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?

In today’s episode David talks to forensic anthropologist Sue Black about what happens when forensic science and forensic expertise end up on trial in the courtroom. When and how did scientists get involved in the business of criminal prosecution? What changed with the advent of DNA testing? Is the adversarial system the best way of testing scientific evidence? Can a jury distinguish between good science, bad science and junk science? And what might have gone wrong in the case of Lucy Letby?

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?

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?

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?

Today’s bad idea is one the United States has been stuck with for a long time: David talks to historian of America Adam Smith about the damage done by the idea of the electoral college. Why was it thought necessary by the Founders to have special electors between the voters and their choice of president? What made it a dead letter almost as soon as it was created? How has it served to distort or discredit electoral outcomes? When, if ever, will it be replaced and if so by what?

Today’s episode in the history of bad ideas is about one of the central ideas in modern philosophy: utilitarianism, or the view that what matters is the greatest happiness of the greatest number. David talks to philosopher Nikhil Krishnan about how something that sounds so intuitively unobjectionable can produce some extremely objectionable outcomes. What is utility and how do we measure it? Does being a utilitarian actually make you happier? Whose pleasure and pain gets to count? And what happens when killing an innocent person will save many others … should we do it?

Out tomorrow on PPF+: part two of this conversation in which David and Nikhil explore some of the political implications of utilitarianism from what it means for democracy to how it was used to justify colonialism.

Today’s bad idea is a pervasive political myth: the notion that what really matters at election time is political leadership. David talks to political scientist Jane Green about why leaders are less important than they – and we – tend to think. What does shape how people choose to vote? Why do we consistently overstate what leaders can do? Did Blair or Johnson or Starmer really ‘win’ their elections? Can Andy Burnham buck the trend?

David talks to historian and broadcaster Greg Jenner about the surprising history of the idea of celebrity, from Roman generals to 18th-century child stars to contemporary pop culture icons. How is celebrity different from fame or renown? What makes celebrity so seductive, so pervasive and, sometimes, so dangerous? Why are celebrity culture and commercial culture inextricably linked? And what are the lessons from the celebrity of Michael Jackson?
