Knowledge: Austin, Descartes, and Stroud This paper will be covering what knowledge essentially is, the opinions and theories of J.L. Austin, Descartes, and Stroud, and how each compare to one another. Figuring out what knowledge is and how to assess it has been a discussion philosophers have been scratching their heads about for as long as philosophy has been around. These three philosophers try and describe and persuade others to look at knowledge in a different light; that light might be how a statement claiming knowledge is phrased, whether we know anything at all for we may be dreaming, or maybe you’re just a brain in a vat and don’t know anything about what you perceive the external world to be. Before one can start talking about specific …show more content…
There is no concrete definition of knowledge, but there is a definition that is widely agreed upon, or a standard definition. This definition may be widely accepted, but just like most things in philosophy, it is controversial and many disagree with it. The definition involves three conditions that must be met in order for one to truly say that they know something to be true. If one were to state: “The Seattle Mariners have never won a world series,” using the standard definition would look like this: first, the person believes the statement to be true. Second, the statement is in fact true. Third, the person is justified in believing the statement to be true. The three conditions are belief, truth, and justification. There are the “necessary and sufficient conditions” for knowledge. Necessary and sufficient conditions are linked to conditional statements, ‘if x, then y’ statements. …show more content…
The first, Stroud brings up Austin’s claim that, to raise a legitimate doubt about someone’s knowledge claim, one must suggest some specific way in which the subject might be mistaken. “If you say ‘That’s not enough’, then you must have in mind some more or less definite lack…if there is no definite lack, which you are at least prepared to specify on being pressed, then it’s silly just to go on saying ‘That’s not enough’.” Next, Stroud discuses Austin’s claim that dreams are qualitatively distinguishable from no dreaming experiences. Austin believes dreams always have a special “dream-like quality” that one can use to help distinguish the difference between waking and dreaming experiences. Austin says that “there are recognized ways of distinguishing between dreaming and waking, ‘how otherwise should we know how to use and to contrast the words, or to know between something being stuffed or live, and so forth.” The last aspect Stroud touches upon when discussing Austin, is that you only need to rule out some possibility if there’s some special reason to believe that it does now obtain. Meaning, only in special instances does one have to worry about asking if you are in a dream state. Typically, in the real world, the question if one is dreaming or not when checking validity is not taken seriously, nor should it be taken as a serious procedure to see if something is fact or not. For example, suppose I
How we approach the question of knowledge is pivotal. If the definition of knowledge is a necessary truth, then we should aim for a real definition for theoretical and practical knowledge. Methodology examines the purpose for the definition and how we arrived to it. The reader is now aware of the various ways to dissect what knowledge is. This entails the possibility of knowledge being a set of truths; from which it follows that one cannot possibly give a single definition. The definition given must therefore satisfy certain desiderata , while being strong enough to demonstrate clarity without losing the reader. If we base our definition on every counter-example that disproves our original definition then it becomes ad hoc. This is the case for our current defini...
Williamson in his book Knowledge and It’s Limits primarily seeks to support his novel perspective of “knowledge first” epistemology (v). This approach sets forth the idea that knowledge cannot be analyzed into more basic concepts, such as belief or truth. The basis for this argument is that knowledge is a mental state, and thus it cannot be broken down into the combination of external conditions – like the state of the world such that it makes a proposition true – and internal conditions – like belief in a proposition or the justification of that belief (6). Certainly, Williamson is able to illustrate in his introduction the way in which he equates belief and knowledge as mental states, and refutes the idea that belief is conceptually prior to knowledge. However, Williamson takes the assertion that knowledge is a general factive mental state and supports this claim by offering it as a new approach to epistemology that avoids the problems of trying to analyze knowledge, and instead allows for knowledge to be the central concept used to elucidate others, like justification and eviden...
Knowledge according to Merriam- Webster’s dictionary is “acts, information, and skills acquired by a person through experience or education.” Rene Descartes saw knowledge being attained through deductive logic and would disagree with this definition. Charles Peirce’s pragmatic approach on the other hand is the reason we have that definition.
In the traditional analysis of knowledge, knowledge is defined as a justified true belief. The presence of these three requirements (i.e., justification,
Knowledge, that certain indescribable thing that everyone thinks they have a little bit of, is an elusive concept that nearly every philosopher from ancient Greece to the modern day has given at least a nod to. How, after all, can we know that we are right in something if we don't know what knowing is? This question, and the sometimes futile attempt to answer it, is called epistemology. More specifically, it is the study of how we know and what that knowledge actually is. Is knowledge objective, subjective, something else, or even possible?
The true-justified-belief theory of knowledge is an attempt to subject knowledge to analysis. The theory falls under the category of Epistemology, a branch of philosophy dealing with knowledge. The theory, in short, seeks to answer the question, what does it mean to know something? What parts lead up to a point, when someone can claim to have knowledge of something? The true-justified-belief theory of knowledge or “JTB” has three such components seeking to answer the aforementioned questions. The three components make up the theory’s analysis of knowledge. The analysis claims to demonstrate that in order to have sufficiency for knowledge, there must be a necessary justified, true belief.
