The idea that the concept ‘knowledge’ has a distinctive function or social role is increasingly influential within contemporary epistemology. Perhaps the best-known account of the function of ‘knowledge’ is that developed in Edward Craig’s Knowledge and the state of nature (1990, OUP), on which (roughly) ‘knowledge’ has the function of identifying good informants. Craig’s account of the function of ‘knowledge’ has been appealed to in support of a variety of views, and in this paper I’m concerned with the claim that (...) it supports a sort of epistemic contextualism, which is (roughly) the view that the semantic contents and truth-conditions of ‘knowledge’ ascriptions - instances of ‘S knows that p’- depend on and vary with the context of ascription (see, for instance, John Greco’s ‘What’s wrong with contextualism’, Philosophical Quarterly [2008]). Prima facie, this claim should strike us as surprising. A number of concepts and linguistic items (words, sentences) serve functions that have little or nothing to do with semantics. However, I argue that, on the best interpretation of talk of the function of a concept such as ‘knowledge’, the function of ‘knowledge’ is relevant to semantics. Along the way I also suggest how to improve on what I call the ‘usual argument’ that Craig’s account of the function of ‘knowledge’ supports epistemic contextualism. (shrink)

Many of us hold false beliefs about matters that are relevant to public policy such as climate change and the safety of vaccines. What can be done to rectify this situation? This question can be read in two ways. According to the descriptive reading, it concerns which methods will be effective in persuading people that their beliefs are false. According to the normative reading, it concerns which methods we are permitted to use in the service of persuading people. Some effective (...) methods—a programme of brainwashing, say—would not be permissible. In this paper I compare “methods of rational persuasion” with what you might call “marketing methods” such as how one frames the problem of climate change. My aim is to show that “marketing methods” are preferable to “methods of rational persuasion”. My argument has two parts. First, I argue that the evidence suggests that “marketing methods” are more effective in persuading people to change their minds. Second, I argue that “marketing methods” are an acceptable response to the normative question. (shrink)

Contextualism is the view that knowledge ascriptions – utterances of sentences containing the word “knows” - express different propositions in different contexts of utterance. But what features of context determine the propositions expressed by knowledge ascriptions? According to a version of contextualism I call conversational contextualism, the conversational dynamics or kinematics determine the propositions expressed by knowledge ascriptions. In this paper I argue that the most sophisticated version of conversational contextualism, which is the view defended by Michael Blome-Tillmann (2009; 2014), (...) faces serious problems. My (very) tentative conclusion will be that conversational contextualism should be abandoned because of these problems. (shrink)

Epistemic contextualists think that the truth-conditions of ‘knowledge’ ascriptions depend in part on the context in which they are uttered. But what features of context play a role in determining truth-conditions? The idea that the making salient of error possibilities is a central part of the story has often been attributed to contextualists, and a number of contextualists seem to endorse it (see Cohen (Philos Perspect, 13:57–89, 1999) and Hawthorne, (Knowledge and lotteries, Oxford University Press, Oxford, 2004)). In this paper (...) I argue that the focus on salience relations is a mistake. On the view I defend, the relevant features of context are facts about what error-possibilities and alternatives those in the context have a reason to consider, not facts about what error-possibilities and alternatives those in the context actually consider. As I will argue, this view has certain advantages over the standard view. (shrink)

In a recent article in this journal, Mona Simion argues that Sally Haslanger’s “engineering” approach to gender concepts such as ‘woman’ faces an epistemic objection. The primary function of all concepts—gender concepts included—is to represent the world, but Haslanger’s engineering account of ‘woman’ fails to adequately represent the world because, by her own admission, it doesn’t include all women in the extension of the concept ‘woman.’ I argue that this objection fails because the primary function of gender concepts—and social kind (...) concepts in general—is not (merely) to represent the world, but rather to shape it. I finish by considering the consequences for “conceptual engineering” in philosophy more generally. While Haslanger’s account may escape Simion’s objection, other appeals to conceptual engineering might not fair so well. (shrink)

