David Hume And Renee Descartes 's Theories Of Knowledge And Ideas

As humans, where does our knowledge come from? In Meditations on First Philosophy, René Descartes outlines his proof for the existence of God. However, David Hume offers a rebuttal in An Enquiry Concerning Human Understanding that questions not only Descartes’ proof but also his notion of how humans acquire knowledge. In what follows, I will examine Descartes’ proof of God’s existence, then argue that Hume would disagree with it by maintaining that humans can conceive of God through mental processes. Furthermore, I will show how in responding to Descartes' claim that God is the source of our knowledge, Hume asserts that we are instead limited to knowledge from experience.

As a thinking entity, Descartes is a consciousness mind aware of the potential to engage in various modes of existence. To the numerous operations of “thought” he includes doubting, understanding, affirming, denying, willing, refusing, imagining, and sensing. As varied and manifold as these operations appear, they are but expressions of two principal types of conscious activity, to which Descartes eventually traces the nature of error. Thinking and reasoning, together with all belief in general, depend upon the operation of the twin faculties “knowing” and “choosing,” or the free will. Garrett Thompson writes:

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.

René Descartes was a skeptic, and thus he believed that in order for something to be considered a true piece of knowledge, that “knowledge must have a certain stability,” (Cottingham 21). In his work, Meditations on First Philosophy, Descartes concludes that in order to achieve this stability, he must start at the foundations for all of his opinions and find the basis of doubt in each of them. David Hume, however, holds a different position on skepticism in his work An Enquiry concerning Human Understanding, for he criticizes Descartes’ claim because “‘it is impossible,’” (qtd. in Cottingham 35). Both philosophers show distinct reasoning in what skepticism is and how it is useful in finding stability.

Descartes believes that knowledge comes from within the mind, a single indisputable fact to build on that can be gained through individual reflection. While seeking true knowledge, Descartes writes his Six Meditations. In these meditations, Descartes tries to develop a strong foundation, which all knowledge can be built upon. In the First Meditation, Descartes begins developing this foundation through the method of doubt. He casts doubt upon all his previous beliefs, including "matters which are not entirely certain and indubitable [and] those which appear to be manifestly false." (Descartes, p.75, par.3) Once Descartes clears away all beliefs that can be called into doubt, he can then build a strong

Hume's idea on that we derive our ideas through our experiences is very knowledgeable in my opinion. Everyone has different experiences throughout their lives, not everyone's is the same, so we must get our ideas through our experiences. If a little child puts his hand on the hot stove top, hi is in pain from the heat. He will learn from that experience that stoves are hot and not to touch them. Descartes believed that everyone's thoughts and ideas were equal, unlike Hume. How could Descartes idea on equal thoughts be true when not everyone may even have a stove in their house so each little child may not be able to experience the same things?

Descartes defines senses as a part of the process of thinking. He also explains that we can use our senses to help us understand the true nature of things. Descartes struggled with doubt and his senses when he used his ontological proof that God existed. For example, he explains that he is aware that he is not perfect and he makes mistakes. He understands that he must know what perfect is in order to give someone the title. He knew that something perfect lead him to have these ideas and that it must exist. His definition of perfect is unique without the knowledge of anyone else and he defined it as God. For example, Descartes believes that God is perfect and deception is a sign of imperfection. Therefore, Descartes came to the conclusion that God cannot deceive. This example shows that Descartes did struggle to accept his own belief without doubting himself. His ontological argument proved, to Descartes, that through God everything

exists and his idea of what a perfect being is, such as God, then God exists.

Descartes' meditations are created in pursuit of certainty, or true knowledge. He cannot assume that what he has learned is necessarily true, because he is unsure of the accuracy of its initial source. In order to purge himself of all information that is possibly wrong, he subjects his knowledge to methodic doubt. This results in a (theoretical) doubt of everything he knows. Anything, he reasons, that can sustain such serious doubt must be unquestionable truth, and knowledge can then be built from that base. Eventually, Descartes doubts everything. But by doubting, he must exist, hence his "Cogito ergo sum".

This essay attempts to explain Descartes’ epistemology of his knowledge, his “Cogito, Ergo Sum” concept (found in the Meditations), and why he used it [the cogito concept] as a foundation when building his structure of knowledge. After explaining the concept I give a brief evaluation of his success in introducing and using this cogito as a foundation. Finally, I provide reasons why I think Descartes succeeded in his epistemology.

With the emergence of the scientific revolution in the 17th century, views of society and nature were transformed throughout Europe. There were great developments in mathematics, physics, astronomy, biology, and chemistry. The world and its views were changing, and with that change, came a new change in thought, a new change in philosophy. Apart from ancient Greek philosophy, which was centered on finding order in a vast variety of things by searching for a fundamental amalgamating principle, Descartes sought to establish order via some fundamental division. Descartes understands and expresses that what we know about our mind is more definite than what we know about the world outside our mind. Descartes’

     Knowledge is gained only through experience, and experiences only exist in the mind as individual units of thought. This theory of knowledge belonged to David Hume, a Scottish philosopher. Hume was born on April 26, 1711, as his family’s second son. His father died when he was an infant and left his mother to care for him, his older brother, and his sister. David Hume passed through ordinary classes with great success, and found an early love for literature. He lived on his family’s estate, Ninewells, near Edinburgh. Throughout his life, literature consumed his thoughts, and his life is little more than his works. By the age of 40, David Hume had been employed twice and had failed at the family careers,

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

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.
