Descartes Dream World Summary

Improved Essays
Descartes’ Dream World Worry Descartes has a very important plan in mind for his Meditations on First Philosophy and part of this plan involves bringing everything we know into question and finding what it is that we can know about the world around us and about ourselves. He wants to do this in order to find a solid base of what we certainly know, so he can build up what we can know onto that certainty. In these meditations he brings to light some problems with knowing things that we perceive, the problems include his sanity, an evil-genius, and the possibility that anything beyond ourselves is just a dream, a simulated world within our minds. This last one, the dream world problem is the one we will concern ourselves with here. Through these …show more content…
In the very last paragraph of his meditations he sprinkles a handful of ideas out in attempt to finish his defeat of worries he has yet to vanquish appropriately. This includes our worry concerned here in. His final attack on this problem is a problem of continuity, memory, and intellect. The main difference between dreams and being awake is the continuity of perceptions. He uses a thought experiment involving a man who appears out of nowhere and how within a dream this would not seem odd but surely would if one was awake. (Descartes 89) The connections between things that have happened and things that are happening is something that is not necessary within a dream but it is our idea of reality. The argument in premise, conclusion format would be as …show more content…
Hume agrees that we cannot connect our perceptions to any external objects (Hume XII:I) and goes on to argue “For here is the chief and most confounding objection to excessive scepticism, that no durable good can ever result from it” (Hume XII:II) that this kind of questioning, what he refers to as excessive scepticism, does nothing for us. Hume argues that this questioning is not something that we can base our lives on. That our morality and principles are not based on reasoning but on sentiment. (Hume XII:III) How we live our life is based on our principles and it is not within us to reason out things such as existence and morals, but that we should create these of our sentiments. And he shows that whether our external world is an ultimate reality or not, it does not matter to our actually morality and lives. As one can see Descartes sets up a problem and in its defeat he hopes to solidify his future position on knowledge but unfortunately he is unable to truly vanquish his dream world worry in a satisfactory way. Unfortunately for him this defeat is essential to his overall goal to argue what it is that we can know. Though the dream world worry may not be a large problem in our day to day lives, its persistence undermines Descartes overall goal of proving what we can know and proving

    This means that his premises make the conclusion more likely, but does not guarantee that the conclusion will be true. We interpreted Descartes’ conclusion as: if we never know if we are awake or dreaming, than we cannot be aware of our surroundings, ever. By coming to this conclusion from his premises, the conclusion is still not guaranteed; therefore making it an inductive argument. I don’t believe that it is a fair statement to say that every single person is never aware of their surroundings. This is a form of an enumerative induction.…

    George Berkeley argues that an objective reality does not exist. He argues for idealism, the belief that the external world does not exist and only the mind and ideas do, by arguing against materialism, that an objective reality does exist. Berkeley believes that an objective reality does not exist because of issues that come with materialism. However, his points do not make much sense as he relies on faulty ideas. He presents his argument by mentioning how materialism is unverifiable; that we cannot verify there is an objective reality, pointless; there is no need to posit an external world, and incoherent; our senses cannot be external objects.…

    Although Equality 7-2521 had hope for individualism, he thought like a collective. “We must not keep our secret to ourselves, not buried under the ground. We must bring it to the sight of men” reveals how selfless Equality 7-2521 was because he had just discovered something that could possibly be life changing and he did not think of keeping it to himself. (Rand 60) The light symbolized the selfless part of Equality 7-2521 because even though he was starting to think…

    Thirdly, the reason why we lack insight into our dreaming condition is not because our dreams and awake episodes have similar content, as Descartes implied, but because of the distinct characteristic that dreams possess. Dreams have a kaleidoscopic effect upon the dreamer which prevents them from having insight into their own state of consciousness. The environment and situation is always shifting so there is no opportunity for the dreamer to rationally reflect upon the current state of affairs, which would lead him to conclude that he is in fact dreaming. Descartes might contest against my theory by saying that our lives could be a realistic and dulled out version of these kaleidoscopic dreams, and this lack of awareness is an outcome from the identical…

    Nagel belief is that everything is absurd in life. He believes that life has no tangible meaning and there is no reason why we should think we could make life meaningful at all. But, we continue to live with defiance, despair, or with an ironic smile. Life is not as important as we had once thought, but that is not a reason to hate life or to feel sadness. Nagel does not believe that life is absurd is about life meaning nothing because it will mean nothing in the distant future.…

    We often think subjectively, which is thinking based on personal feelings and emotions. That does not mean that we cannot go through making small changes. The split second that we stopped thinking about our actions the selfish instinct has returned. If it is a choice to think this way as Wallace states then that is fair enough. However, in the end we still will not have completely reset our default setting; is just our basic human nature to not think about these things daily.…

    Melissa would argue that Matthew’s condition is not analytic because, his quality of life will not be abstract, Matthew cannot maintain abstract thoughts in his condition. Secondly, Matthew’s condition states that Matthew will not likely be himself due to his severe head trauma. Therefore, Matthew’s situation is nonsense. However, Melinda could argue that Hume’s basic definition of mental activity is that materials come in, it is processed, resulting in true knowledge. It shouldn’t matter if it isn’t abstract or whether he will not be truly himself.…

    In my opinion, Lord Henry does not deliberately attempt to destroy Dorian’s life, however he is cynical in the fact that he treats Dorian’s soul as inconsequential and therefore is able to use Dorian as type of puppet with no restrictions. This undoubtedly represents Lord Henry’s hedonistic influence as in fact responsible for the change in Dorian Gray’s nature although he might not intend for Dorian to be led to his demise. In conclusion, through the art of influence and manipulation, Lord Henry’s influence on Dorian Gray is rather unfortunate since he never had the opportunity to discover himself as well as his values; it was rightfully taken away from him. And because of this, Lord Henry is considered to be entirely responsible for the transformation that Dorian undergoes. Consequently, Dorian becomes lost in the immorality of sinfulness and is led towards a life filled with guilt, murder, and self indulgence all due to the corrupt, persuasive statements that Lord Henry deliberately…
