Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin (...) retain an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

To find the neural substrates of consciousness, researchers compare subjects’ neural activity when they are aware of stimuli against neural activity when they are not aware. Ideally, to guarantee that the neural substrates of consciousness—and nothing but the neural substrates of consciousness—are isolated, the only difference between these two contrast conditions should be conscious awareness. Nevertheless, in practice, it is quite challenging to eliminate confounds and irrelevant differences between conscious and unconscious conditions. In particular, there is an often-neglected confound that (...) is crucial to eliminate from neuroimaging studies: task performance. Unless subjects’ task performance is matched (and hence perceptual signal processing is matched), researchers risk finding the neural correlates of perception, rather than conscious perception. Here, we discuss the theoretical motivations for the performance matching framework and review empirical demonstrations of, and theoretical inferences derived from, obtaining differences in consciousness while controlling for task performance. We summarize signal detection theoretic modeling frameworks that explain how it is that we can derive performance-matched differences in consciousness without the effect being trivially driven by differences in criterion setting, and also provide principles for designing experimental paradigms that yield performance-matched differences in awareness. Finally, we address potential technical and theoretical issues that stem from matching performance across conditions of awareness, and we introduce the notion of “triangulation” for designing comprehensive experimental sets that can better reveal the neural substrates of consciousness.

When visual attention is directed away from a stimulus, neural processing is weak and strength and precision of sensory data decreases. From a computational perspective, in such situations observers should give more weight to prior expectations in order to behave optimally during a discrimination task. Here we test a signal detection theoretic model that counter-intuitively predicts subjects will do just the opposite in a discrimination task with two stimuli, one attended and one unattended: when subjects are probed to discriminate the (...) unattended stimulus, they rely less on prior information about the probed stimulus’ identity. The model is in part inspired by recent findings that attention reduces trial-by-trial variability of the neuronal population response and that they use a common criterion for attended and unattended trials. In five different visual discrimination experiments, when attention was directed away from the target stimulus, subjects did not adjust their response bias in reaction to a change in stimulus presentation frequency despite being fully informed and despite the presence of performance feedback and monetary and social incentives. This indicates that subjects did not rely more on the priors under conditions of inattention as would be predicted by a Bayes-optimal observer model. These results inform and constrain future models of Bayesian inference in the human brain. (shrink)

Courts play a key role in deciding on public health controversies, but the legitimacy of judicial intervention remains highly controversial. In this article I suggest that we need to carefully distinguish between different reasons for persistent disagreement in the domain of public health. Adjudicating between public health controversies rooted in factual disagreements allows us to investigate more closely the epistemic capacities of the judicial process. While the critics typically point out the lack of appropriate expertise of judges—in particular with respect (...) to health and public health—we should not move too fast in inferring from this a generalized competence problem. This article offers four reasons for vindicating the importance of judicial intervention in factual disagreements: the relative independence of judges from the political establishment, the judicial commitment to evidence, the specific nature of judicial reasoning and an additional voice for the people in the policy-making process.

In this paper, I raise the problem of dealing with counterpossible conditionals for theories of subject matter. I argue that existing accounts of subject matter need to be revised and extended to be able to a) provide reasonable (potentially non-degenerate) verdicts about what counterpossibles are about, b) explain the intuition that counterpossibles are in some sense about what would happen if the antecedent were true, and c) explain in what sense counterpossibles can be about individuals. I sketch how one could (...) extend atom-based and way-based theories of subject matters to handle the problem. Then, I raise the problem that it might be desirable for a theory of subject matter to prevent the inference that certain counterpossibles are about the kinds of things that they seem to mention.

