It is widely accepted that parents have a fundamental moral obligation to consider and treat their children as each other’s equals. Yet the question of what grounds the equality of status among children in the eyes of their parents has so far been largely neglected in the literature on the philosophy of childhood and the ethics of parenthood. This paper fills this gap by developing a novel theory of the basis of filial equality: it argues that parents ought to consider and treat their children as equals by virtue of loving them. Parental love is the basis of filial equality.
