The History of Bad Ideas: Decadence

5 August 2026

00:00 / 01:04

Today’s bad idea is also one that is very hard to pin down: David talks to writer and literary scholar Ian Ellison about the concept of decadence, which went from explaining the fall of ancient Rome to becoming a label modern artists wanted to claim for themselves. What makes a society decadent? Is it always a bad thing? When does decadence explain what’s happening and when does it distract from what’s happening? Was Weimar Germany the best of decadence or the worst of it? And how decadent are we today?

Out now on PPF+: a bonus episode to accompany this series in which David talks to political historian David Klemperer about the idea of social credit, which promised to save the world in the 1920s and 1930s and ended up doing nothing of the sort. A fascinating story of cranks, conspiracy theorists and crypto-fascists with curious echoes in Silicon Valley today.
