On Meditation 1, the philosopher Rene Descartes centers on the idea that senses can not be trusted. Since in the past senses deceived him and let to false beliefs. Therefore his main concern is to erase all of the false beliefs he held to be true by analyzing and questioning which of them should be unreliable. Descartes, then, creates a new belief system in which all of the beliefs are correct.
By doing this, he eliminates the doubt by arguing the possibility of an evil demon that is capable of deceiving our senses and even the mathematical knowledge we might have. That is, maybe this evil demon manipulates my thoughts so I can see only what he wants me to see. It is like that the only existent things in the world are the evil demon and I. Nothing else around me exists. But can I question things not perceived by the senses? Is it possible to doubt that a square has four sides and 1+1=2? The answer would be yes. This evil demon can put this into my mind so I can see it. Thus, I do not have any mathematical knowledge. If this is the case, then I should not trust anything that comes from my senses and reasons. Therefore, nothing based upon sense experience can count as certain.
Another skeptical argument Descartes present in meditation 1 is whether or not we can distinguish dreams from reality. In this argument, Descartes is saying that when I dream I have similar sense experience as to when I am awake. However, those experiences are not precisely accurate as to
Although Descartes argument seems plausible decades ago, now there are ways to weaken is argument. In the science of psychology which focuses on the brain one can find that there are ways of knowing one is dreaming or sleep. Descartes even contradicts himself when he asserts “that even if all of our sensory experience is but a dream, we can still conclude that we have some knowledge of the nature of reality”. I believe that Descartes knows that he is not dreaming in a constant state of dream but that there is a sense of reality that one experiences. What one experiences are senses such as smell and touch that one cannot perform in a dream world. Being able to touch and have the sensation of touching an item such as a table in a dream does not happen. The sensation of pain is also an indicator of a reality that does not exist in the reaffirms that one is not in reality.
The Method of Doubt is destructive, not constructive, and aims to destroy and rebuild our knowledge on firm foundations. Once Descartes used the Evil Demon Hypothesis, he was able to remove all prior beliefs which left him with a starting point from where he could rebuild all true knowledge. The hypothesis doesn’t try to prove the existence of the Evil Demon, but rather to prove scepticism of our senses and even our understanding of the simplest concepts like maths and science is correctly placed (SparkNotes Editors, n.d.). Some critics described the hypothesis as a counterweight our ‘habitual beliefs’ (Cottingham, 1976:261). The argument is such a hyperbolic assumption that it puts even our strongest beliefs into doubt. Professor Harry Frankfurt gave an alternative view on the function of the demon. According to him, one role of the demon is to raise the possibility that we make errors in mathematical judgement. More significantly he believed the Evil Demon Hypothesis tried to falsify mathematical knowledge by ‘casting doubt on the objects of mathematics’ (Cottingham, 1976:263). However I believe that the demon’s importance on mathematics is more of a side track from the First Meditations main idea and the main role of the demon is to raise doubts about the external world. By the end of the First Meditation, Descartes had reached a point of total deception. He cannot be sure of what he experiences
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
This is Descartes’ Evil Demon argument. These two arguments are important as they bring up many queries about how we live our lives, and if we can really be certain of anything around us at all.
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
How do we know we are not dreaming some particular experience we are having, or we are not dreaming all our experience of this world? When we dream we imagine things happening often with the same sense of reality as we do when we are awake. In Descartes dream argument, he states there are no reliable signs distinguishing sleeping from waking. In his dream argument, he is not saying we are merely dreaming all of what we experience, nor, is he saying we can distinguish dreaming from being awake. I think his point is we cannot be for sure what we experience as being real in this world is actually real.
While it can be said that premise 1 is true, many people disagree strongly with premise 2. Descartes claims that we cannot be certain that we are not dreaming, but our dreaming experiences and our waking experiences are dissimilar. Our dreams often do not make sense and do not fit into a consistent and comprehensible timeline of events unlike our waking experiences. Even in circumstances where dreams are vivid and seem real for a short period of time, we are able to recall these dreams and acknowledge that they were not real life events. On the other hand, this view can be challenged by recognising we appear to be awake when we think about our dreams, but Descartes objective is to make the reader consider if it is possible that even the process of waking and reflecting upon a dream is part of the dream itself, thus reinforcing the idea that we are unable to differentiate between dreaming and being awake. The final limitation of this argument that I would like to discuss within this essay is its paradoxical nature. Although the premises of this argument appear reasonable, the conclusion seems ridiculous. While the conclusion does follow from the premises, creating a valid argument, the conclusion remains arguably unacceptable.
The dreaming argument was based upon the idea that both waking and sleeping (dreaming) experiences can be very similar, and that distinguishing between the two may not be possible. This led to Descartes doubting that waking experiences are actually infact waking experiences and not dreams. Descartes developed this argument and claimed that in order to be certain of any experiences, we have to be certain that we are not dreaming. However, Descartes continued and
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.
One of Rene Descartes’s most famous arguments, from his not only from his first meditation but all of the meditations, is his Dream Argument. Descartes believes that there is no way to be able to distinguish being in awake from being in a state of dreaming. In fact you could actually be in a dream right now. Rene Descartes’s theory that one is unable distinguish being awake from dreaming, as interesting as it is, can be at times a little farfetched, along with a few contradictions to himself, Descartes’s dream argument does not entitle himself to any sort of claim.
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.
However, the Meditator realizes that he is often convinced when he is dreaming that he is sensing real objects. He feels certain that he is awake and sitting by the fire, but reflects that often he has dreamed this very sort of thing and been thoroughly convinced by it. On further reflection, he realizes that even simple things can be doubted. Omnipotent God could make even our conception of mathematics false. One might argue that God is supremely good and would not lead Descartes to believe falsely all these things. He supposes that not God, but some "evil demon" has committed itself to deceiving him so that everything he thinks he knows is false. By doubting everything, he can at least be sure not to be misled into falsehood by this demon.
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
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
The whole point of this method is for Descartes to find at least some truth that is way beyond any questions of doubt. However, what if people doubt that the two plus two does not equal to four but in reality of our minds, we all can conclude that is equals to four. After this point, Descartes introduces the idea of a “malicious god” or “evil demon” who’s only goal is to deceive us no matter what, Descartes says, “I will suppose, then, not that there is a supremely good God who is the source of all truth, but that there is an evil demon, supremely powerful and cunning, who works as hard as he can to deceive me” (Descartes 322.Right Side). Although we all know that two plus two equals four but what if the evil demon is deceiving us and in reality, it equals five. These three stages make up Descartes methodic doubt, where he attempts to remove all previous beliefs in order to find truth that is beyond any
