YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

This chapter explores a case study in contemporary fanaticism. We adopt Katsafanas’s conceptualization of fanaticism to make possible an in-depth discussion of and evaluation of a diffuse but important social movement — the anglophone manosphere. According to Katsafanas, fanatics are fruitfully understood as members of a group that adopts sacred values which they hold unconditionally to preserve their own psychic unity, and who feel that those values are threatened by those who do not accept them. The manosphere includes several social (...) movements, including incels, men’s rights activists, and men-going-their-own-way. We show that many members of these groups are well-characterized by Katsafanas’s theory of fanaticism, and that they have forged their fanatical group identity using tools that philosophers have tended to associate with more benign social movements and the task of “conceptual engineering.” Indeed, we think that manosphere groups have in many cases been more successful than more palatable liberationist movements, and that this case study in the dark side of conceptual engineering may be both sobering and informative.

This paper presents five studies on the development and validation of a scale of intellectual humility. This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity. In particular, Open-mindedness (...) adds predictive power beyond the Big Six for an objective behavioral measure of intellectual humility, and Intellectual Modesty is uniquely related to Narcissism. We find that a similar factor structure emerges in Germanophone participants, giving initial evidence for the model’s cross-cultural generalizability. (shrink)

Some objects we value because they afford a felt connection with people, events, or places connected with their past. Visiting Canterbury cathedral, you encounter the place where, in 1170, Archbishop Thomas Becket was murdered by four knights of Henry II. Knowing that you are standing in the very place where Becket’s blood was spilled gives the past event a sense of tangible reality. One feels ‘in touch with’ the past; history seems to ‘come alive’. In this paper, I propose an (...) explanation for the phenomenology of such experiences in terms of an imaginative activity that represents what an object is historically connected with as part of the object in the present. One imagines of the site of Becket’s murder Becket being murdered. According to my account, objects that embody their histories are representations in Kendall Walton’s sense: they have the function of serving as props in games of make-believe. (shrink)

In this chapter, we address the roles that exemplars might play in a comprehensive response to epistemic injustice. Fricker defines epistemic injustices as harms people suffer specifically in their capacity as (potential) knowers. We focus on testimonial epistemic injustice, which occurs when someone’s assertoric speech acts are systematically met with either too little or too much credence by a biased audience. Fricker recommends a virtue­theoretic response: people who do not suffer from biases should try to maintain their disposition towards naive (...) testimonial justice, and those who find themselves already biased should cultivate corrective testimonial justice by systematically adjusting their credence in testimony up or down depending on whether they are hearing from someone whom they may be biased against or in favor of. We doubt that the prominent admiration­emulation model of exemplarism will be much use in this connection, so we propose two ways of learning from negative exemplars to better conduct one’s epistemic affairs. In the admiration­emulation model, both the identification of what a virtue is and the cultivation of virtues identified thusly proceed through the admiration of virtuous exemplars. We show that this model has serious flaws and argue for two alternatives: the envy­agonism model and the ambivalence­avoidance model. (shrink)

Many hold that aesthetic appreciation is sensitive to the authenticity or genuineness of an object. In a recent body of work, Carolyn Korsmeyer has defended the claim that genuineness itself is an aesthetic property. Korsmeyer’s aim is to explain our aesthetic appreciation of objects that afford a sense of being ‘in touch with the past’. In this paper, I argue that genuineness cannot explain our appreciation of these objects. There is no aesthetic experience of the genuine.

Beginning with the Untimely Meditations (1873) and continuing until his final writings of 1888-9, Nietzsche refers to humility (Demuth or a cognate) in fifty-two passages and to modesty (Bescheidenheit or a cognate) in one hundred and four passages, yet there are only four passages that refer to both terms. Moreover, perhaps surprisingly, he often speaks positively of modesty, especially in epistemic contexts. These curious facts might be expected to lead scholars to explore what Nietzsche thinks of humility and modesty, but (...) to date there have been no systematic analyses of Nietzsche’s reflections on these dispositions. In this chapter, I fill that gap in the literature using semantic network analysis and systematically-guided close-reading. In so doing, I show that Nietzsche sharply distinguished between humility and modesty, considering the former a vice (for certain types of people in certain contexts) and the latter a virtue (again, for certain types of people in certain contexts).

