Evolutionary theory and the foundation of moral principles

Evolutionary biology is supposed to be relevant to ethics by a number of authors. Some of them believe that it may provide and justify basic moral values. Others argue that evolutionary biology is relevant only in a negative way. They assume that it reveals the illusory nature of any attempt to justify basic moral values. In this paper one example of either approach is criticized. An analysis of examples can hardly offer sufficient grounds for a general conclusion. Nevertheless I believe that evolutionary theory is of little help when we deal with the most basic ethical questions. Three themes which are often though to provide a link between evolutionary biology and (meta)ethics — altruism, sociality and human nature — do not in fact establish that link.
