A weekly series reimagining a better society post COVID-19. Over the last six months we have looked broadly at the social contract, narrowly at the changes we’d like to make within ourselves, and consistently at the changes we’d like to see in society. Is a world constitution a good idea? What would it look like? How might it be enforced? We look at Enlightenment and 20th Century arguments for a world constitution as we reflect on the scale of the challenges facing us today.
