In “Of Personal Identity”, Hume attempts to understand why we ordinarily believe in persistent selves. He proposes that this ontological commitment depends on illusions and fictions: the imagination tricks us into supposing that an unchanging core self remains static through the flux and change of experience. Recent work in cognitive science provides a good deal of support for Hume’s hypothesis that common beliefs about the self are founded on psychological biases rather than rational insight or evidence. We naturally believe in (...) personal persistence, according to this emerging research, because we are prone to categorize the world in terms of hidden essences and structure our lives in terms of whole life stories.

The ethical question is whether university mask mandates should be relaxed. I argue that the use of face masks by healthy individuals has uncertain benefits, which potential harms may outweigh, and should therefore be voluntary. Systematic reviews by the World Health Organization (WHO) and Cochrane Acute Respiratory Infections concluded that the use of face masks by healthy individuals in the community lacks effectiveness in reducing viral transmission based on moderate-quality evidence. The only two randomized controlled trials of face masks published (...) during the pandemic found little to no benefit. Without high-quality evidence, it is difficult to justify a requirement rather than a recommendation. Notwithstanding, one might argue that the precautionary principle justifies mask mandates. If the precautionary principle can justify implementing mask mandates due to the risk of forgoing possible benefit, then it might also be able to justify not implementing mask mandates due to the risk of potential harm caused by the intervention. It is commonly thought that there is little to lose from the use of face masks, but this is not necessarily true. It is possible that masks have done more harm than good. (shrink)

Is PDP Connectionism compatible with Cognitive Linguistics? It is unfortunate that this question has not received the attention it deserves, since at stake is the very possibility of a unified "West Coast Cognitive Science" approach to language. Part I of this paper argues that a systematic approach to the question of compatibility must involve an enumeration and analysis of the general principles used by each research program in their linguistic explanations. This approach is carried out in Parts II and III, (...) and the conclusion is that the explanatory principles of PDP Connectionism are fundamentally data-driven, whereas those of Cognitive Linguistics rely essentially on structure that the mind contributes to language use. Part IV presents several computational models of metaphor and analogy as case studies of the practical difficulties involved in reconciling these two frameworks. Finally, Part V examines the philosophical foundations of their respective explanatory strategies in order to get a clearer view of the theoretical obstacles to a unified account. (shrink)

In the Natural history of religion, Hume attempts to understand the origin of our folk belief in gods and spirits. These investigations are not, however, purely descriptive. Hume demonstrates that ontological commitment to supernatural agents depends on motivated reasoning and illusions of control. These beliefs cannot, then, be reflectively endorsed. This proposal must be taken seriously because it receives support from recent work on our psychological responses to uncertainty. It also compares quite favorably with its main competitors in the cognitive (...) science of religion. (shrink)

Approximation involves representing things in ways that might be close to the truth but are nevertheless false. Given the widespread reliance on approximations in science and everyday life, here we ask whether it is conceptually possible for false approximations to qualify as knowledge. According to the factivity account, it is impossible to know false approximations, because knowledge requires truth. According to the representational adequacy account, it is possible to know false approximations, if they are close enough to the truth for (...) present purposes. In this paper, we adopt an experimental methodology to begin testing these two theories. When an agent provides a false and practically inadequate answer, both theories predict that people will deny knowledge. But the theories disagree about an agent who provides a false but practically adequate answer: the factivity hypothesis again predicts knowledge denial, whereas the representational adequacy hypothesis predicts knowledge attribution. Across two experiments, our principal finding was that people tended to attribute knowledge for false but practically adequate answers, which supports the representational adequacy account. We propose an interpretation of existing findings that preserves a conceptual link between knowledge and truth. According to this proposal, truth is not necessary for knowledge, but it is a feature of prototypical knowledge. (shrink)

