Descartes: Knowledge is Truth
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’ philosophy is completely different from that of the Greeks, where it is not about a fundamental principle, but about a fundamental knowledge.
Descartes’ examination of knowledge and where it comes from ultimately leads him to a new belief on how knowledge is acquired. Apart from previous beliefs, that knowledge comes to us through sense perception, Descartes argues that this is not the case, as instead knowledge comes to us only through applying pure reason. Descartes dismisses the notion that our senses give us knowledge because to Descartes our senses give us accidental qualities of things. In other words, we see, hear, feel, smell, and taste things the way “they are” in relation to our human body. Our senses are different than those of other animals; therefore we cannot fully rely on our senses to give us the information we need. Descartes’ famous saying, “cogito ergo sum,” is a conclusion that he reached “a priori” and not through his senses or experience. For Descartes this was an essential p...

...or humans to benefit from it. We benefit from nature by using the applied sciences, such as medicine and mechanics. Each applied science has a set of moral principles, which stem from the “tree of knowledge.” With knowledge and our acquisition of it, our place in the cosmos changes from person to person. My view is unique, and after reading Descartes, it has changed. I have a new found knowledge after reading Descartes, and now I have a different understanding of “the truth” of the cosmos and my place in it.

Review of Descartes: An Intellectual Biography and Descartes' Error: Emotion, Reason, and the Human Brain
Descartes asserts knowledge is done through experimentation using a scientifc method to removing opinions, and come up with a solution to conflicts. In the Discourse on Method, Descartes describes his unique style of reasoning, and makes clear that his main goal for writing is to solve epistemology, or the theory of knowledge. Similar to Socrates, Descartes sensory perceptions cause a false belief in the world around us, he believes one needs to be thinking on the intelligible level, however Descartes provides a different method to achieving this goal.
RENÉ DESCARTES by career being a Mathematician carried his interest of entering into the philosophy realm. At a very young stage, he decided that nature is to be explained with certainty as Mathematics. Mathematics in itself is very numerical, where the nature cannot be expressed numerically but is bound in a neat and clear cut way. Thus, his philosophy about everything in nature is very mechanical and machine-like.
In his work, Meditations on First Philosophy, Descartes narrates the search for certainty in order to recreate all knowledge. He begins with “radical doubt.” He asks a simple question “Is there any one thing of which we can be absolutely certain?” that provides the main question of his analysis. Proceeding forward, he states that the ground of his foundation is the self – evident knowledge of the “thinking thing,” which he himself is. Moving up the tower of certainty, he focuses on those ideas that can be supported by his original foundation. In such a way, Descartes’s goal is to establish all of human knowledge of firm foundations. Thus, Descartes gains this knowledge from the natural light by using it to reference his main claims, specifically
Descartes argues in favor of human reasoning, involving innate ideas and subsequent deductions, as the sole avenue toward reaching this certain knowledge. On the other hand, Locke does not invest himself in the possibility of achieving any knowledge that can be claimed as a universal truth. Rather than this, Locke favored the idea that experience can lead individuals to knowledge that is most probable. Ultimately, these two philosophies cannot reconcile themselves together because of a core divergence on the question of the origins of knowledge. As Locke’s argument finds itself dependent on the concept of the mind as a “tabula rasa” at birth, this doctrine surpasses Descartes’ assertion of innate knowledge and, by extension, systematic doubt. For readers, the acceptance of the mind as a blank slate invariably leads to an acceptance of Locke’s reasoning above Descartes’. The argument propelling Locke’s essay and the improbability of innate knowledge favors the idea that there can be no universal truths and that, since individuals are born without any truths evident to them, they must depend entirely on sensory perception of the external world on which to base the beginnings of their knowledge. To support this, Locke considers how children gain knowledge of the world in small increments, as opposed to possessing an extensive knowledge from the time of their birth. Locke discusses that an individual with exposure solely to black and white would be absolutely unaware of scarlet or green, just like children are ignorant of the taste or texture of pineapples and oysters until they first taste
Not only did Descartes set aside all of his previous knowledge, but he also set aside all knowledge he had gained, and that he continued to gain from his five senses. He would not believe what his eyes saw, or what his hand felt, because he could not yet determine his senses as giving him knowledge that could be turned into certainties. He did not have any reason to believe that he could rely on his senses. Descartes doubting of his senses also caused him to reject any knowledge that he had gained through life experience. Most of the knowl...
