《宋史·列传·卷一百八十七》
 惟有先生衷心信服龟山先生的讲席已有一年多了，况且曾经从学于伊川先生之门，得到没有传承的孔孟之道于一千五百年之后，性情明而修，行为完而洁，扩其道以广大，体验其道以仁恕，精深微妙，各终其极致，汉朝、唐代的各位儒生没有与之相近似的。
其惟先生服膺龟山先生之讲席有年矣，况尝及伊川先生之门，得不传之道于千五百年之后，性明而修，行完而洁，扩之以广大，体之以仁恕，精深微妙，各极其至，汉、唐诸儒无近似者。
Only the gentleman has wholeheartedly believed in Guishan's teachings for more than a year, not to mention that he once studied under Yichuan, obtaining the untransmitted teachings of Confucius and Mencius after fifteen hundred years. He is intelligent and refined, his conduct is impeccable and pure, he extends his teachings to be extensive, and he experiences his teachings with benevolence and forgiveness. He is profound and subtle, and he has reached the极致 of his abilities. No Confucian scholars in the Han and Tang dynasties have come close to him.