We distinguish between two categories of belief—thin belief and thick belief—and provide evidence that they approximate genuinely distinct categories within folk psychology. We use the distinction to make informative predictions about how laypeople view the relationship between knowledge and belief. More specifically, we show that if the distinction is genuine, then we can make sense of otherwise extremely puzzling recent experimental findings on the entailment thesis (i.e. the widely held philosophical thesis that knowledge entails belief). We also suggest that the (...) distinction can be applied to debates in the philosophy of mind and metaethics. (shrink)

The purpose of this chapter is to provide a guide for conducting thought experiments in epistemology effectively. The guide raises several considerations for best practices when using this research method. Several weaknesses in the way thought experiments are conducted are also identified and several suggestions are reviewed for how to improve them. Training in these research techniques promotes more productive scholarship in epistemology, saves time and resources wasted on less efficient approaches, and reduces the risk that researchers are fooling themselves (...) when they use thought experiments in philosophy.

We accomplish three things in this paper. First, we provide evidence that the motivational internalism/externalism debate in moral psychology could be a false dichotomy born of ambiguity. Second, we provide further evidence for a crucial distinction between two different categories of belief in folk psychology: thick belief and thin belief. Third, we demonstrate how careful attention to deep features of folk psychology can help diagnose and defuse seemingly intractable philosophical disagreement in metaethics.

It is widely accepted in epistemology that knowledge is factive, meaning that only truths can be known. We argue that this theory creates a skeptical challenge: because many of our beliefs are only approximately true, and therefore false, they do not count as knowledge. We consider several responses to this challenge and propose a new one. We propose easing the truth requirement on knowledge to allow approximately true, practically adequate representations to count as knowledge. In addition to addressing the skeptical (...) challenge, this view also coheres with several previous theoretical proposals in epistemology. (shrink)

In Book I, part iv, section 2 of the Treatise, "Of scepticism with regard to the senses," Hume presents two different answers to the question of how we come to believe in the continued existence of unperceived objects. He rejects his first answer shortly after its formulation, and the remainder of the section articulates an alternative account of the development of the belief. The account that Hume adopts, however, is susceptible to a number of insurmountable objections, which motivates a reassessment (...) of his original proposal. This paper defends a version of Hume's initial explanation of the belief in continued existence and examines some of its philosophical implications. (shrink)

Pedagogy is a pillar of human culture and society. Telling each other information and showing each other how to do things comes naturally to us. A strong case has been made that declarative knowledge is the norm of assertion, which is our primary way of telling others information. This article presents an analogous case for the hypothesis that procedural knowledge is the norm of instructional demonstration, which is a primary way of showing others how to do things. Knowledge is the (...) norm of telling and showing. It is the prime pedagogical principle. (shrink)

We must rethink the status of Hume’s science of emotions. Contemporary philosophers typically dismiss Hume’s account on the grounds that he mistakenly identifies emotions with feelings. But the traditional objections to Hume’s feeling theory are not as strong as commonly thought. Hume makes several important contributions, moreover, to our understanding of the operations of the emotions. His claims about the causal antecedents of the indirect passions receive support from studies in appraisal theory, for example, and his suggestions concerning the social (...) dimensions of self-conscious emotions can help guide future research in this field. His dual-component hypothesis concerning the processing of emotions, furthermore, suggests a compromise solution to a recalcitrant debate in cognitive science. Finally, Hume’s proposals concerning the motivational influences of pride, and the conventional nature of emotional display rules, are vindicated by recent work in social psychology. (shrink)

It is often thought that judgments about what we ought to do are limited by judgments about what we can do, or that “ought implies can.” We conducted eight experiments to test the link between a range of moral requirements and abilities in ordinary moral evaluations. Moral obligations were repeatedly attributed in tandem with inability, regardless of the type (Experiments 1–3), temporal duration (Experiment 5), or scope (Experiment 6) of inability. This pattern was consistently observed using a variety of moral (...) vocabulary to probe moral judgments and was insensitive to different levels of seriousness for the consequences of inaction (Experiment 4). Judgments about moral obligation were no different for individuals who can or cannot perform physical actions, and these judgments differed from evaluations of a non-moral obligation (Experiment 7). Together these results demonstrate that commonsense morality rejects the “ought implies can” principle for moral requirements, and that judgments about moral obligation are made independently of considerations about ability. By contrast, judgments of blame were highly sensitive to considerations about ability (Experiment 8), which suggests that commonsense morality might accept a “blame implies can” principle. (shrink)

