An encyclopedic article on epistemic supervenience in Blackwell companion to epistemology, 2 ed.

Persons think. Bodies, time-slices of persons, and brains might also think. They have the necessary neural equipment. Thus, there seems to be more than one thinker in your chair. Critics assert that this is too many thinkers and that we should reject ontologies that allow more than one thinker in your chair. I argue that cases of multiple thinkers are innocuous and that there is not too much thinking. Rather, the thinking shared between, for example, persons and their bodies is (...) exactly what we should expect at the intersection of part sharing and the supervenience of the mental on the physical. I end by responding to the overcrowding objection, the personhood objection, the personal-pronoun reference problem and the epistemic objection. (shrink)

ABSTRACTAccording to epistemic internalists, facts about justification supervene upon one's internal reasons for believing certain propositions. Epistemic externalists, on the other hand, deny this. More specifically, externalists think that the supervenience base of justification isn't exhausted by one's internal reasons for believing certain propositions. In the last decade, the internalism–externalism debate has made its mark on the epistemology of testimony. The proponent of internalism about the epistemology of testimony claims that a hearer's testimonial justification for believing that (...) p supervenes upon his internal reasons for thinking that the speaker's testimony that p is true. Recently, however, several objections have been raised against this view. In this paper, I present an argument providing intuitive support for internalism about the epistemology of testimony. Moreover, I also defend the argument against three recent objections offered by Stephen Wright in a couple of recent papers. The upshot of my discussion is that external conditions do make an epistemic difference when it comes to our testimonial beliefs, but that they cannot make any difference with respect to their justificatory status – i.e., they are justificationally irrelevant.

Simon Blackburn, in Truth A Guide for the Perplexed (Blackburn 2006), deploys the relation of thought with the facts and says, ‘We met the argument that theorizing involves an impossible activity of stepping outside our own skins and pretending to a ‘transcendental’ point of view, a standpoint from which we can survey the relationship between our thoughts and facts, without using the very forms of thought whose relation to the facts we are hoping to describe.’ (Blackburn, 2006, 109). My philosophical (...) reflections on this claim appreciate the view and turn towards the epistemic semblance in the metaphysical purview. A few challenges of the theory take up a side-effect of the ‘knowing procedures’ and its subsequent notion of the rigid concomitance of realism without a human face. My endeavor would be to slightly bypass the account of objective realism and debut into the sphere of the old-fashioned query, ‘what do we know about the conceptualized world where concepts steadily contaminate objects?’ We may appreciative beliefs and concepts, which are human creations, as these impart to the human-experienced world where concepts are the objective features of the subject’s conceptual scheme.

How a group G can know that p has been the subject of much investigation in social epistemology in recent years. This paper clarifies and defends a form of non-supervenient, non-summative group knowledge: G can know that p even if none of the members of G knows that p, and whether or not G knows that p does not locally supervene on the mental states of the members of G. Instead, we argue that what is central to G knowing that (...) p is whether G has an epistemic structure that is functioning appropriately in accord with the action-related purposes of the group, and this structure may include non-agential elements such as devices that retain or process information. We argue that recent objections to non-summative group knowledge given by Jennifer Lackey do not in fact succeed in undermining the view, but do help to clarify the nature of non-summative group knowledge. The main upshot of our response to Lackey’s objections is that groups put their knowledge into action in ways that often differ from how individuals do so, and social epistemologists should be careful to notice these differences, especially insofar as groups often structure themselves by employing various epistemically-relevant devices.

The aim of this paper is to discuss a seemingly straightforward argument against physicalism which, despite being implicit in much of the philosophical debate about consciousness, has not received the attention it deserves (compared to other, better-known “epistemic”, “modal”, and “conceivability” arguments). This is the argument from the non-supervenience of the first-personal (and indexical) facts on the third-personal (and non-indexical) ones. This non-supervenience, together with the assumption that the physical facts (as conventionally understood) are third-personal, entails that (...) some facts – namely, first-personal, phenomenal ones – do not supervene on the physical facts. Unlike other arguments against physicalism, the first-personal argument, if successful, refutes not only physicalism but also other third-personal metaphysical pictures, including standard versions of dualism.

