Norm Externalisation and the Evolution of Cooperation

In a recent article, Kyle Stanford gives an account of what he terms "externalisation", understood as our tendency to objectify or externalise moral demands and obligations. According to Stanford, externalisation is a distinctive feature of our moral psychology which is adaptive since it enables and preserves cooperation. I claim that the main issue with this account is that it assumes an overly psychological and individualist, inward-To-outward looking perspective. I advocate taking an alternative perspective that turns the spotlight to social practices and the social reality they create. I show how, seen in this light, norm externalisation becomes a side-effect instead of an adaptation deserving of a special explanation.
