The Lives of the Philosophers: Simone Weil

The History of Bad Ideas: Short-Form Video
Today’s bad idea is one with a very recent history but also a long backstory: David talks to author and journalist James Marriott about what happens when the written word gets supplanted by video and when videos get shorter and shorter. Did the rot set in with television, with YouTube or with TikTok? Is short-form video a symptom or a cause of our shrinking attention spans? What does it mean to have a TikTok prime minister? And is there any way to get people reading again? The New Dark Ages by James Marriott is out next month https://bit.ly/3TJR7zd You can find out everything you need to…

The History of Bad Ideas: Decadence
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…

The History of Transhumanism: Origins
Today it’s the first episode in a new series about the weird and wonderful world of transhumanism: the idea that human beings can be transformed by technology and machines.

Why did the early transhumanists tend to be socialists? What made H. G. Wells such an influence on supposedly respectable scientists? And how does all this foreshadow the world of Silicon Valley today? A reminder that we have a…

An Ageing World: Simone de Beauvoir on Old Age
For the final episode in our series on living in an ageing world David talks to Lyndsey Stonebridge about one of the most interesting and challenging of all writers on the subject of old age – Simone de Beauvoir. Why did Beauvoir believe that we are all duplicitous about the elderly? How did she experience her own ageing body and the prospect of her own death? What did she learn from watching Sartre age and die? And what makes her a prophet for the world we live in today?
