Traditional accounts of justification can be characterized as trying to analyze justification in such a way that having a justified belief brings with it assurance of truth. The internalist offers a demanding requirement on justification: one's having a justified belief requires that one see what the belief has going for it. Externalists worry that the internalist's narrow conception of justification will lead to unacceptably radical and implausible skepticism. According to the externalist, one need not know what a belief has going (...) for it in order for that belief to be justified. Externalism, though, comes with its own problems. Ernest Sosa has attempted to bridge the divide between internalism and externalism by pairing the strengths of internalism with the strengths of externalism. Sosa distinguishes two kinds of knowledge: animal knowledge that is essentially externalist in character and reflective knowledge that is intended to capture our best intellectual procedure in regards to knowledge. On Sosa's view, one gains reflective knowledge by building upon animal knowledge. As a result, Sosa's view seems to illustrate a bottom-up approach to the analysis of knowledge : reflective knowledge is the result of animal knowledge and some other epistemic factor. My project, in contrast to Sosa's, is to argue that one should start with an account of ideal justification and then proceed by loosening the standards on ideal justification in an effort to develop the possibility of non- ideal kinds of justification. The view that I will develop will adopt Sosa's strategy of distinguishing kinds of knowledge, but will result in a top-down approach to the analysis of justification. Instead of starting with an undemanding standard and layer levels on top, I will start with an ideal standard and strip layers away. I will also argue that my view has some important advantages over Sosa's. Not only does Sosa's view seem to run into many of the problems that threaten externalism, but his view is incapable of offering the kind of assurance that the internalist is after. The view I develop will maintain the internalist's interest in assurance while also providing a response to some of the skeptical problems that have plagued internalists. If my project is successful, then, even if the justification that results in many of the cases I will be exploring is not ideal, we can use these conceptions of justification to help explicate how one might have justified beliefs about a great number of things. The essentially internalist account that I have offered will not only illustrate a serious approach to dealing with skepticism, but it will also capture how many of our commonsensically justified beliefs are in fact justified.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

The internalism /externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of knowledge and epistemic justification? It is generally held that if a positive epistemic status obtains, this is not a brute fact. Rather if a belief is, for example, justified, it is justified in virtue of some further condition obtaining. What has been called epistemic internalism holds, as the label suggests, is that all the (...) relevant factors that determine justification must be “internal”. Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position. In addition to classical formulations, more recent formulations will be discussed, concluding with a discussion of an emerging position known as “Epistemological Disjunctivism”, which its advocates claim preserves the most important features of more traditional forms of internalism, while avoiding their difficulties. Epistemological Disjunctivism is particularly worthy of attention since if true, it promises to bridge internalist and externalist epistemologies, bringing a rapprochement to two sides of what may otherwise appear a deep and intractable debate about the fundamental nature of epistemology.

While epistemic justification is a central concern for both contemporary epistemology and philosophy of science, debates in contemporary epistemology about the nature of epistemic justification have not been discussed extensively by philosophers of science. As a step toward a coherent account of scientific justification that is informed by, and sheds light on, justificatory practices in the sciences, this paper examines one of these debates—the internalist-externalist debate—from the perspective of objective accounts of scientific evidence. In particular, we focus on Deborah Mayo’s (...) error-statistical theory of evidence because it is a paradigmatically objective theory of evidence that is strongly informed by methodological practice. We contend that from the standpoint of such an objective theory of evidence, justification in science has both externalist and internalist characteristics. In reaching this conclusion, however, we find that the terms of the contemporary debate between internalists and externalists have to be redefined to be applicable to scientific contexts. (shrink)

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

Virtue reliabilists argue that an agent can only gain knowledge if she responsibly employs a reliable belief-forming process. This in turn demands that she is either aware that her process is reliable or is sensitive to her process’s reliability in some other way. According to a recent argument in the philosophy of mind, sometimes a cognitive mechanism (i.e. precision estimation) can ensure that a belief-forming process is only employed when it’s reliable. If this is correct, epistemic responsibility can sometimes be (...) explained entirely on the subpersonal level. In this paper, I argue that the mechanism of precision estimation–the alleged new variety of epistemic responsibility–is a more ubiquitous phenomenon than epistemic responsibility. I show that precision estimation operates at levels that are not always concerned with the epistemic domain. Lastly, I broaden this argument to explain how all subpersonal epistemologies are likely to fall prey to the problem of demarcating cognitive agency and the problem of attributing beliefs. (shrink)

