Interest in social epistemology and work in this area have exploded in recent years with the publication of a vast quantity of exciting and wholly new research on a broad range of topics. This handbook provides new work on some of the most cutting-edge and important issues in this fertile and rapidly growing area of philosophy. While some of the ch...

In ‘Trustworthy Artificial Intelligence’, we develop a novel account of how it is that AI can be trustworthy and what it takes for an AI to be trustworthy. In this paper, we respond to a suite of recent comments on this account, due to J. Adam Carter, Dong-yong Choi, Rune Nyrup, and Fei Song. We would like to thank all four for their thoughtful eng...

Abstact This paper considers two recent views on the structure of justification and closure of knowledge by Ernest Sosa. It provides reason to believe that neither view is ultimately viable and sketches a better alternative.

The phenomenon of defeat is hot in epistemology. However, surprisingly little attention has been paid to defeat in the semantics of aesthetic discourse and aesthetic epistemology. We think that this is a lack that needs supplying. Here, we argue for a conditional claim: if epistemic defeat about aesthetic matters—what we will call, for convenience,...

Defeat is the loss of justification for believing something in light of new information. This Element mainly aims to work towards developing a novel account of defeat. It distinguishes among three broad views in the epistemology of defeat: scepticism, internalism, and externalism and argues that that sceptical and internalist accounts of defeat are...

Capacitism is the view that capacities come first in epistemological theorising: they are explanatorily basic and key epistemic phenomena are to be analysed in terms of capacities. This paper develops a problem for capacitism and outlines a motivated way of solving it.

This paper develops an account of trustworthy AI. Its central idea is that whether AIs are trustworthy is a matter of whether they live up to their function-based obligations. We argue that this account serves to advance the literature in a couple of important ways. First, it serves to provide a rationale for why a range of properties that are wide...

This paper develops a novel, bifocal account of trustworthiness according to which both trustworthiness simpliciter (as in ‘Ann is trustworthy’) and trustworthiness to phi (as in ‘Ann is trustworthy when it comes to keeping your secrets’) are analysed in terms of dispositions to fulfil one's obligations. We also offer a systematic account of the re...

Virtue epistemology is the view that beliefs are attempts at truth (or perhaps knowledge) and, as a result, can be assessed as successful, competent, and apt. Moreover, virtue epistemology identifies central epistemic properties with normative properties of beliefs as attempts. In particular, knowledge is apt belief and justified belief is competen...

Assertion is the central vehicle for the sharing of knowledge. Whether knowledge is shared successfully often depends on the quality of assertions: good assertions lead to successful knowledge sharing, while bad ones don't. In Sharing Knowledge, Christoph Kelp and Mona Simion investigate the relation between knowledge sharing and assertion, and dev...

Chapter 2 discusses a number of classical problems for the knowledge rule of assertion and argues that these problems can be solved. Worth special notice here is a general normative framework with accounts of criticisability, blamelessness and blameworthiness that we develop. Applied to the case of assertion, this framework allows us to give a well...

Chapter 4 introduces the first part of the functionalist account of assertion. We introduce the account of e-functions and their normative import. We then argue for our thesis concerning the e-function of assertion and derive our preferred account of good assertion. We show that our account compares favourably with its standard rule first rival.

This paper connects two important debates in epistemology—to wit, on the goal of inquiry and on the nature of understanding—and offers a unified knowledge-based account of both.

This paper critically assesses Sosa’s normative framework for performances as well as its application to epistemology. We first develop a problem for one of Sosa’s central theses in the general theory of performance normativity according to which performances attain fully desirable status if and only if they are fully apt. More specifically, we arg...

One popular view in recent years takes the source of testimonial entitlement to reside in the intrinsically social character of testimonial exchanges. This paper looks at two extant incarnations of this view, what we dub ‘weak’ and ‘modest’ social anti-reductionism, and questions the rationales behind their central claims. Furthermore, we put forth...

According to what Williamson labels ‘the C account of assertion’, there is one and only one rule that is constitutive of assertion. This rule, the so-called ‘C Rule’, states that one must assert p only if p has property C. This paper argues that the C account of assertion is incompatible with any live proposal for C in the literature.

Can we engineer conceptual change? While a positive answer to this question would be exciting news for philosophy, there has been a growing number of pessimistic voices in the literature. This paper resists this trend. Its central aim is to argue not only that conceptual engineering is possible but also that it is not even distinctively hard. In or...

This book combines virtue reliabilism with knowledge first epistemology to develop novel accounts of knowledge and justified belief. It is virtue reliabilist in that knowledge and justified belief are accounted for in terms of epistemic ability. It is knowledge first epistemological in that, unlike traditional virtue reliabilism, it does not unpack...

