The universality of philosophical hermeneutics is rooted in language. Hermeneutics circularity includes both circularity between preview and texts and circularity between locality and unity. Understanding is a kind of language game of interpretation-talk and an activity of questioning-answering. There are neither predetermined meaning or any difference between "inner language" and "outer language" in this kind of game. The meaning of texts is gradually generated and predominated in the infinite circularity of horizon. Philosophical hermeneutics will provide philosophical foundation and methodological framework for dialogue of religions all over the world.
