This paper considers the phenomenon of lying and the implications it has for those subjects who are capable of lying. It is argued that lying is not just intentional untruthfulness, but is intentional untruthfulness plus an insincere invocation of trust. Understood in this way, lying demands of liars a sophistication in relation to themselves, to language, and to those to whom they lie which exceeds the demands on mere truth-tellers.

Frank Jackson has given us an elegant and important book. It is, by a long shot, the most sophisticated defense of the use of conceptual analysis in philosophy that has ever been offered. But we also we find it a rather perplexing book, for we can’t quite figure out what Jackson thinks a conceptual analysis is. And until we get clearer on that, we’re not at all sure that conceptual analysis, as Jackson envisions it, is possible. The main reason for (...) our perplexity is that Jackson seems to be making some empirical assumptions about people’s intuitions and the psychological mechanisms that give rise to them, though it is far from clear exactly what these empirical assumptions are. Moreover, on what is perhaps the most natural reading, he is making at least one assumption about which many cognitive scientists who study concepts have serious doubts. In the first of our two sections, we will elaborate this theme. Our goal, in that section, is not so much to criticize as to seek clarification. It is a great virtue of this journal’s multiple review format that critics can pose questions to authors, and the authors get to reply. So we hope that in his reply Jackson will help us understand his defense of conceptual analysis by explaining more clearly what his empirical assumptions are; and if he is indeed making an assumption that many cognitive scientists would challenge, we hope he will tell us why he thinks that challenge is misguided. In the second section, our stance will be more critical. There is one empirical assumption about which Jackson is admirably clear and explicit. However, we think there is now good reason to think that this assumption is false. (shrink)

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the (...) bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

Many philosophers claim that it cannot be the case that a person ought to perform an action if this person cannot perform this action. However, most of these philosophers do not give arguments for the truth of this claim. In this paper, I argue that it is plausible to interpret this claim in such a way that it is entailed by the claim that there cannot be a reason for a person to perform an action if it is impossible that (...) this person will perform this action. I then give three arguments for the truth of the latter claim, which are also arguments for the truth of the former claim as I interpret it. (shrink)

Walter Sinnott-Armstrong argues that 'ought' does not entail 'can', but instead conversationally implicates it. I argue that Sinnott-Armstrong is actually committed to a hybrid view about the relation between 'ought' and 'can'. I then give a tensed formulation of the view that 'ought' entails 'can' that deals with Sinnott-Armstrong's argument and that is more unified than Sinnott-Armstrong's view.

Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this conclusion. Our key premise relies on experiments we conducted which indicate that judgments of the folk elicited under higher quality cognitive or epistemic conditions are more likely to resemble those of the (...) philosopher. We end by showing how our experimental findings can help us better understand the Knobe Effect. (shrink)

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

An empirical study of people's intuitions about freedom of the will. We show that people tend to have compatiblist intuitions when they think about the problem in a more concrete, emotional way but that they tend to have incompatiblist intuitions when they think about the problem in a more abstract, cognitive way.

Many philosophers think that dispositions are necessarily intrinsic. However, there are no good positive arguments for this view. Furthermore, many properties (such as weight, visibility, and vulnerability) are dispositional but are not necessarily shared by perfect duplicates. So, some dispositions are extrinsic. I consider three main objections to the possibility of extrinsic dispositions: the Objection from Relationally Specified Properties, the Objection from Underlying Intrinsic Properties, and the Objection from Natural Properties. These objections ultimately fail.

A principle that many have found attractive is one that goes by the name “'Ought' Implies 'Can'.” According to this principle, one morally ought to do something only if one can do it. This essay has two goals: to show that the principle is false and to undermine the motivations that have been offered for it. Toward the end, a proposal about moral obligation according to which something like a restricted version of 'Ought' Implies 'Can' is true is floated. Though (...) no full-fledged argument for this proposal is offered, that it fits with a rather natural and intuitive picture of the structure of morality and seems to explain certain salient features of the debate over whether the principle is true, goes some way toward recommending it.

The past twenty years have seen an increase in the importance of the body in psychology, neuroscience, and philosophy of mind. This 'embodied' trend challenges the orthodox view in cognitive science in several ways: it downplays the traditional 'mind-as-computer' approach and emphasizes the role of interactions between the brain, body, and environment. In this article, I review recent work in the area of embodied cognitive science and explore the approaches each takes to the ideas of consciousness, computation and representation. Finally, (...) I look at the current relationship between orthodox cognitive science and the study of mental disorder, and consider the implications that the embodied trend could have for issues in psychopathology.