The belief norm of academic publishing states that researchers should believe certain claims they publish. The purpose of this paper is to defend the belief norm of academic publishing. In its defense, the advantages and disadvantages of the belief norm are evaluated for academic research and for the publication system. It is concluded that while the norm does not come without costs, academic research systemically benefits from the belief norm and that it should be counted among those that sustain the (...) practice of academic publishing.

The aesthetic skeptic maintains that it is futile to dispute about taste. One and the same work of art might appear beautiful to one person but repellent to another, and we have no reason to prefer one or another of these conflicting verdicts. Hume argues that the skeptic, however, moves too quickly. The crucial question is whether qualified critics will agree on their evaluations. And the skeptic fails to provide sufficient evidence that their verdicts will diverge. We have reason to (...) expect that a consensus will emerge over time, moreover, since aesthetic values are grounded on universal principles of human nature. Skeptics might doubt that there is a natural basis for a standard of taste, but this proposal is supported by recent work in experimental aesthetics and cognitive science. (shrink)

According to one picture of the mind, decisions and actions are largely the result of automatic cognitive processing beyond our ability to control. This picture is in tension with a foundational principle in ethics that moral responsibility for behavior requires the ability to control it. The discovery of implicit attitudes contributes to this tension. According to the ability argument against moral responsibility, if we cannot control implicit attitudes, and implicit attitudes cause behavior, then we cannot be morally responsible for that (...) behavior. The purpose of this paper is to refute the ability argument. Drawing on both scientific evidence in cognitive science and philosophical arguments in ethics and action theory, I argue that it is invalid and unsound because current evidence is insufficient to establish the premises that implicit attitudes are uncontrollable, that they significantly cause behavior, that responsibility always requires ability, and that even if uncontrollable attitudes did fully cause behavior, this entails that the behavior they cause is uncontrollable. The rejection of the ability argument questions the priority of the unconscious over the conscious mind in cognitive science, deprioritizes ability in theories of moral responsibility in ethics, and provides a strong reason to uphold moral responsibility for implicitly biased behavior.

Experimental philosophers have empirically challenged the connection between intuition and philosophical expertise. This paper reviews these challenges alongside other research findings in cognitive science on expert performance and argues for three claims. First, evidence taken to challenge philosophical expertise may also be explained by the well-researched failures and limitations of genuine expertise. Second, studying the failures and limitations of experts across many fields provides a promising research program upon which to base a new model of philosophical expertise. Third, a model (...) of philosophical expertise based on the limitations of genuine experts may suggest a series of constraints on the reliability of professional philosophical intuition. Even when the experts all agree, they may well be mistaken. — Bertrand Russell, On the Value of Scepticism. (shrink)

In ‘A Dialogue’, Hume offers an important reply to the moral skeptic. Skeptics traditionally point to instances of moral diversity in support of the claim that our core values are fixed by enculturation. Hume argues that the skeptic exaggerates the amount of variation in moral codes, however, and fails to adopt an indulgent stance toward attitudes different from ours. Hume proposes a charitable interpretation of moral disagreement, moreover, which traces it back to shared principles of human nature. Contemporary philosophers attempt (...) to locate examples of moral variability that cannot be accommodated in this way. But they are no more successful than their predecessors. Moral skeptics have not found a single case of moral diversity that is resistant to the Humean strategy. (shrink)

Philosophers are divided on whether it is possible to intend believed-impossible outcomes. Several thought experiments in the action theory literature suggest that this is conceptually possible, though they have not been tested in ordinary social cognition. We conducted three experiments to determine whether, on the ordinary view, it is conceptually possible to intend believed-impossible outcomes. Our findings indicate that participants firmly countenance the possibility of intending believed-impossible outcomes, suggesting that it is conceptually possible to intend to do something that one (...) believes is impossible.