Se discuten dos argumentos del diálogo Protágoras sobre la relación entre las virtudes individuales. En primer lugar se defiende -frente a Terry Penner- la tesis de Vlastos de que cuando Sócrates dice que "la justicia es justa", "la justicia es piadosa", etc., está destacando la mutua implicación entre las virtudes, y no su identidad; y se formula una hipótesis para explicar la razón de tal reciprocidad. En segundo lugar, se examina el argumento de que, puesto que la insensatez se opone (...) tanto a la moderación como a la sabiduría, y un término contrario no puede tener más de un contrario, moderación y sabiduría serían "una sola cosa". Se asevera que Platón quiere que rechacemos esta última conclusión, basada en el fondo en la idea de que las distintas virtudes se relacionan entre sí como las partes de un mismo rostro. Se concluye que los argumentos analizados no implican realmente la idea contraintuitiva de la identifi cación mutua de las virtudes.Two arguments from the Protagoras on the unity of the virtues are here dwelt with. First, it is claimed - with G. Vlastos and contra T. Penner - that when Socrates says that “justice is just”, “justice is pious”, etc. he wants to highlight the reciprocity of the individual virtues, not their mutual identity . Second, it is argued that Plato does not really want us to infer from folly’s opposition to both temperance and wisdom the need to identify these two virtues . He is only drawing our attention to their close relationship. This is enough to reject the hypothesis initially defended by Protagoras, i.e. that the different virtues relate to each other as the parts of a face. I conclude that the two aforesaid arguments do not really support the mutual identity of the virtues. (shrink)

The authors explore the interfaces between different dimensions of moral cognition, bridging economic, Bayesian and reinforcement learning perspectives. The human aversion to harming others cuts across these different interfaces, influencing decisions, judgments, and inferences about morality.

Just as humans can draw conclusions responsibly or irresponsibly, so too can computers. Machine learning systems that have been trained on data sets that include irresponsible judgments are likely to yield irresponsible predictions as outputs. In this paper I focus on a particular kind of inference a computer system might make: identification of the intentions with which a person acted on the basis of photographic evidence. Such inferences are liable to be morally objectionable, because of a way in which (...) they are presumptuous. After elaborating this moral concern, I explore the possibility that carefully procuring the training data for image recognition systems could ensure that the systems avoid the problem. The lesson of this paper extends beyond just the particular case of image recognition systems and the challenge of responsibly identifying a person’s intentions. Reflection on this particular case demonstrates the importance (as well as the difficulty) of evaluating machine learning systems and their training data from the standpoint of moral considerations that are not encompassed by ordinary assessments of predictive accuracy.

Throughout the Covid-19 pandemic, people have been eager to learn what factors, and especially what public health policies, cause infection rates to wax and wane. But figuring out conclusively what causes what is difficult in complex systems with nonlinear dynamics, such as pandemics. We review some of the challenges that scientists have faced in answering quantitative causal questions during the Covid-19 pandemic, and suggest that these challenges are a reason to augment the moral dimension of conversations about causal (...) class='Hi'>inference. We take a lesson from Martha Nussbaum—who cautions us not to think we have just one question on our hands when we have at least two—and apply it to modeling for causal inference in the context of cost-benefit analysis.

Sarah McGrath argues that moral perception has an advantage over its rivals in its ability to explain ordinary moral knowledge. I disagree. After clarifying what the moral perceptualist is and is not committed to, I argue that rival views are both more numerous and more plausible than McGrath suggests: specifically, I argue that inferentialism can be defended against McGrath’s objections; if her arguments against inferentialism succeed, we should accept a different rival that she neglects, intuitionism; and, reductive (...) epistemologists can appeal to non-naturalist commitments to avoid McGrath’s counterexamples.

CHANGE SLIDE Go through outline of talk CHANGE SLIDE It is my sincerest hope that if there is one thing that people take away from Moral Fictionalism, it is the recognition that standard noncognitivism involves a syndrome of three, logically distinct claims. Standard noncognitivists claim that moral judgment is not belief or any other cognitive attitude but is, rather, a noncognitive attitude more akin to desire; that this noncognitive attitude is expressed by our public moral utterances; and, (...) hence, that our public moral utterances lack a distinctively moral subject matter and so are not answerable to the moral facts. Notice, however, that these are logically distinct claimsthe rst is a psychological claim, the second and third, positive and negative semantic claims, respectively. We can regiment the familiar technical vocabulary as follow: CHANGE.. (shrink)

The article is devoted to an analysis of David Hume’s position on God’s benevolence in his Dialogues Concerning Natural Religion. The focal point is the problem of inference and the accompanying arguments concerning the relations between good and evil, as well as the four circumstances in which evil enters the world. In the conclusion, I discuss the hypothesis of moral indifference as Hume’s skeptical voice in the debate on the possibility of inferring the moral attributes of God (...) on the basis of experience.

