《文心雕龙·征圣》
圣人能够全面考察自然万物，并深入到其中精深奥妙的地方去；这样才能写成堪称楷模的文章，其表达的思想也才能与客观事物相吻合。
夫鉴周日月，妙极机神；文成规矩，思合符契。
Sages can comprehensively examine the nature of all things, and go deep into the profound and mysterious places in them; in this way, they can write articles that can be used as models, and the expressed ideas can also be in line with objective things.
