Descartes Rationalism

René Descartes believed that all truth could be found by rationalization, that it is not that any one person lacks the ability to come to the conclusion of truth, but that we all think differently and do not analyze situations in the same way. To understand his strategy, you must first understand the type of life that Descartes lived. Descartes was always a very intelligent person with a passion for learning. He spent much time studying in school in order to learn about truth and the world, but what he found was that he had not actually found

In order to weigh up these arguments, it is important to understand Descartes’ reasons for formulating them: Descartes’ believes that it is important to be certain of the things that one believes to be true which, in turn, causes him to question the things that he has been certain of thus far. Because of this, he forms these arguments to further consider his theories about doubt and what it is to be truly certain of anything.

My initial approach to René Descartes, in Meditations on First Philosophy, views the third meditation’s attempts to prove the existence of God as a way of establishing a foundation for the existence of truth, falsity, corporeal things and eventually the establishment of the sciences. When viewed in this light, Descartes is accused of drawing himself into a ‘Cartesian circle,’ ultimately forcing this cosmological proof of God to defy Cartesian method, thus precipitating the failure of the third, fourth, fifth and sixth meditations. This approach to the meditations, in the order with which they are presented, allows me to state that a proof of the existence of God cannot hold

In the first meditation, "Concerning those things that can be called into doubt", Descartes main goal is to distinguish what it is he can take to be true, and what supposed truths hold even the smallest degree of doubt. When he reviews all of his opinions he concludes "eventually [he] is forced to admit that there is nothing among the things [he]believed to be true which it is not permissable to doubt--and not out of frivolity or lack of forethought, but for valid and considered reasons. Thus [he] must be no less careful to withhold assent henceforth even from these beliefs then [he] would from those that are patently false, if [he wishes] to find anything certain."(Pg62) At the beginning of Descartes' meditations, he finds that there is really no concrete pillars of knowledge to base the foundations of his supposed

In the meditations, Descartes evaluates whether or not everything we know is a reality or a dream. Descartes claims that we can only be sure that our beliefs are true when we clearly and distinctively perceive them to be true. As the reader analyzes the third meditation, Descartes has confirmed that some of his beliefs are in fact true. The first is that Descartes himself exists. This is expressed in what has now become a popular quote known as the “Cogito” which says, “I think therefore I am. His second conclusion is that God exist and that he is not a deceiver. Descartes then presents his arguments to prove the existence of God. He argues that by nature humans are imperfect beings. Furthermore, humankind could not possibly be able to comprehend perfection or infinite things on their own. He writes, “By the name of God I understand a substance that is infinite, independent, all-knowing, all powerful, and which myself and everything else…have been created.”(16) Descartes uses this description of God to display the distinction between God and man.

Rene Descartes, a rationalist, said that each person contains the criteria for truth and knowledge in them. Finding truth and knowledge comes from the individual themselves, not necessarily from God. Descartes also believed that reason is the same for every single person. Descartes believed that nothing could be true unless we as humans could perceive it. He also believed that you could break down things into smaller simpler parts. Descartes also believed that there was a relationship between the mind and body. He also believed that the idea of being perfect originated from God since God himself was perfect. He also integrates his mathematical concepts into his methodology. Descartes also applied doubt to his ideas before he

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' 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".

Rene Descartes is a modern French philosopher, who is famous for his line, “I think, therefore I am.” The meaning of this quote is that he must exist because he has the ability to think. In Descartes most famous work, The Meditations, he starts off by doubting everything, which is known as the Method of Doubt. He believes that our senses are always deceiving us in some way and so our senses are unreliable in proving anything. By this, he means that when we use our senses, such as our vision, to look at something, the way that the object looks from afar is different from the way it looks upfront, thus, deceiving us. However, Descartes

     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

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

Renee Descartes, as a Rationalist viewed knowledge as something that we achieve through reason. Descartes begins his theory of knowledge by assuming that nothing exists. By doing this he would have to trust nothing. Not his senses, not anything that he has thought. As a Rationalist he sought to eliminate all doubt and anything else that wasn 't completely credible. Because he found that his senses were not one hundred percent reliable, as he found they sometimes deceived him, he did not trust them. Descartes believed that in order to obtain knowledge, there must be a rational method for obtaining it, and that the use of the senses, or any personal experience was not a reliable source. Finally, in Meditations on First Philosophy he concludes that he is a thinking thing: “I think, therefore I am”. He knows that this is true because he thinks, and to disprove that would require thinking and since he

Rene Descartes was a philosopher of the 17th century. He had this keen interest in the search for certainty. For he was unimpressed with the way philosophy is during their time. He mused that nothing certain was coming forth from all the philosophical ideologies. He had considered that the case which philosophy was in was due to the fact that it was not grounded to something certain. He was primarily concerned with intellectual certainty, meaning that something that is certain through the intellect. Thus he was named a rationalist due to this the line of thought that he pursued. But in his work in the meditation, his method of finding this certainty was skeptical in nature; this is ‘the methodic doubt’.

When someone makes a bold statement, the general consensus is that they should have some sort of reasoning to back it up. This is exactly what Descartes thought. His journey to seeking truth first started when he was a child. He was educated in all subjects, but just as soon as they ended, he was curious for more. So he went out into the world to try to find the truth he had been looking for. While he did learn new things, he was never satisfied. Finally, when he had exasperated the books and world, he was left with nothing other than himself. But this put him exactly where he needed to be. From meditative, self reflection he found his truth. He wrote on page 64, “I think, therefore I am”. Descartes concluded that nothing was for

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)
