Doctrine is a topic that can take many turns and turns before it finds an reply to a general inquiry. Sometimes, an reply is still left unfound. Doctrine, in its broadest footings, can be described as the systematic chase of cognition and human excellence. What we are concerned with is cognition. Many people have theories of cognition. Amongst them, there are two we will be looking at, Descartes and Plato. We will analyze Descartes? epistemology in Meditations on First Philosophy and Plato? s in The Republic.

Descartes? epistemology is known as foundationalism. In the Meditations, Descartes doubts everything he was taught to believe because it is human inclination to believe what is false. In the first, he claims that most of what he believes is from his senses and that those senses are sometimes deceived. His solution to doubting everything is compared to a basket of apples. You fear that some apples have gone bad and you don? T want the others to decompose, so you throw all the apples out of the basket. Once this is done, you examine each one and return the good apples to the basket. This is what he does with his beliefs. He keeps merely those he is certain of. We must fling our beliefs as a whole and so analyze each one separately. We must construct on the good beliefs. Descartes, nevertheless, does recognize we can? t throw every belief out because they are a portion of us, unlike the apples. We would hold no footing for retrieving any of our beliefs. We would be unable to warrant anything. No belief based on sense-perception is free from uncertainty. He said it is possible that his life is all a dream and he is being deceived into believing it is world. He besides holds false anything that is physical exists, including his ain organic structure. The lone things we should swear are those beliefs that are capable to rational examination. We must besides declare our mathematical judgements to be false besides because an evil devil might be lead oning us. Now, Descartes has cast uncertainty on all his beliefs about everything but himself. He can non be deceived about himself. It is on himself that he will be able to reconstruct his cognition of other things. If he had no cognition of himself, so nil can be certain. If he doubts, he must be an bing ego which is engaged in doubting. If he doubts, he must besides be believing and Descartes said & # 8221 ; I think, therefore I am. & # 8221 ; He must besides be so that he can be deceived. If he is woolgathering, so he is besides believing, therefore he still exists. This is the first measure to geting cognition, to Descartes. You must construct on what you know is certain, get downing with yourself as the foundation.

In the 2nd speculation, Descartes attempts to demo we know organic structures through ground and non through senses. He uses a piece of wax to show. Over a period of clip, a newly produced piece of wax placed by the fire loses or changes all its specific belongingss, yet it is known to be the same object. Its gustatory sensation and olfactory property disappear. Its colour, size, and form are wholly transformed. It loses its hardness and coldness to liquidness and heat. To cognize the wax, you must be able to expect its alterations. Descartes argues, though, that the imaginativeness could non perchance calculate out all conditions, for they are infinite. One can merely cognize an object through apprehension, instead than through images, esthesis or imaginativeness. He now has knowledge about himself and any object that he has thought about through ground. We are now traveling along nicely in reconstructing our house of cognition.

In the 3rd speculation, we move into another edifice block of cognition, God. We look at the illustration of two plus three bing five. We see this to be clear and distinguishable, but it is possible that we are being deceived. He tries to chase away the uncertainty about propositions of mathematics by claiming that God exists and would non let such a misrepresentation. He makes an statement for God? s being. Premise one provinces that we have an thought of God. Premise two provinces that the lone manner to hold an thought of God is if God exists. Therefore, the decision is that God exists. Us holding an thought of God means us holding an apprehension of the space. We can? t understand the space through the finite, but merely through the space, therefore God must besides be the cause of the thought of God. We as finite substances can non do the being of an infinite substance. The thought is besides an nonsubjective world, therefore it can be held as true. God is non lead oning us and now we have added the concluding edifice block to our house of cognition.

In The Republic, Plato has his ain epistemology. His is more along the lines of idealism. The acclivity to knowledge is non based upon understanding an object, but understanding the thought of that object. The highest thought or signifier is the thought of the Good itself. Socrates is the chief character of this subdivision of The Republic. He engages in a conversation with Glaucon about cognition. Socrates gives two images of the ascen

T from helter-skelter sentiment to orderly knowledge, the image of the divided line and of the Cave. Knowledge is what is certain and true and sentiment is what is fallible. This is where we may see a connexion between Plato and Descartes. They both agree that cognition must be certain and all other things false.

