Gresham College Lectures

ChatGPT, the AI chatbot developed by OpenAI, was the fastest growing app in history. But this achievement, as sudden and remarkable as it might seem, was simply the most recent chapter in a fascinating story that has been unfolding for almost seven decades. This lecture explores the full history of the relationship between AI and work, and how economists have tried to make sense of it. It’s a jour...

One of the first executive orders issued by President Trump in January was EO 14164 designed to “restore the death penalty”, though actually aimed at far more (including making the prison conditions of those commuted by Biden reflect the “monstrosity” of their crimes). We will explore what this means for the 2,400 people on America’s death row, at the same time as reviewing the rising levels of in...

During the fifty years since the launch of the Viking spacecraft to Mars, our view of the red planet has changed from hostile desert to a world which was once covered in water, and which may just possibly sustain life. Lavishly illustrated with the latest images from the fleet of spacecraft that have explored our neighbour, this lecture considers how Mars’ fate, like that of Earth, was set in the...

This lecture looks at the 'surreal' art of the Early Netherlandish painter Jheronimus Bosch within its historical and cultural context. Although Bosch’s terrifying visions of sin, death, and the hereafter may appear surreal today, especially his highly imaginative depictions of devils, they were tied to the religious attitudes and moralising texts of the period, such as the Ars moriendi,...

Hecate started as the ruling goddess of the Asian region of Caria, and got taken over by the Greeks as the only one able to operate in every realm of the cosmos. This then gave her special responsibility for travellers, doorways and restless ghosts. That slowly darkened her image, so that she became associated with the night, the moon, and magicians. By the Roman period, she was the goddess of sor...

In this lecture, Tsang examines the strategic goals and direction of travel China’s supreme leader, Xi Jinping, has set for the country and its people. He highlights what China’s new de facto state ideology Xi Jinping Thought is in order to explain systematically Xi’s domestic and global ambitions. In short, what Xi seeks to do is to forge one country, one people, one ideology, one party and one l...

How should we get organised for our later years? With just a little preparation while we are fit and healthy, we can express our wishes for more difficult times. There are simple and positive options to be followed. Not just a will and lasting power of attorney, but simple steps to being independent longer, staying at home longer and enjoying life longer. A little thought now, and hopefully with d...

Laughter is an incredibly powerful and yet mysterious emotion. We laugh with delight, but also surprise. We laugh at jokes, but also at embarrassment. Why? What subconscious signal is laughter intended to display? Why do we laugh when someone tickles us and what should we make of the fact that rodents do it too? And why is it that people’s sense of humour differs wildly and yet some drugs can send...

Watch the Q&A session here: https://youtu.be/Lv5h-Pp1r6s Looking at the plant world, one discovers beautiful and fascinating structures in the shape and arrangement of leaves, stems and roots. Some are simple and symmetric, other features are arranged in elegant Fibonacci spirals, yet others exhibit fractal-like patterns. How are these structures created with such regularity and reproducibilit...

Wittgenstein wrote: “If a lion could talk, we would not understand it”. That is, as lions and humans are not of the same material, they could not say anything meaningful to each other. AI is not like us; the only way we can have a relationship with it is for us to become like it. We will look at how digital services are already making us machine-like; and, we explore how advanced AI-human fusions...

Limitarianism holds that it is immoral to have personal wealth above a certain level. Is this idea compatible with capitalism? Defenders of capitalism have argued that it is not, whereas those who want to move beyond capitalism have urged defenders of limitarianism to clear up this issue. This lecture argues that limitarianism is compatible with some forms of capitalism, and that it would help the...

In this lecture, Mark Taubert, who chairs the national DNACPR policy for Wales, and is a palliative care clinician, reviews current practices. He will encourage you to consider your own end of life care advance care plan, and attempt to write down your prior wishes. He reviews recent concerns, scandals and media outputs and looks at current resuscitation policies, guidelines and resources. He also...

Pan started as a shepherds’ god in a wild and backward area of Greece, but became one of the best-known in the Greek and Roman world. This was partly because the leading city of Athens imported him as a saviour, and partly because he came to represent the freedom, peace and simplicity of the countryside to urban people. He was the most earthy of Greek deities, summing up wild nature in its beauty...

Watch the Q&A session here: https://youtu.be/oQeUePfTrEQ The Royal Historical Society Colin Matthew Memorial Lecture. In April 1945, British forces liberated the Bergen-Belsen concentration camp and arrested its commandant, Josef Kramer. What followed was the first post-war trial for war crimes - a landmark event that captured the world’s attention. Although later eclipsed by the Nuremberg Tri...

China has important islands of technological excellence, even dominance, but these islands exist in a sea of macroeconomic imbalances and headwinds. Xi Jinping is adamant that by focusing on technology, and other aspects of national security, China can hold sway in the global system and determine global governance. Many western economists and even some in China are not so sure, choosing to wonder...

We often talk about living on a blue planet, but when we think we’re talking about the ocean we’re generally only discussing what’s in it: fish, whales, pollution and ships. But that is to miss the biggest story on Earth, because it’s the water itself that sets the scene for everything else. This lecture will outline how the ocean engine works – its internal anatomy, how the components move, and h...

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 unique...

Watch the Q&A session here: https://youtu.be/v0RoRG2YA-0 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...

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 pr...

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 identitie...

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...

Watch the Q&A session here: https://youtu.be/3LrIEG26m78 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 throu...

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...

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 kinshi...

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...
