A humorous miscommunication between a mystic and a logician
Huizi said, "You're not a fish — how do you know what fish enjoy?"
Zhuangzi said, "You're not me, so how do you know I don't know what fish enjoy?"
Huizi said, "I'm not you, so I certainly don't know what you know. On the other hand, you're certainly not a fish — so that still proves you don't know what fish enjoy!"
Zhuangzi said, "Let's go back to your original question, please. You asked me how I know what fish enjoy — so you already knew I knew it when you asked the question. I know it by standing here beside the Hao."
