鱼我所欲也

    鱼，我所欲也；熊掌，亦我所欲也。二者不可得兼，舍鱼而取熊掌者也。生，亦我所欲也；义，亦我所欲也。二者不可得兼，舍生而取义者也。生亦我所欲，所欲有甚于生者，故不为苟得也；死亦我所恶，所恶有甚于死者，故患有所不辟也。如使人之所欲莫甚于生，则凡可以得生者何不用也？使人之所恶莫甚于死者，则凡可以辟患者何不为也？由是则生而有不用也，由是则可以辟患而有不为也。是故所欲有甚于生者，所恶有甚于死者。非独贤者有是心也，人皆有之，贤者能勿丧耳。

    一箪食，一豆羹，得之则生，弗得则死。呼尔而与之，行道之人弗受；蹴尔而与之，乞人不屑也。万钟则不辩礼义而受之，万钟于我何加焉！为宫室之美，妻妾之奉，所识穷乏者得我与？乡为身死而不受，今为宫室之美为之；乡为身死而不受，今为妻妾之奉为之；乡为身死而不受，今为所识穷乏者得我而为之；是亦不可以已乎？此之谓失其本心。

材料：周公其人，堪称中国历史上伟大的政治家和改革家，他主持完成了周初的改革，其关于“天下治式、社会模式、行为范式”方面的创举，着实当得起“万世之谋”四个字。在平定“三监”之乱以后，周公亲自谋划落实分封，主要分四个层级进行：第一层是周天子，第二层是分封的“姬姓”王族子弟，第三层是分封的功臣子弟，第四层主要分封的是殷商旧族后裔。钱穆先生对此的评价是“周人封建，亦由当时形势之实际需要逐步逼迫而成，同时亦是周民族对于政治组织富于一种伟大气魄之表现。”西周以前，中国的社会组织结构多具有原始氏族的特征，总体上是很松散的。周公对宗法制的完善，结下了一张由“个人——家庭——家族——国家”织成的比较严密的社会网络。周公还认为“乐至则无怨，礼至则不争”，要让整个社会形成君臣、父子、兄弟、夫妇、朋友之间的上下尊卑关系。总之，作为中国历史上第一次规模宏大的变革，周公改制无疑是成功的。
