The common good

The republican tradition in political theory has long insisted on the centrality of the notion of the common good, arguing that if the state is forced to track the common good then it won't dominate its citizens. Not only can it serve the republican ideal of promoting freedom as non-domination of members of the public against private masters: the state will not itself have the cast of a public master; it will interfere with people in the course of tracking the common good but the interference will not be of the dominating variety (Sellers 1995; Pettit 1997; Skinner 1998; Viroli 2002). I have two aims in this chapter. One is to look at what ‘the common good’ has got to mean if this republican axiom is going to be plausible, and the other is to consider how the common good might be identified and empowered in political life, as republican theory suggests that it ought to be. In pursuing these aims – though they relate to my projects rather than his – I will draw freely on Brian Barry's early but still unsurpassed discussion of common or public interests (Barry 1965). The chapter is in three sections. The first section argues that ‘the common good’ cannot plausibly refer to people's common net interests but only to the common interests that people have as members of the public.
