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 one thing Descartes cannot doubt is that he exists, because he thinks and question the world around him. Descartes felt that our senses and perception of can skew every aspect of our understanding of reality, so only the fact that he exists is without doubt. This reasoning is known as solipsism (1). Basically, everything seen, felt, heard, or experienced are misrepresented by perception. With perception skewing everything, the only certainty is mind and the thoughts it holds, not necessarily that the thoughts are correct.

In this section I will thoroughly discuss and explore both of Descartes arguments. Firstly, scepticism is the doubting of knowledge or the doubting of a belief. Descartes holds the view that to know something or attain a certain belief for example God is omnibenevolent, I must know that God is omnibenevolent, believe that God is omnibenevolent and have reasoning/evidence that God is omnibenevolent. I think Descartes definition of knowledge is logical because again using the example God is omnibenevolent, I can’t know that God is omnibenevolent if I don’t believe that it is true and if I have no justification or reasoning for believing that God is omnibenevolent then I can’t possibly be certain that He is omnibenevolent. Descartes believes without knowing, believing and having reasoning/evidence, I cannot know that God is real. Descartes argues that “it is prudent never to trust completely those who have deceived us even once” . Descartes argues that you cannot trust someone or something which has made you believe or accept a false truth. For example, in Descartes 6th Meditation he writes “sometimes towers which had looked round from a distance appeared square from close up; and enormous statues standing on their pediments did not seem large when observed from the ground”. This indicates that it is very easy to be deceived by someone or something which results in someone believing a false truth therefore I agree with Descartes that you cannot trust something which has deceived you more than once. Furthermore, looking at Descartes dreaming argument, the dreaming argument is an argument which infers when you are asleep, you can have dreams which do not allow you to distinguish whether you are asleep or awake. Dreams very often lead the dreamer to believing false situations which does not enable to dreamer to know they are asleep. The dreaming argument is about if you should trust

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

His belief in God even affected his theories on reality. One of his theories was that he was being deceived by a conniving and mischievous demon that was hell-bent on distorting his reality. The demon could be comparable to the evil dictator and the memory replacing machine in Total Recall. Despite the evil demon, Descartes did manage to reveal one very true thing and that is that he must exist if he truly is being deceived by the evil demon because he needs to exist in order to be deceived. He later summarizes this into his famous phrase “I think, therefore, I am.”(Descartes 136).

Descartes attacks the possibility of certainty with regards to the existence of small and universal elements with the possibility of our thoughts being altered by an omnipotent deceiver. In paragraph nine, he states, “How do I know that he did not bring it about that there be no Earth at all, no heavens, no extended thing, no figure, no size, no place, and yet all these things should seem to me to exist precisely as they appear to do now.” His point is that this omnipotent evil deceiver could create in our minds an understanding of mathematics and logic that is at odds with reality, causing us to construe everything wrongly. Thus Descartes ends this final and devastating doubt with the preliminary conclusion that everything he perceives can be called into doubt.

Descartes as a rationalist believes that knowledge comes from the mind alone. During the First Meditation, Descartes came to the conclusion that there must be some kind of evil deceiver that "leads him to a state of doubt" (Descartes 77). Descartes starts out with the fact that distant sensations are subject to doubt and uncertainty. He then goes on to try and cast doubt onto close sensations. Descartes starts off by stating that close sense perception must be certain because we are not crazy, and only a insane person would doubt what was right in front of them. Descartes then uses the dream argument to cast uncertainty on close sense perception because "they are as lively, vivid and clear as reality is when we are awake" (Descartes 76). Descartes then states that geometry and math are certain. "For whether I am awake or sleeping, two and three added together always make five, and a square never has more than four sides; and it does not seem possible that truths so apparent can be suspected of any falsity or uncertainty" (Descartes 98). Descartes comes to realize this certainty because math, geometry, and the simple sciences can be understood and proved through logic and reasoning. He then uses his Deceiver Argument to cast doubt on close sensations. He questions how we know for certain that God is good, and how we know that

Descartes answers to his arguments saying that the best way to prove something is real is to perceive it through our senses in order to identify it. He says that he can perceive God when he pays close attention but he never gives us an example of how does he perceive God through his senses. He just says that he manifests himself more than anything else. He says that now that he proved that there is a God he can ensure the truth of other things. He says that owing to this he can perceive other things evidently and now he cannot just say that those aren’t true. Descartes blames his memory of his unstable opinions since he cannot remember all the previous arguments he had against certain things. Descartes is fine with this since he believes that

This allows Descartes to begin to gain true knowledge, because his perfect being exists and would not allow him to be deceived all the time because perfection does not allow for that behavior.

     Through his philosophical search Descartes was able to find one indubitable certainty, that we are thinking beings. We always think, even when we have doubts that we are thinking we are still thinking because a doubt is a thought. Although Descartes found this one universal truth, he was still not able to believe in anything but the fact that he was a thinking being. Therefore he still doubted everything around him. He used this one certainty to try to find a system of knowledge about everything in the world. Descartes idea was to propose a hypothesis about something. For example he might say that a perfect being was in existence. He would go around this thought in a methodical way, doubting it, all the while trying to identify it as a certainty. Doubting everything was at first dangerous because in doubting everything he was also admitting that he doubted the existence of God, and thus opposing the church. However he made it a point to tell us at the beginning of his Discourse on Methods that what he was writing was only for himself and that he expected no one but himself to follow it (Descartes 14, 15). Descartes eventually managed to prove the existence of a higher being. He said that since he had the idea of a perfect being, then that perfect being must exist. His

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 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

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.

Descartes claims that God is all-powerful and completely good, yet gives no proof that God is good. If of course Descartes' belief is accepted. You assume that God does exist and that he is all powerful and that the idea of a perfect being does exist only because God put that idea there, then what is to say God is not an evil deceiver who can put any thought that God wishes you to think inside

Descartes’ method of arriving at the conclusion is by starting from scratch and considering whether there could be any ground of doubt for his beliefs. He was a rational philosopher who gave reason the utmost importance and led him to realise that many of his current beliefs were in fact based on uncertainty and thus false conclusions. Therefore, in order to avoid this problem and find secure knowledge of on what he can be certain of, he uses the method of doubting everything that he finds reason to doubt and consequently, being justified in rejecting the whole. He will: ‘withhold my assent from matters which are not entirely certain and indubitable than from those which appear to me manifestly to be false’ (Descartes 1641: 6)
