 Advocates of the public justification approach to democracy (see section 2.2.2) often argue that democratic citizens and officials have individual moral duties of public justification. John Rawls argues for a “duty of civility” that requires citizens and officials to be prepared to give mutually acceptable justifications for important laws when voting and engaged in public advocacy. Given the inevitability of disagreement about comprehensive moral and philosophical truth in free democracies, the duty of civility requires citizens to appeal to a reasonable “political” conception of justice that can be the object of an “overlapping consensus” between different comprehensive doctrines. While different theorists motivate duties of public justification in different ways, many appeal to the need for exercises of coercive political authority to respect citizens’ freedom and equality.
