One is astonished in the study of history at the recurrence of the idea that evil must be forgotten, distorted, skimmed over. We must not remember that Daniel Webster got drunk but only that he was a splendid constitutional lawyer. We must forget that George Washington was a slave owner . . . and simply remember the things we regard as creditable and inspiring. The difficulty, of course, with this philosophy is that history loses its value as an incentive and example; it paints perfect man and noble nations, but it does not tell the truth.