In their ‘Metaethical contextualism defended’ (Ethics, 2010) Gunnar Björnsson & Stephen Finlay argue that metaethical contextualism - roughly, the view that 'ought' claims are semantically incomplete and require supplementation by certain parameters provided by the context in which they are uttered - can deal with two influential problems. The first concerns the connection between deliberation and advice (the 'practical integration problem'). The second concerns the way in which the expression ‘ought’ behaves in intra- and inter-contextual disagreement reports (the 'semantic assessment (...) problem'). I argue that, while Björnsson & Finlay can deal with the first problem, they can’t deal with the second. (shrink)

Recent work in psychology on ‘cultural cognition’ suggests that our cultural background drives our attitudes towards a range of politically contentious issues in science such as global warming. This work is part of a more general attempt to investigate the ways in which our wants, wishes and desires impact on our assessments of information, events and theories. Put crudely, the idea is that we conform our assessments of the evidence for and against scientific theories with clear political relevance to our (...) pre-existing political beliefs and convictions. In this paper I explore the epistemological consequences of cultural cognition. What does it mean for the rationality of our beliefs about issues such as global warming? I argue for an unsettling conclusion. Not only are those on the ‘political right’ who reject the scientific consensus on issues like global warming unjustified in doing so, some of those on the ‘political left’ who accept the consensus are also unjustified in doing so. I finish by addressing the practical implications of my conclusions. (shrink)

The slogan “Do Your Own Research” (DYOR) is often invoked by people who are distrustful, even downright sceptical, of recognized expert authorities. While this slogan may serve various rhetorical purposes, it also expresses an ethic of inquiry that valorises independent thinking and rejects uncritical deference to recognized experts. This paper is a qualified defence of this ethic of inquiry in one of the central contexts in which it might seem attractive. I use several case studies of patient activist groups to (...) argue that these groups often engage in valuable independent research that advances biomedical knowledge. In doing so they demonstrate the value of “lay expertise” and the epistemic as well as political necessity of not simply deferring to recognized experts. I also give some reasons why patient activist groups often produce valuable biomedical knowledge: they are examples of what I call “research collectives”. Research collectives are research communities that differ from the traditional research communities we find in universities and research institutes in that their members typically lack formal relevant scientific credentials and training. But they are similar in that they have internal structures—training procedures, norms of discussion, venues for holding discussions—that facilitate the production of knowledge. I finish by suggesting that future research into the differences and similarities between research collectives and traditional research communities is required. (shrink)

In this paper I develop a version of contextualism that I call interests contextualism. Interests contextualism is the view that the truth-conditions of knowledge ascribing and denying sentences are partly determined by the ascriber’s interests and purposes. It therefore stands in opposition to the usual view on which the truth-conditions are partly determined by the ascriber’s conversational context. I give an argument against one particular implementation of the usual view, differentiate interests contextualism from other prominent versions of contextualism and argue (...) that, unlike those versions, interests contextualism can mitigate against the epistemic descent objection put forward by Duncan Pritchard in his ‘Contextualism, Scepticism, and the Problem of Epistemic Descent’ (the objection is that, on the contextualist view, an ascriber of knowledge cannot, for some subject S and proposition p, properly ascribe knowledge that p to S if that ascriber has previously retracted an earlier ascription of knowledge that p to S).

This paper examines the ethical, epistemological, and political implications of persuasive AI technologies. Recent research suggests that AI is roughly as persuasive as humans in many contexts. Should this concern us? I argue that, while some worries about persuasive AI may be overblown, we should be worried for a mix of ethical, epistemological and political reasons. Most centrally, we should be worried because persuasive AI may lead to a small number of powerful actors dominating what I call the “marketplace of (...) arguments”—the set of arguments that are the materials we use to discuss important moral, political and societal issues.

