Essay about Assessment of Descartes' Claims About the Existence of God

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.

Descartes is considering that all of his experiences could be false and that everything is just the invention of a powerful being. This resulted in this argument:

I have an idea of a perfect being; it must contain in reality all the

From Descartes point of view, he thinks that it makes sense to talk of degrees of reality to qualify the above assumptions, and he sometimes equates this with talk of degrees of perfection. Thus, he brings God back into the picture. The ideas, then, could come from only God, or from another being superior to humans but inferior to God. But this, too, is impossible, argues Descartes, as if it were the case that God produces the ideas of bodies in humans, then the very strong inclination we have towards believing that the idea-producing bodies resemble the ideas we have would be false and thus God would be allowing us to be deceived which is not permissible. The same would apply if any other being were producing

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.

The highest degree of reality involves the infinite. The infinite represents substances that are unbounded and possess no conceivable or tangible limits in any of their aspects or qualities. The only example of this for Descartes would be an entity of omnipotence, who would be all knowing, all powerful, and that of which no greater can be conceived, in other words God.

There has been many thinkers in history who have lacked a belief in God. Some ancient Greek philosophers, such as Epicurus, obtained natural explanations for these superior miracles. Epicurus was the first to question the compatibility of God with suffering. In contrast, Descartes proves God 's existence as an external reality and that ideas of perfection or infinity cannot come from oneself. He explains that “I am a finite being and thus cannot generate these ideas on my own. I have also never experienced perfection or infinity in the world, so they cannot come from experience, either”. God is a “perfect being”.

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.

Descartes is able to examine ideas and gain knowledge form them. Innate ideas mean they are present at birth, in other words we are implanted with certain ideas at our creation. He often uses ‘innate ideas’ to explain the mind’s original programming. “An infant’s mind is programmed with the rules of logic. Consider as an example the valid rule, modus ponens. Let P and Q stand for variables… the rules states that, if P then Q is true and P is true, then it follows that Q is true. We know that we are programmed with this rule because young children, who have never studied logic and have never entertained the rule, when given an argument in which the variables above are replaced by actual sentences, are able to intuit the validity of the argument.” Descartes believed our minds are programmed with eternal truths, “Whatever comes into existence must have been brought into existence by something else.” He also discovers that the idea of God is only part of his initial programming but also that God, operating through secondary sources such as his parents, is the programmer.

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

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

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 discusses the existence of the human mind as a separate entity from the human body, including the a passage confirming his own existence as nothing but a thinking entity, in his writing Principles of Philosophy (I. 63-65). Following his rejection of all knowledge, in order to divide what was false from what could be proven, Descartes strives to prove the existence of his own mind, as a basis from which to prove the existence of the rest of the universe. I think his premise is flawed, Through the concept of doubt, he finds a contradiction (I am thinking about not
