My dear and unfortunate successor:
I shall conclude my account as rapidly as possible, since you must draw from it vital information if we are both to — ah, to survive, at least, and to survive in a state of goodness and mercy. There is survival and survival, the historian learns to his grief. The very worst impulses of humankind can survive generations, centuries, even millennia. And the best of our individual efforts can die with us at the end of a single lifetime.