The question of corporate moral responsibility – whether corporate bodies can be held morally responsible for their actions – has been debated by a number of writers since the 1970s. This discussion is intended to add to that debate, and focuses for that purpose on our understanding of the organisation. Though the integrity of the organisation has been called into question by the postmodern view of organisations, that view does not necessarily rule out the attribution of corporate agency, any (...) more than the postmodern view of the person rules out the attribution of individual agency. The postmodern view is opposed to a reifying, metaphysical view of corporate agency, but a semantic view of corporate agency would seem to sit more comfortably with it. A bigger problem for the idea of corporate moral responsibility arises from the fact that in Kantian terms organisations are not ends in themselves. In that sense they are not like persons, and this must limit their autonomy, and their responsibility. This aspect of organisations also limits their punishability. For these reasons corporate moral responsibility must be seen as more limited than the responsibility of persons. (shrink)

The incidence and moral implications of cheating depend on how it is defined and measured. Research that defines and operationalizes cheating as an inventory of acts, that is, “cheating in any form,” has often fueled concern that cheating is reaching “epidemic proportions.” Such inventory measures appear, however, to conflate moral and administrative conceptions of the problem. Inasmuch as the immorality of behavior is a function of moral judgment, academic misconduct is immoral only when it is intentional, and (...) the greatest moral weight should be ascribed to violations that students judge to be the most “serious.”.

We argue that stereotypes associated with concepts like he-said–she-said, conspiracy theory, sexual harassment, and those expressed by paradigmatic slurs provide “normative inference tickets”: conceptual permissions to automatic, largely unreflective normative conclusions. These “mental shortcuts” are underwritten by associated stereotypes. Because stereotypes admit of exceptions, normative inference tickets are highly flexible and productive, but also liable to create serious epistemic and moral harms. Epistemically, many are unreliable, yielding false beliefs which resist counterexample; morally, many perpetuate bigotry and oppression. (...) Still, some normative inference tickets, like some activated by sexual harassment, constitute genuine moral and hermeneutical advances. For example, our framework helps explain Miranda Fricker’s notion of “hermeneutical lacunae”: what early victims of “sexual harassment” — as well as their harassers — lacked before the term was coined was a communal normative inference ticket — one that could take us, collectively, from “this is happening” to “this is wrong.”.

This paper defends a moderate intuitionism by extending a version of that view previously put forward and responding to some significant objections to it that have been posed in recent years. The notion of intuition is clarified, and various kinds of intuition are distinguished and interconnected. These include doxastic intuitions and intuitive seemings. The concept of inference is also clarified. In that light, the possibility of non-inferential intuitive justification is explained in relation to both singular moral judgments, which (...) intuitionists do not take to be self-evident, and basic moral principles, which they typically do take to be self-evident in a sense explicated in the paper. This explanation is accomplished in part by drawing some analogies between moral and perceptual judgments in the light of a developmental conception of knowledge. The final section of the paper presents a partial account of rational disagreement and indicates how the kind of intuitionist view defended can allow for rational disagreement between apparent epistemic peers.

Working toward a phenomenological account of depression, this article suggests that the relevant level of analysis is that of experiential immediacy based on intersubjectivity. The argument focuses on the experience of one boy and one girl who participated in the study Southwest Youth and the Experience of Psychiatric Treatment (SWYEPT), in which we followed the experience of adolescent psychiatric inpatients and their families over the course of a year. I emphasize the role of language as a form of disclosure and (...) empathy in the interview setting in elaborating a set of criteria for inferring immediacy from interview data, and point to how illness experience is bound up with domains of the life-world such as relationships, religion, morality, reflexivity, identity, and treatment.

