What role should the physician's conscience play in the practice of medicine? Much controversy has surrounded the question, yet little attention has been paid to the possibility that disputants are operating with contrasting definitions of the conscience. To illustrate this divergence, we contrast definitions stemming from Abrahamic religions and those stemming from secular moral tradition. Clear differences emerge regarding what the term conscience conveys, how the conscience should be informed, and what the consequences are for violating one's conscience. Importantly, these (...) basic disagreements underlie current controversies regarding the role of the clinician's conscience in the practice of medicine. Consequently participants in ongoing debates would do well to specify their definitions of the conscience and the reasons for and implications of those definitions. This specification would allow participants to advance a more philosophically and theologically robust conversation about the means and ends of medicine. (shrink)

Elizabeth Fenton has criticised an earlier article by the authors in which the claim was made that, by providing humankind with means of causing its destruction, the advance of science and technology has put it in a perilous condition that might take the development of genetic or biomedical techniques of moral enhancement to get out of. The development of these techniques would, however, require further scientific advances, thus forcing humanity deeper into the danger zone created by modern science. Fenton argues (...) that the benefits of scientific advances are undervalued. The authors believe that the argument rather relies upon attaching a special weight to even very slight risks of major catastrophes, and attempt to vindicate this weighting. (shrink)

This paper identifies human enhancement as one of the most significant areas of bioethical interest in the last twenty years. It discusses in more detail one area, namely moral enhancement, which is generating significant contemporary interest. The author argues that so far from being susceptible to new forms of high tech manipulation, either genetic, chemical, surgical or neurological, the only reliable methods of moral enhancement, either now or for the foreseeable future, are either those that have been in human and (...) animal use for millennia, namely socialization, education and parental supervision or those high tech methods that are general in their application. By that is meant those forms of cognitive enhancement that operate across a wide range of cognitive abilities and do not target specifically ‘ethical’ capacities. The paper analyses the work of some of the leading contemporary advocates of moral enhancement and finds that in so far as they identify moral qualities or moral emotions for enhancement they have little prospect of success.

Ingmar Persson and Julian Savulescu argue that non-traditional forms of cognitive enhancement (those involving genetic engineering or pharmaceuticals) present a serious threat to humanity, since the fruits of such enhancement, accelerated scientific progress, will give the morally corrupt minority of humanity new and more effective ways to cause great harm. And yet it is scientific progress, accelerated by non-traditional cognitive enhancement, which could allow us to dramatically morally enhance human beings, thereby eliminating, or at least reducing, the threat from the (...) morally corrupt minority. I argue that this apparently intractable dilemma is less difficult to resolve than Persson and Savulescu suppose. Their analysis of non-traditional cognitive enhancement overstates the risks and undervalues the benefits that such enhancement might provide. Once the benefits are better described, it is clear that non-traditional cognitive enhancement could be the means of our survival, not of our destruction. (shrink)

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.
