《围炉夜话·第十六则》
又见到有些后辈原本十分聪明，却突然做出品性低下的事；有些原本平庸愚鲁，倒成为品德很好的人，这就是在于父兄的栽培教养了。
又见有子弟聪颖者，忽入下流；庸愚者，转为上达，则父兄之培植所关也。
There are also those who were originally very intelligent but suddenly became degenerate; some who were originally mediocre and stupid became very virtuous. This is due to the cultivation and education of their parents.
