Though much has been written about when paternalistic intervention is justified, and about how it is justified, much less has been written about who may do the intervening. This is a substantial lacuna in our understanding of the nature of justified paternalism. By examining the question of who it is that may most appropriately interfere with the course of our decision-making, we can learn something useful both about paternalism and about the nature of friendship.In this essay I will argue that (...) friendship and paternalistic intervention are linked. Friendship of the close, intimate variety that I will be discussing is in part constituted by the fact that one friend is morally justified in interfering with the other’s decisions. Intimate friendship involves a partial meshing of identities. This meshing of identities manifests itself in part by the liberties that one friend takes in guiding the life of the other. Paternalistic intervention between friends can thus be justified because it expresses the union of the friends, and because it preserves that union. (shrink)
