Evolutionary ethics posits the evolution of dispositions to love self, kin, and friend. Christianity claims that God's ethical demand is to love one's neighbor. I argue that the distance between these two positions can be interpreted theologically as original sin, the disposition to disobey God's command and practice self-love and nepotism rather than neighbor-love. Original sin requires Incarnation and Atonement to unite God and humanity. The ancient doctrine of the Atonement as educative does not invoke the Fall. Its revival may (...) help reconcile Christianity and evolutionary ethics. (shrink)
