 The first has to do with the moral underpinnings of the communal view. It is helpful to think of communal accounts of the common good as appealing to a certain conception social life (e.g., Rousseau 1762b; Hegel 1821; Walzer 1983). According to this conception, citizens form their various private and sectional interests within the framework of a more fundamental effort to maintain certain social conditions together. The political bond is prior to their private interests in a certain way, so the political relationship may sometimes require citizens to set their private interests aside in order to act collectively to maintain the relevant social conditions. Perhaps the clearest example of this is national defense (see section 9  below). When defending the constitutional order against a foreign threat, political morality requires citizens to act collectively in defense of common interests, without organizing their efforts in a way that answers specifically to their competing private interests in different levels of protection.