Pragmatic encroachers argue that whether you know that p depends on a combination of pragmatic and epistemic factors. Most defenses of pragmatic encroachment focus on a particular pragmatic factor: how much is at stake for an individual. This raises a question: are there reasons for thinking that knowledge depends on other pragmatic factors that parallel the reasons for thinking that knowledge depends on the stakes? In this paper I argue that there are parallel reasons for thinking that knowledge depends on (...) social factors such as one’s social role or identity. I call this social encroachment. After defending social encroachment, I compare and contrast social encroachment with some key ideas in feminist epistemology. I argue that, while there are some important similarities, there are also some important differences. I finish by commenting on what I take the upshots of these differences to be. (shrink)

Marc Lange has recently raised three objections to the account of minimal model explanations offered by Robert Batterman and Collin Rice. In this article, I suggest that these objections are misguided. I suggest that the objections raised by Lange stem from a misunderstanding of the what it is that minimal model explanations seek to explain. This misunderstanding, I argue, consists in Lange’s seeing minimal model explanations as relating special types of models to particular target systems rather than seeing minimal model (...) explanations as looking to explain robust patterns of behavior that are exhibited by a variety of physically diverse systems.

Epistemic contextualists think that the extension of the expression ‘knows’ depends on and varies with the context of utterance. In the last 15 years or so this view has faced intense criticism. This paper focuses on two sorts of objections. The first are what I call the ‘linguistic objections’, which purport to show that the best available linguistic evidence suggests that ‘knows’ is not context-sensitive. The second is what I call the ‘disagreement problem’, which concerns the behaviour of ‘knows’ in (...) disagreement reports. These may not be the only objections to epistemic contextualism, but they are probably the most influential. I argue that the best current epistemic contextualist response to the linguistic objection is incomplete, and I show how it can be supplemented to deal with the full range of linguistic objections. I also develop a new solution to the disagreement problem. The upshot is that neither sort of objection gives us any reason to reject epistemic contextualism. This conclusion is, in a sense, negative—no new arguments for epistemic contextualism are advanced—but it’s a vital step towards rehabilitating the view. (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)

Skeptical invariantism isn’t a popular view about the semantics of knowledge attributions. But what, exactly, is wrong with it? The basic problem is that it seems to run foul of the fact that we know quite a lot of things. I agree that it is a key desideratum for an account of knowledge that it accommodate the fact that we know a lot of things. But what sorts of things should a plausible theory of knowledge say that we know? In (...) this paper I sketch an answer to this question and then apply it to skeptical invariantism. I start by distinguishing between a “radical” skeptical invariantist position (on which the standards for knowing are so high that we rarely if ever satisfy them) and a more “moderate” skeptical invariantist position (on which the standards are very hard, but not impossible, to satisfy). I then argue that, while radical forms of skeptical invariantism are clearly not going to do a good job of satisfying the key desideratum, more moderate forms can do quite well with respect to it. In particular, I argue the version of moderate skeptical invariantism defended by Davide Fassio can plausibly satisfy it. (shrink)

The target of this paper is the ‘simple’ knowledge account of assertion, according to which assertion is constituted by a single epistemic rule of the form ‘One must: assert p only if one knows p’. My aim is to argue that those who are attracted to a knowledge account of assertion should prefer what I call the ‘complex’ knowledge account, according to which assertion is constituted by a system of rules all of which are, taken together, constitutive of assertion. One (...) of those rules—which, following John Searle, I call the ‘preparatory condition’—is of the form ‘One must: assert p only if one knows p.’ All else being equal, simple accounts are preferable to complex accounts. I argue in this paper that all else isn't equal. While the simple knowledge account provides an elegant explanation of certain data, it is hard to see how to integrate the simple knowledge account into a more general theory of illocutionary acts. Because the complex knowledge account avoids this objection whil.. (shrink)

In her paper “Democracy, Public Policy, and Lay Assessments of Scientific Testimony” Elizabeth Anderson (2011) identifies a tension between the requirements of responsible public policy making and democratic legitimacy. The tension, put briefly, is that responsible public policy making should be based on the best available scientific research, but for it to be democratically legitimate there must also be broad public acceptance of whatever policies are put in place. In this chapter I discuss this tension, with a strong focus on (...) the issue of climate change. My aims are twofold. First, I argue that the tension is harder to resolve than Anderson supposes because some ways of securing acceptance for science-based policies will themselves be democratically illegitimate. Second, I take a closer look at the role intellectual autonomy plays in the tension. Many think that what I call “science marketing” methods for securing broad(er) acceptance of scientific claims are illegitimate because they infringe on our intellectual autonomy. I argue that it is less clear that this is true than many suppose. This is because, put roughly, judicious use of targeted science marketing methods need not stop us from developing the ability to think about scientific issues for ourselves. In fact, they may even aide us in developing this ability. While this doesn’t quite resolve the tension identified by Anderson, it does some of the necessary groundwork for resolving it. (shrink)

