来书云：「夫子昨以良知为照心。窃谓良知，心之本体也，照心，人所用[1]功，乃戒慎恐催之心也，犹思也，而遂以戒慎恐催为良知，何欤？」
能戒慎恐惧者，是良知也。
来信说：「先生昨日以良知为照心。我以为良知是心的本体，照心是人所用功夫，是戒慎恐惧之心，如同思一样；却把戒慎恐惧当作良知，为什么呢？」
能戒慎恐惧的，就是良知。
Your letter says: 'Yesterday you made innate knowledge the mirroring mind. I should have thought innate knowledge the mind's substance, the mirroring mind the work man applies — the vigilant, fearful mind, as it were a thinking; why then make vigilance and fear innate knowledge?'
That which can be vigilant and fearful is innate knowledge.
