Hell is out of fashion - institutional hells at any rate. The populated infernos of the 20th century are more private affairs, the gaps between the bars are the sutures of one's own skull. A valid hell is one from which there is a possibility of redemption, even if this is never achieved, the dungeons of an architecture of grace whose spires point to some kind of heaven. The institutional hells of the present century are reached with one-way tickets, marked Nagasaki and Buchenwald, worlds of terminal horror even more final than the grave.
