“Truth" when examining events and records of the past was always precarious, uncertain. No man could say for certain how the river of time would have flowed, cresting or receding, bringing floods or gently watering fields, had a single event, or even many, unfolded differently.

It is in the nature of existence under heaven, the dissenting scholars wrote, that we cannot know these things with clarity. We cannot live twice, or watch as moments of the past unfurl, like a courtesan's silk fan. The river flows, the dancers finish their dance. If the music starts again it is starting anew, not repeating itself.”
