 A conception of the common good will define a privileged class of abstract interests. Citizens are understood to have a relational obligation to create and maintain certain facilities because these facilities serve the relevant interests. The interests in the privileged class are “common” in the sense that every citizen is understood to have these interests to a similar  degree.[11]  The interests are “abstract” in the sense that they may be served by a variety of material, cultural or institutional facilities. A wide variety of interests figure prominently in the literature, including: the interest in taking part in the most choiceworthy way of life (Aristotle Pol. 1323a14–1325b31); the interest in bodily security and property (e.g., Locke 1698; Rousseau 1762b); the interest in living a responsible and industrious private life (Smith 1776); the interest in a fully adequate scheme of equal basic liberties (Rawls 1971 and 1993); the interest in a fair opportunity to reach the more attractive positions in society (Rawls 1971); and the interest in security and welfare, where these interests are understood as socially recognized needs that are subject to ongoing political determination (Walzer 1983).