According to the principle of alternate possibilities (PAP), a person is morally responsible for an action only if he could have done otherwise. PAP underlies a familiar argument for the incompatibility of moral responsibility with determinism. I argue that Harry Frankfurt's famous argument against PAP is unsuccessful if PAP is interpreted as a principle about blameworthiness. My argument turns on the maxim that "ought implies can" as well as a "finely-nuanced" view of the object of blame. To reject PAP on (...) the blameworthiness interpretation, we must reject either this maxim or the finely-nuanced view or some other apparently innocuous assumption. (shrink)

Recently, psychologists have explored moral concepts including obligation, blame, and ability. While little empirical work has studied the relationships among these concepts, philosophers have widely assumed such a relationship in the principle that “ought” implies “can,” which states that if someone ought to do something, then they must be able to do it. The cognitive underpinnings of these concepts are tested in the three experiments reported here. In Experiment 1, most participants judge that an agent ought to keep a promise (...) that he is unable to keep, but only when he is to blame for the inability. Experiment 2 shows that such “ought” judgments correlate with judgments of blame, rather than with judgments of the agent’s ability. Experiment 3 replicates these findings for moral “ought” judgments and finds that they do not hold for nonmoral “ought” judgments, such as what someone ought to do to fulfill their desires. These results together show that folk moral judgments do not conform to a widely assumed philosophical principle that “ought” implies “can.” Instead, judgments of blame play a modulatory role in some judgments of obligation.

_The Disordered Mind: An Introduction to Philosophy of Mind and Mental Illness, second edition_ examines and explains, from a philosophical standpoint, what mental disorder is: its reality, causes, consequences, and more. It is also an outstanding introduction to philosophy of mind from the perspective of mental disorder. Revised and updated throughout, this _second edition_ includes new discussions of grief and psychopathy, the problems of the psychophysical basis of disorder, the nature of selfhood, and clarification of the relation between rationality and (...) mental disorder. Each chapter explores a central question or problem about mental disorder, including: what is mental disorder and can it be distinguished from neurological disorder? what roles should reference to psychological, cultural, and social factors play in the medical/scientific understanding of mental disorder? what makes mental disorders undesirable? Are they diseases? mental disorder and the mind–body problem is mental disorder a breakdown of rationality? What is a rational mind? addiction, responsibility and compulsion ethical dilemmas posed by mental disorder, including questions of dignity and self-respect. Each topic is clearly explained and placed in a clinical and philosophical context. Mental disorders discussed include clinical depression, dissociative identity disorder, anxiety, religious delusions, and paranoia. Several non-mental neurological disorders that possess psychological symptoms are also examined, including Alzheimer’s disease, Down’s syndrome, and Tourette’s syndrome. Containing chapter summaries and suggestions for further reading at the end of each chapter, _The Disordered Mind, second edition_ is a superb introduction to the philosophy of mental disorder for students of philosophy, psychology, psychiatry, and related mental health professions.

The principal aim of this book is to develop and defend an analysis of the concept of moral obligation. The analysis is neutral regarding competing substantive theories of obligation, whether consequentialist or deontological in character. What it seeks to do is generate solutions to a range of philosophical problems concerning obligation and its application. Amongst these problems are deontic paradoxes, the supersession of obligation, conditional obligation, prima facie obligation, actualism and possibilism, dilemmas, supererogation, and cooperation. By virtue of its normative (...) neutrality, the analysis provides a theoretical framework within which competing theories of obligation can be developed and assessed. This study is a major contribution to metaethics that will be of particular interest to all philosophers concerned with normative ethical theory. (shrink)

The claim that addiction is a brain disease is almost universally accepted among scientists who work on addiction. The claim’s attraction rests on two grounds: the fact that addiction seems to be characterized by dysfunction in specific neural pathways and the fact that the claim seems to the compassionate response to people who are suffering. I argue that neural dysfunction is not sufficient for disease: something is a brain disease only when neural dysfunction is sufficient for impairment. I claim that (...) the neural dysfunction that is characteristic of addiction is not sufficient for impairment, because people who suffer from that dysfunction are impaired, sufficiently to count as diseased, only given certain features of their context. Hence addiction is not a brain disease (though it is often a disease, and it may always involve brain dysfunction). I argue that accepting that addiction is not a brain disease does not entail a moralizing attitude toward people who suffer as a result of addiction; if anything, it allows for a more compassionate, and more effective, response to addiction.

In this paper, I present the results of an experimental study on intuitions about moral obligation (ought) and ability (can). Many philosophers accept as an axiom the principle known as “Ought Implies Can” (OIC). If the truth of OIC is intuitive, such that it is accepted by many philosophers as an axiom, then we would expect people to judge that agents who are unable to perform an action are not morally obligated to perform that action. The results of my experimental (...) study show that participants were more inclined to judge that an agent ought to perform an action than that the agent can perform the action. Overall, participants said that an agent ought to perform an action even when they said that the agent cannot do it. I discuss the implications of these results for the debate over OIC. (shrink)
