“Mankind has advanced. Human progress is ceaseless. We can look at Bosnia or Zaire or Rwanda and conclude that building just societies is a fool's errand. We are always, despite our advances, only one sin away from slipping into the abyss of terror and ignorance.
But that is not so. Generations upon generations have driven the human race farther and farther from darkness. Past episodes of abominable human cruelty are kept vivid in the memories of succeeding generations. "Never again," is the admonition passed from the survivors of the Holocaust to their descendants and to us all. And although such an important reminder will not always prevent the occurrence of cruelty and violence even at levels approaching genocide, the civilized world is more inclined to organize opposition to such tragedies if not as early as we should, at least sooner than we once would have.”
