From this definite foundation Descartes tries to prove that there is something external to the mind. So he states the law of casualty. This basically says that nothing can be created from nothing, and that the less perfect can not create something more perfect or better than itself. Then if there is an idea in our minds that we didn’t create, something else created it. If God is more perfect than us, then we could not have created God but God created us. Descartes then wrote about the idea of God. He said that God is infinite and could not have been created by us because God is more perfect than us thus undoubtable and certain. The idea that God exists disproves the Evil Genius theory therefore proves the existence of an external world.
