In the Discourse of Method and Meditations, Descartes performs a thought experiment which consists of putting aside all knowledge of things that rely upon man’s ideas. In doing so, Descartes reveals the idea of perfect certainty in man that is “inseparable from [his] nature (84). Through this, Descartes affirms the immovable and certain nature of an external being. Not only is he able to come to this conclusion, but also likewise believes that man is a thing that thinks, “[who] doubts, [who] affirms, [who] denies” (91). For a man is an existing thing who has a mind, which thinks. Man’s finite being affirms his dependability of God. This is the case for two reasons. One way in which man’s finitude confirms his dependability of God is seen through
man’s ability to attain knowledge. Descartes will affirm this statement by separating knowledge into three distinct categories; thoughts that are capable of change, thoughts formed from experience and thoughts that are placed in man by God himself. Another way in which man’s finitude confirms is dependability of God is seen through man’s understanding of reality. Descartes will similarly separate reality into distinct parts in order to ratify man’s dependability on God. One that all objects within themselves contain objective reality and that likewise, formal reality must also exist.
In constructing his argument for God's existence, Descartes analyzes several aspects of the nature of human thought. He begins by outlining the various types of thoughts we have, which include ideas, thoughts, volitions and judgments. Ideas, or images of ideas can only exist within the mind and are certain of existence. Volitions, or choices are firmly within the mind and are also certain. Emotions, such as love, fear, hate, all exist in the mind and are certain as well. Judgments involve reference to effects outside the mind and are subject to doubt. Therefore, judgments are not certain and distinct. Descartes believes that images, volitions, and emotions are never false but it is our judg...
Through Descartes’s Meditations, he sought to reconstruct his life and the beliefs he had. He wanted to end up with beliefs that were completely justified and conclusively proven. In order to obtain his goal, Descartes had to doubt all of his foundational beliefs so that he could start over. This left Descartes doubting the reality of the world around him and even his own existence. In order to build up to new conclusively proven and justified true beliefs, Descartes needed a fixed and undeniable starting point. This starting point was his cogito, “I think, therefore I am.” In this paper I will argue that Descartes’s argument that he is definite of his own existence, is unsound.
Baird and Kaufmann, the editors of our text, explain in their outline of Descartes' epistemology that the method by which the thinker carried out his philosophical work involved first discovering and being sure of a certainty, and then, from that certainty, reasoning what else it meant one could be sure of. He would admit nothing without being absolutely satisfied on his own (i.e., without being told so by others) that it was incontrovertible truth. This system was unique, according to the editors, in part because Descartes was not afraid to face doubt. Despite the fact that it was precisely doubt of which he was endeavoring to rid himself, he nonetheless allowed it the full reign it deserved and demanded over his intellectual labors. "Although uncertainty and doubt were the enemies," say Baird and Kaufmann (p.16), "Descartes hit upon the idea of using doubt as a tool or as a weapon. . . . He would use doubt as an acid to pour over every 'truth' to see if there was anything that could not be dissolved . . . ." This test, they explain, resulted for Descartes in the conclusion that, if he doubted everything in the world there was to doubt, it was still then certain that he was doubting; further, that in order to doubt, he had to exist. His own existence, therefore, was the first truth he could admit to with certainty, and it became the basis for the remainder of his epistemology.
Descartes argues that we can know the external world because of God, and God is not a deceiver. Descartes’ core foundation for understanding what is important comes from three points: our thoughts about the world and the things in it could be deceptive, our power of reasoning has found ideas that are indubitable, and certainty come by way of reasoning. Once we have a certainty of God, and ourselves then we are easily able to distinguish reality from dreams, and so on. God created us and gave us reason, which tells us that our ideas of the external world come from God. God has directly provided us with the idea of the external world. The concept of existence, the self, and doubt could not have existed on its own; therefore they had to be created by someone to have put them in our mind. That creator is God, who is omnipotent and perfect. God is not a deceiver to me; God is good, so therefore what I perceive really does exist. God without existence is like a mountain without a valley. A valley does not exist if there is no mountain, and vice versa a mountain is not a mountain with out a valley. We cannot believe or think of God without existence. We know the idea of God, and that idea inevitably contains his existence. My thought on god is clear and distinct that he is existent. Descartes’ now has ‘rebuilt’ the world, solely because of his power and reasoning. Descartes’ is only able...
In this paper, I will explain how Descartes uses the existence of himself to prove the existence of God. The “idea of God is in my mind” is based on “I think, therefore I am”, so there is a question arises: “do I derive my existence? Why, from myself, or from my parents, or from whatever other things there are that are less perfect than God. For nothing more perfect than God, or even as perfect as God, can be thought or imagined.” (Descartes 32, 48) Descartes investigates his reasons to show that he, his parents and other causes cannot cause the existence of himself.
