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)

I consider a familiar argument for two-boxing in Newcomb's Problem and find it defective because it involves a type of divergence from standard Baysian reasoning, which, though sometimes justified, conflicts with the stipulations of the Newcomb scenario. In an appendix, I also find fault with a different argument for two-boxing that has been presented by Graham Priest.

My subject is the theory of blame recently propounded by George Sher in his book, In Praise of Blame. I argue that although Sher has succeeded in capturing a number of genuine features of the concept of blame, there is an important element that he has omitted, which is the fact that necessarily, when A blames B for something and expresses this to B, A will realise that B is likely to find this unpleasant. The inclusion of the latter element (...) renders the question of whether any agent ever deserves blame a more open one than Sher allows. (shrink)

I defend an argument from Lauren Ashwell and Eric Marcus to the effect that the zombie idea is meaningless. I consider whether this idea could be saved from the force of the argument by adopting a projectivist account of third-person consciousness ascriptions. I decide that it cannot, but endorse that account anyway.

Are embryos deserving of moral consideration in our actions? A standard view suggests that embryos are considerable only if they have interests. One argument for embryonic interests contends that embryos are harmed by death because they are deprived of valuable future lives as adult persons. Some have challenged this argument on the grounds that embryos aren’t identical to adults: either due to the potential for embryos to twin or because we do not exist until the fetus develops consciousness. These arguments (...) fail to show that embryos do not have future adult lives. There is a better reason to think that embryos cannot have interests; namely, because they are not capable of having desires. Others have held this view but have not sufficiently justified it. The justification lies in the fact that the capacity for desires is necessary to make sense of the normativity of interests. (shrink)

In her book, Moral Status, Mary Anne Warren defends a comprehensive theory of the moral status of various entities. Under this theory, she argues that animals may have some moral rights but that their rights are much weaker in strength than the rights of humans, who have rights in the fullest, strongest sense. Subsequently, Warren believes that our duties to animals are far weaker than our duties to other humans. This weakness is especially evident from the fact that Warren believes (...) that it is frequently permissible for humans to kill animals for food. Warren’s argument for her view consists primarily in the belief that we have inevitable practical conflicts with animals that make it impossible to grant them equal rights without sacrificing basic human interests. However, her arguments fail to justify her conclusions. In particular, Warren fails to justify her beliefs that animals do not have an equal right to life and that it is permissible for humans to kill animals for food. (shrink)

A review of Andrew Melnyk, A Physicalist Manifesto: Thoroughly Modern Materialism (Cambridge University Press, 2003).

Andrew Huddleston’s book sets out a vision of Nietzsche as a philosopher of culture. His approach sheds light on some familiar problems and opens up a new way of thinking about cultural criticism. Nietzsche’s concern, he argues, lies with both the instrumental and final value of both individuals and whole cultures. In terms of the Anglophone secondary literature, this places Huddleston between Leiter, who tends to suggest that individuals are all that matters, and Young, who tends to suggest that (...) communities are all that matters. A repeated claim is that Nietzsche evaluates cultures in a manner that is analogous to the evaluation of art, and much of the book involves exploring the subtleties of what that analogy... (shrink)

Egan argues against Lewis’s view that properties are sets of actual and possible individuals and in favour of the view that they are functions from worlds to extensions (sets of individuals). Egan argues that Lewis’s view implies that 2nd order properties are never possessed contingently by their (1st order) bearers, an implication to which there are numerous counter-examples. And Egan argues that his account of properties is more commensurable with the role they play as the semantic values of predicates than (...) is Lewis’s. (shrink)

It is now over twenty years since Premack and Woodruff posed the question, ‘Does the chimpanzee have a theory of mind?’—‘by which we meant’, explained Premack in a later reappraisal, ‘does the ape do what humans do: attribute states of mind to the other one, and use these states to predict and explain the behaviour of the other one? For example, does the ape wonder, while looking quizzically at another individual, What does he really want? What does he believe? What (...) are his intentions? '. (shrink)

Public reason as a political ideal aims to reconcile reasonable disagreement; however, is public reason itself the object of reasonable disagreement? Jonathan Quong, David Estlund, Andrew Lister, and some other philosophers maintain that public reason is beyond reasonable disagreement. I argue this view is untenable. In addition, I consider briefly whether or not two main versions of the public reason principle, namely, the consensus version and the convergence version, need to satisfy their own requirements. My discussion has several important (...) implications for the debate on public reason. (shrink)

