According to Duncan Pritchard’s version of epistemological disjunctivism, in paradigm cases of perceptual knowledge, one’s knowledge that p is grounded in one’s seeing that p, and one can, by reflection alone, come to know that they see that p. In this paper, I argue that the epistemic conception of introspective indiscriminability is incompatible with epistemological disjunctivism, so understood. This has the consequence that theories of the nature of sensory experience which accept the epistemic conception of introspective indiscriminability—such as phenomenal character (...) disjunctivism and certain forms of naïve realism—are inconsistent with epistemological disjunctivism, so understood. I then argue that proponents of epistemological disjunctivism face a formidable challenge explaining in what sense, if any, one can have purely reflective knowledge of their factive rational support.

I consider the ‘inferentialist’ thesis that whenever a mental state rationally justifies a belief it is in virtue of inferential relations holding between the contents of the two states. I suggest that no good argument has yet been given for the thesis. I focus in particular on Williamson (2000) and Ginsborg (2011) and show that neither provides us with a reason to deny the plausible idea that experience can provide non-inferential justification for belief. I finish by pointing out some theoretical (...) costs and tensions associated with endorsing inferentialism. (shrink)

According to a classic but nowadays discarded philosophical theory, perceptual experience is a complex of nonconceptual sensory states and full-blown propositional beliefs. This classical dual-component theory of experience is often taken to be obsolete. In particular, there seem to be cases in which perceptual experience and belief conflict: cases of known illusions, wherein subjects have beliefs contrary to the contents of their experiences. Modern dual-component theories reject the belief requirement and instead hold that perceptual experience is a complex of nonconceptual (...) sensory states and some other sort of conceptual state. The most popular modern dual-component theory appeals to sui generis propositional attitudes called ‘perceptual seemings’. This article argues that the classical dual-component theory has the resources to explain known illusions without giving up the claim that the conceptual components of experience are beliefs. The classical dual-component view, though often viewed as outdated and implausible, should be regarded as a serious contender in contemporary debates about the nature of perceptual experience.

Recent research in social psychology suggests that many beliefs are formed as a result of implicit biases in favour of members of certain groups and against members of other groups. This article argues that beliefs of this sort present a counterexample to accessibilism in epistemology because the position cannot account for how the epistemic status of a belief that is the result of an implicit bias can differ from that of a counterpart belief that is the result of an unbiased (...) response to the available evidence.

It has been suggested, by Michael Bishop, that empirical evidence on human reasoning poses a threat to the internalist account of epistemic responsibility, which he takes to associate being epistemically responsible with coherence, evidence-fitting and reasons-responsiveness. Bishop claims that the empirical data challenges the importance of meeting these criteria by emphasising how it is possible to obtain true beliefs by diverging from them. He suggests that the internalist conception of responsibility should be replaced by one that properly reflects how we (...) can reliably obtain true beliefs. In this paper I defend the internalist account by arguing that Bishop has misinterpreted the relevance of the empirical evidence to the philosophical theory. I argue that the empirical data actually provides support for the idea that, if we want to obtain true beliefs by being responsible, we should aim to meet the criteria that internalists associate with epistemic responsibility.

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

This article surveys work in epistemology since the mid-1980s. It focuses on contextualism about knowledge attributions, modest forms of foundationalism, and the internalism/externalism debate and its connections to the ethics of belief.

The recent literature on the theory of knowledge has taken a distinctive turn by focusing on the role of the cognitive and intellectual virtues in the acquisition of knowledge. The main contours and motivations for such virtue-theoretic accounts of knowledge are here sketched and it is argued that virtue epistemology in its most plausible form can be regarded as a refined form of reliabilism, and thus a variety of epistemic externalism. Moreover, it is claimed that there is strong empirical support (...) in favour of the virtue epistemic position so understood, and an empirical study regarding the cognitive processes employed by medical experts in their diagnosis and treatment of epilepsy is cited in this regard. In general, it is argued that one can best account for 'expert' knowledge in terms of a virtue-theoretic epistemology that retains key reliabilist features. It is thus shown that understanding knowledge along virtue-theoretic lines has important implications for our understanding of how knowledge is acquired, and thus for the philosophy of education. (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.

