Blind hope faces a blank wall waiting for a door in it to open. Doors might be nearby, but blind hope keeps you from locating them; in this geography, despair can be fruitful, can turn you away from the wall, saying NO to deprivation. And this despair in one institution or one site can lead to the location of alternatives, to the quest for doors, or to their creation. The great liberation movements hacked doorways into walls, or the walls came tumbling down. In this way, despair and hope are linked.
