The anonymous policy wonk who runs the Carneades.org YouTube channel joins Mark and Bill to discuss the core concept of his new book, Are All Lives Equal?: Why Cost-Benefit Analysis Values Rich Lives More and How Philosophy Can Fix It. Should economics really be measuring the value of life at all? Can it do this in any principled way? Can economists really understand how much joy cat videos really bring us? What should parasitic micro-organisms value? Were all the world's religions originally infections diseases? No question is off the table! Mark philosophizes at partiallyexaminedlife.com. Bill improvises (and teaches) at chicagoimprovstudio.com. Hear more at philosophyimprov.com. Support the podcast to get all our post-game discussions and other bonus stuff.
