Do animals make music? Are the languages of whales and birds truly songs? To answer this, we must first understand what we mean by music as human animals—and how it might emerge across the animal kingdom. From Messiaen’s transcriptions of bird calls to the rhythmic gaits of horses echoing in the blues, we’ll hear how animal behaviours form an unwitting orchestra and explore whether music is uniquely human or a shared language with our animal cousins.

Why has automation anxiety – the fear that new technologies cause mass unemployment – proven wrong over the centuries? This lecture explores how technology affects the labour market. While new technologies can substitute for workers, reducing demand for their efforts at certain activities, they can also complement them, increasing demand for them to do activities that haven’t been automated. Historically, people have focused on the former, harmful force and underestimated – or ignored – the latter helpful force. Today, headlines all too often make the same mistake.

How might we change the way we – and all our leaders think – so that we never go to war? 

The war between Russia and Ukraine, as well as the conflict in Gaza, have galvanised thinking about, and action by, the bodies administering, the laws of war. 

National court processes - applying ‘universal jurisdiction’ for example – may bring international war criminals to justice. Informal processes can provide material capable of developing national laws and of providing evidence to assist the formal courts. But do these processes do anything to protect from future wars?

This lecture was recorded by Professor Geoffrey Nice on 21th October 2025 at Barnard’s Inn Hall, London.

Sir Geoffrey Nice KC has practised as a barrister since 1971.  He worked at the International Criminal Tribunal for the Former Yugoslavia – the ICTY – between 1998 and 2006 and led the prosecution of Slobodan Milošević, former President of Serbia.

Much of his work since has been connected to cases before the permanent International Criminal Court – Sudan, Kenya, Libya – or  pro bono for victims groups – Iran, Burma, North Korea – whose cases cannot get to any international court.  He works for several related NGO’s and lectures and commentates in the media in various countries on international war crimes issues.  He has been a part-time judge since 1984 sitting at the Old Bailey and has sat as judge in other jurisdictions, tribunals and inquiries.  Between 2009 and 2012 he was Vice-Chair of the Bar Standards Board, the body that regulates barristers.

When – and how – did Athenian democracy begin? There is no unambiguous answer to this question. This lecture explores one plausible origin: the popular uprising in 508 BCE overthrowing foreign invaders (who had previously expelled an Athenian-bred family of tyrants). In the aftermath of that revolution, the Athenians – led by Kleisthenes – reorganised their political system to foster new identities and interactions. As further political and social changes were made, Athenian democracy took shape in the imaginations of contemporaries and of later generations.

This lecture is about the meaning of China and being Chinese. It examines critically how the Chinese state, under the control of the Communist Party defines them. It highlights the historical reality that the Chinese Mainland, Hong Kong and Taiwan adopted different political systems. The Communist Party installed a powerful Leninist party-state on the Mainland. Laisses-faire British colonial rule gloomed Hong Kong people to desire democratization. Taiwan has become a vibrant democracy. This lecture address how such realities should influence how we understand China and Chineseness.

War's environmental legacies disproportionately burden the civilian populations left behind. While research focuses on combatant exposures, civilians face chronic contamination from heavy metals, chemical residues, unexploded ordnance, and asbestos, often exacerbated by disrupted infrastructure and psychological trauma. Framed through the exposome, this lecture highlights the need for greater research and policy focus on these long-term, low-level exposures and their impact on civilian health, advocating for remediation, care, and environmental justice.

How is mathematical knowledge recorded and preserved across generations? Contrary to the idea that mathematics itself is somehow ‘permanent’, in this talk we will explore heritage-making in mathematics, that is the people, institutions, and material objects that can give mathematical ideas longevity. We will explore the heritage-making found in two very different types of French nineteenth-century libraries: those of famous mathematicians and those of secondary schools. We will especially focus on how the recording – and forgetting – of mathematical ideas is influenced by their publishing, political, and intellectual contexts.

The natural world faces unprecedented threats, challenging historical perceptions of nature as inexhaustible. Photographer Tim Flach draws on his acclaimed works, including Endangered, More Than Human, and Birds, to reveal how photography transcends traditional wildlife representation. By employing critical anthropomorphism and human portraiture techniques, Flach’s images foster empathy and kinship with animals. Collaborating with social scientists, he illustrates how visual storytelling evokes emotional responses and inspires conservation action, showcasing the profound intersection of art, science, and social awareness in the Anthropocene.

Fear is one of the earliest emotions to have evolved. Most vertebrates – and possibly some invertebrates – show fear when they are threatened. At its most core, fear keeps us alive, helping us flee from predators or avoid dangerous environments. But why does this process sometimes backfire, leaving us paralysed by otherwise harmless phobias? And why do so many people deliberately seek out fearful situations, from horror movies to parachute jumps, when instinct tells us to do the opposite? Can understanding the biology of fear help us conquer it, or simply make us more vulnerable to its impact?

Since 1945 Hitler and the Nazis have been the Western world’s one fixed moral reference point: the way we know what evil is. But that consensus has always been more fragile than it felt, and now it is unravelling. This lecture will trace how we came to build our values around the memory of the Second World War, why that consensus isn’t enough to deal with our current predicaments – and why the resolution to all this might be more hopeful than you think. 

This lecture was recorded by Alec Ryrie on the 30th of September 2025 at Bernard's Inn Hall, London
