Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

The dogma that the propositional logic of metaphysical modality is S5 is rebutted. The author exposes fallacies in standard arguments supporting S5, arguing that propositional metaphysical modal logic is weaker even than both S4 and B, and is instead the minimal and weak metaphysical-modal logic T.

The Counterfactual Comparative Account of Harm says that an event is overall harmful for someone if and only if it makes her worse off than she otherwise would have been. I defend this account from two common objections.

Rather infamously, Kit Fine provided a series of counter‐examples which purport to show that attempts to understand essence in terms of metaphysical necessity are ‘fundamentally misguided’. Here, my aim is to put forward a new version of modalism that is, I argue, immune to Fine's counter‐examples. The core of this new modalist account is a sparseness restriction, such that an object's essential properties are those sparse properties it has in every world in which it exists. After first motivating this sparseness (...) restriction, I proceed to show how the resulting sparse modalism circumvents Fine's original counter‐examples. After dismissing a potential problem concerning the membership relation, I conclude that, as at least one form of modalism is viable, the project of understanding essence in terms of metaphysical necessity is not so fundamentally misguided after all.

In recent years there has been an explosion of philosophical work on blame. Much of this work has focused on explicating the nature of blame or on examining the norms that govern it, and the primary motivation for theorizing about blame seems to derive from blame’s tight connection to responsibility. However, very little philosophical attention has been given to praise and its attendant practices. In this paper, I identify three possible explanations for this lack of attention. My goal is to (...) show that each of these lines of thought is mistaken and to argue that praise is deserving of careful, independent analysis by philosophers interested in theorizing about responsibility.

Two theses figure centrally in work on the epistemology of disagreement: Equal Weight (‘EW’) and Uniqueness (‘U’). According to EW, you should give precisely as much weight to the attitude of a disagreeing epistemic peer as you give to your own attitude. U has it that, for any given proposition and total body of evidence, some doxastic attitude is the one the evidence makes rational (justifies) toward that proposition. Although EW has received considerable discussion, the case for U has not (...) been critically evaluated. Endorsing U, we argue, commits one to the highly controversial thesis that whatever fixes your rational attitudes can do so only by fixing what evidence you have. This commitment imposes a relatively demanding requirement on justified belief in U, one that we argue is not satisfied by what is currently the strongest available case for U, due to Roger White [2005]. Our challenge to U makes more trouble for its proponents than do the worries about U expressed by Gideon Rosen [2001] and Thomas Kelly [2010]. Moreover, if Kelly [2010] is correct in thinking that EW “carries with it a commitment to” U—a claim which we accept for reasons similar to Kelly’s but is beyond this paper’s scope (but see Ballantyne and Coffman [forthcoming])—then our challenge to U bears importantly on EW: to the extent that our challenge to U succeeds, EW also suffers.

In Hermathena, vol. xiv., pp. 338–359, Professor Charles Exon attempts to prove that the nom. and dat.-abl. pi. of deus were disyllabic in Plautus. The argument upon which he lays most stress is briefly this: Plautus uses iambic words shortened by the law of breves breviantes in the thesis of iambic and trochaic verse about twice as often as he does in the arsis, whereas the long monosyllable cor occurs in dialogue with equal frequency in both parts of the foot. (...) In this respect the nom. pl. of deus agrees with the shortened iambi, and should therefore, he thinks, be considered one of them. (shrink)

While it is tempting to suppose that an act has moral worth just when and because it is motivated by sufficient moral reasons, philosophers have, largely, come to doubt this analysis. Doubt is rooted in two claims. The first is that some facts can motivate a given act in multiple ways, not all of which are consistent with moral worth. The second is the orthodox view that normative reasons are facts. I defend the tempting analysis by proposing and defending a (...) heterodox account of both normative and motivating reasons that is inspired by Donald Davidson’s primary reasons. We should adopt the heterodox view, I argue, because it addresses an overlooked but fatal defect in the orthodox conception of reasons, of which challenges to the tempting analysis are a special case.

ABSTRACT: Most of what we believe comes to us from the word of others, but we do not always believe what we are told. We often reject thinkers' reports by attributing biases to them. We may call this debunking. In this essay, I consider how debunking might work and then examine whether, and how often, it can help to preserve rational belief in the face of disagreement.

