Socrates and the Theaetetus
THE ORIGIN OF THE ‘GETTIER’ PROBLEM: SOCRATES AND THE THEAETETUS Michael JENKINS ABSTRACT: This article discusses the origin of what has become known as the Gettier Problem. It examines the claim put forward, though not expounded or defended, by J. Angelo Corlett in Analyzing Social Knowledge that the basis for Edmund Gettier’s article “Is Justified True Belief Knowledge?” was originally argued for in Plato’s Theaetetus. In his article, Gettier argues that the Justified True Belief condition is not sufficient for knowledge. However, Corlett questions the originality of this argument. This article examines Gettier’s article followed by the Theatetus. After which, the two articles are compared, and the claim is shown to be correct in accusing Gettier of failing consider the full work of the Theaetetus. Socrates also argued that the Justified True Belief condition was not sufficient for knowledge. However, this article concludes by arguing that Socrates went further with his examination than Gettier did. Socrates not only put forward the claim that this condition was insufficient for knowledge, he also tried to supply answers to the problem. KEYWORDS: Gettier, Theaetetus, epistemology, Socrates, coherentism, justification 1. Introduction In Analyzing Social Knowledge, J. Angelo Corlett states that Edmund L. Gettier, in his infamous article “Is Justified True Belief Knowledge?”1 seems to merely reiterate what Socrates (in Plato’s Theaetetus) already articulates: that “simple justified true belief is insufficient for knowledge.”2 In this article, I will argue that Corlett’s statement is correct. I will argue that it originated not with Gettier, but at least as far back into the writing of western philosophy as Socrates. -
Some Reflections on Gettier's Problem
Some Reflections on Gettier’s Problem Golam Azam * It is one of the basic problems of epistemology to define knowledge. Epistemology is one of the branches of philosophy that discusses about the definition, sources, validity and limitations of knowledge. From Socrates to till date this problem is being discussed by most of the eminent philosophers; ancient, medieval, modern or contemporary- eastern or western- Indian, Muslim, Chinese or Buddhist philosophers. Why knowledge is important, what the criterion of truth is, are also the basic issues of discussion of the philosophers of the ages. E. Gettier, an American epistemologist, published a paper of only three pages entitled “Is Justified True Belief Knowledge?” in 1963 where he challenged the age-old definition of knowledge. Traditionally knowledge is defined as ‘justified true belief’. Gettier showed that these three conditions are not enough for the definition of knowledge. In this paper, Gettier’s conception regarding the definition of knowledge will be analyzed and in this connection the reaction of the contemporary epistemologists will also be interpreted and analyzed. It will be showed that now a day the fundamental problem of knowledge is not to define ‘knowledge’ rather the problem is mainly regarding the justification of the statement of knowledge. I Before the publication of Gettier's paper knowledge was widely defined as justified true belief. It is the pre-Gettier definition of knowledge. After the publication of Gettier’s paper the term ‘Gettier problem’ has become well known to the contemporary philosophers. Gettier problems or cases are named in honor of the American philosopher Edmund Gettier. -

