That isn’t a task for philosophers, though it’s not clear who could do a better job today. Bill Gates and others gave us some warning of the pandemic, but the world was caught unawares. The political thinker Ivan Krastev says we’re living with a radicalization of the imagination that embraces left and right. For years, climate change activists sought to curb air travel; what once seemed utopian happened overnight. Right-wing nationalists have long demanded closed borders; suddenly even the EU’s most visible achievement, open borders between Member States, was cast aside. What else can we begin to imagine? We know the economy is collapsing, but that determines nothing. In Germany, the Great Depression sealed the triumph of fascism. In the United States it spawned the closest thing to social democracy the country ever knew.