Many have rejected contextualism about ?knows? because the view runs into trouble with intra- and inter-contextual disagreement reports. My aim in this paper is to show that this is a mistake. First, I outline four desiderata for a contextualist solution to the problem. Second, I argue that two extant solutions to the problem fail to satisfy the desiderata. Third, I develop an alternative solution which satisfies the four desiderata. The basic idea, put roughly, is that ?knowledge? ascriptions serve the function (...) of recommending good informants, and disagreement over ?knowledge? ascriptions is a matter of conflicting recommendations. The upshot is that intra- and inter-contextual disagreement reports provide little?if any?reason to reject contextualism. (shrink)

“Political epistemology” has recently emerged as an area of analytic epistemology. While it may not be an entirely new area, and its precise boundaries are up for negotiation, recent political events in the UK (e.g. Brexit) and the US (e.g. the election of Donald Trump) played a key role in its rise to prominence within contemporary analytic epistemology. Further, political epistemology is an inter-disciplinary field, drawing on relevant work in political science, political psychology, and science communication that is often equally (...) focused on the UK and US. Political epistemology is therefore parochial, though it is the kind of parochialism that is not always conscious of itself as parochial. In this talk I adopt a critical stance towards parochialism in political epistemology. But my aim is not just to point out the mistakes that can result from a parochial concern with political events in one’s own country. I suggest that we can view political epistemology as interested in certain fundamental problems and tensions, which political epistemologists may then seek to identify and address within the political context in which they are working.

In this paper I consider the prospects for pluralism about knowledge, that is, the view that there is a plurality of knowledge relations. After a brief overview of some views that entail a sort of pluralism about knowledge, I focus on a particular kind of knowledge pluralism I call standards pluralism. Put roughly, standards pluralism is the view that one never knows anything simpliciter. Rather, one knows by this-or-that epistemic standard. Because there is a plurality of epistemic standards, there is (...) a plurality of knowledge relations. In §1 I argue that one can construct an impressive case for standards pluralism. In §2 I clarify the relationship between standards pluralism, epistemic contextualism and epistemic relativism. In §3 I argue that standards pluralism faces a serious objection. The gist of the objection is that standards pluralism is incompatible with plausible claims about the normative role of knowledge. In §4 I finish by sketching the form that a standards pluralist response to this objection might take. (shrink)

The electronic and muonic hydrogen energy levels are calculated very accurately [1] in Quantum Electrodynamics (QED) by coupling the Dirac Equation four vector (c ,mc2) current covariantly with the external electromagnetic (EM) field four vector in QED’s Interactive Representation (IR). The c -Non Exclusion Principle(c -NEP) states that, if one accepts c as the electron/muon velocity operator because of the very accurate hydrogen energy levels calculated, the one must also accept the resulting electron/muon internal spatial and time coordinate operators (ISaTCO) (...) derived directly from c without any assumptions. This paper does not change any of the accurate QED calculations of hydrogen’s energy levels, given the simplistic model of the proton used in these calculations [1]. The Proton Radius Puzzle [2, 3] may indicate that new physics is necessary beyond the Standard Model (SM), and this paper describes the bizarre, and very different, situation when the electron and muon are located “inside” the spatially extended proton with their Centers of Charge (CoCs) orbiting the proton at the speed of light in S energy states. The electron/muon center of charge (CoC) is a structureless point that vibrates rapidly in its inseparable, non-random vacuum whose geometry and time structure are defined by the electron/muon ISaTCO discrete geometry. The electron/muon self mass becomes finite in a natural way due to the ISaTCOs cutting off high virtual photon energies in the photon propagator. The Dirac-Maxwell-Wilson (DMW) Equations are derived from the ISaTCO for the EM fields of an electron/muon, and the electron/muon “look” like point particles in far field scattering experiments in the same way the electric field from a sphere with evenly distributed charge “e” “looks” like a point with the same charge in the far field (Gauss Law). The electron’s/muon’s three fluctuating CoC internal spatial coordinate operators have eight possible eigenvalues [4, 5, 6] that fall on a spherical shell centered on the electron’s CoM with radius in the rest frame. The electron/muon internal time operator is discrete, describes the rapid virtual electron/positron pair production and annihilation. The ISaTCO together create a current that produce spin and magnetic moment operators, and the electron and muon no longer have “intrinsic” properties since the ISaTCO kinematics define spin and magnetic moment properties.