Infallibilism and Easy Counter-Examples
grazer philosophische studien 95 (2018) 475-499 brill.com/gps Infallibilism and Easy Counter-Examples Alex Davies University of Tartu [email protected] Abstract Infallibilism is commonly rejected because it is apparently subject to easy counter- examples. The author describes a strategy that infallibilists can use to resist this ob- jection. Because the sentences used in the counter-examples to express evidence and belief are context-sensitive, the infallibilist can insist that such counter-examples trade on a vacillation between different readings of these sentences. The author describes what difficulties await those who try to produce counter-examples against which the proposed strategy is ineffective. Keywords context-sensitivity – counter-examples – entailment – infallibilism 1 The Example Based Objection Infallibilism about evidence-based belief is the following thesis: Infallibilism A knows that P on the basis of evidence E only if E entails P.1 1 I restrict attention to evidence-based belief because I don’t want infallibilism to turn out false simply because there’s such a thing as knowledge that is not based on evidence. Defenders of infallibilism (more or less so understood) include Bonjour (2010), Dodd (2011), Ledding- ton (forthcoming), McDowell (1982), and Travis (2005). Unlike the others, Bonjour and Dodd both defend infallibilism and either argue (in the case of (Dodd, 2007)) or grant (in the case of (Bonjour, ibid)) that infallibilism implies scepticism. © koninklijke brill nv, leiden, 2018 | doi 10.1163/18756735-000054Downloaded from Brill.com09/27/2021 09:56:17AM via free access <UN> 476 Alex Davies Infallibilism is the kind of philosophical thesis that undergraduates have to be taught out of believing—in the first instance, untutored intuition tends to be in its favour. -
A Critical Survey of Some Recent Philosophical Research in China
Philosophia DOI 10.1007/s11406-016-9768-x A Critical Survey of Some Recent Philosophical Research in China Xingming Hu1 Received: 12 January 2016 /Revised: 23 March 2016 /Accepted: 16 September 2016 # Springer Science+Business Media Dordrecht 2016 Abstract In this paper, I survey some recent literature produced by the established Chinese philosophers who regularly publish in Chinese philosophy journals and work in Mainland China. Specifically, I review the recent research of these philosophers in two areas: Chinese Philosophy and epistemology. In each area, I focus on two topics that have caught the attention of a lot of Chinese philosophers. I argue that the Chinese philosophers’ research on these topics has two prevalent problems: (i) a lot of argu- ments they make are weak; (ii) they tend not to critically engage with others. I discuss a metaphilosophical objection that weak argumentation and disengagement are not vices of philosophical research. I also try to make sense of (i) and (ii) in terms of some cultural factors. Keywords The goal of philosophy. Chinese philosophy. The legitimacy problem . Confucian ethics . Epistemology . The Gettier Problem .

In this paper, I survey some recent literature produced by the established Chinese philosophers who regularly publish in Chinese philosophy journals and work in Mainland China.

In each area, I focus on two topics that have caught the attention of a lot of Chinese philosophers.

Truth Analysis of the Gettier Argument
TRUTH ANALYSIS OF THE GETTIER ARGUMENT YUSSIF YAKUBU Published in: METAPHILOSOPHY Vol. 47, No. 3, July 2016, 449-466 Abstract: Gettier (1963) presented the now famous Gettier problem as a challenge to epistemology. The methods Gettier used to construct his challenge, however, utilized certain principles of formal logic that are actually inappropriate for the natural language discourse of the Gettier cases. In that challenge to epistemology, Gettier also makes truth claims that would be considered controversial in analytic philosophy of language. The Gettier challenge has escaped scrutiny in these other relevant academic disciplines, however, because of its fac¸adeas an epistemological analysis. This article examines Gettiers methods with the analytical tools of logic and analytic philosophy of language. Keywords: definite description, Russellian quantification, Edmund Gettier, referents and truth, classical logic. Introduction Gettier cases are hypothetical scenarios that purport to demonstrate, contrary to the standard epistemological view, that justified true belief (JTB) is not a sufficient condition for knowledge. In a typical Gettier- type case, a premise that “justifiably” leads an agent to a belief turns out to be false, but the belief the agent derives turns out “by coinci- dence to be true.” The believing agent in question is thus deemed to have a true belief that is justifiably reached, and he therefore, while satisfying the conditions for knowledge, nevertheless does not have knowledge, because the premise upon which he formed his belief is false. Epistemologists have generally taken Gettiers arguments against JTB to be successful, and have been trying, for the five decades since Gettiers paper, to come up with a definition or conception of knowl- edge that would not be undermined by the Gettier-challenge (Zagzeb- ski 1994; Shope 2002, 33; Sosa 2007; see also Kvanvig 2011, 29). -

