Although transhumanism offers hope for the transcendence of human biological limitations, it generates many intrinsic and consequential ethical concerns. The latter include issues such as the exacerbation of social inequalities and the exponentially increasing technological capacity to cause harm. To mitigate these risks, many thinkers have initiated investigations into the possibility of moral enhancement that could limit the power disparities facilitated by biotechnological enhancement. The arguments often focus on whether moral enhancement is morally permissible, or even obligatory, and remain largely (...) in the realm of the hypothetical. This paper proposes that psilocybin may represent a viable, practical option for moral enhancement and that its further research in the context of moral psychology could comprise the next step in the development of moral transhumanism.

Asking whether transhumanist hopes of overcoming ageing and cognitive and other shortcomings are realistic, this paper pitches a Christian anthropology against a transhumanist anthropology. It is shown that on critical examination many of the technologies proposed by transhumanists in order to better or extend human life raise questions about dualism and materialism, about our nature as relational beings, and indeed even about what it means to be alive.

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a profound challenge to egalitarian (...) social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

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)

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.

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)

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

In recent years a number of biologists, anthropologists, and animal scientists have tried to explain the biological evolution of morality, and claim to have found the rudiments of morality in the altruistic behavior of our nearest nonhuman relatives. I argue that there is one feature of morality to which these accounts do not pay adequate attention: normative self-government, the capacity to be motivated to do something by the thought that you ought to do it. This is a feature of the (...) form of moral motivation rather than merely of its content, one that I believe we do not share with non-rational animals. Unlike his more recent followers, Darwin did try to explain how this capacity evolved. I explain Darwin's account and the way it drew on sentimentalist philosophy, and argue that such accounts are unsatisfactory. Drawing on the more radical accounts of the evolution of morality found in thinkers like Nietzsche and Freud, I speculate that moral motivation may have originated with the internalization of the dominance instincts, and sketch the beginnings of the path that the development of reason in both its theoretical and practical employments might have followed.

Selected by Christianity Today as one of the 100 most important books on religion of the twentieth century. Leading theological ethicist Stanley Hauerwas shows how discussions of Christology and the authority of scripture involve questions about what kind of community the church must be to rightly tell the stories of God. He challenges the dominant assumption of contemporary Christian social ethics that there is a special relation between Christianity and some form of liberal democratic social system.

According to the author of "After Virtue, " to flourish, humans need to develop virtues of independent thought and acknowledged social dependence. This book presents the moral philosopher's comparison of humans to other animals and his exploration of the impact of these virtues.

The timeless human desire to be more beautiful, intelligent, healthy, athletic, or young has given rise in our time to technologies of human enhancement. Athletes use drugs to increase their strength or stamina; cosmetic surgery is widely used to improve physical appearance; millions of men take drugs like Viagra to enhance sexual performance. And today researchers are exploring technologies such as cell regeneration and implantable devices that interact directly with the brain. Some condemn these developments as a new kind of (...) cheating -- not just in sports but in life itself -- promising rewards without effort and depriving us most of all of what it means to be authentic human beings. "Transhumanists," on the other hand, reject what they see as a rationalizing of human limits, as if being human means being content forever with underachieving bodies and brains. To be human, they insist, is to be restless with possibilities, always eager to transcend biological limits. As the debate grows in urgency, how should theology respond? Christian theologians recognize truth on both sides of the argument, pointing out how the yearnings of the transhumanists -- if not their technological methods -- find deep affinities in Christian belief. In this volume, Ronald Cole-Turner has joined seasoned scholars and younger, emerging voices together to bring fresh insight into the technologies that are already reshaping the future of Christian life and hope.

In his famous paper, Julian Huxley gives the outline of what he believes future humanity could – and should – look like. By pointing out the numerous limitations and feebleness the human nature is – at the time – prone to, and by confronting them with the possibilities humankind has, Huxley expresses the need to research and put into use all possible measures that would enable man achieve utmost perfection.

The human desire to acquire new capacities is as ancient as our species itself. We have always sought to expand the boundaries of our existence, be it socially, geographically, or mentally. There is a tendency in at least some individuals always to search for a way around every obstacle and limitation to human life and happiness.
