Against Public Reason\u2019s Alleged Self-Defeat

Abstract

Mainstream political liberals hold that state coercion is legitimate only if it is justified on the grounds of reasons that all may reasonably be expected to accept. Critics argue that this public justification principle (PJP) is self-defeating, because it depends on moral justifications that not all may reasonably be expected to accept. To rebut the self-defeat objection, I elaborate on the following disjunction: one either agrees or disagrees that it is wrong to impose one’s morality on others by the coercive power of the state. Those who disagree reject PJP, they understand politics as war. Those who agree accept PJP, they understand politics as competition. Political competitors abide by PJP to avoid politics as war, by enforcing PJP on political combatants they engage in a war that is unavoidable. In both cases their exercise of political power has a justification that is reasonably acceptable to all.
