Dark matter is a fundamental component of the standard cosmological model, but in spite of four decades of increasingly sensitive searches, no-one has yet detected a single dark-matter particle in the laboratory. An alternative cosmological paradigm exists: MOND (Modified Newtonian Dynamics). Observations explained in the standard model by postulating dark matter are explained in MOND by proposing a modification of Newton's laws of motion. Both MOND and the standard model have had successes and failures – but only MOND has repeatedly (...) predicted observational facts in advance of their discovery. In this volume, David Merritt outlines why such predictions are considered by many philosophers of science to be the 'gold standard' when it comes to judging a theory's validity. In a world where the standard model receives most attention, the author applies criteria from the philosophy of science to assess, in a systematic way, the viability of this alternative cosmological paradigm.

In this paper I examine and reply to a deflationary challenge brought against virtue ethics. The challenge comes from critics who are impressed by recent psychological evidence suggesting that much of what we take to be virtuous conduct is in fact elicited by narrowly specific social settings, as opposed to being the manifestation of robust individual character. In answer to the challenge, I suggest a conception of virtue that openly acknowledges the likelihood of its deep, ongoing dependence upon particular social (...) relationships and settings. I argue that holding this conception will indeed cause problems for some important strands of thought in virtue ethics, most notably in the tradition of Aristotle's Nicomachean Ethics. But an approach to virtue ethics modeled on David Hume's treatment of virtue and character in A Treatise of Human Nature promises to escape these problems. (shrink)

For Kant, ‘reflection’ is a technical term with a range of senses. I focus here on the senses of reflection that come to light in Kant's account of logic, and then bring the results to bear on the distinction between ‘logical’ and ‘transcendental’ reflection that surfaces in the Amphiboly chapter of the Critique of Pure Reason. Although recent commentary has followed similar cues, I suggest that it labours under a blind spot, as it neglects Kant's distinction between ‘pure’ and ‘applied’ (...) general logic. The foundational text of existing interpretations is a passage in Logik Jäsche that appears to attribute to Kant the view that reflection is a mental operation involved in the generation of concepts from non-conceptual materials. I argue against the received view by attending to Kant's division between ‘pure’ and ‘applied’ general logic, identifying senses of reflection proper to each, and showing that none accords well with the received view. Finally, to take account of Kant's notio.. (shrink)

This study investigates how business leaders dynamically narrate their aspirational ethical leadership identities. In doing so, it furthers understanding of ethical leadership as a process situated in time and place. The analysis focuses on the discursive strategies used to narrate identity and ethics by ethnic Chinese business leaders in Indonesia after their conversion to Pentecostal–charismatic Christianity. By exploring the use of metaphor, our study shows how these business leaders discursively deconstruct their ‘old’ identities and construct their ‘new’ aspirational identities as (...) ethical leaders. This leads to the following contributions. First, we show that ethical leadership is constructed in identity talk as the business leaders actively narrate aspirational identities. Second, the identity narratives of the business leaders suggest that ethical leadership is a context-bound and situated claim vis-à-vis unethical practice. Third, we propose a conceptual template, identifying processes of realisation and inspiration followed by significant shifts in understanding, for the study of aspirational ethical leadership.

There can be no doubt that Kant thought we should be reflective: we ought to care to make up our own minds about how things are and what is worth doing. Philosophical objections to the Kantian reflective ideal have centred on concerns about the excessive control that the reflective person is supposed to exert over her own mental life, and Kantians who feel the force of these objections have recently drawn attention to Kant’s conception of moral virtue as it is (...) developed in his later work, chiefly the Metaphysics of Morals. Melissa Merritt’s book is a distinctive contribution to this recent turn to virtue in Kant scholarship. Merritt argues that we need a clearer, and textually more comprehensive, account of what reflection is, in order not only to understand Kant’s account of virtue, but also to appreciate how it effectively rebuts long-standing objections to the Kantian reflective ideal.

I argue that some important elements of the current cosmological model are 'conventionalist’ in the sense defined by Karl Popper. These elements include dark matter and dark energy; both are auxiliary hypotheses that were invoked in response to observations that falsified the standard model as it existed at the time.

