In Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning and makes an ethical case for biotechnology that is both forthright and rigorous. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us with immunity (...) from cancer and HIV/AIDS. Further, Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he says, it's not only morally defensible to enhance ourselves; in some cases, it's morally obligatory. In a new preface, Harris offers a glimpse at the new science and technology to come, equipping readers with the knowledge to assess the ethics and policy dimensions of future forms of human enhancement.

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. (shrink)

The paper contrasts Lennart Nordenfelt’s normative theory of health with the naturalists’ point of view, especially in the version developed by Christopher Boorse. In the first part it defends Boorse’s analysis of disease against the charge that it falls short of its own standards by not being descriptive. The second part of the paper sets out to analyse the positive concept of health and introduces a distinction between a positive definition of health (‘health’ is not defined as absence of disease (...) but in positive terms) and a positive conception of health (health is seen as an ideal). An objection against Nordenfelt’s account is developed by making use of a specific example of an ambitious athlete. It is stated that Nordenfelt’s conceptualisation includes too many phenomena under the umbrella of ill health. An ideal conception of health like Nordenfelt’s is in danger of supporting medicalization. In conclusion, although Nordenfelt’s theory is not altogether rejected and even seen in congruence with Boorse’s account, it is claimed that the naturalistic framework should obtain conceptual priority.

This paper contains an attempt at constructing a semantic framework for the field of health enhancement. The latter is here conceived as an extremely general category covering the whole area of health care and health promotion. With this framework as a basis I attempt to define the place of medicine within the enterprise of health enhancement. I finally indicate some normative issues for the future, in particular problems and possible developments for medicine as a species of health enhancement.

The treatment-enhancement distinction draws a line between services or interventions meant to prevent or cure conditions that we view as diseases or disabilities and interventions that improve a condition that we view as a normal function or feature of members of our species. The line drawn here is widely appealed to in medical practice and medical insurance contexts, as well as in our everyday thinking about the medical services we do and should assist people in obtaining.

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

The hopes and fears expressed in the debate on human enhancement are not always based on a realistic assessment of the expected possibilities. Discussions about extreme scenarios may at times obscure the ethical and policy issues that are relevant today. This paper aims to contribute to an adequate and ethically sound societal response to actual current developments. After a brief outline of the ethical debate concerning neuro-enhancement, it describes the current state of the art in psychopharmacological science and current uses (...) of psychopharmacological enhancement, as well as the prospects for the near future. It then identifies ethical issues regarding psychopharmacological enhancements that require attention from policymakers, both on the professional and on the governmental level. These concern enhancement research, the gradual expansion of medical categories, off-label prescription and responsibility of doctors, and accessibility of enhancers on the Internet. It is concluded that further discussion on the advantages and drawbacks of enhancers on a collective social level is still needed. (shrink)

When philosophers address personal identity, they usually explore numerical identity: what are the criteria for a person's continuing existence? When non-philosophers address personal identity, they often have in mind narrative identity: Which characteristics of a particular person are salient to her self-conception? This book develops accounts of both senses of identity, arguing that both are normatively important, and is unique in its exploration of a range of issues in bioethics through the lens of identity. Defending a biological view of our (...) numerical identity and a framework for understanding narrative identity, DeGrazia investigates various issues for which considerations of identity prove critical: the definition of death; the authority of advance directives in cases of severe dementia; the use of enhancement technologies; prenatal genetic interventions; and certain types of reproductive choices. He demonstrates the power of personal identity theory to illuminate issues in bioethics as they bring philosophical theory to life. (shrink)

Despite being co-opted by economists and politicians for their own purposes, ‘welfare’ traditionally refers to well-being, and it is in this sense that L. W. Sumner understands the term. His book is a clear, careful, and well-crafted investigation into major theories of welfare, accompanied by a one-chapter defense of “welfarism,” the view that welfare is the only foundational value necessary for ethics. Sumner himself is attracted to utilitarianism, but he makes no commitment to it in this work, which will be (...) of interest to many moral philosophers. (shrink)

