The second justification is the Civic Friendship Argument, according to which we should uphold the doctrine of public rules because of the role it plays in realising civic friendship (Williams 1998: 244). According to this view, civic friendship can exist within a society only when citizens are able justifiably to regard themselves and others (and justifiably be regarded by themselves and others) as doing what is necessary to sustain reasonably fair terms of social cooperation. Publicity facilitates each of these ends. Just as members of an orchestra are denied a common good when they cannot hear, or otherwise appreciate, their own or others’ contributions to their joint performance, so too citizens are denied the good of civic friendship when they are denied awareness of their own or others’ compliance with the principles of justice.
