Kravee: Is value unbounded? So if I have two really good lives, happy lives, is that twice as good? Or once you've already got one, maybe a second one's still really good. Are they diminishing returns to value itself? And the intuitive case for this is very strong, I think. Kravee: But there are really bad problems for that view too - it matters how many people have lived in the past and so on. The fact that we ought to model to be like figuring out what were the lives of the ancient Egyptians like, he says.
It’s always a little humbling to think about what affects your words and actions might have on other people, not only right now but potentially well into the future. Now take that humble feeling and promote it to all of humanity, and arbitrarily far in time. How do our actions as a society affect all the potential generations to come? William MacAskill is best known as a founder of the Effective Altruism movement, and is now the author of What We Owe the Future. In this new book he makes the case for longtermism: the idea that we should put substantial effort into positively influencing the long-term future. We talk about the pros and cons of that view, including the underlying philosophical presuppositions.