David Hume endorses three claims that are difficult to reconcile: (1) sympathy with those in distress is sufficient to produce compassion towards their plight, (2) adopting the general point of view often requires us to sympathize with the pain and suffering of distant strangers, but (3) our care and concern is limited to those in our close circle. Hume manages to resolve this tension, however, by distinguishing two types of sympathy. We feel compassion towards those around us because associative sympathy (...) causes us to mirror their pain and suffering, but our ability to enter into the afflictions of those remote from us involves cognitive sympathy and merely requires us to reflect upon how we would feel in their shoes. This hybrid theory of sympathy receives support from recent work on affective mirroring and cognitive pretense. Hume’s account should appeal to contemporary researchers, therefore, who are interested in the nature of moral imagination. (shrink)

Hume is an experimental philosopher who attempts to understand why we think, feel, and act as we do. But how should we evaluate the adequacy of his proposals? This chapter examines Hume’s account from the perspective of interdisciplinary work in cognitive science.

Hume maintains that the boundaries of morality are widely drawn in everyday life. We routinely blame characters for traits that we find disgusting, on this account, as well as those which we perceive as being harmful. Contemporary moral psychology provides further evidence that human beings have a natural tendency to moralize traits that produce feelings of repugnance. But recent work also demonstrates a significant amount of individual variation in our sensitivities to disgust. We have sufficient reason to bracket this emotion, (...) therefore, when adopting the general point of view: if we allow idiosyncratic affective responses to shape our fully considered moral judgments, we could no longer reasonably expect spectators with different sensitivities to agree with us. (shrink)

Many have argued we have a moral obligation to assist others in need, but given the scope of global suffering, how far does this obligation extend? According to one traditional philosophical view, the obligation to help others is limited by our ability to help them, or by the principle that “ought implies can”. This view is primarily defended on the grounds that it is a core principle of commonsense moral psychology. This paper reviews findings from experimental philosophy in cognitive science (...) demonstrating that “ought implies can” is rejected by moral psychology. Researchers find that moral obligations are ascribed to agents who cannot fulfill them, suggesting that moral requirements do sometimes extend beyond what we are able to do. This research furthers our understanding of moral obligation, identifies an important need for further cross-cultural work in moral psychology, and demonstrates a way in which scientific experimentation can be applied to improve upon the conceptual analysis of important philosophical concepts in normative ethics.

This is the general introduction to the edited collection "A companion to Experimental Philosophy".

We report two experiments exploring the perception of how contemporary philosophy is often conducted. We find that (1) participants associate philosophy with the practice of conducting thought experiments and collating intuitions about them, and (2) that this form of inquiry is viewed much less favourably than the typical form of inquiry in psychology: research conducted by teams using controlled experiments and observation. We also found (3) an effect whereby relying on intuition is viewed more favorably in the context of team (...) inquiry than in individual inquiry and (4) that greater prior exposure to philosophy lowered one’s opinion of inquiry driven by intuitions and thought experiments. Finally with respect to participant gender, we found that (5) women favored observation over intuition more than men did, and (6) tended to view a question pursued by a research team as more important than men viewed it.

Moderate scientism is the view that empirical science can help answer questions in nonscientific disciplines. In this paper, we evaluate moderate scientism in philosophy. We review several ways that science has contributed to research in epistemology, action theory, ethics, philosophy of language, and philosophy of mind. We also review several ways that science has contributed to our understanding of how philosophers make judgments and decisions. Based on this research, we conclude that the case for moderate philosophical scientism is strong: scientific (...) practice has promoted significant progress in philosophy and its further development should be welcomed and encouraged.