Plato held that all cognition can be derived from a individual set of rules. Knowledge rests on the Good as its foundation, unlike Descartes, where one? s ego is the foundation. Plato compares the power of the Good to the power of the Sun. The Sun illuminates things and makes them seeable to the oculus. The absolute good illuminates things of the head and makes them apprehensible. Harmonizing to Plato, the thought of the Good is excessively much for worlds to understand, but can be thought of as the thought of absolute order. The Sun is the cause of coevals, nourishment, growing, and visibleness. The Good is the cause of kernels, constructions, signifiers, and cognition. This is slightly similar to Descartes because God is the cause of the thought of Himself, therefore the cause of everything else besides.

There are four degrees of cognition. First, there are two governing powers though. The good is set over the rational universe and the Sun over the seeable universe. We start with two lines, one for cognition and one for sentiment. Now we cut them one time more and now there are four subdivisions, two belonging to the apprehensible universe and two belonging to the seeable universe, two belonging to knowledge and two belonging to sentiment. The first subdivision is that of images such as shadows and contemplations. The 2nd trades with us seeing existent things, sense-perception. Unlike Descartes, we will non fling this, but use it to construct on our cognition. Descartes believes sense-perception to be false, but Plato uses it as a stepping rock towards cognition. Now we have the two subdivisions of the rational. The 3rd subdivision is where the psyche has understanding through its premises based on images. The 4th subdivision is where the psyche moves past the usage of any images and purely grounds things out. One does non utilize objects, but thoughts to ground.

Following is the Allegory of the Cave. Plato? s fable is a transcript of the world of the divided line. Plato realizes people can believe and talk without being cognizant of the Forms. Plato treats these people as captives chained in a cave, unable to turn their caputs. All they are able to see is the wall of the cave and a fire Burnss behind them. There is a topographic point to walk between the captives and the fire. There are others in that topographic point that hold up objects to project shadows on the wall of the cave. The captives are unable to see these objects behind them. They see and hear merely the shadows and reverberations cast by these objects. Prisoners like these would misidentify visual aspect for world. They would believe the shadows are existent, but would be incognizant of the causes. Plato points out that they would mention to the shadow instead than the existent object. The lone manner for the captive to see what he is speaking approximately is to turn his caput about. We really name things we can non see, but things that we can merely hold on in the head. When the captives are released, they can see the existent objects and recognize their mistake. The manner we can see the causes of our shadows is by hold oning the Forms with our heads. The captives now ascend upwards out of the cave ( into the rational universe ) . When they foremost leave the cave, their eyes experience pain the same manner the jury that convicted Socrates felt hurting. They were non used to the light merely like the jury was non used to Socrates? mode of speech production. The captives would, at first, respond violently as the jury did and seek to fall back into the cave. This is similar to when the jury sentenced Socrates to decease. But the captives must travel on. Once they adjust, they are able to see the objects and what they must possess in itself. This takes us back to Descartes once more. Descartes besides believed we must look for an object? s singularity without trusting on sense-perception. The visible radiation shows them what the external conditions must be and so they eventually see the Sun, the beginning of the external status.

Plato and Descartes have their ain epistemologies. Plato? s is that of Idealism and Descartes? is Foundationalism. They differ slightly while they besides portion similarities. Plato says what we see are shadows, non the existent objects. A philosopher is one who strives to see the object and what makes the object unique. Finally, the philosopher will be able to see the thought of the object. Descartes besides aims to happen the singularity of an object and the thought of it through ground, but his attack differs. He casts uncertainty on what he feels International Relations and Security Network? T certain and starts to reconstruct his house of cognition on what is, himself being the foundation. Plato is non needfully looking to project uncertainties on one? s beliefs, but is seeking to spread out one? s cognition of it. Their terminals are the same, seek to make the Good or God, but their agencies are different.
