In Conceptions of Parenthood Michael Austin provides a rigorous and accessible philosophical analysis of the numerous and distinct conceptions of parenthood. Austin rejects the 'proprietarian', 'best interests of the child', and 'biological' conceptions of parenthood as failing to generate parental rights and obligations but considers more sympathetically the 'custodial relationship', 'consent', and 'causal' conceptions of parenthood and ultimately defends a 'stewardship' conception.
