English Original
The wise Zhuangzi and the clever Huizi were strolling on the bridge over the Hao River.
Zhuangzi said, "Look how the fish are swimming so freely and leisurely in the water. That is the joy of fish!"
Huizi replied, "You are not a fish. How can you know the fish are joyous?"
Zhuangzi said, "You are not me. How can you know that I do not know the fish are joyous?"
Huizi argued, "I am indeed not you, so I do not know what you know. But you are certainly not a fish, so it is impossible for you to know the fish's joy. That is certain."
Zhuangzi concluded, "Let us go back to your original question. You asked me, 'How can you know the fish are joyous?' This question implies you already knew that I knew it when you asked. I know the fish's joy from my vantage point here above the Hao River."

智慧的庄子和聪明的惠子在濠水的桥上游玩。
庄子说：“看这些鱼在水中游得多么从容自在，这就是鱼的快乐啊！”
惠子说：“你不是鱼，怎么知道鱼是快乐的呢？”
庄子说：“你不是我，怎么知道我不知道鱼的快乐呢？”
惠子说：“我不是你，固然不知道你；但你也不是鱼，所以你不可能知道鱼的快乐，这是可以肯定的。”
庄子说：“让我们回到你最初的问题。你问我：‘你怎么知道鱼是快乐的呢？’你这样问的时候，就已经知道我知道鱼的快乐了。我是在这濠水桥上知道鱼的快乐的。”
