In volume 14 of the distinguished Praxiology series, editors JA(c)rA me Ballet and Damien Bazin examine the concept of positive ethics in economics. Positive ethics is first and foremost a model for the construction of theoretical economic reasoning reflecting on ethical practices within economics and introducing a model of reasoning that takes individual ethical behavior and its aftereffects into account. Divided into three parts, in aAltruism,a the contributors discuss the notion of unselfish concern for the welfare of other, and its place in economic practice, in aCommitment,a the authors discuss reason as being central to economic theory as well as the position of ethical behavior, and in aResponsibility,a the idea that man is not an island unto himself but a being involved in a set of relationships, is examined. If a person is simultaneously responsible for himself and others, then how far does his responsibility extend?