In Book I, Part I, Section VII of the Treatise, Hume sets out to settle, once and for all, the early modern controversy over abstract ideas. In order to do so, he tries to accomplish two tasks: (1) he attempts to defend an exemplar-based theory of general language and thought, and (2) he sets out to refute the rival abstraction-based account. This paper examines the successes and failures of these two projects. I argue that Hume manages to articulate a plausible (...) theory of general ideas; indeed, a version of his account has defenders in contemporary cognitive science. But Hume fails to refute the abstraction-based account, and as a result, the early modern controversy ends in a stalemate, with both sides able to explain how we manage to speak and think in general terms. Although Hume fails to settle the controversy, he nevertheless advances it to a point from which we have yet to progress: the contemporary debate over abstract ideas in cognitive science has stalled on precisely this point.

Rini 2015 [Synthese 192, (2): 431-452] claims to have identified a methodological flaw that invalidates the results of two experimental studies [Schwitzgebel & Cushman (2012) Mind and Language 27, (2): 135-153; Tobia, Buckwalter & Stich (2013) Philosophical Psychology 26, (5): 629–638] demonstrating order effects in professional philosophical intuition. This conclusion is reached on the basis of unsupported empirical premises for which no evidence is given. Subsequent findings in experimental cognitive science further reveal this as unsupported speculation.

There is an extensive literature in social choice theory studying the consequences of weakening the assumptions of Arrow's Impossibility Theorem. Much of this literature suggests that there is no escape from Arrow-style impossibility theorems unless one drastically violates the Independence of Irrelevant Alternatives (IIA). In this paper, we present a more positive outlook. We propose a model of comparing candidates in elections, which we call the Advantage-Standard (AS) model. The requirement that a collective choice rule (CCR) be rationalizable by the (...) AS model is in the spirit of but weaker than IIA; yet it is stronger than what is known in the literature as weak IIA (two profiles alike on x, y cannot have opposite strict social preferences on x and y). In addition to motivating violations of IIA, the AS model makes intelligible violations of another Arrovian assumption: the negative transitivity of the strict social preference relation P. While previous literature shows that only weakening IIA to weak IIA or only weakening negative transitivity of P to acyclicity still leads to impossibility theorems, we show that jointly weakening IIA to AS rationalizability and weakening negative transitivity of P leads to no such impossibility theorems. Indeed, we show that several appealing CCRs are AS rationalizable, including even transitive CCRs. (shrink)

There are two major puzzles in Hume’s epistemology. The first involves Hume’s fall into despair in the conclusion of Book One of the Treatise. When Hume reflects back upon the results of his research, he becomes so alarmed that he nearly throws his books and papers into the fire. Why did his investigations push him towards such intense skeptical sentiments? What dark discoveries did he make? The second puzzle concerns the way in which Hume emerges from this skeptical crisis and (...) proceeds with his investigations. Why the sudden change of heart? What accounts for the return of hope? Each of these puzzles represents a serious challenge to traditional approaches to Hume’s epistemology. A proper solution to them requires a careful examination of Hume’s claims about the untrustworthiness of our cognitive faculties as well as his strategy for improving their performance. (shrink)

It is commonly thought that Hume endorses the claim that causal cognition can be fully explained in terms of nothing but custom and habit. Associative learning does, of course, play a major role in the cognitive psychology of the Treatise. But Hume recognizes that associations cannot provide a complete account of causal thought. If human beings lacked the capacity to reflect on rules for judging causes and effects, then we could not (as we do) distinguish between accidental and genuine regularities, (...) and Hume could not (as he does) carry out his science of human nature. One might reply that what appears to be rule-governed behavior might emerge from associative systems that do not literally employ rules. But this response fails: there is a growing consensus in cognitive science that any adequate account of causal learning must invoke active, controlled cognitive processes. (shrink)

Hume argues that we succumb to the vice of prejudice when we fail to correct negative generalizations about social groups in the face of counter-evidence. We are blameworthy for these biases, moreover, even if they are unavoidable. Hume’s theory of doxastic responsibility entails that his own racial prejudices are deserving of condemnation. In contrast, contemporary vice epistemologists are more inclined to absolve agents of culpability for prejudices beyond their control.