There are certain uses of and and or that cannot be explained by their normal meanings as truth-functional connectives, even with sophisticated pragmatic resources. These include examples such as The cops show up, and a fight will break out (‘If the cops show up, a fight will break out’), and I have no friends, or I would throw a party (‘I have no friends. If I did have friends, I would throw a party.’). We argue that these uses are indeed (...) distinct from the more ordinary uses of and and or, but that they are nonetheless related in a principled way. To explain them we give an analysis of what we call the dynamic effects of connectives, which arise in all their uses. The special uses at issue are then argued to be instances where the connectives exhibit their dynamic effects without their truth-conditional meaning. (shrink)

There is general consensus that explainable artificial intelligence is valuable, but there is significant divergence when we try to articulate why, exactly, it is desirable. This question must be distinguished from two other kinds of questions asked in the XAI literature that are sometimes asked and addressed simultaneously. The first and most obvious is the ‘how’ question—some version of: ‘how do we develop technical strategies to achieve XAI?’ Another question is specifying what kind of explanation is worth having in the (...) first place. As difficult and important as the challenges are in answering these questions, they are distinct from a third question: why do we want XAI at all? There is vast literature on this question as well, but I wish to explore a different kind of answer. The most obvious way to answer this question is by describing a desirable outcome that would likely be achieved with the right kind of explanation, which would make the explanation valuable instrumentally. That is, XAI is desirable to attain some other value, such as fairness, trust, accountability, or governance. This family of arguments is obviously important, but I argue that explanations are also intrinsically valuable, because unexplainable systems can be dehumanizing. I argue that there are at least three independently valid versions of this kind of argument: an argument from participation, from knowledge, and from actualization. Each of these arguments that XAI is intrinsically valuable is independently compelling, in addition to the more obvious instrumental benefits of XAI. (shrink)

We offer an original argument for the existence of universal fictions—that is, fictions within which every possible proposition is true. Specifically, we detail a trio of such fictions, along with an easy-to-follow recipe for generating more. After exploring several consequences and dismissing some objections, we conclude that fiction, unlike reality, is unlimited when it comes to truth.

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

Recent work on the nature of luck widely endorses the thesis that an event is good or bad luck for an individual only if it is significant for that individual. In this paper, I explore this thesis, showing that it raises questions about interests, well-being, and the philosophical uses of luck. In Sect. 1, I examine several accounts of significance, due to Pritchard (2005), Coffman (2007), and Rescher (1995). Then in Sect. 2 I consider what some theorists want to ‘do’ (...) with luck, taking important examples from epistemology (explaining Gettier-style examples) and political philosophy (offering a rationale for the just distribution of resources in society), while suggesting implications for significance. Drawing together lessons from Sects. 1 and 2, I develop a new account of significance in Sect. 3 before concluding with reflections on the debate in Sect. 4. (shrink)

The past decade and a half has seen an absolute explosion of literature discussing the structure of reality. One particular focus here has been on the fundamental. However, while there has been extensive discussion, numerous fundamental questions about fundamentality have not been touched upon. In this chapter, I focus on one such lacuna about the modal strength of fundamentality. More specifically, I am interested in exploring the contingent fundamentality thesis - that is, the idea that the fundamentalia are only contingently (...) fundamental (or, in property-terms, that the property of being fundamental is not a (weakly) necessary property). And while I think this thesis is plausible – indeed, I show here that it lurks in the unexamined shadows/assumptions of some fairly prominent positions – as far as I can tell, nothing has been said either for or against it. Here, I hope to fix this by giving the thesis a proper airing. In this way, this chapter represents a first-pass at exploring not only the modal status of fundamentality, but also offers a starting point for examining broader issues about the relationship between fundamentality and modality.

Some epistemologists hold that exploration and elaboration of the nature of luck will allow us to better understand knowledge. I argue this is a mistake.

