The Master said, “A true gentleman is one who has set his heart upon the Way. A fellow who is ashamed merely of shabby clothing or modest meals is not even worth conversing with.” (Analects 4.9)
There are three things to beware of through life: when a man is young, let him beware of his appetites; when he is middle-aged, of his passions; and when old, of covetousness, especially.
The young should be dutiful at home, modest abroad, careful and true, overflowing in kindness for all, but in brotherhood with love. And if they have strength to spare they should spend it on the arts.
Therefore only through education does one come to be dissatisfied with his own knowledge, and only through teaching others does one come to realize the uncomfortable inadequacy of his knowledge. Being dissatisfied with his own knowledge, one then realizes that the trouble lies with himself, and realizing the uncomfortable inadequacy of his knowledger.
