Describing a System of Knowledge

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:

In the Meditations, Rene Descartes attempts to doubt everything that is possible to doubt. His uncertainty of things that existence ranges from God to himself. Then he goes on to start proving that things do exist by first proving that he exists. After he establishes himself he can go on to establish everything else in the world. Next he goes to prove that the mind is separate then the body. In order to do this he must first prove he has a mind, and then prove that bodily things exist. I do agree with Descartes that the mind is separate from the body. These are the arguments that I agree with Descartes.

At the beginning of Meditation three, Descartes has made substantial progress towards defeating skepticism. Using his methods of Doubt and Analysis he has systematically examined all his beliefs and set aside those which he could call into doubt until he reached three beliefs which he could not possibly doubt. First, that the evil genius seeking to deceive him could not deceive him into thinking that he did not exist when in fact he did exist. Second, that his essence is to be a thinking thing. Third, the essence of matter is to be flexible, changeable and extended.

Something very essential to know about Descartes is his idea of Cogito Ergo Sum; I think, therefore I am. He believes that he exists because he is thinking, making him a thinking thing. Descartes first premise states, "I have a clear and distinct idea of myself, in so far as I am simply a thinking, non-extended thing" (Descartes, 54). The first thing that we need to understand from this premise is what Descartes means by extended; to occupy space. So, since he believes that he is not an extended thing, it follows that he does not take up space. Given this, he looked inside himself and saw no parts within his mind, no space or boundaries that his mind contains. In addition, the mind provides a place for free will and faith, which are not parts but different ways of thinking. He rationalizes this by making the mind of a qualitative substance. By saying that only things that can be measured must be of a material substance and those things that cannot be measured are of a thought like substance. The relation between body and mind now seem to be more divided since he believes that his mind is not extended. In short, this premise states that the mind has no parts, making it indivisible.

The First Meditation of Meditations on First Philosophy, subtitled "What can be called into doubt," opens with the Meditator reflecting on the number of falsehoods he has believed during his life and on the subsequent ability of the body to deceive him. Seated alone by the fire, he resolves to demolish former opinions and rebuild his knowledge on more certain grounds.

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.

Descartes’ method offers definitive conclusions on certain topics, (his existence, the existence of God)but his reasoning is not without error. He uses three arguments to prove existence (His and God’s) that attempt to solidify his conclusions. For his method to function seamlessly, Descartes needs to be consistent in his use of the method, that is, he must continue to doubt and challenge thoughts that originate in his own mind. He is unable to achieve this ideal state of mind, however, and his proofs are shown to be faulty.

By its conclusion, Descartes has seemingly subjected all of his beliefs to the strongest and most hyberbolic of doubts. He invokes the nightmarish notion of an all-powerful, malign demon who could be deceiving him in the realm of sensory experience, in his very understanding of matter and even in the simplest cases of mathematical or logical truths. The doubts may be obscure, but this is the strength of the method - the weakness of criteria for what makes a doubt reasonable means that almost anything can count as a doubt, and therefore whatever withstands doubt must be

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).

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.

Descartes attacks the possibility of certainty with regards to the existence of small and universal elements with the possibility of our thoughts being altered by an omnipotent deceiver. In paragraph nine, he states, “How do I know that he did not bring it about that there be no Earth at all, no heavens, no extended thing, no figure, no size, no place, and yet all these things should seem to me to exist precisely as they appear to do now.” His point is that this omnipotent evil deceiver could create in our minds an understanding of mathematics and logic that is at odds with reality, causing us to construe everything wrongly. Thus Descartes ends this final and devastating doubt with the preliminary conclusion that everything he perceives can be called into doubt.

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

     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

How can I doubt something if I do not exist. By the same token, maybe I am deceived into thinking I don’t exist by some other entity. But then I must exist for it is I who is being deceived. This is the basic premise of Descartes’ famous Cogito Ergo Sum – I think therefor I am. Here Descartes is not saying anything about what we are here, just that we are. Next his desire is to find out exactly what he is. Well, Descartes states, if I exist, for how long do I exist? I exist for as long as I think, and if I cease to think, then I shall also cease to exist. Therefor, I am nothing but a thinking thing – that is, a thing that “doubts, understands, affirms, denies, wills, refuses, and that also imagines and senses.'; Although saying he is all of these things is indeed a bold statement, Descartes feels that in his attempt to prove that he exists he has done all of those things, therefor they must be a part of what he is.

It is difficult for me to conceive of a thought with more frightening implications than that which leads me to contemplate whether every element of knowledge I assume could conceivably be uncertain in reality. Rene Descartes set out to do just that in one his most famous works, entitled Meditations of First Philosophy; having realized that the beliefs he employed on a daily basis were flawed, Descartes began pursuing a foundationalist framework of knowledge that would enable him to develop certainty from his beliefs. While I agree with Descartes’ notion that the belief of which I can be most certain is my own existence as a thinking thing, I hold that he puts far too much emphasis on his questionable arguments specifically related to the
