A plough man said to Tzu-lu, a follower of Confucius, ‘Under Heaven there is none that is not swept along by the same flood. Such is the world and who can change it? As for you, instead of following one who flees from this man and that, you would do better to follow one who shuns this whole generation of men.’ And with he went on covering the seed.
Tzu-lu went and told his master, who said ruefully, ‘One cannot herd with birds and beasts. If I am not to be a man among other men, then what am I to be?’
