Descartes—Meditation III
In Meditation III, Descartes presents his argument for the existence of God. He makes this argument here because it is one of his stronger arguments. In this essay, I will summarize and critically assess this argument.
Descartes begins this meditation with a review of what he is certain of so far. He is skeptical of the existence of bodily things, but s certain that he exists and that he is a thinking thing. He decides that he could not be as certain of his existence unless all clear and distinct perceptions are certain. Therefore, whatever he perceives clearly and distinctly must be true.
Descartes thought he was certain about most things. But skepticism continued to plague him. He seemed to want to escape the problems involved in clear perceptions by relying on God’s existence to make them true.
In Descartes attempt to prove the existence of God, he makes up a theory of ideas. According to him, ideas area small part of thought. All thought is made up of many ideas put together. He suggests that although ideas are images of things, they are not just simple visual representations. We can have ideas of God, of justice, or of how to drive a car. These are ideas, but they are not necessarily images of anything.
Descartes continues to suggest that some ideas are just ideas. He begins to discuss innate, inve...
In Meditations, Descartes brings doubt to everything he believes because it is human nature to believe that which is false. He states that most of what he believes comes from the senses and that a lot of times those senses can be deceived. His conclusion of doubting everything is based on his example of a basket of apples. It goes as follows; you have a basket of apples but you fear that some apples have gone bad and you don't want them to rot the others, so you throw all the apples out of the basket. Now that the basket is empty you examine each apple carefully and return the good apples to the basket. This is what he does with his beliefs, he follows and keeps only those beliefs of which he is sure of. Our beliefs as a whole must be discarded and then each individual belief must be looked at carefully before we can accept it. We must only accept those beliefs we feel are good.
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 starts the meditation by saying what he has already learned in the first two meditations. He states all that he affirms as what he truly knows,
...ples ideas based on the operations of our own mind. For example, the idea of a unicorn is also a complex idea, along with God, while many of us have seen a picture of a unicorn someone had to invent the original idea of what a unicorn is without seeing a picture. The operations of our own mind have created this idea of God, which rebuts Descartes’ argument that we have knowledge on the external world because of God. Descartes would argue that Humes’ idea of God is natural and never derived from impressions. Hume’ consequently has the better argument claiming that idea of god is actually based on ideas of perfection and infinity is inferred from the ideas of imperfection and finitude.
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.
In the face of Rene Descartes extreme doubt, he found that he hoped to use skepticism to find complete certainty. When doubting something, Descartes would start by asking if it is rationally possible to doubt everything. When proceeding to do this, he will find if there is any undoubtedly truth. Instead of Descartes trying to examine every belief that he holds, he examines the origins of different types of beliefs. In doing this, he rejects any idea that could be mistaken, and will reject it right away.
Next, in the fourth meditation, which leads into Descartes’ thoughts on himself in God’s view. It is important to compare to the third meditation. A second point of view of not just an idea, but now Descartes himself. He asks why a perfect being such as God does not make a perfect being like Descartes himself. He questions why he is not perfect in that sense. Then he explains, it would take much arrogance to question the motives of God. Not only that, but it just simply cannot be comprehended. He rejects the trial, and simply believes; since he himself is not perfect, the idea as a whole may be. He is just a part of the “big picture.” He then concludes he should only make judgements on what he is certain of.
The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
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.
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
Descartes emphasizes the idea that his idea of God's existence does not originate from his senses. Rather than having created the idea himself, he states that God himself imprinted the idea on him. “Thus the only option remaining is that this idea is innate in me just as the idea of myself is innate in me” (Descartes, 34). If a person is to believe that innate ideas exist, it follows that the existence of innate ideas is a truth.
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.
Unlike one of empiricism’s major tenets, Tabula Rasa, or blank slate, Descartes believed that the mind was not a blank slate, but actually came pre-loaded, if you will, with ideas, which are part of our rational nature and that our rational nature allows us to grasp . Descartes begins his journey deep within his own mind by claiming that all truths can be conceived by thinking about them. He calls his method cogito or pure reasoning. His famous words “I think, therefore I am,” describes the way that he thinks the mind is the true reality with the rest of reality being an extension. His example to prove thi...
Remember that according to Descartes, what I know first and foremost are my ideas. It is only later that he seeks to know if the extramental world exists, and so he begins with his ideas and then moves towards real being (rather than vice versa). Somewhere along the line the notion of idea undergoes a transformation. Soon an idea becomes a sense impression or an image. Remember that for the Greeks and Mediaeval thinkers, an idea is not reducible to an image. An idea cannot be imagined, but is an essence abstracted from the phantasm and understood. But this gets confused after Descartes. For example, John Locke says that ideas "...stand for whatsoever is the object of the understanding when a man thinks, I have used it to express whatever is meant by phantasm, notion, species, or whatever it is which the mind can be employed about in thinking..."
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.
