What is it to be alien? This article considers the debate concerning alienation/de-alienation launched by Hegel and revisited a half-century ago by Jacques Derrida. It examines the systemic reduction of legal rights of presence that migrants in contemporary Europe regularly encounter. Such experiences lead people to undergo a ‘loss of presence’ in the sense that they question their relationship with the world and the people around them. As Ernesto de Martino proposed, these occurrences constitute a ‘subjective alienation’ brought about by ‘objective alienation’. In this way, they impact one’s personal ontogeny, producing what I call a ‘habitus of migrancy’. As a contribution toward ethnographic theory, the article engages the role of long-term self-reflection in anthropological analysis.