Frege claims that the laws of logic are characterized by their “generality,” but it is hard to see how this could identify a special feature of those laws. I argue that we must understand this talk of generality in normative terms, but that what Frege says provides a normative demarcation of the logical laws only once we connect it with his thinking about truth and science. He means to be identifying the laws of logic as those that appear in every (...) one of the scientific systems whose construction is the ultimate aim of science, and in which all truths have a place. Though an account of logic in terms of scientific systems might seem hopelessly antiquated, I argue that it is not: a basically Fregean account of the nature of logic still looks quite promising.

This paper focuses on Martin Montminy’s recent attempt to show that assertion and practical reasoning are necessarily governed by the same epistemic norm (“Why assertion and practical reasoning must be governed by the same epistemic norm”, Pacific Philosophical Quarterly [2013]). I show that the attempt fails. I finish by considering the upshot for the recent debate concerning the connection between the epistemic norms of assertion and practical reasoning.

‘Mapping accounts’ of applied mathematics hold that the application of mathematics in physical science is best understood in terms of ‘mappings’ between mathematical structures and physical structures. In this paper, I suggest that mapping accounts rely on the assumption that the mathematics relevant to any application of mathematics in empirical science can be captured in an appropriate mathematical structure. If we are interested in assessing the plausibility of mapping accounts, we must ask ourselves: how plausible is this assumption as a (...) working hypothesis about applied mathematics? In order to do so, we examine the role played by mathematics in the multiscalar modelling of sea ice melting behaviour and examine whether we can indeed capture the mathematics involved in the kind of mathematical structure employed by the mapping account. Along the way, we note that the cases of applied mathematics that appear in discussions of mapping accounts almost exclusively involve the employment of a single clearly circumscribed mathematical field or domain. While the core assumption of mapping accounts may appear plausible in such situations, we ultimately suggest that the mapping account is not able to handle the important added complexities involved in our sea ice case study. In particular, the notion of mathematical structure around which such accounts are framed does not seem to be able to capture the way in which some applications of mathematics require that very different pieces of mathematics be related to one another on the basis of both mathematical and empirical information.

Dirt is evoked to signify many important facets of mountain bike culture including its emergence, history and everyday forms of practice and affect. These significations are also drawn upon to frame the sport's (sub)cultural and counter-ideological affiliations. In this article we examine how both the practice of mountain biking and, specifically, mountain bike trail building, raises questions over the object and latent function of dirt, hinting at the way that abjection can, under certain circumstances, be a source of intrigue and (...) pleasure. In doing so, we suggest a re-symbolization of our relationship with dirt via a consideration of the terrestrial. (shrink)

Commentators regularly attribute to Frege realist, idealist, and quietist responses to metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, the evidence offered on behalf of these attributions remains unconvincing. I argue that Frege deliberately avoids commitment to any of these positions, as part of a metaphysical separatist policy motivated by the fact that logic is epistemologically autonomous from metaphysics. Frege’s views and arguments prove relevant to current attempts to argue for epistemological autonomy, particularly that (...) of ethics. (shrink)

The philosophical investigation of perceptual illusions can generate fruitful insights in the study of subjective time consciousness. However, the way illusions are interpreted is often controversial. Recently, proponents of the so-called dynamic snapshot theory have appealed to the Waterfall Illusion, a kind of motion aftereffect, to support a particular view of temporal consciousness according to which experience is structured as a series of instantaneous snapshots with dynamic qualities. This dynamism is meant to account for familiar features of the phenomenology of (...) time, such as succession, continuity, and change. Previous theories have typically appealed to a subjective present occupying an interval of time; that is, a “specious present.” I argue, through analysis of motion aftereffect illusions and the rare condition of akinetopsia, i.e. motion-blindness, that the Waterfall Illusion fails to support the dynamic snapshot theory as intended. Furthermore, I suggest that future theories of subjective time should see temporal phenomenology as the result of non-localised processes closely tied to the mechanism underlying consciousness generally.

