What do we owe future humans? In principle, it seems obvious that we should do what we can to make life better for the generations that follow, just as our ancestors did for us.

Join Dave as he speaks to Harvard psychologist and philosopher Joshua Greene about what drives our moral instincts, and to futurist Ari Wallach about how tapping into spirituality and emotion can help us become better ancestors to those yet to be born.

Find out more about Joshua Greene’s work, including how to buy his book Moral Tribes: Emotion, Reason, and the Gap Between Us and Them, on his website. Also, check out Giving Multiplier, a donation system Josh co-created based on research about how to improve charitable giving decisions.

Ari Wallach is the author of Longpath: Becoming the Great Ancestors Our Future Needs. Find out about the book and Longpath in general here. You can also read Ari’s article for Wired about addressing short-termism, or watch his TED talk.