Emotions might contribute to our being rational cognitive agents. Anxiety – and more specifically epistemic anxiety – provides an especially interesting case study into the role of emotion for adaptive cognition. In this paper, I aim at clarifying the epistemic contribution of anxiety, and the role that ill-calibrated anxiety might play in maladaptive epistemic activities which can be observed in psychopathology. In particular, I argue that this emotion contributes to our ability to adapt our cognitive efforts to how we represent (...) the practical factors relevant to the task at hand, by sig- naling the need for increased cognitive processing and evidence gathering in high- stakes situations. I hypothesize that dysfunctional or ill-calibrated epistemic anxiety might play an important role in the motivation driving persons with obsessive- compulsive disorder (OCD) to invest high amounts of cognitive resources into the resolution of apparently simple and innocuous questions. As I argue, OCD might be conceived as a case in which epistemic anxiety is inappropriately elicited, represent- ing these as high-stakes questions, and inadequately signaling a need for cognition. In this paper, I thus make use of the concept of (epistemic) anxiety as developed in the philosophy of emotion and in epistemology, to propose an account of the role of anxiety in the pathological doubt that is central to obsessive-compulsive disorder.

Why did Kant write the Critique of Judgment, and why did he say that his analysis of the judgment of taste — his technical term for our enjoyment of beauty — is the most important part of it? Kant claims that his analysis of taste “reveals a property of our faculty of cognition that without this analysis would have remained unknown” (KU §8, 5:213). The clue lies in Kant’s view that while taste is an aesthetic, and non-cognitive, mode of judgment, (...) it nevertheless involves the “free play” of cognitive capacities that is pleasurable in some way that ordinary cognitive business is not. My thesis is that the judgment of taste reveals a pleasure that is not usually apparent when we understand something in particular, but which is nevertheless proper to the activity of understanding as such. This matters, I argue, because in this way the judgment of taste points to a standard of cognitive virtue. (shrink)

I reconsider the relation between love and respect in Kantian ethics, taking as my guide Iris Murdoch's view of love as the fundamental moral attitude and a kind of attention to individuals. It is widely supposed that Kantian ethics disregards individuals, since we don't respect individuals but the universal quality of personhood they instantiate. We need not draw this conclusion if we recognise that Kant and Murdoch share a view about the centrality of love to virtue. We can then see (...) that respect in the virtuous person cannot be blind to the individual, as critics of Kantian ethics contend. My approach contrasts recent efforts to assimilate Kantian respect to Murdochian love, which overlook Murdoch's distinctive claims about the singularity of moral activity. This idea is not as un-Kantian as it seems, and it should inform any Kantian ethics that aims to address the charge about individuals. (shrink)

“Everyone has a price at which he sells himself”: Immanuel Kant quotes this remark in the 1793 _Religion within the Bounds of Reason Alone_, attributing it to “a member of English Parliament”. I argue, however, that the context of the quotation in the _Religion_ alludes to the arresting pedagogical practices of the Stoic philosopher Epictetus, who famously said that “different people sell themselves at different prices” (Discourses 1.2). I argue that there are two sides of Epictetus’s pedagogical strategies: a jolting (...) side meant to expose self-deception and practical inconsistency; and an uplifting side meant to arouse the resources by which it is possible to progress towards virtue — specifically, our sense of kinship with the divine insofar as we are rational. I argue that Kant develops a conception of self-respect in later practical works that plausibly draws on Epictetus, and his distinctive version of the traditional Stoic account of rational agency.

What does it mean to be a good thinker? Which virtues work together in someone who possesses good intellectual character? Although recent research on virtues has highlighted the benefits of individual intellectual virtues, being an excellent thinker is likely a function of possessing multiple intellectual virtues. Specifically, a good thinker would both recognize one’s intellectual shortcomings and possess an eagerness to learn driven by virtues such as love of knowledge, curiosity, and open-mindedness. Good intellectual character may only successfully manifest when (...) individuals possess not just one or a few intellectual virtues, but a larger set of such virtues to different degrees. However, little is currently known about what combination of virtues are necessary for good thinking. We argue that it is important to identify and clarify the nature of the good thinker and outline a profile methodology for achieving this goal. This approach characterizes the good thinker in terms of a profile of multiple intellectual virtues. Understanding this profile can allow greater insight into the extent to which people possess such a profile, and the potential for societal benefits of educating for these qualities. (shrink)

