Negotiating Logic, Languages, and Worldviews: Introducing the Fourth Person Philosophy
In discourses on comparative and global philosophies, scholars frequently negotiate various kinds of logic such as Aristotelian logic, formal logic, empathic logic, mystics' logic, the so-called "logic of sokuhi," etc. While logic is often treated to be translinguistic, there are clear connections between various forms of logic and specific languages. This paper will introduce what I call "Fourth-Person Philosophy" as a method to negotiate and understand various forms of logic and languages. This philosophy is inspired by languages such as Ainu and Ojibwe, Huayan and Chan/Zen philosophies, Nishida's philosophy of basho, and Dōgen's philosophy of expression. It will present an innovative method to negotiate and understand various ways of thinking and to conduct global philosophy.
