Rancière says that contemporary art is not a concept. It is a space.
The space that once occupied the painting. That is combinations of objects which occupy the spaces where old portraits on the walls were visible.
The art is to build spaces and relationships to reconfigure materially and symbolically the territory of the ordinary. Behind is the failure of art that wanted to build a new life. Shadow dissolved in the cleansing rain, no less, the staging of sleep leaks.
