This article tries to show that the notion of parenthood emerges in the context of an historical evolution where the social bond tends to reproduce itself, beyond traditional kinship systems. This should be brought seriously into the discussion, insofar as the psychoanalytical concept of drive conflict and the centrality of interpreting the transference are in danger of being forgotten. The first part describes the current modes of « culture and its discontents ». Afterwards, we will study some avatars of borderline subjectivation who rationalize themselves within a discourse on parenthood. In conclusion, parenthood and kinship are put into a dialectical relationship by being put into anthropological perspective.
