Recommended: Justified true belief theory

Most philosophers would say that the knowledge is not justified true belief. This can be demonstrated by the Gettier cases, however, these cases do not evidently refute the traditional belief that knowledge is justified true belief; this definition of knowledge is commonly attributed to Plato and his dialogues . This theory, however, suffered a significant setback when the aforementioned Gettier cases were discovered. "the explication of knowledge as 'justified true belief', though it involves many pitfalls...is, I believe essentially sound." Wilfrid Sellars (1975:99) Gettier may not have been the first to produce these cases names after him , but we will continue to call them Gettier cases nonetheless. He gave two cases in which intuitively a person gathers a justified true belief, however they fail to know. This demonstrated how justified true belief is not always sufficient for knowledge. Gettier uses a specific technique in his cases . He starts with a belief that is adequately justified so that it fulfils the justification requirement for knowledge. He then continues by adding a...

    In this book, many fallacious quotations were used to support Skousen’s viewpoints. These quotations were blindly accepted due to the attached name without proper insight into the context of the quotation. It seemed as if Skousen frequently misinterpreted his sources purposely to authenticate his argument, often without proper justification or a well-reasoned argument. The audience was ultimately misled to believe flimsy assertions with unproven conclusions; Skousen achieved this by supporting axioms that will be widely accepted and by jumping to conclusions with which we have

    669 Words  | 2 Pages

    Knowledge, its source and truthfulness have been under question for a long time. People have always wondered what exactly constitutes facts and if there are any defining laws that can be attributed to all knowledge or information available in the world. Many philosophers speculated on how information can be interpreted according to its falsity or truthfulness, but have not come to definite conclusions. Edmund Gettier has provided one of the key pieces in understanding and trying to figure out what knowledge really is.

  • Plato And Charles Peirce: The Meaning Of Truth, Knowledge And Knowledge

    947 Words  | 2 Pages

    For many years humans have pursued the meaning of truth, knowledge and understanding. For many this pursuit of understanding the meaning of truth doesn’t end until one finds a “truth” that is nourishing to them. Even if this is the case one may choose to look for an alternate truth that may be more satisfactory to them. This pursuit of truth does not always have to follow the same path as there may be different ideas for everyone on how truth is actually obtained and which is a better way to obtain the truth is. Two philosophers of their time, Plato and Charles Peirce had their own methodologies and ideas on how truth and knowledge could be obtained.

  • The Tension Between Faith and Reason

    1647 Words  | 4 Pages

    Entering the ancient discussion about the tension between faith and reason is not an easy task. Of course, when engaging in tensions it is always important to define terms. For the sake of consistency I will refer to Oxford’s online dictionary for both the definition of faith, as well as reason. Faith is “complete trust or confidence in someone or something.” Reason is “a cause, explanation, or justification for an action or event.” These are the definitions that will be used throughout this paper. From the above definitions, the conclusion that is logically deduced is that reason precedes faith.

This paper will continue to give more examples of Pascals teachings of non-evidentialism and why I agree with them.

  • What Is Correlation And Causation

    1537 Words  | 4 Pages

    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

    1436 Words  | 3 Pages

    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.

  • Why Causal Connections Do Not Solve the Gettier Problem

    828 Words  | 2 Pages

    First, when looking at the causal chain theory it is imperative that we understand the basis of what it is trying to do which is to attempt to solve The Gettier problem. So, in order to continue in the building of my argument I will briefly cover what said problem was in an effort to show how the causal theory of knowledge fails to solve the problem that Gettier proposed. In brief: the Gettier problem pointed out that knowledge requires more than a true justified belief. An example that Gettier provides is one where a man: Smith, is told by a potential employer that the man that will be getting the job has ten coins in his pocket, Smith then is justified in believing that Johnson: another man who interviewed for the same position, will be the one getting the job as Smith knows without a doubt that Johnson has 10 coins in his pocket. However Smith ends up getting the job as he unknowingly also had ten coins in his pocket. Smith was justified in believing that the man that has ten coins in his pocket will be getting the job, however we cannot say that Smith truly had knowledge based on this account because he wrongly assumed that Johnson would be getting the job. Hence Gettier said that there must be more to knowledge than true justified beliefs.

  • The Justified True Belief Theory Of Knowledge

    1519 Words  | 4 Pages

    The Justified True Belief (JTB) theory of knowledge, often attributed to Plato , is a fairly straightforward theory of knowledge. It states that something must be true if person S believes proposition P, proposition P is true, and S is justified in believing in believing that P is true . While many consider the JTB theory to be vital to the understanding of knowledge, some, such as American Philosopher Edmund Gettier, believe that it is flawed. I tend to agree with Gettier and others who object to the JTB theory as an adequate theory of knowledge, as the JTB theory allows for a type of implied confirmation bias that can lead people to be justified in believing they know something even though it isn’t true.

  • 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.
