郭沫若对毛泽东《在延安文艺座谈会上的讲话》(以下简称《讲话》)有一句评语:“凡事有经有权。”毛泽东很欣赏这句评语,觉得找到一个知音。郭老的意思是,《讲话》的内容,有些是常理和普遍规律,即“经”;有些则只是适应一定环境和条件的办法,即“权”。毛泽东赞赏郭老这句评语,表明毛并没有认为自己的《讲话》句句是永远的真理, Guo Moruo had a remark on Mao Zedong’s “Speech at the Yan’an Literature and Art Symposium” (hereinafter referred to as “speech”): “Everything has its own merits.” Mao appreciated the remark and found a companion. The meaning of Guo Lao is that the contents of “speech” are some common and universal laws, that is, “經”, while others are only ways to adapt to certain circumstances and conditions, that is, “power”. Mao Zedong appreciated Guo’s remark, indicating that Mao did not consider his “speech” sentence to be an eternal truth.
