Another significant passage is found in the Confucian Analects, and is as follows, quoting, as before, Dr. Legge's translation, "Ch'ên K'ang asked Po Yü, the son of Confucius, saying, 'Have you heard any lessons from your father, different from what we have all heard?' Po Yü replied, 'No; he was once standing alone when I hurriedly passed below the hall, and he said to me, "Have you learned the Odes?" on my replying, "not yet," he added, "If you do not learn the Odes, you will not be fit to converse with." I retired and studied the Odes. Another day he was in the same way standing alone, when I hastily passed below the hall, and he said to me, "Have you learned the Rules of Propriety?" on my replying, "not yet," he added, "If you do not learn the Rules of Propriety, your character cannot be established." I then retired and studied the Rules of Propriety. I have heard only these two things from him.' Ch'ên K'ang retired, delighted, saying, 'I asked about one thing, and I have got three things. I have heard about the Odes, I have heard about the Rules of Propriety, and I have heard that the superior man maintains a distant reserve toward his son.'" Confucius was a master who felt himself to be in possession of great truths of which his age was in deep need, and he offered his instructions to rich and poor alike, upon the sole condition of receptivity. "I do not open up the truth," he said, "to one who is not eager to get knowledge, nor help out any one who is not anxious to explain himself. When I have presented one corner of a subject to any one, and he cannot from it learn the other three, I do not repeat the lesson." For aught that appears, the son of Confucius was wholly dependent for whatever he knew or received, upon his father. According to Confucius, an acquaintance with the Odes, and with the Rules of Propriety, form a very considerable part of the equipment of a scholar. They embrace such subjects as could be comprehended and assimilated, one would suppose, only by the assistance of a competent teacher. That in the education of his own son, Confucius should have contented himself with a casual question, and a single hint, as to the pursuit of those branches which were in his eyes of preëminent importance, is a circumstance so singular that if it were not handed down upon the same authority as the other facts in the life of the sage, we might be disposed to doubt its credibility.
