If people believe that some property is true of all members of a class such as sofas, then they should also believe that the same property is true of all members of a conjunctively defined subset of that class such as uncomfortable handmade sofas. A series of experiments demonstrated a failure to observe this constraint, leading to what is termed the inverse conjunction fallacy. Not only did people often express a belief in the more general statement but not in the (...) more specific, but also when they accepted both beliefs, they were inclined to give greater confidence to the more general. It is argued that this effect underlies a number of other demonstrations of fallacious reasoning, particularly in category-based induction. Alternative accounts of the phenomenon are evaluated, and it is concluded that the effect is best interpreted in terms of intensional reasoning [Tversky, A., & Kahneman, D.. Extensional versus intuitive reasoning: the conjunction fallacy in probability judgment. Psychological Review, 90, 293-315.]. (shrink)

Causal reasoning and game-theoretic reasoning are fundamental topics in artificial intelligence, among many other disciplines: this paper is concerned with their intersection. Despite their importance, a formal framework that supports both these forms of reasoning has, until now, been lacking. We offer a solution in the form of (structural) causal games, which can be seen as extending Pearl's causal hierarchy to the game-theoretic domain, or as extending Koller and Milch's multi-agent influence diagrams to the causal domain. We then consider three (...) key questions: i) How can the (causal) dependencies in games - either between variables, or between strategies - be modelled in a uniform, principled manner? ii) How may causal queries be computed in causal games, and what assumptions does this require? iii) How do causal games compare to existing formalisms? To address question i), we introduce mechanised games, which encode dependencies between agents' decision rules and the distributions governing the game. In response to question ii), we present definitions of predictions, interventions, and counterfactuals, and discuss the assumptions required for each. Regarding question iii), we describe correspondences between causal games and other formalisms, and explain how causal games can be used to answer queries that other causal or game-theoretic models do not support. Finally, we highlight possible applications of causal games, aided by an extensive open-source Python library. (shrink)

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. To (...) avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

In the field of machine consciousness, it has been argued that in order to build human-like conscious machines, we must first have a computational model of qualia. To this end, some have proposed a framework that supports qualia in machines by implementing a model with three computational areas (i.e., the subconceptual, conceptual, and linguistic areas). These abstract mechanisms purportedly enable the assessment of artificial qualia. However, several critics of the machine consciousness project dispute this possibility. For instance, Searle, in his (...) Chinese room objection, argues that however sophisticated a computational system is, it can never exhibit intentionality; thus, would also fail to exhibit consciousness or any of its varieties. This paper argues that the proposed architecture mentioned above answers the problem posed by Searle, at least in part. Specifically, it argues that we could reformulate Searle’s worries in the Chinese room in terms of the three-stage artificial qualia model. And by doing so, we could see that the person doing all the translations in the room could realize the three areas in the proposed framework. Consequently, this demonstrates the actualization of self-consciousness in machines. (shrink)

Within contemporary philosophy of mind, it is taken for granted that externalist accounts of meaning and mental content are, in principle, orthogonal to the matter of whether cognition itself is bound within the biological brain or whether it can constitutively include parts of the world. Accordingly, Clark and Chalmers (1998) distinguish these varieties of externalism as ‘passive’ and ‘active’ respectively. The aim here is to suggest that we should resist the received way of thinking about these dividing lines. With reference (...) to Brandom’s (1994; 2000; 2008) broad semantic inferentialism, we show that a theory of meaning can be at the same time a variety of active externalism. While we grant that supporters of other varieties of content externalism (e.g., Putnam 1975 and Burge 1986) can deny active externalism, this is not an option for semantic inferentialists: On this latter view, the role of the environment (both in its social and natural form) is not ‘passive’ in the sense assumed by the alternative approaches to content externalism.

At the core of Kant’s Critique of Pure Reason was a decisive break with certain fundamental Cartesian assumptions or claims about consciousness and self-consciousness, claims that have nonetheless remained perennially tempting, from a phenomenological perspective, independently of any further questions concerning the metaphysics of mind and its place in nature. The core of this philosophical problem has recently been helpfully exposed and insightfully probed in Dan Zahavi’s book, Self and Other: Exploring Subjectivity, Empathy, and Shame. In these remarks I suggest (...) that Zahavi’s view of what he calls ‘The Experiential Self’ defends precisely the sorts of claims to which a Kantian account of consciousness is fundamentally opposed, and while assessing the overall merits of the two contrasting outlooks is no easy matter, I side with the Kantian view.

