Descartes’ made himself believe that nothing exists and starts to doubt himself along with the existence of the external world. First, he states that he would never create something that would oppose to another person’s perception. Then goes on to say, that to imagine something it is needed to picture an idea or have a mental picture. Lastly, he brings out the premise that the ideas perceived by what they call senses must come from external soul.
In the first argument, Descartes’ proof of the external world carries a lot of arguments in his perception about what knowledge he has on this world. First, we’re going to introduce the reasons for doubting the existence. Raising the dream argument where we question whether material things exist, he

He says that God can make something that can be perceived in this way and that God is powerful. From that perception you can see that we perceive distinctly when it comes to the world existing or not. God would not create anything that is not perceived distinctly and therefore God would not deceive us. He goes on to say that material objects are corporeal, and they can be observed using sense and when talking about the senses that means that he’s talking about material objects. In the meditations Descartes’ knows that feelings do exist but his doubts, if there is a slight chance of it being false and that is where he tries to prove his knowledge by clearly and distinctly perceptions so that they can be certain that there is existence. Descartes’ argues that the premise in other meditations are evaluating them properly need to have expositions of the arguments because his premises are …show more content…
For that to happen then there needs to be something there. For example, when imaging the world; you must have a picture of the world to even imagine it. Descartes’ defined imagination as “For to anyone paying very close attention to what imagination is, it seems to be simply a certain application of the knowing faculty to a body intimately present to it, and which therefore exists” (AT 8:72). He looks at the difference between imagination and pure understanding. Descartes’ perspective on pure understanding is being capable of understanding material things, while imaginations are from one mind’s eye. To show the difference, he gives a perfect example of the triangle and how it is made up of three lines. Imagining the triangle means having an imagination of the triangle in your head. Whereas a Chiliagon, which is a figure consisting of a thousand sides is hard to just have a picture in your head and imagine. It is more difficult because a chiliagon is not something you can come across in the external world. The idea of imagination on the external world is arguable. Descartes’ finalizes that “At this point I am manifestly aware that I’m in need of a peculiar sort of effort on the part of the mind to understand” (AT 13:73). In relation to this, Descartes’ mentions that imagination is not needed for one person’s mind exists. This means, imagination is connected to something that the mind never thinks about.
Descartes then states that he wishes to extend his knowledge through knowledge in his own self. He judges things that he once knew as fact to possibly now be doubtful and uncertain and that all his prior knowledge could have just been a work from a deceitful God. If then he wishes to learn from within himself and a deceitful God does in fact exist how can he affirm any knowledge within himself or even any knowledge he has affirmed through his meditations? If ideas that he once had now seemed uncertain then does that not mean all he knows can just be a work of a deceitful God, if of course a God does exist.
This idea begins the philosopher’s ongoing discussion on the body and the mind. The first thing he must do is prove he exists beyond a doubt. Descartes declares, “If I convinced myself of something then I certainly existed” (4). This idea rests on the ability of his mind, if he did not actually exist, he would not be have any sort of mental activity. From this early point in the text, Descartes foregrounds the superiority of the mind. As Blackburn puts it, “he is forced to recognize that his knowledge of his self is not based on knowledge of his embodied existence” (20). For Descartes, the ability the think defines the self (the mind/soul)– he cites thought as the one thing that cannot be separated from him. He believes if he stopped thinking he would stop existing. His ability to think sustains him, at this point in his meditations he is only a mind, his mental existence is the only thing he has
He explains the concept of Cartesian body in which he states that there is some connection between mind and body. Mind doesn’t necessarily need any imagination for thinking process but body is somewhere linked to imagination. He explains many links between mind and body. He gives examples like if he feels hungry, his mind would tell his body to eat something. These types of examples make him understand that mind and body works in a parallel way. But mind is distinct from the body, as Descartes’s existence is a thinking thing which is independent of body and Descartes’s body is an extended thing which is independent of mind. So he concludes that he being a thinking thing can exist without a body. But mind and body are combined to form one unit. This leads him to the idea of Cartesian dualism, which is mind-body dualism. If we carefully use our mind, we can avoid judgments which consist of errors. Furthermore, he explains the existence of external material things. He proves it by explaining that he believes in the existence of external material things because of his senses. God has created him with this nature and as God is not a deciever, material things exist and contain the properties necessary for
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...
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 ...
Descartes assured his existence through the conviction of "Cogito, ergo sum" which translates into “I think therefore I am” (Popkin & Stroll 198). In order to question ones existence one must exist, non-existence cannot question itself. I know that my mind exists because I am here to question its existence. To concretize this idea, imagine a house and you are building a house on ground which you see. The house is built out of wood, metal, and earth on the ground. Does the house exist because of the materials used to build it or because your mind tells you that it exists? Well based on Descartes, there are no such things as wood or metal in reality because the only thing that is real is the mind itself and the built house is a figment of your mind to what you perceive as real better known as an illusion. Therefore all that we sense is an illusion and everything outside the mind is uncertain of existence. Furthermore this leads to the ...
“We owe the notion of “the mind” as a separate entity in which “processes” occur to the same period, and especially to Descartes” (Rorty, 2008, p. 234). Plato was the first philosopher to argue that there was something beyond our body. Descartes agree with Plato on this theory and explored this idea more in-depth. Stating that these innate ideas exist, but they remain idle in our minds until a significant event awakens them. He arrived at this idea by doubting everything that he was taught was the truth, and he even doubted his own sense saying that they were deceptive, and after using philosophy of doubt he came to the realization of his existence through the logical reasoning. After he established that his senses were not real, he began to doubt his brain, he stated that our dreams are an interpretation of reality, even though they seem so real. He says that it was only thr...
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)
At the start of the meditation, Descartes begins by rejecting all his beliefs, so that he would not be deceived by any misconceptions from reaching the truth. Descartes acknowledges himself as, “a thing that thinks: that is, a thing that doubts, affirms, denies, understands a few things, is ignorant of many things” He is certain that that he thinks and exists because his knowledge and ideas are both ‘clear and distinct’. Descartes proposes a general rule, “that whatever one perceives very clearly and very distinctly is true” Descartes discovers, “that he can doubt what he clearly and distinctly perceives is true led to the realization that his first immediate priority should be to remove the doubt” because, “no organized body of knowledge is possible unless the doubt is removed” The best probable way to remove the doubt is prove that God exists, that he is not a deceiver and “will always guarantee that any clear and distinct ideas that enter our minds will be true.” Descartes must remove the threat of an invisible demon that inserts ideas and doubts into our minds to fool us , in order to rely on his ‘clear and distinct’ rule.
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).
Descartes thinks that we have a very clear and distinct idea of God. He thinks God must exist and Descartes himself must exist. It is a very different way of thinking shown from the six meditations. Descartes uses ideas, experiments, and “proofs” to try and prove God’s existence.
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.
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’ 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.
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...
