FAT is not an F-word! The radical practice of fat joy

Join Big Ideas host Natasha Mitchell with three women embracing the radical practice of finding joy in big bodies. Fat bodies are often stigmatised, stereotyped, shamed, medicalised, and politicised.

Hear why, for them, the personal is political. But can expectations to be fat and jolly become a burden too?

The dark side of collaboration — when thinking together goes wrong

At face value, collaboration sounds like a good thing: collaboration in the classroom, with colleagues, or between nations. But throughout history, collaboration was not always considered a virtuous act, and those who were identified as collaborators were shunned, humiliated or worse. This talk explores how people justify their involvement in wrongdoing, and how when collaboration devolves into conformity, it risks silencing dissent.This event was recorded at the Bundanon Art Museum.SpeakerDr Simon Longstaff — Executive Director, The Ethics Centre

The unbearable intimacy of voicing someone’s words — with Forced Entertainment

Words can mean everything, or nothing at all: it all depends on how they're delivered.

Safe at home – who profits when you’re afraid of your neighbours?

Your personal safety is big business, so much so that it’s given rise to “security capitalism”, a phenomenon where attempts to buy personal safety shape the world around us. As security becomes just another status symbol, do these gadgets make us safer or do they create a whole new list of anxieties – a self-fulfilling prophecy of perceived threat and risk aversion? This conversation 'Trapped: Does the security industry make us less safe?' was recorded at the CUNY Graduate Centre.

If it bleeds it leads – Bruce Shapiro on documenting the violence of modern life

From wars with global consequences to violent crimes in the suburbs, trauma underpins so much of the news cycle. It’s something award-winning journalist Bruce Shapiro came to understand intimately when, as a young crime reporter, he was stabbed. It changed his whole perspective on his profession, dedicating a large part of his career to the question of how trauma in yourself - or your source - changes the way you approach a story. Hear how trauma became newsworthy, how reporters learned to better tell those stories, and what it all means in 2025. The Annual Humanities Horizons Lecture is organised by Trinity Long Room Hub Arts and Humanities Research Institute at Trinity College Dublin, Ireland. The Lecture was established in 2013 to provide reflection on and advocacy for the Arts and Humanities. The content of the lecture is the intellectual property of the speaker Bruce Shapiro.

Australia and the spectre of war — from Vietnam to today

It's been 60 years since then Australian Prime Minister Robert Menzies sent Australians to fight in the Vietnam War. Since that time, the defence force has been involved in many armed conflicts and peace keeping missions around the world — but with varying degrees of public support. So how have successive Australian governments managed public consensus around military engagements? And with war once again a threat to global security, might they have to do so again?These events were recorded at the Robert Menzies Institute at the University of Melbourne on 29 April 2025, and at the Australian Catholic University on 11 April 2025.SpeakersSir Peter CosgroveFormer Chief of the Australian Defence ForceFormer Australian Governor GeneralGeorgina DownerChief Executive Officer, Robert Menzies Institute, University of MelbourneMia Martin HobbsAuthor, Return to Vietnam: An Oral History of American and Australian Veterans' JourneysPostdoctoral Research Fellow, School of Humanities and Social Sciences, Deakin University
