"Matta's discovery of the 'open cube' is of the greatest importance. Opening up the reality one wants to represent like a cube allows one to understand that what we perceive of the physical world is 'enclosed' and contradicts what we think. We are the crossroads of space. The paintings [Matta] produced with this procedure...compare and oppose perspective, reveal the violent and creative contrast between 'what one sees' and 'what one thinks.'"