The aim of this paper is to look at what a parallel deflationist program might be in the theory of knowledge and examine its prospect. In what follows I will simplify matters slightly by focussing on empirical knowledge rather than knowledge in general, though most of what I have to say ought to be applicable, mutatis mutandis, to knowledge in general. Moreover,note that it is not my aim to offer a full defense of a particular deflationist theory of knowledge, which (...) would go well beyond the scope of this paper, but only to defend the utility of taking the deflationist program as regards the theory of knowledge seriously by showing that there is a plausible deflationist position available that is worthy of further scrutiny.

Epistemic conservatism is the thesis that the mere holding of a belief confers some positive epistemic status on its content. Conservatism is widely criticized on the grounds that it conflicts with the main goal in epistemology to believe truths and disbelieve falsehoods. In this paper I argue for conservatism and defend it from objections. First, I argue that the objection to conservatism from the truth goal in epistemology fails. Second, I develop and defend an argument for conservatism from the perspectival (...) character of the truth goal. Finally, I examine several forceful challenges to conservatism and argue that these challenges are unsuccessful. The first challenge is that conservatism implies the propriety of assertions like ‘I believe p and this is part of my justification for it’. The second challenge argues that conservatism wrongly implies that the identity of an epistemic agent is relevant to the main goal of believing truths and disbelieving falsehoods. The last two challenges I consider are the ‘extra boost’ objection and the conversion objection. Each of these objections helps to clarify the nature of the conservative thesis. The upshot of the paper is that conservatism is an important and viable epistemological thesis. (shrink)

It is a widespread intuition that the coherence of independent reports provides a powerful reason to believe that the reports are true. Formal results by Huemer, M. 1997. “Probability and Coherence Justification.” Southern Journal of Philosophy 35: 463–72, Olsson, E. 2002. “What is the Problem of Coherence and Truth?” Journal of Philosophy XCIX : 246–72, Olsson, E. 2005. Against Coherence: Truth, Probability, and Justification. Oxford University Press., Bovens, L., and S. Hartmann. 2003. Bayesian Epistemology. Oxford University Press, prove that, under (...) certain conditions, coherence cannot increase the probability of the target claim. These formal results, known as ‘the impossibility theorems’ have been widely discussed in the literature. They are taken to have significant epistemic upshot. In particular, they are taken to show that reports must first individually confirm the target claim before the coherence of multiple reports offers any positive confirmation. In this paper, I dispute this epistemic interpretation. The impossibility theorems are consistent with the idea that the coherence of independent reports provides a powerful reason to believe that the reports are true even if the reports do not individually confirm prior to coherence. Once we see that the formal discoveries do not have this implication, we can recover a model of coherence justification consistent with Bayesianism and these results. This paper, thus, seeks to turn the tide of the negative findings for coherence reasoning by defending coherence as a unique source of confirmation. (shrink)

This paper develops and defends a coherentist account of reasons. I develop three core ideas for this defense: a distinction between basic reasons and noninferential justification, the plausibility of the neglected argument against first philosophy, and an emergent account of reasons. These three ideas form the backbone for a credible coherentist view of reasons. I work toward this account by formulating and explaining the basic reasons dilemma. This dilemma reveals a wavering attitude that coherentists have had toward basic reasons. More (...) importantly, the basic reasons dilemma focuses our attention on the central problems that afflict coherentist views of basic beliefs. By reflecting on the basic reasons dilemma, I formulate three desiderata that any viable coherentist account of basic beliefs must satisfy. I argue that the account on offer satisfies these desiderata. (shrink)

The Sellarsian dilemma is a powerful argument against internalistic foundationalist views that aim to end the regress of reasons in experiential states. Laurence BonJour once defended the soundness of this dilemma as part of a larger argument for epistemic coherentism. BonJour has now renounced his earlier conclusions about the dilemma and has offered an account of internalistic foundationalism aimed, in part, at showing the errors of his former ways. I contend that BonJour’s early concerns about the Sellarsian dilemma are correct, (...) and that his latest position does not adequately handle the dilemma. I focus my attention on BonJour’s claim that a nonconceptual experiential state can provide a subject with a reason to believe some proposition. It is crucial for the viability of internalistic foundationalism to evaluate whether this claim is true. I argue it is false. The requirement that the states that provide justification give reasons to a subject conflicts with the idea that these states are nonconceptual. In the final section I consider David Chalmers’s attempt to defend a view closely similar to BonJour’s. Chalmers’s useful theory of phenomenal concepts provides a helpful framework for identifying a crucial problem with attempts to end the regress of reasons in pure experiential states. (shrink)

