Recommended: John locke vs descartes philosophy

Philosophy is an ever-growing field of study due to the fact that people are constantly yearning to discover the underlying truth in all of life’s matters. Dating back all the way to before the life of Jesus Christ, a great Greek philosopher by the name of Plato, exemplified this nature. He earnestly sought to find the root of true knowledge by using the Divided Line. Plato laid a strong foundation for the future of philosophy and since his time other intelligent philosophers have arose. In the seventeenth century two of the most vital philosophers in all of history came on the scene, René Descartes and John Locke. In attempt to discover how one acquires true knowledge, these two philosophers developed extensive concepts and ideas that greatly …show more content…

He felt that all humans are born with innate knowledge, such as the knowledge of an infinite being, God. An adventitious idea is the thought of actual things that have been experienced such as a table or chair. Descartes believed these were most reliable because they are very clear and distinct. Fictitious ideas are completely made up by use of one’s imagination. Flying horses and ninja turtles are examples of fictitious ideas because they are entirely make believe. After Descartes established that the non-extended mind is most important to allow thinking, he wondered how the mind communicated with the extended body. He came up with what is known as Cartesian Dualism. The Pineal gland, located in the middle of the brain, is the “messenger” between the two. He felt that the mind and soul are inseparable but there must be some form of connection between the mind and the extended …show more content…

Locke was an empiricist and materialist who believed that knowledge comes from experiences and that substances outside of the mind are indeed real. To him, the mind was considered a blank slate or “tabula rasa” at birth and knowledge of the world comes through sensations and reflection. In his essay Locke expresses, “Our observation, employed either about external sensible objects or about the internal operations of our minds perceived and reflected on by ourselves, is that which supplies our understanding with all the materials of thinking.” (Locke 158) Direct sensory experiences and personal memories of past experiences actually make each and every person unique and knowledgeable. Locke believes there are two different ideas to every object, simple ideas and complex ideas. A simple idea is one attribute that aids in making the object what it is. A complex idea is the actual object it’s self; many simple ideas form the complex idea. In addition to Locke’s ideas, he also believes that every object has two types of qualities, primary and secondary. Primary qualities are “in the object” such as figure, motion, or extension. If it was not for these particular qualities, an object could not be known for what it is. Secondary qualities are solely in the perceiver and can change without the object itself changing. Color, sound, and taste

    Locke, an indirect realist, explores our immediate perceptions and with this attempts to draw a line between ideas and qualities, just how these are different entities. Sometimes referred to as Representative Theory, according to Locke, we are aware only of our ideas, these being things existing “in our minds”, sensations created. Our perceptions are indirect and their qualities, these are the causal properties of physical objects that then cause those sensations. This dualistic account

  • Compare And Contrast Locke And Napoleon

    John Locke, Rousseau, and Napoleon all have very different views on what would make a good society. Locke uses a democracy/republican type view that many countries still model after today. Locke’s view on a happy society is the most open and kind to its people, out of the three. Rousseau takes the complete opposite stance from Locke in thinking a more dictatorship government would be what is best for society as a whole as what is good for one person is good for one’s society. Napoleon plays by his own rules with telling people he will follow Lockean like views only to really want to be an absolutist government under his own power. However, all of their ideas would work for a given society so long as they had a set of laws in place and citizens

  • Locke's Theory Of Knowledge By Descartes

    766 Words  | 2 Pages

    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

    The turmoil of the 1600's and the desire for more fair forms of government combined to set the stage for new ideas about sovereignty. Locke wrote many influential political pieces, such as The Second Treatise of Government, which included the proposal for a legislative branch of government that would be selected by the people. Rousseau supported a direct form of democracy in which the people control the sovereignty. (how would the people control the sovereignty??) Sovereignty is the supremacy or authority of rule. Locke and Rousseau both bring up valid points about how a government should be divided and how sovereignty should be addressed.

  • The Rationalism of Descartes and Leibniz

    1674 Words  | 4 Pages

    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...

    ...tina of Sweden persuaded Descartes to go to Stockholm. The Queen insisted on receiving her instruction at 5 a.m. and Descartes broke his lifelong habit of getting up at 11 o'clock. After a few months in the cold northern climate and walking to the palace at 5 a.m., he contracted pneumonia. Within a week, the man who had given direction to mathematics and philosophy had died. By focusing on the problem of true and certain knowledge, Descartes had made epistemology, the question of the relationship between mind and world, the starting point of philosophy. By localizing the soul's contact with body in the pineal gland, Descartes had raised the question of the relationship of mind to the brain and nervous system. Yet at the same time, by drawing a radical distinction between body as extended and mind as pure thought, Descartes had paradoxically created intellectual chaos.

    Our mind then processes that perception into an idea. A great example I can give is from my childhood. I was playing outside by my elderly neighbor and she said, “Stop,” and I did, which made her tell me I was very obedient. I didn’t know what that word meant so I looked it up and did not like the definition. Ever since that day I tried to not be obedient unless I wanted to be or absolutely needed to be. I heard something I didn’t know anything about, researched it and reflected on it and decided I didn’t want to be that. My experience makes me agree with Locke because I was able to process what happened to me and decide for

  • John Locke, George Berkeley and David Hume

    1235 Words  | 3 Pages

    The first philosopher, John Locke, laid the foundations of modern empiricism. Locke is a representational realist who touches reality through feelings. He believes that experience gives us knowledge (ideas) that makes us able to deal with the world external to our minds. His meaning of ideas is "the immediate object of perception, thought, or understanding." Locke's ideas consist of simply ideas which turn into complex ideas. Simple ideas are the thoughts that the mind cannot know an idea that it has not experienced. The two types of simple ideas are; sensation and reflection. Sensation is the idea that we have such qualities as yellow, white, heat, cold, soft, hard, bitter, and sweet. Reflection ideas are gained from our experience of our own mental operations. Complex ideas are combinations of simple ideas that can be handled as joined objects and given their own names. These ideas are manufactured in the human mind by the application of its higher powers. Locke believes in two kinds of qualities that an object must have; primary and secondary. Primary qualities o...

    René Descartes was the 17th century, French philosopher responsible for many well-known philosophical arguments, such as Cartesian dualism. Briefly discussed previously, according to dualism, brains and the bodies are physical things; the mind, which is a nonphysical object, is distinct from both the brain and from all other body parts (Sober 204). Sober makes a point to note Descartes never denied that there are causal interactions between mental and physical aspects (such as medication healing ailments), and this recognition di...

  • Empiricism Versus Rationalism: Descartes and Hume

    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...

    Descartes and Locke both share similar views in their philosophies. They both provide strong evidence to help show what is most real and the secrets of our reality. Locke provides a stronger point of view than Descartes because the evidence in his philosophy goes so far out of his own understanding. Locke has reached deep in the meaning of reality and complexion that with more research we could unlock to true meaning of our ultimate reality. So in comparison between Descartes and Locke, Locke helps explain how we get knowledge, understanding reality, and what is most real.

  • Rene Descartes and the Source of Knowledge

    2129 Words  | 5 Pages

    ...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.
