Tao Te Ching · Chapter 47

不出戶，知天下；不闚牖，見天道。
其出彌遠，其知彌少。
是以聖人不行而知，不見而名，
不為而成。

Without going outside his door, one understands (all that takes
place) under the sky; without looking out from his window, one sees
the Tao of Heaven. The farther that one goes out (from himself), the
less he knows.

Therefore the sages got their knowledge without travelling; gave
their (right) names to things without seeing them; and accomplished
their ends without any purpose of doing so.