Research on the capacity to understand others' minds has tended to focus on representations ofbeliefs,which are widely taken to be among the most central and basic theory of mind representations. Representations ofknowledge, by contrast, have received comparatively little attention and have often been understood as depending on prior representations of belief. After all, how could one represent someone as knowing something if one does not even represent them as believing it? Drawing on a wide range of methods across cognitive science, (...) we ask whether belief or knowledge is the more basic kind of representation. The evidence indicates that nonhuman primates attribute knowledge but not belief, that knowledge representations arise earlier in human development than belief representations, that the capacity to represent knowledge may remain intact in patient populations even when belief representation is disrupted, that knowledge (but not belief) attributions are likely automatic, and that explicit knowledge attributions are made more quickly than equivalent belief attributions. Critically, the theory of mind representations uncovered by these various methods exhibits a set of signature features clearly indicative of knowledge: they are not modality-specific, they are factive, they are not just true belief, and they allow for representations of egocentric ignorance. We argue that these signature features elucidate the primary function of knowledge representation: facilitating learning from others about the external world. This suggests a new way of understanding theory of mind – one that is focused on understanding others' minds in relation to the actual world, rather than independent from it. (shrink)

For children, the collateral damage of the COVID-19 pandemic response has been considerable. In this paper, we use the framework of evidence-based medicine to argue that child abuse is another negative side effect of COVID-19 lockdowns. While it was certain that school closures would have profound social and economic costs, it remains uncertain whether they have any effect on COVID-19 transmission. There is emerging evidence that lockdowns significantly worsened child abuse on a global scale. Low-income and middle-income countries are particularly (...) vulnerable to increases in child abuse. The best available external evidence from systematic research during the pandemic demonstrates an increase in the risk of child maltreatment, an increase in child maltreatment hospitalisations and a concerning decrease in official child maltreatment referrals. The paradoxical phenomenon of increased hospitalisations and decreased reports is unlikely to be explained by a genuine decrease in child abuse. We conclude that lockdowns have an unacceptably high risk of negative side effects for children, as evidenced by child abuse, the true extent of which appears to be masked by lockdown-related disruptions to schools and other surveillance systems. The desire for a sense of security may be a tempting bias towards emphasising the resilience of children, but it is ethically problematic to push children towards abuse in the name of public health. It is our view that the collateral damage of prolonged school closures for society’s most vulnerable members is a powerful ethical consideration against any pandemic response which involves their use.

Evidence-based medicine is a clinical decision-making framework which makes claims about what physicians ought to do. Though heralded as the cutting edge of medical science, evidence-based medicine is a value-laden normative theory which implicitly depends on substantive views regarding what is morally good or right. In this paper, I provide an ethical analysis of evidence-based medicine. I consider its normative underpinnings in three ethical theories: utilitarianism, Kantian deontology, and virtue ethics. In the face of uncertainty, evidence-based medicine endorses expected utility (...) theory using the best available evidence in order to avoid doing more harm than good. In accordance with the Kantian respect for individuals as ends in themselves, evidence-based medicine calls for integrating the values and preferences of the patient. De-emphasizing intuition, clinical expertise, and pathophysiologic rationale emphasizes the need for the intellectual virtues of curiosity, critical thinking, and courage. Evidence-based medicine is a successful clinical practice that can be morally justified by all three major ethical theories. Although its focus on maximizing good health outcomes and integrating respect for individual patients has been emphasized, the role of the intellectual virtues in evidence-based medicine remains highly under-explored.

