From 2001:
Sebald: The moral backbone of literature is about that whole question of memory. To my mind it seems clear that those who have no memory have the much greater chance to lead happy lives. But it is something you cannot possibly escape: your psychological make-up is such that you are inclined to look back over your shoulder. Memory, even if you repress it, will come back at you and it will shape your life. Without memories there wouldn’t be any writing: the specific weight an image or phrase needs to get across to the reader can only come from things remembered – not from yesterday but from a long time ago.
