But however minimal, however threadbare, it (collective memory) is ballast of a kind. We all need that seven-eighths of the iceberg, the ballast of the past, a general past, the place from which we came. That is why history should be taught in school. to all children, as much of it as possible. If you have no sense of the past, no access to historical narrative, you are afloat, untethered; you cannot see yourself as a part of the narrative, you cannot place yourself within a context. You will not have an understanding of time, and a respect for memory and its subtle victory over the remorselessness of time.