Recent work by Peijnenburg, Atkinson, and Herzberg suggests that infinitists who accept a probabilistic construal of justification can overcome significant challenges to their position by attending to mathematical treatments of infinite probabilistic regresses. In this essay, it is argued that care must be taken when assessing the significance of these formal results. Though valuable lessons can be drawn from these mathematical exercises (many of which are not disputed here), the essay argues that it is entirely unclear that the form of (...) infinitism that results meets a basic requirement: namely, providing an account of infinite chains of propositions qua reasons made available to agents.

My target is the epistemological dimension of the realism debate. After establishing a stance voluntarist framework with a Jamesian background, drawing mostly on Wylie, Chakravarty, and van Fraassen, I argue that current voluntarists are too permissive. I show that especially various anti-realist stances but also some realist and selective realist stances block themselves from refutation by the history of science. I argue that such stances should be rejected. Finally, I propose that any disagreement that cannot be resolved by this strategy (...) frequently boils down to an epistemic value disagreement about balancing the truth-goal. (shrink)

We present a unified approach for investigating rational reasoning about basic argument forms involving indicative conditionals, counterfactuals, and basic quantified statements within coherence-based probability logic. After introducing the rationality framework, we present an interactive view on the relation between normative and empirical work. Then, we report a new experiment which shows that people interpret indicative conditionals and counterfactuals by coherent conditional probability assertions and negate conditionals by negating their consequents. The data support the conditional probability interpretation of conditionals and the (...) narrow-scope reading of the negation of conditionals. Finally, we argue that coherent conditional probabilities are important for probabilistic analyses of conditionals, nonmonotonic reasoning, quantified statements, and paradoxes. (shrink)

Epistemic deontology maintains that our beliefs and degrees of belief are open to deontic evaluations—evaluations of what we ought to believe or may not believe. Some philosophers endorse strong internalist versions of epistemic deontology on which agents can always access what determines the deontic status of their beliefs and degrees of belief. This paper articulates a new challenge for strong internalist versions of epistemic deontology. Any version of epistemic deontology must face William Alston’s argument. Alston combined a broadly voluntarist conception (...) of responsibility, on which ought implies can, with doxastic involuntarism, the position that our beliefs are not under our control. Together, those views imply that epistemic deontology is false. A promising response to Alston’s argument is to embrace a compatibilist account of control—specifically a reason-responsive version of compatibilism—and use it to criticism his doxastic involuntarism. I argue that while reason-responsive compatibilism about control does undermine Alston’s argument, it comes at a cost. Specifically, it is inconsistent with strong internalist versions of epistemic deontology. The surprising upshot is that so long as we retain a voluntarist conception of responsibility, we have reason for rejecting strong internalist versions of epistemic deontology. (shrink)

Skeptical theism is a family of responses to arguments from evil. One important member of that family is Stephen Wykstra’s CORNEA-based criticism of William Rowe’s arguments from evil. A cornerstone of Wykstra’s approach is his CORNEA principle. However, a number of authors have criticized CORNEA on various grounds, including that it has odd results, it cannot do the work it was meant to, and it problematically conflicts with the so-called common sense epistemology. In this paper, I explicate and defend a (...) CORNEA principle. After sketching a brief argument for it, I show how it can be acquitted of these recent charges. (shrink)

In a series of papers, Adam Leite has developed a novel view of justification tied to being able to responsibly justify a belief. Leite touts his view as faithful to our ordinary practice of justifying beliefs, providing a novel response to an epistemological problem of the infinite regress, and resolving the “persistent interlocutor” problem. Though I find elements of Leite’s view of being able to justify a belief promising, I hold that there are several problems afflicting the overall picture of (...) justification. In this paper, I argue that despite its ambitions, Leite’s view fails to solve the persistent interlocutor problem and does not avoid a vicious regress. (shrink)

Most epistemologists maintain that true beliefs are of final epistemic value. However, Richard Feldman is a rare philosopher who is skeptical that true beliefs are of final epistemic value. The aim of this paper is to evaluate Feldman’s criticisms. I’ll argue that Feldman’s arguments ultimately turn on a view about the relation between epistemic duties and epistemic value that is implausible and underdeveloped.

