Abstract

The article presents the most important systematic philosophical questions and problems regarding altruism, outlines various answers to these, discusses them, develops precise definitions of ‘altruism’ / ‘altruistic’, 'self-interested', 'egoistic', etc. and develops a normative theory of altruism. The starting point is an assumption about the ethical function of the normative concept of altruism, namely that it captures an ideal: acting for the benefit of others beyond one's moral duty. On this basis, the normative concept of altruism is defined. This is followed by an overview of the ethics that explicitly or implicitly advocate altruism. The subsequent discussion of psychological altruism centres on the question of whether and, if so, which human motives may be intrinsically aimed at the good of others. The most important such motive is acting out of empathy. The final section addresses whether and how altruistic action can be rational.