“Cogito ergo sum - I think therefore I am.” A mathematician, scientific thinker, and metaphysician Rene Descartes used this term in his “Meditation on First Philosophy.” This term has become famous especially in western philosophy. However, this term was not Descartes only legacy. His legacies include the development of the Cartesian coordinates, philosophical books, and theories. Even though the distinction between mind and body can be traced to the Greeks, Descartes account of the mind and body relationship has been considered the first and the most influential. Descartes was born in 1596 in France, from 1628 to 1649 Descartes remained in Holland, during this time he composed multiple works that set the scene for all later philosophical study of mind and body. (René Descartes and the legacy of mind/body dualism) “Meditation on First Philosophy,” is one of Descartes famous treatises. First published in the 17th century, it consists of six meditations. In the first meditation Descartes eliminates all belief in things that are not certain, basically he removes everything from the table. Then one by one he examines each belief and determines whether any of these beliefs can be known for sure. Meditations three and five focus on the existence of God. This ontological argument is both fascinating and poorly understood in the philosophical community. Descartes tries to prove God’s existence by using simple but influential foundations. (Nolan). Descartes innate ideas proof and ontological proof of the existence of God is going to be assessed through the summarization of meditation thee and meditation five, while his work is also going to be compared to Anselm’s ontological argument on the existence of God.
Although philosophy rarely alters its direction and mood with sudden swings, there are times when its new concerns and emphases clearly separate it from its immediate past. Such was the case with seventeenth-century Continental rationalism, whose founder was Rene Descartes and whose new program initiated what is called modern philosophy. In a sense, much of what the Continental rationalists set out to do had already been attempted by the medieval philosophers and by Bacon and Hobbes. But Descartes and Leibniz fashioned a new ideal for philosophy. Influenced by the progress and success of science and mathematics, their new program was an attempt to provide philosophy with the exactness of mathematics. They set out to formulate clear and rational principles that could be organized into a system of truths from which accurate information about the world could be deduced. Their emphasis was upon the rational ability of the human mind, which they now considered the source of truth both about man and about the world. Even though they did not reject the claims of religion, they did consider philosophical reasoning something different than supernatural revelation. They saw little value in feeling and enthusiasm as means for discovering truth, but they did believe that the mind of an individual is structured in such a way that simply by operating according to the appropriate method it can discover the nature of the universe. The rationalists assumed that what they could think clearly with their minds did in fact exist in the world outside their minds. Descartes and Leibniz even argued that certain ideas are innate in the human mind, that, given the proper occasion, experience would cause...
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
Rene Descartes decision to shatter the molds of traditional thinking is still talked about today. He is regarded as an influential abstract thinker; and some of his main ideas are still talked about by philosophers all over the world. While he wrote the "Meditations", he secluded himself from the outside world for a length of time, basically tore up his conventional thinking; and tried to come to some conclusion as to what was actually true and existing. In order to show that the sciences rest on firm foundations and that these foundations lay in the mind and not the senses, Descartes must begin by bringing into doubt all the beliefs that come to him by the senses. This is done in the first of six different steps that he named "Meditations" because of the state of mind he was in while he was contemplating all these different ideas. His six meditations are "One:Concerning those things that can be called into doubt", "Two:Concerning the Nature of the Human mind: that it is better known than the Body", "Three: Concerning God, that he exists", "Four: Concerning the True and the False", "Five: Concerning the Essence of Material things, and again concerning God, that he exists" and finally "Six: Concerning the Existence of Material things, and the real distinction between Mind and Body". Although all of these meditations are relevant and necessary to understand the complete work as a whole, the focus of this paper will be the first meditation.
Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.
Rene Descartes’ natural light is his saving grace, and not Achilles’ heel. Descartes incorporates the concept of natural light within his epistemology in order to establish the possibility of knowing things completely without doubt. In fact whatever is revealed to the meditator via the natural light is considered to be indefeasible. The warrant for the truth of these ideas does not rely on experience or the senses. Rather the truth of the idea depends on viewing the concept through clear and distinct perception. Descartes’ “I am, I exist”, (Med. 2, AT 7:25) or the ‘cogito’ is meant to serve as the basis for knowing things through clear and distinct perception. Descartes’ cogito is the first item of knowledge, although one may doubt such things as the existence of the body, one cannot doubt their ability to think. This is demonstrated in that by attempting to doubt one’s ability to think, one is engaging in the action of thought, thus proving that thinking is immune to doubt. With this first item of knowledge Descartes can proceed with his discussion of the possibility of unshakeable knowledge. However, Descartes runs into some difficulty when natural light collides with the possibility of an evil genie bent on deceiving the meditator thus putting once thought concrete truths into doubt. Through an analysis of the concept of natural light I
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...
...ll true knowledge is solely knowledge of the self, its existence, and relation to reality. René Descartes' approach to the theory of knowledge plays a prominent role in shaping the agenda of early modern philosophy. It continues to affect (some would say "infect") the way problems in epistemology are conceived today. Students of philosophy (in his own day, and in the history since) have found the distinctive features of his epistemology to be at once attractive and troubling; features such as the emphasis on method, the role of epistemic foundations, the conception of the doubtful as contrasting with the warranted, the skeptical arguments of the First Meditation, and the cogito ergo sum--to mention just a few that we shall consider. Depending on context, Descartes thinks that different standards of warrant are appropriate. The context for which he is most famous, and on which the present treatment will focus, is that of investigating First Philosophy. The first-ness of First Philosophy is (as Descartes conceives it) one of epistemic priority, referring to the matters one must "first" confront if one is to succeed in acquiring systematic and expansive knowledge.
