《墨子·13章 尚同(下)》
墨子说道： 智者做事，必须考虑国家百姓所以治理的原因而行事，也必须考虑国家百姓所以混乱的根源而事先回避。 
子墨子言曰： 知者之事，必计国家百姓所以治者而为之，必计国家百姓之所以乱者而辟之。 
Mozi said: The wise men must consider the reasons why the state and the people are well governed and act accordingly, and they must also consider the reasons why the state and the people are in chaos and avoid them in advance.
