Essay on Descartes

     On the journey to find truth to base all thought upon, Descartes explains his first step in doing so. “Never accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgment than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.”(Kolak, Pg.228). Assuming that everything you see is fictitious, Descartes believed he had no senses at all; “body, shape, extension, motion, and place are unreal.”(Weissman, Pg.23). Our senses have failed us all at one point or another in our lives, so why use the senses as a base for thought? The most famous quote and philosophy by Descartes in history ever, “Je pense, donc je suis, cogito ergo sum” (Durant, Pg.639). “I think, therefore I am” was the first step towards a basis to understand truth, and leaning away from truth through the senses.

The cogito, “I think” is Descartes’ first certainty and his first step into knowledge. Descartes argues that there is one thing that he is most certain of and even the evil demon can manipulate and make him doubt. He cannot doubt that he thinks because even doubting of a form of thinking and that means that he will be thinking. Even if the demon made him doubt that he is thinking, he would be confident that he is thinking that the demon is making him doubt his thinking. He cannot also doubt that he exists and if he were to doubt of his existence, he would prove that he exists because of his thoughts, and thus his thinking means he exists and hence if he exists then he must be thinking of his existence. Therefore, Descartes extends his certainty

     This is where the wax argument comes into play. All the properties of the piece of wax that we perceive with the senses change as the wax melts. This is true as well of its primary properties, such as shape, extension and size. Yet the wax remains the same piece of wax as it melts. We know the wax through our mind and judgement, not through our senses or imagination. Therefore, every act of clear and distinct knowledge of corporeal matter also provides even more certain evidence for the existence of Descartes as a thinking thing. Therefore his mind is much clearer and more distinctly know to him than his body. At this

As the first “premise” of his proof Descartes makes a very important distinction between the various types of ideas. The first type of idea he discusses is ideas that are images of things. This type of idea, when thought of, is apprehended as an object of my thought, but there is something more embraced in the thought than merely the representation of the object. Now if these ideas are considered only in themselves, and are not referred to any object beyond them, they cannot, properly speaking, be false. This even applies to the will and affections, a second type of idea, for although I may desire objects that are wrong, it is still true that I desire them. The third type of idea is that of judgement. Descartes goal in this classification is to find in his mind which of the ideas are the proper bearers of truth and falsehood. Considered in themselves, ideas are not false nor are desires. The only place where mistakes can be made is in making judgements. As Descartes says, “And the chief and most common mistake which is to be found here consists in my judging that the ideas which are in me resemble, or conform to, things located outside me.” Descartes further classifies his ideas by their origin: those that appear

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.

Rene Descartes decision to shatter the molds of traditional thinking is still talked about today. He is regarded as an influential abstract thinker; and some of his main ideas are still talked about by philosophers all over the world. While he wrote the "Meditations", he secluded himself from the outside world for a length of time, basically tore up his conventional thinking; and tried to come to some conclusion as to what was actually true and existing. In order to show that the sciences rest on firm foundations and that these foundations lay in the mind and not the senses, Descartes must begin by bringing into doubt all the beliefs that come to him by the senses. This is done in the first of six

Descartes answers his seemingly hopeless skepticism from the first meditation with the Cogito. The basic point of his Cogito argument is that for me to either perceive awry, or even to doubt my own existence, I must exist. It is, as Descartes says, “’I am, I exist’ is necessarily true every time it is uttered by me or conceived in my mind (Med2, par3).” He makes two arguments for the Cogito in his second meditation. Descartes arrives at the Cogito through the notion of an omnipotent deceiver actually. He starts to question his own

He finds it plausible that we are all living in a dream and we have never experienced reality. He can no longer give any credence to his senses and finds himself in a place of complete uncertainty. Descartes comes to the conclusion that nothing can be perceived more easily and more evidently than his own mind. He has discovered that even bodies are not accurately perceived by the senses or the faculty of imagination, and are only accurately being perceived by the intellect. He also realizes that they are not distinguished through being touched, smelled, or tasted, but by being understood alone. (An apple is an apple because our mind tells us that it is an apple.) It is the faculty of reason that gives the knowledge and lets the mind know the truths and essences of objects. Descartes assumes that all of us can be decided by our senses, someone can see something far away, and then discover that is not what we thought it was. Or even a oar when is immerse half in water attempt to be bent, but instead is straight. Descartes think that we cannot always be sure of what we sense, and gives the example of himself seated by the fire.

Descartes' meditations are created in pursuit of certainty, or true knowledge. He cannot assume that what he has learned is necessarily true, because he is unsure of the accuracy of its initial source. In order to purge himself of all information that is possibly wrong, he subjects his knowledge to methodic doubt. This results in a (theoretical) doubt of everything he knows. Anything, he reasons, that can sustain such serious doubt must be unquestionable truth, and knowledge can then be built from that base. Eventually, Descartes doubts everything. But by doubting, he must exist, hence his "Cogito ergo sum".

In his Meditations on First Philosophy, Descartes strives first and foremost to provide an infallibly justified foundation for the empirical sciences, and second to prove the existence of God. I will focus on the first and second meditations in my attempt to show that, in his skepticism of the sources of knowledge, he fails to follow the rules he has set out in the Discourse on Method. First I claim that Descartes fails to draw the distinction between pure sensation and inference, which make up what he calls sensation, and then consider the consequences of this failure to follow his method. Second, I will show that in his treatment of thinking Descartes fails to distinguish between active and passive thinking.

Descartes has a very distinct thought when thinking about the mind, and how it relates to the body, or more specifically then brain. He seems to want to explain that the mind in itself is independent from the body. A body is merely a physical entity that could be proven to be true scientifically and also can be proven through the senses. Such things are not possible with the meta-physical mind because it is independent of the body. Building on his previous premises, Descartes finally proves whether material things exist or not and determines whether his mind and body are separate from each other or not. In Meditation Six, Descartes lays the foundation for dualism which has become one of the most important arguments in philosophy.

Descartes believes that knowledge comes from within the mind. This is a single indisputable fact to build on that can be gained through individual reflection. While seeking true knowledge, Descartes writes his Six Meditations. In these meditations, Descartes tries to develop a strong foundation, which all knowledge can be built upon. In the First Meditation, Descartes begins developing this foundation through the method of doubt. He casts doubt upon all his previous beliefs, including “matters which are not entirely certain and indubitable [and] those which appear to be manifestly false.” (Descartes, p.75, par.3) Once Descartes clears away all beliefs that can be called into doubt, he can then build a strong base for all true

really be applied to us as beings which we perceive. So what is the connection between what we believe to be us

Before these changes were apparent, Descartes pointed out the difficulties of relying on the senses, of the physical body. In section 31 of Meditation two, he says that the perception he has, "is a case not of vision or touch or imagination - nor has it ever been, despite previous appearances - but of purely mental scrutiny". Descartes shows that our senses cannot be used to have knowledge of things in the external world, and that knowledge of these things must come through the mind alone.

Firstly, Descartes deals with the issue of empiricism- the theory that our knowledge is derived from our sensory experiences. Since we know from everyday errors that our senses have the ability to deceive us fairly often so making our perceptions to be something that it is not. For example, there are lots of examples of optical illusions and the fact that the train tracks may appear to converge from a distance. Consequently, we ought to
