《史记·七十列传·司马相如列传》
太史公说：《春秋》能推究到事物的极隐微处，《易经》原本隐微却能阐释得浅显，《大雅》说的是王公大人却德及黎民百姓，《小雅》讥刺卑微作者的得失，其流言却能影响朝廷政治。
太史公曰：春秋推见至隐，易本隐之以显，大雅言王公大人而德逮黎庶，小雅讥小己之得失，其流及上。
Grand Historian Sima Qian said: Spring and Autumn Annals can trace things to their most subtle details; the Book of Changes was originally profound, but can be interpreted in a simple way; the Great Odes describe the nobles and aristocrats, but their virtues extend to the common people; the Lesser Odes criticize the gains and losses of humble authors, but their gossip still has an impact on court politics.