I will argue that internalism about justification entails the apparently absurd conclusion that it is possible to know specific facts about the external world—for example, that there is a tree in the quad—on the basis of introspection and a priori reflection. After a brief characterization of internalism (§1), I will set out the problem (§2). I will then discuss three replies: one that denies the form of doxastic voluntarism involved in the problem (§3), one that denies that knowledge of higher-order (...) facts about justification can justify corresponding first-order beliefs (§4), and, finally, one that involves biting the bullet (§5). I will argue that each reply fails. (shrink)

It is commonly observed that we live in an increasingly polarised world. Strikingly, we are polarised not only about political issues, but also about scientific issues that have political implications, such as climate change. This raises two questions. First, why are we so polarised over these issues? Second, does this mean our views about these issues are all equally ir/rational? In this chapter I explore both questions. Specifically, I draw on the literature on ideologically motivated reasoning to develop an answer (...) to the first question. Put briefly, we exhibit “directional biases” in our information processing: we try to assimilate new information into our existing webs of beliefs. This means that those who are predisposed to accept the case for climate change end up accepting it, whereas those who are predisposed to reject it end up rejecting it. Based on this answer, I then address the second question. I look at some reasons for thinking that, because we all exhibit such biases in our thinking, we are all equally rational (or, as the case may be, irrational). I also suggest some ways you might try reject these reasons. (shrink)

Is there a distinctively epistemic kind of blame? It has become commonplace for epistemologists to talk about epistemic blame, and to rely on this notion for theoretical purposes. But not everyone is convinced. Some of the most compelling reasons for skepticism about epistemic blame focus on disanologies, or asymmetries, between the moral and epistemic domains. In this paper, I defend the idea that there is a distinctively epistemic kind of blame. I do so primarily by developing an account of the (...) nature of epistemic blame. My account draws on a prominent line of theorizing in moral philosophy that ties blame to our relationships with one another. I argue that with my account of epistemic blame on hand, the most compelling worries about epistemic blame can be deflated. There is a distinctively epistemic kind of blame. (shrink)

Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our (...) theories of epistemic rationality should accommodate misleading evidence, the debate over the relationship between complying with requirements and deserving particular appraisals, and the debate over whether normative ignorance can excuse. Part 1 shows how three apparently plausible claims about epistemic rationality generate a puzzle when agents have misleading evidence about what rationality requires. Part 2 solves this puzzle by distinguishing between evaluations of requirement and appraisal and rejecting the idea that one is required to conform to the Enkratic Principle. I argue instead that complying with the Enkratic Principle provides defeasible evidence that the agent should be positively appraised. One of the consequences of this solution is that false normative beliefs can sometimes excuse agents from negative appraisal they would otherwise deserve for violating requirements. Part 3 defends the view that false normative belief can sometimes excuse against the rival views that false normative belief always excuses, and that false normative belief never excuses. I argue that false normative belief can sometimes excuse violations of requirements, when it is the case that the agent has done what it is reasonable to expect of her. (shrink)

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

It has recently been argued that beliefs formed on the basis of implicit biases pose a challenge for accessibilism, since implicit biases are consciously inaccessible, yet they seem to be relevant to epistemic justification. Recent empirical evidence suggests, however, that while we may typically lack conscious access to the source of implicit attitudes and their impact on our beliefs and behaviour, we do have access to their content. In this paper, I discuss the notion of accessibility required for this argument (...) to work vis-à-vis these empirical results and offer two ways in which the accessibilist could meet the challenge posed by implicit biases. Ultimately both strategies fail, but the way in which they do, I conclude, reveals something general and important about our epistemic obligations and about the intuitions that inform the role of implicit biases in accessibilist justification.

Cognitive integration is a defining yet overlooked feature of our intellect that may nevertheless have substantial effects on the process of knowledge-acquisition. To bring those effects to the fore, I explore the topic of cognitive integration both from the perspective of virtue reliabilism within externalist epistemology and the perspective of extended cognition within externalist philosophy of mind and cognitive science. On the basis of this interdisciplinary focus, I argue that cognitive integration can provide a minimalist yet adequate epistemic norm of (...) subjective justification: so long as the agent’s belief-forming process has been integrated in his cognitive character, the agent can be justified in holding the resulting beliefs merely by lacking any doubts there was something wrong in the way he arrived at them. Moreover, since both externalist philosophy of mind and externalist epistemology treat the process of cognitive integration in the same way, we can claim that epistemic cognitive characters may extend beyond our organismic cognitive capacities to the artifacts we employ or even to other agents we interact with. This move is not only necessary for accounting for advanced cases of knowledge that is the product of the operation of epistemic artifacts or the interactive activity of research teams, but it can further lead to interesting ramifications both for social epistemology and philosophy of science.