Rawls's theory of political obligation attempts to avoid the obvious flaws of a Lockean consent model. Rawls rejects a requirement of consent for two reasons: First, the consent requirement of Locke’s theory was intended to ensure that the liberty and equality of the contractors was respected, but this end is better achieved by the principles chosen in the original position, which order the basic structure of a society into which citizens are born. Second, "basing our political ties upon a principle (...) of obligation would complicate the assurance problem." Instead, Rawls offers a duty-based account, whereby we are duty-bound to support and comply with just institutions that apply to us. A. John Simmons argues that Rawls cannot meet the particularity requirement of establishing political obligation to only one state. I assess the response that this requirement can be met by the political constructivist element of Rawls's theory. I conclude that there are fatal flaws in this response. (shrink)

The two justificatory roles of the social contract are establishing whether or not a state is legitimate simpliciter and establishing whether any particular individual is politically obligated to obey the dictates of its governing institutions. Rawls's theory is obviously designed to address the first role but less obviously the other. Rawls does offer a duty-based theory of political obligation that has been criticized by neo-Lockean A. John Simmons. I assess Simmons's criticisms and the possible responses that could be (...) made to them, including those offered by Samuel Freeman. I conclude they rest on a Rawlsian equivocation and ultimately fail. (shrink)

Over the years a few authors have argued that Rawls’s ideal theory of justice is useless for the real world. This criticism has been largely ignored by Rawlsians, but in the light of a recent accumulation of such criticisms, some authors (in particular Holly Lawford-Smith, A. John Simmons, Zofia Stemplowska and Laura Valentini) have tried to defend ideal theory. In this article I will recapitulate the precise problem with Rawls’s ideal theory, argue that some of Rawls’s defenders misconceive it, (...) and show that recent attempts to rescue Rawls’s ideal theory from the charge of being useless fail. While there are useful kinds of ideal theory, Rawls’s is not one of them. In addition, Rawls’s very tentative suggestions for some kind of bridge between ideal and non-ideal theory are contradictory insofar as they implicitly presuppose the non-existence of the problem they are meant to solve. Thus, Rawls’s “non-ideal theory” too, is useless, and not so much a theory at all but a set of ad hoc stipulations. Finally, I will show that certain attempts within the global justice debate to use some variation of the original position to directly derive guidelines for the real world are misguided and yield no useful results.

Scholarly critiques of the just war tradition have grown in number and sophistication in recent years to the point that available publications now provide the basis for a more philosophically challenging Peace Studies course. Focusing on just a few works published in the past several years, this review explores how professional philosophers are reclaiming the terrain long dominated by the approach of political scientist Michael Walzer. On center stage are British philosopher David Rodin’s critique of the self-defensejustification for war and (...) American philosopher Andrew Fiala’s skeptical assessment of the just war tradition in its entirety. Also considered is a collection of more narrowly focused critiques by philosophers and some highly relevant extra-philosophical studies regarding the social interconnections between authority and violence.

The principle of fair play is widely thought to require simply that costs and benefits be distributed fairly. This gloss on the principle, while not entirely inaccurate, has invited a host of popular objections based on misunderstandings about fair play. Central to many of these objections is a failure to treat the principle of fair play as a transactional principle—one that allocates special obligations and rights among persons as a result of their interactions. I offer an interpretation of the principle (...) of fair play that emphasizes its similarities to another transactional principle: consent. This interpretation reveals that playing fair requires one to reciprocate specifically by following the rules of the cooperative scheme from which one benefits, just as consent requires one to act according to the terms of an agreement. I then draw on the comparison with consent to reply to some popular and persistent objections to the principle. (shrink)

A private property account is central to a liberal theory of justice. Much of the appeal of the Lockean theory stems from its account of the so-called `enough-and-as-good' proviso, a principle which aims to specify each employable person's fair share of the earth's material resources. I argue that to date Lockeans have failed to show how the proviso can be applied without thereby undermining a guiding intuition in Lockean theory. This guiding intuition is that by interacting in accordance with the (...) proviso persons interact as free and equal, or as reciprocally subject to the `laws of nature' rather than as subject to one another's arbitrary will. Because Locke's own and contemporary Lockean conceptions of the proviso subject some persons to some other persons' arbitrary will, the proviso so conceived cannot function as it should, namely as a principle that restricts interacting persons' actions reciprocally and thereby enables Lockean freedom under law.

