But are there ways of conferring advantage on their children that parents don’t have a right to engage in? For example, is there a difference, morally speaking, between sending your children to an elite private school and reading them bedtime stories or helping them with their homework? This is among the questions that Brighouse and Swift consider in a book that is analytically rich and—to liberal egalitarians, at least—philosophically and politically provocative. 

I spoke to Swift, who teaches political theory at the University of Warwick (Brighouse is a professor of philosophy at the University of Wisconsin-Madison in the  United States), and began by asking him what he and his co-author mean by “the family” for analytical purposes.
