The Pros And Cons Of Epistemology And Theory Of Knowledge

Kant credited both empiricism and rationalism movements. He believes that they both contributed to human’s knowledge and should not reject neither one of them. So, he keeps some parts of those principles and defines empiricism a posteriori knowledge and rationalism as a priori knowledge. His goal is to explain and then justify the possibility of scientific knowledge.

In order to understand Descartes’ way of thinking, it is crucial to note his education. He received a sufficient education in mathematics and science which led to his rejection of scholastic philosophy. He was not only taught about old philosophers such as Plato and Epictetus, but there was a recent philosopher [according to his time] named Montaigne who was a

In Meditations on First Philosophy, René Descartes philosophies made a substantial advancement in enabling us to understand the world around us by querying many of the Aristotelian doctrines that are still being discussed in philosophy today. He attempts to answer the question; can you fully trust your senses? Descartes uses methodological doubt, which is a process of being skeptical about truths of someone’s belief to revoke from his senses. In Meditation One: Concerning Those Things That Can Be Called into Doubt, he argues that people cannot rely on their senses for full truths. Descartes says we must question everything and doubt everything because everything in this world is subjective as opposed to objective. He begins to argue by saying how when he was a child he believed certain things to be true but then later found out the real truth. Within his first meditation he uses an example of dreaming to prove how our senses deceive us. In Meditation Two: Concerning the Nature of the Human Mind: That the Mind is More Known Than the Body, Descartes starts off by questioning God and Heaven and provides another example of the ball of wax to support his ideas of how our senses cannot be fully trusted. Descartes does a fantastic job proving that the mind and body are disconnected and therefore we cannot trust our senses.

Rationalism is an explanation of the world through our minds. Rationalism is a theory of knowledge where the critical

Rationalism: a belief or theory that opinions and actions should be based on reason and knowledge rather than on religious belief or emotional response.

Descartes is able to examine ideas and gain knowledge form them. Innate ideas mean they are present at birth, in other words we are implanted with certain ideas at our creation. He often uses ‘innate ideas’ to explain the mind’s original programming. “An infant’s mind is programmed with the rules of logic. Consider as an example the valid rule, modus ponens. Let P and Q stand for variables… the rules states that, if P then Q is true and P is true, then it follows that Q is true. We know that we are programmed with this rule because young children, who have never studied logic and have never entertained the rule, when given an argument in which the variables above are replaced by actual sentences, are able to intuit the validity of the argument.” Descartes believed our minds are programmed with eternal truths, “Whatever comes into existence must have been brought into existence by something else.” He also discovers that the idea of God is only part of his initial programming but also that God, operating through secondary sources such as his parents, is the programmer.

In Descartes Objection and Replies the idea of knowledge, how it is gained and defined, and the idea of true intellect are discussed. Through the use of the wax experiment true intellect is found, defined, and explained. With this being said he wanted to demonstrate how none of the truths we found through basic perceptive tools or senses can be relied upon and that you had to utilize deep though or knowledge to know how something is defined or even if it exists.

Descartes as a rationalist believes that knowledge comes from the mind alone. During the First Meditation, Descartes came to the conclusion that there must be some kind of evil deceiver that "leads him to a state of doubt" (Descartes 77). Descartes starts out with the fact that distant sensations are subject to doubt and uncertainty. He then goes on to try and cast doubt onto close sensations. Descartes starts off by stating that close sense perception must be certain because we are not crazy, and only a insane person would doubt what was right in front of them. Descartes then uses the dream argument to cast uncertainty on close sense perception because "they are as lively, vivid and clear as reality is when we are awake" (Descartes 76). Descartes then states that geometry and math are certain. "For whether I am awake or sleeping, two and three added together always make five, and a square never has more than four sides; and it does not seem possible that truths so apparent can be suspected of any falsity or uncertainty" (Descartes 98). Descartes comes to realize this certainty because math, geometry, and the simple sciences can be understood and proved through logic and reasoning. He then uses his Deceiver Argument to cast doubt on close sensations. He questions how we know for certain that God is good, and how we know that

He finds it plausible that we are all living in a dream and we have never experienced reality. He can no longer give any credence to his senses and finds himself in a place of complete uncertainty. Descartes comes to the conclusion that nothing can be perceived more easily and more evidently than his own mind. He has discovered that even bodies are not accurately perceived by the senses or the faculty of imagination, and are only accurately being perceived by the intellect. He also realizes that they are not distinguished through being touched, smelled, or tasted, but by being understood alone. (An apple is an apple because our mind tells us that it is an apple.) It is the faculty of reason that gives the knowledge and lets the mind know the truths and essences of objects. Descartes assumes that all of us can be decided by our senses, someone can see something far away, and then discover that is not what we thought it was. Or even a oar when is immerse half in water attempt to be bent, but instead is straight. Descartes think that we cannot always be sure of what we sense, and gives the example of himself seated by the fire.

