The great postwar trials brought to light a terrifying number of documents testifying to the sacrifice of the individual in the "medical interests of the community." In the minutes of these trials one finds testimony and reports showing how, with the consent and, at times, even under the formal order of public authority, certain research centers systematically demanded to be furnished with persons from concentration camps for their medical experiments. One finds how they were delivered to such centers, so many men, so many women, so many for one experiment, so many for another. There are reports on the conduct and the results of such experiments, of the subjective and objective symptoms observed during the different phases of the experiments. One cannot read these reports without feeling a profound compassion for the victims, many of whom went to their deaths, and without being frightened by such an aberration of the human mind and heart. But We can also add that those responsible for these atrocious deeds did no more than to reply in the affirmative to the question We have asked and to accept the practical consequences of their affirmation.
