Content: History shows considerable variation in marital practices: polygyny has been widely practiced, some societies have approved of extra-marital sex and, arguably, recognized same-sex marriages, and religious or civil officiation has not always been the norm (Boswell 1994; Mohr 2005, 62; Coontz 2006). More fundamentally, while the contemporary Western ideal of marriage involves a relationship of love, friendship, or companionship, marriage historically functioned primarily as an economic and political unit used to create kinship bonds, control inheritance, and share resources and labor. Indeed, some ancients and medievals discouraged ‘excessive’ love in marriage. The ‘love revolution’ in marriage dates popularly to the 18 th century (Coontz 2006, Part 3). Ethical and political questions regarding marriage are sometimes answered by appeal to the definition of marriage. But the historical and cultural variation in marital practices has prompted some philosophers to argue that marriage is a ‘family resemblance’ concept, with no essential purpose or structure  (Wasserstrom 1974). If marriage has no essential features, then one cannot appeal to definition to justify particular legal or moral obligations.
