You remember clearly--right?--

你们应该记得很清楚
his wonderful proposition.

他那个精彩的命题
"The water in the well belongs to everybody.

"井中的水属于每一个人
But who doubts that those who fetch it

但是谁能质疑从井中取出的水
--the water--that water belongs to him or her?

是属于他们自己的
Because it is his or her product, labor product.

因为这是个人的劳动产品
And what is the value of that water,

这个水的价值是什么
what you are carrying away from the well,

当你离开水井时
what you did fetch from the well?

你从井中得到的到底是什么
Exactly the amount of labor you had to put in, in order to fetch that."

正是为了取水你所付出的劳动"
Clear, right?

清楚明了是吧
A nice theory of property right

这是一个很赞的产权理论