My aim in this chapter is to reconstruct Feyerabend’s anti-scientism by comparing it with the similar critiques of one of his main philosophical influences – Ludwig Wittgenstein. I argue that they share a common conception of scientism that gathers around a concern that it erodes a sense of wonder or mystery required for a full appreciation of human existence – a sense that Feyerabend, like Wittgenstein, characterised in terms of the ‘mystical’.

Psychopaths are the bugbears of moral philosophy. They are often used as examples of perfectly rational people who are nonetheless willing to do great moral wrong without regret; hence the disorder has received the epithet “moral insanity” (Pritchard 1835). But whereas philosophers have had a great deal to say about psychopaths’ glaring and often horrifying lack of moral conscience, their aesthetic capacities have received hardly any attention, and are generally assumed to be intact or even enhanced. Popular culture often portrays (...) psychopaths in ways that suggest a great gap between their amorality and their aesthetic sensitivity. In The Silence of the Lambs (Jonathan Demme, 1991), Hannibal Lecter appreciates fine art, fashion, and wine, while he eats his way through his enemies. His real-life counterparts, however, do not demonstrate the same sensitivities. There is no evidence that psychopaths are capable of real aesthetic appreciation, and some evidence that they are not. In this paper, we set out the limited evidence for the psychopath’s deficient aesthetic sensitivity. The best explanations of what the psychopath lacks turn out to implicate abilities that are also thought to be central to moral thought and action: an impaired capacity for empathizing with others and deficient ability to take a disinterested attitude towards things (socalled distance). We endorse the latter explanation. Thinking about what underlies the psychopath’s deficient aesthetic understanding turns out to throw light on a difficult problem: the connection between ethics and aesthetics. (shrink)

This review aims to identify (1) sources of knowledge and (2) important themes of the ethical debate related to surgical alteration of facial features in East Asians. This article integrates narrative and systematic review methods. In March 2014, we searched databases including PubMed, Philosopher’s Index, Web of Science, Sociological Abstracts, and Communication Abstracts using key terms “cosmetic surgery,” “ethnic*,” “ethics,” “Asia*,” and “Western*.” The study included all types of papers written in English that discuss the debate on rhinoplasty and blepharoplasty (...) in East Asians. No limit was put on date of publication. Combining both narrative and systematic review methods, a total of 31 articles were critically appraised on their contribution to ethical reflection founded on the debates regarding the surgical alteration of Asian features. Sources of knowledge were drawn from four main disciplines, including the humanities, medicine or surgery, communications, and economics. Focusing on cosmetic surgery perceived as a westernising practice, the key debate themes included authenticity of identity, interpersonal relationships and socio-economic utility in the context of Asian culture. The study shows how cosmetic surgery of ethnic features plays an important role in understanding female identity in the Asian context. Based on the debate themes authenticity of identity, interpersonal relationships, and socio-economic utility, this article argues that identity should be understood as less individualistic and more as relational and transformational in the Asian context. In addition, this article also proposes to consider cosmetic surgery of Asian features as an interplay of cultural imperialism and cultural nationalism, which can both be a source of social pressure to modify one’s appearance.

This article examines who or what should be the target of feminist criticism. Throughout the discussion, the concept of memes is applied in analyzing systems such as patriarchy and feminism itself. Adapting Dawkins' theory on genes, this research puts forward the possibility that patriarchies and feminisms are memeplexes competing for the limited energy and memory space of humanity.

In a recent Response published in the Journal of Medical Ethics,1 Buturovic provides two criticisms of my argument in ‘Is the exclusion of psychiatric patients from access to physician-assisted suicide discriminatory?’2 First, Buturovic argues that my argument effectively ‘erases the distinction between healthy adults and patients (whether somatic or psychiatric) essentially implying that PAS [physician-assisted suicide] should be available to all, for all reasons or, ultimately no reason’ (Buturovic,1 pg. 1). Second, Buturovic argues that opening the doors to medical assistance (...) in dying (MAID) for psychiatric patients could have a number of undesirable implications. In particular, Buturovic highlights the potential negative implications for relations of trust in medicine—psychiatry in particular—along with potential effects on the rate of organ donation. I would here like to respond to these two criticisms. In short, my response to Buturovic’s first argument is that the slope is not nearly as slippery as Buturovic suggests. The reason for this is that the plausibility of Buturovic’s argument rests on a significant misinterpretation of my argument, along with an important equivocation in her own. Buturovic argues that, under the three criteria that I propose for the provision of MAID—sufficient decision-making capacity, demonstrated treatment resistance, and a lack of substantially negative implications for existing standards of psychiatric treatment and research—the provision of MAID for trivial reasons, even no reason at all, is justifiable. The main problem with this argument is that I propose no such positive criteria. My argument is that none of the three arguments addressed in my previous paper are sufficient to justify the exclusion of any and all psychiatric patients from access to MAID. I do not claim, in other words, that any individual …. (shrink)

