This week Bruce takes a deep dive into the epistemological ideas in Jonathan Rauch’s book The Constitution of Knowledge. Rauch is a fan of Karl Popper and a former guest on this show. He makes the case that the creation of objective knowledge relies on institutions and norms as much individuals. All claims must be open to criticism and not based on authority. This applies not just to science but to journalism, law, and all areas where humans seek to fallibly move closer to truth. Bruce considers how these claims relate to critical rationalism, specifically Deutsch’s conception of static vs dynamic societies. Does this provide another clue as to why we got stuck in static societies for so many millennia?