Some have attempted to explain why it appears that action based on deferential moral belief lacks moral worth by appealing to claims about an attitude that is difficult to acquire through testimony, which theorists have called “moral understanding”. I argue that this state is at least partly non-cognitive. I begin by employing case-driven judgments to undermine the assumption that I argue is responsible for the strangeness of deferential moral belief: the assumption that if an agent knows that some fact gives (...) them a moral reason to act in some way, then they’re in a position to act that way for the moral reason given by that fact. I then argue that cases from non-moral epistemology concerning properly-based belief give us independent reason to reject this assumption and conclude by sketching a Davidson-inspired account of normative reasons that explains why acting for moral reasons requires the right non-cognitive state, which is worth calling a kind of moral understanding.

Confirmation bias has been widely studied for its role in failures of reasoning. Individuals exhibiting confirmation bias fail to engage with information that contradicts their current beliefs, and, as a result, can fail to abandon inaccurate beliefs. But although most investigations of confirmation bias focus on individual learning, human knowledge is typically developed within a social structure. We use network models to show that moderate confirmation bias often improves group learning. However, a downside is that a stronger form of confirmation (...) bias can hurt the knowledge producing capacity of the community. (shrink)

In this paper, I consider a novel challenge to John Martin Fischer and Mark Ravizza’s reasons-responsiveness theory of moral responsibility. According to their view, agents possess the control necessary for moral responsibility if their actions proceed from a mechanism that is moderately reasons-responsive. I argue that their account of moderate reasons-responsiveness fails to provide necessary and sufficient conditions for moral responsibility since it cannot give an adequate account of the responsibility of individuals with autism spectrum disorder. Empirical evidence suggests that (...) autistic individuals demonstrate impairments in counterfactual thinking, and these impairments, I argue, are such that they cast doubt on Fischer and Ravizza’s construal of moderate reasons-responsiveness. I then argue that modifying the view in order to accommodate individuals with ASD forces them to defend a strong reasons-responsive account despite the fact that they explicitly deny that such an account can adequately characterize what it is to be morally responsible for one’s actions.

According to Westermarck’s widely accepted explanation of the incest taboo, cultural prohibitions on sibling sex are rooted in an evolved biological disposition to feel sexual aversion toward our childhood coresidents. Bernard Williams posed the “representation problem” for Westermarck’s theory: the content of the hypothesized instinct is different from the content of the incest taboo —thus the former cannot be causally responsible for the latter. Arthur Wolf posed the related “moralization problem”: the instinct concerns personal behavior whereas the prohibition concerns everyone. (...) This paper reviews possible ways of defending Westermarck’s theory from the representation and moralization problems, and concludes that the theory is untenable. A recent study purports to support Westermarck’s account by showing that unrelated children raised in the same peer groups on kibbutzim feel sexual aversion toward each other and morally oppose third-party intra-peer-group sex, but this study has been misinterpreted. I argue that the representation and moralization problems are general problems that could potentially undermine many popular evolutionary explanations of social/moral norms. The cultural evolution of morality is not tightly constrained by our biological endowment in the way some philosophers and evolutionary psychologists believe. (shrink)

In this paper, I present a challenge for Michael McKenna’s conversational theory of moral responsibility. On his view, to be a responsible agent is to be able to engage in a type of moral conversation. I argue that individuals with autism spectrum disorder present a considerable problem for the conversational theory because empirical evidence on the disorder seems to suggest that there are individuals in the world who meet all of the conditions for responsible agency that the theory lays out (...) but who are nevertheless not responsible agents. Attending to the moral psychology of such individuals will, I think, help shed light on an important gap in the conversational theory. (shrink)

A central claim of Deleuze's reading of Bergson is that Bergson's distinction between space as an extensive multiplicity and duration as an intensive multiplicity is inspired by the distinction between discrete and continuous manifolds found in Bernhard Riemann's 1854 thesis on the foundations of geometry. Yet there is no evidence from Bergson that Riemann influences his division, and the distinction between the discrete and continuous is hardly a Riemannian invention. Claiming Riemann's influence, however, allows Deleuze to argue that quantity, in (...) the form of ‘virtual number’, still pertains to continuous multiplicities. This not only supports Deleuze's attempt to redeem Bergson's argument against Einstein in Duration and Simultaneity, but also allows Deleuze to position Bergson against Hegelian dialectics. The use of Riemann is thereby an important element of the incorporation of Bergson into Deleuze's larger early project of developing an anti-Hegelian philosophy of difference. This article first reviews the role of discrete and continuous multiplicities or manifolds in Riemann's Habilitationsschrift, and how Riemann uses them to establish the foundations of an intrinsic geometry. It then outlines how Deleuze reinterprets Riemann's thesis to make it a credible resource for Deleuze's Bergsonism. Finally, it explores the limits of this move, and how Deleuze's later move away from Bergson turns on the rejection of an assumption of Riemann's thesis, that of ‘flatness in smallest parts’, which Deleuze challenges with the idea, taken from Riemann's contemporary, Richard Dedekind, of the irrational cut.