How does doubt come about? What are the mechanisms responsible for our inclinations to reassess propositions and collect further evidence to support or reject them? In this paper, I approach this question by focusing on what might be considered a distorting mirror of unreasonable doubt, namely the pathological doubt of patients with obsessive–compulsive disorder (OCD). Individuals with OCD exhibit a form of persistent doubting, indecisiveness, and over-cautiousness at pathological levels (Rasmussen and Eisen in Psychiatr Clin 15(4):743–758, 1992; Reed in Obsessional (...) experience and compulsive behaviour: a cognitive-structural approach, Academic Press, Cambridge, 1985; Tolin et al. in Cogn Ther Res 27(6):657–669, 2003). I argue that the failure in OCD is of an affective nature, involving both excessive epistemic anxiety and hyperactive feelings of uncertainty. I further argue that our adaptive disposition to inquire about the right matters—that is, about propositions which are both epistemically risky and imply harmful possibilities—might depend on these affective mechanisms.

A crucial feature of Kant's critical-period writing on the sublime is its grounding in moral psychology. Whereas in the pre-critical writings, the sublime is viewed as an inherently exhausting state of mind, in the critical-period writings it is presented as one that gains strength the more it is sustained. I account for this in terms of Kantian moral psychology, and explain that, for Kant, sound moral disposition is conceived as a sublime state of mind.

My project is to reconsider the Kantian conception of practical reason. Some Kantians think that practical reasoning must be more active than theoretical reasoning, on the putative grounds that such reasoning need not contend with what is there anyway, independently of its exercise. Behind that claim stands the thesis that practical reason is essentially efficacious. I accept the efficacy principle, but deny that it underwrites this inference about practical reason. My inquiry takes place against the background of recent Kantian metaethical (...) debate — each side of which, I argue, correctly points to issues that need to be jointly accommodated in the Kantian account of practical reason. The constructivist points to the essential efficacy of practical reason, while the realist claims that any genuinely cognitive exercise of practical reason owes allegiance to what is there anyway, independently of its exercise. I argue that a Kantian account of respect for persons (“recognition respect”) suggests how the two claims might be jointly accommodated. The result is an empirical moral realism that is itself neutral on the received Kantian metaethical debate. (shrink)

C’est en tant que catégorie de l’entendement que Durkheim aborde le temps. Restituer son approche du temps ainsi que celle de ses disciples, en particulier Henri Hubert, conduit à interroger les fondements de sa sociologie de la connaissance. Le sociomorphisme, dynamique structurante des représentations collectives, constitue la principale intuition de la sociologie durkheimienne de la connaissance. Après avoir rendu compte des acceptions multiples de ce concept, nous montrerons qu’il est inopérant pour une partie importante des catégories dont Durkheim prétend expliquer (...) la genèse, en particulier celle du temps. Cette investigation de la pensée du fondateur conduira ainsi à une remise en cause de sa pertinence globale. L’instabilité conceptuelle de la notion de représentations collectives, la dualité du psychisme humain ainsi que le rôle prépondérant accordé par Durkheim à l’effervescence sociale dans sa théorie du sacré constitueront les lieux de convergence critique de cet article.Time is approached by Durkheim as a category of understanding. Reconstructing this approach, like that of his disciples, in particular Henri Hubert, results in questioning the bases of his sociology of knowledge. Sociomorphism, as a structuring dynamics of collective representations, constitutes the main intuition of Durkheim’s sociology of knowledge. After outlining the various meanings of this concept, we show that it proves ineffectual for an important part of the categories whose genesis Durkheim claims to explain – in particular that of time. This investigation of Durkheim’s thought leads to a general questioning of its relevance. The conceptual instability of collective representations, the duality of human psyche, as well as the leading role Durkheim attached to social effervescence in his thesis of the sacred, constitute the knot of critical convergence of this article.

We have investigated the emotional profile of dreams and the relationship between dream emotion and cognition using a form that specifically asked subjects to identify emotions within their dreams. Two hundred dream reports were collected from 20 subjects, each of whom produced 10 reports. Compared to previous studies, our method yielded a 10-fold increase in the amount of emotion reported. Anxiety/fear was reported most frequently, followed, in order, by joy/elation, anger, sadness, shame/guilt, and, least frequently, affection/eroticism. Unexpectedly, there was no (...) significant difference in the profiles of emotion reported by men and women. When the reports were scored for bizarreness, a significant correlation was found between the occurrence of bizarreness and major shifts in emotion. These results support the conclusion that dreaming is a mental state whose general emotional features are widely shared across individuals and strongly linked to cognitive features within individual dreams.

