Beliefs Beyond Doubt, What All Other Respond To: Rene Descartes' "Meditations on First Philosophy"

In “Bad Dreams, Evil Demons, and the Experience Machine: Philosophy and The Matrix”, Christopher Grau analyzes Rene Descartes argument concerning reality. The argument starts on page 181 in the bottom left hand corner of the page and continues onto page 182, ending at the bottom right corner of the page. In this text, Grau explains Descartes argument that what one may interpret as reality may not be more than a figment of their imagination and then uses it to develop his own argument. Grau explains that you cannot know whether you are in the dream world or the real world, and therefore argues that we cannot be sure that our beliefs about the world are true.

Descartes’ dream argument from his First Meditation leads people to doubt their senses. Descartes begins the argument with thinking that we can tell whether we are dreaming or not based on our experiences. However, he then realizes that it is not possible to recognize if we are dreaming or are awake. Since we cannot distinguish between the two, our perceptions and senses can be doubted. This is the purpose of the dream argument and proven true by Descartes, which makes the argument convincing.

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

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’ 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

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.

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

Descartes has written a set of six meditations on the first philosophy. In these meditations he analyzes his beliefs and questions where those beliefs were derived from. The first mediation of Descartes discusses his skeptical hypotheses; questioning the validity of the influences of his knowledge. He has a few main goals that are expressed through the first meditation. First off, Descartes wants to build a firm foundation of knowledge that is also concrete. Through probing his mind for answers to all of his skeptical thoughts, he hopes to eliminate the skepticism and find true, unquestionable knowledge. Descartes has mapped out ways to

My intent in this essay is to illustrate that the arguments regarding the existence of God and the fear of deception in Descartes’ Meditations on First Philosophy, are quite weak and do not justify his conclusions. To support these claims, I will begin by outlining two specific meditations and explain the proposed arguments. Later, I will critically analyze his arguments, revealing unjust conclusions. Doubts surrounding the text include the suggested characteristics of God, the condition of perfection, and the nature of deceit. A wrap up will include a discussion on whether or not Descartes (also referred to as Renatus) succeeded in his project.

This essay attempts to explain Descartes’ epistemology of his knowledge, his “Cogito, Ergo Sum” concept (found in the Meditations), and why he used it [the cogito concept] as a foundation when building his structure of knowledge. After explaining the concept I give a brief evaluation of his success in introducing and using this cogito as a foundation. Finally, I provide reasons why I think Descartes succeeded in his epistemology.

In Rene Descartes, Meditations on First Philosophy, Descartes does and experiment with wax to try to prove that things actually exist in this world. This essay is going to prove how we can tell that things actually exist and what can perceive the wax.

The dream argument presented by Descartes states that it is logically possible that we are in a never-ending dream. Dreams can feel immensely real until we wake up, for example the “falling dream”. Though if we were to never wake up, we would never notice that our experiences were not real. Since there is no way to certainly tell that we are not dreaming right now, we cannot acquire knowledge through our senses or be certain of our synthetic beliefs. Another reason we can doubt our synthetic beliefs is because our senses could be mistaken.

Firstly, this argument is contradictory as it disagrees with his statements about dreams. He states, “and my astonishment is such that it is almost capable of persuading me that I now dream.” (Descartes, 1641). A dream is not a real point in time, it is a made up situation in which you think about while asleep. For example, if you think you are riding a bike in a dream, you are not actually riding that bike in reality.