Interpreters have noticed that Nietzsche, in addition to sometimes being uproariously funny, reflects more on laughter and having a sense of humor than almost any other philosopher. Several scholars have further noticed that Nietzschean laughter sometimes seems to have an epistemic function. In this chapter, I assume that Nietzsche is a pluralist about the functions of humor and laughter, and seek to establish the uses he finds for them. I offer an interpretation according to which he tactically uses humor and (...) laughter for epistemic purposes. His epistemic aims include enabling inquiry (when faith and reverence might have forbidden it), achieving knowledge (for himself or for his reader), and abandoning error (again for himself or for his reader). Humor supports these goals by inducing contempt and the laughter that expresses (and sometimes also conjures) it. (shrink)

Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

Freud’s famous essay “The ‘Uncanny’” is often poorly understood. In this paper, I clear up the popular misconception that Freud identifies all uncanny phenomena with the return of repressed infantile complexes by showing that he offers not one but two theories of the uncanny: “return of the repressed,” and another explanation that has to do with the apparent confirmation of “surmounted primitive beliefs.” Of the two, I argue that it is the latter, more often overlooked theory that faces fewer serious (...) objections and carries greater explanatory power in respect of the uncanny.

What do humility, intellectual humility, and open-mindedness mean in the context of inter-group conflict? We spend most of our time with ingroup members, such as family, friends, and colleagues. Yet our biggest disagreements —— about practical, moral, and epistemic matters —— are likely to be with those who do not belong to our ingroup. An attitude of humility towards the former might be difficult to integrate with a corresponding attitude of humility towards the latter, leading to smug tribalism that masquerades (...) as genuine virtue. These potentially conflicting priorities have recently come to the fore because “tribal epistemology” has so thoroughly infected political and social discourse. Most research on these dispositions focuses on individual traits and dyadic peer-disagreement, with little attention to group membership or inter-group conflict. In this chapter, we dilate the social scale to address this pressing philosophical and social problem. (shrink)

I propose a definition of the uncanny: an anxious uncertainty about what is real caused by an apparent impossibility. First, I outline the relevance of the uncanny to art and aesthetics. Second, I disambiguate theoretical uses of ‘uncanny’ and establish the sense of the term that I am interested in—namely, an emotional state directed towards particular objects in the world which are characteristically eerie, creepy, and weird. Third, I look at Edgar Allan Poe’s ‘The Fall of the House of Usher’ (...) as a means of drawing out the conditions that I claim are essential to uncanny experiences, and then elaborate the terms of my proposed definition. Finally, I show how the definition accounts for two paradigmatic kinds of uncanny phenomena: cases of ‘uncanny resemblances’, which include twins, doppelgangers, and very lifelike representations of the human body; and unlikely coincidences of events.

Many scholars agree that the Internet plays a pivotal role in self-radicalization, which can lead to behaviours ranging from lone-wolf terrorism to participation in white nationalist rallies to mundane bigotry and voting for extremist candidates. However, the mechanisms by which the Internet facilitates self-radicalization are disputed; some fault the individuals who end up self-radicalized, while others lay the blame on the technology itself. In this paper, we explore the role played by technological design decisions in online self-radicalization in its myriad (...) guises, encompassing extreme as well as more mundane forms. We begin by characterizing the phenomenon of technological seduction. Next, we distinguish between top-down seduction and bottom-up seduction. We then situate both forms of technological seduction within the theoretical model of dynamical systems theory. We conclude by articulating strategies for combatting online self-radicalization.

This article considers two important problems for the idea that what we ought to do is determined by the balance of competing reasons. The problems are distinct, but the object of the article is to explore how they admit of a single solution. It is a consequence of this solution that objective reasons—facts that count in favor—are in an important sense less objective than they have consistently been assumed to be. This raises but does not answer the question as to (...) what evidence we ever had that reasons are as objective as has been assumed. (shrink)

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to (...) essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be. (shrink)

This paper addresses the question: ‘what makes reasons sufficient?’ and offers the answer, ‘being at least as weighty as the reasons for the alternatives’. The paper starts by introducing some of the reasons why sufficiency has seemed difficult to understand, particularly in epistemology, and some circumstantial evidence that this has contributed to more general problems in the epistemological literature. It then introduces the positive account of sufficiency, and explains how this captures sufficiency in both the practical and epistemic domains. Finally, (...) the paper shows how once we understand the nature of sufficiency, it is easy to predict the full variety of ways in which rationality – both of action and of belief – can be defeated.

