“History is not just facts and events. History is also a pain in the heart and we repeat history until we are able to make another's pain in the heart our own.”

Context: We celebrate this history, this heritage, as an immigrant nation. And we are strong enough to acknowledge, as painful as it may be, that we haven’t always lived up to our own ideals. We haven’t always lived up to these documents. [... ] We succumbed to fear. We betrayed not only our fellow Americans, but our deepest values. We betrayed these documents. It’s happened before. And the biggest irony of course was -- is that those who betrayed these values were themselves the children of immigrants. How quickly we forget. One generation passes, two generation passes, and suddenly we don’t remember where we came from. And we suggest that somehow there is “us” and there is “them,” not remembering we used to be “them.”

Context: To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty, but also of compassion, sacrifice, courage, kindness. What we choose to emphasize in this complex history will determine our lives. If we see only the worst, it destroys our capacity to do something. If we remember those times and places — and there are so many — where people have behaved magnificently, this gives us the energy to act, and at least the possibility of sending this spinning top of a world in a different direction. And if we do act, in however small a way, we don’t have to wait for some grand utopian future. The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvelous victory.

Context: We are all such accidents. We do not make up history and culture. We simply appear, not by our own choice. We make what we can of our condition with the means available. We must accept the mixture as we find it — the impurity of it, the tragedy of it, the hope of it.
