《宋史·列传·卷五十二》
曾说 ：我要是生活在唐朝元和时期，在李绛、崔群手下做事，这一生也就无愧了。 他作文著书，多涉及规劝讽谏，因为这一点他不为流俗所容，所以屡次被排斥。
尝云： 吾若生元和时，从事于李绛、崔群间，斯无愧矣。 其为文著书，多涉规讽，以是颇为流俗所不容，故屡见摈斥。
He once said: "If I had lived during the Tang Dynasty, under the guidance of Li Jiang and Cui Qun, I would have been content with my life." Many of his writings were devoted to admonition and satire, and for this reason, he was often marginalized by the mainstream.