Background Men with antisocial personality disorder show lifelong abnormalities in adaptive decision making guided by the weighing up of reward and punishment information. Among men with antisocial personality disorder, modifi cation of the behaviour of those with additional diagnoses of psychopathy seems particularly resistant to punishment. Methods We did a case-control functional MRI (fMRI) study in 50 men, of whom 12 were violent off enders with antisocial personality disorder and psychopathy, 20 were violent off enders with antisocial personality disorder but (...) not psychopathy, and 18 were healthy non-off enders. We used fMRI to measure brain activation associated with the representation of punishment or reward information during an event-related probabilistic response-reversal task, assessed with standard general linear-model-based analysis. Findings Offenders with antisocial personality disorder and psychopathy displayed discrete regions of increased activation in the posterior cingulate cortex and anterior insula in response to punished errors during the task reversal phase, and decreased activation to all correct rewarded responses in the superior temporal cortex. This finding was in contrast to results for off enders without psychopathy and healthy non-off enders. Interpretation Punishment prediction error signalling in off enders with antisocial personality disorder and psychopathy was highly atypical. This finding challenges the widely held view that such men are simply characterised by diminished neural sensitivity to punishment. Instead, this fi nding indicates altered organisation of the information processing system responsible for reinforcement learning and appropriate decision making. This difference between violent offenders with antisocial personality disorder with and without psychopathy has implications for the causes of these disorders and for treatment approaches. (shrink)

In this essay, I look at more or less sympathetic portrayals of egoists in film. I start by explaining some basic concepts: psychological egoism; ethical egoism; default egoism; rational egoism; egotism; cynicism; narcissism; and psychopathy. I then review in-depth two excellent WWII films, Stalag 17 and The Bridge on the River Kwai. I note that the key protagonist in both pictures is the same type of character—both played by the same fine actor, William Holden. The main protagonist in both is (...) a soldier in a POW camp, who appears completely egoistic; however, in both cases, the movie shows that he is just a man acting for self-preservation, but within moral limits. The character in both cases is certainly not an egotist, nor a narcissist, much less a psychopath. (shrink)

This essay is my critical review of Al Gini and Alexei Marcoux’s fine text, The Ethics of Business. Unlike most business ethics texts, Gini/Marcoux recognize that most businesses are small, and that business is not inherently immoral and always in need of reform. And they put their focus on using ethical theory to find action-guiding principles to help guide business behavior. Moreover, they adopt the Schumpeterian view that business is an entrepreneurial activity—one that not merely executes transactions, but seeks them (...) out. I critically probe a number of issues with their book such as their reliance upon virtue ethics as their main ethical theory, and their view that trust plays an overwhelming role in business.

In this essay, I look at two negative portrayals of egoism. I summarize in detail the superb All About Eve—which won six Academy Awards, including Best Picture. The movie is about the rise of a ruthlessly ambitious actress, and how she treats her main competitor. Eve Harrington worms her way into top theatrical actress Margo Channing’s inner circle by pretending to be an admirer, but she is really a schemer who wants to eclipse Margo’s star in the theater universe. However, (...) Eve runs into trouble when she attempts to manipulate tart-tongued theater critic, Addison de Witt. The movie portrays the New York theater industry as being full of narcissists. I then review the classic film noir The Third Man (1949), rated by the prestigious British Film Institute as the greatest film of the 20th century. The film centers around a charismatic, handsome criminal mastermind Harry Lime living in bombed-out post-War Vienna. Lime is a man of no conscience or empathy—a true psychopath. He cripples children by selling hospitals adulterated penicillin. But we (the audience) still feel sympathy for him. I end the piece by explaining the psychological mechanisms at work that give rise to our paradoxical sympathy. (shrink)

In this essay, I review in great detail Ian Garden’s outstanding book, The Third Reich’s Celluloid War. Garden begins by discussing propaganda theory and then discusses not just Nazi feature films and documentaries, but television as well. (The Nazis had the earliest TV network). All in all, the regime produced over 1,300 feature films during its time in power. Garden also compares Nazi propaganda films to British and American ones.

