Tao Te Ching · Chapter 58

其政悶悶，其民淳淳；
其政察察，其民缺缺。
禍兮福之所倚，福兮禍之所伏。孰知其極？其無正。
正復為奇，
善復為妖。
人之迷，其日固久。
是以聖人方而不割，
廉而不劌，
直而不肆，
光而不燿。

The government that seems the most unwise,

Oft goodness to the people best supplies;

That which is meddling, touching everything,

Will work but ill, and disappointment bring.

Misery!--happiness is to be found by its side! Happiness!--misery
lurks beneath it! Who knows what either will come to in the end?

Shall we then dispense with correction? The (method of) correction
shall by a turn become distortion, and the good in it shall by a turn
become evil. The delusion of the people (on this point) has indeed
subsisted for a long time.

Therefore the sage is (like) a square which cuts no one (with its
angles); (like) a corner which injures no one (with its sharpness).
He is straightforward, but allows himself no license; he is bright,
but does not dazzle.
