 Members of a political community stand in a social relationship, and this relationship also requires them to think and act in ways that embody a certain form of mutual concern. The common good defines this form of concern. The common good incorporates certain basic requirements of social justice, as citizens must provide one another with basic rights and freedoms and they must not exploit each other. But the common good goes beyond the basic requirements of justice because it requires citizens to maintain certain patterns of conduct on the grounds that these patterns serve certain common interests.