Derk Pereboom has recently elaborated a formulation of non-reductive physicalism in which supervenience does not play the central role and realization plays no role at all; he calls his formulation “robust non-reductive physicalism”. This paper argues that for several reasons robust non-reductive physicalism is inadequate as a formulation of physicalism: it can only rule out fundamental laws of physical-to-mental emergence by stipulating that there are no such laws; it fails to entail the supervenience of the mental on the (...) physical; it appeals to two relations that are physicalistically unacceptable; and it rules out certain epistemically possible ways that the world might turn out to be according to current physics. This paper further argues that the difficulties faced by Pereboom’s robust non-reductive physicalism can all be avoided if physicalism is instead formulated by appeal to a carefully-defined relation of realization.

This chapter develops a style of argument that realists can use to defend the methodological propriety of appealing to a given range of intuitions. Unbunking arguments are an epistemically positive analogue of debunking arguments, and they revolve around the claim that the processes dominantly responsible for beliefs about a given domain are reliable. However, processes cannot always be assessed for accuracy with respect to the relevant domain, so this chapter also develops the cross-domain strategy, which involves arguing that processes known (...) to be reliable in one domain are similarly reliable with respect to a different domain. The chapter ends by unbunking our metaphysical intuitions about mutual supervenience by way of a cross-domain strategy that draws on cognitive scientific research into our ability to track correlations.

In this paper we motivate the ‘principles of trust’, chance-credence principles that are strictly stronger than the New Principle yet strictly weaker than the Principal Principle, and argue, by proving some limitative results, that the principles of trust conflict with Humean Supervenience.

In a lot of domains in metaphysics the tacit assumption has been that whichever metaphysical principles turn out to be true, these will be necessarily true. Let us call necessitarianism about some domain the thesis that the right metaphysics of that domain is necessary. Necessitarianism has flourished. In the philosophy of maths we find it held that if mathematical objects exist, then they do of necessity. Mathematical Platonists affirm the necessary existence of mathematical objects (see for instance Hale and Wright (...) 1992 and 1994; Wright 1983 and 1988; Schiffer 1996; Resnik 1997; Shapiro 1997 and Zalta 1988) while mathematical nominalists, usually in the form of fictionalists, hold that necessarily such objects fail to exist (see for instance Balaguer 1996 and 1998; Rosen 2001 and Yablo 2005). In metaphysics more generally, until recently it was more or less assumed that whatever the right account of composition—the account of under what conditions some xs compose a y—that account will be necessarily true (for a discussion of theories of composition see Simons 1987 and van Inwagen 1987 and 1990; the modal status of the composition relation is explicitly addressed in Schaffer 2007; Parsons 2006 and Cameron 2007). Similarly, it has generally been assumed that whatever the right account is of the nature of properties, whether they be universals, tropes, or whether nominalism is true, that account will be necessarily true (though see Rosen 2006 for a recent suggestion to the contrary). In considering theories of persistence it has been widely held that whether objects endure or perdure through time is a matter of necessity (Sider 2001; though see Lewis 1999 p227 who defends contingent perdurantism). And with respect to theories of time it is frequently held that whichever of the A- or B-theory is true is necessarily true. A-theorists often argue that there is time in a world only if the A-theory is true at that world (see for instance McTaggart 1903; Markosian 2004; Bigelow 1996; Craig 2001) while B-theorists often argue that the A-theory is internally inconsistent (Smart 1987; Mellor 1998; Savitt 2000 and Le Poidevin 1991). Once again, we find a few recent contingentist dissenters. Bourne (2006) suggests that it is a contingent feature of time that it is tensed, and thus that the A-theory is contingently true. Worlds in which there exist only B-theoretic properties are worlds with time, it is just that time in those worlds time is radically different to the way it is actually. Other defenders of the B-theory, though not expressly contingentists, do offer arguments against versions of the A-theory that try to show that such A-theories theories are inconsistent with the actual laws of nature (see for instance Saunders 2002 and Callender 2000); these arguments, at least, leave room for the possibility that the A-theories in question are contingently false (at least on the assumption that the laws of nature are themselves contingent, an assumption that not everyone accepts). Despite some notable exceptions, necessitarianism has flourished in many, if not most, domains in metaphysics. One such exception is Lewis’ famous defence of Humean supervenience as a contingent claim about our world. Lewis does not argue that necessarily, the supervenience base for all matters of fact in a world is nothing but a vast mosaic of local matters of particular fact. Rather, he thinks that we have reason to think that our world is one in which Humean supervenience holds (see Lewis 1986 p9-10 and 1994). Another exception to the necessitarian orthodoxy is to be found in the lively debate about the modal status of the laws of nature. Here, if anything, contingentism has been the dominating force, with it generally being held that there are possible worlds in which different laws of nature hold (this view is defended by, among others, Lewis 1986 and 2010; Schaffer 2005 and Sidelle 2002). Necessitarian dissenters hold that the laws of nature are necessary, frequently because they think it is necessary that fundamental properties have the causal or nomic profiles they do (see for instance Shoemaker 1980 and 1988; Swoyer 1982; Bird 1995; Ellis and Lierse 1994). Nevertheless, when it comes to thinking about the nature of the laws themselves, the necessitarian presumption is back on firm footing. Though there is disagreement about whether the laws are generalisations that feature in the most virtuous true axiomatisation of all the particular matters of fact (often known as the Humean view of laws and defended by Ramsey 1978; Lewis 1986 and Beebee 2000) or whether laws are relations of necessity that hold between universals (a view defended by Armstrong 1983; Dretske 1977; Tooley 1977 and Carroll 1990) no one has seriously suggested that it might be a contingent matter which of these is the right account of laws. The necessitarian orthodoxy is not surprising since metaphysics is largely an a priori process. While a priori reasoning may be used to determine whether a proposition is necessary or contingent, it is not well placed (in the absence of a posteriori evidence) to determine whether a contingent proposition is actually true or false. Since metaphysicians aim to tell us which principles are true in which worlds, on the face of it the discovery that metaphysical principles are contingent seems to make part of the task of metaphysics epistemically intractable. In what follows I consider two reasons one might end up embracing contingentism and whether this would lead one into epistemic difficulty. The following section considers a route to contingent metaphysical truths that proceeds via a combination of conceptual necessities and empirical discoveries. Section 3 considers whether there might be synthetic contingent metaphysical truths, and the final section raises the question of whether if there were such truths we would be well placed to come to know them.