The dictionary definition of knowledge is information acquired by a person through experience or education. Knowledge in the 21st century is viewed as a thought that is backed up by facts or evidence, therefore making this idea a very credible one to many. I believe that there is no such thing as knowledge, but rather justified true belief. The facts and the evidence used to amount to so called knowledge are just opinions of very educated people meaning they are falsifiable just like any other opinion. Edmund Gettier backs up this claim with, “it is possible for a person to be justified in a proposition that is in fact false” (109). On the other hand, a justified true belief is one that has plenty of evidence and reasons to believe that it is true, but it is also known that there could very well be evidence against this belief. A good example of justified true belief would be the principle of God. There is no way to know for a fact that the God people learn about and worship exists, for the fact that no one that is alive today has met God. However, as far as the other end of the argument goes there are reasons such as; reproduction, respiratory relationship between plants and humans, the urge to seek love, and many others to believe that God is alive and well today. If these ideas were facts that could be wholeheartedly
Since the beginning of the human race, people have sought out knowledge for survival, power, and curiosity. There is no real answer as to where knowledge comes from. Throughout history, great philosophers such as Plato, Augustine, and René Descartes have debated the source of knowledge and how we get it. This paper will demonstrate that, although Plato, Augustine, and Descartes all come up with explanations for how knowledge is obtained, Plato and Descartes have more sound arguments than those of Augustine.
How do we know what we know? Ideas reside in the minds of intelligent beings, but a clear perception of where these ideas come from is often the point of debate. It is with this in mind that René Descartes set forth on the daunting task to determine where clear and distinct ideas come from. A particular passage written in Meditations on First Philosophy known as the wax passage shall be examined. Descartes' thought process shall be followed, and the central point of his argument discussed.
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...
In Plato’s Theaetetus, Socrates examines the first definition of knowledge that theaetetus gives that knowledge is perception. Socrates gives us many example that both supports and refutes that knowledge is perception. The basic claim from Protagoras is that truth is based on the perception of every man. This means that things are to any person as they seem to that person. Socrates explains to us Protagoras’s view with the cold wind example. He say that through Protagoras theory, the wind is cold to the person that feels cold, and the wind is warm to the person that feels warm. Both “the wind is cold” and “the wind is war” is true according to Protagoras and it is based on the perception of the person. Then we learn from Socrates that if knowledge and truth is based on perception then everything that has perception has his own set of knowledge and truth. Also sense Protagoras not considering himself to be a god, and is on the same level of us then wouldn’t the truth and knowledge he definite in his doctrine only be his own set truth and knowledge for he only knows his own perspective.
Donald Davidson identifies three forms of knowledge which he believes to be irreducible and interdependent: knowledge of self, which is immediately known; knowledge of the outside world, which is simply caused by the events and objects around you, and thus depends on sense organs to be semi-immediately known, yet open to uncertainty; and knowledge of the minds of others, which is never immediately known. The standard approach to philosophy tries to reduce one of these forms of knowledge to one or two of the others, often leading to unanswerable questions. Davidson argues that all three varieties of knowledge are interdependent—that is, you cannot have any one without the other two. In this paper, I will primarily review Davidson’s argument of the interdependence of the three varieties of knowledge. I will then briefly discuss the plausibility of Davidson’s account and question if it truly can explain how we come to understand others’ feelings and emotions.
He began with: nothing shall be concluded as true unless it was fully proven so (p.8, Descartes). The second rule stated that all problems should be divided up into the smallest possible parts in order to make the analysis simpler. The third rule required Descartes to start simple and gradually increase the difficulty of the topics of his studies as he progressed. Finally, he required himself to regularly reassess his progress to make sure he did not skip over anything important (p.9, Descartes).
What is the source of knowledge? What can we know? Questions like these dominated western philosophy during the 17th and 18th century. This philosophical period was known as the epistemological turn. The quest for the source of knowledge was not an easy one. This question had led to many disagreements about the nature of knowledge, and a philosophical war was waged which would last two centuries. It began with the 17th century with a french philosopher by the name of Rene Descartes. The answer to his epistemological quest was rationalism. For Descartes rationalism was the key to keeping our reality in check. Descartes had undergone a process of purging all that he thought he knew to find the sole source of knowledge . After much examination Descartes came to the realization that there were few things that could be considered pure knowledge. Since most of the things we know come from the senses, and the senses were falliable. He made a crucial discovery that would forever change the face of philosophy. The mind he regarded is the tool and the that could lead to a pure source of knowledge unbridled by the senses. He believed that we can only trust our minds that which we can intuit or “deduce” on our own. Descartes called these ideas of knowledge a priori. A priori are ideas that are innate, and that we can only arrive at through a special kind of reasoning known as deductive reasoning.Descartes famously declares the statement “cogito ergo sum “to answer the question of our existence. Because if the senses are decieving who is to say that this world we live in is a lie created by a wicked genius we call god.”Descartes believed that if he existed it was because his mind was engaged in the process of thinking. In other words only ...
Plato and Aristotle propose theories of knowledge in which they both agree that the knower is measure by the known and that knowledge is an exchange within the world. However, their respective theories may be considered polar opposites of one another especially when considering that Aristotle rejects Plato’s theory and admits that ‘informed opinion’, is a form of knowledge whereas Plato rejects opinion as a form of knowledge.
