我知道你知道我知道你知道的事:
你知道我知道你知道我知道的事.

I know the thing you know that I know you know
You know the thing I know that you know I know

我知道你不知道我不知道你知道的事;
我不知道你知道我知道你不知道的事.

I know you don't know what I don't know about what you know;
And I don't know what you know about what you don't know.

我知道你知道我知道你知道的事;
我不知道你不知道我不知道你不知道的事.

I know what you know what I know about what you know;
And I don't know what I don't know about what you don't know.

我們到底知道了什麼?

What have we known?
