《孟子·离娄上》4A.28：天下归己若草芥，此之谓大孝
孟子把舜的伟大先落在事亲上：不是先说天下归之，而是先说尽事亲之道。能把父子之伦安顿好，天下的归附反倒成了次要结果。
孟子曰：「天下大悦而将归己，视天下悦而归己，犹草芥也，惟舜为然。不得乎亲，不可以为人；不顺乎亲，不可以为子。舜尽事亲之道，而瞽瞍厎豫。瞽瞍厎豫而天下化；瞽瞍厎豫而天下之为父子者定。此之谓大孝。」
英文参考译文
Mencius said, 'Suppose the case of the whole kingdom turning in great delight to an individual to submit to him. To regard the whole kingdom thus turning to him in great delight but as a bundle of grass - only Shun was capable of this. He considered that if one could not get the hearts of his parents he could not be considered a man, and that if he could not get to an entire accord with his parents, he could not be considered a son. By Shun's completely fulfilling everything by which a parent could be served, Gu Sou was brought to find delight in what was good. When Gu Sou was brought to find that delight, the whole kingdom was transformed. When Gu Sou was brought to find that delight, all fathers and sons in the kingdom were established in their respective duties. This is called great filial piety.'

核心问题
为什么孟子说，舜之所以伟大，根本在于“大孝”？
直接回答
因为在孟子看来，一个人若连最根本的亲亲关系都不能成全，就不足以成人；反过来，舜先把事亲做到极处，才使父子之伦得定，进而带动天下之化。
第一性原理
最广大的秩序不是跳过最亲近的关系建立起来的，而是从最根本的人伦成全中向外展开。

引用提示
不要只抓“天下大悦而将归己”。孟子真正压重的是：若不得乎亲，就还谈不上做人，更谈不上治天下。
