On Liberty

On Liberty

Author: BBC Radio 4 February 12, 2026 Duration: 49:24

Journalist, author and historian Misha Glenny presents his first edition of In Our Time, succeeding Melvyn Bragg who retired from this role last summer. Misha and his guests discuss the landmark work On Liberty by John Stuart Mill, published in 1859 and the increasing recognition for his wife Harriet Taylor Mill's contribution. The subject matter of the essay is ‘civil or social liberty: the nature and limits of the power which can be legitimately exercised by society over the individual’ and it argues that the sole end for which mankind may interfere with the liberty of action of anyone is self-protection and even then only to prevent harm to others. This essay became enormously popular and a foundational text for liberalism.

In Our Time is a BBC Studios production


For anyone with a restless mind, the weekly In Our Time podcast from BBC Radio 4 offers a deep and engaging conversation across the vast terrain of human thought and experience. Host Misha Glenny guides a panel of distinguished academics, not in lecture format, but through a lively, accessible discussion where ideas genuinely collide and unfold. You might find yourself immersed in the complex legacy of a figure like Napoleon one week, and the next be untangling the scientific principles of photosynthesis or the philosophical arguments of the Enlightenment. The scope is deliberately broad, covering history, religion, culture, science, and philosophy, because understanding one often requires context from another. What you hear is the genuine process of exploration-the questions, the debates, and the connections made in real time by leading experts. It’s the kind of podcast that doesn’t just recount the Sack of Rome or the intricacies of Russian court politics, but examines why these moments mattered and how their echoes are still felt. The result is a consistently stimulating hour that treats listeners as curious equals, offering the intellectual satisfaction of following a great conversation to its illuminating conclusion.
