How Does Descartes Find Something He Cannot Doubt

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

In order to weigh up these arguments, it is important to understand Descartes’ reasons for formulating them: Descartes’ believes that it is important to be certain of the things that one believes to be true which, in turn, causes him to question the things that he has been certain of thus far. Because of this, he forms these arguments to further consider his theories about doubt and what it is to be truly certain of anything.

Descartes’ skeptical arguments begin from the thought that everything can be doubted; the first being our senses. He claims that our senses can sometimes deceive us (e.g. when viewing things from far away). Things that can deceive us once, have the possibility to be deceiving us all the time—giving us reason to doubt all sensory claims. This leads to a problem since humans rely on empirical knowledge. If one cannot consider any claim delivered by sense to be true knowledge, then it gives reason for one to doubt reality. Following is the dream argument in which what seems to be tangible reality, is an effect of a dreaming experience. Descartes gives the example of dreaming he is sitting by a fire when in actuality he could be asleep

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).

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?

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.

In the first meditation, "Concerning those things that can be called into doubt", Descartes main goal is to distinguish what it is he can take to be true, and what supposed truths hold even the smallest degree of doubt. When he reviews all of his opinions he concludes "eventually [he] is forced to admit that there is nothing among the things [he]believed to be true which it is not permissable to doubt--and not out of frivolity or lack of forethought, but for valid and considered reasons. Thus [he] must be no less careful to withhold assent henceforth even from these beliefs then [he] would from those that are patently false, if [he wishes] to find anything certain."(Pg62) At the beginning of Descartes' meditations, he finds that there is really no concrete pillars of knowledge to base the foundations of his supposed

In Descartes, What Can Be Called to Doubt, he discusses whether or not everything around us is real, or fake. He believes that there are opinions we form that are false, but we fail to realize it. So, by questioning each belief, one could then find the truth in what we believe. He also states that most of our beliefs we get from using our senses. Then he questions our senses in the context of dreaming. When dreaming you cant tell if you are awake or not. At this moment you could be dreaming and there would be no way to prove or disprove that. Descartes then brings God into the picture saying, "How do I know that he hasn’t brought it about that there is no earth, no sky, nothing that takes up space, no shape, no size, no place, while making

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).

Descartes defines senses as a part of the process of thinking. He also explains that we can use our senses to help us understand the true nature of things. Descartes struggled with doubt and his senses when he used his ontological proof that God existed. For example, he explains that he is aware that he is not perfect and he makes mistakes. He understands that he must know what perfect is in order to give someone the title. He knew that something perfect lead him to have these ideas and that it must exist. His definition of perfect is unique without the knowledge of anyone else and he defined it as God. For example, Descartes believes that God is perfect and deception is a sign of imperfection. Therefore, Descartes came to the conclusion that God cannot deceive. This example shows that Descartes did struggle to accept his own belief without doubting himself. His ontological argument proved, to Descartes, that through God everything

In Descartes' book, Meditations on First Philosophy, he explains the skeptical arguments of how he view doubt. Descartes' doubt comes in three waves, which makes it easy for him to determine what he can doubt but difficult to restore faith back into his senses' reliability. The first wave of doubt is dreaming, in which he argues that all of the particulars are merely illusions. The second wave of doubt is the simplest facts remaining real. Descartes knows that there are things that will always just be true forever and that they are simplest facts, like geometry, and things that may contain more complexity, like physics. The third wave of doubt is the deceiving deity, in which a deceiving demon is controlling his senses at times. Through these

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 a very bright mathematicain and considered to be the founder of modern philsophy didn't always start out as skeptic he believed that there was a point for everything that we may know until he realized that we tend to be decieved by our own senses which makes them an untrustworthy source. However some things that we precieve to be true are so evident that they must be true Descartes eventually arrvies at his concept of self after initial skepticism he begins with "cogito ergo sum" which means "I think therefore I am". However Descartes came to a conclusion that he cannot be wrong of his exsistence because if he is able to doubt therefore he must exist he believes that he can doubt anything and be decitful about the existence of other

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".
