 And the article closes with the line “Perhaps [biologists] can eventually do what philosophers have never managed, and explain moral behavior in an intellectually satisfying way.” These passages epitomize a growing theme in the popular and scientific media, echoing claims made forty years ago with the emergence of sociobiology, when E.O. Wilson suggested that “the time has come for ethics to be removed temporarily from the hands of the philosophers and biologicized” (Wilson 1975, 562). For their part, moral philosophers will hasten to point out that they are not primarily in the business of “explaining moral behavior” in the sense of causally explaining the origins of our capacity for moral judgment or of various associated emotional and behavioral dispositions. If a moral philosopher asks “whence morality,” she is more likely to be concerned with the justification of moral principles or the source and nature of obligation. Still, there are important potential connections between the scientific explanatory issues and philosophical ones, opening the way for profitable interdisciplinary inquiry.
