Political Obligation and Legal Duty

为了构建法律和国家的基本理论，这项研究通过考察法律义务和政治义务之间的差异，表明公平竞争原则之所以失败，是因为搭便车的人可以公平竞争，合法国家比自然状态对人类更有利，因为他们是凡人，当且只有当每个国家都收取建立一个全球(可能是普遍的)法律国家的责任时，我们才有政治义务。

In order to construct a fundamental theory of law and state, this research shows, by examining the difference between legal duty and political obligation, that the principle of fair play fails because free riders can play fair, that a legal state is more profitable to human beings than a state of nature because they are mortal, and that we owe political obligation if and only if each state charges the duty to establish a global (and potentially universal) legal state.