In this paper, I defend what I call the ‘Inference Principle’. This principle holds that if an agent obtains some information legitimately, then the agent can make any inference she wants based on the information, without violating anyone’s right to privacy. This principle is interesting for at least three reasons. First, it constitutes a novel answer to the timely question of whether the widespread use of ‘data analytics’ to infer personal information about individuals is morally permissible. Second, it (...) contradicts what seems to be a common view of inferences’ ability to violate privacy rights. Third, it offers an account of the theoretically underdeveloped issue of what duties are engendered by the moral right to privacy with regard to inferred information. (shrink)

The present study examined the role of morality, competence, and attractiveness as perceived from faces in predicting hiring decisions for men and women. Results showed that for both female and male applicants, facial competence significantly predicted the hiring decision directly and indirectly, through the mediation of the overall impression. Decisions concerning female applicants were, however, significantly predicted by multiple dimensions—that is, facial morality, facial competence, and attractiveness—with the mediation of the overall impression. Facial competence was the only significant predictor of (...) impression and, in turn, hiring decision about men. These findings resonate the mottoVirtutem forma decorat, “Beauty adorns virtue,” painted by Leonardo da Vinci on the reverse side of the portrait of Ginevra de’ Benci, and suggest that women’s chances of getting a job are less than those of men whenever they do not show a moralandcompetentandattractive face.

Morality is the effort to guide one’s conduct by reasons, that is, to do what there are the best reasons for doing. From a cognitive perspective, there are many types of moral hypotheses that provide good reasons in practical and moral deliberation and action. They can take the form of principles, rules, prototypes, previous analogical cases, examples, images, feelings, metaphors, narratives, and so on. I will address the central problems of the logical structure of reasons and of inferring (...) reasons taking advantage of the fundamental distinction, suggested by Searle, between internal and external reasons. What, then, is the role of internal reasons? The answer is that they serve, in a certain way, to mediate between external and internal obligations by connecting them both logically and causally in practical and moral cognition and illustrating the relative importance of abductive cognition. Internal reasons might be based on a desire or an intention, for instance, while external reasons may be grounded in external obligations and duties that we may recognize as such. (shrink)

Some claim that moral factors affect the epistemic status of our beliefs. Call this the moral encroachment thesis. It’s been argued that the moral encroachment thesis can explain at least part of the wrongness of racial profiling. The thesis predicts that the high moral stakes in cases of racial profiling make it more difficult for these racist beliefs to be justified or to constitute knowledge. This paper considers a class of racial generalizations that seem to do (...) just the opposite of this. The high moral stakes of the beliefs we infer from these generalizations make it easier rather than harder for these beliefs to be justified or to constitute knowledge. I argue that the existence of this class of cases—cases of “positive profiling”—give us reason to expand our account of moral encroachment in a way that brings it closer to the ideal of pragmatic encroachment that motivates it in the first place.

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against (...) certain theories in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

The past 15 years occasioned an extraordinary blossoming of research into the cognitive and affective mechanisms that support moral judgment and behavior. This growth in our understanding of moral mechanisms overshadowed a crucial and complementary question, however: How are they learned? As this special issue of the journal Cognition attests, a new crop of research into moral learning has now firmly taken root. This new literature draws on recent advances in formal methods developed in other domains, such (...) as Bayesian inference, reinforcement learning and other machine learning techniques. Meanwhile, it also demonstrates how learning and deciding in a social domain—and especially in the moral domain—sometimes involves specialized cognitive systems. We review the contributions to this special issue and situate them within the broader contemporary literature. Our review focuses on how we learn moral values and moral rules, how we learn about personal moral character and relationships, and the philosophical implications of these emerging models. (shrink)

I draw on neurobiological evidence to defend the rationalist thesis that moral judgments are essentially dependent on reasoning, not emotions (conceived as distinct from inference). The neuroscience reveals that moral cognition arises from domain-general capacities in the brain for inferring, in particular, the consequences of an agent’s action, the agent’s intent, and the rules or norms relevant to the context. Although these capacities entangle inference and affect, blurring the reason/emotion dichotomy doesn’t preferentially support sentimentalism. The argument (...) requires careful consideration of the empirical evidence (from neuroimaging to psychopathology) and philosophical analysis of the commitments of rationalism versus sentimentalism in ethics.

