Recent developments of the concept of "sense of community" have highlighted the multiplicity of people's senses of community. In this article, the authors introduce the theory of the dialogical self as a means of theorizing the conflicts that can arise between a person's commitments to multiple communities. They ask the question, "When faced with conflicting community commitments, how does a person decide where his or her allegiances lie?" The contribution of the theory of the dialogical self is illustrated through an idiographic analysis of diaries kept by one British woman living through World War II. Conflicting commitments to her home community and to the national community's war effort provoke troubling dilemmas and efforts to resolve them through internal dialogues. Contributions to theory, research, and practice are discussed. (Contains 1 figure and 2 footnotes.)