Many philosophers believe that true belief is of epistemic value, but that knowledge is of even more epistemic value. Some claim that this surplus value is instrumentally valuable to the value of true belief. I call the conjunction of these claims the Instrumentalist’s Conjunction. The so-called “Swamping Problem” is meant to show that Instrumentalist’s Conjunction is inconsistent. Crudely put, the problem is that if knowledge only has surplus value to the value of true belief, and a belief is true because (...) known, then knowledge cannot be of any more value than true belief. Given the inconsistency, most philosopher reject the claim the surplus value of knowledge is instrumental to the value of true belief. This paper argues that the Swamping Problem is illusory. Once we clean up the problem and pay attention to the distinction between token/type properties, we can see that Instrumentalist’s Conjunction is perfectly coherent. (shrink)

We discuss two objections that foundationalists have raised against infinite chains of probabilistic justification. We demonstrate that neither of the objections can be maintained.

From 1929 onwards, C. I. Lewis defended the foundationalist claim that judgements of the form 'x is probable' only make sense if one assumes there to be a ground y that is certain (where x and y may be beliefs, propositions, or events). Without this assumption, Lewis argues, the probability of x could not be anything other than zero. Hans Reichenbach repeatedly contested Lewis's idea, calling it "a remnant of rationalism". The last move in this debate was a challenge by (...) Lewis, defying Reichenbach to produce a regress of probability values that yields a number other than zero. Reichenbach never took up the challenge, but we will meet it on his behalf, as it were. By presenting a series converging to a limit, we demonstrate that x can have a definite and computable probability, even if its justification consists of an infinite number of steps. Next we show the invalidity of a recent riposte of foundationalists that this limit of the series can be the ground of justification. Finally we discuss the question where justification can come from if not from a ground. (shrink)

For decades, philosophers have displayed an interest in what it is to have an epistemically justified belief. Recently, we also find among philosophers a renewed interest in the so-called ethics of belief: what is it to believe responsibly and when is one’s belief blameworthy? This paper explores how epistemically justified belief and responsible belief are related to each other. On the so-called ‘deontological conception of epistemic justification’, they are identical: to believe epistemically responsibly is to believe epistemically justifiedly. I argue (...) that William Alston’s criticism of a deontological conception of epistemic justification in terms of our influence on our beliefs is unconvincing. Moreover, such a conception meets three criteria that one might put forward in order for an account of epistemic justification to be plausible: it shows a concern with the Jamesian goal of having true rather than false beliefs, it is relevantly similar to accounts of justification in non-doxastic realms, such as action, and there is good reason to think that, if spelled out in sufficient detail, it may well provide a necessary condition for knowledge. I conclude that the deontological conception of epistemic justification is stronger than is often thought: it is worth exploring whether epistemically justified belief is epistemically responsible belief.

Whether responsibility for actions and omissions requires the ability to do otherwise is an important issue in contemporary philosophy. However, a closely related but distinct issue, namely whether doxastic responsibility requires the ability to believe otherwise, has been largely neglected. This paper fills this remarkable lacuna by providing a defence of the thesis that doxastic responsibility entails the ability to believe otherwise. On the one hand, it is argued that the fact that unavoidability is normally an excuse counts in favour (...) of this thesis. On the other hand, three objections against this thesis are discussed and criticized. First, one might think that what suffices for doxastic responsibility is control over or influence on certain desirable or undesirable properties of beliefs. It is argued that this objection misrepresents the issue under consideration. Second, it may be objected that the thesis is contradicted by our intuitions in doxastic analogues of Frankfurt-style scenarios. It is argued that distinguishing between belief-universals and belief-particulars helps to see why this argument fails. Third and finally, one might draw an analogy with the asymmetry thesis in ethics by arguing that even if blameworthy belief requires the ability to believe otherwise, praiseworthy belief does not. It is argued that the main arguments in favour of this presumed asymmetry are wanting, partly because they fail to distinguish between two different kinds of praiseworthiness. Finally, the author sketches three implications of the thesis that doxastic responsibility entails the ability to believe otherwise: counterfactual construals of responsible belief might be tenable, the deontological conception of epistemic justification needs revision on an important point, and there might be an important asymmetry between beliefs on the one hand and actions and many non-doxastic consequences on the other.