Epistemology
Epistemology Lecture 9: Naturalism Dr. Ioannis Votsis (NCH) [email protected] www.votsis.org Chapter I: Naturalism in Epistemology Where things stand • Last week we looked at the debate surrounding local and global versions of scepticism. • This week we consider an entirely new way of doing epistemology, viz. naturalism or as it is sometimes called ‘naturalised epistemology’. 3 An alternative to foundationalism • The expression ‘naturalised epistemology’ was coined by Quine (1969). • Quine offers this view as an alternative to traditional epistemology and in particular to its preoccupation with (empiricist) foundationalism. • What is empiricist foundationalism? Simple form: Statements are inferentially justified by basic empirical statements, the latter being non-inferentially justified by experience. Embellished form: Even the meaning of statements is determined by experience. This is the so-called ‘verificationist principle’: • Quine thinks that, as a project, empiricist foundationalism has failed because it hasn’t lived up to its promise to reduce everything thus. 4 Replacement naturalism • Quine urges the abandonment of epistemology and the adopting of psychology (and other relevant sciences) in its stead: “The stimulation of his sensory receptors is all the evidence anybody has had to go on, ultimately, in arriving at his picture of the world. Why not just see how this construction really proceeds? Why not settle for psychology?” (1969, p. 75). “Epistemology, or something like it, simply falls into place as a chapter of psychology and hence of natural science. It studies a natural phenomenon, viz., a physical human subject.” (p. 82) • This view has come to be known as ‘replacement naturalism’ or ‘eliminative naturalism’. -

Oxford: Clarendon Press, 2005. Pp. xii + 290. Duncan Pritchard’s Epistemic Luck is a wide-ranging, nicely written, and generally masterful treatment of the concept of epistemic luck and its relevance to contemporary epistemology. Its central focus is what Pritchard calls the “epistemic luck platitude,” which is the claim that knowledge excludes luck. This claim is widely (if largely uncritically) accepted among epistemologists; and yet an unqualified endorsement of it is problematic, for there are many putative instances of knowledge in which an agent’s reaching the truth is in some sense a matter of luck (e.g., the archeologist who “happens” upon an important find or the detective who stumbles across a critical clue). Pritchard’s aim is to clarify the sense in which knowledge excludes luck and to consider the resulting implications for the theory of knowledge. -

REP Knowledge
Knowledge, Concept of Routledge Encyclopedia of Philosophy Michael Hannon University of Nottingham Keywords: knowledge; ignorance; justification; scepticism Article Summary The word ‘know’ is exceptional for a number of reasons. It is one of the 10 most commonly used verbs in English, alongside basic verbs like ‘be,’ ‘do,’ ‘say,’ ‘have,’ and ‘go.’ It is also the most frequently used term in epistemic evaluation: we speak of ‘knowing’ far more often than we speak of ‘justification,’ ‘reliability,’ ‘understanding,’ ‘wisdom,’ and other intellectual traits or epistemic properties. Perhaps most strikingly, the word ‘know’ allegedly has a meaning-equivalent in every human language. Unlike almost every other word in English, linguists have identified ‘know’ as one of a very small number of words that are culturally universal (Goddard 2010). These facts suggest that knowledge is deeply important to human life. Knowledge has also held a central place in epistemology. Indeed, the word ‘epistemology’ comes from the Greek word epistêmê, which is often translated as ‘knowledge.’ This is not to say that epistemologists are only interested in knowledge. They also investigate epistemic virtues like open- mindedness and intellectual humility, as well as properties of belief like being rational and justified (among many other things). Still, the enterprise of epistemology has largely been an investigation into the nature, significance, sources, and extent of human knowledge. But what is knowledge? Why do we value it? How is it acquired? And how much of it do we have? In the late 20th century, one of the central questions asked by epistemologists was: When does a true belief count as knowledge? It was widely assumed that knowledge is a form of true belief plus some additional requirement(s), such as justification or reliability.
