Examples Of Cartesian Skepticism

There are three forms of doubts that Descartes believes in, one of which is the defective nature of doubt. The defective nature of doubt is reasonable because it gives Descartes a clean slate to begin doubting everything he’s uncertain of. Because Descartes wants knowledge and truth, he starts to look to doubt. To gain knowledge and truth one must have cautious perceptive that contains no doubt. Therefore, Descartes thinks that since the foundation of his knowledge had uncertain characteristics, he must take apart his knowledge and destroy everything he thought he knew. Then he starts to build his knowledge back up but only with things that he is certain of.

Clear your mind, if you will, of everything you have ever seen or known to be true. To begin understanding Rene Descartes’ method of doubt, you need to suspend all prejudice and prior judgments and start with a clean slate “for the purpose of discovering some ultimate truth on which to base all thought.” (Kolak, Pg.225). Discouraged with much skepticism from his own beliefs, Descartes was embarrassed of his own ignorance. He set out to try and accomplish the task of finding an absolute truth in which he would base his beliefs. Placing upon himself a task to find an axiom or absolute truth to base all thought, “he ventured as a youth in travel to collect a variety in experiences to derive some

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).

In the late 1500s to early 1600s, philosophy experience the revival of radical skepticism because of the ideology of Michel de Montaigne. Skeptics held that men cannot agree on anything, and it is almost impossible to understand if something is true, since everything can be an opinion or an interpretation (Lecture 2, 2016). However, a man named René Descartes was determined to disprove skepticism by using skepticism itself (Stewart, Blocker, & Petrik, 2013). To disprove skepticism, Descartes first doubted everything he had ever learned or believed until he discovered something that was ridiculous to doubt (Stewart, Blocker, & Petrik, 2013). Descartes resolved to doubt the core foundations upon which all of his belief rested upon: sense experience and intellectual intuition (Stewart, Blocker, & Petrik, 2013). External world skepticism was one area that lead Descartes to write his famous essays, titled Meditations, and this topic

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.

An approached by Rene Descartes Methodological doubt is skepticism in an approached that question the possibility of certain knowledge. Humans can only believe that they are awake, there is no way to distinguish if we are experiencing a dream or that we are awake. For example, if I see my friend playing basketball there is a lot of evidence that exist to indicate it is reality but there is also evidence to conclude that we are in a dream as well. We can use our senses which are; sight, hearing, smell, taste, and touch to determine what is real. Descartes believes that knowledge comes from our senses, so I can use my senses to determine that my friend is indeed playing basketball. My senses can also be fooled and have me think that my friend is not in fact playing basketball and it’s just a projection of my subconscious mind.

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.

Skepticism is define as an intellectual process of applying reason and critical thinking to validate a certain point. Skepticism was the very base for Descartes arguments in the first two meditations. He started by

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".

     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 believes that knowledge comes from within the mind. This is a single indisputable fact to build on that can be gained through individual reflection. While seeking true knowledge, Descartes writes his Six Meditations. In these meditations, Descartes tries to develop a strong foundation, which all knowledge can be built upon. In the First Meditation, Descartes begins developing this foundation through the method of doubt. He casts doubt upon all his previous beliefs, including “matters which are not entirely certain and indubitable [and] those which appear to be manifestly false.” (Descartes, p.75, par.3) Once Descartes clears away all beliefs that can be called into doubt, he can then build a strong base for all true

Descartes’s theory of knowledge is essentially based in skepticism. He argued that in order to understand the world, first a person has to completely suspend their judgements of the world around them. This is the impression that the world makes on their mind. In this way, the physical world is not what leads to knowledge. Instead, the mind finds rationally seeks knowledge. The question is, essentially, “should we believe beyond the evidence?” (Kessler, 2013, p. 332). In this way, the ideas are rooted in the nature of doubt. This is an inherent nature of the mind, which is the result of the nature of man as made by God. In this way, the mind is guided by god towards knowledge in its infallible ability to reason about reality. In this way, the mind’s reasoning ability, even in the absence of physical reality, can ultimately lead to knowledge. I don’t fully agree with Descartes’ proposition that only the mind can produce certain knowledge and that our senses are constantly under the attack and being deceive by some evil deceiver. In order to go against Descartes propositions concerning about doubt I will use Locke to oppose it.

Ultimately, Descartes' "radical doubt" challenges how we look at the mind and how it represents us with information and knowledge. He uses his radical doubt theory to explain how the information that we receive through our senses is distorted and can not be utilized as a means of knowledge. Essentially, Descartes is questioning reality and the risk of deception that it poses in the process of acquiring knowledge. Although Descartes makes a valid argument in regards to the nature of reality, there is a huge discrepancy with his theory of "radical doubt" in regards to epistemology; how can there be a question of reality at all when all knowledge is, according to rationalists, innate?

Skepticism in general says that we do not know many propositions about the external world that we naturally take ourselves to know. Descartes affirms skepticism by analyzing beliefs as knowledge. Meditations seeks to find a solution to the notion of if one doubts a belief, can it be considered knowledge?

In the first of Rene Descartes Meditations, he provided arguments for the skeptical position. He