Lockdowns, or modern quarantines, involve the use of novel restrictive non-pharmaceutical interventions (NPIs) to suppress the transmission of COVID-19. In this paper, I aim to critically analyze the emerging history and philosophy of lockdowns, with an emphasis on the communication of health evidence and risk for informing policy decisions. I draw a distinction between evidence-based and modeling-based decision-making. I argue that using the normative framework of evidence-based medicine would have recommended against the use of lockdowns. I first review the World (...) Health Organization’s evidence-based pandemic preparedness plans for respiratory viruses. I then provide a very brief history of COVID-19 modeling, which was cited as justification for the use of lockdowns in the U.K., the U.S., and much of the world. I focus on the so-called Imperial College model designed by Neil Ferguson et al. as well as the so-called Oxford model designed by José Lourenço et al. I analyze the evidence-based pandemic response known as ‘mitigation’, and I compare it with Ferguson et al.’s experimental strategy known as ‘suppression’. I summarize the strengths and weaknesses of these strategies based on their diametric aims and each model’s parametric assumptions. Based on my critical analysis of the suppression strategy, I attempt to expose what has been called the ‘logic of lockdowns’, which Sunetra Gupta of the Oxford model group has suggested is flawed. Finally, I consider Trisha Greenhalgh’s objection to evidence-based policy based on the precautionary principle, and I attempt to offer a response. I conclude with a brief narrative review of the emerging randomized evidence on restrictive NPIs, which seems to support my claim that mitigation was the strategy that would have been recommended by evidence-based medicine. If this is true, then COVID-19 modeling may serve as an important reminder of the enduring lesson of evidence-based medicine: that one should always ‘Trust the Evidence!’ for better health policy.

This essay considers a mixed-effects modeling practice and its implications for the philosophical debate surrounding reductive explanation. Mixed-effects modeling is a species of the multilevel modeling practice, where a single model incorporates simultaneously two (or even more) levels of explanatory variables to explain a phenomenon of interest. I argue that this practice makes the position of explanatory reductionism held by many philosophers untenable because it violates two central tenets of explanatory reductionism: single-level preference and lower-level obsession.

Polger and Shapiro (2016) claim that unlike human-made artifacts cases of multiple realization in naturally occurring systems are uncommon. Drawing on cases from systems biology, I argue that multiple realization in naturally occurring systems is not as uncommon as Polger and Shapiro initially thought. The relevant cases, which I draw from systems biology, involve generalizable design principles called network motifs which recur in different organisms and species and perform specific functions. I show that network motifs with entirely different underlying causal (...) structures can perform the same function of interest. The article also considers the scope problem of multiple realization.

Nearly all success is due to some mix of ability and luck. But some successes we attribute to the agent’s ability, whereas others we attribute to luck. To better understand the criteria distinguishing credit from luck, we conducted a series of four studies on knowledge attributions. Knowledge is an achievement that involves reaching the truth. But many factors affecting the truth are beyond our control and reaching the truth is often partly due to luck. Which sorts of luck are compatible (...) with knowledge? We find that knowledge attributions are highly sensitive to lucky events that change the explanation for why a belief is true. By contrast, knowledge attributions are surprisingly insensitive to lucky events that threaten but ultimately fail to change the explanation for why a belief is true. These results shed light on our concept of knowledge, help explain apparent inconsistencies in prior work on knowledge attributions, and constitute progress toward a general understanding of the relation between success and luck.

The tendency to draw mind-brain dichotomies and evaluate mental disorders dualistically arises in both laypeople and mental health professionals, leads to biased judgments, and contributes to mental health stigmatization. This paper offers a theory identifying an underlying source of these evaluations in social practice. According to this theory, dualistic evaluations are rooted in two mechanisms by which we represent and evaluate the beliefs of others in folk psychology and theory of mind: the doxastic conception of mental disorders and doxastic voluntarism.

Tracing these origins contributes to our understanding of mental state representation in cognitive science and philosophy of psychiatry, the concept of belief in philosophy of mind, and may help improve patient experience and treatment in light of social stigmatization and bias toward mental illness.

The infinite judgement has long been forgotten and yet, as I am about to demonstrate, it may be urgent to revive it for its critical and productive potential.

It is through infinite judgements that we reach the principle of transcendental logic, in the depths of which all reality can (...) emerge in its material and sensible singularity, making possible all generalization and formal abstraction.