Résumé Si l’absence de moralité des psychopathes a été largement étudiée, il existe peu de recherches sur leurs capacités esthétiques. Pourtant, beaucoup d’études cliniques de cas montrent qu’ils présentent un grave déficit dans ce domaine. Cet article se propose d’en chercher les causes. Il analyse les forces et les limites de l’hypothèse d’un manque d’empathie pour expliquer ces carences esthétiques, et montre pourquoi l’hypothèse d’un manque de distance psychique se révèle plus féconde. Celle-ci permet en outre de comprendre le lien (...) de l’esthétique et de l’éthique par leur filiation commune : elles ont pour socle commun la capacité à prendre de la distance par rapport à des intérêts étroitement égoïstes.

In this essay, I look at two films as possible exemplars of the Nietzschean view of egoism. Compulsion is based on the infamous 1924 Leopold and Loeb murder case. In the movie, two arrogant young men—one of whom admires Nietzsche and preaches the (apparently Nietzschean) view that the strong and superior don’t need to follow conventional morality—kill a boy to prove they can outsmart the unter-menschen police. For a different take on what Nietzsche may have had in mind as “the (...) Overman,” I also look at the film The Moon and Sixpence. Here the protagonist isn’t violent or aggressive, but a completely self-absorbed artist, who paints with genius but uses others without feeling any gratitude or friendship, let alone love. (shrink)

In this essay, I use four war movies to explore conflicts of loyalty and how they are resolved, all to illustrate W.D. Ross’ multiple rule deontologism. The films are all fine WWII movies: The Enemy Below; Decision Before Dawn; John Rabe; and The Bridge on the River Kwai. In my analysis of each, I show how the protagonists face conflicts of their loyalty to themselves, their countrymen, their friends, and humanity in general, and resolve them in the face of changing (...) factual backgrounds.

In this essay, I review a French-American gem of a movie, The Artist. This movie was an homage to the silent film era and is itself almost all silent. I discuss both the artistic and financial success of silent movies, and I praise this film for successfully interesting modern theater-goers despite its almost total lack of sound. The film won five Academy Awards, including Best Picture, Best Director, and—for its outstanding lead actor, Jean Dujardin—Best Actor. It is the only French-produced (...) movie to win Best Picture, and the only (almost entirely) silent movie to win Best Picture since the start of the Academy Awards in 1929. (shrink)

In this essay, I take up the question of why so many of the movies made by Hollywood are endless sequels, “prequels,” and remakes of prior blockbuster hits and so many are based on comic books (X-men, Superman, Batman, and so on). I tie the explanation in part to the aforementioned 1950 Supreme Court ruling prohibiting production companies, and in part to broader cultural changes. In particular, I argue that precisely because film producers can no longer make money from the (...) concessions (i.e., the purchases within the theater), but only of the ticket sales, the producers keep producing remakes of known popular movies, rather than make deeply original movies.

Paul C. Taylor’s essay, Black Reconstruction in Aesthetics, is concerned with the relationship between language—in particular, what Taylor refers to as “terms”—and how we construct and live in the world. Following theorist Fred Moten, Taylor argues that “terms” are the “tools” through which we put ourselves and things into “play”. That is, “terms” help to shape how, when, and why we enter into social space with others. The “term” that Taylor is concerned with is “reconstruction”. In particular, Taylor is concerned (...) with how philosopher John Dewey utilizes the “term”, and the social space enacted through his usage. Taylor queries what is missing in Dewey’s “term”—namely, “race” and the history of “racialization”—and what this might imply about the social space that Dewey’s “term” invites us to enter. (shrink)

Translated into Danish by Henrik Jøker Bjerre.

