Analects 16.7-8 · KE SHE
Confucius said, 'There are three things which the superior man guards against. In youth, when the physical powers are not yet settled, he guards against lust. When he is strong and the physical powers are full of vigor, he guards against quarrelsomeness. When he is old, and the animal powers are decayed, he guards against covetousness.' Confucius said, 'There are three things of which the superior man stands in awe. He stands in awe of the ordinances of Heaven. He stands in awe of great men. He stands in awe of the words of sages. 'The mean man does not know the ordinances of Heaven, and consequently does not stand in awe of them. He is disrespectful to great men. He makes sport of the words of sages.'
