Descartes Third Meditation

In Descartes’ First Meditation, Descartes’ overall intention is to present the idea that our perceptions and sensations are flawed and should not be trusted entirely. His purpose is to create the greatest possible doubt of our senses. To convey this thought, Descartes has three main arguments in the First Meditation: The dream argument, the deceiving God argument, and the evil demon “or evil genius”. Descartes’ dream argument argues that there is no definite transition from a dream to reality, and since dreams are so close to reality, one can never really determine whether they are dreaming

In the Sixth Meditation, Descartes makes a point that there is a distinction between mind and body. It is in Meditation Two when Descartes believes he has shown the mind to be better known than the body. In Meditation Six, however, he goes on to claim that, as he knows his mind and knows clearly and distinctly that its essence consists purely of thought. Also, that bodies' essences consist purely of extension, and that he can conceive of his mind and body as existing separately. By the power of God, anything that can be clearly and distinctly conceived of as existing separately from something else can be created as existing separately. However, Descartes claims that the mind and body have been created separated without good reason. This

By the start of Meditation Four Descartes has established the reliability of his clear and distinct criterion of knowledge, and he has concluded that he exists as an essentially thinking thing and that the idea of an infinite, perfect being entails God's existence. Descartes has also eliminated concern about being systematically deceived, since acting in such a way would be indicative of some deficiency rather than the exercise of some power, and God is perfect. This generates further questions, as humans do regularly judge falsely, even without the meddling of a malicious, deceptive being (99). Given God's nature, attributing error to him is unacceptable, but, conversely, how could humans be blamed for the faulty faculty of judgement that

In Meditation Two of René Descartes’ Meditation on First Philosophy, he notes the sight of “men crossing the square.” This observation is important as Descartes states, “But what do I see aside from hats and clothes, which could easily hide automata? Yet I judge them to be men.” This is an important realization as Descartes argues that instead of purely noticing the men through sight, it is actually “solely with the faculty of judgement,” the mind, that perceives and concludes that the thing wearing a hat and clothes are men. I argue that this view of the outside world by Descartes is incomplete as his idea of “I” is faulty, as well as having a misunderstanding on the importance of the senses.

In Descartes’s Meditations III, the Meditator describes his idea of God as "a substance that is infinite, eternal, immutable, independent, supremely intelligent, supremely powerful, and which created both myself and everything else."(70) Thus, due to his opinion in regards to the idea of God, the Meditator views God containing a far more objective reality than a formal one. Due to the idea that of God being unable to have originated in himself, he ultimately decides that God must be the cause of the idea, therefore he exists. The meditator defines God as such, “by ‘God’ I mean the very being the idea of whom is within me, that is, the possessor

In the Meditations, Rene Descartes attempts to doubt everything that is possible to doubt. His uncertainty of things that existence ranges from God to himself. Then he goes on to start proving that things do exist by first proving that he exists. After he establishes himself he can go on to establish everything else in the world. Next he goes to prove that the mind is separate then the body. In order to do this he must first prove he has a mind, and then prove that bodily things exist. I do agree with Descartes that the mind is separate from the body. These are the arguments that I agree with Descartes.

In the “Second Meditation,” of “Meditations on the First Philosophy,” Descartes contends that, even if a “malicious deceiver” was purposefully attempting to trick him, one thing is “necessarily true”. “I am…only a thing that thinks…a thinking thing.” From this, Descartes asks, “What else am I?” His answer is that he is not just a body, or a “…thin vapour which permeates the limbs…” He is something, which is identical with his awareness of himself yet, what that is, he is not sure. Accordingly, Descartes can only make judgments about the things known to him, because judgment is thinking, and thus, he knows that he exists. This, for Descartes, is the first thing he can be certain of, that he does exist, as something that thinks.

Descartes believes that knowledge comes from within the mind, 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

Descartes started Meditation IV by stating that God doesn’t deceive. I think that the start of his argument falls into the same problem with Meditation III that the principle of sufficient reason is assumed because we don’t have sufficient knowledge about God; therefore, we cannot conclude that God doesn’t deceive. Similarly, he concluded that his error is a defect of God, which God cannot be hold accountable. We don’t have sufficient knowledge to assume that God doesn’t give bad faculty.

At the beginning of Meditation three, Descartes has made substantial progress towards defeating skepticism. Using his methods of Doubt and Analysis he has systematically examined all his beliefs and set aside those which he could call into doubt until he reached three beliefs which he could not possibly doubt. First, that the evil genius seeking to deceive him could not deceive him into thinking that he did not exist when in fact he did exist. Second, that his essence is to be a thinking thing. Third, the essence of matter is to be flexible, changeable and extended.

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

Descartes’ first meditation, his main objective is to present three skeptical arguments to bring doubt upon what he considers his basic beliefs. Descartes believes this to be an intricate part of his complete epistemological argument. Descartes skeptical arguments are not intended to be a denial of his basic beliefs. On the contrary, he uses these arguments to help prove one of his main theses, which is the existence of God. One of the main premises that Descartes uses in his proof for the existence of God comes from the evil demon argument, which he proposed, in the first meditation. It is this evil demon argument, which will be the topic of the following discussion.

At the beginning of the fourth meditation Descartes has developed three main certainties: 1) God exists. The understanding that God exists, comes from the intellect and not from the senses or the imagination therefore God exists 2) God is not a deceiver because deceiving is a sign of weakness or malice and because God is perfect he would not be allowed to do things of such evil nature. And 3) if God created him, God is responsible for his judgment, and so his ability to judge must be sound; so long as he uses it correctly. Yet, If God has given Descartes indubitable judgment how is it Descartes makes an error from time to time?

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".

The main two aims for the meditator Descartes are to show that the source of scientific knowledge, as we know it today, does not lay in our senses but the mind, and the compatibility between religion and science (Descartes 35). He aims to split the world into body and mind, where science will deal with the body and religion with the mind.