In the flash-lag effect a non-moving object is quickly flashed directly underneath a moving object, which leads us to perceive the non-moving object as “lagging” the moving object, even though the two objects actually occupy the same horizontal position at the time of the flash. In the example above, for instance, a red square moves across a screen. At the midpoint of the red square’s journey from one side to the other, a green square is quickly presented (flashed) just below. (...) Despite the fact that the two stimuli are presented at the same coordinates along the x axis, the stationary square is perceived as behind the moving square. The perceived lag of the flashed stationary object becomes greater when the speed of the moving object is increased and vice versa (Nijhawan 1994). (shrink)

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)

In the recent philosophy of language literature there is a debate over whether contextualist accounts of the semantics of various terms can accommodate intuitions of disagreement in certain cases involving those terms. Relativists such as John MacFarlane have claimed that this motivates adopting a form of relativist semantics for these terms because the relativist can account for the same data as contextualists but doesn’t face this problem of disagreement (MacFarlane 2005, 2007 and 2009). In this paper I focus on the (...) case of epistemic predicates and I argue that on a certain assumption about what is involved in assessing an utterance the epistemic contextualist can solve her problem of disagreement. This undercuts a motivation for epistemic relativism. (shrink)

Contextualists offer "high-low standards" practical cases to show that a variety of knowledge standards are in play in different ordinary contexts. These cases show nothing of the sort, I maintain. However Keith DeRose gives an ingenious argument that standards for knowledge do go up in high-stakes cases. According to the knowledge account of assertion (Kn), only knowledge warrants assertion. Kn combined with the context sensitivity of assertability yields contextualism about knowledge. But is Kn correct? I offer a rival account of (...) warranted assertion and argue that it beats Kn as a response to the "knowledge" version of Moore's Paradox. (shrink)

Darwin's and Freud's theories cohere in explaining human group conflict.

Empirical work on motivated reasoning suggests that our judgments are influenced to a surprising extent by our wants, desires and preferences (Kahan 2016; Lord, Ross, and Lepper 1979; Molden and Higgins 2012; Taber and Lodge 2006). How should we evaluate the epistemic status of beliefs formed through motivated reasoning? For example, are such beliefs epistemically justified? Are they candidates for knowledge? In liberal democracies, these questions are increasingly controversial as well as politically timely (Beebe et al. 2018; Lynch forthcoming, 2018; (...) Slothuus and de Vreese 2010). And yet, the epistemological significance of motivated reasoning has been almost entirely ignored by those working in mainstream epistemology. We aim to rectify this oversight. Using politically motivated reasoning as a case study, we show how motivated reasoning gives rise to three distinct kinds of skeptical challenges. We conclude by showing how the skeptical import of motivated reasoning has some important ramifications for how we should think about the demands of intellectual humility. (shrink)

Process reliabilism says that a belief is justified iff the belief-forming process that produced it is sufficiently reliable. But any token belief-forming process is an instance of a number of different belief-forming process types. The problem of specifying the relevant type is known as the ‘generality problem’ for process reliabilism. This paper proposes a broadly relativist solution to the generality problem. The thought is that the relevant belief-forming process type is relative to the context. While the basic idea behind the (...) solution is from Mark Heller (1995), the solution defended here departs from Heller on a crucial point. Because of this departure, my solution avoids a serious problem with Heller’s solution. (shrink)

This paper argues that there are no people. If identity isn't what matters in survival, psychological connectedness isn't what matters either. Further, fissioning cases do not support the claim that connectedness is what matters. I consider Peter Unger's view that what matters is a continuous physical realization of a core psychology. I conclude that if identity isn't what matters in survival, nothing matters. This conclusion is deployed to argue that there are no people. Objections to Eliminativism are considered, especially that (...) morality cannot survive the loss of persons. (shrink)

In this paper, we explore how a conversational theory of moral responsibility can provide illuminating resources for building a theory about the nature and norms of moral forgiveness.

