Plato And Descartes And Plato's Theory Of Sensory Experience

Improved Essays
Both Plato and Descartes believe that knowledge cannot be gained through sensory experience. Descartes states that the senses may be deceived therefore he must reach knowledge through reasoning. Plato believes that one already has knowledge because the Soul knows the Forms. He thinks that since the Soul holds all knowledge then one must recollect upon the question and the answer will be remembered. Plato uses a slave to prove his “Theory of Recollection”, and, by proxy, his theory of the Forms and the Soul. This, in fact, doesn’t work for he uses his theory of the “all-knowing Soul” to prove that the slave is remembering already learned facts through the “Theory of Recollection” while using the slave to prove his theory of an “all-knowing Soul”. …show more content…
The senses may be deceived so, logically, all things one knows through the senses must be called into doubt. He uses wax to prove that the sensory experience is not knowledge. He takes a block of wax and takes in its characteristics like what it feels, looks, and smells like. Then he puts it near a fire and watches as the wax melts. He then compares the previous characteristics with the new ones. As completely separate objects they share no similarities but Descartes notes that he knows it is the same wax. Therefore, our senses cannot be trusted for they said the same wax was different wax, so Descartes must now doubt all his senses tell him. Descartes goes even further and says that if there is even one reason to doubt something, then he will doubt its certainty. Descartes, through the Method of Doubt, is …show more content…
The “all-knowing Soul” knows the Forms and always will. The Forms themselves are unchanging therefore, they must be true knowledge. Anything less than a Form or concept is only an opinion and subject to change like any sensory experience. This led to the question of finding knowledge. This is where “Meno’s Paradox” comes in, Plato encountered this while trying to define Virtue. When that was unsuccessful he then figured if Virtue was even ‘knowable’ and how one would find it, how does one start looking for something when he doesn’t know what he is truly looking for? If one already knows it, then there is no reason to look for it; but then if one doesn’t know what one is looking for, how will one know they have truly found it. To answer these questions, Plato created the “Theory of Recollection”. To learn what one’s “all-knowing Soul” knows, one must, through careful questions, remember. Plato proves this through the questioning of a slave, who would never normally encounter “complex” math, about a triangle and the relationships of the sides to one another. Originally the slave doesn’t know the answer to the question, he doesn’t remember it, but through careful questioning the slave comes up with the correct answer. Thus, it appears as though he has remembered it. Plato sees this as proof of his theory of an “all-knowing Soul” and the “Theory of

    He says, “ If we do not understand our tools, then there is danger that we will become the tool of our tools ( pg 69).” Here Plato makes its evident that if we do not take advantage of the knowledge and tools that are at our fingertips then we are fools. He is basically saying that what is the point of having all of this knowledge at our disposal if we don’t care to understand where it comes and how to make use of…

    Descartes can demonstrate the validity of his arguments, specifically through the use of the wax example, and ultimately has a larger framework of philosophical reasoning underlying his position than that of Montaigne. Further, Montaigne’s argument is weakened by his initial assumption that all knowledge comes from the senses. Descartes, by finding that the senses can be trusted, defeats this assumption as well as Montaigne’s…

    Plato 's argument of recollection in Meno tries to solve the puzzle of how knowledge is acquired or learned. Plato, a classical Greek philosopher who is a famous writer.

To question is necessary for this ideas of knowledge to be true.…

    Descartes believed that all we can know is information that we are certain of. Knowledge with any amount of skepticism, according to Descartes, proves to be unreliable and thus, not real knowledge. Therefore, he further stated that the knowledge obtained through the senses is not real knowledge because the senses can be deceiving and biased to individuals. Descartes even is skeptical of concepts such as math because he believed that one is just told that two plus three is five, but one cannot be certain. According to Descartes, an "evil genius of the utmost power and cunning has employed all his energies in order to deceive me."…