It doesn’t seem possible to be a realist about the traditional Christian God while claiming to be able to reduce God talk in naturalistically acceptable terms. Reduction, in this case, seems obviously eliminativist. Many philosophers seem to think that the same is true of the normative—that reductive “realists” about the normative are not really realists about the normative at all, or at least, only in some attenuated sense. This paper takes on the challenge of articulating what it is that makes (...) reductive theological realism look hopeless, with the aim of explaining why we should think that the normative is relevantly different. Although it follows from my diagnosis that reductivists have their work cut out for them, I find nothing which suggests that the prospects for a successful reductive realism about the normative are in any way diminished—particularly for reductive views about reasons. Even reductivists, I argue, can at least aspire to a realism that is robust. (shrink)

Nietzsche talks about trust [vertraue*] and mistrust [misstrau*] in all of his published and authorized works, from The Birth of Tragedy to Ecce Homo. He refers to trust in 90 passages and mistrust in 101 – approximately ten times as often as he refers to resentment/ressentiment. Yet the scholarly literature on Nietzsche and trust includes just a handful of publications. Worse still, I have been unable to find a single publication devoted to Nietzsche and mistrust. This chapter aims to fill (...) the gap in the secondary literature by using digital humanities methods to systematically investigate the functions of trust and mistrust in Nietzsche’s writings. I argue that Nietzsche offers three main insights into trust and an additional two into mistrust. When it comes to trust, in his free spirit works, he reflects on the development of interpersonal trust, with an eye to situations in which trust is or is not reciprocated. He also criticizes some of the heuristics people use to identify trustworthy partners, especially the notion that all and only people with stable character are trustworthy. And perhaps Nietzsche’s most interesting thoughts about trust relate to self-trust, which he thinks is often unjustifiably undermined. When it comes to mistrust, although he regards generalized mistrust as a sign of bad character, he also thinks that harnessing mistrust can be valuable in at least two domains. One is morality, where we are disposed to accept traditional pieties and would benefit from turning a suspicious eye towards these pieties. The other is science, which systematizes both trust and mistrust in pursuit of the truth. (shrink)

Burgess (1997), building on Quine (1953), convincingly argued that claims in quantified modal logic cannot be understood as synonymous with or logically equivalent to claims about the analyticity of certain sentences. According to modal normativism, metaphysically necessary claims instead express or convey our actual semantic rules. In this paper, I show how the normativist can use Sidelle’s (1992a, 1995) neglected work on rigidity to account for two important phenomena in quantified modal logic: the necessity of identity and the substitutivity of (...) identicals into modal contexts. (shrink)

Nietzsche talks about shame [scham*, schmach*, schand*] in all of his published and authorized works, from The Birth of Tragedy to Ecce Homo. He refers to shame in over one hundred passages – at least five times as often as he refers to resentment/ressentiment. Yet the scholarly literature on Nietzsche and shame includes just a handful of publications, while the literature on Nietzsche and resentment includes over a thousand. Arguably, this disproportionate engagement has been driven by the fact that English (...) translations of Nietzsche’s writings systematically italicize and transliterate ‘ressentiment’ rather than treating it as the normal word it is. In any case, this chapter aims to fill the gap in the secondary literature by using digital humanities methods to systematically investigate the functions of shame in Nietzsche’s writings. I argue that Nietzsche is ambivalent about shame, depending on the function that it serves. There are four main functions. First, in a society of near-equals, it regulates interactions and incentives in ways that preserve game-theoretic equilibria. Second and relatedly, Nietzsche associates the capacity to experience nuanced and appropriate feelings of shame – and to anticipate them in others – with the pathos of distance, a virtue that he associates with nobility. Third, when shame is directed towards fixed aspects of human nature, it transforms those aspects into vices; by contrast, when it is directed towards malleable aspects of human nature, it may foster self-improvement and virtue. Nietzsche frequently laments the way that shame targets immutable aspects of ourselves. Finally and relatedly, Nietzsche casts counter-shame on those who would direct first-order shame on fixed aspects of human nature, as well as a paradoxical form of uplifting shame on their victims. If this is right, then Nietzsche does not offer a univocal verdict on shame. Instead, like many other emotions and emotional capacities, shame is inescapable, complex, and function-relative. (shrink)

