The right to free expression is severely threatened in many places in the world, yet it has also never been so passionately defended. This lecture focuses on the recent history of banned literature. It considers the changing nature of literary censorship, arguments in defence of free expression, why literary writers have so frequently pushed the boundaries of the acceptable, and the impact of technology on censorship and free speech.

This lecture was recorded by Rachel Potter on 12th March 2025 at Barnard's Inn Hall, London.

Rachel Potter is Professor of Modern Literature at the University of East Anglia. She writes on literature and censorship, free expression and writers organisations, modernist literature and early twentieth century culture.

Offsets, politely called carbon credit markets, are essential to many net-zero strategies, yet  remain highly controversial. They seem an efficient solution for “unavoidable” emissions – but who decides what is unavoidable? This lecture will discuss several plans to achieve our climate goals, from emission compensation schemes to tackling fossil fuels by planting trees.

In this lecture we will discuss a hierarchy of rights. Is the American First Amendment the most important of all, given its five foundational rights – no establishment of religion; free exercise of religion; freedom of speech and the press; the right peaceably to assemble; the right to petition the Government for a redress of grievances. How might this apply to the UK?

Mapping the stars is, perhaps, the oldest of astronomical pursuits, but it has been perfected by the European Space Agency's Gaia mission, which is providing an exquisitely precise map showing the positions and movements of the nearest two billion stars. Starting with a history of mapping the cosmos, this lecture describes the new and dynamic history of our Milky Way galaxy that results, and will move to explaining the dynamic and growing nature of our galaxy.

It has become something of a cliché to say that data is the new oil. That isn’t the full story. For centuries it has proved itself to be infinitely re-usable. It has enabled the creation and reinforcement of collective memory. It has been documented in innumerable formats, from maps to databases, taxonomies, and infographics. We make sense of the world through the technology we use to process and visualise data. This lecture is an exploration of our enduring love for it.

Until the nineteenth century, the favourite ancient pagan gods in Western culture were those related to human qualities and activities. During that century, especially in Britain, attention switched to a horned divinity associated with the countryside and wild nature, usually personified as the Greek Pan. This lecture explores how and why this happened, and the impact on British culture, when the full subversive potential of this deity as a force for personal liberation became realised. It also shows how the image subsequently evolved from a classical god into an archetype.

Ronald is the Gresham Professor of Divinity.

Most of us rarely think about plant immunity. But, like us, plants can distinguish between different pathogens, trigger a ‘bespoke’ immune response and retain a memory of past infections to boost future immunity. However, plant immune systems also exhibit enviable features like the ability to inherit immunological memory from a parent, or to warn distant individuals of an impending pathogen attack. This lecture investigates how they do all of this and more without a single white blood cell.

Sophocles’ Antigone refers to “unwritten laws,” as does Thucydides’ Pericles. From the late fifth century BCE, the idea that laws are more effective when learned by memory and observation than when put into writing, forms a distinctive current in political reflections. Plutarch would even claim that the Spartan lawgiver Lycurgus had prohibited the writing down of his laws. This lecture will present Greek authors’ reflections on the interplay between writing and orality remain relevant to debates about ethical formation today.

As we navigate towns and cities, public spaces are all around us. These offer a respite from our often-busy routines. Public spaces are more than just the leftover areas between buildings; they depend on how interests are designed and negotiated, and its success is measured by the interactions that take place in it: the passage of the sun, the root of trees, and even the way they are used by children. However, these areas are constantly threatened by the way local and commercial funding invest in it.
Using recent projects, primarily in London and North America, this lecture will invite audiences to think about public space beyond the space between and around buildings; to view public spaces, their design and their constructions, under a new light.