    He states that the essence of the wax can be known by either: a) the senses or b) the imagination or c) the intellect. To conclude that the essence of the wax is known through the intellect, Descartes must demonstrate that it is not known by the senses or the imagination. Hence, he must present arguments that 1) negate the senses and 2) negate the imagination. Negating Sense: Initially, the wax appears to have features such as colour, taste, smell, size, shape, and solidity.…

    He instead uses these points to show a bigger truth that nothing can be proven with our senses. How can one prove that anything around them is real? Without senses and the knowledge people have been taught over time, there is no way to prove the life around them is real. Descartes argues that nothing is certain without knowledge to back it up. At a time when most philosophers used God to back their…

    The Argument for the Immortality of the Soul When Socrates and Meno are halted in their argument by a paradox, Socrates proposes a new idea that will solve the paradox and continue their conversation. He states that the soul is immortal and it has learned everything in past lives. Thus, what men call learning is actually a process of recollection. I will first be giving context as to how this idea came into the dialogue with Meno. Next, I will explain how he puts the same idea forward in Phaedo and then noting the differences between the two dialogues.…

    In the wax example, Descartes not only shows that perceiving object is considered a node of thinking, but also represent that we can understand an idea through a pure understanding, which is mind rather than sensory experience. The wax significantly suggests that pure understanding is clearer than sensory experience (Descartes, 1996, p20-p21). In the other hand. Locke emphasizes that we understand ideas through primarily using reason which comes from our sensory experience (Locke, 2008, p19). The difference between the two explanations about obtaining true knowledge leads me to think that sensory experiences can be mistaken and as the result, they may cause different people to develop different interpretation on the same idea.…

    In Descartes “Evil Deceiver” argument he argues that an evil demon is the source of our deception rather than an omnipotent God. The strongest argument that Descartes presents is the idea that our senses cannot be trusted as the world around us and everything we experience is a constructed illusion. In this paper, I will argue that this argument can be seen as sound as our senses can not be trusted because they are unreliable. In “Meditation I: What Can be Called Into Doubt” Descartes explains to us that the information we are receiving through our senses isn’t inherently accurate.…

    The purpose of the Theaetetus is to examine how the mind accounts for knowledge by seeking an answer to the question Socrates poses to Theaetetus, what is knowledge? (146A). After a few failed attempts at answering, Theaetetus posits that knowledge is true opinion (187B). Socrates responds that in order for one to know what true opinion is, he must also account for false opinion in the mind. Ultimately, while the dialogue produces no operative definition for knowledge, Plato employs this dialogue to sharpen his arguments for what are and are not the brackets of knowledge.…

    Plato’s Allegory of the cave accounts for his theory of knowledge by showing how leaving ignorance turns perception into true belief. Plato’s theory of knowledge explains that perceptions of things are like the shadows on the cave wall and while the prisoners know a name for the thing, what they see is not true belief. The prisoners however know the names of the perceived things and while their reality is a façade, their soul knows of forms. I will explain how the darkness is ignorance, shadows are perception in the material world, how the prisoners had knowledge to begin with, and how they account for Plato’s epistemology.…

    Descartes believes that the mind and body are separate because people are a rational thinking thing. One needs to think to exist that was the first certainty Descartes came too. Thinking is what makes us exist and the body is simply an extension to that. The body is unnecessary to exist since a person can exist without a leg or an arm but you cannot deceive existence from thinking. Descartes uses the example of the triangle and in class we modified this to say one can imagine a pink triangle since what makes a triangle a triangle doesn’t depend on the color but you can’t imagine a triangle without three sides because that is what makes it what it is.…

    When attempting to solve the problem concerning the immortality of the soul, both Plato and Hume must rely on analogy. Plato, being a rationalist, argues that the soul is immortal and is comparable to a form, for it is invisible and incomposite, unlike material objects. Hume, on the other hand, believes that the soul is mortal and compares souls to perishable objects such as bodies. Although neither analogy can offer any validity, Hume 's argument for the mortality of the soul is far more compelling than Plato 's opposing argument.…