Centuries ago, Descartes and Locke initiated a foundational debate in epistemology over the relationship between knowledge, on the one hand, and practical factors, on the other. Descartes claimed that knowledge and practice are fundamentally separate. Locke claimed that knowledge and practice are fundamentally united. After a period of dormancy, their disagreement has reignited on the contemporary scene. Latter-day Lockeans claim that knowledge itself is essentially connected to, and perhaps even constituted by, practical factors such as how much is at stake, (...) how important the situation is, or how one should act. Latter-day Cartesians claim, by contrast, that knowledge is entirely constituted by truth-related factors such as truth, belief, and evidence. Each side has supported its case with claims about patterns in ordinary behavior and knowledge judgments. Lockeans argue that these patterns are best explained by positing a fundamental and direct link between knowledge and practical factors. Cartesians argue that the patterns can be equally well explained by positing an indirect link, entirely mediated by the traditional factors of truth, belief, and evidence, thereby rendering the Lockean hypothesis unnecessary. We argue that Cartesians are right about some practical factors, in particular stakes and how important a situation is, which have, at best, a modest indirect relationship to knowledge. However, Lockeans are right about actionability: whether a person should pursue a course of action is unquestionably very powerfully and directly connected to knowledge. (shrink)

This dissertation defends an ideal of democratic citizenship inspired by John Dewey’s theory of human flourishing, or “growth.” In its emphasis on the interrelatedness of individual development and social progress, Deweyan growth orients us toward a morally substantive approach to addressing the important question of how diverse citizens can live together well. I argue, however, that Dewey’s understanding of growth as a process by which conflicting interests, beliefs, and values are integrated into a more unified whole—both within the community and (...) within the self—is inadequate to the radical pluralism characteristic of contemporary liberal democratic societies. Given the pragmatist insight into the crucial role of socialization in identity formation, the problem with conceptualizing the ideal self as an integrated unity is that, for many, the complexity and diversity of our social world presents an insuperable obstacle to sustaining a unified (or always unifying) self. Most of us have multiple “selves” forged by the various groups with whom we identify and the often incongruous roles we play in our personal, professional, and/or public lives. Hence I offer a reconstruction of Deweyan growth that accounts for persistent yet positively valued diversity, both within the self and within the community. On the view I urge, which draws on the work of neopragmatist Richard Rorty and Chicana feminist Gloria Anzaldua, divisions within the self and between citizens are not merely problems always to be overcome, but potential resources for creating a stronger, more inclusive democracy.

Researchers recently demonstrated a strong direct relationship between judgments about what a person knows and judgments about how a person should act. But it remains unknown whether actionability judgments cause knowledge judgments, or knowledge judgments cause actionability judgments. This paper uses causal modeling to help answer this question. Across two experiments, we found evidence that actionability judgments cause knowledge judgments.

The term “Gettier Case” is a technical term frequently applied to a wide array of thought experiments in contemporary epistemology. What do these cases have in common? It is said that they all involve a justified true belief which, intuitively, is not knowledge, due to a form of luck called “Gettiering.” While this very broad characterization suffices for some purposes, it masks radical diversity. We argue that the extent of this diversity merits abandoning the notion of a “Gettier case” in (...) a favour of more finely grained terminology. We propose such terminology, and use it to effectively sort the myriad Gettier cases from the theoretical literature in a way that charts deep fault lines in ordinary judgments about knowledge.

People suffering from severe monothematic delusions, such as Capgras, Fregoli, or Cotard patients, regularly assert extraordinary and unlikely things. For example, some say that their loved ones have been replaced by impostors. A popular view in philosophy and cognitive science is that such monothematic delusions aren't beliefs because they don't guide behaviour and affect in the way that beliefs do. Or, if they are beliefs, they are somehow anomalous, atypical, or marginal beliefs. We present evidence from five studies that folk (...) psychology unambiguously views monothematic delusions as stereotypical beliefs. This calls into question widespread assumptions in the professional literature about belief's stereotypical functional profile. We also show that folk psychology views delusional patients as holding contradictory beliefs. And we show that frequent assertion is a powerful cue to belief ascription, more powerful than even a robust and consistent track record of non-verbal behaviour. (shrink)
