Tao Te Ching 81 48

Truthful words are not necessarily beautiful.
Beautiful words are not necessarily true.
Sages do not argue.
Those who argue are not sages.
Those who have true knowledge are different from those with book knowledge.
Those who have book knowledge are not wise.

– Chapter 81

In the pursuit of knowledge everyday something more is added.
In the pursuit of Tao every day something is let go of.

-Chapter 48
