" It does not seem to me, Austerlitz added, that we understand the laws governing the return of the past, but I feel more and more as if time did not exist at all, only various spaces interlocking according to the rules of a higher form of stereometry, between which the living and the dead can move back and forth as they like, and the longer I think about it the more it seems to me that we who are still alive are unreal in the eyes of the dead, that only occasionally, in certain lights and atmospheric conditions, do we appear in their field of vision. "
