"It seems to me that even the bluntest word, the bluntest letter is still more good-natured, still more honest, than silence. . . . All who remain silent are dyspeptic. Clearly I would not have bluntness underestimated: it is by far the most humane form of contradiction and, amid modern pampering, one of our foremost virtues."
