"I first questioned the mark as meaning and then even as focus; I then questioned the frame as containment, the edge as the beginning and end of what I see… consider the possibility that nothing ever really transcends its immediate environment… I tried to respond directly to the quality of each situation I was in, not to change it wholesale into a new or ideal environment, but to attend directly to the nature of how it already was. How is it that a space could ever come to be considered empty when it is filled with real and tactile events?"

- Robert Irwin, 1977.
