This collection focuses on questions that arise when morality is considered from the perspective of recent work on rational choice and evolution. Linking questions like "Is it rational to be moral?" to the evolution of cooperation in "The Prisoners Dilemma," the book brings together new work using models from game theory, evolutionary biology, and cognitive science, as well as from philosophical analysis. Among the contributors are leading figures in these fields, including David Gauthier, Paul M. Churchland, Brian Skyrms, Ronald de (...) Sousa, and Elliot Sober. (shrink)

It may seem that there is no need to review such a well-known book. This is the second edition of Peter Singer's text, Practical Ethics. The first edition has been widely used and influential; indeed for many it defines the field of applied ethics. The field is lucky; rarely is such popular work so carefully argued, so factually well informed and so well written. In addition, it is unusual for the author of a basic text to be so daring. (...) Peter Singer deserves credit for placing the interests of animals and famine victims on the agenda of applied ethics, and for making that agenda so prominent in public fora. But it behooves us to scrutinize carefully the power of definitive works as well. What sets the agenda is, for that very reason, more difficult to assess critically. (shrink)

This book explores the role of artificial intelligence in the development of a claim that morality is person-made and rational. Professor Danielson builds moral robots that do better than amoral competitors in a tournament of games like the Prisoners Dilemma and Chicken. The book thus engages in current controversies over the adequacy of the received theory of rational choice. It sides with Gauthier and McClennan, who extend the devices of rational choice to include moral constraint. Artificial Morality goes further, (...) by promoting communication, testing and copying of principles and by stressing empirical tests. (shrink)

A democratic ethics of biological technology must engage the public. This is not easy to do in a way that satisfies the demands of democratic ethics, or meets the pace of rapidly changing, complex technology. This paper describes a solution proposed by the University of British Columbia’s Norms Evolving in Response to Dilemmas interdisciplinary research group. The solution, the NERD web survey, has three distinct advantages over other methods: it is Deep—the survey provides deep data, particularly when compared to alternatives (...) such as polls and focus groups; Cheap—our survey is cost effective, which is important for a truly democratic tool; and Improvable—the NERD survey is a work in progress, improvable by design.

Background: Recent studies on public attitudes toward life extension technologies show a mix of ambivalence toward and support for extending the human lifespan. Attitudes toward genetic modification of organisms and technological enhancements may be used to categorize individuals according to political or ideological orientation such as technoprogressive or conservative and it could be easy to assume that these categories are related to more general categorizations related to culture, e.g. between Traditional and Secular-rational values in the World Values Survey. This paper (...) discusses how attitudes toward aspects of radical life extension may be related to cultural values as revealed in an online deliberative survey among university students conducted between January 2012 to January 2013. Survey results suggest that attitudes toward radical life extension tend to be mixed among groups categorized as Traditional, Secular-rational, Survivalist, and Self-expressionist. The study explored the relation between responses of 326 university students to 5 key questions on radical life extension and the cultural values they tend to favor as indicated by their response to 20 statements from the World Values Survey.Design and Method: The survey consisted of 3 stages: an online pre-discussion survey, face-to-face discussion, and post-discussion survey. After completing the 5 main survey questions in stage 1, participants were presented two additional questionnaires: one on cultural attitudes using 20 statements from the 2004-2008 World Values Survey and another on health attitudes with 12 statements from Dutta-Bergman’s 2004 study. In stage 2, participants were engaged in a face-to-face discussion in class focusing on their responses to the five key questions. After the discussion, they were invited to reconsider the choices and reasons they posted in stage 1 in the light of the face-to-face class discussion in stage 2.Results: Responses to the five survey questions showed that there tended to be more individuals across groups who disagreed with adopting technologies that radically extend the human lifespan beyond the current limit of 120 years. Attitudes toward radical life extension did not correspond to cultural attitudes indicated by responses to the WVS questions. The proportion of agreement/disagreement to statements presented in each of the five questions varied across cultural groups and there tended to be more individuals who disagreed with radical life extension in all groups. Changes in responses after the discussion stage were not significant and most respondents maintained their prior views.Discussion: Cultural attitudes associated with familiar technologies may not correspond with attitudes toward newer technologies since beliefs and values may need to be adapted to new imagined situations that the new technologies elicit. Moral understandings associated with familiar technological habits and beliefs are not necessarily carried over to new technologies. (shrink)

