As we learn more about the human brain, novel biotechnological means to modulate human behaviour and emotional dispositions become possible. These technologies could be used to enhance our morality. Moral bioenhancement, an instance of human enhancement, alters a person’s dispositions, emotions or behaviour in order to make that person more moral. I will argue that moral bioenhancement could be carried out in three different ways. The first strategy, well known from science fiction, is behavioural enhancement. The second strategy, favoured by (...) prominent defenders of moral bioenhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I will argue that we ought to implement a combination of the second and third strategies. Furthermore, I will argue that the usual arguments against other instances of human enhancement do not apply to moral bioenhancement, or apply only to the first strategy, behavioural enhancement.

The enhancement of human traits has received academic attention for decades, but only recently has moral enhancement using biomedical means – moral bioenhancement (MB) – entered the discussion. After explaining why we ought to take the possibility of MB seriously, the paper considers the shape and content of moral improvement, addressing at some length a challenge presented by reasonable moral pluralism. The discussion then proceeds to this question: Assuming MB were safe, effective, and universally available, would it be morally desirable? (...) In particular, would it pose an unacceptable threat to human freedom? After defending a negative answer to the latter question – which requires an investigation into the nature and value of human freedom – and arguing that there is nothing inherently wrong with MB, the paper closes with reflections on what we should value in moral behaviour.

The Moral Psychology Handbook offers a survey of contemporary moral psychology, integrating evidence and argument from philosophy and the human sciences.

Now in a thoroughly revised and expanded third edition, this authoritative Handbook reviews current knowledge about all aspects of emotion and its role in human ...

Opponents of biomedical enhancement often claim that, even if such enhancement would benefit the enhanced, it would harm others. But this objection looks unpersuasive when the enhancement in question is a moral enhancement — an enhancement that will expectably leave the enhanced person with morally better motives than she had previously. In this article I (1) describe one type of psychological alteration that would plausibly qualify as a moral enhancement, (2) argue that we will, in the medium-term future, probably be (...) able to induce such alterations via biomedical intervention, and (3) defend future engagement in such moral enhancements against possible objections. My aim is to present this kind of moral enhancement as a counter-example to the view that biomedical enhancement is always morally impermissible. (shrink)

This text addresses the profound human questions of love and work. Beginning with a historical introduction, the author progresses through adaptive problems that humans face, and concludes by showing how evolutionary psychology encompasses all branches of psychology.

Unfit for the Future argues that the future of our species depends on radical enhancement of the moral aspects of our nature. Population growth and technological advances are threatening to undermine the conditions of worthwhile life on earth forever. We need to modify the biological bases of human motivation to deal with this challenge.

Evolutionary approaches to the emotions have traditionally focused on a subset of emotions that are shared with other species, characterized by distinct signals, and designed to solve a few key adaptive problems. By contrast, an evolutionary psychological approach (a) broadens the range of adaptive problems emotions have evolved to solve, (b) includes emotions that lack distinctive signals and are unique to humans, and (c) synthesizes an evolutionary approach with an information-processing perspective. On this view, emotions are superordinate mechanisms that evolved (...) to coordinate the activity of other programs in the solution of adaptive problems. We illustrate the heuristic value of this approach by furnishing novel hypotheses for disgust and sexual arousal and highlighting unexplored areas of research. (shrink)

Emotions can be explained as specialized states, shaped by natural selection, that increase fitness in specific situations. The physiological, psychological, and behavioral characteristics of a specific emotion can be analyzed as possible design features that increase the ability to cope with the threats and opportunities present in the corresponding situation. This approach to understanding the evolutionary functions of emotions is illustrated by the correspondence between (a) the subtypes of fear and the different kinds of threat; (b) the attributes of happiness (...) and sadness and the changes that would be advantageous in propitious and unpropitious situations; and (c) the social emotions and the adaptive challenges of reciprocity relationships. In addition to addressing a core theoretical problem shared by evolutionary and cognitive psychology, explicit formulations of the evolutionary functions of specific emotions are of practical importance for understanding and treating emotional disorders.

Can advances in neuroscience be harnessed to enhance human moral capacities? And if so, should they? De Grazia explores these questions in ‘Moral Enhancement, Freedom, and What We Value in Moral Behaviour’.1 Here, I offer a neuroscientist's perspective on the state of the art of moral bioenhancement, and highlight some of the practical challenges facing the development of moral bioenhancement technologies.The science of moral bioenhancement is in its infancy. Laboratory studies of human morality usually employ highly simplified models aimed at (...) measuring just one facet of a cognitive process that is relevant for morality. These studies have certainly deepened our understanding of the nature of moral behaviour, but it is important to avoid overstating the conclusions of any single study. De Grazia cites several purported examples of ‘non-traditional means of moral enhancement’, including one of my own studies. According to De Grazia, we showed that ‘selective serotonin reuptake inhibitors as a means to being less inclined to assault people’. In fact, our findings are a bit more subtle and nuanced than implied in the target article, as is often the case in neuroscientific studies of complex human behaviour. In our study, we tested the effects of the selective serotonin reuptake …. (shrink)

