 In the vast literature on the common good, several topics stand out as important subjects of concern. One important topic is democracy. Democracy figures prominently in philosophical reflection about the common good because there is broad agreement among philosophers—though by no means universal agreement!—that a private society would be defective in terms of the way that members make collective decisions. Collective decision-making in a political community must unfold in its public life, that is, in the sphere of interaction in which citizens transcend their own private concerns and reason from the standpoint of the common good.
