The Gettier problem, in the field of epistemology, is a landmark philosophical problem concerning the understanding of descriptive knowledge.Attributed to American philosopher Edmund Gettier, Gettier-type counterexamples (called "Gettier-cases") challenge the long-held justified true belief (JTB) account of knowledge. The JTB account holds that knowledge is equivalent to justified …

Feb 6, 2001 · Cases like these, in which justified true belief seems in some important sense disconnected from the fact, were made famous in Edmund Gettier’s 1963 paper, “Is Justified True Belief Knowledge?”. Gettier presented two cases in which a true belief is inferred from a justified false belief. He observed that, intuitively, such beliefs cannot ...

true, even though (i) (h) is true, (ii) Smith does believe that (h) is true, and (iii) Smith is justified in believing that (h) is true. These two examples show that definition (a) does not state a szflcient condition for someone's knowing a given proposition. The same cases, with appropriate changes, will suffice to show that neither definition

Oct 20, 2020 · Justified True Belief. In his dialogue Theaetetus, Plato presented what is known as the standard definition of propositional knowledge, which is justified true belief (abbreviated as JTB). On this definition, if a person knows something, then what he knows must be true. It does not make sense for John to say that he knows the dog is on the yard ...

The knowledge — the justified true belief — would be present in a correspondingly lucky way. One interpretive possibility — from Hetherington (2001) — is that of describing this knowledge that p as being of a comparatively poor quality as knowledge that p. Normally, knowledge that p is of a higher quality than this — being less ...

Feb 19, 2021 · What is knowledge? I this paper I defend the claim that knowledge is justified true belief by arguing that, contrary to common belief, Gettier cases do not refute it. My defence will be of the anti-luck kind: I will argue that (1) Gettier cases necessarily involve veritic luck, and (2) that a plausible version of reliabilism excludes veritic luck. There is thus a prominent and plausible ...

That is, just by luck, (2) is true. Now, we agreed that I don't in fact know (2). But the thing is, I have a justified true belief that (2). So here is a case in which I have justified true belief without knowledge. Since JTB says that anytime someone has a justified true belief that p, he thereby knows that p, JTB is proven to be false.

Fixing Plato’s Traditional Account of Knowledge. Gettier cases demonstrate that Plato ’s traditional account of knowledge as justified true belief is wrong. Specifically, Gettier cases show that a belief being true and justified is not sufficient for that belief to count as knowledge. In all the cases discussed, the subject seems to have a justified true belief but not knowledge.

May 31, 2017 · The justified true belief account of knowledge is that knowing something is no more than having a justified belief that it is true, and indeed its being true. There is a common impression that the justified true belief (JTB) definition of knowledge is due to Plato and was undermined by Gettier in his paper.Gettier himself says, “Plato seems to be considering some …

3.3 The Gettier challenge. Gettier [1963] pointed out examples that effectively jettisoned the justified true belief analysis of knowledge. The ensuing discussions are central to modern epistemology. For an overview of the area, see, e.g., Steup [Spring 2006].. Perhaps the easiest related example in epistemic logic is the following.