For Kant, the ideal of enlightenment is most fundamentally expressed as a self-developed soundness of judgment. But what does this mean when the judgment at issue is practical, i.e., concerns the good to be brought about through action? I argue that the moral context places special demands on the ideal of enlightenment. This is revealed through an interpretation of Kant’s prescription for moral pedagogy in the Critique of Practical Reason. The goal of the pedagogy is to cultivate the moral disposition, (...) and the method consists of training in judgment. Unfortunately, Kant seems to wind up somewhere short of this goal, leaving the young person with only an idle wish for a properly cultivated moral disposition. In this paper, I argue that when we address the special issues that arise when the enlightenment ideal is brought to bear on practical judgment — issues that stem from the intrinsic connection between practical judgment and agency — we will see that there is no lacuna in Kant’s account.

It is widely assumed that Kant’s moral psychology draws from the dualist tradition of Plato and Aristotle, which takes there to be distinct rational and non-rational parts of the soul. My aim is to challenge the air of obviousness that psychological dualism enjoys in neo-Kantian moral psychology, specifically in regard to Tamar Schapiro’s account of the nature of inclination. I argue that Kant’s own account of inclination instead provides evidence of his commitment to psychological monism, the idea that the mentality (...) of an adult human being is rational through and through. I first consider Schapiro’s “intuitions” in favour of dualism: inclination must have a non-rational source, she contends, because they assail us unbidden and are not immediately responsive to volition, and because we are not responsible simply for having inclinations (only for acting on them). I explain how a monistic account of the nature of inclination can accommodate the first two points, and explain why the third neither is a point a Kantian can accept, nor is its denial the affront to common sense that Schapiro supposes. Then I turn to Schapiro’s aim to conceive of reflection as non-rational and thus independent of justificatory thought, and yet such as to induce rational reflection. I argue that it remains mysterious how inclination, on her account, could be resourced to play this role; and with that criticism in mind, I conclude by making a positive case for Kant’s conceiving of inclination in monistic terms, as an expression of rational mindedness.

This Element considers Kant's account of the sublime in the context of his predecessors both in the Anglophone and German rationalist traditions. Since Kant says with evident endorsement that 'we call sublime that which is absolutely great' and nothing in nature can in fact be absolutely great, Kant concludes that strictly speaking what is sublime can only be the human calling to perfect our rational capacity according to the standard of virtue that is thought through the moral law. The Element (...) takes account of the difference between respect and admiration as the two main varieties of sublime feeling, and concludes by considering the role of Stoicism in Kant's account of the sublime, particularly through the channel of Seneca.

Kant’s account of “the radical evil in human nature” in the 1793 Religion within the Bounds of Reason Alone is typically interpreted as a reworking of the Augustinian doctrine of original sin. But Kant doesn’t talk about Augustine explicitly there, and if he is rehabilitating the doctrine of original sin, the result is not obviously Augustinian. Instead Kant talks about Stoic ethics in a pair of passages on either end of his account of radical evil, and leaves other clues that (...) his argument is a reworking of an old Stoic problem. “Radical evil” refers to the idea that our moral condition is — by default and yet by our own deed — bad or corrupt; and that this corruption is the root (radix) of human badness in all its variety, ubiquity, and sheer ordinariness. Kant takes as his premise a version of the Stoic idea that nature gives us “uncorrupted starting points” (Diogenes Laertius 7.89). What sense can be made of the origin of human badness, given such a premise? Kant’s account of radical evil is an answer to this old Stoic problem, which requires a conception of freedom that is not available in his Stoic sources. (shrink)

This chapter argues that Kant’s aesthetic theory of the sublime has particular relevance for his ethics of virtue. Kant contends that our readiness to revel in natural sublimity depends upon a background commitment to moral ends. Further lessons about the emotional register of the sublime allow us to understand how Kant can plausibly contend that the temperament of virtue is both sublime and joyous at the same time.

Paul Feyerabend argued that theories can be faced with experimental anomalies whose refuting character can only be recognized by developing alternatives to the theory. The alternate theory must explain the experimental results without contrivance and it must also be supported by independent evidence. I show that the situation described by Feyerabend arises again and again in experiments or observations that test the postulates in the standard cosmological model relating to dark matter. The alternate theory is Milgrom’s modified dynamics. I discuss (...) three examples: the failure to detect dark-matter particles in laboratory experiments; the lack of evidence for dark-matter sub-haloes and the dwarf galaxies that are postulated to inhabit them; and the failure to confirm the predicted orbital decay of Milky Way satellite galaxies and other systems due to dynamical friction against the dark matter. In each case, Feyerabend’s criterion directs us to interpret the experimental or observational results as an indirect refutation of the standard cosmological model in favor of Milgrom’s theory.

