《论衡·卷十六·商虫篇》
假设虫有智慧，也会责备人说： 你们吃自然所生长的东西，我也吃这些东西，说我吃就是灾变，却不说你们自己吃是灾变。 
设虫有知，亦将非人曰： 女食天之所生，吾亦食之，谓我为变，不自谓为灾。 
If insects had wisdom, they would also blame humans and say: "You eat what nature produces, and I also eat these things. When I eat, it is a disaster, but when you eat it yourself, it is not said to be a disaster."