Discussions of political obligation and political authority have long focused on the idea that the commands of genuine authorities constitute content-independent reasons. Despite its centrality in these debates, the notion of content-independence is unclear and controversial, with some claiming that it is incoherent, useless, or increasingly irrelevant. I clarify content-independence by focusing on how reasons can depend on features of their source or container. I then solve the long-standing puzzle of whether the fact that laws can constitute content-independent reasons is (...) consistent with the fact that some laws must fail to bind due to their egregiously unjust content. Finally I defend my understanding of content-independence against challenges and show why it retains a place of special importance for questions about the law and political obligation. Content-independence highlights that it is some feature of the law or law-making process in general that is supposed to generate moral obligations for citizens, not the merits of particular laws.

Although Professor Schiffer and I have many times disagreed, I share his deep and abiding commitment to argument as a primary philosophical tool. Regretting any communication failure that has occurred, I endeavor here to make clearer my earlier reply in “Illogical Belief” to Schiffer’s alleged problem for my version of Millianism.1 I shall be skeletal, however; the interested reader is encouraged to turn to “Illogical Belief” for detail and elaboration. I have argued that to bear a propositional attitude de re (...) is to bear that attitude toward the corresponding singular proposition, no more and no less. If this is right, then according to Millianism every instance of the following modal schema is true. (shrink)

Paradoxes of nested modality, like Chisholm’s paradox, rely on S4 or something stronger as the propositional logic of metaphysical modality. Sarah-Jane Leslie’s objection to the resolution of Chisholm’s paradox by means of rejection of S4 modal logic is investigated. A modal notion of essence congenial to Leslie’s objection is clarified. An argument is presented in support of Leslie’s crucial but unsupported assertion that, on pain of inconsistency, an object’s essence is the same in every possible world. A fallacy in the (...) argument is exposed. Alternative interpretations of Leslie’s objection are provided and are found to involve equivocation between different notions of “essence.” A material artifact’s modal essence, as distinct from its quiddity essence, could have been different than it is.

This article presents and discusses one of the most prominent inferential strategies currently employed in cognitive neuropsychology, namely, reverse inference. Simply put, this is the practice of inferring, in the context of experimental tasks, the engagement of cognitive processes from locations or patterns of neural activation. This technique is notoriously controversial because, critics argue, it presupposes the problematic assumption that neural areas are functionally selective. We proceed as follows. We begin by introducing the basic structure of traditional “location-based” reverse inference (...) and discuss the influential lack of selectivity objection. Next, we rehearse various ways of responding to this challenge and provide some reasons for cautious optimism. The second part of the essay presents a more recent development: “pattern-decoding reverse inference”. This inferential strategy, we maintain, provides an even more convincing response to the lack of selectivity charge. Due to this and other methodological advantages, it is now a prominent component in the toolbox of cognitive neuropsychology. Finally, we conclude by drawing some implications for philosophy of science and philosophy of mind. (shrink)

Many philosophers think that an agent punishes a subject only if the agent aims to harm the subject. Bill Wringe has recently argued against this claim. I show that his arguments fail.

