《淮南子·齐俗训》
所以，追求 是 的人，不真是在追求真理，而只不过是在找符合自己意思的东西；寻找 非 的人，不真是在剔除错误，而只不过是在排除违逆自己心意的东西。
故求是者，非求道理也，求合于已也；去非者，非批邪施也，去忤于心者也。
Therefore, those who pursue what is right are not truly pursuing truth, but are merely seeking what suits their own will; those who seek what is wrong are not truly eliminating errors, but are merely excluding what goes against their own will.
