Thomas Hobbes' Theory of Sovereign and Law--Based on Leviathan [PDF]

open access: yes, 2016
托马斯·霍布斯是近代哲学和政治理论的奠基者之一,他的主权者和法律思想作为他国家理论的主体,占有重要地位。但是霍布斯的论述相对分散,即使在《利维坦》这本具有代表性的著作中,有关主权者与法律的论述也是散见于各个章节之中。因此本文旨在将有关主权者与法律思想分散性的论述按照一个独立思维逻辑进行归纳、整理,展示出霍布斯主权者在法律这个角度的独特面貌。 本文包括三部分内容,分别是导言、正文和结语,其中正文有四章:第一章介绍了霍布斯主权者思想的历史背景与基础理论,作为霍布斯论述主权者理论的铺垫 ...