A prominent objection to the knowledge norm of belief is that it is too demanding or too strong. The objection is commonly framed in terms of the idea that there is a tight connection between norm violation and the appropriateness of criticism or blame. In this paper I do two things. First, I argue that this way of motivating the objection leads to an impasse in the epistemic norms debate. It leads to an impasse when knowledge normers invoke excuses to (...) explain away a prima facie connection between blamelessness and justified belief. Second, I argue that a way out of the impasse becomes available when we take a closer look at some distinctions in the theory of responsibility. There are at least three different notions of responsibility relevant here. I argue that a weaker notion of responsibility – attributability – should be used to motivate the objection that the knowledge norm of belief is too strong. Insofar as the proposal motivates the objection without appeal to blamelessness, it opens up space to move beyond the impasse. (shrink)

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

Internalists face the following challenge: what is it about an agent's internal states that explains why only these states can play whatever role the internalist thinks these states are playing? Internalists have frequently appealed to a special kind of epistemic access that we have to these states. But such claims have been challenged on both empirical and philosophical grounds. I will argue that internalists needn't appeal to any kind of privileged access claims. Rather, internalist conditions are important because of the (...) way in which we expect them to act as causal mediators between states of the world, on the one hand, and our beliefs and actions on the other.

Mainstream epistemologists have recently made a few isolated attempts to demonstrate the particular ways, in which specific types of knowledge are partly social. Two promising cases in point are Lackey’s dualism in the epistemology of testimony and Goldberg’s process reliabilist treatment of testimonial and coverage-support justification. What seems to be missing from the literature, however, is a general approach to knowledge that could reveal the partly social nature of the latter anytime this may be the case. Indicatively, even though Lackey (...) :345–361, 2007) has recently launched an attack against the Credit Account of Knowledge on the basis of testimony, she has not classified her view of testimonial knowledge into any of the alternative, general approaches to knowledge. Similarly, even if Goldberg’s attempt to provide a process reliabilist explanation of the social nature of testimonial knowledge is deemed satisfactory, his attempt to do the same in the case of coverage-support justification does not deliver the requisite result. This paper demonstrates that CAK can in fact provide, pace Lackey’s renunciation of the view, a promising account of the social nature of both testimonial and coverage-supported knowledge. Additionally, however, it can display further explanatory power by also revealing the social nature of knowledge produced on the basis of epistemic artifacts. Despite their disparities, all these types of knowledge count as partly social in nature, because in all these cases, according to CAK, the epistemic credit for the individual agent’s true belief must spread between the individual agent and certain parts of her epistemic community. Accordingly, CAK is a promising candidate for providing a unified approach to several and, perhaps all possible, instances of what we may call ‘weak epistemic anti-individualism’ within mainstream epistemology: i.e., the claim that the nature of knowledge can occasionally be both social and individual at the same time.

Two arguments against the compatibility of epistemic internalism and content externalism are considered. Both arguments are shown to fail, because they equivocate on the concept of justification involved in their premises. To spell out the involved equivocation, a distinction between subjective and objective justification is introduced, which can also be independently motivated on the basis of a wide range of thought experiments to be found in the mainstream literature on epistemology. The subjective/objective justification distinction is also ideally suited for providing (...) new insights with respect to central issues within epistemology, including the internalism/externalism debate and the New Evil Demon intuition.

Van Fraassen has recently argued that empiricism can be construed as a stance, involving commitments, attitudes, values, and goals, in addition to beliefs and opinions. But this characterisation emerges from his recognition that to be an empiricist can not be to believe, or decide to commit to belief in, a foundational proposition, without removing any basis for a non-dogmatic empiricist critique of other philosophical approaches, such as materialism. However, noticeable by its absence in Van Fraassen's discussions is any mention of (...) Bartley's ‘pancritical rationalism’, for Bartley offers a cohesive argument that genuine dogmatism lies precisely in the act of commitment to an idea. The consequence of denying this, he thinks, is an opening of the floodgates to irrationalism: if to rely on reasoned argument in decision-making is fundamentally an act of faith, then there is a tu quoque – “I simply have a different faith” – that may be employed by those who wish to shield their views from criticism. This raises the following question: why should it be any less dogmatic to adopt particular commitments, attitudes, values, and goals, rather than a particular belief or opinion, come what may? And if Bartley is right that there is only one non-dogmatic attitude – the critical attitude – then why might this not be adopted by an empiricist, a materialist, a metaphysician, or anyone else?

