Descartes Matrix Of Illusion

In Descartes’ First Meditation, Descartes’ overall intention is to present the idea that our perceptions and sensations are flawed and should not be trusted entirely. His purpose is to create the greatest possible doubt of our senses. To convey this thought, Descartes has three main arguments in the First Meditation: The dream argument, the deceiving God argument, and the evil demon “or evil genius”. Descartes’ dream argument argues that there is no definite transition from a dream to reality, and since dreams are so close to reality, one can never really determine whether they are dreaming

Descartes’ Dreaming Argument comes from his thinking that there is no way of knowing if you are sleeping or if you are awake. To know something is to have no doubt of a fact, it must be a justified true belief. To be justified it must hold logical reason, you cannot state something is true without evidence. In order for it to be true it is not enough to justify it, but it must be justified with true facts. Finally, you must believe it, in order to know something it must be true in your mind. As a result Descartes doubts his consciousness as he cannot truly know that he is awake. This spurs Descartes to question if any perceived knowledge of reality is really true. Descartes calls his senses into questions as he notes, “it is prudent never to trust completely those who have deceived us even once” and therefore concludes that as a result it is prudent, never to trust his sense. In

     The second argument that Descartes defends is another question posed towards the senses. How can we take anything as real if our dreams cannot be

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 organised his ideas on knowledge and skepticism to establish two main arguments, the dreaming argument and the evil demon argument. The dreaming argument suggests that it is not possible to distinguish between having a waking experience and dreaming an experience. Whereas, the evil demon argument suggests that we are deceived in all areas of our experiences by an evil demon. This essay will investigate the validity of the arguments and to what extent the conclusion of these arguments is true. The soundness and the extent to which the premises are true will also be explored. After evaluating these arguments it will be concluded that the dreaming argument is valid, but is not sound. Whereas, the evil demon argument is both valid and sound.

In the fifth and last skeptical hypothesis, Descartes raises the possibility of there being an evil demon that deceives him into believing falsehoods. Descartes has established arguments that either support or demolish the thoughts for all of these skeptical hypotheses. As stated previously, the dream argument points out that people may actually be dreaming when they think they are living in reality. Descartes used his methods of detecting falsities to evaluate this argument.

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).

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.

Dream Skepticism has been debated largely since Descartes’ projection of those ideas. Descartes believed many irrational thoughts in relation to dreaming, which proposed ideas that nobody at his time had ever seen before. Descartes’ challenging of the traditional ideas and proposing new ones in which challenged the minds of the individuals, as well as trying to convince the masses that dreaming had some sort of value for an individual that would carry on into his conscious world. Throughout these different ideas lied his main notion: the dreams produced in the human brain while unconscious are not false or fiction, rather, they present the truths that lie in our very minds and therefor should hold value to the dreamer himself. Descartes believed

The argument Descartes brings up is can we trust our senses enough to tell what is real and what is fake. Descartes brings up if things seems so real such as when he is writing “I am here, sitting by the fire, wearing a dressing-gown, with papers in hand…” (p. 292)1.

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

Once Descartes established himself as a "thinking thing", his attention turns to the external world. Descartes reflects upon his dealing with physical objects, and questions the state of physical nature, dealing directly with the senses. Restating the fact that Descartes believes that these sensations of taste, touch, smell, and the like can be fooled, he attacks these bodily perceptions, not from the point of "what makes them true", but rather "what makes them false". These senses lead him to ideas of external objects, which he claims to perceive clearly and distinctly, yet he is not

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

The concept of Descartes’ meditation is an interesting one. He admits that he was living a lie, has been mistaken, and wants to discard his previous perceptions and thoughts and start afresh living a life he considers certain. He thinks that in his life he could be dreaming, and his senses are deceiving him to believe in things that are uncertain. However, even if he no longer wants to trust his senses, one thing is certain, he must be living or existing. Having the capability to doubt of the pre-conceptions proves to him that he is thinking, and something thinking and planning is currently in existence. His aim here is not to show everything that we see does not exist, or we human are incapable of knowing whether they exist or not. The aim is to prove that human knowledge on these things based on the senses is open to questions and doubt. The implication of this perception is that since we are certain that external things exist, it is impossible for humans to have this knowledge through the senses, but rather the mind.
