What makes humans moral beings? This question can be understood either as a proximate question or as an ultimate question. The question is about the mental and social mechanisms that produce moral judgments and interactions, and has been investigated by psychologists and social scientists. The question is about the fitness consequences that explain why humans have morality, and has been discussed by evolutionary biologists in the context of the evolution of cooperation. Our goal here is to contribute to a fruitful (...) articulation of such proximate and ultimate explanations of human morality. We develop an approach to morality as an adaptation to an environment in which individuals were in competition to be chosen and recruited in mutually advantageous cooperative interactions. In this environment, the best strategy is to treat others with impartiality and to share the costs and benefits of cooperation equally. Those who offer less than others will be left out of cooperation; conversely, those who offer more will be exploited by their partners. In line with this mutualistic approach, the study of a range of economic games involving property rights, collective actions, mutual help and punishment shows that participants' distributions aim at sharing the costs and benefits of interactions in an impartial way. In particular, the distribution of resources is influenced by effort and talent, and the perception of each participant's rights on the resources to be distributed. (shrink)

Our discussion of the commentaries begins, at the evolutionary level, with issues raised by our account of the evolution of morality in terms of partner-choice mutualism. We then turn to the cognitive level and the characterization and workings of fairness. In a final section, we discuss the degree to which our fairness-based approach to morality extends to norms that are commonly considered moral even though they are distinct from fairness.

This study uses a sample of 242 European professional purchasers to examine the six characteristics of the decision-making process developed by Jones. The illustration mobilizes six original scenarios reproducing typical purchasing situations. Two versions of each scenario were used, one representing low moral intensity and the other showing high moral intensity. Two populations were sampled: one of 120 purchasers responding to the first version of the questionnaire and a second of 122 different purchasers responding to version two. Each version contained (...) three low-moral-intensity scenarios and three high-moral-intensity scenarios. The research also investigates two concepts suggested by Hannah et al. :663–685, 2011): examining the complexity of ethical decision-making through scenarios and microsocial professional ethical contexts. The findings reveal that neither traditional individual characteristics nor standard company characteristics have a real impact on two stages of Rest’s model. They also show that internal locus of control and a high microsocial ethical environment have a positive impact on purchaser awareness and intention to act ethically for four of the six dimensions: magnitude of consequences, social consensus, temporal immediacy, and concentration of effect. Moral intensity factors also have a positive impact on these four dimensions. The two other dimensions are not related to the independent variables. (shrink)

The aim of this study is to examine the decision-making processes at work among French buyers—whether beginners or more experienced individuals, when confronted with a dilemma involving an ethical or non-ethical choice to be made. We go on to illustrate these dilemmas through the use of five original scenarios that reproduce typical situations that arise in a purchasing context in relation to the environment, physical integrity, conflict of interest, or paternalism. Based on 172 participants, the results of our study show (...) that, ethical decision-making depends very clearly on two main factors: expertise and gender. The study also reveals that there is not always a coherent link between ethical choices made and the reasons and justifications given for those choices. Ethical options chosen are not exclusively justified on the grounds of purely ethical reasons but also on the grounds of commercial or economic reasons, or else reasons of avoidance. (shrink)

Il apparaîtra, en des termes explicites, que nous cherchons, prioritairement, à nous distinguer de cette lecture à livre ouvert, immédiate, qui caractérise une certaine école du commentaire de l'œuvre, qui suppose que la vérité du ...