The purpose of this article is to present a normative theory of the goals of medicine (a theory that tells us in what respects medicine should benefit the patient) that is both comprehensive and unified. A review of the relevant literature suggests that there are at least seven plausible goals that are irreducible to each other, namely to promote functioning, to maintain or restore normal structure and function, to promote quality of life, to save and prolong life, to help the (...) patient to cope well with her condition, to improve the external conditions under which people live, and to promote the growth and development of children. However, it seems that all these goals need to be qualified in different ways, e.g. it does not seem reasonable to improve physiological function or functional ability unless this is expected to have positive effects on quality of life and/or length of life, or to improve the quality of life in any respect, or by any means. These qualifications all suggest that the proposed goals are, as goals, conceptually, and not just causally, related to one another, and that they should therefore not be regarded in isolation. Instead, we should think of the medical enterprise as having a multidimensional goal structure rather than a single goal. In order to depict clearly how the different goals are related to one another, a multidimensional model is constructed. (shrink)

A basic question of medical ethics is whether the norms governing medical practice should be understood as the application of principles and rules of the common morality to medicine or whether some of these norms are internal or proper to medicine. In this article we describe and defend an evolutionary perspective on the internal morality of medicine that is defined in terms of the goals of clinical medicine and a set of duties that constrain medical practice in pursuit of these (...) goals. This perspective is developed by means of a critical examination of the essentialist conception of the internal morality of medicine advocated by Edmund Pellegrino and the critique of internal morality approaches by Robert Veatch and Tom Beauchamp.

ABSTRACT There is concern that the use of neuroenhancements to alter character traits undermines consumer's authenticity. But the meaning, scope and value of authenticity remain vague. However, the majority of contemporary autonomy accounts ground individual autonomy on a notion of authenticity. So if neuroenhancements diminish an agent's authenticity, they may undermine his autonomy. This paper clarifies the relation between autonomy, authenticity and possible threats by neuroenhancements. We present six neuroenhancement scenarios and analyse how autonomy accounts evaluate them. Some cases are (...) considered differently by criminal courts; we demonstrate where academic autonomy theories and legal reasoning diverge and ascertain whether courts should reconsider their concept of autonomy. We argue that authenticity is not an appropriate condition for autonomy and that new enhancement technologies pose no unique threats to personal autonomy. (shrink)

In recent years, neuroscience has been a particularly prolific discipline stimulating many innovative treatment approaches in medicine. However, when it comes to the brain, new techniques of intervention do not always meet with a positive public response, in spite of promising therapeutic benefits. The reason for this caution clearly is the brain’s special importance as “organ of the mind”. As such it is widely held to be the origin of mankind’s unique position among living beings. Likewise, on the level of (...) the individual human being, the brain is considered the material substrate of those traits that in combination render each person unique. In view of this preeminent significance of the brain, it is understandable that, in general, interventions into the brain are considered a delicate issue and that new techniques of intervention are scrutinised with particular care. However, in doing so it is important not to go to the opposite extreme and shy away from promising new therapeutic approaches for debilitating disorders of the brain. With respect to the new techniques of brain intervention a broad interdisciplinary perspective is required to discern irrational fear from justified concern. Hence, the Europäische Akademie established a project group consisting, on the one hand, of experts from different fields of medicine who have got first-hand experience of applying the techniques at issue and, on the other hand, of philosophers and a legal expert. The task of this team was to review the state of the art with respect to each single technique of intervening in the brain, to indicate future developments, and to address the ethical and legal issues common to all of them. The project’s outcome is the book at hand. (shrink)

