and we mentioned that playing the game repeatedly

我们当时也提到过如果多次重复这个博弈
might be able to get us out of the dilemma.

也许可以让我们走出困境
It might be able to enable us to sustain cooperation.

多次重复博弈也许可以让合作持续
And what's going to be good about

在这里好的标准
that is not just sustained cooperation,

仅仅维持合作是不够的
but sustained cooperation without the use of outside payments

我们要的是在没有其他条件时维持合作
such as contracts or the mafia or whatever.

比如没有合约或不是黑手党之类的
So why does this matter?

那么这为什么很重要呢
Well one reason it matters

之所以重要的一个原因
is that most interactions in society,

是因为日常生活中的大部分互动
either don't or perhaps even can't rely on contracts.

可能根本就不需要契约
Most relationships are not contractual.

大部分的关系都不是契约形式的
