Ch 08 On Rules For Conduct In Life - Admonition 10

Wrath beyond measure produces estrangement and untimely kindness destroys authority. Be neither so harsh as to disgust the people with thee nor so mild as to embolden them.

Severity and mildness together are best
Like a bleeder who is a surgeon and also applies a salve.
A wise man uses neither severity to excess
Nor mildness; for it lessens his authority.
He neither exalts himself too much
Nor exposes himself at once to contempt.
A youth said to his father: ‘O wise man,
Give me for instruction one advice like an aged person.’
He said: ‘Be kind but not to such a degree
That a sharp-toothed wolf may become audacious.’