Secondly, Descartes, by embarking on this reconstruction of his thoughts, hopes to find a stable basis for the sciences. Since Descartes was trained as a mathematician, he likes to find proofs for ideas, so that he can know them with absolute certainty. Initially, he believes philosophy to be the basis for the sciences “insofar as they [the sciences] borrow their principles from philosophy.” However, he concludes that philosophy cannot be the basis for the sciences, saying, “one could not have built anything upon such unstable foundations.” Now, he has to find a stronger foundation for the sciences and it is only through the reconstruction of his thought that he is able to do this.

     Through his philosophical search Descartes was able to find one indubitable certainty, that we are thinking beings. We always think, even when we have doubts that we are thinking we are still thinking because a doubt is a thought. Although Descartes found this one universal truth, he was still not able to believe in anything but the fact that he was a thinking being. Therefore he still doubted everything around him. He used this one certainty to try to find a system of knowledge about everything in the world. Descartes idea was to propose a hypothesis about something. For example he might say that a perfect being was in existence. He would go around this thought in a methodical way, doubting it, all the while trying to identify it as a certainty. Doubting everything was at first dangerous because in doubting everything he was also admitting that he doubted the existence of God, and thus opposing the church. However he made it a point to tell us at the beginning of his Discourse on Methods that what he was writing was only for himself and that he expected no one but himself to follow it (Descartes 14, 15). Descartes eventually managed to prove the existence of a higher being. He said that since he had the idea of a perfect being, then that perfect being must exist. His

Descartes’s theory of knowledge is essentially based in skepticism. He argued that in order to understand the world, first a person has to completely suspend their judgements of the world around them. This is the impression that the world makes on their mind. In this way, the physical world is not what leads to knowledge. Instead, the mind finds rationally seeks knowledge. The question is, essentially, “should we believe beyond the evidence?” (Kessler, 2013, p. 332). In this way, the ideas are rooted in the nature of doubt. This is an inherent nature of the mind, which is the result of the nature of man as made by God. In this way, the mind is guided by god towards knowledge in its infallible ability to reason about reality. In this way, the mind’s reasoning ability, even in the absence of physical reality, can ultimately lead to knowledge. I don’t fully agree with Descartes’ proposition that only the mind can produce certain knowledge and that our senses are constantly under the attack and being deceive by some evil deceiver. In order to go against Descartes propositions concerning about doubt I will use Locke to oppose it.

Renee Descartes, as a Rationalist viewed knowledge as something that we achieve through reason. Descartes begins his theory of knowledge by assuming that nothing exists. By doing this he would have to trust nothing. Not his senses, not anything that he has thought. As a Rationalist he sought to eliminate all doubt and anything else that wasn 't completely credible. Because he found that his senses were not one hundred percent reliable, as he found they sometimes deceived him, he did not trust them. Descartes believed that in order to obtain knowledge, there must be a rational method for obtaining it, and that the use of the senses, or any personal experience was not a reliable source. Finally, in Meditations on First Philosophy he concludes that he is a thinking thing: “I think, therefore I am”. He knows that this is true because he thinks, and to disprove that would require thinking and since he

Descartes is a rationalist about knowledge, so that means he believes that it is possible to gain knowledge through our mind and that we have the ability to know things that we have never seen or experienced before.(Descartes, 1641) He believes that everyone is born with the inherent ability to know two things; mathematics and God. He argues that we have the ability to infer mathematic skills from our minds. (Pismenny, 2016) He also says that we are born with the idea of God and religion already in our minds and that God is responsible for

Firstly, Descartes deals with the issue of empiricism- the theory that our knowledge is derived from our sensory experiences. Since we know from everyday errors that our senses have the ability to deceive us fairly often so making our perceptions to be something that it is not. For example, there are lots of examples of optical illusions and the fact that the train tracks may appear to converge from a distance. Consequently, we ought to