Nietzsche talks about style [Stil and cognates] in all of his published and authorized works, from The Birth of Tragedy to Ecce Homo. He refers to style in over one hundred passages. Yet the scholarly literature on Nietzsche and style includes only a handful of publications, among them Derrida’s notorious Spurs: Nietzsche’s Styles (1978), which barely even engages with Nietzsche’s writings (see also Magnus 1991 and Babich 2011, 2012). Much of the rest of the literature is about Nietzsche’s style, rather (...) than about what he has to say about style. And none of it is comprehensive. In this paper, I aim to fill the gap in the secondary literature by using digital humanities methods to systematically investigate the functions of style in Nietzsche’s writings. I argue that, for Nietzsche style emerges in the context of a tradition in a community. It can then become personalized and individualized, though there are dangers with such innovations. One’s personal style is expressive of one’s psychology and physiology, and can go wrong by mis-expressing. Correlative with style, in Nietzsche’s conception, is the taste of the audience. Only those who share important psychological characteristics with the stylist will be able to fully comprehend their expressions. Finally, moving beyond aesthetics, Nietzsche connects style with moral and intellectual character, contending that the good stylist seeks recognition as such from those with good taste. (shrink)

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests. In this article, we challenge this proposition and argue that there (...) are several advantages of exploratory hypothesis tests that can make their results more compelling than those of confirmatory hypothesis tests. We also consider some potential disadvantages of exploratory hypothesis tests and conclude that their advantages can outweigh the disadvantages. We conclude that exploratory hypothesis tests avoid researcher commitment and researcher prophecy biases, reduce the probability of data fraud, are more appropriate in the context of unplanned deviations, facilitate inference to the best explanation, and allow peer reviewers to make additional contributions at the data analysis stage. In contrast, confirmatory hypothesis tests may lead to an inappropriate level of confidence in research conclusions, less appropriate analyses in the context of unplanned deviations, and greater bias and errors in theoretical inferences.

Keepsakes are nostalgic objects par excellence. We value keepsakes because they prompt nostalgic memories of the past. But perhaps more importantly, we also value them because they afford a feeling of contact with that which they remind us of. Drawing on work in philosophy and psychology, this chapter aims to give an account of the nature and value of keepsakes as nostalgic objects. Keepsakes, it argues, are objects that bear a material continuity with some person, event, or place from one’s (...) past to which one has a personal attachment. To understand the distinctive experiential value of keepsakes as nostalgic objects, however, the chapter argues that we need to invoke the imagination. Keepsakes manifest the presence of the past by prompting one to imaginatively project what a keepsake is historically connected with onto the object as one experiences it in the present. (shrink)

Could having a sense of humor be a virtue? In this paper, we argue for an affirmative answer to this question. Like other virtues, a sense of humor enhances and inhibits the expression of various emotions, especially amusement, contempt, trust, and hope. Someone possesses a virtuous sense of humor to the extent that they are well-disposed to appropriately enhance or inhibit these emotions in themselves and others through both embodied reactions (e.g., smiling, laughter, eyerolls) and language (e.g., telling jokes, understanding (...) others’ jokes, etc.). Regarding the aims or purposes of a sense of humor, we argue that a sense of humor aids both its bearer and other people who are socially connected to the bearer with coping, connection, capability, and criticism. If this is on the right track, then the value of a sense of humor is pluralistic: a sense of humor doesn’t do just one thing, but several things simultaneously. We then explore four contexts in which a sense of humor is especially needed, namely hardship, social relationships, social and political cooperation, and existential reflection. (shrink)

This chapter examines three recent empirical approaches to the study of moral motivation: moral foundations theory, deep pragmatism, and morality-as-cooperation. All three approaches conceptualize moral motivation as a suite of desires, emotions, sentiments, dispositions, values, and relationships that move people to think, judge, and act in accordance with morality. Moral foundations theory posits five or six basic foundations: care, fairness, loyalty, authority, sanctity, and sometimes liberty. People are thought to be emotionally attuned to each foundation, though some are more sensitive (...) to certain foundations than to others. Deep pragmatism posits that people tend to be motivated not only to promote their own narrow self interest but also the interests of their group. This can be seen as a sort of proto-morality, which has the capacity to develop into full-blown morality as one begins to conceive of one’s group in ever-broader terms. Finally, morality-as-cooperation is grounded in game theory and posits that cooperative solutions to non-zero-sum games are morally good, and that being motivated to seek out and implement such solutions is what it means to be morally motivated. Empirical evidence gathered in the last decade supports the morality-as-cooperation hypothesis, though more work is needed to further elaborate it and test its predictions. (shrink)

Few recent developments in information technology have been as hyped as blockchain, the first implementation of which was the cryptocurrency Bitcoin. Such hype furnishes ample reason to be skeptical about the promise of blockchain implementations, but I contend that there’s something to the hype. In particular, I think that certain blockchain implementations, in the right material, social, and political conditions, constitute excellent bases for common knowledge. As a case study, I focus on trust in election outcomes, where the ledger records (...) not financial transactions but vote tallies. I argue that blockchain implementations could foster warranted trust in vote tallies and thereby trust in the democratic process. Finally, I argue that if the promise of blockchain implementations as democratic infrastructure is to be realized, then democracies first need to ensure that these material, social, and political conditions obtain.

