Taking stock of standard philosophical analyses of the concept, it is proposed that the domain of morality be defined by reference to seven characteristics: normativity, informality, importance, universality, categoricalness, overridingness, and a reference to beneficence and justice as the basic contents of its rules. These features establish a rather sharp distinction between moral and conventional rules. Recent literature in evolutionary morality and moral psychology, however, challenged the existence of a neat distinction between the moral and the conventional domains. The paper (...) discusses three prominent objections to the proposed analysis that can be found in the empirical literature on morality: one centering on the relevance of moral sentiments, one based on the phenomenon of “harmless wrongdoing”, and one on the rejection of the universality and independence from authority of the moral domain. It is shown that the proposed analysis can be defended in light of the empirical findings. (shrink)
