 People coming from a scientific perspective, who are interested in descriptive evolutionary ethics, speak of morality as something to be explained scientifically—as in familiar talk of “how morality evolved”. Here ‘morality’ refers, as noted earlier, to a certain set of empirical phenomena, such as the observed capacity of human beings to make normative judgments, or the tendency to have certain sentiments such as sympathy or guilt or blame, or certain ‘intuitions’ about fairness or violence. Just as we can inquire into the origins and functions of other traits, such as human linguistic capacities, we can inquire into the origins and functions of the various psychological capacities and tendencies associated with ‘morality’.
