Neil Levy

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.

The United States Supreme Court hasrecently ruled that virtual child pornographyis protected free speech, partly on the groundsthat virtual pornography does not harm actualchildren. I review the evidence for thecontention that virtual pornography might harmchildren, and find that it is, at best,inconclusive. Saying that virtual childpornography does not harm actual children isnot to say that it is completely harmless,however. Child pornography, actual or virtual,necessarily eroticizes inequality; in a sexistsociety it therefore contributes to thesubordination of women.

Human beings are subject to a range of cognitive and affective limitations which interfere with our ability to pursue our individual and social goals. I argue that shaping our environment to avoid triggering these limitations or to constrain the harms they cause is likely to be more effective than genetic or pharmaceutical modifications of our capacities because our limitations are often the flip side of beneficial dispositions and because available enhancements seem to impose significant costs. I argue that carefully selected environmental interventions respect agents’ autonomy and are consistent with democratic decision making.

Neuroscience has dramatically increased understanding of how mental states and processes are realized by the brain, thus opening doors for treating the multitude of ways in which minds become dysfunctional. This book explores questions such as when is it permissible to alter a person's memories, influence personality traits or read minds? What can neuroscience tell us about free will, self-control, self-deception and the foundations of morality? The view of neuroethics offered here argues that many of our new powers to read ,alter and control minds are not entirely unparalleled with older ones. They have, however, expanded to include almost all our social, political and ethical decisions. Written primarily for graduate students, this book will appeal to anyone with an interest in the more philosophical and ethical aspects of the neurosciences.

I am grateful to the commentators, for their kind words and for their probing challenges. They range in the views they express, from those who seem to think I have not gone far enough in questioning the value of autonomy to those who think I have not challenged it at all. Given this diversity, it seems best to address their remarks sequentially.J D Trout is sympathetic to my project, and highlights his own work which supports it.1 Indeed, Trout's work—together with Michael Bishop and his own stand-alone writing—was an important influence on the views I advanced in the original paper. Unsurprisingly, given the influence his views have had on mine, I find little to disagree with in Bishop's proposals. What I find most useful in his commentary is his insistence that, given the data about human decision-making, some aspect of autonomy is threatened no matter what approach we take. As he points out, while policies that ‘depreciate a person's momentary wish’ might be seen as threatening some aspect of autonomy, policies that allow for unconstrained choice show at least an equal degree of ‘contempt for autonomy’ by making it probable that the agent makes a choice that she regrets because it is not in accordance with her own values. In the original paper I had argued that properly understood, autonomy supports policies that provide soft constraints on choice—constraints that steer and nudge, but which do not prevent the agent who insists on a particular course of action from taking it. Bishop may be right in suggesting that autonomy is not …
