    Philosopher Roman Krznaric, author of History for Tomorrow: Inspiration from the Past for the Future of Humanity, The Good Ancestor, and founder of the Empathy Museum has been looking backwards to help us all find a way forward.

Join Roman with Big Ideas host Natasha Mitchell at the 2026 Byron Writers Festival to challenge the 'tyranny of the now' with an exciting view of history as a source of radical hope.

  4. Number 4: Bob Spitz on the Rolling Stones and why all great music is a threat

    From their earliest days as blues-obsessed kids living in freezing squalor, to the first taste of fame and the day they landed in the US and went stratospheric — and all the grit, glamour and gore in between. There are myriad revisions to the conventional narrative which underscore just how in control of their narrative the band has been up to now. But Bob Spitz got unique access to the group's friends and family. And he's sharing the details and examines a creative force whose power shows no signs of fading, over sixty years on. Presented at the Free Library of Philadelphia Speakers Bob SpitzAmerican journalist and author of Rolling Stones, The Biography Dan DeLucaPop music critic for the Philadelphia Inquirer

  5. Number 5: Should social media be banned for over-16s too!? The 2026 Beaker Street Festival Great Debate

    Interesting idea or nanny-state gone way too far? If babies weren't born to doom scroll, why do we think grown-ups are? Don't miss our hilarious annual battle of brains and bravado with two teams and Big Ideas' host Natasha Mitchell at the Beaker Street Festival: where science meets art. Australia was the first country in the world to ban under-16s from social media. France just struck down a push for the same. Are adults immune to all the harms of these platforms?