Internalists and externalists in epistemology continue to disagree about how best to understand epistemic concepts such as justification or warrant or knowledge. But there has been some movement towards agreement. Two of the most prominent rationales for the internalist position have been subjected to severe criticism by externalists: the idea that justification should be understood deontologically and the thought that justification consists in having a reason in the form of another belief. It would not be accurate to say that all (...) internalists have responded to such criticism by distancing themselves from these rationales for their position. Nevertheless some have. But despite the growing disenchantment with these two motivations for internalism, internalists continue to find the externalist position extremely unattractive. One main reason for this persistent resistance to externalism is a third rationale that is, perhaps, the most influential of the driving forces behind internalism. (shrink)

What does it take to convert the deliverances of an extended cognitive process into knowledge? It is argued that virtue epistemology, at least of an epistemic externalist kind, offers the resources to satisfactorily answer this question, provided that one rids the view of its implicit commitment to epistemic individualism. Nonetheless, it is also claimed that while virtue reliabilism can accommodate extended cognition, there are limits to the extent to which virtuous epistemic standings can be extended. In particular, it is argued (...) that it is in the nature of intellectual virtue to be directed at non-extended epistemic standings. This point has important implications for an extended virtue epistemology, as is illustrated by considering how this point plays out in the context of the contemporary debate regarding the epistemology of education.

Two different versions of epistemological disjunctivism have recently been upheld in the literature: a traditional, Justified True Belief Epistemological Disjunctivism (JTBED) and a Knowledge First Epistemological Disjunctivism (KFED). JTBED holds that factive reasons of the form “S sees that p” provide the rational support in virtue of which one has perceptual knowledge, while KFED holds that factive reasons of the form “S sees that p” just are ways of knowing that p which additionally provide justification for believing that p. We (...) argue that both accounts remain ultimately unsatisfactory. JTBED faces two formidable problems: first, it cannot account for animal knowledge, and, second, it does not offer a satisfactory account of how we access factive reasons. Although KFED can solve these two problems, it has some problems of its own. While intuitively knowledge is logically stronger than justified belief, on KFED it turns out to be weaker: knowledge does not entail justified belief, but justified belief does entail knowledge. Nevertheless, disjunctivists are right on at least a couple of points: we standardly justify our perceptual beliefs by appealing to factive reasons such as seeing that p and so factive reasons ought to play some role in our theory of justification. In addition, KFED’s account of our access to factive reasons also is spot on. Rather than going disjunctivist, these insights can be suitably incorporated into a Knowledge First Virtue Epistemology (KFVE). (shrink)

Strong epistemic anti-individualism—i.e., the claim that knowledge can be irreducibly social—is increasingly debated within mainstream and social epistemology. Most existing approaches attempt to argue for the view on the basis of aggregative analyses, which focus on the way certain groups aggregate the epistemic attitudes of their members. Such approaches are well motivated, given that many groups to which we often ascribe group knowledge—such as juries and committees—operate in this way. Yet another way that group knowledge can be generated is on (...) the basis of epistemic collaborations, such as scientific research teams and Transactive Memory Systems. To produce knowledge, epistemic collaborations rely heavily on the mutual interactions of their group members. This is a distinctive feature of epistemic collaborations that renders them resistant to aggregative analyses. To accommodate this kind of group knowledge, the paper combines virtue reliabilism with the hypothesis of distributed cognition in order to introduce the hybrid approach of distributed virtue reliabilism. On this view, beliefs produced by epistemic collaborations entertain positive epistemic standing in virtue of the mutual interactions of their group members; this positive epistemic standing is a collective property; epistemic collaborations qualify as epistemic group agents; collaborative knowledge is a special kind of group knowledge, motivating strong epistemic anti-individualism in a distinctive way.

