It begins by reviewing how moral philosophy treats borders. It argues that anthropology can add understandings of moralization of borders in practice. It first looks at the moral view of borders from national interiors; in such places, borders are often treated as single dimensional moral demands and solutions, either threats to national essence or to unbounded humanity. It looks at moral thought in action, as people to come to borders to enact such visions. It then turns to borderlanders themselves, who are diverse but often experience a life of moral ambiguity and complexity because of the everyday crossing processes of life. Borderlanders offer the possibility of a more nuanced pattern of moral thinking. It concludes by arguing for a normative philosophical generalization of this lesson,in which the dense, multi-stranded, rich interactions of immigrants and hosts in borderlands points to a pro-immigrant stance based on accumulated interactions and emergent bonds.
