David talks to philosopher and author Nikhil Krishnan about the life and times of a little known but highly influential twentieth-century philosopher: J. L. Austin, who believed that the deepest truths lay in understanding how ordinary language worked. Why was Austin so opposed to the ideas of A. J. Ayer? How were his experiences in planning D-Day in 1944 an extension of his approach to philosophy? What made people so frightened of him? And how did such a conventional man have such an unconventional influence on thinkers from California to Cambridge?

In our series about how twentieth-century philosophy and biography intersect, David talks to philosopher Alex Carter about the life of Albert Camus, novelist, playwright, journalist, celebrity and public intellectual. What makes Camus a philosopher as well? How was he shaped by his Algerian background? Does it make sense to call him an absurdist? How did he try to reconcile the very different parts of his extraordinary life?

The second life we explore in our series about the twentieth-century philosophers could not be more different from the first: David talks to philosopher Alex Carter about Simone Weil, who died aged just thirty-four and lived through much political and personal hardship, some of it self-inflicted. How did her asceticism inform her philosophical outlook? Why did she believe she needed to work in a factory and fight in the Spanish civil war to be true to her beliefs? When and how does her philosophy morph into theology? Was she a saint?   You can find out everything you need to know about this podcast – who we are, what we do, plus upcoming events and full lists of all episodes including PPF+ bonus episodes on our website https://www.ppfideas.com   Next time in The Lives of the Philosophers: Albert Camus Learn more about your ad choices.

Today we begin a new series exploring twentieth-century philosophy through the lives of the people behind the ideas. First up David talks to philosopher Nikhil Krishnan about A. J. Ayer, the man who helped inspire the rise and fall of logical positivism. What did Ayer discover about the nature of truth when he went to Vienna on his honeymoon? How did he manage to popularise such a technical approach to his subject? What was left of philosophy when he had finished with it? And what does Ayer’s taste for football, sex and celebrity tell us about his attitude to the life of the mind?

We come to the end of this series of bad ideas with a conversation with neurologist Suzanne O’Sullivan about the problems of living in an age of diagnosis, when all medical conditions need a label and new labels appear all the time. What happens when the classification criteria for conditions like autism and ADHD get broader and broader? Are doctors or patients driving this? When does predictive testing do more harm than good? Why does advocacy for sufferers get in the way of good health? Is de-diagnosis achievable?

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 know about this podcast – who we are, what we do, plus upcoming events and full lists of all episodes including PPF+ bonus episodes on our website https://www.ppfideas.com Next time in The History of Bad Ideas: Overdiagnosis Learn more about your ad choices.

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.

Today’s bad idea spans literature, film, pop culture and plenty else besides: David talks to literary critic and memoirist Catherine Taylor about what’s wrong with romantic heroes, from Byron and Heathcliff to James Dean and Jack Kerouac to Bridget Jones’s Mr Darcy and Andy Burnham. How did Romanticism give rise to the template for the brooding outsider who gets the girl? Which was the only Bronte sister to see through the myth? Why do romantic heroines get such a raw deal by comparison? And why does this idea lead to so much bad male behaviour?
