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

Alec Ryrie was Gresham Professor of Divinity. He is also Professor of the History of Christianity at Durham University, Co-Editor of the Journal of Ecclesiastical History and President of the Church of England Record Society. From 2015-17 he was Visiting Professor in the History of Religion at Gresham College and gave two series of lectures on the history of Protestant Christianity. In 2019 he was elected a Fellow of the British Academy.

He studied History as an undergraduate, at Trinity Hall, Cambridge, before completing a Master's in Reformation Studies at St. Andrews and a D.Phil. in Theology at St. Cross College, Oxford. From 1999-2006 he taught at the University of Birmingham, moving to Durham in 2007. He was Head of the Department of Theology and Religion from 2012-15 and a Leverhulme Major Research Fellow from 2015-18. He is on the editorial boards of St Andrews Studies in Reformation History (Ashgate) and the Royal Historical Society's New Historical Perspectives. Since 1997 he has been a Reader in the Church of England, and he is licenced to the parish of Shotley St. John (diocese of Newcastle).

Professor Ryrie is a historian of the Reformation era and of Protestantism more widely, with a particular focus on England and Scotland in the sixteenth and seventeenth centuries. He is an expert on the emergence and development of Protestant and radical beliefs, identities and spiritualities, and on the history of Protestant missions and missionaries. He has written several prize-winning books and his 2017 book Protestants: The Radicals Who Made the Modern World gives an overview of the history of Protestantism from Luther to the present. Much of the book was prefigured in his lectures at Gresham College in 2015-17. His Gresham lectures from 2018-19 presented aspects of his 2019 book Unbelievers: An Emotional History of Doubt; his Gresham lectures from 2020-1 presented aspects of his 2020 book The English Reformation.

His lectures on the early global spread of Protestantism form the basis of his forthcoming book The World’s Reformation, due to be published in 2026. Meanwhile, in 2025 he published The Age of Hitler and How We Will Survive It, and will be speaking about its themes at Gresham in September 2025.’

How will it all end? Predicting the far future of our Universe depends on understanding its present. This lecture starts with what seems to be a paradox in modern cosmology: that we have a model that does a fantastic job of explaining what we see, but which says 95% of the Universe is in forms (dark matter and dark energy) that we don’t understand. From there, we get a quick tour of the next 100 billion years – and speculate how the Universe’s end may hold the secrets of its beginnings.

This lecture was recorded by Chris Lintott on the 24th of September 2025 at Conway Hall, London

Professor Chris Lintott is a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.

Having been educated at Magdalene College, Cambridge and University College London, his research now ranges from understanding how galaxies form and evolve, to using machine learning to find the most unusual things in the Universe, to predicting the properties of visiting interstellar asteroids. He was the founder of the Zooniverse citizen science platform, which provides opportunities for more than two million online volunteers to contribute to scientific research, and which was the topic of his first book, 'The Crowd and the Cosmos’. His latest book is ‘Our Accidental Universe’. 

Professor Lintott is best known for presenting the BBC's long-running Sky at Night program, and as an accomplished lecturer. Away from work, he cooks, suffers through being a fan of Torquay United and Somerset cricket, and spends time with a rescued lurcher, Mr Max.

“Scary”, “Worried”, “Dangerous” were some of the most frequent words to describe AI in a recent UK Government public survey. Do you fear, as many do, that AI will lead to us becoming second-class entities? In this first lecture, we will explore this ascendency, considering how notions of intelligence, sentience, perception, consciousness and reasoning are being framed and challenged in an AI-centred world; and surface the social, economic and ethical implications of these developments.

This lecture was recorded by Professor Dominic Broomfield-McHugh on 23rd September 2025 at Barnard's Inn Hall, London.

Matt Jones is a computer scientist at Swansea University - and a Fellow of the British Computer Society - who works alongside colleagues from many other disciplines and directly with everyday folk across the world to explore the future of digital technologies.

