Rene Descartes Research Paper

From the various books he’s written to the pension granted from the King of France, renowned philosopher and mathematician René Descartes accomplished many extravagant achievements in his lifetime. Descartes invented analytical geometry and established the foundation of skepticism as part of the scientific method. René Descartes’ contributions to the creation of the scientific method and his various books on metaphysics and reason allow him to stand out, but Descartes’ geometric theorems and theories on existence and truth are what made him one of the most influential and important philosopher and mathematicians in history.

     On the journey to find truth to base all thought upon, Descartes explains his first step in doing so. “Never accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgment than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.”(Kolak, Pg.228). Assuming that everything you see is fictitious, Descartes believed he had no senses at all; “body, shape, extension, motion, and place are unreal.”(Weissman, Pg.23). Our senses have failed us all at one point or another in our lives, so why use the senses as a base for thought? The most famous quote and philosophy by Descartes in history ever, “Je pense, donc je suis, cogito ergo sum” (Durant, Pg.639). “I think, therefore I am” was the first step towards a basis to understand truth, and leaning away from truth through the senses.

Descartes’ method of radical doubt focuses upon finding the truth about certain things from a philosophical perspective in order to truly lay down a foundation for ideas that have the slightest notion of doubt attached to them. He believed that there was “no greater task to perform in philosophy, than assiduously to seek out, once and for all, the best of all these arguments and to lay them out so precisely and plainly that henceforth all will take them to be true demonstrations” (Meditations, 36). The two key concepts that Descartes proves using the method of doubt are that the “human soul does not die with the body, and that God exists” as mentioned in his Letter of Dedication, since there are many that don’t believe the mentioned concepts because of the fact that they have not been proven or demonstrated. (Meditations, 35). In order to prove the above, he lays out six Meditations, each focusing on a different theme that leads us “to the knowledge of our mind and of God, so that of all things that can be known by the human mind, these latter are the most certain and the most evident” (Meditations, 40).

As the first “premise” of his proof Descartes makes a very important distinction between the various types of ideas. The first type of idea he discusses is ideas that are images of things. This type of idea, when thought of, is apprehended as an object of my thought, but there is something more embraced in the thought than merely the representation of the object. Now if these ideas are considered only in themselves, and are not referred to any object beyond them, they cannot, properly speaking, be false. This even applies to the will and affections, a second type of idea, for although I may desire objects that are wrong, it is still true that I desire them. The third type of idea is that of judgement. Descartes goal in this classification is to find in his mind which of the ideas are the proper bearers of truth and falsehood. Considered in themselves, ideas are not false nor are desires. The only place where mistakes can be made is in making judgements. As Descartes says, “And the chief and most common mistake which is to be found here consists in my judging that the ideas which are in me resemble, or conform to, things located outside me.” Descartes further classifies his ideas by their origin: those that appear

In Rene Descartes’ Discourse on Method he expresses his disappointment with traditional philosophy and with the limitations of theology; only logic, geometry and algebra hold his respect, because of the utter certainty which they can offer us. Unfortunately, because they depend on hypotheses, they cannot tell us what is real, i.e. what the world is really like. Therefore Descartes suggests a method of thought combining the consistency of mathematics but based on natural truths about what is real, basic knowledge which could not be wrong (like the axioms of geometry). He calls into question everything that he thinks he has learned through his senses but rests his entire system on the one truth that he cannot doubt, namely, the reality of his own mind and the radical difference between the mental and the physical aspects of the world.

However, the Meditator realizes that he is often convinced when he is dreaming that he is sensing real objects. He feels certain that he is awake and sitting by the fire, but reflects that often he has dreamed this very sort of thing and been thoroughly convinced by it. On further reflection, he realizes that even simple things can be doubted. Omnipotent God could make even our conception of mathematics false. One might argue that God is supremely good and would not lead Descartes to believe falsely all these things. He supposes that not God, but some "evil demon" has committed itself to deceiving him so that everything he thinks he knows is false. By doubting everything, he can at least be sure not to be misled into falsehood by this demon.

In the First Meditation, Descartes invites us to think skeptically. He entices us with familiar occasions of error, such as how the size of a distant tower can be mistaken. Next, an even more profound reflection on how dreams and reality are indistinguishable provides suitable justification to abandon all that he previously perceived as being truth. (18, 19) By discarding all familiarity and assumptions, Descartes hopes to eliminate all possible errors in locating new foundations of knowledge. An inescapable consequence of doubting senses and prior beliefs

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 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.

     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 his work Meditations on First Philosophy, published in 1641, René Descartes sets out to establish a set of indubitable truths for the sciences. He begins by discarding all of his beliefs, then works to rebuild his beliefs based on careful thought. Descartes clearly states this goal, saying in the First Meditation, “I will work my way up… I will accomplish this by putting aside everything that admits of the least doubt” (I, 17). He is able to establish his own existence, but struggles to move beyond his internal thoughts to discuss external objects. Descartes decides that the Christian God is the bridge he needs to escape the confines of his own mind, and argues for the existence of God in the Third Meditation in order to move on to discussing the physical world. In this paper I will argue that Descartes’ rationalistic project would have been improved without an appeal to the Christian God, although I will also argue that Descartes thinks this appeal is necessary.

First of all, Descartes’ cogito ergo sum rests on the method of doubt, and it’s only true because it appears to him as most clear and distinct, and thus cannot be doubted. He said that, “What of thinking? I find here that thought is an attribute that belongs to me; it alone cannot be separated from me” . So what Descartes is saying here seems to mean that thinking is a quality that he possesses, and that he cannot exist without having this quality, which means thinking is what justifies his being at this moment. He adds that, “I am, however, a real thing and really exist; but what thing? I have answered: a thing which thinks”. I take this to mean that the essence Descartes suggests here is him being a thinking thing. He is sure that he is a thinking thing because when he thinks that he is a thinking thing, it is impossible to say that he is not thinking, which is an attribute he claims to be a part of him in the beginning. The idea of this essence is pushed further in his wax

Rene Descartes was a philosopher of the 17th century. He had this keen interest in the search for certainty. For he was unimpressed with the way philosophy is during their time. He mused that nothing certain was coming forth from all the philosophical ideologies. He had considered that the case which philosophy was in was due to the fact that it was not grounded to something certain. He was primarily concerned with intellectual certainty, meaning that something that is certain through the intellect. Thus he was named a rationalist due to this the line of thought that he pursued. But in his work in the meditation, his method of finding this certainty was skeptical in nature; this is ‘the methodic doubt’.

Descartes first submits that it is not necessary to show all beliefs are false to satisfy the knowledge condition. He adds that if in each belief there is doubt that we can conclude that all things that we believe can be considered false knowledge. He seeks to prove this by setting a precondition that we cannot critique all beliefs, just the ones that govern our life or that serve as a broad component of belief. Descartes then provides context to where beliefs come from and states that beliefs are created from senses or through senses. He then states that senses are false because they are deceptive and shouldn’t be trusted which is the first cause of being able to doubt a belief. This idea in my opinion is the argument of Reality vs. Virtually, which is what we encounter through our experiences vs. what we dream about. The question posed is that we doubt our beliefs because we do not know if what we perceive from our senses is true. The example provided in the Meditations text dealt with imagination and the Dream world concept. If I perceive something in the
