This volume gives an overview of the rising field of Experimental Ethics. It is organized into five main parts: PART I – Introduction: An Experimental Philosophy of Ethics? // PART II – Applied Experimental Ethics: Case studies // PART III – On Methodology // PART IV – Critical Reflections // PART V – Future Perspectives. Among the contributors: Walter Sinnott-Armstrong, Eric Schwitzgebel, Ezio di Nucci, Jacob Rosenthal, and Fernando Aguiar.

Recent years have seen a continual rise of interest in the empirical study of questions traditionally located in moral philosophy, i.e., studies in Experimental Ethics. In this chapter we briefly outline the recent history of this field. To do so we have to cross disciplinary borders to quite some extent. Tracing the beginnings of Experimental Ethics back to early works in moral psychology, we delineate a sequence of theories which eventually flow into current Experimental Ethics. We then briefly review four (...) topics which are intensively investigated in Experimental Ethics at the moment: moral relativism, individual and cross-cultural differences in moral judgment, and interactions of moral evaluation with other philosophical concepts. We conclude with a short historically informed comment on the demarcation problem of Experimental Ethics. (shrink)

L'" action " est aujourd'hui un concept clé de la philosophie et de la plupart des sciences humaines. Dans toutes ces disciplines (économie, psychologie, sociologie), la formulation d'une " théorie de l'action " constitue l'un des principaux centres d'intérêt de la réflexion théorique. Ce livre développe une idée centrale : aux deux modèles dominants de l'action rationnelle et de l'action à visée normative, il est possible d'en ajouter un troisième, qui insiste sur le caractère créatif de l'agir humain. Ce troisième (...) modèle doit avoir une position englobante par rapport aux deux premiers. Il s'agit de mettre au jour dans tout agir humain une dimension créative qui n'est pas suffisamment prise en compte dans les modèles théoriques de l'action rationnelle et de l'action à visée normative. Cette approche, en effet, n'oppose pas aux actes créatifs les actes non créatifs, mais cherche à préciser les conditions d'application des deux modèles courants, en mettant en évidence la dimension créatrice qui s'y trouve implicitement contenue. Les différentes parties de l'ouvrage (étude de l'histoire des idées, reconstruction théorique des concepts, leur application concrète) servent toutes un but commun : montrer qu'il est pertinent et nécessaire de prendre en considération le caractère créateur de l'agir humain.

The article deals with the relationship between science and religion (esp. Christian faith) in two articles of physicists Max Planck and Pascual Jordan. The relationship of the two factors is reflected in the treatment of time, a subject that comes up because both articles were written on the occasion of the year's end or even the end of a decade. By analysing the two perspectives on time it is possible to distil the distinctive ideas of Planck and Jordan on religion (...) and how a religious should be related to a scientific world view. From this two different models of a positive relationship of science and religion can be formulated which transcend the framework of present discussions on the subject. In conclusion a possible role of science of religions in the dialogue between science and religion is described. (shrink)

Although humans qualify as one of the most cooperative animal species, the scale of violent intergroup conflict among them is unparalleled. Explanations of the underlying motivations to participate in an intergroup conflict, however, remain unsatisfactory. While previous research shows that intergroup conflict increases individually costly behavior to the benefit of the in-group, it has failed to identify robust triggers of aggressive behavior directed at out-groups. Here, we present a controlled laboratory experiment which demonstrates that such aggression can be provoked systematically (...) by manipulating the extent to which the own group is perceived to be on the offensive or the defensive side of a conflict. We find direct and causal evidence that the motivation to protect the in-group is not only a predictor of retaliatory aggression, but also promotes preemptive offensive actions against out-groups if they pose a potential threat. This finding improves our understanding of the escalation of intergroup conflicts and may have important implications for their prevention, as we find in our experiment that removing out-group threat substantially reduced intergroup aggression and led to full peace.

Although humans qualify as one of the most cooperative animal species, the scale of violent intergroup conflict among them is unparalleled. Explanations of the underlying motivation to participate in an intergroup conflict, however, remain unsatisfactory. While previous research shows that intergroup conflict increases ‘in-group love’, it fails to identify robust triggers of ‘out-group hate’. Here, we present a controlled laboratory experiment, which demonstrates that ‘out-group hate’ can be provoked systematically. We find direct and causal evidence that the intention to protect (...) the in-group is not only a crucial motivator of ‘out-group hate’ in defensive reactions, but also promotes preemptive offensive actions against out-group threat. Hence, the strength of ‘out-group hate’ depends on whether the own group is perceived to be on the offensive or the defensive side of the conflict. This finding improves our understanding of the escalation of intergroup conflicts and may have important implications for their prevention, as we find in our experiment that removing out-group threat substantially reduces intergroup aggression, leading to full peace.

