Rene Descartes Deceit

In “Bad Dreams, Evil Demons, and the Experience Machine: Philosophy and the Matrix”, Christopher Grau explains Rene Descartes argument in Meditation. What one may interpret as reality may not be more than a figment of one’s imagination. One argument that Grau points out in Descartes essay is how one knows that what one think is an everyday experience awake is not all a part of a hallucination. He uses the example of dreams to draw a conclusion about is claim based on experiences one would experience with dreaming. He asserts that there are times when one wake up from a dream that seems to be “vivid and realistic” however soon finds that it was not. The experience of reality in the dream was all a part of the mind. If dreams seem to be

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

To know anything about the external world on the basis or your sensory experiences, you have to know that you are not dreaming.

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.

In his First Meditation (Feinberg & Shafer-Landau, 2001) Descartes explored his ideas regarding knowledge and skepticism, which led to him developing ideas based around the certainty of his experiences. From this he developed his first argument: the dreaming argument.

It is deception from the sense that causes this mistrust for Descartes and brings forth the Dream Argument. The human senses as well feel very real, just as they do in reality, and this is one of the first things that have Descartes question the differences between being awake and dream. Due to the trust issues it he becomes unsure of whether he is dreaming or not. When it comes to dreaming Descartes thinks that there could possibility that some certain God that may have easily deceived him in falsely believing in things could appear to be correct but are not. However Descartes says that it God is described as a supremely good being (Descartes, 21). God has always been a being that is worshiped and why would so many people worship an evil God if he brings no positives to their lives. Descartes however is not 100 percent positive on whether God is being deceptive or not being deceptive. James Hill says that “[the] key move that Descartes then makes is to highlight the lack of insight one has into one’s condition when dreaming. It is this lack of insight, and Descartes’ way of interpreting it, which forms the backbone of the dreaming argument” (Hill, 2). To shorten that down, the minimal explanations to why and how dreams occur is the foundation for Descartes’s Dream 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

Meaning, we could be constantly dreaming and not be aware of it. He uses this line of reasoning to support his claim that sense and perception can not be trusted and that nothing is certain. Descartes mentions being able to have perceptions similar to the sensations he has while dreaming. Therefore there are no definitive signs of to discern between dream experience and wake experience. Which makes it possible for him to claim that he may be dreaming at that very moment, even though he may think he is meditating or writing, it is all a sensory and perceptive illusion. Backing his statement with the concept of doubt and skepticism, he is able to fully explain why one can not tell whether they are awake of dreaming. Consequently, we must carefully test and examine our senses to determine if they represent

Descartes knows that his images of everything are built upon his senses. When Descartes is dreaming, he dream of things that seem to be real. Descartes last skeptical argument was about deceiving God. We are told that there is a powerful God who has created us and who has all the powers to control anything and everything. Descartes says that we rely on our senses to determine what is mostly true and many of the decisions we make are based on our senses and feelings.

Because our senses come into practice when dreaming takes place, Descartes mentions how humans have the tendency to think it is reality when they are in fact dreaming. He uses a simple story to prove this, by saying how he could be sitting by the fireside and feeling its warmth while dreaming in bed in his nightgown. Our senses fool us because in this dream, we believe it is reality. On the other hand, I disagree with Descartes that senses are false in reality. Dreaming and reality are two completely different worlds, and I do not believe that are senses can fool us into thinking we are dreaming.

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

He finds it plausible that we are all living in a dream and we have never experienced reality. He can no longer give any credence to his senses and finds himself in a place of complete uncertainty. Descartes comes to the conclusion that nothing can be perceived more easily and more evidently than his own mind. He has discovered that even bodies are not accurately perceived by the senses or the faculty of imagination, and are only accurately being perceived by the intellect. He also realizes that they are not distinguished through being touched, smelled, or tasted, but by being understood alone. (An apple is an apple because our mind tells us that it is an apple.) It is the faculty of reason that gives the knowledge and lets the mind know the truths and essences of objects. Descartes assumes that all of us can be decided by our senses, someone can see something far away, and then discover that is not what we thought it was. Or even a oar when is immerse half in water attempt to be bent, but instead is straight. Descartes think that we cannot always be sure of what we sense, and gives the example of himself seated by the fire.

This argument is based in the uncertainty of knowledge. Descartes argues that we cannot be certain of the physical impressions upon our minds because the world can potentially deceive the mind, leaving it with false impressions. Due to the fact that our minds can conceive of a reality in which we are dreaming or some nefarious force is