Phenomenal concepts are the concepts that we deploy when – but arguably not only when – we introspectively examine, focus on, or take notice of the phenomenal character of our experiences. They refer to phenomenal properties (or qualities) and they do so in a subjective (first-personal) and direct (non-relational) manner. It is through the use of such concepts that the phenomenal character of our experiences is made salient to us. Discourse about the nature of phenomenal concepts plays an important role (...) in the philosophy of mind. For one, phenomenal concepts have been used to explain the epistemological relation that holds between a subject and her conscious mental states. Most prominently, however, discussions of phenomenal concepts figure in the on-going and multifaceted debate concerning the metaphysical status of consciousness. Even though some theorists have utilized phenomenal concepts in arguments purporting to show that consciousness is ontologically distinct from physical entities and processes, most accounts of phenomenal concepts are advanced having the opposite objective in mind: a proper articulation of the nature of phenomenal concepts, it is held, can defend the view that consciousness is physical against epistemic arguments to the contrary. The present entry focuses on the nature of phenomenal concepts as this is articulated and developed in attempts to defend the contention that conscious states are identical to (realized by, metaphysically necessitated by, or supervenient upon) physical states.

Various sexist and racist beliefs ascribe certain negative qualities to people of a given sex or race. Epistemic allies are people who think that in normal circumstances rationality requires the rejection of such sexist and racist beliefs upon learning of many counter-instances, i.e. members of these groups who lack the target negative quality. Accordingly, epistemic allies think that those who give up their sexist or racist beliefs in such circumstances are rationally responding to their evidence, while those who (...) do not are irrational in failing to respond to their evidence by giving up their belief. This is a common view among philosophers and non-philosophers. But epistemic allies face three problems. First, sexist and racist beliefs often involve generic propositions. These sorts of propositions are notoriously resilient in the face of counter-instances since the truth of generic propositions is typically compatible with the existence of many counter-instances. Second, background beliefs can enable one to explain away counter-instances to one’s beliefs. So even when counter-instances might otherwise constitute strong evidence against the truth of the generic, the ability to explain the counter-instances away with relevant background beliefs can make it rational to retain one’s belief in the generic despite the existence of many counter-instances. The final problem is that the kinds of judgements epistemic allies want to make about the irrationality of sexist and racist beliefs upon encountering many counter-instances is at odds with the judgements that we are inclined to make in seemingly parallel cases about the rationality of non-sexist and non-racist generic beliefs. Thus epistemic allies may end up having to give up on plausible normative supervenience principles. All together, these problems pose a significant prima facie challenge to epistemic allies. In what follows I explain how a Bayesian approach to the relation between evidence and belief can neatly untie these knots. The basic story is one of defeat: Bayesianism explains when one is required to become increasingly confident in chance propositions, and confidence in chance propositions can make belief in corresponding generics irrational.