Walter Sinnott-Armstrong has developed and progressively refined an argument against moral intuitionism—the view on which some moral beliefs enjoy non-inferential justification. He has stated his argument in a few different forms, but the basic idea is straightforward. To start with, Sinnott-Armstrong highlights facts relevant to the truth of moral beliefs: such beliefs are sometimes biased, influenced by various irrelevant factors, and often subject to disagreement. Given these facts, Sinnott-Armstrong infers that many moral beliefs are false. What (...) then shall we think of our own moral beliefs? Either we have reason to think some of our moral beliefs are reliably formed or we have no such reason. If the latter, our moral beliefs are unjustified. If we have reason to think some moral beliefs are reliably formed, then those beliefs are not non-inferentially justified, because then we’ll have reason to accept something—namely, that they are reliably formed—that entails or supports those beliefs. But then, either way, our moral beliefs are not non-inferentially justified, and so moral intuitionism is false. This paper takes issue with Sinnott-Armstrong’s interesting and widely discussed argument, which we here call the Empirical Defeat Argument (EDA). According to us, the EDA does not defeat moral intuitionism. In section 1, we will set out the argument, briefly reviewing the rationale Sinnott-Armstrong offers for the premises. Then, in section 2, we identify a critical but dubious epistemological assumption concerning the nature of defeat that undergirds the argument. Finally, in section 3, we will defend our challenge to the EDA by answering two objections. (shrink)

Our moral convictions cannot, on the face of it, count in evidence against scientific claims with which they happen to conflict. Moral anti-realists of whatever stripe can explain this easily: science is immune to moral refutation because moral discourse is defective as a trustworthy source of true and objective judgments. Moral realists, they can add, are unable to explain this immunity. After describing how anti-realists might implement this reasoning, the paper argues that the only plausible (...) realist comeback turns on the practical nature of moral reasoning. This comeback, however, places significant constraints on the structure of evidence for moral judgments. These constraints cannot be met by coherentist defenders of reflective-equilibrium methodology or by anyone sympathetic to bottom-up, case-driven foundationalism, including those who claim we have perceptual or perception-like access to moral truths. Unfortunately for realists in these categories, alternative realism-friendly accounts of science’s apparent moral immunity are unpromising. These neither explain nor explain away our unwillingness to infer an is from an ought, as Hume might have put it. Science’s apparent immunity to moral refutation therefore poses a serious problem for any realist unhappy with top-down, theory-driven conceptions of the structure of moral evidence. (shrink)

Certain hypotheses cannot be directly confirmed for theoretical, practical, or moral reasons. For some of these hypotheses, however, there might be a workaround: confirmation based on analogical reasoning. In this paper we take up Dardashti, Hartmann, Thébault, and Winsberg’s (in press) idea of analyzing confirmation based on analogical inference Baysian style. We identify three types of confirmation by analogy and show that Dardashti et al.’s approach can cover two of them. We then highlight possible problems with their model (...) as a general approach to analogical inference and argue that these problems can be avoided by supplementing Bayesian update with Jeffrey conditionalization.

How is moral knowledge possible? This paper defends the anti-Humean thesis that we can acquire moral knowledge by deduction from wholly non-moral premises. According to Hume’s Law, as it has become known, we cannot deduce an ‘ought’ from an ‘is’, since it is “altogether inconceivable how this new relation can be a deduction from others, which are entirely different from it” (Hume, 1739, 3.1.1). This paper explores the prospects for a deductive theory of moral knowledge that (...) rejects Hume’s Law. (shrink)