In a recent paper published in this journal, Giubilini, Douglas and Savulescu argue that we have given insufficient weight to the moral importance of fairness in our account of the best policies for non-medical exemptions to childhood immunization requirements. They advocate for a type of policy they call Contribution, according to which parents must contribute to important public health goods before their children can receive NMEs to immunization requirements. In this response, we argue that Giubilini, Douglas and Savulescu give insufficient (...) weight to the moral importance parental liberty in ways that count against their preferred type of NMEs policy and threaten public support for mandatory vaccination laws and public health initiatives generally.

Research notes of Mark Pettinelli about cognitive science, cognitive psychology.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We (...) Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Knowledge is power. Knowledge about human psychology is increasingly being produced using natural language processing (NLP) and related techniques. The power that accompanies and harnesses this knowledge should be subject to ethical controls and oversight. In this chapter, we address the ethical pitfalls that are likely to be encountered in the context of such research. These pitfalls occur at various stages of the NLP pipeline, including data acquisition, enrichment, analysis, storage, and sharing. We also address secondary uses of the results (...) and tools developed through psychometric NLP, such as profit-driven targeted advertising, political campaigns, and domestic and international psyops. Along the way, we reflect on potential ethical guidelines and considerations that may help researchers navigate these pitfalls. (shrink)

This collection of articles is almost all of the psychological writings of Mark Pettinelli.

Virtues are dispositions that make their bearers admirable. Dispositions can be studied scientifically by systematically varying whether their alleged bearers are in (or take themselves to be in) the dispositions' eliciting conditions. In recent decades, empirically-minded philosophers looked to social and personality psychology to study the extent to which ordinary humans embody dispositions traditionally considered admirable in the Aristotelian tradition. This led some to conclude that virtues are not attainable ideals, and that we should focus our ethical reflection and efforts (...) more on jerry-rigging our environments than on improving our characters. Most virtue ethicists resisted this reorientation. However, much of the scientific evidence on which the controversy was based has failed to replicate, raising the question of how much faith we should place in methodologically suspect studies. In this paper, I assess the state of the debate and recommend best practices for a renewed interdisciplinary investigation of virtues and vices in which philosophical expertise related to conceptualization and theorizing is essentially intertwined with scientific expertise related to operationalization, measurement, and statistics.

One of the gravest charges that has been brought against Hume’s essay “Of the Standard of Taste” is that of circularity. Hume is accused of defining good art in terms of “true judges,” and of defining true judges in terms of their ability to judge good art. First, I argue that Hume avoids circularity since he offers a way of identifying good art that is logically independent of the verdict of true judges. Second, I argue that this clarifies an enduring (...) puzzle in the scholarship on Hume’s essay: why he appears to offer not one but two standards of taste. Hume’s standard does not consist of general rules; however, Hume needs general rules to establish that some individuals’ tastes are more “delicate” than others’. (shrink)

Scientists often adjust their significance threshold during null hypothesis significance testing in order to take into account multiple testing and multiple comparisons. This alpha adjustment has become particularly relevant in the context of the replication crisis in science. The present article considers the conditions in which this alpha adjustment is appropriate and the conditions in which it is inappropriate. A distinction is drawn between three types of multiple testing: disjunction testing, conjunction testing, and individual testing. It is argued that alpha (...) adjustment is only appropriate in the case of disjunction testing, in which at least one test result must be significant in order to reject the associated joint null hypothesis. Alpha adjustment is inappropriate in the case of conjunction testing, in which all relevant results must be significant in order to reject the joint null hypothesis. Alpha adjustment is also inappropriate in the case of individual testing, in which each individual result must be significant in order to reject each associated individual null hypothesis. The conditions under which each of these three types of multiple testing is warranted are examined. It is concluded that researchers should not automatically assume that alpha adjustment is necessary during multiple testing. Illustrations are provided in relation to joint studywise hypotheses and joint multiway ANOVAwise hypotheses. (shrink)

