《容斋随笔·卷二·忠恕违道》
并不是说它不能包括理的本源。违是说离去，不是说背叛。老子说： 最好的东西象水，能使万物得到而不争功，处在众人不愿住的地方，所以它接近自然之理。 
非谓其未足以尽道也。违者违去之谓，非违畔之谓。老子曰：上善若水，水善利万物而不争，处众人之所恶，故几于道。
It does not say it does not include the source of reason. Violation means leaving, not betrayal. Laozi says: The best thing is like water, which can benefit all things without claiming credit, and lives in places where people are unwilling to live, so it is close to the truth of nature.