I begin by arguing that, for Kant, the pure category of substance has both a general content that is in play whenever we think of any entity as a substance as well as a more specific content that arises in conjunction with the thought of what Kant calls a positive noumenon. Drawing on this new “Dual Content” account of the pure category of substance, I offer new answers to two contested questions: What is the relation of the pure category to (...) phenomenal substance? What, if any, epistemic gains can we achieve when we apply the pure category to noumena? Regarding the first question, I argue that while phenomenal substance does not qualify as a substance according to the Inner-Simple Conception, it does qualify as one according to the Subsistence-Power Conception. Regarding the second question, I argue that, in the case of the substantiality of positive noumena, Kant’s account allows for justified conditional beliefs involving the Inner-Simple Conception. In the case of negative noumena, it allows for justified existential beliefs involving the Subsistence-Power Conception. (shrink)

Philosophers often rely on their own examples and intuitions, which can be problematic since philosophers are a small group with their own set of biases and limitations. Science fiction can assist with this problem through the provision of examples that are both designed by non-philosophers and intended to be thought-provoking and plausible. In particular, when philosophers teach, we can use science fiction for examples that raise relevant issues in interesting contexts, while also being fully fleshed out. In this paper, I (...) explain how I use Joss Whedon’s Firefly to teach political philosophy, ethics, and existentialism. I hope to show the usefulness of good science fiction for the purpose of teaching philosophy in new and engaging ways. (shrink)

ABSTRACT: Central to both James’s earlier psychology and his later philosophical views was a recurring distinction between percepts and concepts. The distinction evolved and remained fundamental to his thinking throughout his career as he sought to come to grips with its fundamental nature and significance. In this chapter, I focus initially on James’s early attempt to articulate the distinction in his 1885 article “The Function of Cognition.” This will highlight a key problem to which James continued to (...) return throughout his later philosophical work on the nature of our cognition, including in his famous “radical empiricist” metaphysics of “pure experience” around the turn of the century. We shall find that James grappled insightfully but ambivalently with the perceptual and conceptual dimensions of the “knowledge relation” or the “cognitive relation,” as he called it—or what, following Franz Brentano, philosophers would later call our object-directed thought or intentionality more generally. Some philosophers have once again returned to James’s work for crucial insights on this pivotal topic, while others continue to find certain aspects of his account to be problematic. What is beyond dispute is that James’s inquiries in this domain were both innovative and of lasting significance. (shrink)

This paper addresses five questions: First, what is trajectory of Western liberal ethics and politics in defining life, rights and citizenship? Second, how will neuro-remediation and other technologies change the definition of death for the brain injured and the cryonically suspended? Third, will people always have to be dead to be cryonically suspended? Fourth, how will changing technologies and definitions of identity affect the status of people revived from brain injury and cryonic suspension? I propose that Western liberal thought is (...) working towards a natural end, a “telos.” In response to a variety of biotechnologies, law and public opinion in liberal democracies will be forced to make explicit that the rights of a living thing are determined by its level of consciousness. I discuss the way that technology will force three clarifications about the value of consciousness, at the beginning, the end and boundaries of human life. Sentience and personhood will become the basis of moral concern, regardless of its media. Just as human rights have become independent of race, gender and property, rights will become independent of being a breathing human being. But even as we make this transition, the cryonically preserved are still likely to be considered dead for pragmatic reasons, albeit with gradually increasing rights as technology makes their reanimation increasingly probable. I suggest that it could be acceptable to cryonicists that the frozen continue to be defined as dead if assisted suicide can be legalized. Under a liberal assisted suicide policy cryonicists might be allowed to carry out suspension before a declaration of death, preserving the maximum amount of neural information. The gradual redefinition of life and personal identity in terms of psychological continuity will also have consequences for the legal status of the reanimated. If, due to information loss, the reanimated do not meet a threshold of psychological continuity, they may be considered new persons. Cryonicists may therefore wish to specify ahead of time whether they are still interested in being reanimated if pre-animation assessment suggests that the result will not meet the necessary threshold of continuity. Finally, I touch on the way that neural technology will fundamentally problematize the separate, autonomous self on which liberal democratic values are based, leading to a legal and political Singularity. It is this looming neural Singularity that makes the proposed liberal democratic telos a final stage in humanistic thought, before it is superceded by something radically different. (shrink)

Mathematicians often speak of conjectures as being confirmed by evidence that falls short of proof. For their own conjectures, evidence justifies further work in looking for a proof. Those conjectures of mathematics that have long resisted proof, such as the Riemann hypothesis, have had to be considered in terms of the evidence for and against them. In recent decades, massive increases in computer power have permitted the gathering of huge amounts of numerical evidence, both for conjectures in pure mathematics and (...) for the behavior of complex applied mathematical models and statistical algorithms. Mathematics has therefore become (among other things) an experimental science (though that has not diminished the importance of proof in the traditional style). We examine how the evaluation of evidence for conjectures works in mathematical practice. We explain the (objective) Bayesian view of probability, which gives a theoretical framework for unifying evidence evaluation in science and law as well as in mathematics. Numerical evidence in mathematics is related to the problem of induction; the occurrence of straightforward inductive reasoning in the purely logical material of pure mathematics casts light on the nature of induction as well as of mathematical reasoning.