The traditional contrast between naturalist and normativist disease concepts fails to capture the most salient features of the health concepts debate. By using health concepts as a window on background notions of medical science and ethics, I show how Christopher Boorse (an influential naturalist) and Lennart Nordenfelt (an influential normativist) actually share deep assumptions about the character of medicine. Their disease concepts attempt, in different ways, to shore up the same medical model. For both, health concepts function like demarcation criteria (...) in the philosophy of science: they mark off the jurisdiction of medical science, and protect it from an inappropriate intrusion of socioeconomic factors, which threaten the integrity of modern medicine. These views are challenged by new developments in healthcare such as managed care and total quality review. To frame the health concepts debate in a way that better captures the issues integral to these new developments, I advance a new way of reading the distinction between weak and strong normativists. Strong normativists are skeptical of the demarcation project, think facts and values cannot be disentangled, and hold that socioeconomic conditions unavoidably influence how pathology is understood. The new health concepts debate should be framed as one between weak and strong normativists, and it concerns how we should respond to the current developments in health care. (shrink)

Lies and deception are often used in the care for demented elderly and often with the best intentions. However, there is a strong moral presumption against all forms of lying and deceiving. The goal of this article is to examine and evaluate concrete examples of deception and lies in dementia care, while addressing some fundamental issues in the process.It is argued that because dementia slowly diminishes the capacities one needs to distinguish between truths and falsehoods, the ability to be lied (...) to also disappears. When the moral reasons to reject lying are explored, it becomes clear that most of them also hold where demented patients are concerned, though this also depends on the capacities of the patient. Lying, though prima facie wrong, can sometimes be justified with an appeal to well-being. The relationship between well-being and the truth is further explored. Two examples of deceiving demented patients for reasons of beneficence are discussed, from which it can be concluded that although in some cases beneficent lies or deception will not enhance patients’ well-being, there are circumstances in which they do. In general, methods that enhance the well-being of the patient without deception or lies should be favored above options that use deceit, and methods of getting the truth across without hurting the patient should be favored above blunt honesty. Finally, it is important to note that not only the patient but also the nursing and medical staff can be affected by the use of lies and deception. (shrink)

Deep-brain stimulation has been used to treat advanced Parkinson disease and other neurological and psychiatric disorders that have not responded to other treatments. While deep-brain stimulation can modulate overactive or underactive regions of the brain and thereby improve motor function, it can also cause changes in a patient’s thought and personality. This paper discusses the trade-offs between the physiological benefit of this technique and the potential psychological harm.

Advances in psychopharmacology raise the prospects of enhancing neurocognitive functions of humans by improving attention, memory, or mood. While general ethical reflections on psychopharmacological enhancement have been increasingly published in the last years, ethical criteria characterizing physicians’ role in neurocognitive enhancement and guiding their decision-making still remain highly unclear. Here it will be argued that also in the medical domain the use of cognition-enhancing drugs is not intrinsically unethical and that, in fact, physicians should assume an important role in gating (...) their usage. For finding normative orientation, concepts of disease, normality or medicine will not be helpful since—due to their cryptonormative nature—they rather hamper than allow targeted discussion and decision-making. As an alternative, the common and widely accepted bioethical criteria of beneficence, non-maleficence, autonomy and distributive justice allow a clinically applicable, highly differentiated context- and case-sensitive approach. By embedding decision-making in a participative physician–patient relationship extrinsic objections against neurocognitive enhancement (e.g. invalid perceptions about efficacy, benefit or risk; questionable voluntariness; restrained decision-making capacity) can be curtailed.

After distinguishing two different meanings of the notion of a morality internal to medicine and considering a hypothetical case of a society that relied on its surgeons to eunuchize priest/cantors to permit them to play an important religious/cultural role, this paper examines three reasons why morality cannot be derived from reflection on the ends of the practice of medicine: (1) there exist many medical roles and these have different ends or purposes, (2) even within any given medical role, there exists (...) multiple, sometimes conflicting ends, and, most critically, (3) the ends of any practice such as medicine must come from outside the practice, that is, from the basic ends or purposes of human living. The paper concludes by considering whether these ends external to medicine are universally part of the moral reality or whether they are socially constructed. The paper argues that, even if various cultural accounts of the common, universal morality are socially constructed, they may, nevertheless, be reflections, however, imperfect, of a more universal common morality that should be thought of as real. Therefore, the morality of medicine must come from a more fundamental morality external to medicine. That external morality will be socially constructed, but may nevertheless reflect an underlying common morality. (shrink)
