在柏拉图的城邦问题研究中,正义思想是其问题研究的根本出发点。柏拉图提出城邦秩序的混乱和个人生活规范的失常会招致城邦的衰落,而这归咎于人们没有掌握正义思想的真正理念。当人们能够驾驭正义思想的真正内涵时,人们就能通过利用这种思想使自己的行为得到约束和规范,从而令城邦得到复兴。本文遵循柏拉图的这种政治理念,尝试分析和探究柏拉图的城邦正义思想。 In the study of Plato’s urban aggression, the just idea is the fundamental starting point of its research. Plato suggested that the disorder of the city-state order and the disorder of the personal life-style would lead to the decline of the city-state, which was attributed to the real idea that people did not grasp the idea of ​​justice. When people can harness the true meaning of just thought, one can revive the city by using it to constrain and regulate one’s own behavior. This article follows Plato’s political philosophy and tries to analyze and explore Plato’s polity of city-state justice.
