Social sculpture is a phrase to describe an expanded concept of art that was advocated by the conceptual artist and politician Joseph Beuys. Beuys created the term “social sculpture” to embody his understanding of art’s potential to transform society. As a work of art, a social sculpture includes human activity that strives to structure and shape society or the environment. The central idea of a social sculptor is an artist who creates structures in society using language, thoughts, actions, and objects.
