Neuroethics offers unprecedented opportunities as well as challenges. The challenges stem from the range of difficult ethical issues, which are confronted by neuroethicists. Issues concerning the nature of consciousness, of personal identity, free will, and so on, are all grist for the neuroethical mill. This article argues that this debate bears centrally on neuroethics and is significant for neuroethics. Whether the best interpretation of the facts to which proponents of the extended mind appeal is that the mind is genuinely extended, or merely embedded, or a reflection on these facts, are not in dispute but they reveal that the domain of neuroethics extends to all the processes and mechanisms subserving cognition, rather than just those processes and mechanisms internal to the skull. Once this fact is recognized both the scope of neuroethics and some of its characteristic concerns will be transformed.

Libertarianism in all its varieties is widely taken to be vulnerable to a serious problem of present luck, inasmuch as it requires indeterminism somewhere in the causal chain leading to action. Genuine indeterminism entails luck, and lack of control over the ensuing action. Compatibilism, by contrast, is generally taken to be free of the problem of present luck, inasmuch as it does not require indeterminism in the causal chain. I argue that this view is false: compatibilism is subject to a problem of present luck. Taken by itself, the compatibilist problem with present luck is less serious than the analogous problem confronting libertarianism. However, its effects are just as devastating for the entire account of freedom: the present luck confronting compatibilism is sufficient to undermine the compatibilist response to distant – constitutive – luck.

Janna Thompson has outlined ‘the apology paradox’, which arises whenever people apologize for an action or event upon which their existence is causally dependent. She argues that a sincere apology seems to entail a wish that the action or event had not occurred, but that we cannot sincerely wish that events upon which our existence depends had not occurred. I argue that Thompson’s paradox is a backward-looking version of Parfit’s (forward-looking) ‘non-identity problem’, where backward- and forward-looking refer to the perspective of an agent apologizing for or contemplating an action. The temporal perspective of the agent gives us the tools with which to dissolve the air of paradox which surrounds these problems. Each is best grasped from one temporal perspective, but the para- doxes arise when we attempt to examine it simultaneously from another. The evaluations appropriate to the apology paradox and the non-identity problem are therefore time-indexed.

This introduction traces the philosophical achievements of a thinker sonfluential that his death in 1980 brought 50,000 people on to the streets ofaris. The account of Jean-Paul Sartre - writer, journalist and intellectualornerstone of the 20th century - stretches from his early existential phaseo his later Marxist beliefs. With coverage of such major contemporary issuess human liberty, sociobiology, the ethics of work, and the influence ofenetics on ideas of individual freedom, Neil Levy uses a range of originalaterial not only to introduce Sartre and his work, but also to highlight hisontinuing relevance to today's moral and scientific climate. At the heart ofhis study is a focus on the ethical dimension of Jean-Paul Sartre'shilosophical thought: a focus which challenges us to consider more closelyhe shape of our lives, and the manner in which human beings should treat onenother.

We should react to deaf parents who choose to have a deaf child with compassion not condemnationThere has been a great deal of discussion during the past few years of the potential biotechnology offers to us to choose to have only perfect babies, and of the implications that might have, for instance for the disabled. What few people foresaw is that these same technologies could be deliberately used to ensure that children would be born with disabilities. That this is a real possibility, and not merely the thought experiment of a philosopher, is brought home to us by the decision of an American lesbian couple to select a deaf sperm donor in order to maximise the chances that their children, Jehanne and Gauvin, would be deaf like them.1 Their choice has sparked controversy, not only among medical ethicists, but in the opinion pages of newspapers across the world. Ought parents be permitted to make such choices?If the parents of Jehanne and Gauvin have done anything wrong, it must consist in violating their child’s right to an open future—limiting its future potential for choice.2 But what does it mean to respect this right?From the moment a child is born, her parents are making choices for her, which will powerfully shape her future. They will decide what kind of education she will have, what religious experiences, from among what group she can select friends. Thereby, they profoundly mould the person she will be and the life she will have.When this activity is carried out within certain, ill-defined, limits, it is in no way objectionable. It is not merely a ….

The question whether and when it is morally appropriate to withdraw life-support from patients diagnosed as being in the persistent vegetative state is one of the most controversial in bioethics. Recent work on the neuroscience of consciousness seems to promise fundamentally to alter the debate, by demonstrating that some entirely unresponsive patients are in fact conscious. In this paper, I argue that though this work is extremely important scientifically, it ought to alter the debate over the moral status of the patients very little. First, the data presented is complex and difficult to interpret; we should be wary of taking the claimed discovery entirely at face value (though the remaining questions will probably be settled by future research). Second, though the demonstration that some of the patients are in fact conscious would show that they are moral patients, and therefore beings whose welfare must be taken into account, it would not, by itself at any rate, show that they have an interest in continued life.

Consciousness, or its lack, is often invoked in debates in applied and normative ethics. Conscious beings are typically held to be significantly more morally valuable than non-consious, so that establishing whether a being is conscious becomes of critical importance. In this paper, I argue that the supposition that phenomenal consciousness explains the value of our experiences or our lives, and the moral value of beings who are conscious, is less well-grounded than is commonly thought. A great deal of what matters to us and about us can be explained by functional and representational properties that may not be sufficient for phenomenal consciousness. I conclude with some reflections on how these claims might affect debates in ethics

Some philosophers have criticized the use of psychopharmaceuticals on the grounds that even if these drugs enhance the person using them, they threaten their authenticity. Others have replied by pointing out that the conception of authenticity upon which this argument rests is contestable; on a rival conception, psychopharmaceuticals might be used to enhance our authenticity. Since, however, it is difficult to decide between these competing conceptions of authenticity, the debate seems to end in a stalemate. I suggest that we need not resolve this debate to end the stalemate. New technologies which alter the self can be understood within the framework of the first conception of authenticity, I suggest, not as threatening the authentic self, but rather as bringing the outward appearance of the self into line with its deepest essence. Since psychopharmaceutical use can plausibly be understood on this model, it can be seen as enhancing our authenticity on either conception

Ned Block has influentially distinguished two kinds of consciousness, access and phenomenal consciousness. He argues that these two kinds of consciousness can dissociate, and therefore we cannot rely upon subjective report in constructing a science of consciousness. I argue that none of Block's evidence better supports his claim than the rival view, that access and phenomenal consciousness are perfectly correlated. Since Block's view is counterintuitive, and has wildly implausible implications, the fact that there is no evidence that better supports it than the rival view should lead us to reject it.
