《礼记·祭义》
用嘉肴美味，岁时祭祀，这不能算作是孝，只能算作是养 君子的所谓孝，是全国的人都称羡喝彩地说： 有这样儿子的爹娘真是有福气呀！ 这才是所谓的孝啊。
亨孰膻芗，尝而荐之，非孝也，养也。君子之所谓孝也者，国人称愿然曰：如此，所谓孝也已。
Using fine foods to offer sacrifices to your ancestors at set times cannot be said to be filial piety; it must be said that it is no more than raising animals. A gentleman’s so-called filial piety consists in having the entire nation say with admiration, “How fortunate the parents are to have such a son!” This is what filial piety is truly about.