Rene Descartes meditations on the existence of God are very profound, thought-provoking, and engaging. From the meditations focused specifically on the existence of God, Descartes uses the argument that based on his clear and distinct perception that cannot be treated with doubt, God does exist. In the beginning of the third meditation, Descartes proclaims that he is certain he is a thinking thing based on his clear and distinct perception, and he couldn’t be certain unless all clear and distinct perceptions are true. Before diving into the existence of God, Descartes introduces smaller arguments to prove the existence of God. For example, Descartes introduces in his argument that there are ideas in which he possess that exists outside of him. Utilizing the objective versus formal reality, Descartes states “If the objective reality of any of my ideas turns out to be so great that I am sure the same reality does not reside in me, either formally or eminently, and hence that I myself cannot be its cause, it will necessarily follow that I am not alone in the world, but that some other thing which is the cause of this idea exists” (29). In other words, the ideas of objective reality that resides in Descartes can potentially only come from a supreme being, which is God; God possess more objective reality than he does formal reality. We as humans, as Descartes states, are finite substance, and God is the only infinite substance. The only way for us as a finite substance to think of an infinite substance is possible if, and only if, there is an infinite substance that grants us the idea of substance in first place. After these smaller arguments, Descartes states that while we can doubt the existence of many things, due to the fact that ...
In the second meditation, Descartes is searching for an Archimedian point on which to seed a pearl of certainty. By doubting everything in his first meditation, Descartes consequently doubts his own existence. It is here that a certainty is unearthed: “If I convinced myself of something then I certainly existed”(17). However, Descartes “does not deduce existence from thought by means of syllogism, but recognizes it as something self-evident by a simple intuition of the mind,” or in other words, by natural light (Second Replies:68).
In his work, Meditations on First Philosophy, Descartes narrates the search for certainty in order to recreate all knowledge. He begins with “radical doubt.” He asks a simple question “Is there any one thing of which we can be absolutely certain?” that provides the main question of his analysis. Proceeding forward, he states that the ground of his foundation is the self – evident knowledge of the “thinking thing,” which he himself is.
Our mind and our body are undoubtedly separate from each other. A mind can survive without a body, and, likewise, a body is just house for the mind. In The Meditations, Descartes describes this concept in his dualist theory in the second of multiple Meditations. We can reach this conclusion by first understanding that the mind can survive any destruction of the body, and then realizing that you are identical to your mind and not your body. In other words, you are your thoughts and experiences – not your physical body. Finally, you cannot doubt your own existence, because the act of doubting is, itself, and act of thinking, and to think is to exist as a “thinking thing,” or Res Cogitans.
In the Third Meditation, Descartes forms a proof for the existence of God. He begins by laying down a foundation for what he claims to know and then offers an explanation for why he previously accepted various ideas but is no longer certain of them. Before he arrives at the concept of God, Descartes categorizes ideas and the possible sources that they originate from. He then distinguishes between the varying degrees of reality that an idea can possess, as well as the cause of an idea. Descartes proceeds to investigate the idea of an infinite being, or God, and how he came to acquire such an idea with more objective reality than he himself has. By ruling out the possibility of this idea being invented or adventitious, Descartes concludes that the idea must be innate. Therefore, God necessarily exists and is responsible for his perception of a thing beyond a finite being.
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.
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 point is not shown clearly, and further, although I can conceive of my own mind existing independently of my body, it does not necessarily exist as so.
Rene Descartes, a 17th century French philosopher believed that the origin of knowledge comes from within the mind, a single indisputable fact to build on that can be gained through individual reflection. His Discourse on Method (1637) and Meditations (1641) contain his important philosophical theories. Intending to extend mathematical method to all areas of human knowledge, Descartes discarded the authoritarian systems of the scholastic philosophers and began with universal doubt. Only one thing cannot be doubted: doubt itself. Therefore, the doubter must exist. This is the kernel of his famous assertion Cogito, ergo sum (I am thinking, therefore I am existing). From this certainty Descartes expanded knowledge, step by step, to admit the existence of God (as the first cause) and the reality of the physical world, which he held to be mechanistic and entirely divorced from the mind; the only connection between the two is the intervention of God.
Through skepticism and doubt Descartes raised a simple yet complex question, what can I be certain of if I doubt everything? Struck by all of the falsehoods he had come to believe, Descartes set out to determine through reason what was certain and able to exist beyond doubt. In order for his habitual opinions and false knowledge to not interfere with his ability to perceive things as they truly were, Descartes doubted everything. In terms of the physical body, our senses tell us that there are external ligaments and matter that come together to produce a body. However, when we are skeptical and doubt all previous knowledge, we are then deceived by our senses and the physical body cannot be proven to exist. Even while doubting the existence of the physical body, Descartes was still able to project skepticism and have thoughts of doubt. There must have been a thinking thing thinking those doubts. For this reason, Descartes concluded that though he may not be certain that the physical body exists, he can be certain that he in fact does exist, “I am, then, in the strict since only a thinking thing that thinks,” (Cottingham 5). Thought has proven to be inseparable from “I” and there must be a self that exists. While nonmaterial, self is the intellect and faculty of thought. “I think, therefore I am,” Descartes concluded to be the single most certain fact and closest statement to an ultimate truth. We can doubt all previous knowledge and beliefs, but we cannot assume that we who are able to have thoughts such as doubts, do not exist.
