What are human beings in the context of sport? The aim of this paper is to inquire the possibility of the understanding on human beings through sport, proposing the perspectives and the advantages of the current philosophical literature on sport. First, we have classified the modes of the understanding on human beings in four, i. e. human beings (1) as the being objective, (2) as the being selfhood, (3) as the being other, and (4) as a whole. (1) lies outside the scope of this paper since the nature science is dealing with it. The matters of the other three are (2) the understanding on the authentic self, (3) ethical issue of the serious relationship to others, and (4) the limit of the essentialistic view of human beings. Second, we have examined them in detail based on Eassom's discussion on the philosophy of sport. Rorty, who was mentioned in it, has the negative opinion on human nature, that is antifoundationalism. He provides a model of communities in which people themselves intend to the solidarity with the awareness and sensitivity to radical contingency. This model gives those three modes of the understanding on human beings, the suggestions are as follows; (1) The individuals build themselves by making their own experiences of sport into their own narratives which consist of the terms used in a community. (2) The conversation induced by the narratives has a possibility of the mutual understanding on each community. (3) The way from the awareness of the contingency of sport to the solidarity would provoke the intention to wholeness of human beings.
