Recommended: David Hume's epistemology
I do believe there is an objective reality. Because things stay the same; there is a world that we live in which trees are trees and a table is a table. I believe that because we experience things, it means that they exist. My view is that Hume is correct, because Hume says we cannot successfully imagine things that we do not experience and he explains that the continuity of perception supports objective reality. However, I will also discuss Locke and Berkeley and the flaws surrounding their explanations of the real world. George Berkeley, John Locke, and David Hume are empiricist who believed that knowledge came from experience, not pure reason. All we know in this world is whatever we are experiencing. But granted this fact, they still had …show more content…
He believed that the mind is a blank sheet and that knowledge comes to us through our senses. His idea of reality was that it was divided up into two categories: primary and secondary qualities. When these objects are in motion, the two properties fuse together. His theory says that the primary qualities are the objective reality and the secondary qualities are the things we experience that allow us to interact with the object. Primary qualities are mind-independent qualities that the physical object themselves have and usually stay the same. For example, mass, density, and weight. They’re not in our minds, they are in the external world. Secondary qualities, according to Locke, are not objectively real and can only be subjectively perceived. These include color, taste, and smell. Secondary qualities appear different at different times and to different people. For example, if a person who has had their hand on the stove puts their hand in room temperature water, the water would feel cool. On the other hand, if another person had their hand in the freezer and put that hand in the same room temperature water, it would feel warm to them. How could the water be both warm and cool at the same time? This shows that secondary qualities are mind dependent because the hotness or coldness does not exist in the water, but rather it is a sensation in our minds produced by the primary qualities of the water. He still believes in an external world. He believes that primary qualities exist external to our
Hume's analyses of human apprehension and of causality were the most penetrating up to his time and continue to have great influence. Contemporary Spanish philosopher Xavier Zubiri (1893-1983) has examined both and identified three underlying errors: (1) the failure to recognize that there are three stages of human intellection, and especially that the first, primordial apprehension, has quite unique characteristics; (2) the attempt to place an excessive burden on the content of impressions while ignoring what Zubiri terms their 'formality of reality'; and (3) the failure to recognize that functionality, not causality, is the basis for most of our knowledge. Causal chains in general cannot be adequately known, and therefore are not and cannot be the basis of our knowledge of the external world. Only in the area of persons and morality does causality play a critical role.
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
Megan Darnley PHIL-283 May 5, 2014 Compatibilism and Hume. The choices an individual makes are often believed to be by their own doing; there is nothing forcing one action to be done in lieu of another, and the responsibility of one’s actions is on him alone. This idea of Free Will, supported by libertarians and is the belief one is entirely responsible for their own actions, is challenged by necessity, otherwise known as determinism. Those championing determinism argue every action and event is because of some prior cause.
In An Inquiry Concerning Human Understanding, David Hume demonstrates how there is no way to rationally make any claims about future occurrences. According to Hume knowledge of matters of fact come from previous experience. From building on this rationale, Hume goes on to prove how, as humans we can only make inferences on what will happen in the future, based on our experiences of the past. But he points out that we are incorrect to believe that we are justified in using our experience of the past as a means of evidence of what will happen in the future. Since we have only experience of the past, we can only offer propositions of the future. Hume classifies human into two categories; “Relations of Ideas,” and “Matters of Fact.” (240) “Relations of ideas” are either intuitively or demonstratively certain, such as in Mathematics (240). It can be affirmed that 2 + 2 equals 4, according to Hume’s “relations of ideas.” “Matters of fact” on the other hand are not ascertained in the same manner as “Relations of Ideas.” The ideas that are directly caused by impressions are called "matters of fact". With “matters of fact,” there is no certainty in establishing evidence of truth since every contradiction is possible. Hume uses the example of the sun rising in the future to demonstrate how as humans, we are unjustified in making predictions of the future based on past occurrences. As humans, we tend to use the principle of induction to predict what will occur in the future. Out of habit, we assume that sun will rise every day, like it has done in the past, but we have no basis of actual truth to make this justification. By claiming that the sun will rise tomorrow according to Hume is not false, nor is it true. Hume illustrates that “the contrary of every matter of fact is still possible, because it can never imply a contradiction and is conceived by the mind with the same facility and distinctness as if ever so conformable to reality” (240). Just because the sun has risen in the past does not serve as evidence for the future. Thus, according to Hume, we are only accurate in saying that there is a fifty- percent chance that the sun will rise tomorrow. Hume felt that all reasoning concerning matter of fact seemed to be founded on the relation between cause and effect.
