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)

This article explores the respective roles that medical and technological cognitive enhancements, on the one hand, and the moral and epistemic virtues traditionally understood, on the other, can play in enabling us to lead the good life. It will be shown that neither the virtues nor cognitive enhancements (of the kind we have access to today or in the foreseeable future) on their own are likely to enable most people to lead the good life. While the moral and epistemic virtues (...) quite plausibly are both necessary and sufficient for the good life in theory, virtue ethics is often criticised for being elitist and unachievable in practice for the vast majority. Some cognitive enhancements, on the other hand, might be necessary for the good life but are far from sufficient for such an existence. Here it will be proposed that a combination of virtue and some cognitive enhancements is preferable. (shrink)

The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (shrink)

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

Educational neutrality states that decisions about school curricula and instruction should be made independently of particular comprehensive doctrines. Many political philosophers of education reject this view in favor of some non-neutral alternative. Contrary to what one might expect, some prominent liberal neutralists have also rejected this view in parts of their work. This paper has two purposes. The first part of the paper concerns the relationship between liberal neutrality and educational neutrality. I examine arguments by Rawls and Nagel and argue (...) that some of the same arguments they use to justify liberal neutrality also justify educational neutrality; thus, if we accept these arguments for liberal neutrality, we should also accept educational neutrality. The second part of the paper defends educational neutrality against objections that it is impossible and objections that it is undesirable. (shrink)

Instead of arguing about whether moral judgments are based on emotion or reason, moral psychologists should investigate the reliability of moral judgments by checking rates of framing effects in different kinds of moral judgments under different conditions by different people.

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)

Opponents of biomedical enhancement frequently adopt what Allen Buchanan has called the “Personal Goods Assumption.” On this assumption, the benefits of biomedical enhancement will accrue primarily to those individuals who undergo enhancements, not to wider society. Buchanan has argued that biomedical enhancements might in fact have substantial social benefits by increasing productivity. We outline another way in which enhancements might benefit wider society: by augmenting civic virtue and thus improving the functioning of our political communities. We thus directly confront critics (...) of biomedical enhancement who argue that it will lead to a loss of social cohesion and a breakdown in political life. (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.

Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done (...) by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent than rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. (shrink)

In this paper1 I shall present not just the conscience of Huckleberry Finn but two others as well. One of them is the conscience of Heinrich Himmler. He became a Nazi in 1923; he served drably and quietly, but well, and was rewarded with increasing responsibility and power. At the peak of his career he held many offices and commands, of which the most powerful was that of leader of the S.S. - the principal police force of the Nazi regime. (...) In this capacity, Himmler commanded the whole concentration-camp system, and was responsible for the execution of the so-called ‘final solution of the Jewish problem’. It is important for my purposes that this piece of social engineering should be thought of not abstractly but in concrete terms of Jewish families being marched to what they think are bath-houses, to the accompaniment of loud-speaker renditions of extracts from The Merry Widow and Tales of Hoffman, there to be choked to death by poisonous gases. Altogether, Himmler succeeded in murdering about four and a half million of them, as well as several million gentiles, mainly Poles and Russians. The other conscience to be discussed is that of the Calvinist theologian and philosopher Jonathan Edwards. He lived in the first half of the eighteenth century, and has a good claim to be considered America’s first serious and considerable philosophical thinker. He was for many years a widely-renowned preacher and Congregationalist minister in New England; in 1748 a dispute with his congregation led him to resign (he couldn’t accept their view that unbelievers should be admitted to the Lord’s Supper in the hope that it would convert them); for some years after that he worked as a missionary, preaching to Indians through an interpreter;, then in 1758 he accepted the presidency of what is now Princeton University, and within two months died from a smallpox inoculation. Along the way he wrote some first-rate philosophy: his book attacking the notion of free will is still sometimes read.. (shrink)

Building on the strengths of the first edition, the second edition of the Irwin Nicomachean Ethics features a revised translation (with little editorial intervention), expanded notes (including a summary of the argument of each chapter), an expanded Introduction, and a revised glossary.

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

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.

This note argues that a belief is knowledge if it's true, certain (i.e. a full belief) and obtained by a reliable process.

Groups do better at reasoning tasks than individuals, and, in some cases, do even better than any of their individual members. Here is an illustration. In the standard version of Wason selection task (Wason, 1966), the most commonly studied problem in the psychology of reasoning, only about 10% of participants give the correct solution, even though it can be arrived at by elementary deductive reasoning.1 Such poor performance begs for an explanation, and a great many have been offered. What makes (...) the selection task relevant here is that the difference between individual and group performance is striking. Moshman & Geil for instance (1998, see also Maciejovsky & Budescu, 2007) had participants try and resolve the task either individually or in groups of five or six participants. While, unsurprisingly, only 9% of the participants working on their own found the correct solution, an astonishing 70% of the groups did. Moreover, when groups were formed with participants who had first tried to solve the task individually, 80% of the groups succeeded, including 30% of the groups in which none of the members had succeeded on his or her own. How are such differences between individual and group performance to be explained? (shrink)

I argue that political liberals should not support the monopoly of a single educational approach in state sponsored schools. Instead, they should allow reasonable citizens latitude to choose the worldview in which their own children are educated. I begin by defending a particular conception of political liberalism, and its associated requirement of public reason, against the received interpretation. I argue that the values of respect and civic friendship that motivate the public reason requirement do not support the common demand that (...) citizens “bracket” their comprehensive commitments in politics. Rather, citizens should seek to enact policies the justification of which is compatible with the truth of their fellow reasonable citizens’ worldviews. Next I argue that no single educational approach can meet this standard of justification. Many believe that state sponsored education in a pluralist, liberal society ought to present multiple worldviews in a neutral way. I argue that this aspiration is unrealizable, and no other educational model will plausibly meet the justificatory demand. Finally, I address two objections to my favored alternative: that it may allow for the inculcation of disrespect, and that it violates children’s autonomy. Against the first, I claim that political liberals have no grounds for thinking that reasonable citizens will seek to inculcate disrespect. Finally, I argue that there is no conception of autonomy that can sustain the second. (shrink)