Ramseyan humility is the thesis that we cannot know which properties realize the roles specified by the laws of completed physics. Lewis seems to offer a sceptical argument for this conclusion. Humean fundamental properties can be permuted as to their causal roles and distribution throughout spacetime, yielding alternative possible worlds with the same fundamental structure as actuality, but at which the totality of available evidence is the same. On the assumption that empirical knowledge requires evidence, we cannot know which of (...) these worlds is actual. However, Lewis also appeals to a range of familiar semantic principles when framing his argument, which leads some authors to suppose that he can also plausibly be interpreted as offering a purely semantic argument for humility in addition. In this paper I grant that these arguments are Lewisian, but argue that Lewis is also committed to a theory of mind that licenses a purely metaphysical argument for humility based on the idea that mental properties supervene on fundamental structure. Given that knowing which x is the F requires knowing that a is the F, the supposition that we could come to know which properties actually occupy the fundamental roles entails differences in mental properties between worlds with the same fundamental structure, violating supervenience. Humility follows right away, without any further epistemic or semantic principles. This argument is immune to almost every way of rebutting the sceptical and semantic arguments; conversely, almost every way of rebutting the metaphysical argument tells equally against the others.

Jesper Kallestrup has provided an insightful response to our paper, “Epistemic Structure in Non-Summative Social Knowledge”. Kallestrup identifies some important issues pertaining to our non-summative, non-supervenient account of group knowledge which we did not address in our original paper. Here, we develop our view further in light of Kallestrup’s helpful reply.

This expository paper presents a general framework for representing levels and inter-level relations. The framework is intended to capture both epistemic and ontological notions of levels and to clarify the sense in which levels of explanation might or might not be related to a levelled ontology. The framework also allows us to study and compare different kinds of inter-level relations, especially supervenience and reduction but also grounding and mereological constitution. This, in turn, enables us to explore questions such (...) as whether supervenience implies explanatory reducibility and whether there can be irreducible higher-level explanations or even “emergent” higher-level properties. The paper finally discusses some further philosophical applications: to the free-will debate, the determinism-indeterminism distinction, indexicality and consciousness, and the relationship between positive and normative facts.

Aesthetic properties figure prominently in our daily lives, our conversations and many actions we take. Yet theoretical disagreement prevails over their nature, their variety, their epistemic and metaphysical status. This overview highlights the heterogeneity of aesthetic properties and examines repercussions for explanation. Aesthetic properties belong to natural objects or scenes, to artworks in any medium, to artefacts and built environments across historical eras; and they draw a wide variety of responses such as our perceptions, emotions or imaginative thought. Historicism (...) about artworks carries over to at least some aesthetic properties that depend on facts of their broader historical context just as works do. One issue is whether aesthetic properties can be demarcated solely in terms of non-aesthetic properties. If not, explanations of aesthetic properties need to draw on other aesthetic notions such as aesthetic experience, attention, judgement or value. The paper examines several accounts of aesthetic value to show how they extend to aesthetic properties. The paper concludes with an overview of the current metaphysical debate between realists and non-realists about aesthetic properties. (shrink)

The subject of zombies is one of the most discussed and controversial topics of philosophy of mind. In this paper I will first examine the main argument of zombies, providing a summary of the current discussion. Then I will introduce a thought experiment, an epistemic window on a metaphysical scenario. By the thought experiment I will argue that zombies are logically impossible. Further I will discuss another recent epistemic window. Finally I will provide some other logical consideration to (...) prove that intentionality is not reducible to the cognitive functional aspects of the mind and that, moreover, the subjective recognition of semantic contents is necessary in order to consider as sensical the verbal behavior of a zombie.

We explore some possibilities for developing epistemic logic using truthmaker semantics. We identify three possible targets of analysis for the epistemic logician. We then list some candidate epistemic principles and review the arguments that render some controversial. We then present the classic Hintikkan approach to epistemic logic and note—as per the ‘problem of logical omniscience’—that it validates all of the aforementioned principles, controversial or otherwise. We then lay out a truthmaker framework in the style of Kit (...) Fine and present six different ways of extending this semantics with a conditional knowledge operator, drawing on notions of implication and content that are prominent in Fine’s work. We demonstrate that different logics are thereby generated, bearing on the aforementioned epistemic principles. Finally, we offer preliminary observations about the prospects for each logic.

