《梦溪笔谈·补笔谈卷二》
今天的众多学问，人人各出己意，离奇不正而浅陋，放弃传统，师心自用，又不止于器物的制作而已。
今之众学人人皆出已意，奇衺浅陋，弃古自用，不止器械而已。
Nowadays, everyone has their own opinions. However, most of the theories and knowledge are strange, incorrect and superficial. These academics abandon tradition and only do as they please. This is not only limited to the production of utensils.
