 All of this leaves us with some important questions. Many contemporary social issues turn on disagreements about when citizens may take up a privatized perspective and when they must reason from the standpoint of the common good. Social justice is often silent on these issues because people could, in principle, act as justice requires, whether they are moved by a scheme of private incentives or by a concern for common interests. These social issues are best understood as turning on disagreements about the nature of the political relationship and the form of mutual concern that it requires. Philosophical reflection has an important role to play in shedding light on this relationship and what it requires of us beyond what we owe to each other as a matter of justice.