In evolutionary models of indirect reciprocity, reputation mechanisms can stabilize cooperation even in severe cooperation problems like the prisoner’s dilemma. Under certain circumstances, conditionally cooperative strategies, which cooperate iff their partner has a good reputation, cannot be invaded by any other strategy that conditions behavior only on own and partner reputation. The first point of this paper is to show that an evolutionary version of backward induction can lead to a breakdown of this kind of indirectly reciprocal cooperation. Backward induction, (...) however, requires strategies that count and then cease to cooperate in the last, last but one, last but two, … game they play. These strategies are unlikely to exist in natural settings. We then present two new findings. (1) Surprisingly, the same kind of breakdown is also possible without counting. Strategies using rare golden opportunities for defection can invade conditional cooperators. This can create further golden opportunities, inviting the next wave of opportunists, and so on, until cooperation breaks down completely. (2) Cooperation can be stabilized against these opportunists, by letting an individual’s initial reputation be inherited from that individual’s parent. This ‘inclusive reputation’ mechanism can cope with any observably opportunistic strategy. Offspring of opportunists who successfully exploited a conditional cooperator cannot repeat their parents’ success because they inherit a bad reputation, which forewarns conditional cooperators in later generations.

Si la " critique philosophique de l'art " peut constituer l'axe central d'une approche de la pensée de Walter Benjamin, c'est d'abord parce que l'art représente l'élément par lequel l'homme accède à sa propre temporalité. Le passé individuel, l'origine commune, le projet militant se cristallisent dans le geste artistique. La mémoire elle-même est une forme d'art, non moins que l'anticipation d'un avenir désirable. Investi du pouvoir de définir ainsi l'humanité de l'homme, l'art devient éminemment critiquable : Benjamin n'a jamais cru (...) que pratiquer la " critique " dispensât d'être philosophe. La critique, au contraire, n'a d'autre lieu que la philosophie, sous sa forme la plus épurée. On touche ici du doigt le fascinant pouvoir intégrateur de la pensée benjaminienne, capable de conjuguer l'autobiographique et le politique, la précision analytique et l'élan éthique, la déconstruction et la métaphysique. Quand Benjamin a été si souvent morcelé en personnalités contradictoires, sous la plume parfois d'un seul et même commentateur, c'est une image très cohérente, très homogène, qui nous semble ressortir des diverses contributions de ce recueil.

In this paper it is asked whether it is meaningful to state a ‘right to work’ as a basic human right to be written down in the constitution, for example, whether working time should generally be reduced, and whether those who do not have (or find) a job should get a guaranteed minimal income. All three demands have to be rejected, at least in the radical form in which they are often stated. They cannot be realised at all or at (...) least not without impairing other basic human rights. Finally, it is asked what can be retained from these (usually well-intended) demands. (shrink)

First, the role of markets as co-ordination mechanisms and, more generally, the role of exchange relations in a society is discussed. We consider illegal markets as well as markets where transactions are performed not using money but some other exchange medium. Secondly, we ask for the political possibilities to intervene into such markets. Finally, we discuss the increasing,economising of social relations' and possible reasons for it.

I first discuss two aspects of a social order and cooperation which might be of high relevance: the problem of a spontaneous emerging of a social order, and the relation between exchange and cooperation. In doing so, I also discuss the role of production in separating areas of cooperation from those of competition. Second, I look more closely at the motivations for cooperative behaviour. It is argued that of the four kinds of motivation mentioned by Leist only two, self-interest and (...) altruism, are really necessary to explain cooperation. (shrink)

The article starts out with a sketch of the model of Individual behaviour, basic for modern economic theory, including the consideration of typical criticisms. The model then is examined in its application first to micro- and macroeconomic theorizing, then to the economic analysis of politics and of law. It concludes by pointing out some drawbacks inherent in the economic approach to the social sciences: economic imperialism, conservativism and the illusion of manageability.