This paper offers a novel account of the value of knowledge. The account is novel insofar as it advocates a shift in focus from the value of individual items of knowledge to the value of the commodity of knowledge. It is argued that the commodity of knowledge is valuable in at least two ways: (i) in a wide range of areas, knowledge is our way of be...

The lottery paradox shows that the following three individually highly plausible theses are jointly incompatible: (i) highly probable propositions are justifiably believable, (ii) justified believability is closed under conjunction introduction, (iii) known contradictions are not justifiably believable. This paper argues that a satisfactory solutio...

In this paper, we develop a general normative framework for criticisability, blamelessness and blameworthiness in action. We then turn to the debate on norms of assertion. We show that an application of this framework enables champions of the socalled knowledge rule of assertion to offer a theoretically motivated response to a number of putative co...

When in the business of offering an account of the epistemic normativity of belief, one is faced with the following dilemma: strongly externalist norms fail to account for the intuition of justification in radical deception scenarios, while milder norms are incapable to explain what is epistemically wrong with false beliefs. This paper has two main...

Recent knowledge first epistemology features a number of different accounts of justified belief, including a knowledge first reductionism according to which to believe justifiably is to know Sutton (2005, 2007), Littlejohn (Forthcoming a, b), Williamson (2000, 2010), a knowledge first version of accessibilism Millar (2010) and a knowledge first ver...

The literature on the nature of understanding can be divided into two broad camps. Explanationists believe that it is knowledge of explanations that is key to understanding. In contrast, their manipulationist rivals maintain that understanding essentially involves an ability to manipulate certain representations. The aim of this paper is to provide...

In Kelp (2009a), it is argued that there are epistemic Frankfurt cases that serve to show that knowledge does not require safety from error. In this paper, these Frankfurt cases are revisited. It is first argued that a recent response to the earlier argument by Duncan Pritchard remains unsatisfactory. Then it is shown that Frankfurt cases impact a...

Virtue epistemological accounts of knowledge claim that knowledge is a species of a broader normative category, to wit of success from ability. Fake Barn cases pose a difficult problem for such accounts. In structurally analogous but non-epistemic cases, the agents attain the relevant success from ability. If knowledge is just another form of succe...

A common presupposition in epistemology is that the processes contributing to the generation of knowledge do not extend beyond the knower's skin. This paper challenges this presupposition. I adduce a novel kind case that causes trouble for a number of even the most promising accounts of knowledge in current literature (virtue epistemological and mo...

Traditionally, epistemologists have held that only truth-related factors matter in the question of whether a subject can be said to know a proposition. Various philosophers have recently departed from this doctrine by claiming that the answer to this question also depends on practical concerns. They take this move to be warranted by the fact that p...

In a recent exchange, Vaesen (Synthese 181: 515–529, 2011; Erkenntnis 78:963–970, 2013) and Kelp (Erkenntnis 78:245–252, 2013a) have argued over whether cases of extended cognition pose (part of) a problem for robust virtue epistemology. This paper responds to Vaesen’s (Erkenntnis 78:963–970, 2013) most recent contribution to this exchange. I argue...

Igor Douven has recently developed a challenge for accounts of justification according to which beliefs about lottery losers are never justified. This article argues that champions of such accounts can rise to Douven's challenge and, what's more, that they can turn Douven's argument around in the sense that they can legitimately take it to provide...

In a number of recent pieces, Duncan Pritchard has used cases with the structure of Goldman’s infamous fake barn case to argue against (i) a promising virtue epistemological account of knowledge and (ii) a promising knowledge-based account of understanding. This paper aims to defend both of these views against Pritchard’s objections. More specifica...

This paper takes issues with a couple of recent arguments due to Ernest Sosa according to which (i) knowledge is the norm of assertion and (ii) the thesis that knowledge is specially valuable is equivalent to the thesis that knowledge is the norm of assertion. It is argued that while both of these arguments fail, an argument that knowledge is the n...

According to a much discussed argument, reliabilism is defective for making knowledge too easy to come by. In a recent paper, Weisberg aims to show that this argument relies on a type of reasoning that is rejectable on independent grounds. We argue that the blanket rejection that Weisberg recommends of this type of reasoning is both unwarranted and...

Duncan Pritchard has recently defended an account of knowledge that combines a safety condition with an ability condition on knowledge. In order to explain this bipartite structure of knowledge he appeals to Edward Craig's work on the concept of knowledge. is paper argues that Pritchard's envisaged explanation fails and offers a better alternative.

Much recent discussion in social epistemology has focussed on the question of whether peers can rationally sustain a disagreement. A growing number of social epistemologists hold that the answer is negative. We point to considerations from the history of science that favor rather the opposite answer. However, we also explain how the other position...

