This world is made of one after another ordinary person.

这个世界是由一个又一个普通人组成的。

We live in such a world. So we have to constantly communicate with different kinds of people.

我们活在这样一个世界上，就要不断地和各种人打交道。

And where there are people there are all sorts of different rules that come with them.

而有人的地方，就会不可避免地出现各种各样的规则。

Some of these rules are written.

有些规则会被写下来。

The others, however, are hidden in the dark waiting for smart people to find them out.

This is not the dark side of this society. It's just the natural result of human interaction.

这并不是社会的黑暗，而是人际互动的必然。

We can't live in a world ruled completely by solid rules. A world like that is hell. And it will make our civilizaiton stagnant.

我们不可能生活在一个完全有铁律统治的社会中，那是地狱;而且那样会让人类文明陷入停滞。

If we are to make our civilization develop, we have to activate that flexibility that makes us human.

人类文明要想发展，必须充分激发我们作为人的灵活天性。

And this nature, this soft nature, will inevitably bring a lot of rules that stay unseen.

而这种天性，是柔性的，所以它必然会带来很多看不见的规则。

So, right, from this perspective, the world is cruel .

所以，没错，从这个角度讲，世界的确是残酷的。

But this is the world that you live in.

但这就是你生活的世界。

Embrace it.

接受它吧。

Only by doing this can you live on.

只有这样，你才能走下去。
