Events
To mark our centenary, the theme of the 2025/6 London Lecture Series, running from October 2025 to March 2026, is Philosophy in Retrospect and in Prospect. Distinguished philosophers have been invited to reflect on where their area of the discipline has got to over the last hundred years, and/or where it might go – or should go – over the next hundred.
See also our forthcoming Annual Symposium, and City Lectures.
Recordings of each talk will be available on TRIP’s YouTube Channel, where you can also see our archive of past events.

Our Programmes
London Lectures
Our flagship series of London Lectures deliver accessible evening talks from autumn to spring every year, with a different speaker each week.
Lectures from previous series are also available on the Royal Institute’s YouTube and podcast channels. Papers based on the Lectures are published in annual volumes by Cambridge University Press.
Annual City Lectures
Our annual lectures, which are open to the public free of charge, attract some of the world’s leading philosophers to share their thoughts on a topic of their choice. The lectures are held once a year in Cardiff, Dublin, Edinburgh and London. Recent lecturers include Heather Widdows, C. Thi Nguyen and Linda Martin Alcoff.
Annual Symposium
Written over 2000 years ago, Plato’s Symposium – literally, a ‘drinking together’ – is the first example in the Western world of what we would now call a round table discussion. Though we don’t serve drinks, each year we continue that tradition by bringing together four philosophers to discuss a topic of fundamental importance today. Symposia are open to the public free of charge. Find out more and watch discussions from previous years.
