From the documentation of sleepers to a man’s description of his life through the experiences of his colleagues, friends and family, Calle’s work emphasizes the absence of the artists to create portraits and capture universal ideas of contemporary life.
"So this has been my whole professional life! Public art can create permeable membranes between the inside and outside of systems, spaces, and even the souls of citizens. Public artists need more breathing space to experiment and do R&D. They need to be brought in at the very inception of projects, so they can do their first work as a certain kind of thinker." -- Mierle Laderman Ukeles, 2001