In an intriguing but neglected passage in the Transcendental Deduction, Kant appears to link the synthetic activity of the understanding in experience with the phenomenon of attention (B156-7n). In this paper, we take up this hint, and draw upon Kant's remarks about attention in the Anthropology to shed light on the vexed question of what, exactly, the understanding's role in experience is for Kant. We argue that reading Kant's claims about synthesis in this light allows us to combine two aspects (...) of Kant's views that many commentators have thought are in tension with one another: on the one hand, Kant's apparent commitment to naïve realism about perception and, on the other, his apparent commitment to the necessity of synthetic activity by the understanding for any kind of cognitive contact with external objects.

The paper argues that existing interpretations of Kant's Critique of Pure Reason as an "analysis of experience" (e.g., those of Kitcher and Strawson) fail because they do not properly appreciate the method of the work. The author argues that the Critique provides an analysis of the faculty of reason, and counts as an analysis of experience only in a derivative sense.

Existing interpretations of Kant’s appeal to the spontaneity of the mind focus almost exclusively on the discussion of pure apperception in the Transcendental Deduction. The risk of such a strategy lies in the considerable degree of abstraction at which the argument of the Deduction is carried out: existing interpretations fail to reconnect adequately with any ground-level perspective on our cognitive lives. This paper works in the opposite direction. Drawing on Kant’s suggestion that the most basic picture we can have of (...) our cognitive capacity already makes reference to its state of excellence, or health (“sound understanding”), I set out by assembling Kant’s normative ground-level view of our cognitive lives, and then search for the fundamental condition of its possibility. This leads me to Kant’s conception of reflection as a normative requirement of judgment. Through examination of Kant’s remarks on reflection, I connect Kant’s preoccupation with the enlightenment ideal of originality (thinking for oneself) with his central appeal to the spontaneity of the mind.

Alix Cohen argues that the function of feeling in Kantian psychology is to appraise and orient activity. Thus she sees feeling and agency as importantly connected by Kant’s lights. I endorse this broader claim, but argue that feeling, on her account, cannot do the work of orientation that she assigns to it.

This article responds to Professor Romano’s piece in this issue. It concerns our ongoing debate with regard to the desirability of permitting issuers to choose the securities regulation regime by which they are bound. Romano favors issuer choice, arguing that it would result in jurisdictional competition to offer issuers share value maximizing regulations. I, in contrast, believe that abandoning the current mandatory system of federal securities disclosure would likely lower, not increase, U.S. welfare. Each issuer, I argue, would select a (...) regime requiring a level of disclosure less than is socially optimal because its private costs of disclosure would be greater than the social costs of such disclosure. Professor Romano and I agree on most of the basic analytic building blocks for deciding whether issuer choice is a desirable reform: belief in analyzing the problem in terms of the broadly accepted principles of modern financial economics; recognition that disclosure has costs as well as benefits; and acknowledgment that incentives exist for issuers to provide at least some disclosure. We nevertheless reach the opposite conclusion on the desirability of issuer choice. To start, Romano believes that issuers’ private costs of disclosure will not generally be greater than the social costs of such disclosure, whereas I show they will be. Romano argues as well that this is a special case in which any divergence of private and social costs that does exist will not lead to a market failure, at least one possibly correctable by public regulation. I show her argument to be unpersuasive. Finally, Romano interprets the existing empirical evidence as proving mandatory disclosure’s lack of social value, while I show that the evidence in fact does not point in either direction. Where, as here, the theoretical case for the existence of a market failure is strong and the current program for dealing with it is widely admired, the advocate of change should have the burden of proof. Professor Romano has not met this burden. If she is serious about advancing her proposal for issuer choice, she needs to show that despite the market failure inherent in issuer choice, there is inevitably an even greater failure in the regulatory response. Absent such a showing, mandatory disclosure should be retained. (shrink)

Dark matter has never been detected, yet it is a key part of the dominant theory of cosmology. An alternative theory, MOND, is empirically equivalent and more successful at making predictions. But the fact that it has no place for the existence of dark matter is a problem for scientific realists who see science as building on past theories.
