Abstract

Much of the bioethical literature on parenthood does not address a fact about parenthood which deserves more attention: parental rights and obligations are attached to socially constructed institutional roles. Both the content of these roles, and the way in which they determine who a child’s parents will be, issue from social and legal institutions of parenthood, and this makes a difference to accounts of the moral basis of parenthood. I will argue that this poses a problem for the causal account of parenthood: the variability of parental obligations, and their assignment, underscores the problems the causal account has with defining the relevant notion of cause and with fixing procreative costs. If institutional role obligations arise only through voluntary undertakings, then understanding moral parenthood as an institutional role makes the voluntarist account of parenthood more attractive. However, I must address two questions: whether such role obligations can arise non-voluntarily, and whether the voluntarist account can deal with common cases of parenthood.
