材料一：有子（孔子弟子）曰：“孝弟（悌）也者，其为仁之本与！”

——《论语·学而》

材料二：约之二：吾族务要恪遵祖训，以伦理为纪纲，父慈子孝，兄友弟恭，夫妇和顺；一家雍睦（和睦），端由于此。即同宗相处，须要安分守己，尊莫凌卑，强莫欺弱；卑幼者不许冒犯长上，富贵者宜怜穷困。循规蹈矩，宗族称孝，乡党称弟（悌）。

——何兹全《中国文化六讲·训约十四条》

材料三：宣圣谕。圣谕曰：“孝顺父母，尊敬长上，和睦乡里，教训子孙，各安生理，毋作非为。”此六事乃太祖高皇帝（朱元璋）曲尽做人的道理，件件当遵守。能遵守的便是好人。有一件不曾遵守便是恶人。愿我一族长幼会集祠（堂）中，敬听宣读，悉心向善，皆作好人，有过即改，共为盛世良民，贻子孙无穷福泽。

——明《虎墩崔氏族谱·族约》
