The past was worth remembering and knowing in its own right. It was not behind us, never truly behind us, but under us, holding us up, a foundation for all that was to come and everything that had ever been.
I had ancestors who were slave-holders, which is a difficult piece of family history to say the least. In a recent New York Times article on the subject of modern attitudes toward our slave-holding past, the writer noted that we all want to be from "innocent origins." I _know_ I'm not. Then again, I suspect most of us are not.
