Conflict and great power rivalries are on the rise, democracy is in retreat, and multilateral institutions created to maintain global cooperation appear increasingly toothless. So is the world as we've known it coming to an end? And if so, what will replace it?

From Rodrigo Duterte, to Narendra Modi, to Donald Trump, strongman leaders around the world are harnessing big tech to consolidate their power. Social media is also being used to energise and organise resistance movements, but is the bad increasingly outweighing the good?

If a stiff dose of medical misinformation is what you're after, look no further than the White House right now. And, on social media and in online forums, countless conspiracy theories reign supreme. In this "post-truth" era, has science lost its authority, or have we lost sight of what scientific proof actually involves? From debates over the origins of our species to conspiracies surrounding the origins of COVID19, Dr Elizabeth Finkel goes where others fear to tread to lift the lid on how science works. Join her with Big Ideas' host Natasha Mitchell at this event hosted by the Royal Society of Victoria and Black Inc Books.

The Beatles shook the world to its core in the 1960's and, to this day, new generations continue to fall in love with their songs and their story. At the heart of this phenomenon lies the dynamic between John Lennon and Paul McCartney. Few other musical partnerships have been rooted in such a deep, intense and complicated personal relationship. Ian Leslie uses the songs they wrote to trace the shared journey of these two compelling men before, during, and after The Beatles.

The world feels more dangerous and unpredictable, but with Australia wedged between our traditional ally, America, and our biggest trading partner, China, does our most expensive ever defence project make us more secure, or less?

A frank and impassioned plea for peace by Gareth Evans. As Australia's former Foreign Minister and former president of the International Crisis Group, he's spent most of his career forging real paths to peace globally. From Sudan to Gaza, Myanmar to Ukraine - who can we rely on to stop "forever" wars and genocides? Does Australia have a unique role to play? And what about the UN in its 80th year? It was created after the horror of World War 2 to keep the peace. Has it lost its way? The 2025 Brisbane Peace Lecture is presented by the United Nations Association of Australia, Brisbane - and includes responses by two key leaders from the Sudanese and Palestinian communities.

Primatologist Jane Goodall once said: "It actually doesn't take much to be a difficult woman. That's why there are so many of us." She spoke up. For all the species who go unheard, or unnoticed by humans. She was a giant in the global environmental movement. She first walked into the wild forests of Tanzania as a young woman with no science training and embarked on what is now the longest-running study of chimpanzees in their natural habitat. Her trailblazing fieldwork changed our understanding of other primates and the threat we pose to their continuing existence. It changed her. And it changed the world. At 91, she was still travelling the world right up until her last breath, to help give all other species theirs. She was deeply compassionate, and her campaigns deeply connected with people. Dr Jane Goodall joined Big Ideas host Natasha Mitchell to discuss hope in action the 2022 WOMADelaide Festival. This conversation was originally broadcast on ABC Radio National's Science Friction in May 2022.

Liberalism isn't just a political philosophy but the basis of a truly meaningful life. That's the bold statement of philosopher Alexandre Lefebvre, author of the forthcoming book Liberalism As A Way of Life. Should individuals be free to pursue their own passions and interests in life? Does liberalism mean more than freedom of speech and small government? You might not identify as a liberal, but are we in fact all liberals at heart? 

The Philosophy You Already Have — a Live Philosophy event was presented in Melbourne at the Sophia Club, from the creators of Aeon and Psyche magazines. Find out more here about the series.

Original broadcast on March 21, 2024