Rationality and evolution are apparently quite different, applying, respectively, to the acts of complex, well-informed individuals and to populations of what may be mindlessly simple entities. So it is remarkable that evolutionary game theory shows the theory of rational agents and that of populations of replicating strategies to be isomorphic. Danielson illustrates its main concepts—evolutionarily stable strategies and replicator dynamics—with simple models that apply to biological and social interactions; and he distinguishes biological, economic, and generalist ways of interpreting the (...) theory. Against the background of isomorphism, he considers three ways in which evolution and rationality differ and how two-level models may combine them. He concludes with a survey of the normative significance of the unification of rationality and evolutionary game theory and some speculation about the evolution of human rationality. (shrink)

Behavioral science, unified in the way Gintis proposes, should affect ethics, which also finds itself in “disarray,” in three ways. First, it raises the standards. Second, it removes the easy targets of economic and sociobiological selfishness. Third, it provides methods, in particular the close coupling of theory and experiments, to construct a better ethics.

Morality is serious yet it needs to be reconciled with the free play of alternatives that characterizes rational and ethical agency. Beginning with a sketch of the seriousness of morality modeled as a constraint, this paper introduces a technical conception of play as degrees of freedom. We consider two ways to apply game theory to ethics, rationalist and evolutionary game theory, contrasting the way they model moral constraint. Freedom in the rationalist account is problematic, subverting willful commitment. In the evolutionary (...) account, freedom is also problematic, leading to an infinity of possible social norms with dubious normative force. While these two approaches complement each other, we argue that the evolutionary approach is superior on both theoretical and practical grounds. (shrink)

We advocate and share the same theoretical framework for empirical research in ethics as exemplified in Christina Bicchieri’s The Grammar of Society. Our research differs from Bicchieri’s in our approach to experimentation: where she relies on lab experiments, we have constructed an experimental platform based on an internet survey instrument; where she relies on rational reconstructions, we do not. In this paper we focus on four contrasts in our methods: (1) we provide a space to explore ethical influence and norm (...) transmission between participants, belief and choice revision, and reputation over time; (2) we provide ways for participants to expand the context of their and others’ decisions; (3) we focus on more realistic ethical decisions than is allowed by games; and (4) we explain why Bicchieri’s method of rational reconstructions presents challenges to her theory of social norms. Our methods are complementary to Bicchieri’s, and together we can work toward developing more comprehensive empirically informed ethics. †To contact the authors, please write to Peter Danielson, W.

Using a simple learning agent, we show that learning self-control in the primrose path experiment does parallel learning cooperation in the prisoner's dilemma. But Rachlin's claim that “there is no essential difference between self-control and altruism” is too strong. Only iterated prisoner's dilemmas played against reciprocators are reduced to self-control problems. There is more to cooperation than self-control and even altruism in a strong sense.

Emerging technologies like robotics for war and peace stress our moral norms and generate much public interest and controversy. We use this interest to attract participants to an innovative on-line survey platform, designed for experimenting with public engagement in the ethics of technology. In particular, the N-Reasons platform addresses several issues in democratic ethics: the cost of public participation, the methodological issue of feasible reflective ethical equilibrium (how can individuals in a large group, take into account the ethical views of (...) all others?), and the reliability of public participation processes. We sketch the motivation and design of the N-Reasons platform, stressing the need for a practical (fast, low-cost) instrument that makes equilibrium feasible. We focus on the Robot Ethics Survey that featured a set of nine ethical challenges raised by robotics for war and peace. Over 400 people in five disjoint groups participated in this on-line survey experiment. We analyze the results, both quantitatively and qualitatively, the participants’ decisions taken and the reasons supporting these decisions. Both decisions and reasons strongly distinguished lethal military robotics from peace-related robotics. Methodologically, both decisions and reasons over five distinct groups were remarkably consistent. (shrink)

Is game theory good for us? This may seem an odd question. In the strict sense, game theory—the axiomatic account of interaction between rational agents—is as morally neutral as arithmetic. But the popularization of game theory as a way of thinking about social interaction is far from neutral. Consider the contrast between characterizing bargaining over distribution as a “zero-sum society” and focussing on “win-win” cooperative solutions. These reflections bring us to the book under review, Prisoner's Dilemma, a popular introduction to (...) game theory and its relation to ethics by the respected science writer William Poundstone. The book begins with a moral dilemma and ends by discussing the evolution of co-operation. Poundstone emphasizes—correctly, to my mind—the ethical potential of game theory. He concludes his first chapter with this striking claim: “Today's practitioners of game theory are attempting to forge a kind of ethical progress. Is there any way to promote the common good in a prisoner's dilemma? The attempt to answer this question is one of the great intellectual adventures of our time”. (shrink)

