Social sculpture is a phrase used to describe an expanded concept of art that was invented by the artist and co-founder of the German Green Party, 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.
