Certainty Of Rene Descartes

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.

René Descartes was the first philosopher to raise the question of how we can claim to know anything about the world with certainty. The idea is not that these doubts are probable, but that their possibility can never be entirely ruled out. If we can never be certain, how can we claim to know anything?

René Descartes was a skeptic, and thus he believed that in order for something to be considered a true piece of knowledge, that “knowledge must have a certain stability,” (Cottingham 21). In his work, Meditations on First Philosophy, Descartes concludes that in order to achieve this stability, he must start at the foundations for all of his opinions and find the basis of doubt in each of them. David Hume, however, holds a different position on skepticism in his work An Enquiry concerning Human Understanding, for he criticizes Descartes’ claim because “‘it is impossible,’” (qtd. in Cottingham 35). Both philosophers show distinct reasoning in what skepticism is and how it is useful in finding stability.

His cogito is a clear and distinct idea that it is true after all. Descartes doesn’t mean for people to take this arguments literally, but rather a way to demonstrate that our senses may be altered or deceived.

Descartes answers his seemingly hopeless skepticism from the first meditation with the Cogito. The basic point of his Cogito argument is that for me to either perceive awry, or even to doubt my own existence, I must exist. It is, as Descartes says, “’I am, I exist’ is necessarily true every time it is uttered by me or conceived in my mind (Med2, par3).” He makes two arguments for the Cogito in his second meditation. Descartes arrives at the Cogito through the notion of an omnipotent deceiver actually. He starts to question his own

The skeptical argument of Descartes opens with how he reflects on several lies that he has believed throughout his life and on the following faultiness of the body of knowledge he has made up from these lies. He has decided to sweep all he thought that he knew so as to begin again from the foundations, to be able to build up his knowledge once again and on more sure grounds. In order to display that science rested on sure strong foundations and that these foundations lay in the mind and not the sense, he began by carrying into doubt all the principles that come to us from the senses. His intention in these arguments is not categorically to prove that there is none that exists or that it is unmanageable for the people to known if anything exists,

     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

Descartes' meditations are created in pursuit of certainty, or true knowledge. He cannot assume that what he has learned is necessarily true, because he is unsure of the accuracy of its initial source. In order to purge himself of all information that is possibly wrong, he subjects his knowledge to methodic doubt. This results in a (theoretical) doubt of everything he knows. Anything, he reasons, that can sustain such serious doubt must be unquestionable truth, and knowledge can then be built from that base. Eventually, Descartes doubts everything. But by doubting, he must exist, hence his "Cogito ergo sum".

The cogito concept stands regardless of empirical knowledge because it suggests the existence of thought without actually linking it to the body (which constitutes a sort of empirical way of acquiring knowledge through the senses). In addition, it can be accepted without any a priori knowledge since Descartes only introduced it after concluding that he knew nothing, and could only accept knowledge of his own existence as vindicated.

In his first meditation, Descartes sets out with amazing clarity and persistence to clear himself of every false idea that he has acquired previous to this, and determine what he truly knows. To rid him of these "rotten apples" he has developed a method of doubt with a goal to construct a set of beliefs on foundations which are indubitable. On these foundations, Descartes applies three levels of skepticism, which in turn, generate three levels at which our thoughts may be deceived by error. Descartes states quite explicitly in the synopsis, that we can doubt all things which are material as long as "we have no foundations for the sciences other than those which we have had up till now"(synopsis:12). This

Descartes accepted that we ought to never acknowledge anything about which we can entertain any doubt. So in his attempt to discover scholarly sureness, Descartes occupied with a procedure of precise uncertainty, in which he started doubting everything until he could locate the one thing that couldn't be doubted. As we see from the story, Descartes comes to the certainty that one thing that he cannot doubt is that he is a thing that thinks which includes doubt, understands, affirms, denies, wills, and refuses. Because it is clear that I exist in the event that I question that I exist. My uncertainty that I exist demonstrates that I exist, for I need to exist to have the capacity to doubt. Subsequently I can't doubt that I exist. Consequently,

Rene Descartes was a French philosopher in the 17th century who flirted with the idea that everything that in the world was false. The concept of everything being somewhat unreliable with no real certainty attached is the basis of skepticism. Throughout his studies, Descartes introduced an idea that helped justify his argument of everything being fake. This idea is that there may be an all powerful evil being whose goal is to deceive one from reality.

The cogito, “I think” is Descartes’ first certainty and his first step into knowledge. Descartes argues that there is one thing that he is most certain of and even the evil demon can manipulate and make him doubt. He cannot doubt that he thinks because even doubting of a form of thinking and that means that he will be thinking. Even if the demon made him doubt that he is thinking, he would be confident that he is thinking that the demon is making him doubt his thinking. He cannot also doubt that he exists and if he were to doubt of his existence, he would prove that he exists because of his thoughts, and thus his thinking means he exists and hence if he exists then he must be thinking of his existence. Therefore, Descartes extends his certainty

First lets look at its strengths. In my opinion, the primary strength of Descartes argument lies in the fact that he claims the certainty of his own existence only. He utilizes a first person point of view throughout the meditations in order to exemplify the fact that he is not trying to prove the existence of others. This view of thinking is easily applicable to our own lives. This form of thought allowed Descartes to further his foundationalism whilst still maintaining his skepticism. Descartes acknowledged that this argument on its own proved very little and was open to questioning; yet it still provided a backdrop for the rest of his argument. Yet the Cogito is still not beyond all doubt. Just because Descartes has proven that thoughts exist does not necessarily mean that he exists. we could argue that merely thinking does not guarantee that ‘I’ exist, and therefore the cogito is not beyond all doubt. Descartes reject common definitions such as man, instead referring to simply “a thing.” Descartes concludes his

During Meditations 2, Descartes establishes a version of his famous ‘cogito ergo sum’. He establishes that despite the fact that we may not know the world around us as well as we think we do, we can know the mind better and the trusting the mind can lead him to the seemingly justified conclusion that he exists.
