The fluidity of sculpture is the understanding of reality through the perception, the suggestion and the emotion of the material revealing its forms and expressivity. Giuseppe Penone, who will receive an honorary degree from Brown, is one of the foremost figures of Arte Povera, a 1960s Italian avant-garde movement whose proponents employed common materials to protest the commercialization of art. Through his personal conception of sculpture, he developed a personal artistic language that positions the human being in an equal relationship with nature and environment, which he addresses in his talk.
