The Problem of Justification and the Proviso
摘要
This chapter elevates Rawls’s proviso from procedural footnote to a structuring framework of pluralistic justification, allowing comprehensive doctrines to inform public reason if translated into reciprocal terms. It contrasts Rawls’s political domain with Habermas’s comprehensive discourse ethics, arguing the proviso better excludes ethical intrusion while preserving motivational resources from citizens’ traditions. This reinterpretation positions the proviso as the book’s core mechanism for sustaining legitimacy amid ethical pluralism, extensible to non-liberal contexts like Confucianism and AI.
