René Descartes Evil Demon Argument

In the First Meditation, Descartes gives us the Evil Demon Hypothesis which serves to give him reason to doubt the existence of everything he perceives and believes. He describes a ‘malicious demon of the utmost power and cunning’ that has the sole purpose of deceiving Descartes (Descartes, 2010: 17). I will argue that his hypothesis has proven to be a strong one because only the cogito provides a way for us to frustrate or trick the evil demon.

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

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’ 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).

Rene Descartes argues that a rational method is required to have knowledge. Descartes wants to determine which, if any beliefs, he has that are certain must be true! He employs a method of doubt whereby he hopes to find at least one foundational belief. The Evil Demon suggests that all of one’s experiences might be the result of a powerful outside force, a “Malicious demon”. Descartes had 3 types of beliefs: Beliefs about the world- Optical illusions, Beliefs about self- Dreaming and Beliefs about Math/Science- Evil Demon. He employs a method of doubt whereby he arrives at his one foundational belief. The evil demon can trick you into belief. According to Descartes a being cannot have knowledge of a being higher of the scale, unless the higher being imparts that knowledge to him. His limited intellect could never hope to comprehend God unless God imparted the Knowledge. Since Descartes has a clear and distinct notion of God, God must exist. Since God exists and all is good, all of Descartes previous doubts were washed away. God would not allow an evil being to deceive us.

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.

Descartes also finds that anything that exists physically is false, even including his own body. The only things we should trust are those beliefs that can be held up to rational scrutiny. Thus Descartes doubts everything but himself, he feels himself is the only thing in this life which cannot be proven false. He states that if he had no knowledge of himself than nothing can be certain. If he himself can doubt than he must exist and in cannot be proven false. Another proof that he exists is that in order to be deceived one must be able to exist. Descartes states in his famous quote, "I think, therefore I am."

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

René Descartes was born in a village near Tours in France in 1596. At the age of eight years, he entered the Jesuit College La Flèche in Anjou, where he would study classics, logic, and Aristotelian philosophy, as well as mathematics from the books of Clavius. He is also known as the “Father of Modern Philosophy”.

René Descartes was an extremely influential 17th-century philosopher and came up with many ideas that still persist to this day. One of those ideas was Cartesian skepticism, which states that “the view that we do not or cannot have knowledge in regard to a particular domain,” knowledge, in this case, is justified, true, beliefs. He first comes up with his idea of skepticism in the first part of his work “Meditations On First Philosophy,” aptly named “Of the things which may be brought within the sphere of the doubtful.” In his first meditation, he discusses his doubts with sensory illusion/error, possible dream states, and regarding deception by an evil demon. However, after dissolving his first two doubts, he gets stuck on the third and

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’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.
