This treatise insists as following. (1) The Linguistic turn does not mean that it changes the philosophical problems to the linguistic problems. It has the metaphysical and epistemological implications. (2) About the concept of certainty, Prof. Chung asserts the ordinary certainty operating in the language games. (3) His attempt is lacking the metaphysical ardent desire. (4) The metaphysical certainty is started in the justification about language structure itself which permits the ordinary certainty. (5) The metaphysical certainty appears from the concept of ‘the given’ which performs the transcendental function. (6) The metaphysical problems are not the problems that are satisfied with selecting the specific linguistic framework conventionally. The language restricts our thinking and action. (7) The pluralism which Prof. Chung asserts ignores the normativity grounded in the ordinary language. (8) This point is confirmed by the fact the concept of ‘fitting’ is not justified.
