Abstract
It would be terrible for us if humanity ceased to exist after we all die. But of course, eventually humanity will go out of existence. Does this result in a vicious regress if our flourishing hangs on what happens after us? Mark Johnston thinks so. In this note, I explain how Johnston's objection can be avoided. Briefly, our activities have a meaning horizon that extends for some generations after us. What matters is that we make a positive difference to the lives of those generations, not that they themselves necessarily flourish.