The main stream of legal theory tends to incorporate unwritten principles into the law. Weighing of principles plays a great role in legal argumentation, inter alia in statutory interpretation. A weighing and balancing of principles and other prima facie reasons is a jump. The inference is not conclusive.To deal with defeasibility and weighing, a jurist needs both the belief-revision logic and the nonmonotonic logic. The systems of nonmonotonic logic included in the present volume provide logical tools enabling one to speak (...) precisely about various kinds of rules about rules, dealing with such things as applicability of rules, what is assumed by rules, priority between rules and the burden of proof. Nonmonotonic logic is an example of an extension of the domain of logic. But the more far-reaching the extension is, the greater problems it meets. It seems impossible to make logical reconstruction of the totality of legal argumentation. (shrink)

It is just over fifty years since the publication of Quine’s ‘Two Dogmas of Empiricism’. That paper expresses a broad vision of the system of relations between meaning, experience, and the rational formation of belief. The deepest challenges the paper poses come not from the detailed argument of its first four sections – formidable though that is – but from the visionary material in its last two sections.1 It is this visionary material that is likely to force the reader to (...) revise, to deepen, or to rethink her position on fundamental issues about the relations between meaning, experience, rationality, and, above all, the a priori. Does what is right in Quine’s argument exclude any rationalist view of these relations? How should a rationalist view be formulated? Those are the questions I will be addressing. I start with the critical part of this task, a consideration of the strengths and weaknesses of Quine’s vision. Drawing on the constraints emerging from that critical discussion, I will then turn to the positive task of articulating and defending a rival conception. The rival conception can be described as a Generalized Rationalism. (shrink)

Reasons rationalize beliefs. Reasons, when all goes well, turn true beliefs into knowledge. I am interested in the relationship between these aspects of reasons. Without a proper understanding of their relationship, the theory of knowledge will be less illuminating than it ought to be. I hope to show that previous accounts have failed to account for this relationship. This has resulted in a tendency to focus on justification rather than knowledge. It has also resulted in many becoming skeptical about the (...) prospects for an analysis of knowledge. The skepticism is misplaced and the tendency can be fixed without sacrificing any insights. The solution is to see how good reasons (in a sense to be articulated) are apparent (in a sense to be articulated) to the knowing subject. Once this claim is unpacked, we see that it is an illuminating analysis of knowledge in terms of distinct but intimately related aspects of epistemic assessment. It helps us see the value of knowledge (over and above true belief) and it affords us a unified, “reasons-first” metaepistemology. The resulting picture is neither a familiar kind of internalism or externalism. (shrink)

What is the relation between coherence and truth? This paper rejects numerous answers to this question, including the following: truth is coherence; coherence is irrelevant to truth; coherence always leads to truth; coherence leads to probability, which leads to truth. I will argue that coherence of the right kind leads to at least approximate truth. The right kind is explanatory coherence, where explanation consists in describing mechanisms. We can judge that a scientific theory is progressively approximating the truth if it (...) is increasing its explanatory coherence in two key respects: broadening by explaining more phenomena and deepening by investigating layers of mechanisms. I sketch an explanation of why deepening is a good epistemic strategy and discuss the prospect of deepening knowledge in the social sciences and everyday life. (shrink)

Putnam (1975) infers from the success of a scientific theory to its approximate truth and the reference of its key term. Laudan (1981) objects that some past theories were successful, and yet their key terms did not refer, so they were not even approximately true. Kitcher (1993) replies that the past theories are approximately true because their working posits are true, although their idle posits are false. In contrast, I argue that successful theories which cohere with each other are approximately (...) true, and that their key terms refer. My position is immune to Laudan’s counterexamples to Putnam’s inference and yields a solution to a problem with Kitcher’s position. (shrink)

In the tradition of substructural logics, it has been claimed for a long time that conjunction and inclusive disjunction are ambiguous:we should, in fact, distinguish between ‘lattice’ connectives (also called additive or extensional) and ‘group’ connectives (also called multiplicative or intensional). We argue that an analogous ambiguity affects the quantifiers. Moreover, we show how such a perspective could yield solutions for two well-known logical puzzles: McGee’s counterexample to modus ponens and the lottery paradox.