Written in the era of the founding of Gresham College, Shakespeare’s A Midsummer Night’s Dream portrays the hypnotic dreaminess of a fairy world in which the real and the fantastic are blurred. This lecture explores how the innate musicality of Shakespeare’s original has provoked adaptations across the centuries, including Ashton and Balanchine’s ballets based on Mendelssohn’s incidental music for the play, Britten’s opera, Purcell’s masque The Fairy Queen, Henze’s Eighth Symphony and Elvis Costello’s Il Sogno. What is it about Shakespeare’s fairies that have inspired such diverse musical responses?

This lecture looks at the evolution of Guantánamo Bay, first as a focal point of Haitian immigration in 1991 (Gitmo 1.0), to the more famous detention of terror suspects in 2002 (Gitmo 2.0), and back to immigration in 2025. We will explore how Gitmo 3.0 is probably already over, and how we were able to head it off so quickly through legal challenges. However, Secretary of State Marco Rubio has said the U.S. is “actively searching” for countries to accept migrants deported from the U.S., with both El Salvador and Rwanda under consideration. We will discuss how lessons from legal action around Guantánamo Bay might translate to other settings.

The reflection of my right hand in a mirror is a left hand that looks similar yet is very different from the right. Many natural structures such as proteins, climbing vines, and seashells exhibit the same property known as chirality. Some of these objects are clearly left-handed, some are right-handed, some are both. The ultimate origin of chirality is one of Nature's great mysteries. In this talk, I will discuss the general problem of determining the chirality of an object and how it impacts all branches of science.

Planet Earth is an intricate and interconnected system, with some fundamental rules that we usually ignore. But we are part of our planet, not separate to it or just perched on top of it. This lecture will consider the two primary rules of Earth: that energy continually flows through the system (in from the Sun and then out again to space) and that matter/atoms must be continually recycled and use these to build up an outsider’s view of our planet.

This lecture was recorded by Helen Czerski on the 11th of September 2025 at Barnard's Inn Hall, London

Ever since modern economic growth began three centuries ago, people have suffered from periodic bursts of anxiety about the technologies of the time taking on the work that they do. This opening lecture explores the history of ‘automation anxiety’ – from the Luddites who smashed framing machines at the start of the Industrial Revolution in Britain to the protestors who set driverless cars on fire on the streets of San Francisco today. Time and again, their main worry – that there would not be enough work for people to do – turned out to be wrong. But they did have legitimate grievances as well.

In 1588, the young Galileo delivered some lectures that were impressive enough to secure him a mathematics professorship at the University of Pisa. His subject? The geometry of Dante’s Inferno. In this lecture we’ll look at some of Galileo’s deductions, and how the questions raised may have influenced his later mathematical research. Using this and other examples of creative work in mathematics that crosses our modern ideas of subject boundaries, I will argue that thinking across disciplines is not only intellectually exciting but academically vital.

This Annual Provost's Lecture was recorded by Sarah Hart on June 18th 2025 at Barnard's Inn Hall, London.

Sarah Hart was the first woman Professor of Geometry at Gresham College, and Acting Provost between March and October 2025. She is also Professor Emerita of Mathematics at Birkbeck, University of London.

Professor Hart studied at Oxford and Manchester, gaining her PhD in 2000. Postdoctoral research and teaching followed, including a prestigious Engineering and Physical Sciences Research Council Fellowship, before she was appointed to a lectureship at Birkbeck in 2004. She became Professor of Mathematics there in 2013, and served in various management roles including as Head of Mathematics and Statistics, Assistant Dean, and Programme Director for the MSc Mathematics.

Her academic publications have been mainly in the area of pure mathematics known as group theory, which has many applications both inside and outside of mathematics, for example in coding theory and cryptography. She is actively involved in the British Society for the History of Mathematics, and has served a three-year term as President of the Society from 2021-2023.

The lecture shares perspectives from global history, comparative politics, and international relations to revaluate whether the twentieth-century collapse of European colonialism was as definitive as often portrayed. It suggests that, while in some ways, ending European Empires remade our contemporary world, in others processes of decolonization are far from complete.

This lecture was recorded by Martin Thomas on the 9th of April 2025 at Barnard's Inn Hall, London

Martin is Professor of Imperial History and Director of the Centre for Histories of Violence and Conflict at the University of Exeter.
