For the lesson of such stories [of resistance to Nazi atrocities] is simple and within everybody's grasp. Politically speaking, it is that under conditions of terror, most people will comply but some people will not, just as the lesson of the countries to which the Final Solution was proposed is that "it could happen" in most places but it did not happen everywhere. Humanly speaking, no more is required, and no more can reasonably be asked, for this planet to remain a place fit for human habitation.
