 Public reason accounts tend to focus on the problem of justifying political coercion. The solution they propose is that political coercion is justified if it is supported on the basis of reasons that all reasonable persons can share. Interest in public reason accounts started with Rawls’ Political Liberalism, but Rawls developed the idea more fully in later works. Rawls’ starting-point is the following problem of legitimacy (Rawls 2001: 41): “in the light of what reasons and values … can citizens legitimately exercise … coercive power over one another?” The solution to this problem that Rawls proposes is the following “liberal principle of legitimacy”: “political power is legitimate only when it is exercised in accordance with a constitution (written or unwritten) the essentials of which all citizens, as reasonable and rational, can endorse in the light of their common human reason” (Rawls 2001: 41).