Some argue that humans should enhance their moral capacities by adopting institutions that facilitate morally good motives and behaviour. I have defended a parallel claim: that we could permissibly use biomedical technologies to enhance our moral capacities, for example by attenuating certain counter-moral emotions. John Harris has recently responded to my argument by raising three concerns about the direct modulation of emotions as a means to moral enhancement. He argues that such means will be relatively ineffective in bringing about moral (...) improvements, that direct modulation of emotions would invariably come at an unacceptable cost to our freedom, and that we might end up modulating emotions in ways that actually lead to moral decline. In this article I outline some counter-intuitive potential implications of Harris' claims. I then respond individually to his three concerns, arguing that they license only the very weak conclusion that moral enhancement via direct emotion modulation is sometimes impermissible. However I acknowledge that his third concern might, with further argument, be developed into a more troubling objection to such enhancements. (shrink)

We begin, in section 2, with a brief sketch of a cluster of assumptions about human desires, beliefs, actions, and motivation that are widely shared by historical and contemporary authors on both sides in the debate. With this as background, we’ll be able to offer a more sharply focused account of the debate. In section 3, our focus will be on links between evolutionary theory and the egoism/altruism debate. There is a substantial literature employing evolutionary theory on each side of (...) the issue. However, it is our contention that neither camp has offered a convincing case. We are much more sanguine about recent research on altruism in social psychology, which will be our topic in section 4. Though we don’t think this work has resolved the debate, we will argue that it has made illuminating progress – progress that philosophers interested in the question cannot afford to ignore.

abstract As history shows, some human beings are capable of acting very immorally. 1 Technological advance and consequent exponential growth in cognitive power means that even rare evil individuals can act with catastrophic effect. The advance of science makes biological, nuclear and other weapons of mass destruction easier and easier to fabricate and, thus, increases the probability that they will come into the hands of small terrorist groups and deranged individuals. Cognitive enhancement by means of drugs, implants and biological (including (...) genetic) interventions could thus accelerate the advance of science, or its application, and so increase the risk of the development or misuse of weapons of mass destruction. We argue that this is a reason which speaks against the desirability of cognitive enhancement, and the consequent speedier growth of knowledge, if it is not accompanied by an extensive moral enhancement of humankind. We review the possibilities for moral enhancement by biomedical and genetic means and conclude that, though it should be possible in principle, it is in practice probably distant. There is thus a reason not to support cognitive enhancement in the foreseeable future. However, we grant that there are also reasons in its favour, but we do not attempt to settle the balance between these reasons for and against. Rather, we conclude that if research into cognitive enhancement continues, as it is likely to, it must be accompanied by research into moral enhancement. (shrink)

Techniques for achieving moral enhancement will modify brain processes to produce what is alleged to be more moral conduct. Neurophilosophy and neuroethics must ponder what “moral enhancement” could possibly be, if possible at all. Objections to the very possibility of moral enhancement, raised from various philosophical and neuroscientific standpoints, fail to justify skepticism, but they do place serious constraints on the kinds of efficacious moral enhancers. While there won't be a “morality pill,” and hopes for global moral enlightenment will remain (...) hopes, there will be a large variety of behavioral modifiers described as enhancers of some aspect of morality or another according to prevailing social norms. The most likely moral enhancers that will be designed, tested, and marketed in the near future will attempt to alleviate seriously immoral and illegal behavior. Some enhancers diminishing antisocial conduct and a few designed to elevate moral conduct above normal levels will also become available, although their widespread use is doubtful. There will also be specialized modifications for enhancing whatever an individual personally regards as moral, and for enabling better performance by a person in an operational role. A measure of skepticism toward all the proposed kinds of moral enhancement is advised, and where political implementation of moral enhancers is concerned, a healthy amount of cynicism as well.

It is not the purpose of this article to evaluate the techno-scientific claims of the transhumanists. Instead, I question seriously the nature of the ethics and morals they claim can, or soon will, be manipulated artificially. I argue that while the possibility to manipulate human behavior via emotional processes exists, the question still remains concerning the content of morality. In other words, neural moral enhancement does not capture the fullness of human moral psychology, which includes moral capacity and moral content. (...) In this article, I revisit the debate between Hume and Kant concerning the role of emotions and reason in moral philosophy. I do so with reference to the work of philosopher Alasdair McIntyre. His moral philosophy has long stood as an essential text in virtue ethics, which constitutes the basis for my critique of the promise to engineer virtues (what I call “neural moral enhancement”). First, I outline three specific shifts that occurred in the history of Western moral philosophy in order to contextualize current debates on the nature of morality/moral agency. Second, I summarize MacIntyre's critique of contemporary moral philosophy and show its relevance to an assessment of neural moral enhancement. Finally I argue that moral neuroenhancement is a one-dimensional conceptualization of moral agency that does not reflect the fullness of human moral psychology. It envisions a world in which individual moral capacities will be enhanced and controlled but says nothing about the nature of the morality. (shrink)

We respond to a number of objections raised by John Harris in this journal to our argument that we should pursue genetic and other biological means of morally enhancing human beings (moral bioenhancement). We claim that human beings now have at their disposal means of wiping out life on Earth and that traditional methods of moral education are probably insufficient to achieve the moral enhancement required to ensure that this will not happen. Hence, we argue, moral bioenhancement should be sought (...) and applied. We argue that cognitive enhancement and technological progress raise acute problems because it is easier to harm than to benefit. We address objections to this argument. We also respond to objections that moral bioenhancement: (1) interferes with freedom; (2) cannot be made to target immoral dispositions precisely; (3) is redundant, since cognitive enhancement by itself suffices.
