“What happened, and what might have happened?”

“Life and study have persuaded me of the openness of history. There is no inevitability in history. Thinking about what might have happened, what could have happened, is a necessary element in trying to understand what did happen. And if, as I believe, individual acts of decency and courage make a difference, then they need to be recorded and remembered.”

“True fear has nothing to do with what might happen to you, however painful or vile that might be. True fear is all about what might happen to someone you love.”

“Einmal ist keinmal, says Tomas to himself. What happens but once, says the German adage, might as well not have happened at all. If we have only one life to live, we might as well not have lived at all.”

“I have a dream of what would have happened if what happened instead hadn't.”

“I have never met a vampire personally, but I don't know what might happen tomorrow.”
