如果你想像卡根不存在，那么你也就是在想象那个唯一的东西，薛立·卡根不存在。
And if you imagine Kagan not existing, then you're imagining that single thing, Shelly Kagan, not existing.
所以如果想象了薛立存在，那么当然你也就想象了那一个东西，薛立·卡根存在。
And so if you've imagined Shelly existing then of course you're imagining that single thing, Shelly Kagan, existing.
所以你甚至无法想象在一个世界里，薛立存在而卡根不存在。
So you can't even imagine a world in which Shelly exists but Kagan doesn't.
想象在一个世界里卡根存在，而薛立不存在，因为这个世界里面没人叫薛立。
Imagine a world in which Kagan exists, but Shelly doesn't exist, because nobody in the world is named Shelly.
你不可能做到，因为在现实世界里，薛立和卡根指的是，同一个东西的两个不同名字。
And that you can't do, because in the real world of course Shelly and Kagan pick out just two different names of this very same thing.
我们可以容易地想象一个世界里，我不姓卡根或者，反过来，我不叫薛立。
We can easily imagine a world in which I don't have the last name Kagan or perhaps to switch it around, Shelly's not my name.
设想在某个世界里面，薛立存在而卡根不存在。
Look. Suppose we try to imagine a world in which Shelly exists but Kagan doesn't.
所以想象在一个世界里薛立存在，而卡根不存在或者卡根存在而薛立不存在，这就像是要想象在一个世界里，我存在而我不存在。
So imagining a world in which Shelly exists but Kagan doesn't or Kagan exists but Shelly doesn't, that's trying to imagine a world in which I exist but I don't.
