充分抑或必要：正义的边界问题

摘要

Walzer advocates the correct normative principle that anything depends on the nature of the thing itself and distributive justice presupposes a world with borders. Boundaries function in different ways, so that multiple justices should be discussed according to different boundaries in different contexts. This appropriately ends realism. There are three representative views of setting the boundaries of justice ： cooperative practice, political coercion and common identity, which did not give the necessary and sufficient condition of the applied principle of distributive justice. Social justice is a complex concept and the ideal nation-state type is the most effective way of integration, which can realize the effective integration of these three viewpoints, and is the strongest form of justice boundary ; but in the eontext of globalization, the role of this nation-state integration is being challenged, and a new form of justice boundary is forming, so that a new global theory of justice needs to be developed.%沃尔泽主张任何事物的正确的规范原则都取决于那种事物的性质,分配正义预设了一个有边界的世界,不同的边界会以不同的方式产生作用,应该根据相关于不同情境的不同边界来讨论多重正义。这是对罗尔斯主义的一种适当终结。设定正义边界的三种代表性观点：合作实践、政治强制与普遍认同,都没有给出分配正义原则适用的充分必要条件。社会正义是一个复合型的概念,理想类型的民族国家是其最有效的整合者,可以实现这三种观点的有效整合,也是正义最强的边界形式;但在全球化背景下,民族国家的这种整合作用正在受到挑战,新的正义边界形式正在形成,我们需要发展新的全球正义理论。
