Ultimate Source of Knowledge Epistemology is the philosophical study of the nature of truth and knowledge. This branch of philosophical inquiry attempts to discover what truth and knowledge are, the process of how we obtain truth and knowledge, and the distinguishing differences between truth and falsity and knowledge and belief. The two opposing schools of thought of epistemology are rationalism and empiricism. Rationalism is the epistemological theory which claims that truth and knowledge stems from reasoning alone. The notion that some truths and knowledge are independent of our experiences supports this theory. “For example,” John Chaffee explains, “the principles of mathematics and logic have for the most part been developed independently …show more content…
This theory contradicts the notion of innate knowledge by claiming that we must make observations of the natural world and interpret this data in order to form truthful and knowledgeable concepts. A main supporting philosopher of empiricism was Aristotle who blatantly disagreed with his teacher, Plato. Although Aristotle was a metaphysical dualist, he believed that things existing of the physical world were more real than that of the immaterial world simply because ideas do not exist independently of human beings and our experiences. This claim of Aristotle 's thus supported his theory of empiricism. Another empiricist was John Locke who supposed that the mind is a “tabula rosa”, or blank slate, on which perceptions derived from our experiences are marked. This denied innate knowledge and to an extent denied knowledge through reasoning. Contrary to Spinoza 's infinitely rational God, George Berkeley supposed the infinite Being to be the ultimate perceive of all things. Berkeley follows, “And it seems no less evident that the various sensations or ideas imprinted on the sense, …, cannot exist otherwise than in a mind perceiving them” (Berkeley 152). All things are perceivable to humans because God is constantly perceiving them. This emphasizes knowledge through experience, rather than
Epistemology tells us how we come to acquire knowledge and what type of limits there are on our knowledge. Berkeley’s epistemological argument is that the physical and mental world are one-in-the-same. He denies the existence of an external world and believes that the world is only a collection of ideas in our heads. We only know things to be real as we experience them and we only experience our ideas. This leads Berkeley to the conclusion that for something to be real, that means that it is the object of some type of experience. Without epistemology, people would have no reason to believe in their thoughts and actions because there would be no difference between truth and error. We need epistemology to accept reality.
Believing that reason is the main source of knowledge is another clear distinction of rationalism. Rationalists believe that the 5 senses only give you opinions, not reasons. For example, in Descartes’ wax argument, he explains how a candle has one shape to begin with- but once the candle is lit, it begins to melt, lose its fragrance, and take on a completely different shape than it had started with. This argument proves that our senses can be deceiving and that they should not be trusted.
The epistemological concept questions “how do I know?” The epistemological dimension is how we view the assumptions of knowledge to decide what to believe (Marcia, 2008, p2). The way in which information is delivered affects how it perceived by those who receive the information. Intrapersonal dimension is how we chose and adopt the values and beliefs that we decide to live by (Marcia, 2008, p8). For example, as a student in the first phase of self-authorship, I seek my values and beliefs according to seeking acceptance from those around me, while others who may be further down the process chose their values and beliefs according to who they are. Interpersonal dimensions is the connection between yourself and with others (Marcia, 2008, p9). It is the understanding of others views and developing a mature and respectful way to interact with everyone. “Complex epistemological, intrapersonal, and interpersonal development is necessary for adults to build complex belief systems, to form a coherent sense of identity, and to develop authentic, mature relations with diverse others (Baxter Magolda, 2001).” Within this course, I believe that we have learned a bit of all of three dimensions.

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...
Descartes is a prime example of a rationalist. Descartes begins his Meditations on First Philosophy by doubting his senses in the first meditation. “From time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(Descartes: 12). In the second meditation, Descartes begins to rebuild the world he broke down in the first meditation by establishing cogito ergo sum with the aid of natural light. It is with this intuition that the cogito is established, from the cogito, intellect, from the intellect, knowledge; thus knowledge has been defined in this world that Descartes is constructing from scratch. Descartes uses the fact that he is a thinking thing to establish the existence of other things in the world with the cosmological and ontological arguments, as well as a meditation on truth and falsity. “So now I seem to be able to lay it down as a general rule that whatever I perceive very clearly and distinctly is true” (Descartes: 24). Descartes only utilizes his perceptions to establish ideas of the things t...