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), (...) I propose a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

What if your peers tell you that you should disregard your perceptions? Worse, what if your peers tell you to disregard the testimony of your peers? How should we respond if we get evidence that seems to undermine our epistemic rules? Several philosophers have argued that some epistemic rules are indefeasible. I will argue that all epistemic rules are defeasible. The result is a kind of epistemic particularism, according to which there are no simple rules connecting (...) descriptive and normative facts. I will argue that this type of particularism is more plausible in epistemology than in ethics. The result is an unwieldy and possibly infinitely long epistemic rule — an Uber-rule. I will argue that the Uber-rule applies to all agents, but is still defeasible — one may get misleading evidence against it and rationally lower one’s credence in it. (shrink)

Examining previous discussions on how to construe the concepts of gender and race, we advocate what we call strategic conceptual engineering. This is the employment of a (possibly novel) concept for specific epistemic or social aims, concomitant with the openness to use a different concept (e.g., of race) for other purposes. We illustrate this approach by sketching three distinct concepts of gender and arguing that all of them are needed, as they answer to different social aims. The first concept (...) serves the aim of identifying and explaining gender-based discrimination. It is similar to Haslanger’s well-known account, except that rather than offering a definition of ‘woman’ we focus on ‘gender’ as one among several axes of discrimination. The second concept of gender is to assign legal rights and social recognitions, and thus is to be trans-inclusive. We argue that this cannot be achieved by previously suggested concepts that include substantial gender-related psychological features, such as awareness of social expectations. Instead, our concept counts someone as being of a certain gender solely based on the person’s self-identification with this gender. The third concept of gender serves the aim of personal empowerment by means of one’s gender identity. In this context, substantial psychological features and awareness of one’s social situation are involved. While previous accounts of concepts have focused on their role in determining extensions, we point to contexts where a concept’s role in explanation and moral reasoning can be more important.

Jennifer Nagel (2010) has recently proposed a fascinating account of the decreased tendency to attribute knowledge in conversational contexts in which unrealized possibilities of error have been mentioned. Her account appeals to epistemic egocentrism, or what is sometimes called the curse of knowledge, an egocentric bias to attribute our own mental states to other people (and sometimes our own future and past selves). Our aim in this paper is to investigate the empirical merits of Nagel’s hypothesis about the psychology (...) involved in knowledge attribution. (shrink)

In this paper, I argue that the “Ought Implies Can” (OIC) principle, as it is employed in epistemology, particularly in the literature on epistemic norms, is open to counterexamples. I present a counterexample to OIC and discuss several objections to it. If this counterexample works, then it shows that it is possible that S ought to believe that p, even though S cannot believe that p. If this is correct, then OIC, considered from an epistemic point of view, (...) is false, since it is supposed to hold for any S and any p. (shrink)

Recent work in cognitive science of religion (CSR) is beginning to converge on a very interesting thesis—that, given the ordinary features of human minds operating in typical human environments, we are naturally disposed to believe in the existence of gods, among other religious ideas (e.g., seeAtran [2002], Barrett [2004; 2012], Bering [2011], Boyer [2001], Guthrie [1993], McCauley [2011], Pyysiäinen [2004; 2009]). In this paper, we explore whether such a discovery ultimately helps or hurts the atheist position—whether, for example, it lends (...) credence to atheism by explaining away religious belief or whether it actually strengthens some already powerful arguments against atheism in the relevant philosophical literature.We argue that the recent discoveries of CSR hurt, not help, the atheist position—that CSR, if anything, should not give atheists epistemic assurance.

It has recently been argued that a person’s moral judgments (about both their own and others’ actions) are constrained by the nature and extent of their relevant ignorance and, thus, that such judgments are determined in the first instance by the person’s epistemic circumstances. It has been argued, in other words, that the epistemic is logically prior to other normative (e.g., ethical, prudential, pecuniary) considerations in human decision-making, that these other normative considerations figure in decision-making only after (logically (...) and temporally) relevant ignorance has constrained the decision-maker’s menu of options. If this is right, then a person’s moral judgments in some set of circumstances should vary with their knowledge and ignorance of these circumstances. In this study, we test the hypothesis of the logical priority of the epistemic. We describe two experiments in which subjects’ knowledge and ignorance of relevant consequences were manipulated. In the second experiment, we also compared the effect of ignorance on moral judgments with that of personal force, a factor previously shown to influence moral judgments. We found broad empirical support for the armchair arguments that epistemic considerations are logically prior to normative considerations. (shrink)

