Comparison of Descartes and Heidegger
According to Descartes, the essence of material substance is simply extension, the property of filling up space. (Med. V) So solid geometry, which describes the possibility of dividing an otherwise uniform space into distinct parts, is a complete guide to the essence of body. It follows that there can be in reality only one extended substance, comprising all matter in a single spatial whole. From this, Descartes concluded that individual bodies are merely modes of the one extended being, that there can be no space void of extension, and that all motion must proceed by circular vortex. Thus, again, the true nature of bodies is understood by pure thought, without any information from the senses.
1. The Dream Problem
Second, Descartes raised a more systematic method for doubting the legitimacy of all sensory perception. Since my most vivid dreams are internally indistinguishible from waking experience, he argued, it is possible that everything I now "perceive" to be part of the physical world outside me is in fact nothing more than a fanciful fabrication of my own imagination. On this supposition, it is possible to doubt that any physical thing really exists, that there is an external world at all. (Med. I)
Severe as it is, this level of doubt is not utterly comprehensive, since the truths of mathematics and the content of simple natures remain unaffected. Even if there is no material world (and thus, even in my dreams) two plus three makes five and red looks red to me. In order to doubt the veracity of such fundamental beliefs, I must extend the method of doubting even more hyperbolically.
In the Sixth Meditation, Descartes finally tried to eliminate the dream problem by proving th...

This radical separation of mind and body makes it difficult to account for the apparent interaction of the two in my own case. In ordinary experience, it surely seems that the volitions of my mind can cause physical movements in my body and that the physical states of my body can produce effects on my mental operations. But on Descartes's view, there can be no substantial connection between the two, nor did he believe it appropriate to think of the mind as residing in the body as a pilot resides within a ship. Although he offered several tenatative suggestions in his correspondence with Princess Elizabeth, Descartes largely left for future generations the task of developing some reasonable account of volition and sensation, either by securing the possibility of mind-body interaction or by proposing some alternative explanation of the appearances.
In “Bad Dreams, Evil Demons, and the Experience Machine: Philosophy and the Matrix”, Christopher Grau explains Rene Descartes argument in Meditation. What one may interpret as reality may not be more than a figment of one’s imagination. One argument that Grau points out in Descartes essay is how one knows that what one think is an everyday experience awake is not all a part of a hallucination. He uses the example of dreams to draw a conclusion about is claim based on experiences one would experience with dreaming. He asserts that there are times when one wake up from a dream that seems to be “vivid and realistic” however soon finds that it was not. The experience of reality in the dream was all a part of the mind. If dreams seem to be reality and one would not have any concept that one is dreaming how does one know that one is not dreaming now? Descartes point is that one cannot justify reality in the sense that one could be dreaming right at this moment and not know therefore one cannot trust the brain as an indicator of what is reality.
According to Descartes, “because our senses sometimes deceive us, I wanted to suppose that nothing was exactly as they led us to imagine (Descartes 18).” In order to extinguish his uncertainty and find incontrovertible truth, he chooses to “raze everything to the ground and begin again from the original foundations (Descartes 59).” This foundation, which Descartes is certain to be the absolute truth, is “I think, therefore I am (Descartes 18).” Descartes argues that truth and proof of reality lies in the human mind, rather than the senses. In other words, he claims that the existence of material objects are not based on the senses because of human imperfection. In fact, he argues that humans, similarly to Plato’s Allegory of the Cave, are incapable of sensing the true essence or existence of material objects. However, what makes an object real is human thought and the idea of that object, thus paving the way for Descartes’ proof of God’s existence. Because the senses are easily deceived and because Descartes understands that the senses can be deceived, Descartes is aware of his own imperfection. He
Outline and assess Descartes' arguments for the conclusion that mind and body are distinct substances.