Empiricists and rationalists have proposed opposing theories of the acquisition of knowledge, which appear unable to coexist. Each theory holds its own strengths but does not demonstrate a strong argument in itself to the questions, “Is knowledge truly possible?” and “How is true knowledge obtained?”. Immanual Kant successfully merged the two philosophies and provided a convincing argument with his theory of empirical relativism, or what some may call constructivism. His theory bridges the gap between rationalism and empiricism and proves that empiricists and rationalists each present a piece of the full puzzle. In order to truly understand Kant’s epistemology, one must first review and understand both empiricism and rationalism on an impartial basis.
Rationalism and empiricism have always been on opposite sides of the philosophic spectrum, Rene Descartes and David Hume are the best representative of each school of thought. Descartes’ rationalism posits that deduction, reason and thus innate ideas are the only way to get to true knowledge. Empiricism on the other hand, posits that by induction, and sense perception, we may find that there are in fact no innate ideas, but that truths must be carefully observed to be true.
Epistemology helped me investigate the procedure I went through for crafting the essays. I referred to books, online articles, journal and other publications to understand and justify the concepts and information. It helped me distinguish between what is false, what is true across diverse contexts, and to decide the boundaries of knowledge based on how that knowledge is acquired. I also evaluated the truthfulness of my beliefs and personal opinion. I am actuated by understanding the sources of knowledge and also the quality of the resulting knowledge – knowing its dimensions and limitations.
Rationality from the Latin ‘rationari’ meaning to ‘think’ or ‘calculate’ is a significant concept in Western philosophy born out of the Enlightenment. During the 17th and 18th centuries many philosophers began to emphasise the use of reason as the best method of learning objective truth. Pioneers in this field include Descartes and Locke.
That everything in our mind is in idea. It all could be developed by human reason, not innate ideas. Locke goes on to describe his theory in order for your mind to gain knowledge humans will have to fill it up their brain with ideas, and learn through their five senses. Since, the innate ideas was not that relevant to Locke he needed to come up with another perceptions. Locke then suggested that external experience called as sensations; this experience which we can attain our knowledge through our senses that we have such as smells, touch and color. In other words, it is about analyses the characteristics of an object. The second kind of experience which Locke mentions is internal experience known as reflection, it is summarize those personal experience such as our thoughts, thinking, and feelings. He says that all knowledge come from sensations or reflection, “These two are the fountains of knowledge, from whence all the ideas we have, or can naturally have,” (page186). Therefore, the sense and observation make up the whole of knowledge. On the contrary, as for Descartes views he believes we do have innate
Epistemology, also known as theory of knowledge is the part of philosophy that discusses the nature and scope of knowledge. Some questions that study the nature of knowledge could be, Have you ever thought about how we know things? What does it mean for someone to know something? How much can we possibly know? How do you know that 2 + 2 = 4, or that the square root of 144 is 12? Do we know something from reason or from di...
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.
Empiricists claim that knowledge does not directly originate from reason, but it originates from experience. Empiricists also believe in reason, but assert that reason is a way to augment knowledge that derives from experiences. Empiricists contend that reality is the essence which produces theory through experience. This makes empiricism a reductionist epistemology as well as it reduces the idea of truth to experiences (Resnick & Wolff, 1987). One can argue that our thoughts literally contribute to our experiences and similarly our experiences help us to constitute our thoughts. Both events are connected to each other and each event helps to shape the other. This implies neither empiricism nor rationalism can be utilized as a fair way to deliver the
Epistemology is the branch of philosophy concerned with the theory of knowledge. Epistemology studies the nature of knowledge, justification, and the rationality of belief. Much of the debate in epistemology centers on four areas: the philosophical analysis of the nature of knowledge and how it relates to such concepts as truth, belief, and justification, various problems of skepticism, the sources and scope of knowledge and justified belief, and the criteria for knowledge and justification. Epistemology addresses such questions as "What makes justified beliefs justified?", "What does it mean to say that we know something?" and fundamentally "How do we know that we know?"
To provide solutions to philosophical problems such as, how world process was created, man must be in possession of rational, intuition, and intuitive knowledge. Rational knowledge is human reasoning and requires verification. The ability of man to reason while giving logical step by step demonstration and arguments is referred to as human knowledge and it has a rational source. According to Carriero and Broughton (2011), genuine rational knowledge is provided by clear and separate knowledge of wholesome intellect with sense deliverances interaction. Sen (1996) considers rational knowledge as the knowledge of change in states of specific entities, in the sense that human experience is a confirmation of change. What are its classes, provisions and philosophical problem associated with rational knowledge? The paper seeks to examine rational knowledge by addressing the above three issues.
