"Culture" in singular is an abstraction. The study of body culture is always a study of body cultures in plural - of their variety and differences, their assimilation and distinction, their conflicts and contradictions. This demands a comparative approach to otherness.
Otherness is not only something to be "accepted" as "deviating" from a given standard, but a fundamental condition of knowledge. Without the attention to other identities, one is disable to discern one's own identity. By the comparative method, observation oscillates between identity and alterity.
The comparative study of body cultures, thus, contributes to intercultural understanding.