Skepticism about the external world may very well be correct, so the question is in order: what theory of knowledge flows from skepticism itself? The skeptic can give a relatively simple and intuitive account of knowledge by identifying it with indubitable certainty. Our everyday ‘I know that p’ claims, which typically are part of practical projects, deploy the ideal of knowledge to make assertions closely related to, but weaker than, knowledge claims. The truth of such claims is consistent with skepticism; (...) various other vexing problems don’t arise. In addition, even if no claim about the world outside my mind can be more probable than its negation, the project of pure scientific research remains well motivated. (shrink)

In philosophical work on the ethics of conversational exchange, much has been written regarding the speaker side—i.e., on the rights and duties we have as speakers. This paper explores the relatively neglected topic of the duties pertaining to listeners’ side of the exchange. Following W.K. Clifford, we argue that it’s fruitful to think of our epistemic resources as common property. Furthermore, listeners have a key role in maintaining and improving these resources, perhaps a more important role than speakers. We develop (...) this idea by drawing from Hugo Mercier and Dan Sperber’s “interactionist” picture of reason, which suggests that reasoning is essentially dialogical and relies on the epistemic vigilance of listeners. The paper defends an imperfect, prima facie duty to listen, one that is sufficiently strong to place substantial demands on individuals, but not so overly demanding as to be implausible. (shrink)

The Genetic Algorithm (GA) and Simulated Annealing (SA), two techniques for global optimization, were applied to a reduced (simplified) form of the phase problem (RPP) in computational crystallography. Results were compared with those of "enhanced pair flipping" (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold (...) promise for phase problem applications. The RPP is, furthermore, an excellent test problem for such global optimization methods. (shrink)

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant of distributed cognition designed to scale up and (...) down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

This paper is about two topics: metaepistemological absolutism and the epistemic principles governing perceptual warrant. Our aim is to highlight—by taking the debate between dogmatists and conservativists about perceptual warrant as a case study—a surprising and hitherto unnoticed problem with metaepistemological absolutism, at least as it has been influentially defended by Paul Boghossian as the principal metaepistemological contrast point to relativism. What we find is that the metaepistemological commitments at play on both sides of this dogmatism/conservativism debate do not line (...) up with epistemic relativism nor do they line up with absolutism, at least as Boghossian articulates this position. What this case study reveals is the need in metaepistemological option space for the recognition of a weaker and less tendentious form of absolutism, what we call “environment relativism”. On this view, epistemic principles are knowable, objective, and they can serve as the basis of particular epistemic evaluations, but their validity is relative to the wider global environment in which they are applied.

In 1990 Edward Craig published a book called Knowledge and the State of Nature in which he introduced and defended a genealogical approach to epistemology. In recent years Craig’s book has attracted a lot of attention, and his distinctive approach has been put to a wide range of uses including anti-realist metaepistemology, contextualism, relativism, anti-luck virtue epistemology, epistemic injustice, value of knowledge, pragmatism and virtue epistemology. While the number of objections to Craig’s approach has accumulated, there has been no sustained (...) attempt to develop answers to these objections. In this paper we provide answers to seven important objections in the literature. (shrink)

This paper will argue that there are no people. Let me summarize the argument. In part II of what follows, I argue that if identity isn't what matters in survival, psychological connectedness isn't what matters either. Psychological connectedness, according to Derek Parfit, is the 'holding of particular direct psychological connections,' for example, when a belief, a desire, or some other psychological feature continues to be had ; psychological connectedness consists in two other relations—resemblance plus a cause that produces it. For (...) our purposes, to say of a relation that it is 'what matters in survival' is to say that it carries the burden of responsibility, remorse, and regret for past misdeeds; and that it is what makes rational the anticipation of, and the special hopes and fears we have about, our own future experiences. A consequence of II is that if identity isn't what matters in survival, either something other than psychological connectedness is what matters or nothing matters. (shrink)

In order to understand both consciousness and the Freudian unconscious we need to understand the notion of innerness that we apply to the mind. We can partly do so via the use of the theory of conceptual metaphor, and this casts light on a number of related topics.