N-Reasons is an experimental Internet survey platform designed to enhance public participation in applied ethics and policy. N-Reasons encourages individuals to generate reasons to support their judgments, and groups to converge on a common set of reasons pro and con various issues. In the Robot Ethics Survey some of the reasons contributed surprising judgments about autonomous machines. Presented with a version of the trolley problem with an autonomous train as the agent, participants gave unexpected answers, revealing high expectations for the (...) autonomous machine and shifting blame from the automated device to the humans in the scenario. Further experiments with a standard pair of human-only trolley problems refine these results. While showing the high expectations even when no autonomous machine is involved, human bystanders are only blamed in the machine case. A third experiment explicitly aimed at responsibility for driverless cars confirms our findings about shifting blame in the case of autonomous machine agents. We conclude methodologically that both results point to the power of an experimental survey based approach to public participation to explore surprising assumptions and judgments in applied ethics. However, both results also support using caution when interpreting survey results in ethics, demonstrating the importance of qualitative data to provide further context for evaluating judgments revealed by surveys. On the ethics side, the result about shifting blame to humans interacting with autonomous machines suggests caution about the unintended consequences of intuitive principles requiring human responsibility.

We can learn about human ethics from machines. We discuss the design of a working machine for making ethical decisions, the N-Reasons platform, applied to the ethics of robots. This N-Reasons platform builds on web based surveys and experiments, to enable participants to make better ethical decisions. Their decisions are better than our existing surveys in three ways. First, they are social decisions supported by reasons. Second, these results are based on weaker premises, as no exogenous expertise (aside from that (...) provided by the participants) is needed to seed the survey. Third, N-Reasons is designed to support experiments so we can learn how to improve the platform. We sketch experimental results that show the platform is a success as well as pointing to ways it can be improved. (shrink)

V.1 Re-establishing an initial union among philosophy, science, and wisdom by recovering our understanding of philosophy, science : how philosophy, science, is, and always has been, chiefly a study of the one and the many -- v.2. An introduction to ragamuffin Thomism.

This book challenges the presupposition among professional philosophers that René Descartes is the Father of Modern Philosophy. It demonstrates by intensive textual analysis of Descartes's Discourse and Meditations that he inaugurated a new type of sophistry rather than a new way of conducting philosophy. Transcendental Sophistry is a synthesis of Renaissance humanism and Christian theology, especially the theology of creation. This striking re-evaluation of the achievement of Descartes opens the history of Western philosophy to radical reinterpretation.

Peter Kwasniewski shows that St. Thomas contemplates the nature of ecstasy at key stages in the development of his thought and that it plays a crucial role in his doctrine of love. St. Thomas recognized that all love involves ecstatic transcendence, whether it be the creature's self-oblation to the Creator, the reverence of an inferior for a superior, a superior's generosity toward an inferior, or the mutual affection and help of equals joined in friendship. Love of persons for their (...) own sake generates an ecstatic love in which the self is borne as a gift to another subject by sharing a common life aspiring to common goods. Kwasniewski also examines Aquinas on the question of whether or not God experiences ecstasy, and if so, in what ways. (shrink)

In the process of so doing, this work demonstrates how the skill of prudential living is a necessary condition for becoming a grand master of (...) leadership in any and every profession. (shrink)

Emerging neuroscientific insights are changing our understanding of what it means to be human. The resulting reconceptualization continues to impact law and the fit between law and morality. This book takes account of those developments and suggests that normative theory, particularly in its non-instrumental iterations, will be challenged, most profoundly. If we are, as the science suggests, nothing more than the coincidence of mechanical forces, then law and normative theory that depend on the immaterial and that would draw distinctions between (...) the "mental" or "emotional" and the more manifestly physical are misguided, so misguided that they would actually undermine human thriving. Indeed, they already do. The ramifications of that conclusion are profound. Trialectic posits and investigates the impact of those ramifications on law. (shrink)