In Naked, Krista K. Thomason offers a multi-faceted account of shame, covering its nature as an emotion, its positive and negative roles in moral life, its association with violence, and its provocation through invitations to shame, public shaming, and stigmatization. Along the way, she reflects on a range of examples drawn from literature, memoirs, journalism, and her own imagination. She also considers alternative views at length, draws a wealth of important distinctions, and articulates many of the most intuitive objections to (...) her own view in order to defend it more thoroughly. As such, the book’s subtitle, The Dark Side of Shame and Moral Life, undersells its scope and ambition. This is an exploration not just of shame’s dark side but a kaleidoscopic appreciation of both the nature and the (dis)value of shame and shaming. Somewhat undercutting this breadth, Thomason relies heavily on Kantian intuitions about equal respect and recognition for persons and their dignity; in several key arguments, she tells us to disregard predictable and systematic consequences of emotions, practices, and institutions so that we can better focus on their constitutive or internal aspects. Of course, every philosopher inevitably brings theoretical commitments to bear when writing about moral psychology, but non-Kantian readers should be forewarned that — despite the fact that Thomason says that she does “not assume any particular moral theory” — her ethical conclusions about shaming and stigmatizing are likely to be plausible only to those who are already snugly tied into a web of “Kantian commitments” (p. 9).

The Razor says: do not multiply entities without necessity! The Laser says: do not multiply fundamental entities without necessity! Behind the Laser lies a deep insight. This is a distinction between the costs and the commitments of a theory. According to the Razor, every commitment is a cost. Not so according to the Laser. According to the Laser, derivative entities are an ontological free lunch: that is, they are a commitment without a cost. Jonathan Schaffer (2015) has argued that the (...) Laser should replace the Razor. In Sections 2-4 we shall discuss and argue against Schaffer’s arguments for replacing the Razor with the Laser. Schaffer considers several objections to his views, and in Sections 5-7 we shall argue that Schaffer does not deal successfully with two of them. In Section 8 we shall present a probabilistic argument for the Laser. However, the argument has a limitation and does not support the replacement of the Razor with the Laser. Indeed, it supports only the claim that, given certain assumptions, the multiplication of explanatorily relevant derivative entities does not matter; but, as we argue in the same section, there is an argument that multiplying explanatorily superfluous derivative entities does makes a theory less rationally acceptable. Our conclusion is that the Laser cannot replace the Razor and that derivative entities are not an ontological free lunch. (shrink)

Remembering that there’s a difference between intellectual and perceptual attention can help us avoid miscommunication due to meaning different things by the same terms, which has been a particular problem during the last hundred years or so of the study of attention. I demonstrate this through analyzing in depth one such miscommunication that occurred in a philosophical criticism of the influential psychological text, Inattentional Blindness. But after making the distinction between perceptual attention and intellectual attention, and after making an effort (...) to keep this distinction in mind, we are still faced with the problem of specifying what makes intellectual attention distinct from perceptual attention. In the second half of this article, I discuss the range of proposals about how to understand intellectual attention that are present in the literature, and the problems with them. I do this with the aim of stimulating further discussion about how best to conceptualize intellectual attention, although I do not settle that further question within this paper. (shrink)

The purpose of this paper is to conceptualize and explore what I shall call the Common Subject Problem for ethics. The problem is that there seems to be no good answer to what property everyone who makes moral claims could be talking and thinking about. The Common Subject Problem is not a new problem; on the contrary, I will argue that it is one of the central animating concerns in the history of both metaethics and normative theory. But despite its (...) importance, the Common Subject Problem is essentially invisible on many contemporary ways of carving up the problems of metaethics and normative ethical theory. My aim, therefore, is to make progress – in part by naming the problem, but also by beginning to sketch out the contours of what gives the problem its force, by distinguishing between different paths of response to the problem and assessing some of their chief merits, and finally, by distinguishing the Common Subject Problem from another problem with which it has come to be conflated. This nearby problem is the Moral Twin Earth Problem. Whereas the Common Subject Problem is a problem about what property ‘wrong’ could refer to, the Moral Twin Earth Problem is a problem about how ‘wrong’ could refer to it. The upshot of the paper, therefore, is to rescue one of the historically significant problems in normative ethics and metaethics – a problem that is essentially about normative semantics – from the illusion that has persisted over the last twenty years that it is really, somehow, a problem about metasemantics. Once we have reclaimed this problem, we can see that it could still be a problem even if there are no distinctively metasemantic problems in metaethics at all, that it is a problem faced by a wider variety of views, and that the space of possible solutions is much wider and more interesting for normative theory, moral psychology, and moral epistemology.
