Shu-sun Wu-shu was disparaging Confucius. Tzŭ Kung said: It is no good. Confucius is proof against detraction. The wisdom of other men is like hills and mountain-peaks, which however high can still be scaled. But Confucius is like the sun or the moon, which can never be reached by the foot of man. A man may want to cut himself off from their light, but what harm will that do to the sun or the moon? It only shows very plainly that he has no notion of the measurement of capacity.
