Yi-Fu Tuan holds culture and environment and topophilia and environment as distinct in order to show how they mutually contribute to the formation of values. Topophilia examines the search for environment in the city, suburb, countryside, and wilderness from a dialectical perspective, distinguishes different types of environmental experience, and describes their character.