Some political philosophers have judged that it is absurd to think that there can be unintentional consent. In this paper, I present an example of unintentional consent, which I refer to as the adapted boardroom example. I consider reasons for denying that this is an example of unintentional consent, but find that these reasons are unconvincing.

One of the most intriguing – and arguably counter-intuitive – doctrines defended by environmental philosophers is that of positive aesthetics, the thesis that all of nature is beautiful. The doctrine has attained philosophical respectability only comparatively recently, thanks in no small part to the work of Allen Carlson, one of its foremost defenders. In this paper, we argue that the doctrine can be found much earlier in the work of Gottfried Wilhelm Leibniz who devised and defended a version of positive (...) aesthetics in the early modern period, grounded in a conception of the world as a world of monads, each of which individually fulfils the rationalist aesthetic criteria of multiplicity-in-unity and that taken together ensure that the world as a whole is a harmoniously ordered system of multiple and diverse individuals, whose intelligible order and variety is made known to us through natural scientific endeavour. In showing this, we advance two further theses: first, that Leibniz's vers.. (shrink)

Smith makes his case against V-ism by appeals to (i) plant sentience, and (ii) the Transitivity of Eating principle [by which V-ans eat animals, since plants feed on decomposed animals]. By (i), V-ans are inconsistent in their prohibitions; by (ii) V-ism is impossible. -/- But, I argue, Smith and his beloved omnivore animists face similar pressures, insofar as they prohibit cannibalism.

In a recent article, Arthur Applbaum contributes a new view—legitimacy as a moral power—to the debate over the concept of political legitimacy. Applbaum rejects competing views of legitimacy, in particular legitimacy as a claim-right to have the law obeyed, for mistakenly invoking substantive moral argument in the conceptual analysis, and concludes that “at the core of the concept—what legitimacy is” is only a Hohfeldian moral power. In this article, I contend that: (1) Applbaum’s view of legitimacy, when fully unfolded, refers (...) to more than a mere moral power and should therefore be rejected even by his own standards; (2) Applbaum’s rejection of competing views of legitimacy ultimately relies on a claim that he does not successfully defend, namely, the claim that moral duties are of absolute rather than prima facie force.

This book aims to apply recent thinking in philosophy to the age-old problem of the meaning of life, and to do so in a way that is useful to atheists, agnostics, and humanists. The book reorients the search for meaning away from a search for purpose and toward a search for what truly matters, and criticizes our society's prevailing theory of value, the preference satisfaction theory of the economists. It next argues that emotions are our best guides to what matters (...) in life, and shows how emotional judgments about what matters can be true. Finally it discusses how a meaningful life can be lived, describes the role of justice, freedom, identity, and culture in its construction, and compares the meaningful with the happy life. Andrew Kernohan has a Ph.D in philosophy from the University of Toronto and is an Adjunct Professor at Dalhousie University. He is the author of Liberalism, Equality, and Cultural Oppression (Cambridge University Press, 1998) and various articles in professional philosophy journals. (shrink)

The essays in this volume explore those aspects of Kant’s writings which concern issues in the philosophy of mind. These issues are central to any understanding of Kant’s critical philosophy and they bear upon contemporary discussions in the philosophy of mind. Fourteen specially written essays address such questions as: What role does mental processing play in Kant’s account of intuition? What kinds of empirical models can be given of these operations? In what sense, and in what ways, are intuitions object-dependent? (...) How should we understand the nature of the imagination? What is inner sense, and what does it mean to say that time is the form of inner sense? Can we cognize ourselves through inner sense? How do we self-ascribe our beliefs and what role does self-consciousness play in our judgments? Is the will involved in judging? What kind of knowledge can we have of the self ? And what kind of knowledge of the self does Kant proscribe? These essays showcase the depth of Kant’s writings in the philosophy of mind, and the centrality of those writings to his wider philosophical project. Moreover, they show the continued relevance of Kant’s writings to contemporary debates about the nature of mind and self. Contents: 0. Introduction Anil Gomes and Andrew Stephenson 1.

