This paper, while discussing the unique characteristics and development of human language which are different from other living organisms, shows how those factors influence on the identity-shaping of human beings. First of all, this paper understands language as the dialogical self expression of one s beingness. While other living organisms live their own lives based on the bodied language, human beings cannot forbid its bodied language from getting colonized by the symbolic language system. This colonization, however, leads one to cast one s existential questions and recover one s beingness embedded in the body, the linguistic quality of which is called existential language. While fusing one s consciousness and subconsciousness into a dialogical entity through existential language, one leads oneself into the stage where one is finally able to communicate with oneself, others, and other organisms as they are by not instrumentalizing others, the linguistic quality of which is called spiritual language. The results of this study show the ontological, epistemological, and methodological ideas on how we can restructure the symbolic language system which is unique to human beings in order to sustain or recover our bodied language and the true meanings of language in the pursuit of our lives.