Current developments in empirical moral psychology have spawned a new perspective on the traditional metaethical question of whether moral judgment is based on reason or emotion. Psychologists and cognitive neuroscientists such as Joshua Greene argue that there is empirical evidence that emotion is essential for one particularly important subclass of moral judgments: so-called ?deontological judgments.? In this paper, I scrutinize this claim and argue that neither the empirical evidence for Greene's dual process-theory of moral judgment nor (...) the normative conclusions it is supposed to yield can be maintained. More specifically, I argue that the evidence from neuroimaging relies on a problematic reverse inference, that the behavioral data are flawed, and that the findings from focal brain damage do not support the model. From a normative point of view, Greene fails to show that we ought to discount the intuitions that give rise to deontological judgments because they respond to morally irrelevant factors: firstly, I show that they do not pick up on the factors Greene deems to be morally irrelevant in the first place, and secondly, I argue that there generally is reason to trust our deontological intuitions.

Do moral properties figure in the best explanatory account of the world? According to a popular realist argument, if they do, then they earn their ontological rights, for only properties that figure in the best explanation of experience are real properties. Although this realist strategy has been widely influential—not just in metaethics, but also in philosophy of mind and philosophy of science—no one has actually made the case that moral realism requires: namely, that moral facts really will (...) figure in the best explanatory picture of the world. This issue may have been neglected in part because the influential dialectic on moral explanations between philosophers Gilbert Harman and Nicholas Sturgeon has focused debate on whether moral facts figure in relevant explanations. Yet as others have noted, explanatory relevance is irrelevant when it comes to realism: after all, according to the popular realist argument, it is inference to the best explanation of experience that is supposed to confer ontological rights. I propose to ask, then, the relevant question about moral explanations: should we think that moral properties will figure in the best explanatory account of the world? (shrink)

This essay investigates the structure and meaning of the Mengzi’s 孟子 analogical inferences in Mengzi 6A7. In this chapter, he argues that just as the perceptual masters allowed the discovery of our senses’ uniform preferences, the sages enabled us to recognize our hearts’ universal preferences for “order and righteousness.” Regarding an unresolved question of how the sages help us understand our hearts’ preferred objects as such, I propose a spectator-based moral artisanship reading as an alternative to an evaluator-focused (...) class='Hi'>moral connoisseurship view: the sages are moral artisans who refine their moral achievements, and people’s uniform approval of their achievements—firmly associated with “order and righteousness”—demonstrates our hearts’ same natural preferences for them. Furthermore, I argue that this chapter’s conclusion—we and the sages are of the same kind with natural moral preferences—implies the necessity of our transition from passive spectators to active moral performers for moral self-cultivation.

Abstract:When people reason on the basis of moral rules, do they suppose that in the absence of a prohibitory rule they are free to act, or do they suppose that morality always requires a justification establishing a permission to act? In this essay we present a series of learning experiments that indicate when learners tend to close their system on the basis of natural liberty and when on the principle of residual prohibition. Those who are taught prohibitory rules tend (...) to infer natural liberty while those taught permission rules tend to infer residual prohibition. In mixed cases, where learners are taught both types of rules, there is some tendency to suppose that natural liberty is the default. Both natural liberty and its denial can be learned; is there a reason to adopt one system of moral rules or the other? We argue that systems of social morality based on a principle of natural liberty have a striking advantage over their competitors: they are well adapted to effectively exploring the constant novel circumstances that arise in open, dynamic, societies.

A prominent view of psychopathic moral reasoning suggests that psychopathic individuals cannot properly distinguish between moral wrongs and other types of wrongs. The present study evaluated this view by examining the extent to which 109 incarcerated offenders with varying degrees of psychopathy could distinguish between moral and conventional transgressions relative to each other and to nonincarcerated healthy controls. Using a modified version of the classic Moral/Conventional Transgressions task that uses a forced-choice format to minimize strategic responding, (...) the present study found that total psychopathy score did not predict performance on the task. Task performance was explained by some individual subfacets of psychopathy and by other variables unrelated to psychopathy, such as IQ. The authors conclude that, contrary to earlier claims, insufficient data exist to infer that psychopathic individuals cannot know what is morally wrong. (shrink)

This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called “experimental philosophical bioethics” (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people’s moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute (...) to substantive ethical questions about what should be done in a given context. What are some of the ways in which this aim has been pursued? In this paper, we employ a case study approach to examine and critically evaluate four strategies from the recent literature by which scholars in bioxphi have leveraged empirical data in the service of normative arguments.

