This article is designed to explore the concept of the social sphere and its relations to public life. `Social sphere' here refers to a societal self-organization to create a common cultural landscape on which various forms of performance and public drama are staged, and through which a social bond among strangers is created and public life maintained. It is argued that different societies have different kinds of social spheres with distinctive forms of cultural performance, and thus create various types of (...) public life. Through a genealogical exploration, four kinds of social spheres (religious ceremonies, public festivals, recreation and consumption), associated with four types of performance (ritual, spectacular, theatrical and magical) are identified. The social transformation of the nature of public life is thereby explored. It is here that I see the structural source of modern individualism and its relations to cultural performance. (shrink)
