How Does Descartes Ability To Think He Exists

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

Descartes’s first, and arguably most important deduction, is that he must exist, even if nothing around him does. He deduces that “it necessarily had to be the case that I, who was thinking this, was something” (Descartes 18), leading him to his famous axiom “I think, therefore I am” (Descartes 18). Even if his senses, his prior knowledge, and anything about his physical body and life are a fabrication, his mind itself must exist. This crucial discovery is the basis of Descartes’s philosophical musings. Descartes takes this single, certain fact and expounds upon it to “confirm” that the soul, God, and many other things certainly exist outside of his mind. Concerning things outside of his mind, Descartes determines that “they are not something I have fabricated; rather they have their own true and immutable natures” (Descartes 88). Using triangles as an example, Descartes reasons that they have “a certain determinate nature, essence, or form which is unchangeable and eternal, which I did not fabricate, and which does not depend on my mind” (Descartes 88). Concerning his body itself, Descartes reasons that his mind and body are tightly joined; “when the body is in need of food or drink, I should understand this explicitly, instead of having confused sensations of hunger and thirst” (Descartes 98). By determining that things such as his body and surroundings did in fact exits outside o f his mind, Descartes can start to “confirm” what he believes to be the true nature of God by his A priori

When Descartes remembers occasions when he is dreaming, he falsely believes he is awake. Reflecting on this, Descartes thinks he cannot

By the first premise Descartes refers to an activity that the body does not participate in. For instance, perception and walking are two activities which either directly requires the body (walking) or relies upon the body (perception). The activity of thinking can be done without a body. You can clearly and distinctly imagine yourself without a body, but you cannot imagine not thinking. Premise 2 indicates this distinction even more. Since the activity of thinking is separate from the body then this activity does not fall into doubt. Anything the body senses or is part of the body can be doubted because the mind’s eye would only perceive the image the body creates which has previously be shown to be dubious. A possible objection is that Descartes is pointing to another representation which the body has created. For instance, the body has created the image of thinking which the mind’s eye views. In addition, could we not be dreaming and thus deceived that we are thinking or could there be a demon deceiving

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

As a thinking entity, Descartes is a consciousness mind aware of the potential to engage in various modes of existence. To the numerous operations of “thought” he includes doubting, understanding, affirming, denying, willing, refusing, imagining, and sensing. As varied and manifold as these operations appear, they are but expressions of two principal types of conscious activity, to which Descartes eventually traces the nature of error. Thinking and reasoning, together with all belief in general, depend upon the operation of the twin faculties “knowing” and “choosing,” or the free will. Garrett Thompson writes:

Something very essential to know about Descartes is his idea of Cogito Ergo Sum; I think, therefore I am. He believes that he exists because he is thinking, making him a thinking thing. Descartes first premise states, "I have a clear and distinct idea of myself, in so far as I am simply a thinking, non-extended thing" (Descartes, 54). The first thing that we need to understand from this premise is what Descartes means by extended; to occupy space. So, since he believes that he is not an extended thing, it follows that he does not take up space. Given this, he looked inside himself and saw no parts within his mind, no space or boundaries that his mind contains. In addition, the mind provides a place for free will and faith, which are not parts but different ways of thinking. He rationalizes this by making the mind of a qualitative substance. By saying that only things that can be measured must be of a material substance and those things that cannot be measured are of a thought like substance. The relation between body and mind now seem to be more divided since he believes that his mind is not extended. In short, this premise states that the mind has no parts, making it indivisible.

This then leads him to question the existence of God, and then whether he himself truly exists as well. Descartes concludes his claim in stating, “So after considering everything very thoroughly, I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind,” (25). Therefore, in spite of everything he is skeptical of, Descartes manages to believe that his true existence is not something worthy of doubt.

“During these few days I am examining if anything in the world exists, it obviously followed that I exist” (84) Descartes states that a being can be certain of their existence if they have the ability to think and comprehend thoughts. He also adds that thoughts imagination etc are objectively real. So if thoughts are real in their own right, then the creator of those thoughts must also be real or exist “Here I make my discovery, thoughts exist; it alone cannot be separated from me” (65) Based on the evidence above it allows us to see that Descartes arguments about his natural existence seem coherent and

He cannot say that God exists, because there remains the possibility that his thoughts are in fact originating from himself (in which case there would be no need for God). Since he has abandoned all notions of existence and certainty, which includes his own body and senses, is it possible that he himself does not exist? To think a thought is bound to existence by definition; one must exist first before having the ability to think. Even if an all-powerful deceiver made it so that I do not exist, it would generate a contradiction since I cannot think that I exists if I don't. (25) Thinking about existing requires existence as a prerequisite. Descartes has arrived at his first truly tangible and useful element of truth: that it is necessarily true that he exists.

Having assured himself that he exists and that the essential nature of his self includes at least the capacity to think he then explored the question What else am I? (Section 27) and reached this conclusion: But then what am I? A thing that thinks (res cogitans). What is that? A thing that doubts (dubitans), understands (intelligens), affirms (affirmans), denies (negans), wills (volens), refuses (nolens), and that also imagines (imaginans) and senses (sentiens) (Section 28). Descartes acknowledges that thinking includes doubt, understanding, affirmation, denial, will (volition), refusal, imagination, and senses .

So just because you think, you are not actually. Descartes admits this in the above statement as he can not clearly decipher if he is dreaming or not, so what is he really

The idea behind this reasoning comes from the judgement that while in certain dreams, a person may be convinced that they are experiencing everything awake, when in fact they’re dreaming. The lack of distinctness and certainty that arises from whether he could, at the moment, be awake or not brings Descartes to the conclusion that he cannot logically say he is awake, when he thinks he is. In addition, this only reinforces all perceptual beliefs to be false, and a form of

Descartes’ claim of “I think, therefore I am”, is an attempt to establish a firm foundation for the understanding of the universe and explores the ideas of the self and what we can know to be real. However, there is one major flaw in this approach. That flaw is how we are to create this foundation when before it we had nothing and the paradoxes in the creating definitions of words.

Descartes concludes that the attribute of thinking is the only quality that he can justifiably claim at this point. But he is quick to point out that thinking is the only attribute about which he is sure; not that thinking is the only attribute that he has. Nevertheless, this is the starting point of a radical ontological distinction that carries Descartes through his Meditations. That distinction is between a "thinking thing" and a corporeal body. The two are mutually exclusive. A "thinking thing" is nonphysical or spiritual in nature, whereas a corporeal body is physical, but not capable of consciousness or thought. For Descartes, a "thinking thing" is consciously aware of what is around it and doubts, understands some, is ignorant of most, imagines, and feels.
