In their criticism of various approaches to upbringing and related American family law jurisprudence, liberal theorists tend to underweight the interests of parents in directing the development of children’s values. Considered through the lens of T.M. Scanlon’s contractualism, providing a good upbringing is not a matter of identifying children’s “best interests” or acting in accordance with overriding end-state principles. Rather, children should be raised in accordance with principles for the general regulation of behavior that no one could reasonably reject as a basis for informed, unforced general agreement. The process of ascertaining such principles requires an understanding of relevant values; a good upbringing is what children receive when parents properly value their children, enabling them to appropriately recognize what it is that they have reason to do given the roles that they play. By developing the account of upbringing hinted at in Scanlon’s contractualist monograph, What We Owe to Each Other, this project identifies and responds to some common mistakes in contemporary liberal theorizing on childhood, suggests that contractualism yields a more plausible account of upbringing than alternative approaches, and along the way identifies some implications of contractualism for public policy where individuals properly value the children of others in their community.
