The Sword-Based Jewels Are Less Lethal Than the Sword Based Jewels

It's clear that human social morality has gone through significant changes in the past. But why? What caused these changes? In this episode, I chat to Jeroen Hopster from the University of Utrecht about this topic. We focus, in particular, on a recent paper that Jeroen co-authored with a number of colleagues about four historical episodes of moral change and what we can learn from them. That paper, from which I take the title of this podcast, was called 'Pistols, Pills, Pork and Ploughs' and, as you might imagine, looks at how specific technologies (pistols, pills, pork and ploughs) have played a key role in catalysing moral change.