Scientists engaged in global health research are increasingly faced with barriers to access and use of human tissues from the developing world communities where much of their research is targeted. In part, the problem can be traced to distrust of researchers from affluent countries, given the history of 'scientific-imperialism' and 'biocolonialism' reflected in past well publicized cases of exploitation of research participants from low to middle income countries. To a considerable extent, the failure to adequately engage host communities, the opacity (...) of informed consent, and the lack of fair benefit-sharing have played a significant role in eroding trust. These ethical considerations are central to biomedical research in low to middle income countries and failure to attend to them can inadvertently contribute to exploitation and erode trust. A 'tissue trust' may be a plausible means for enabling access to human tissues for research in a manner that is responsive to the ethical challenges considered. Preventing exploitation and restoring trust while simultaneously promoting global health research calls for innovative approaches to human tissues research. A tissue trust can reduce the risk of exploitation and promote host capacity as a key benefit. (shrink)

In this paper I sketch an account of moral blame and blameworthiness. I begin by clarifying what I take blame to be and explaining how blameworthiness is to be analyzed in terms of it. I then consider different accounts of the conditions of blameworthiness and, in the end, settle on one according to which a person is blameworthy for φ-ing just in case, in φ-ing, she violates one of a particular class of moral requirements governing the attitudes we bear, and (...) our mental orientation, toward people and other objects of significant moral worth. These requirements embody the moral stricture that we accord to these others a sufficient level of respect, one that their moral worth demands. This is a familiar theme which has its roots in P. F. Strawson’s pioneering views on moral responsibility. My development of it leads me to the conclusion that acting wrongly is not a condition of blameworthiness: violating a moral requirement to perform, or refrain from performing, an action is neither necessary nor sufficient for being blameworthy. All we are ever blameworthy for, I will argue, are certain aspects of our mental bearing toward others. We can be said to be blameworthy for our actions only derivatively, in the sense that those actions are the natural manifestations of the things for which we are strictly speaking blameworthy.

Many of us are inclined to accept something like the following principle: We can only be properly morally assessed for what is in our control. And yet our ordinary practices seem to frequently violate this principle. The resulting tension, and the attempt to resolve it, is the problem of moral luck. For example, we tend to punish and think worse of the negligent driver who kills a child than we do the equally negligent driver who was lucky there was no (...) child in his path. Thus, the lucky outcomes of our actions do seem to affect the extent to which we hold and are held responsible, but these are not things over which we exercise control. And, as Thomas Nagel famously illustrated in his response to Bernard Williams (the two of which papers form the founding documents of the moral luck debate), the influence of luck is not limited to outcomes. For the circumstances in which we find ourselves and, indeed, our very constitution are also shaped by luck. Since the publication of Williams's and Nagel's papers, the existence and breadth of moral luck has been hotly debated. This debate is not a mere intellectual trifle but, as the essays in this volume illustrate, a debate which lies at the heart of free will, responsibility, identity, causation, and self-creation.

There is a debate in normative ethics about whether or not our moral obligations depend solely on either our evidence concerning, or our beliefs about, the world. Subjectivists maintain that they do and objectivists maintain that they do not. I shall offer some arguments in support of objectivism and respond to the strongest argument for subjectivism. I shall also briefly consider the significance of my discussion to the debate over whether one’s future voluntary actions are relevant to one’s current moral (...) obligations. (shrink)

We study the proof-theoretic strength and effective content of the infinite form of Ramsey's theorem for pairs. Let RT n k denote Ramsey's theorem for k-colorings of n-element sets, and let RT $^n_{ denote (∀ k)RT n k . Our main result on computability is: For any n ≥ 2 and any computable (recursive) k-coloring of the n-element sets of natural numbers, there is an infinite homogeneous set X with X'' ≤ T 0 (n) . Let IΣ n and BΣ (...) n denote the Σ n induction and bounding schemes, respectively. Adapting the case n = 2 of the above result (where X is low 2 ) to models of arithmetic enables us to show that RCA 0 + IΣ 2 + RT 2 2 is conservative over RCA 0 + IΣ 2 for Π 1 1 statements and that $RCA_0 + I\Sigma_3 + RT^2_{ , is Π 1 1 -conservative over RCA 0 + IΣ 3 . It follows that RCA 0 + RT 2 2 does not imply BΣ 3 . In contrast, J. Hirst showed that $RCA_0 + RT^2_{ does imply BΣ 3 , and we include a proof of a slightly strengthened version of this result. It follows that $RT^2_{ is strictly stronger than RT 2 2 over RCA 0. (shrink)

David Lewis has offered a reply to the standard argument for the claim that the truth of determinism is incompatible with anyone’s being able to do otherwise than she in fact does. Helen Beebee has argued that Lewis’s compatibilist strategy is untenable. In this paper I show that one recent attempt to defend Lewis’s view against this argument fails and then go on to offer my own defense of Lewis’s view.