To avoid the problem of regress, externalists have put forward defeaters-based accounts of justification. The paper argues that existing proposals face two serious concerns: (i) They fail to accommodate related counterexamples such as Norman the clairvoyant, and, more worryingly, (ii) they fail to explain how one can be epistemically responsible in holding basic beliefs—i.e., they fail to explain how basic beliefs can avoid being arbitrary from the agent’s point of view. To solve both of these problems, a new, externalist, defeaters-based (...) account of justification is offered—viz., System Reliabilism. The core message of the view—and the way it deals with both (i) and (ii)—is the claim that the justificatory status of justified basic beliefs originates from being the undefeated outputs of a reliable, cognitively integrated system that is capable of defeating them. Simply put, to be candidates for being justified, basic beliefs must be epistemically responsible and to be so they must be undefeated while being defeasible. The paper also offers a detailed, naturalistic analysis of the notion of cognitive integration. This long-due, mechanistic account of cognitive integration is then used to argue that an additional advantage of System Reliabilism is its unique position to account for the as yet unexplained intuition that responsible beliefs are also likely to be true.

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.

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.

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.

The idea of ‘the given’ and its alleged problematic status as most famously articulated by Sellars continues to be at the center of heated controversies about foundationalism in epistemology, about ‘conceptualism’ and nonconceptual content in the philosophy of perception, and about the nature of the experiential given in phenomenology and in the cognitive sciences. I argue that the question of just what the myth of the given is supposed to be in the first place is more complex than has typically (...) been supposed in these debates, and that clarification of this prior question has surprising consequences. Foundationalism was only one of Sellars’s targets, and this not only in the familiar sense that the more fundamental issues at stake concern the very ‘objective purport’ or intentionality of our empirical thinking in general. When pushed further still, Sellars’s critique in fact hinged on his diagnoses of implicit framework-relative or ‘categorial’ metaphysical presuppositions he exposes in givenist views. Furthermore, the key to his critique accordingly turns out to rest on implicit assumptions concerning the in principle revisability or replaceability of any such presuppositions, whether ‘innate’ or acquired, and including Sellars’s own. Another key result is that widespread assumptions that Sellars’s famous critique is simply inapplicable or irrelevant to either ‘thin’ nonconceptualist views of the given, since they are ‘non-epistemic’; or alternatively, irrelevant to ‘thick’ conceptualist and phenomenological analyses –both turn out to be mistaken.

The notion of epistemic coherence is interpreted as involving not only consistency but also stability. The problem how to consolidate a belief system, i.e., revise it so that it becomes coherent, is studied axiomatically as well as in terms of set-theoretical constructions. Representation theorems are given for subtractive consolidation (where coherence is obtained by deleting beliefs) and additive consolidation (where coherence is obtained by adding beliefs).

Since our visual perception of physical things essentially involves our identifying objects by their colours, any theory of visual perception must contain some account of the colours of things. The central problem with colour has to do with relating our normal, everyday colour perceptions to what science, i.e. physics, teaches us about physical objects and their qualities. Although we perceive colours as categorical surface properties of things, colour perceptions are explained by introducing physical properties like reflectance profiles or dispositions to (...) cause certain experiences in normal human perceivers. Hence, it seems as if colours as they are experienced by us have no place in the physical world, because they are fundamentally different from the properties which we ascribe to physical objects in scientific accounts of colour perceptions. This special issue on perspectives on colour perception presents new suggestions to solve to this major problem. (shrink)

ABSTRACT This paper is on the justification of, the epistemic principle defended by M. Huemer in his Phenomenal Conservatism theory. Put in a straightforward way, we can ask: what reasons are there for thinking that is true, that is, for thinking that appearances justify beliefs? This question corresponds - to use L. BonJour’s vocabulary - to the demand for a “metajustification”. The pursuit of this metajustification can take different directions, depending on the general conception or nature of epistemic justification we (...) are working with and on who is supposed to satisfy the demand. Unfortunately, all of these directions seem to lead to a dead end. In other words, the apparently fair and even essential demand for a metajustification of cannot be met by the theory, at least in a satisfactory way.
