《论衡·卷十六·讲瑞篇》
假如凤凰的翅膀又长又宽，麒麟的身体又高又大，那么见到它们的人认为它们不过是大鸟巨兽罢了，怎么能识别它们是凤凰、麒麟呢？
使凤皇羽翮长广，骐驎体高大，则见之者以为大鸟巨兽耳。何以别之？
If the wings and body of a phoenix were longer and larger, the people who saw them would think it was merely a large bird or a giant beast. How could they recognize it as a phoenix or a unicorn?