First it is shown that in order to function well markets depend on some preconditions even if there are no external effects and there is complete information. One of these conditions is that individuals follow some moral norms. Then it is asked whether these norms are non-consequentialist. There might be some norms for which no consequentialist foundation can be constructed. However, these are not the norms which have to be followed in order that a market system functions well. Such norm-following-behaviour (...) can successfully be analysed with the economic model of behaviour, if the motivational assumption of this model is not artificially restricted to consider only financial incentives. Finally it is pointed to the fact that it is reasonable to employ the economic model of behaviour not only for analysing social processes but also for developing policy recommendations. (shrink)

After a short description of the economic model of behaviour it is shown that there are two reasons why problems arise if this model is applied to political processes and decisions. First, such decisions are often ‘low cost’, i.e. ‘wrong’ decisions have hardly any impact on the decision maker. Second, the behaviour of single individuals or small groups of individuals is to be explained. The common root of this problem is the difficulty to predict behaviour which is mainly preference governed (...) and not guided by (changing) restrictions. Nevertheless, this should not lead to abolish the economic model because (i) it can be usefully applied also in this area and (ii) a better alternative is hardly available. (shrink)

Drawing on an idea proposed by Darwin, it has recently been hypothesised that violent intergroup conflict might have played a substantial role in the evolution of human cooperativeness and altruism. The central notion of this argument, dubbed ‘parochial altruism’, is that the two genetic or cultural traits, aggressiveness against out-groups and cooperativeness towards the in-group, including self-sacrificial altruistic behaviour, might have coevolved in humans. This review assesses the explanatory power of current theories of ‘parochial altruism’. After a brief synopsis of (...) the existing literature, two pitfalls in the interpretation of the most widely used models are discussed: potential direct benefits and high relatedness between group members implicitly induced by assumptions about conflict structure and frequency. Then, a number of simplifying assumptions made in the construction of these models are pointed out which currently limit their explanatory power. Next, relevant empirical evidence from several disciplines which could guide future theoretical extensions is reviewed. Finally, selected alternative accounts of evolutionary links between intergroup conflict and intragroup cooperation are briefly discussed which could be integrated with parochial altruism in the future.

Building on and partially refining previous theoretical work, this paper presents an extended simulation model of ancestral warfare. This model (1) disentangles attack and defense, (2) tries to differentiate more strictly between selfish and altruistic efforts during war, (3) incorporates risk aversion and deterrence, and (4) pays special attention to the role of brutality. Modeling refinements and simulation results yield a differentiated picture of possible evolutionary dynamics. The main observations are: (i) Altruism in this model is more likely to evolve (...) for defenses than for attacks. (ii) Risk aversion, deterrence and the interplay of migration levels and brutality can change evolutionary dynamics substantially. (iii) Unexpectedly, one occasional simulation outcome is a dynamically stable state of ‘tolerated intergroup theft’, raising the question if corresponding patterns also exist in real intergroup conflicts. Finally, possible implications for theories of the co-evolution of bellicosity and altruism in humans are discussed. (shrink)

In diesem Artikel stellen wir die Evolutionäre Erkenntnistheorie kurz vor. Wir gehen dazu in zwei Schritten vor: In Schritt 1 charakterisieren wir die Evolutionäre Erkenntnistheorie anhand ihrer Antworten auf die Grundfragen an jede Erkenntnistheorie. In Schritt 2 stellen wir all jene philosophischen Positionen dar, mit denen die Evolutionäre Erkenntnistheorie eng verbunden ist.

It has recently been proposed that the evolution of human cooperativeness might, at least in part, have started as the cooptation of behavioral strategies evolved for solving problems of coordination to solve problems with higher incentives to defect, i.e. problems of cooperation. Following this line of thought, we systematically tested human subjects for spillover effects from simple coordination tasks (2x2 Stag Hunt games, SH) to problems of cooperation (2x2 Prisoner’s Dilemma games, PD) in a laboratory experiment with rigorous controls to (...) rule out subject confusion or habituation. Supporting the hypothesis that decision mechanisms for cooperation problems are linked with decision mechanisms for coordination, our main finding is that cooperation levels in PD games embedded in a sequence of SH games were significantly increased compared to a baseline sequence consisting only of PDs when subjects played in fixed pairs. No such effects could be found when players were randomly rematched each round. Additional findings include that this spillover effect cannot prevent a decay of cooperation over time, that there is no indication of a reversed effect, i.e. no signs of negative spillovers from failed cooperation to miscoordination, and that subjects self-reported preferences in SH games are prosocial.

ObjectivesConstant Installation of Present Orientation and Safety is a Eye Movements Desensitization and Reprocessing -derived technique, which is often used to prepare for the treatment of post-traumatic stress disorder. It differs from the latter by involving cyclically recurring exercises in reorientation to the present, interspersed between brief periods of exposure to the traumatic material.While EMDR is well established as a therapeutic method, the efficacy and mechanisms of action of CIPOS have not been investigated so far. In this pilot study, an (...) experimental setting was used to record the subjective and physiological effects of the CIPOS intervention compared to a control condition with pure mental exposition.MethodsThe study was performed on 30 healthy volunteers aged from 20 to 30 years. Distress was induced using audio files of subjectively stressful situations. Subjective distress was measured via the Subjective Units of Distress Scale, while physiological indicators were used as measures for objective stress. For each condition, pre- and post-intervention comparisons were calculated.ResultsIn both groups, startle reflex potentiation and mean skin conductance level significantly decreased. In the group with CIPOS intervention, but not in the control group, a significant decrease in the SUD value was found.Conclusion and significanceThe results show that the CIPOS technique is as effective as pure mental exposition in reducing physiological stress. In addition, a superiority in reducing subjective distress was found compared to pure mental exposition. Possible explanations of these effects are discussed. (shrink)

