How do you know the fish are happy

Two philosophers on a bridge. One of them wins the argument by cheating, beautifully.

Chapter 06 of 12 in The masters were funny

Zhuangzi and his friend Huizi are walking on a bridge over the Hao river. Zhuangzi looks down and says, see how the fish come out and dart around. That is what fish enjoy.

Huizi says, you are not a fish, how do you know what fish enjoy.

Zhuangzi says, you are not me, how do you know I do not know what fish enjoy.

Huizi, who is good at this, says fine, I am not you and I do not know you. You are not a fish, and so your not knowing about fish is complete.

And Zhuangzi says, let us go back to the beginning. You asked me how I know what fish enjoy. You already knew that I knew it when you asked me. I know it by standing here, on the Hao.

He cheats. He gets out of the trap by pointing at where the question was actually asked from, which is two men standing on a bridge, already sharing a world, already knowing things about each other that the argument says are impossible. The logic was airtight and it was about a situation that was not happening.

I love this one because it is the only piece of ancient philosophy I know that wins by being annoying. And it sets up a thing I keep bumping into. The hard problem of other minds, stated carefully, proves too much. If nothing crosses from inside one head to another, then Huizi cannot ask his question either, because asking assumes a listener he cannot verify.

Where it points, and Zhuangzi does not say this, is that the sharing was never a transfer between two sealed boxes. There is one field of knowing here and two people standing in it, which is a strange thing to say about a bridge in the fourth century BC, and easy to overread.

What is not overread is his last line. I know it by standing here. Not by inference. By being where the fish are.
