Abstract

The series friends, rivals, enemies is a seemingly ‘natural’ classification for the relations of states, while the parallel series kin, neighbors, strangers functions as an informal classification system for social relations in general. That we may owe foreigners the hospitality due to strangers has become a matter of discussion among normative theorists, thanks to Kant's Perpetual Peace. Thus the conjunction of friendship and hospitality calls for a conceptual assessment. This assessment uses Aristotle's treatment of friendship (and Derrida's treatment of Aristotle's ‘familial schema’) to establish three primary models of social relations (father to sons, husband to wife, brother to brother). Only ‘brothers’ (agents modeled as brothers) can be friends, rivals, or enemies. Only ‘fathers’ can be hosts who offer strangers the hospitality of the household. By the same token, only ‘fathers’ can be guests or take hostages. Such an assessment brings the conceptual concerns of two fields — international relations and political theory — closer together. In so doing, it rejects anarchy's conceptual hegemony in the field of international relations.