AbstractA majority of philosophers nowadays hold that the practice of assertion is governed by the rule that one must assert only what one knows. In his last published paper, Paolo Casalegno sides with this view and criticizes rival accounts of assertion on which rational belief or rational credibility will do for warranted assertion. We take issue...

According to virtue epistemology, knowledge involves cognitive success that is due to cognitive competence. This paper explores the prospects of a virtue theory of knowledge that, so far, has no takers in the literature. It combines features from a couple of different virtue theories: like Pritchard's [forthcoming; et al. 2010] view, it qualifies a...

This paper addresses the argument from ' contextualist cases'—such as for instance DeRose's Bank cases—to attributor contextualism. It is argued that these cases do not make a decisive case against invariantism and that the debate between contextualists and invariantists will have to be settled on broader theoretical grounds.

In this paper I take issue with Jonathan Sutton's attempt at defending the thesis that knowledge is justified belief. I argue, first, that the arguments he adduces in support of it fail. Second, I provide independent reason to believe that knowledge and justified belief come apart.

This paper raises a problem for contrastivist accounts of knowledge. It is argued that contrastivism fails to succeed in providing a modest solution to the sceptical paradox—i.e. one according to which we have knowledge of a wide range of ordinary empirical propositions whilst failing to know the various anti-sceptical hypotheses entailed by them—w...

This paper defends the knowledge rule of informative speech acts. It is argued that Edward Craig's insightful practical explication of the concept of knowledge can be extended to motivate the knowledge rule. A number of problem cases for the knowledge rule are addressed and accommodated.

This paper highlights some connections between work on truth approximation and work in social epistemology, in particular work on peer disagreement. In some of the literature on truth approximation, questions have been addressed concerning the efficiency of research strategies for approximating the truth. So far, social aspects of research strategi...

In a number of recent papers Duncan Pritchard argues that virtue epistemology’s central ability condition—one knows that p if and only if one has attained cognitive success (true belief) because of the exercise of intellectual ability—is neither necessary nor sufficient for knowledge. This paper discusses and dismisses a number of responses to Prit...

Pritchard (Synthese 175,133–51, 2010) and Vaesen (Synthese forthcoming) have recently argued that robust virtue epistemology does not square with the extended cognition thesis that has enjoyed an increasing degree of popularity in recent philosophy of mind. This paper shows that their arguments fail. The relevant cases of extended cognition pose no...

In Knowledge and the State of Nature Edward Craig defends the thesis that the function of the concept of knowledge is to flag good informants. This paper aims to show that Craig's thesis (CT) is false. In order to establish this, I will point to some data that CT fails to explain in a satisfactory manner. I will then introduce an alternative thesis...

This paper addresses the argument from ‘contextualist cases’—such as for instance DeRose’s Bank cases—to attributor contextualism. It is argued that these cases do not make a decisive case against invariantism and that the debate between contextualists and invariantists will have to be settled on broader theoretical grounds.

This paper revisits a puzzle that arises for theories of knowledge according to which one can know on the basis of merely inductive grounds. No matter how strong such theories require inductive grounds to be if a belief based on them is to qualify as knowledge, there are certain beliefs (namely, about the outcome of fair lotteries) that are based o...

In Learning from Words Jennifer Lackey professes to revolutionize the epistemology of testimony in at least two crucial ways. First, she claims to show that the widely held thesis that testimony can only transmit knowledge/warrant is false, because in fact knowledge/warrant can be generated by testimony. Secondly, she denies that reductionism and n...

This chapter looks at one - perhaps the only - theoretical view to which, on the face of it, the knowability principle is of central importance. It then considers two deflationary responses to Fitch's argument on behalf of defenders of this view. A 'deflationary' response to the argument refers to a proposal which proceeds by weakening, on a princi...

This paper raises a problem for so-called safetybased conceptions of knowledge: It is argued that none of the versions of the safety condition that can be found in the literature succeeds in identifying a necessary condition on knowledge. Furthermore, reason is provided to believe that the argument generalizes at least in the sense that there can b...

We offer a novel resolution to Fitch's puzzle, one that proceeds by employing a weakened version of the factivity principle for knowledge. We argue that this weakening of factivity is in the spirit of anti-realism and show that by weakening this principle we are thereby able to motivate the weakening of a second principle which is appealed to in Fi...

This thesis addresses the problem of the analysis of knowledge. The persistent failure of analyses of knowledge in terms of necessary and sufficient conditions is used to motivate exploring alternative approaches to the analytical problem. In parallel to a similar development in the theory of truth, in which the persistent failure to provide a sati...