According to the view that there is moral encroachment in epistemology, whether a person has knowledge of p sometimes depends on moral considerations, including moral considerations that do not bear on the truth or likelihood of p. Defenders of moral encroachment face a central challenge: they must explain why the moral considerations they cite, unlike moral bribes for belief, are reasons of the right kind for belief (or withheld belief). This paper distinguishes between a moderate and a radical version of (...) moral encroachment. It shows that, while defenders of moderate moral encroachment are well-placed to meet the central challenge, defenders of radical moral encroachment are not. The problem for radical moral encroachment is that it cannot, without taking on unacceptable costs, forge the right sort of connection between the moral badness of a belief and that belief’s chance of being false.

Recent theories of remembering and of reference (or singular thought) have de-emphasised the role causation was thought to play in mid- to late-twentieth century theorising. According to postcausal theories of remembering, such as simulationism, instances of the psychofunctional kind _remembering_ are not, in principle, dependent on appropriate causal chains running from some event(s) remembered to the occurrence of remembering. Instead they depend only on the reliability, or proper functioning, of the cognitive system responsible for their production. According to broadly reliabilist (...) accounts of _singular thought_, such thought is not, in principle, dependent on causal chains running from the object(s) of thought to the occurrence of thinking. Despite this common trend, accounts of the two phenomena have been pursued separately. In this paper, we argue that the two lines of research can profitably converge to address a neglected question: what enables occurrences of remembering to _refer_ to particular events, and what determines _which_ event a given occurrence of remembering refers to? We motivate and present a reliabilist account of reference-fixing for postcausal theories of remembering, focusing in particular on simulationism. We then show that this account draws attention to the possibility of _referential mnemic confabulation:_ cases where the reliability requirement for reference is met despite the improper functioning of the episodic construction system. We suggest that this makes sense of some underdiscussed phenomena described in the empirical literature on confabulation and argue that our reliabilist account of mnemic reference-fixing accommodates these more naturally than could causal theories of remembering.

Previous studies have shown that zinc deficiency leads to apoptosis of neuronal precursor cells in vivo and in vitro. In addition to the role of p53 as a nuclear transcription factor in zinc deficient cultured human neuronal precursors (NT-2), we have now identified the translocation of phosphorylated p53 to the mitochondria and p53-dependent increases in the pro-apoptotic mitochondrial protein BAX leading to a loss of mitochondrial membrane potential as demonstrated by a 25% decrease in JC-1 red:green fluorescence ratio. Disruption of (...) mitochondrial membrane integrity was accompanied by efflux of the apoptosis inducing factor (AIF) from the mitochondria and translocation to the nucleus with a significant increase in reactive oxygen species (ROS) after 24 h of zinc deficiency. Measurement of caspase cleavage, mRNA, and treatment with caspase inhibitors revealed the involvement of caspases 2, 3, 6, and 7 in zinc deficiency-mediated apoptosis. Down-stream targets of caspase activation, including the nuclear structure protein lamin and polyADP ribose polymerase (PARP), which participates in DNA repair, were also cleaved. Transfection with a dominant-negative p53 construct and use of the p53 inhibitor, pifithrin- ␮, established that these alterations were largely dependent on p53. Together these data identify a cascade of events involving mitochondrial p53 as well as p53-dependent caspase-mediated mechanisms leading to apoptosis during zinc deficiency. (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

Immoralists hold that in at least some cases, moral fl aws in artworks can increase their aesthetic value. They deny what I call the valence constraint: the view that any effect that an artwork’s moral value has on its aesthetic merit must have the same valence.

In this paper I argue that these arguments fail, and that this failure reveals something deep and interesting about the relationship between cognitive and moral value. (...) In the fi nal section I offer a positive argument for the valence constraint. (shrink)