In this paper, I characterize visual epistemic representations as concrete two- or three-dimensional tools for conveying information about aspects of their target systems or phenomena of interest. I outline two features of successful visual epistemic representation: that the vehicle of representation contain sufficiently accurate information about the phenomenon of interest for the user’s purpose, and that it convey this information to the user in a manner that makes it readily available to her. I argue that actual epistemic (...) representation may involve tradeoffs between these and is successful to the extent that they are present. (shrink)

Introduces contextualism about knowledge ascriptions, and provides a brief summary of the contributions to the Routledge Handbook of Epistemic Contextualism.

Expressivists traditionally explain normative supervenience by saying it is a conceptual truth. I argue against this tradition in two steps. First, I show the modal claim that stands in need of explanation has been stated imprecisely. Classic arguments in metaethics for normative supervenience and those that rely on it as a premise presuppose a constraint on the supervenience base that is rarely (if ever) made explicit: the repeatability of the non-normative properties on which the normative supervenes. Non-normative (...) properties are repeatable when it is possible for numerically distinct individuals to share them. Second, I show if the modal truth that stands in need of explanation entails that there are individuals exactly alike in repeatable non-normative respects that cannot normatively differ, then standard expressivist accounts of normative supervenience as a conceptual truth are unsuccessful. Expressivist metasemantics for normative terms, together with constitutive facts about the non-cognitive attitudes essentially involved in normative thought, strongly suggest that repeatable supervenience could not be a conceptual truth. I argue, finally, that although repeatable supervenience bears the marks of a conceptual truth, expressivists should be content to treat it as an ordinary normative truth, and to explain it the same way they explain other normative truths.

Deference to experts is normal in many areas of inquiry, but suspicious in morality. This is puzzling if one thinks that morality is relevantly like those other areas of inquiry. We argue that this suspiciousness can be explained in terms of the suspiciousness of deferring to an epistemic peer. We then argue that this explanation is preferable to others in the literature, and explore some metaethical implications of this result.

Humean supervenience is the conjunction of three theses: Truth supervenes on being, Anti‐haecceitism, and Spatiotemporalism. The first clause is a core part of Lewis's metaphysics. The second clause is related to Lewis's counterpart theory. The third clause says there are no fundamental relations beyond the spatiotemporal, or fundamental properties of extended objects. Supervenience is classified into strong modal Humean supervenience, local modal Humean supervenience and familiar modal Humean supervenience which states that: for any two "worlds (...) like ours", if the spatiotemporal distribution of fundamental qualities is the same at each world, the contingent facts are also the same. The fact that quantum mechanics raises problems for Humean supervenience does not undercut the philosophical significance of Lewis's defense of Humean supervenience. Humean supervenience says that in a world like ours, the fundamental properties are local qualities: perfectly natural intrinsic properties of points, or of point‐sized occupants of points. (shrink)

Recent empirical work on non-philosophers’ intuitions about epistemic normativity reveals patterns that cannot be fully accounted for by direct epistemic consequentialism. On the basis of these results, one might picture participants as “epistemic deontologists.” We present the results of two new experiments that support a more nuanced picture. We examine intuitions about guesses and hypotheses, and about beliefs. Our results suggest a two-factor model of intuitions, wherein both consequentialist and non-consequentialist considerations affect participants’ judgments about epistemic (...) permissibility.

Political polarization is one of the most discussed challenges facing contemporary democracies and is often associated with a broader epistemic crisis. While inspiring a large literature in political science, polarization’s epistemic problems also have significance for normative democratic theory, and this study develops a new approach aimed at understanding them. In contrast to prominent accounts from political psychology—group polarization theory and cultural cognition theory—which argue that polarization leads individuals to form unreliable political beliefs, this study focuses on system-level (...) diversity. It argues that polarization’s epistemic harms are best located in its tendency to reduce the diversity of perspectives utilized in a democratic system and in how this weakens the system’s ability to identify and address problems of public concern. Understanding such harms is also argued to require a greater consideration of the political dynamics of polarization and issues of elite discourse, alongside political psychology. (shrink)

