The moral achievement of statesmen must be judged in terms which take account of the limitations of human society which the statesman must, and the prophet need not, consider.

The final sin of man, said Luther truly, is his unwillingness to concede that he is a sinner. The significant contribution of modern culture to this perennial human inclination lies in the number of plausible reasons which it was able to adduce in support of man's good opinion of himself.

The inevitable hypocrisy, which is associated with the all the collective activities of the human race, springs chiefly from this source: that individuals have a moral code which makes the actions of collective man an outrage to their conscience. They therefore invent romantic and moral interpretations of the real facts, preferring to obscure rather than reveal the true character of their collective behavior. Sometimes they are as anxious to offer moral justifications for the brutalities from which they suffer as for those which they commit. The fact that the hypocrisy of man's group behavior... expresses itself not only in terms of self-justification but in terms of moral justification of human behavior in general, symbolizes one of the tragedies of the human spirit: its inability to conform its collective life to its individual ideals. As individuals, men believe they ought to love and serve each other and establish justice between each other. As racial, economic and national groups they take for themselves, whatever their power can command.
