In addition, due to dreams mainly consisting of objects and events, Descartes believed that there is no reason to doubt general beliefs as much as physical objects as 3+2 still equals 5, and a square will always have four sides (14). As a result of this, Descartes concluded that there is a degree of truth in objects we sense as those concepts must have come from somewhere,
Descartes then attempts to define what he is. He previously believed that he had a spirit and body, by methods for which he was fed, moved, could sense, absorb space, had a distinct area and think. Each one of those methods are thrown into uncertainty except thinking. Since he can think, he should exist. He thinks about whether he no longer exists once his reasoning comes to a halt.
Dreams are defined as a series of images, ideas, emotions, and sensations that occur involuntarily in the mind during sleep. Psychological studies show that dreams only occur during certain stages of sleep. However, Rene Descartes, a French philosopher argues that the sensations felt in dreams are indistinguishable from the ones we feel in real life. In Descartes Meditations I, Descartes talks about the dream argument in which he introduces the following premises. 1.
Notre Dame ID: 902008117 In René Descartes ' Mediations on First Philosophy, Descartes abandons all previous notions or things that he holds to be true and attempts to reason through his beliefs to find the things that he can truly know without a doubt. In his first two meditations Descartes comes to the conclusion that all that he can truly know is that he exists, and that he is a thinking being. In his third meditation, Descartes concludes that he came to know his existence, and the fact that he is a thinking being, from his clear and distinct perception of these two facts. Descartes then argues that if his clear and distinct perception would turn out to be false, then his clear and distinct perception that he was a thinking being would not have been enough to make him certain of it (Blanchette).
However, Descartes could not without a doubt solely discard his perceptions based on his senses, just because his senses did or did not fail him on other occasions or under less than ideal circumstances. This argument does not allow Descartes to doubt all that could be doubted. The dream argument is a skeptical argument. It means is that it is possible, at any given moment, one could be sleeping and having only dreams, but the dreams are so realistic that they are undistinguishable from sleep or waking experiences.
“How do I know that I am not dreaming” is one of the main questions that Descartes brings afloat in the dream argument. He wants to know how can it be possible to prove that he is not dreaming while he is seating and holding his piece of paper, and this is what creates a skeptic argument about his perceptual beliefs. In effect, the dream argument is powerful because it depicts how the senses may deceive us while putting into question if it is possible to know what is real and what is not. In fact, it is very sufficient to produce uncertainties about waking experiences. As Descartes poses it in the in the First Meditation, “…I dreamt that I found myself in this particular place, that I was dressed and seated near the fire, whilst in reality
Descartes declares he has to determine if there is a God and if he does exist, whether he can be a deceiver. The reason he has to determine the existence of God and what he is, rests in his theories of ideas. This is because we do not know if there is an outside world and we can almost imagine everything, so all depends on God’s existence and if he is a deceiver. “To prove that this non-deceiving God exists, Descartes finds in his mind a few principles he regards as necessary truths which are evident by the “natural light” which is the power or cognitive faculty for clear and distinct perception.” If arguments is presented in logical trains of thought, people could not help but to be swayed and to understand those arguments.
In this paper, I will deliver a reconstruction of Descartes’ Cogito Argument and my reasoning to validate it as indubitable. I will do so by justifying my interpretations through valid arguments and claim, by showcasing examples with reasoning. Rene Descartes is a French Philosopher of the 17th century, who formulated the philosophical Cogito argument by the name of ‘cogito ergo sum,’ also known as “I think, therefore, I am.” Rene was a skeptic philosopher amongst many scholastic philosophers of his time. To interpret his cogito argument as indubitable and whether it could serve as a foundational belief, he took a skeptical approach towards the relations between thoughts and existence.
In that respect I compare this with the Matrix by stating the humans in the Matrix thought that they were awake, but it was a type of sleep because it was all an illusion and as I’ve stated prior, they were living a virtual life, and that is not real. Descartes goes on to talk about the “malignant demon” and question if all “external things” are basically “nothing better than the illusions of dreams” and that the demon has deceived him. When he seems to resolve that he will stay in his “slumber” he is stating the same thing that Cypher did in the Matrix. Cypher believed that “knowing the truth would make life easier” but he found out that for him he liked being controlled by the computer and wanted to “erase his memories of the truth.” So he wanted to stay in an illusion or a
The idea that if one can comprehend something in a dream, it therefore must exist in real life. The fact of this is that we know no positive transition between our dream state and the state of reality, and since dreams are so similar to reality, one can never tell when they are truly dreaming. Descartes demonstrates this idea with his own experiences, “How often, asleep at night, am I convinced of just such familiar events-that I am here in my dressing-gown, sitting by the fire – when in fact I am lying undressed in bed! Yet at the moment my eyes are certainly awake” (Descartes 145). By using simple experiences like these Descartes is able to emphasize that when a person is dreaming, they do not usually know they are dreaming, and the sensations they experience are as real as if they were awake.
One of his most famous arguments is known as the Dream Argument. During his explanation of this argument, the meditator tries to identify the difference between imagination and knowledge. Descartes’ meditator often claims that “he is convinced that he is in his dressing-gown, sitting by the fire. When in fact, he is lying undressed in bed” (Feinberg 243). Not only has he had encounters of thinking that he was awake, but was actually asleep, he has also experienced himself believing that he was sleeping, but was indeed awake.
Descartes introduces a "Method of Doubt" that allows him to systematically doubts structures of knowledge. To understand the dream argument, you need to understand its function in Descartes's argument. Within mediation one on his Mediations on First Philosophy Descartes establishes many areas in which he can call into doubt his existence and experiences. One of the arguments where he begins his questioning is the dream argument. In the dream argument he presents evidence in order to support his claim that one can never establish if they are actually dreaming or are awake.
Why can’t Descartes be certain about mathematical beliefs like the belief that 2+2=4? The truth that 2 + 2 = 4 does not rely on any sensible experience but is grasped entirely in our minds regardless of whether we are dreaming or awake.
However, Descartes accepts that humans can be wrong by relying on their sensory knowledge, though mostly on small objects in life. Because the senses can be incorrect, skepticism states that it isn't what Descartes searches for. Descartes tries to reassure himself, saying that it his sense must have some truth, since he is not a mad person. However, mad people are certain that what they see is real, and Descartes has just proven that his sensory knowledge can be wrong at times, so skepticism states that he can never be sure that he isn't insane. Skepticism also doubts whether people's lives are dreams or not, as people can confuse their dreams as real
Let’s imagine you are dreaming of a house, a garden, and a white picket fence. Despite the realism of the dream, this visual sensation is false even if they visually look real. Descartes go on to explain that, this visual sensation from our dreams must have been caused by external objects. Therefore, dreams can and do deceive us because the question “How do we know if we’re not dreaming now?” comes into play. Dreams visually deceive us.
