School of Thought is the new weekly series from the Institute of Economic Affairs.

Each week Professor Syed Kamall sits down with a special guest to discuss an important contributor to liberal thought, ask why their work matters and what impact their ideas have had on the guest and on the world.

This week, Syed's guest is Dr. Eamonn Butler, Director of the Adam Smith Institute and author of 'School of Thought: 101 Great Liberal Thinkers', the IEA publication which inspired the series.

Originally recorded as a video, you can also watch the episode on YouTube.
