The Dreaming Argument And The Evil Demon Argument

Grau manifests that we cannot justify any of our beliefs to be true if, in fact, the possibility that we may always be dreaming is true. Using Descartes personal experience with dreams, about how he often wakes up at night thinking he was at one place when he was actually laying undressed in bed, Grau develops plausible reasoning for not being able to rule out the possibility that we are always dreaming. Grau asserts that there are times when one wakes up from a dream that often seems as vivid and “realistic” as real life, however, soon after we will find that it is not. Therefore, we find that our experiences of reality in our dreams are just components of our mind. Descartes example of dreams establishes that we cannot trust what we are experiencing to actually be real. How can we prove that we are awake other than

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

Descartes first presents this idea with the statement "How often does my evening slumber persuade me of such ordinary things as these: that I am here, clothed in my dressing gown, seated next to the fireplace -- when in fact I am lying undressed in bed!" (Descartes 490). By using an experience of his own, Descartes shows how dreams can be asymptotic to reality. Descartes implies that he often sits next to his fireplace, clothed in his dressing gown, so his dream that he is doing so is very believable. In conclusion, one cannot distinguish between a dream and reality because the gradient between them is so finitely small at times.

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

In this essay, I will explore and analyse Descartes’ dreaming argument and his evil demon argument. I will assess both arguments taking into account their validity and soundness whilst also considering the objections that one may have.

    The Dream Argument states that because we are unable to eliminate the possibility that we are dreaming our perceived reality, we cannot know anything about it. Formally, we can express this as:

The Dreaming argument first showed up in Descartes First Meditation, where he focusses on the task to educate himself on his own doubt. When meditating he starts to think about how he has a hard time distinguishing himself from being asleep and awaking. This is how the dreaming argument came forth. The Dreaming Argument easily said is “If I am certain of anything, then I have to be certain that

Descartes’ initial dream argument is weak and proves to not hold up against his other skeptical hypotheses.

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

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.

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.

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

According to Descartes’, “As I think about this more carefully, I see plainly that there are never any sure signs by means of which being awake can be distinguished from being asleep.” This is the fundamental principle of the Dreaming Argument. The scenarios in which we experience whilst we are asleep are comparable to the scenarios we experience whilst we are awake. Often, we struggle to tell from our own perspective where our experiences are derived from; it is difficult to differentiate whether our experiences stem from reality or our dreams. The issue with this is that our unconscious

Descartes dreaming argument suggests that perhaps our senses cannot be fully trusted because we cannot be certain we are not dreaming, and this means we therefore cannot be certain of anything. His evil demon argument is similar but uses the idea of an evil demon deceiving you instead of your senses. These sceptical arguments mean that we cannot be certain of anything at all for it may be happening whilst we are dreaming, or we are being tricked into thinking it is happening. I do not agree with Descartes because I feel that I can be certain I am not dreaming, and I do not believe that other supernatural creatures; such as an evil demon exists.
