It is like writing history with lightning and my only regret is that it is all so terribly true.

One thing that struck me in my study of history is how people are excluded. I don't mean just racial minorities or women. Pretty much all poor people who don't have documents are excluded from history and its records. People who were illiterate usually didn't leave any primary documents.

My mother was born in your state, Mr. Walter, and my mother was a Quaker, and my ancestors in the time of Washington baked bread for George Washington's troops when they crossed the Delaware, and my own father was a slave.

Sixty years after the end of the war, the time has come to make this information available. With the number of survivors and witnesses diminishing by the day, and the reality that the Holocaust is fading into the pages of history and memory, we should not have to wait any longer.

Just by my home is an entrance to the sewers they used in the Warsaw uprising. I grew up knowing people died down there. Warsaw was once a battleground; then it became a morgue. It's a city littered with ghosts. And that never left me.

We took the traditional lands and smashed the traditional way of life. We brought the diseases and the alcohol. We committed the murders. We took the children from their mothers. We practised discrimination and exclusion. It was our ignorance and our prejudice. And our failure to imagine that these things could be done to us.