My interest lies in offering a phenomenological perspective on how noise is experienced, with particular attention to what may be common to different sorts of noise phenomena. As a counterpoint to the notion that noise is an empty or constructed notion, I argue for two desiderata of a phenomenological account of noise; accommodating a plurality of noise experiences, on the one hand, and clarifying their specific phenomenal character, on the other. I then pursue these desiderata by turning to an examination (...) of some contemporary views of perception that have implications for how the phenomenal character of perceptual noise in particular is to be understood; an epistemic misfire view and a sensory misfire view. After clarifying each and its appeal, I convey concerns about the one and the other. I propose a third alternative for further exploration - a perceptual disjoint view - and point to how it ought to explored. On the premise that there is something like a unity of consciousness or experience, I lay out the idea that there may then be many forms of 'disunities' of experience. From an analysis of the latter, I suggest, one may account for many different types of experiences of noise, though with a common ‘phenomenal’ thread running through them. (shrink)

ABSTRACT: Recently a bold and admirable interpretation of Chrysippus’ position on the Sorites has been presented, suggesting that Chrysippus offered a solution to the Sorites by (i) taking an epistemicist position1 which (ii) made allowances for higher-order vagueness. In this paper I argue (i) that Chrysippus did not take an epistemicist position, but − if any − a non-epistemic one which denies truth-values to some cases in a Sorites-series, and (ii) that it is uncertain whether and how he made (...) allowances for higher-order vagueness, but if he did, this was not grounded on an epistemicist position.

Reflectivists consider reflective reasoning crucial for good judgment and action. Anti-reflectivists deny that reflection delivers what reflectivists seek. Alas, the evidence is mixed. So, does reflection confer normative value or not? This paper argues for a middle way: reflection can confer normative value, but its ability to do this is bound by such factors as what we might call epistemic identity: an identity that involves particular beliefs—for example, religious and political identities. We may reflectively defend our identities’ beliefs rather (...) than reflect open-mindedly to adopt whatever beliefs cohere with the best arguments and evidence. This bounded reflectivism is explicated with an algorithmic model of reflection synthesized from philosophy and science that yields testable predictions, psychometric implications, and realistic metaphilosophical suggestions—for example, overcoming motivated reflection may require embracing epistemic identity rather than veiling it (à la Rawls 1971). So bounded reflectivism should be preferred to views offering anything less. (shrink)

This paper argues that regulatory agencies have a responsibility to further the public interest when they determine the conditions under which new technological products may be commercialized. As a case study, this paper analyzes the US 9th Circuit Court’s ruling on the efforts of the US Environmental Protection Agency to regulate an herbicide meant for use with seed that are genetically modified to be tolerant of the chemical. Using that case, it is argued that when regulatory agencies evaluate new technological (...) products, they have an obligation to draw on data, analyses, and evaluations from a variety of credible epistemic sources, and not rely solely or even primarily on the technology developer. Otherwise, they create conditions for their own domination and that of the polity by the technology developer. Moreover, in the interest of advancing the public interest, regulatory agencies must evaluate new technologies in a substantively and procedurally unbiased manner. (shrink)

A particularly influential thesis about epistemic axiology is veritism: that true belief is the only basic, or fully non-derivative, epistemic value. One recent argument against veritism claims that the naturalness or joint-carvingness of beliefs is also a basic epistemic value. The basic epistemic value of naturalness is held to explain intuitions that true, natural beliefs have greater epistemic value than similar but unnatural beliefs. I argue that epistemic significance, rather than naturalness, can best explain (...) any variations in the value of natural versus unnatural beliefs. Against claims that significance itself undermines veritism, I defend an account of significance that explains why the epistemic value of significance derives entirely from the value of truth. The account also shows how significance can be grounded in multiple features, while still deriving all its value from that of truth. As a result, the epistemic value of natural beliefs offers little reason to abandon veritism, in the absence of stronger arguments favoring the basic epistemic value of naturalness. (shrink)

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

In forming groups—corporations, teams, academic departments, juries—humans gain new ways of acting in the world. Jennifer Lackey argues that groups need to be held responsible for their actions, and therefore need to be subject to epistemic evaluation. To criticize receptive or reckless behavior on the part of a corporation, for example, we need some account of what it is for a group to believe something, and for a group belief to be justified. In Lackey’s account, group epistemic states (...) are a function of the states of individual operative members. After raising some difficulties for her formulation of this function, this article raises questions about Lackey’s operative-member account can apply to new types of group agent, with a particular focus on the epistemic status of algorithmic systems that harvest human data.