In this article we try to give a philosophically reflected introductory overview of the current theoretical developments in the field of evolutionary aesthetics. Our aim is not completeness. Rather, we try to depict some of the central assumptions and explanatory tools frequently used in evolutionary accounts of human aesthetical preferences and address a number of currently debated, open research questions.

Ethics is a field in which the gap between words and actions looms large. Game theory and the empirical methods it inspires look at behavior instead of the lip service people sometimes pay to norms. We believe that this special issue comprises several illustrations of the fruitful application of this approach to ethics.

Many studies show that punishment, although able to stabilize cooperation at high levels, destroys gains which makes it less efficient than alternatives with no punishment. Standard public goods games (PGGs) in fact show exactly these patterns. However, both evolutionary theory and real world institutions give reason to expect institutions with punishment to be more efficient, particularly in the long run. Long-term cooperative partnerships with punishment threats for non-cooperation should outperform defection prone non-punishing ones. This article demonstrates that fieldwork data from (...) hunter-gatherers, common pool resource management cases and even PGGs support this hypothesis. Although earnings in PGGs with a punishment option may be lower at the beginning, efficiency increases dramatically over time. Most ten-period PGGs cannot capture this change because their time horizon is too short. (shrink)

Bankers have a reputation for deviating from standard morals. It is an open question, though, if this claim can be substantiated. Here, it is tested directly if bankers respond differently to moral dilemmas. Evaluations of the moral acceptableness of behavioural options in two trolley cases by bankers (n = 23) are compared to those of ordinary people (n = 274). An apparent difference in response behaviour between the groups can be fully explained by a difference in the response behaviour of (...) men and women. When controlling for gender, no differences between bankers and other people remain. (shrink)

We report three studies which test a sexual selection hypothesis for male war heroism. Based on evolutionary theories of mate choice we hypothesize that men signal their fitness through displaying heroism in combat. First, we report the results of an archival study on US-American soldiers who fought in World War II. We compare proxies for reproductive success between a control sample of 449 regular veterans and 123 surviving Medal of Honor recipients of WWII. Results suggest that the heroes sired more (...) offspring than the regular veterans. Supporting a causal link between war heroism and mating success, we then report the results of two experimental studies. We find evidence that female participants specifically regard men more sexually attractive if they are war heroes. This effect is absent for male participants judging female war heroes, suggesting that bravery in war is a gender specific signal. Finally, we discuss possible implications of our results. (shrink)

The recent sociobiology debate has raised fundamental and previously unresolved conceptual problems. Evolutionary Instability - Logical and Material Aspects of a Unified Theory of Biosocial Evolution - offers ap- proaches for their solution. The scientific applications comprise the dynamics and evolutionary instability of hierarchically organized systems, especially systems of interacting behavioural phenotypes in animals and man. The technical apparatus is thoroughly explained in intuitive terms within the text, and illustrated by numerous familiar examples and graphical representations, supplemented by an informal (...) summary and discussion. The analyses offer new theoretical perspectives to such diverse fields as philosophy of science, evolutionary biology, general system theory and sociology. (shrink)

We review the literature on various approaches to modeling animal intergroup conflict behavior in theoretical biology, highlight the intricacies emerging in the process of adding due biological realism to such models, and point out recent empirical findings that can inspire future theorizing.

The ten original studies included in this Research Topic investigate selected assumptions and predictions of parochial altruism theory in detail. We, the editors, are convinced that their highly instructive findings will help researchers interested in parochial altruism, but also in intergroup psychology more generally, to gain a much more fine-grained understanding of the interplay of altruistic and spiteful motives in human decision making in the context of intergroup relations. The broad range of disciplines represented by the authors contributing to this (...) Research Topic and the variety of methods used in their studies are representative for the current interdisciplinary interest in parochial altruism. The most important insight that, in our view, can be derived from the works collected here is that human decision making in intergroup contexts is more complex than suggested by current theory. Thus, we hope that future theorizing on parochial altruism will be stimulated by the evidence gathered in this Research Topic. In this editorial, we briefly highlight central findings reported here, which, to us, appear most informative for prospective enhancements of parochial altruism theory. (shrink)
