What is this? This is a wonderful piece of abstraction. It is saying, you don't need to know squat about what's inside the body of this function.

Of course, I can then close it off, and off we go.

但是这能告诉你一些信息,这是什么？,这是一段完美的抽象,它的意思是你不需要知道,这个函数的内部构造，你不必担心参数是否重名，因为它们已经被预存了,你不需要担心我如何使用它,它告诉了你你该如何操作，从而正确的使用它，当然我也可以把它关掉。

Because,indeed,they don't exist They're merely possible And we might say,you've got to exist in order for something to be bad for you But once we say that it seems we're running towards the position that in that case,death can't be bad for me because of course,when I'm dead,I don't exist ? So how can anything be bad for me?

因为他们其实并不存在,他们只是一种可能,我们由此认为你必须首先存在,某事才会让你害怕,但我们一旦这么说,我们似乎会得出这个结论,这种情况下死亡不可能让我害怕,因为我死了就不存在了,所以我怎么会害怕？
