当我们思考“日常生活中的公共性”这个问题的时候，“共同体”就成为绕不过去的一个核心：人和人之间如何群处在一个共同空间中，进而形成一个“共同体”，在其中每一个“成员”愿意（或被要求）按照一定规范有序地群处在一起？奠定共同体之规范性基础、协调所有日常人际互动的那套规范，又由谁订立？背后的根据是什么？…… 政治哲学，就是研究人之群处问题（及其背后的本体论根据）之学问；而精神分析的研究视域，则涉及最基源性共同体形态——家庭。
When exploring “the publicness in everyday life”, we have to first focus on the key issues of “community”: How do people live in a shared space that evolves into a “community”, in which every “member” is willing (or required) to live together in accordance with a set of rules? And who, on what basis, developed this set of rules, laying the foundations of the normativity of the community and governing people’s interactions in everyday life? Political Philosophy studies the group living of human beings (and the underlying ontological basis), while Psychoanalysis focuses on families, the basic form of community.
