Essay about The Existence of God: the Arguments of Locke and Descartes

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 pointing out the difference between the existence of God and the existence of a mountain. Finite things, says Descartes, have possible or contingent existence. For example, a finite thing such as a mountain relies on volcanic forces and weathering to bring it in and out of existence. Necessary existence on the other hand is contained in the idea of God. Therefore, God does not need anything to bring him in and out of existence.

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 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.

This then leads him to question the existence of God, and then whether he himself truly exists as well. Descartes concludes his claim in stating, “So after considering everything very thoroughly, I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind,” (25). Therefore, in spite of everything he is skeptical of, Descartes manages to believe that his true existence is not something worthy of doubt.

The existence of God has always been an arguable topic. Descartes’ however, believed that he had proof of God’s existence through an intense analysis of the mind. Throughout this paper I will discuss what he has provided as proof and some of the complications that arise throughout his argument.

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.

Socrates once said, “As for me, all I know is that I know nothing.” Several philosophers contradicted Socrates’ outlook and believed that true knowledge was in fact attainable. This epistemological view however had several stances to it, as philosophers held different beliefs in regards to the derivation of true knowledge. Rationalists believed that the mind was the source of true knowledge, while in Empiricism, true knowledge derived from the senses. Rene Descartes, a rationalist, and John Locke, an empiricist, were prime examples of epistemologists who were seen to differentiate greatly within each of their philosophies. However, although Descartes and Locke’s ideas did contrast in that sense,

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

     Locke instead is an empiricist, and therefore he directly critiques Descartes epistemic system and tries to establish his own foundation of knowledge. Locke believes that our knowledge of the world comes from what our senses tell us. Locke’s theory state that we are all born with a blank slate, tabula rasa, before we

Like Descartes, Locke also believed in an external world. As an empiricist, Locke relied heavily on the senses to provide true knowledge (Moore 2002). He shared Aristotle’s belief that the mind is a blank slate, also known as tabula rasa, at birth (Paquette 211). Our sense experiences thereafter provide us with knowledge to fill in those slates (Paquette 211). In Locke’s “Representative Theory of Perception,” also known as Epistemological Dualism, he stated that material objects exist and are separate entities from human beings (Paquette 227). However, he also believed that objects exist in the mind as psychological entities (Paquette 227). Locke concluded that people can taste, smell, touch, and see the external world which, in turn, becomes impressions in our minds (Paquette 227). Descartes and Locke are thus seen to be similar in the sense that they both believed in an external world.

A standout amongst the most questionable, disputable topics has been the presence of god. There are various regular arguments for the presence of God. Descartes is one of many, he trusted in himself that he had affirmation of God's quality through an extraordinary examination of the mind. Descartes has more than one of many thoughts. To start Descartes ask "how would I know that I exist? As covered in my presentation Descartes wants to demonstrate that there is no evil spirit that is always deceiving him. Remembering the true objective to do this; he leaves to show that he has the unmistakable and a particular thought that God is incredible and can't along these lines mislead him. This is done by recommending the considerations can have more prominent reality. For Descartes Existence is conventional and those things that exist are more flawless or all the more awesome then those things that don't. Descartes suggests that there are three sorts of thoughts: Innate, Invented, and Adventitious. Innate thoughts are and have reliably been inside us, Fictitious or imagined contemplations begin from our imaginative energy , and Adventitious considerations start from experiences of the world. He contends that the possibility of God is Innate and set in us by God and he dismissed the likelihood that the possibility of God is Invented or Adventitious.

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.

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.