Ordinary Language Philosophy has largely fallen out of favour, and with it the belief in the primary importance of analyses of ordinary language for philosophical purposes. Still, in their various endeavours, philosophers not only from analytic but also from other backgrounds refer to the use and meaning of terms of interest in ordinary parlance. In doing so, they most commonly appeal to their own linguistic intuitions. Often, the appeal to individual intuitions is supplemented by reference to dictionaries. In recent times, (...) Internet search engine queries for expressions of interest have become quite popular. Apparently, philosophers attempt to surpass the limits of their own linguistic intuitions by appealing to experts or to factual uses of language. I argue that this attempt is commendable but that its execution is wanting. Instead of appealing to dictionaries or Internet queries, philosophers should employ computer-based linguistic corpora in order to confirm or falsify hypotheses about the factual use of language. This approach also has some advantages over methods employed by experimental philosophers. If the importance of ordinary language is stressed, the use of linguistic corpora is hardly avoidable.

This paper argues that for someone to know proposition p inferentially it is not enough that his belief in p and his justification for believing p covary with the truth of p through a sphere of possibilities. A further condition on inferential knowledge is that p's truth-maker is identical with, or causally related to, the state of affairs the justification is grounded in. This position is dubbed ‘identificationism.’.

We aim to develop a form of debunking argument according to which an agent’s belief is undermined if the reasons she gives in support of her belief are best explained as rationalizations. This approach is a more sophisticated form of what Shaun Nichols has called best-explanation debunking, which he contrasts with process debunking, i.e., debunking by means of showing that a belief has been generated by an epistemically defective process. In order to develop our approach, we identify an example of (...) such a best-explanation debunking argument in Joshua Greene’s attack on deontology. After showing that this argument is not an instance of process debunking, we offer our best-explanation approach as a generalization of Greene’s argument. Finally, we defend our approach by showing that it is not susceptible to some criticisms that Nichols has leveled against a less sophisticated form of best-explanation debunking. (shrink)

In Weaving the Web, Berners-Lee defines Social Machines as biotechnologically hybrid Web-processes on the basis of which, “high-level activities, which have occurred just within one human’s brain, will occur among even larger more interconnected groups of people acting as if the shared a larger intuitive brain”. The analysis and design of Social Machines has already started attracting considerable attention both within the industry and academia. Web science, however, is still missing a clear definition of what a Social Machine is, which (...) has in turn resulted in several calls for a “philosophical engineering” ; Halpin et al. 2010). This paper is a first attempt to respond to this call, by combining contemporary philosophy of mind and cognitive science with epistemology. The idea of philosophical engineering implies that a sufficiently good conception of Social Machines should be of both theoretical and practical advantage. To demonstrate how the present approach can satisfy both objectives it will be used in order to address one of Wikipedia’s most worrying concerns—i.e., the current and ongoing decline in the number of its active contributors.

The thesis that knowledge is a partly evaluative concept is now a widespread view in epistemology, informing some prominent debates in the field. Typically, the view is embraced on the grounds that justification is a necessary condition for knowledge and a normative concept — a reasonable motivation. However, the view also has counterintuitive implications, which have been neglected. In particular, it implies that J.L. Mackie’s error-theory of value entails global epistemic scepticism and that any true knowledge claim suffices to prove (...) the error-theory is false. In this paper, I elaborate these difficulties and address objections at length. (shrink)

Abstract In this paper I examine two claims that support the thesis that chimpanzees are substantive epistemic subjects. First, I defend the claim that chimpanzees are evidence gatherers (broadly construed to include the capacity to gather and use evidence). In the course of showing that this claim is probably true I will also show that, in being evidence gatherers, chimpanzees engage in a recognizable epistemic activity. Second, I defend the claim that chimpanzees achieve a degree of epistemic success while engaging (...) in epistemic activity. Typically humans qualify as substantive epistemic subjects. Again, typically, knowledge plays an integral role in intentional human behaviour. As a consequence of defending the claims that chimpanzees are evidence gatherers and achieve a degree of epistemic success while engaging in such epistemic activities, I will also have shown how knowledge plays an integral role in intentional chimpanzee behaviour. The importance of these arguments does not wholly reside in the significance of knowledge explaining some chimpanzee behaviour. Treatments of animal knowledge in the literature tend to go in one of two directions: either the treatment embraces reliabilism and so construes animal knowledge as reliably produced true beliefs (or, if not beliefs, the relevant analogue for non-linguistic animals), or it embraces an anthropocentric stance that treats animals as knowers only when they find themselves behaving in circumstances that, were it true of humans, would imply the presence of causally efficacious knowledge. What I offer here is another way of understanding non-linguistic animals, in this case chimpanzees, as knowers. (shrink)
