《庄子·内篇·齐物论》
瞿鹊子向长梧子问道： 我从孔夫子那里听到这样的谈论：圣人不从事琐细的事务，不追逐私利，不回避灾害，不喜好贪求，不因循成规；没说什么又好像说了些什么，说了些什么又好像什么也没有说，因而遨游于世俗之外。
瞿鹊子问乎长梧子曰： 吾闻诸夫子：圣人不从事于务，不就利，不违害，不喜求，不缘道，无谓有谓，有谓无谓，而游乎尘垢之外。
Once Qu Quezi asked Changwunzi: I have heard such a talk from Confucius: The saint does not get involved in trivial affairs, does not pursue self-interest, does not avoid disasters, does not like to be greedy, and does not follow conventions. He doesn’t say much but seems to have said something, says something but seems to have said nothing, and therefore he wanders outside the world.
