卢梭的社会契约论继承了以往社会契约论的合理成分,并提出了自己的主权在民学说。公意是卢梭政治哲学中一个很重要的概念,他提出公意概念的目的就是为了公民通过履行遵守公意的责任而实现自由。公意是人民主权的体现,是以公共利益为依归的,而法律又是建立在公意的基础之上,是公意在具体政治实践中的表现。 Rousseau’s social contract theory inherited the rational composition of the social contract theory in the past, and put forward his own sovereignty theory in the people. Consensus is a very important concept in Rousseau’s political philosophy, and his purpose of expressing the concept of gratitude is to enable citizens to be free by fulfilling their duty of observance. Public opinion is the manifestation of people’s sovereignty and public interests, and the law is based on public opinion, which is the expression of public opinion in concrete political practice.