According to Descartes the essence of matter is extension, which he further explains is length, breadth, and depth. Also as implied earlier, the mind exists and it’s sole essence is thought. After considering that the
In the first meditation, Descartes makes a conscious decision to search for “in each of them [his opinions] at least some reason for doubt”(12). Descartes rejects anything and everything that can be doubted and quests for something that is undeniably certain. The foundation of his doubt is that his opinions are largely established by his senses, yet “from time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(12). First, Descartes establishes that error is possible, employing the example of the straight stick that appears bent when partially submerged in water, as mentioned in the Sixth Replies (64-65). Secondly, he proves that at any given time he could be deceived, such is the case with realistic dreams. Further, Descartes is able to doubt absolutely everything since it cannot be ruled out that “some malicious demon … has employed all his energies in order to deceive me” (15). The malicious demon not only causes Descartes to doubt God, but also sends him “unexpectedly into a deep whirlpool which tumbles me around so that I can neither stand on the bottom or swim on the top”(16). Descartes has reached the point where he must begin to rebuild by searching for certainty.
Elizabeth writes a letter to Descartes asking him to explain to her the relationship “there is between the soul, which is immaterial, and the body, which is material” (Margaret A.: p16). She seeks this clarification particularly on the aspect of how the soul influences the body movements. This question comes following a claim that Descartes had made “regarding the body and the soul” (Gordon B. and Katherine J.: p17 -19). He intimated that the body and the soul exist as single entities and that each has autonomous function. This is found in the philosophy of the dualism.
Moving up the tower of certainty, he focuses on those ideas that can be supported by his original foundation. In such a way, Descartes’s goal is to establish all human knowledge on firm foundations. Thus, Descartes gains this knowledge from the natural light by using it to reference his main claims, specifically the existence of God in Meditation III, and provide an explanation to his radical thoughts. In Meditation III “The existence of God,” Descartes builds his foundation of certainty in the natural light through the examination of God’s existence.

Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.
One of the ways in which Descartes attempts to prove that the mind is distinct from the body is through his claim that the mind occupies no physical space and is an entity with which people think, while the body is a physical entity and cannot serve as a mechanism for thought. [1]
Descartes’ first two Meditations are arguably the most widely known philosophical works. Because of this, one can make the error of assuming that Descartes’ method of doubt is self-evident and that its philosophical implications are relatively minor. However, to assume this would be a grave mistake. In this paper, I hope to spread light on exactly what Descartes’ method of doubt is, and how, though it furnishes challenges for the acceptance of the reality of the external world, it nonetheless does not lead to external world skepticism.
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 different steps that he named "Meditations" because of the state of mind he was in while he was contemplating all these different ideas. His six meditations are "One:Concerning those things that can be called into doubt", "Two:Concerning the Nature of the Human mind: that it is better known than the Body", "Three: Concerning God, that he exists", "Four: Concerning the True and the False", "Five: Concerning the Essence of Material things, and again concerning God, that he exists" and finally "Six: Concerning the Existence of Material things, and the real distinction between Mind and Body". Although all of these meditations are relevant and necessary to understand the complete work as a whole, the focus of this paper will be the first meditation.
Only halfway; too many things are left up in the air, and the language is not quite clear. The mind and body can each exist separately and independently of one another. But they also need one another to work properly. This relationship is why the mind and body argument was shown with the sailor and ship scenario. By claiming that the mind and body were similarly related to each other as the sailor and the ship, Descartes was giving the average but intuitive reader something to ponder about while trying to make up his or her own mind about the relation between mind and body.
But his habitual ideas and opinions are still present no matter how hard he tries not to present them, to solve this problem he decides that all of his opinions are false. Descartes finds himself certain about one thing that nothing is certain. Resorting back to the idea that his senses are the only way he is able to obtain the truth in life, he believes that his senses are apart of his mind and body. He uses a honeycomb to examine this topic that the body and mind are one. The wax changes shape therefore he uses imagination to understand it
In Meditation Six entitled “Concerning the Existence of Material Things, and Real Distinction between the Mind and Body”, one important thing Descartes explores is the relationship between the mind and body. Descartes believes the mind and body are separated and they are two difference substances. He believes this to be clearly and distinctly true which is a Cartesian quality for true knowledge. I, on the other hand, disagree that the mind and body are separate and that the mind can exist without the body. First, I will present Descartes position on mind/body dualism and his proof for such ideas. Secondly, I will discuss why I think his argument is weak and offer my own ideas that dispute his reasoning while I keep in mind how he might dispute my argument.
