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.

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.