Cause and effect is a tool used to link happenings together and create some sort of explanation. Hume lists the “three principles of connexion among ideas” to show the different ways ideas can be associated with one another (14). The principles are resemblance, contiguity, and cause and effect. The focus of much of An Enquiry Concerning Human Understanding falls upon the third listed principle. In Section I, Hume emphasizes the need to uncover the truths about the human mind, even though the process may be strenuous and fatiguing. While the principle of cause and effect is something utilized so often, Hume claims that what we conclude through this process cannot be attributed to reason or understanding and instead must be attributed to custom of habit.
One of Locke’s largest points is "All ideas come from sensation or reflection” (Locke 101). He thinks that man is completely blank when they are born and that their basic senses are what gives them knowledge. Locke states, “Let us then suppose the mind to be, as we say, white paper” (Locke 101). Locke is basically saying that human nature is like a blank slate, and how men experience life in their own ways is what makes them good or evil. Overall, Locke believes that any and all knowledge is only gained through life
Locke feels that we do not have any innate ideas. Then the question arises of
I will argue that Locke believed that if you remain the same person, there are various entities contained in my body and soul composite that do not remain the same over time, or that we can conceive them changing. These entities are matter, organism (human), person (rational consciousness and memory), and the soul (immaterial thinking substance). This is a intuitive interpretation that creates many questions and problems. I will evaluate Locke's view by explaining what is and what forms personal identity, and then explaining how these changes do conceivably occur while a human remains the same person.
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
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...
As Locke advances into his reasoning, he expands on the definition of a person, as beings that are able to rationalize, perceive, and contemplate. These are all faculties that are in fact “conscious” or in other words, things that we are self- aware of. A person is aware of themselves as well as their surroundings, which they are able to perceive through their senses and from there, they are able to internally rationalize, think and interpret. Locke’s definition of a person would require them to possess a certain level of intellectual understanding and poses innate characteristic, such as those possessed by human, however this will evidently exclude all other animals from this category. The contextual meaning of consciousness also helps derive of the concept of self.
In Appendix I., Concerning Moral Sentiment, David Hume looks to find a place in morality for reason, and sentiment. Through, five principles he ultimately concludes that reason has no place within the concept of morality, but rather is something that can only assist sentiment in matters concerning morality. And while reason can be true or false, those truths or falsities apply to facts, not to morality. He then argues morals are the direct result of sentiment, or the inner feeling within a human being. These sentiments are what intrinsically drive and thus create morality within a being. Sentiments such as beauty, revenge, pleasure, pain, create moral motivation, and action, and are immune to falsity and truth. They are the foundation for which morals are built, and exist themselves apart from any reasoning. Thesis: In moral motivation, the role of sentiment is to drive an intrinsically instilled presence within us to examine what we would deem a moral act or an immoral act, and act accordingly, and accurately upon the sentiments that apply. These sentiments may be assisted by reasons, but the reason alone does not drive us to do what we would feel necessary. They can only guide us towards the final result of moral motivation which (by now it’s painfully clear) is sentiment.
David Hume was a Scottish philosopher known for his ideas of skepticism and empiricism. Hume strived to better develop John Locke’s idea of empiricism by using a scientific study of our own human nature. We cannot lean on common sense to exemplify human conduct without offering any clarification to the subject. In other words, Hume says that since human beings do, as a matter of fact, live and function in this world, observation of how humans do so is imminent. The primary goal of philosophy is simply to explain and justify the reasoning of why we believe what we do.
So the mind at birth is a tabula rasa, a blank slate, and is informed only by “experience,” that is, by sense experience and acts of reflection. Locke built from this an epistemology beginning with a pair of distinctions: one between SIMPLE and COMPLEX ideas and another between PRIMARY and SECONDARY qualities. Simple ideas originate in any one sense (though some of them, like “motion,” can derive either from the sense of sight or the sense of touch). These ideas are simple in the sense that they cannot be further broken down into yet simpler entities. (If a person does not understand the idea of “yellow,” you can’t explain it to him. All you can do is point to a sample and say, yellow.) These simple ideas are Locke’s primary data, his psychological atoms. All knowledge is in one way or another built up out of them.
Empiricism (en- peiran; to try something for yourself): The doctrine that all knowledge must come through the senses; there are no innate ideas born within us that only require to be remembered (ie, Plato). All knowledge is reducible to sensation, that is, our concepts are only sense images. In short, there is no knowledge other than that obtained by sense observation.