This paper explains and defends a belief-first view of the relationship between belief and credence. On this view, credences are a species of beliefs, and the degree of credence is determined by the content of what is believed. We begin by developing what we take to be the most plausible belief-first view. Then, we offer several arguments for it. Finally, we show how it can resist objections that have been raised to belief-first views. We conclude that the belief-first view is (...) more plausible than many have previously supposed. (shrink)

This paper formalizes part of the cognitive architecture that Kant develops in the Critique of Pure Reason. The central Kantian notion that we formalize is the rule. As we interpret Kant, a rule is not a declarative conditional stating what would be true if such and such conditions hold. Rather, a Kantian rule is a general procedure, represented by a conditional imperative or permissive, indicating which acts must or may be performed, given certain acts that are already being performed. These (...) acts are not propositions; they do not have truth-values. Our formalization is related to the input/ output logics, a family of logics designed to capture relations between elements that need not have truth-values. In this paper, we introduce KL3 as a formalization of Kant’s conception of rules as conditional imperatives and permissives. We explain how it differs from standard input/output logics, geometric logic, and first-order logic, as well as how it translates natural language sentences not well captured by first-order logic. Finally, we show how the various distinctions in Kant’s much-maligned Table of Judgements emerge as the most natural way of dividing up the various types and sub-types of rule in KL3. Our analysis sheds new light on the way in which normative notions play a fundamental role in the conception of logic at the heart of Kant’s theoretical philosophy. (shrink)

Many think that Pascal’s Wager is a hopeless failure. A primary reason for this is because a number of challenging objections have been raised to the wager, including the “many gods” objection and the “mixed strategy” objection. We argue that both objections are formal, but not substantive, problems for the wager, and that they both fail for the same reason. We then respond to additional objections to the wager. We show how a version of Pascalian reasoning succeeds, giving us a (...) reason to pay special attention to the infinite consequences of our actions. (shrink)

Philosophers commonly say that beliefs come in degrees. Drawing from the literature, I make precise three arguments for this claim: an argument from degrees of confidence, an argument from degrees of firmness, and an argument from natural language.

On the basis of these arguments, I conclude (...) that beliefs do not come in degrees. (shrink)

Harry Frankfurt has argued that Descartes’s madness doubt in the First Meditation is importantly different from his dreaming doubt. The madness doubt does not provide a reason for doubting the senses since were the meditator to suppose he was mad his ability to successfully complete the philosophical investigation he sets for himself in the first few pages of the Meditations would be undermined. I argue that Frankfurt’s interpretation of Descartes’s madness doubt is mistaken and that it should be understood as (...) playing the same role as his more famous dreaming doubt. I focus my discussion around four questions: (Q1) What does the meditator have in mind when speaking of madness?, (Q2) Why does the meditator so quickly dismiss the madness doubt but take seriously the dreaming doubt?, (Q3) Does the madness doubt have the same scope as the dreaming doubt?, and (Q4) Why does the meditator bring up the madness doubt at all?

This article presents a critical reevaluation of the thesis—closely associated with H. L. A. Hart, and central to the views of most recent legal philosophers—that the idea of state coercion is not logically essential to the definition of law. The author argues that even laws governing contracts must ultimately be understood as “commands of the sovereign, backed by force.” This follows in part from recognition that the “sovereign,” defined rigorously, at the highest level of abstraction, is that person or entity (...) identified by reference to game theory and the philosophical idea of “convention” as the source of signals with which the subject population has become effectively locked, as a group, into conformity.

‘There is no place in the phenomenology of fully absorbed coping’, writes Hubert Dreyfus, ‘for mindfulness. In flow, as Sartre sees, there are only attractive and repulsive forces drawing appropriate activity out of an active body’1. Among the many ways in which history animates dynamical systems at a range of distinctive timescales, the phenomena of embodied human habit, skilful movement, and absorbed coping are among the most pervasive and mundane, and the most philosophically puzzling. In this essay we examine both (...) habitual and skilled movement, sketching the outlines of a multidimensional framework within which the many differences across distinctive cases and domains might be fruitfully understood. Both the range of movement phenomena which can plausibly be seen as instances of habit or skill, and the space of possible theories of such phenomena are richer and more disparate than philosophy easily encompasses. We seek to bring phenomenology into contact with relevant movements in psychological theories of skilful action, in the belief that phenomenological philosophy and cognitive science can be allies rather than antagonists.
