威廉斯論政治規範性：兩層方法論與系譜學視角

Bernard Williams on Political Normativity: A Two-Level Methodology and Genealogical Perspective

「獨特的政治規範性」是政治現實主義的重要議題。威廉斯（Bernard Williams）的「基本正當化要求」常被視為其代表；既有研究多以工具規範性或認知規範性的元倫理途徑詮釋，未能充分呈現其獨特性。本文主張從「兩層結構」的方法論層面理解：第一層以更基本的需求為支點，提出較寬鬆的正當性觀，僅要求統治者提出正當化敘事，以區分政治秩序與純粹暴力；第二層將之置入具體歷史與社會脈絡，說明其對「我們」的意義，並依批判理論原則引入「真實歷史的系譜學」，檢驗正當化敘事的歷史生成與權力作用，以維持內在批判力。由此，政治規範性奠基於群體行動者對現實與歷史的反思與倫理信心，從而為規範政治理論提供一條不訴諸外在道德基準、內嵌於實踐且可批判的進路。

Distinctively political normativity is a central concern of contemporary political realism. Bernard Williams’s Basic Legitimation Demand (BLD) is often taken as its paradigmatic expression. Yet existing interpretations tend to subsume BLD under meta-ethical accounts of instrumental or epistemic normativity, thereby missing what is distinctive about Williams’s approach. This article proposes a methodological reading in terms of a two-level structure. At the first level, it takes basic needs as the pivot and offers a minimalist conception of legitimacy: rulers must supply a justificatory narrative that distinguishes a political order from sheer domination or violence. At the second level, that narrative is placed within concrete historical and social contexts to clarify what it means—and why it binds—for“us”. To preserve immanent critique, the paper draws on the Critical Theory Principle and develops a genealogy of real history that traces the narrative’s formation and the workings of power. Political normativity, on this view, rests on collective agents’reflective engagement with reality and history, sustained by an ethical confidence in truthfulness, and it offers a practice-embedded yet critical route for normative political theory without appeal to external moral standards.