It would seem possible in principle … to reconstruct the ordinary sentential calculus in terms of phrastics only, and then apply it to indicatives and imperatives alike simply by adding the appropriate neustics.… It might be asked how we are to know, given two premisses in different moods, in what mood the conclusion is to be. The problem of the effect upon inferences of the moods of premisses and conclusion has been ignored by logicians who have not looked beyond the (...) indicative mood, … But if, as I do, we regard the entailment-relations of ordinary logic as relations between the phrastics of sentences, the problem becomes pressing.

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and (...) the trolley driver is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)

An ancient but central divide in moral philosophy concerns the nature of opinions about what is morally wrong or what our moralduties are. Some philosophers argue that moral motivation is internal to moral opinions: that moral opinions consist of motivationalstates such as desires or emotions. This has often been seen as athreat to the possibility of rational argument and justification inmorals. Other philosophers argue that moral motivation is external to moral opinion: moral opinions (...) should be seen as beliefs about moral reality, beliefs which may or may not motivate depending onwhether the person holding them cares about moral matters. In this essay it is argued that although the traditional case forthe internalist position fails, the total available evidence andmethodological considerations support an internalist theory formu-lated in terms of a relatively rich psychological model. It is shown how such a theory can explain not only the practical character of moral opinions and their connection to moral emotions but alsophenomena that have been taken to suggest an externalist picture,such as the role of inference, inconsistency, argument and explanations in moral discussion, as well as cases of amoralism and psychological disturbance. In the end, it is concluded that externalistexplanations of the same phenomena are methodologically inferiorfor postulating a more complicated psychology. (shrink)

I characterise moral intuitionism as the methodological claim that one may legitimately appeal to moral judgments in the course of moral reasoning even when those judgments are not supported by inference from other judgments. I describe two patterns of criticism of this method: ‘morally unserious’ criticisms, which hold that ‘morality is bunk’, so appeals to moral intuitions are bunk as well; and ‘morally serious’ criticisms, which hold that morality is not bunk, but that appeals to (...) moral intuition are nonetheless misguided. I consider morally serious criticisms of Kantian and Aristotelian provenance, but defend the intuitionist method from both. (shrink)

Reeder’s article offers a new and intriguing approach to the study of people’s ordinary understanding of freedom and constraint. On this approach, people use information about freedom and constraint as part of a quasi-scientific effort to make accurate inferences about an agent’s motives. Their beliefs about the agent’s motives then affect a wide variety of further psychological processes, including the process whereby they arrive at moral judgments. In illustrating this new approach, Reeder cites an elegant study he conducted a (...) number of years ago (Reeder & Spores, 1983). All subjects were given a vignette about a man who goes with his date to a pizza parlor and happens to come across a box that has been designated for charitable donations. In one condition, the man’s date then requests that he make a donation; in the other, she requests that he steal the money that is already in the box. In both conditions, the man chooses to comply with this request. The key question is how subjects will use his behavior to make inferences about whether he is a morally good or morally bad person. The results revealed a marked difference between conditions. When the man donated to charity, subjects were generally disinclined to conclude that he must have been a morally good person. It is as though they were thinking: ‘He didn’t just do this out of the goodness of his heart. (shrink)

Two long-standing arguments in cognitive science invoke the assumption that holistic inference is computationally infeasible. The first is Fodor’s skeptical argument toward computational modeling of ordinary inductive reasoning. The second advocates modular computational mechanisms of the kind posited by Cosmides, Tooby and Sperber. Based on advances in machine learning related to Bayes nets, as well as investigations into the structure of scientific and ordinary information, I maintain neither argument establishes its architectural conclusion. Similar considerations also undermine Fodor’s decades-long diagnosis (...) of artificial intelligence research as confounded by an inability to circumscribe the amount of information relevant to inferential processes. This diagnosis is particularly inapposite with respect to Bayes nets, since one of their strengths as machine learning systems has been their capacity to reason probabilistically about large data sets whose size overwhelms the capacities of individual human reasoners. A general moral follows from these criticisms: Insights into artificial and human cognitive systems are likely to be cultivated by focusing greater attention on the structure and density of connections among items of information that are available to them.

