Two important philosophical questions about assertion concern its nature and normativity. This article defends the optimism about the constitutive norm account of assertion and sets out a constitutivity thesis that is much more modest than that proposed by Timothy Williamson. It starts by looking at the extant objections to Williamson’s Knowledge Account of Assertion (KAA) and argues that they fail to hit their target in virtue of imposing implausible conditions on engaging in norm-constituted activities. Second, it makes a similar proposal and shows how it does better than the competition. It suggests that Knowledge Norm of Assertion (KNA) is not constitutive of the speech act of assertion in the same way in which rules of games are constitutive, and thus KAA comes out as too strong. The final section embarks on a rescue mission on behalf of KAA; it puts forth a weaker, functionalist constitutivity thesis. On this view, KNA is etiologically constitutively associated with the speech act of assertion, in virtue of its function of generating knowledge in hearers.

The investigation of epistemic virtues, such as curiosity, open-mindedness, intellectual courage and intellectual humility is a growing trend in epistemology. An underexplored question in this context is: what is the relationship between these virtues and other types of virtue, such as moral or prudential virtue? This paper argues that, although there is an intuitive sense in which virtues such as intellectual courage and open-mindedness have something to do with the epistemic domain, on closer inspection it is not clear to what extent they should be understood as genuine epistemic virtues. We draw a distinction between epistemic virtues and virtues with epistemic content and provide reason to believe that the aforementioned virtues are moral virtues with epistemic content rather than bona fide epistemic virtues. The upshot is that there are far fewer epistemic virtues out there than commonly assumed.

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 solution to the lottery paradox must reject (i) as versions of the paradox can be generated without appeal to either (ii) or (iii) and proposes a new solution to the paradox in terms of a novel account of justified believability.

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 modal accounts), at least so long as the presupposition is in place. I then look at a couple of recent accounts of knowledge that drop the presupposition and expressly allow the relevant processes to extended beyond the knower's skin. While these accounts can handle the problem case, they encounter difficulties elsewhere: extension occurs too easily and so the accounts predict knowledge where they ought not. Finally, I offer a novel way of extending epistemology and argue that it can steer clear of the problems on both sides.

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 a novel knowledge based account of understanding. More specifically, it proposes an account of maximal understanding of a given phenomenon in terms of fully comprehensive and maximally well-connected knowledge of it and of degrees of understanding in terms of approximations to such knowledge. It is completed by a contextualist semantics for outright attributions of understanding according to which an attribution of understanding is true of one just in case one knows enough about it to perform some contextually determined task. It is argued that this account has an edge over both its explanationist and manipulationist competitors.

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 version of mentalism Bird (2007). This paper offers a knowledge first version of virtue epistemology and argues that it is preferable to its knowledge first epistemological rivals: only knowledge first virtue epistemology manages to steer clear of a number of problems that its competition encounters.

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 success from ability, the pressure is on to treat Fake Barn cases as cases of knowledge. The challenge virtue epistemology faces is to explain the intuitive lack of knowledge in Fake Barn cases, whilst holding on to the core claim that knowledge is success from ability. Ernest Sosa's version of virtue epistemology promises to rise to this challenge. Sosa distinguishes two types of knowledge, animal knowledge and reflective knowledge. He argues that while animal knowledge is present in Fake Barn cases, reflective knowledge is absent and ventures to explain the intuition of ignorance by the absence of reflective knowledge. This paper argues that Sosa's treatment of Fake Barn cases fails as it commits Sosa to a number of highly counterintuitive results elsewhere in epistemology.

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 as what I call an ‘impure’ version of virtue epistemology, according to which the competence condition is supplemented by an additional (safety) condition; like Sosa's 2007, 2010 view, it construes the ‘because’ relation at issue in the competence condition in terms of competence manifestation. I argue that this virtue epistemology can steer clear of a number of old and new problems that arise for its rivals on both sides.

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 new problem for robust virtue epistemology. It is shown that Pritchard’s and Vaesen’s cases can be dealt with in familiar ways by a number of virtue theories of knowledge.

It has recently been argued that, contrary to first appearances, knowledge is not distinctively valuable. The argumentative strategy of value sceptics in epistemology is to identify a challenge that any satisfactory account of the distinctive value of knowledge will have to meet and to argue that no viable theory of knowledge does the job. This paper argues that the value sceptical argument is unsuccessful in that it does not establish that a virtue epistemological account of the value of knowledge fails.

This paper raises a problem for so-called safety-based 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 be no version of the safety condition that does justice to the considerations motivating a safety condition whilst, at the same time, being requisite for knowledge.

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 on even stronger inductive grounds, while, intuitively, they do not qualify as knowledge. This paper discusses what is often regardedas the most promising classical invariantist solution to the puzzle, namely, that beliefs about the outcomes of fair lotteries do not qualify as knowledge because they are too lucky to do so (or, relatedly, because they do not satisfy a safety condition on knowledge), while other beliefs based on potentially weaker inductive grounds are not too lucky (or, relatedly, because they are safe). A case is presented that shows that this solution to the puzzle is actually not viable. It is argued that there is no obvious alternative solution in sight and that therefore the puzzle still awaits a classical invariantist solution.

This paper considers two deflationary responses to the Fitch argument on behalf of the semantic anti-realistthat is, two responses which aim to evade the conclusion of that argument by, on a principled basis, weakening one of the principles essentially employed. The first deflationary approach that is consideredwhich proceeds by weakening the factivity principle for knowledgeis shown to be ultimately unpromising, but a second approachwhich proceeds by weakening the knowability principle that is at the heart of semantic anti-realismis shown to have considerable prima facie appeal. It is then argued that some key objections that one might raise for this approach are on closer inspection ineffective

According to the achievement account of the value of knowledge, knowledge is finally valuable because it is a species of a finally valuable genus, achievement. The achievement account is said to solve Pritchard's tertiary value problem, the problem of showing that knowledge enjoys a different kind of value than mere true belief. This paper argues, first, that AA fails to solve TVP, and, second, that Pritchard's motivations for TVP are inadequate. They do, however, motivate a weaker value problem, one that can be solved by showing that knowledge is weakly superior to mere true belief. Finally, third, we argue that knowledge does enjoy this form of weak superiority. Since this argument rests on AA's key species-genus claim, AA can retain the upper hand in the debate.

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 satisfactory answer to the question as to what the nature of truth is has led to the exploration of deflationary and minimalist approaches to the theory of truth, the prospects for deflationary and minimalist approaches to the theory of knowledge are investigated. While it is argued that deflationary approaches are ultimately unsatisfactory, a minimalist approach to epistemology, which characterises the concept of knowledge by a set of platitudes about knowledge, is defended. The first version of a minimalist framework for the theory of knowledge is developed. Two more substantive developments of the minimalist framework are discussed. In the first development a safety condition on knowledge is derived from the minimalist framework. Problems for this development are discussed and solved. In the second development, an ability condition is derived from the minimalist framework. Reason is provided to believe that, arguably, the ability condition can avoid the problems that beset traditional analyses of knowledge. It is also shown that even if this argument fails, minimalist approaches to epistemology may serve to provide a functional definition of knowledge. Reason is thus provided to believe that minimalist approaches to epistemology can make progress towards addressing the problem of the analysis of knowledge