How is it that we can rationally assert that sport outcomes do not really matter, while also seeming to care about them to an absurd degree? This is the so-called puzzle of sport. The broadly Waltonian solution to the puzzle has it that we make-believe the outcomes matter. Recently, Stear has critiqued this Waltonian solution, raising a series of five objections. He has also leveraged these objections to motive his own contextualist solution to the puzzle. The aim of this paper (...) is to defend the Waltonian solution. The general upshot is that, contra Stear, a make-believe based solution to the puzzle is viable after all. (shrink)

While there is a great deal to agree with in the essay Expanded Terminal Sedation in End-of-Life Care there is, we think, a need to more fully appreciate the humanistic side of both palliative and end-of-life care.1 Not only does the underlying philosophy of palliative care arguably differ from that which guides curative medicine,2 dying patients are in a uniquely vulnerable position given our cultural disinclination towards open discussions of death and dying. In this brief response, we critically engage Gilbertson (...) et al ’s essay and seek to contextualise the perspective they put forward. According to Cassell, we should distinguish between pain and suffering.3 The former often gives rise to the latter, but suffering has other causes. This includes existential distress, indicating that, unlike pain, suffering is not simply physiological phenomena. Suffering involves the disintegration of the person, meaning that it can impact patient autonomy. Certainly, that a patient is suffering does not equate to a lack autonomy. Nevertheless, we should take care when making decisions in circumstance where the integrity of our embodied personhood is under threat, something that is clearly the case for those who are dying, particularly those who have refractory symptoms while doing so. Generally speaking, refractory symptoms are those which are intractable. They persist despite attempts at palliation. While this implies that such symptoms—and the suffering they cause—cannot be reversed this is not necessarily the case. Not only can the symptoms experienced by dying patients change …. (shrink)

I criticize an increasingly popular set of arguments for the justifiability of punishment. Some philosophers try to justify punishment by appealing to what Peter Strawson calls the reactive attitudes – emotions like resentment, indignation, remorse and guilt. These arguments fail. The view that these emotions commit us to punishment rests on unsophisticated views of punishment and of these emotions and their associated behaviors. I offer more sophisticated accounts of punishment, of these emotions and of their associated behaviors that are consistent (...) with Abolitionism, the view that punishment is unjustified. (shrink)

One of the most common excuses is ignorance. Ignorance does not always excuse, however, for sometimes ignorance is culpable. One of the most natural ways to think of the difference between exculpating and culpable ignorance is in terms of justification; that is, one’s ignorance is exculpating only if it is justified and one’s ignorance is culpable only if it not justified. Rosen :591–610, 2008) explores this idea by first offering a brief account of justification, and then two cases that he (...) claims are counter examples to the justification thesis. The aim of this paper is to defend the justification thesis against Rosen’s two cases. The argument will proceed in the following way. First, I clarify a few things about the nature of culpable ignorance generally and why the justification thesis is so intuitive. I then present Rosen’s purported counterexamples. Once this is done, I argue that Rosen misses an important view of justification in the epistemology literature that I call the pragmatic view. I present a general picture of the pragmatic view, and explain how it fits naturally with our practices of criticizing people’s beliefs, including claims of culpable ignorance. Finally, I address Rosen’s cases arguing that, if the pragmatic view is right, then Rosen’s cases are not counterexamples to the justification thesis. (shrink)

Philosophers have recently come to focus on explaining the phenomenon of ​bad beliefs,​ beliefs that are apparently true and well-evidenced but nevertheless objectionable. Despite this recent focus, a consensus is already forming around a particular explanation of these beliefs’ badness called ​moral encroachment​, according to which, roughly, the moral stakes engendered by bad beliefs make them particularly difficult to justify. This paper advances an alternative account not just of bad beliefs but of bad attitudes more generally according to which bad (...) beliefs’ badness originates not in a failure of sufficient evidence but in a failure to respond adequately to reasons. I motivate this alternative account through an analogy to recent discussions of moral worth centered on the well-known grocer case from Kant’s ​Groundwork​, and by showing that this analogy permits the proposed account to generalize to bad attitudes beyond belief. The paper concludes by contrasting the implications of moral encroachment and of the proposed account for bad attitudes’ blameworthiness. (shrink)

What can just about any philosophical person who agrees with many goals that are often considered feminist do in response to the problems of the world? Among many other things, they can do philosophy, online, on various social media platforms, to try to help steer the world in better directions, at least a little. -/- Now “doing philosophy” with these goals in mind can mean many different things to different people: there are many different ways to be engaged in “public (...) philosophy.” Here though I’ll briefly describe some what I have been doing for at least a few years, which could be described as a type of “philosophical fact-checking” that basically amounts to this: -/- when people and organizations make importantly problematic claims about philosophical and ethical issues that one has expertise in, provide responses and resources that correct that misinformation.