This paper explores the relationship between the questioning attitude of wondering and a class of attitudes I call 'epistemic desires'. Broadly, these are desires to improve one's epistemic position on some question. A common example is the attitude of wanting to know the answer to some question. I argue that one can have any kind of epistemic desire towards any question, Q, without necessarily wondering Q, but not conversely. That is, one cannot wonder Q without having at (...) least some epistemic desire directed towards Q. I defend this latter claim from apparent counterexamples due to Friedman (2013) and Drucker (2022), and finish with a proposal on which epistemic desires, particularly the desire for understanding, play an explanatory role in distinguishing wondering from other forms of question-directed thought.

The paper discusses approaches to Epistemic Contextualism that model the satisfaction of the predicate ‘know’ in a given context C in terms of the notion of belief/fact-matching throughout a contextually specified similarity sphere of worlds that is centred on actuality. The paper offers three counterexamples to approaches of this type and argues that they lead to insurmountable difficulties. I conclude that what contextualists (and Subject-Sensitive Invariantists) have traditionally called the ‘epistemic standards’ of a given context C cannot be (...) explicated in terms of a contextually specified similarity sphere that is centred on actuality. The mentioned accounts of epistemic relevance and thus the corresponding accounts of the context-sensitivity (or subject-sensitivity) of ‘knows’ are to be rejected. (shrink)

In this article, we advocate the use of “epistemic” ontologies, i.e., systems of categories representing our knowledge of the world, rather than the world directly. We first expose a metaphysical framework based on a dual mental and physical realism, which underpins the development of these epistemic ontologies. To this end, we refer to the theories of intentionality and representation established within the school of Franz Brentano at the turn of the 20th century and choose to rehabilitate the notion (...) of a ‘representation object’, as theorized by Kasimir Twardowski. We therefore propose that the categories of epistemic ontologies correspond to ‘general representation objects’. Secondly, we apply these proposals to the treatment of technical artefacts, material qualities of objects and events (notably as a continuation of our previous work on events). This leads us to sketch out a foundational epistemic ontology. (shrink)

The idea that appearances provide justifications for beliefs—the principle of phenomenal conservatism—is self-evidently true. In the case of cognitive penetration, however, it seems that certain irrational etiologies of a belief may influence the epistemic quality of that belief. Susanna Siegel argues that these etiologies lead to ‘epistemic downgrade.’ Instead of providing us with a decisive objection, cognitive penetration calls for us to clarify our epistemic framework by understanding the formative parts of appearances. In doing so, the two (...) different but inseparable ideas of sensation and intellection provide us with a basis of our appearances. These appearances, in turn, provide us with the objective evidence needed to test our judgements. Thus, the extra-sensory concepts of intellectual identification and the appearances they help form become an epistemic groundwork. (shrink)

We characterize four fruitful and underappreciated epistemic roles played by the concept of an individualized niche in contemporary biology, utilizing results of a qualitative empirical study conducted within an interdisciplinary biological research center. We argue that the individualized niche concept (1) shapes the research agenda of the center, (2) facilitates explaining core phenomena related to inter-individual differences, (3) helps with managing individual-level causal complexity, and (4) promotes integrating local knowledge from ecology, evolutionary biology, behavioral biology and other biological fields. (...) We thereby also challenge arguments that the niche concept is superfluous in ecology. (shrink)

This paper attempts to provide a remedy to a surprising lacuna in the current discussion in the epistemology of expertise, namely the lack of a theory accounting for the epistemic authority of collective agents. After introducing a service conception of epistemic authority based on Alvin Goldman’s account of a cognitive expert, I argue that this service conception is well suited to account for the epistemic authority of collective bodies on a non-summativist perspective, and I show in detail (...) how the defining requirements of an expert can apply to epistemic groups.

It is common belief that semantic properties supervene on non-semantic properties: no two possible worlds can be non-semantic duplicates and fail to be semantic duplicates. The view enjoys somewhat of an orthodoxy status in contemporary philosophy of language and metaphysics, and is often assumed without argument. Yet, work by Stephen Kearns and Ofra Magidor has claimed that it is vulnerable to a variant of the classical arguments against the supervenience of the phenomenal on the physical. This paper does three (...) things: it clarifies what semantic supervenience is about, it responds to the objections that have been leveled against it, and provides a new battery of arguments in its favor. I argue that the thesis of semantic supervenience is safe from classical anti-supervenience arguments, and show that its rejection generates unwelcome consequences. I conclude that there are substantial reasons to embrace the received wisdom: semantic properties supervene. (shrink)
