Only the willfully blind can ignore that the history of human existence is simultaneously the history of pain: of brutality, murder, mass extinction, every form of venality and cyclical horror. No land is free of it; no people are without their bloodstain; no tribe entirely innocent. But there is still this redeeming matter of incremental progress. It might look small to those with apocalyptic perspectives, but to she who not so long ago could not vote, or drink from the same water fountain as her fellow citizens, or marry the person she chose, or live in a certain neighborhood, such incremental change feels enormous.

People who believe in fundamental and irreversible changes in human nature are themselves ahistorical and naive. If novelists know anything it’s that individual citizens are internally plural: they have within them the full range of behavioral possibilities. They are like complex musical scores from which certain melodies can be teased out and others ignored or suppressed, depending, at least in part, on who is doing the conducting. At this moment, all over the world — and most recently in America — the conductors standing in front of this human orchestra have only the meanest and most banal melodies in mind.