Despite its many advantages as a metaethical theory, moral expressivism faces difficulties as a semantic theory of the meaning of moral claims, an issue underscored by the notorious Frege-Geach problem. I consider a distinct metaethical view, inferentialism, which like expressivism rejects a representational account of meaning, but unlike expressivism explains meaning in terms of inferential role instead of expressive function. Drawing on Michael Williams’ recent work on inferential theories of meaning, I argue that an appropriate understanding of the (...) pragmatic role of moral discourse—the facilitation of coordinated social behavior—suggests the kind of inferences we should expect terms with this function to license. I offer a sketch of the inferential roles the moral ‘ought’ plays, and argue that if we accept that the relevant inferential roles are meaning-constitutive, we will be in a position to solve the Frege-Geach problem. Such an inferentialist solution has advantages over those forwarded by expressivists such as Blackburn and Gibbard. First, it offers a more straightforward explanation of the meaning of moral terms. It also gives simple answers to at least two semantic worries that have vexed contemporary expressivists—the “problem of permissions” and the commitment to “mentalism”, both of which I argue are problems that don’t get traction with an inferentialist approach. I conclude by considering ways in which this approach can be expanded into a more robust semantic account. (shrink)

I argue that John Dewey’s analysis of imagination enables an account of learning from imaginary cases consistent with Jonathan Dancy’s moral particularism. Moreover, this account provides a more robust account of learning from cases than Dancy’s own. Particularism is the position that there are no, or at most few, true moral principles, and that competent reasoning and judgment do not require them. On a particularist framework, one cannot infer from an imaginary case that because a feature has a (...) particular moral importance there, that it must have that import in an actual case. Instead, for Dancy, cases can yield “reminders,” and a person with a lot of experience (real or imagined) brings a “checklist” of features that can matter to a situation. Using the Nathan-David exchange from 2 Samuel and Martha Nussbaum’s “Steerforth’s Arm” from Love’s Knowledge, I show that this account does not explain all instances of learning from cases. Drawing on recent work on cases, I argue that cases can be educative by serving an exploratory function, probing what one takes to be known and provoking change in the background one uses in evaluating a situation. I then argue that Dewey’s work on imagination in his comments on sympathy and in A Common Faith and Art as Experience enables such a role for cases on a particularist framework. Mark Johnson’s recent work on metaphor further illuminates how Dewey’s account of art can be exploratory. I contend that this account affords an exploratory role for cases consistent with Dancy’s particularism. (shrink)

In the Principles of Philosophy, Descartes explains several observable phenomena showing that they are caused by special arrangements of unobservable microparticles. Despite these microparticles being unobservable, many passages suggest that he was very confident that these explanations were correct. In other passages, however, Descartes points out that these explanations merely hold the status of “suppositions” or “conjectures” that could be wrong. My main goal in this chapter is to clarify this apparent conflict. I argue first that for Descartes it was (...) indeed possible to have knowledge of unobservable particles and structures, and that the possibility of natural explanations being wrong should be understood as these explanations not being absolutely certain, but only morally certain. I use the debate in contemporary philosophy of science between scientific realism and antirealism as a framework to understand how Cartesian explanations work. Especifically, I argue that Cartesian explanations rely on what Ernan McMullin calls retroduction, which is a mode of inference that justifies beliefs in concrete unobservable entities and processes, based on considerations such as simplicity, coherence, etc. This kind of justification is of common use among scientific realists. Thus, another goal of this chapter is to highlight the relevance of Descartes’ ideas about explanation in the contemporary debate on scientific realism. (shrink)
