Why? Why use the room as introduction to an apologia? Because the room, though windowless and cold at night, is a hothouse. Because the room is the past, though it has no history of its own. Because, as the physical being-there of a bed or horizontal plane determines what we call love; as a high place must exist before God's word can come to a flock and any sort of religion begin; so must there be a room, sealed against the present, before we can make any attempt to deal with the past.
