This paper attempts to clarify the lives of people that socially were becoming individualized by reviewing theories of G. H. Mead and E. H. Erikson of the relationship between individual and society. They were organizing their own lives rather than adapting them to their life course provided by society. The theories of Mead and Erikson, though they had been proposed in the early 20th century, were still eff ective to consider their own lives to be organized. Because of this, it was valuable to review and consider these theories. As a result, I found that the relationship between self and community could be located in the relationship between individual and society by reviewing Mead’s interactional social psychology, Erikson’s identity theory, and Mead’s social theory of practice. In this mediation, individuals’ selves were constructed in the communities and those communities consisting of society were also reconstructed by people’s involvement.
