About this topic
Summary

Traditionally, knowledge has been taken to yield a reductive analysis in terms of (conceptually primitive) necessary and jointly sufficient conditions—most commonly, justified (or warranted) true belief. In 1963, however, Edmund Gettier’s “Is Knowledge Justified True Belief?” challenged the reductive model of knowledge by producing a series of counterexamples where, intuitively, a justified true belief fails to be knowledge. Since Gettier’s original challenge, the philosophical literature has been replete with attempts to defend the reductive analysis against Gettier counterexamples (now generalized well beyond the cases posed in 1963) and those claiming that such defenses fail. 

Key works Gettier 1963 is the piece that started it all, and should be the first point of contact with the literature. And Shope 1983 provides an excellent summary of the first 20 years following Gettier's landmark paper. While there is certainly a legion of accounts aiming to provide a viable reductive account of knowledge that is not vulnerable to Gettier counterexample, four seminal accounts can be found here: Hetherington 2001Howard-Snyder 2003, Zagzebski 1999, and Nozick 1981. Other philosophers have tried to defuse Gettier counterexamples by challenging the intuitions that inform and undergird them. See Weatherson 2003 and Weinberg et al 2001. Finally, it is worth noting that some philosophers have argued that Gettier counterexamples are unavoidable within the reductive model of knowledge. See Zagzebski 1994, Floridi 2004, and Church 2010

    Resolving the Gettier Problem in the Smith Case: The Donnellan Linguistic Approach.Joseph Martin M. Jose & Mabaquiao Jr - 2018 - Kritike 12 (2):108-125.
    In this paper, we contend that the “Smith case” in Gettier’s attempt to refute the justified true belief (JTB) account of knowledge does not work. This is because the said case fails to satisfy the truth condition, and thus is not a case of JTB at all. We demonstrate this claim using the framework of Donnellan’s distinction between the referential and attributive uses of definite descriptions. Accordingly, the truth value of Smith’s proposition “The man who will get the job has (...)

    I Know I Am Not Gettiered.Michael Veber - 2013 - Analytic Philosophy 54 (4):401-420.
    In a Normal Case, a subject has a justified true belief that P and also knows that P. In a Gettier Case, a subject has a justified true belief that P but does not know that P. The received view (endorsed by Lycan and others) is that if one is in a Normal Case then one cannot know that he is not in a Gettier case. I argue that the received view is mistaken and I discuss the implications this has (...)

    Groundwork for an Explanationist Account of Epistemic Coincidence.David Faraci - 2019 - Philosophers' Imprint 19 (4).
    Many philosophers hold out hope that some final condition on knowledge will allow us to overcome the limitations of the classic "justified true belief" analysis. The most popular intuitive glosses on this condition frame it as an absence of epistemic coincidence. In this paper, I lay the groundwork for an explanationist account of epistemic coincidence—one according to which, roughly, beliefs are non-coincidentally true if and only if they bear the right sort of explanatory relation to the truth. The paper contains (...)

    Modal Virtue Epistemology.Bob Beddor & Carlotta Pavese - forthcoming - Philosophy and Phenomenological Research.
    This essay defends a novel form of virtue epistemology: Modal Virtue Epistemology. It borrows from traditional virtue epistemology the idea that knowledge is a type of skillful performance. But it goes on to understand skillfulness in purely modal terms — that is, in terms of success across a range of counterfactual scenarios. We argue that this approach offers a promising way of synthesizing virtue epistemology with a modal account of knowledge, according to which knowledge is safe belief. In particular, we (...)

    The Theory of Justification.James Richard Ciccotelli - 1981 - Dissertation, Princeton University
    Analytic epistemologists, over the last two decades, have been troubled by two vexing and seemingly unrelated problems. First they have been trying to describe the "structure" of justification of our knowledge claims; this enterprise has been called the "foundationalism debate." Secondly though, they have also been trying to formulate precisely the necessary and sufficient conditions for "knowing;" this difficulty has come to be known as the "Gettier Problem." The first project deals with epistemic justification and the second, with the analysis (...)

    Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is compatible with (...)

    An Externalist Decision Theory for a Pragmatic Epistemology.Brian Kim - 2019 - In Pragmatic Encroachment in Epistemology. Routledge.
    In recent years, some epistemologists have argued that practical factors can make the difference between knowledge and mere true belief. While proponents of this pragmatic thesis have proposed necessary and sufficient conditions for knowledge, it is striking that they have failed to address Gettier cases. As a result, the proposed analyses of knowledge are either lacking explanatory power or susceptible to counterexamples. Gettier cases are also worth reflecting on because they raise foundational questions for the pragmatist. Underlying these challenges is (...)

    Robust Virtue Epistemology As Anti‐Luck Epistemology: A New Solution.J. Adam Carter - 2016 - Pacific Philosophical Quarterly 97 (1):140-155.
    Robust Virtue Epistemology maintains that knowledge is achieved just when an agent gets to the truth through, or because of, the manifestation of intellectual virtue or ability. A notorious objection to the view is that the satisfaction of the virtue condition will be insufficient to ensure the safety of the target belief; that is, RVE is no anti-luck epistemology. Some of the most promising recent attempts to get around this problem are considered and shown to ultimately fail. Finally, a new (...)

    Higher Order Ignorance Inside the Margins.Sam Carter - forthcoming - Philosophical Studies:1-18.
    According to the KK-principle, knowledge iterates freely. It has been argued, notably in Greco, that accounts of knowledge which involve essential appeal to normality are particularly conducive to defence of the KK-principle. The present article evaluates the prospects for employing normality in this role. First, it is argued that the defence of the KK-principle depends upon an implausible assumption about the logical principles governing iterated normality claims. Once this assumption is dropped, counter-instances to the principle can be expected to arise. (...)

In the process, I will make full use of Socratic Epistemology’s methodology and commitments.

In this essay I explain that robust virtue epistemology faces a dilemma, and the viability of the theory depends on an adequate understanding of the ‘through’ relation. Greco interprets this ‘through’ relation as one of causal explanation; the success is through the agent’s abilities iff the abilities play a sufficiently salient role in a causal explanation of why she possesses a true belief.

    A Critique to the Significance of Gettier Counter-Examples.Cao Jianbo - 2006 - Frontiers of Philosophy in China 1 (4):675-687.
    Usually, people think that Gettier counter-examples challenged the traditional tripartite definition of knowledge and fundamentally changed the characteristic of the contemporary epistemology. This paper argues that regard for Gettier counter-examples is exaggerated, because (i) the JTB definition is neither an important nor a comprehensive one that covers all knowledge. Moreover, the significance of Gettier counter-examples is limited. (ii) The source of Gettier counter-examples lies in one arbitrary judgment, two mix-ups, three false assumptions, and a misunderstanding about the JTB definition.

    Gettier Cases Without False Lemmas?Michael Levin - 2006 - Erkenntnis 64 (3):381-392.
    Examples cited by Feldman, Lehrer and others of true beliefs that are justified, but not by false lemmas, turn out under scrutiny to involve false lemmas after all. In each case there is an EG inference whose conclusion is unwarranted unless its base instance is false. A shift to non-deductive justification does not avert the difficulty. The relation of this result to non-inferential Gettier cases is suggested.
