《宋史·列传·卷一百九十六》
更化之初，群臣都能奋发努力，可是不久，傅伯成以谏官身份发议论而罢官；蔡幼学以词臣身份发议论而罢官；邹应龙、许奕以发议论而罢官，这几个人所发议论皆不出格，但也不能为朝廷所容忍，所以人们开始明哲保身、缄口不言。
更化之初，群贤皆得自奋。未几，傅伯成以谏官论事去，蔡幼学以词臣论事去，邹应龙、许奕又继以封驳论事去。是数人者，非能大有所矫拂，已皆不容于朝。故人务自全，一辞不措。
At the beginning of the reforms, all the ministers were full of enthusiasm, but soon, Fu Bocheng was removed from office for expressing his opinions as a谏官(諫官); Cai Youxue was removed from office for expressing his opinions as a Ci Chen (詞臣); and Zou Yinglong and Xu Yi were removed from office for expressing their opinions. These individuals’ opinions were not out of line, but they could not be tolerated by the court. So people began to protect themselves and keep their lips sealed.
