Many of our global problems - from climate change to terrorism - require international not local solutions. Yet the world is increasingly fractured by nationalism. The political scientist, David Held, has a new book which explores cosmopolitan values. He tells Laurie Taylor why we should regard ourselves as citizens of the world rather than members of nations. Also, should we take responsibility for our own health, bodies and nutrition? Steven Shapin, Professor of the History of Science, talks about Dietetics - a branch of traditional western medicine which sought to prevent illness rather than find a cure. Originating in the 2nd century it held that good health reflected a virtuous life. This moral approach to the body died out with the advent of modern science but may now be enjoying a revival.

The Daleks are obsessed with racial purity and dedicated to a policy of genocide: they represent the Nazis. The Jagrafess is a loathsome alien purveying useless information - which he has censored, rewritten and controlled: he represents a modern day media mogul. This is the theory of the US academic Marc Edward DiPaolo who has analysed the political content of five decades of Doctor Who. He finds that the Time Lord is a liberal, bohemian, pacifist environmentalist, and definitely anti-American. Is Doctor Who a closet radical? Laurie and Marc discuss the contention with journalist, broadcaster and some-time Dr Who script-writer Matthew Sweet. Also on the programme: Softening Masculinities. New research by Mark McCormac finds that British secondary school boys are far less restrictive in their behaviour than they used to be. It is okay to use conditioner, comment on someone's clothes, and even give each other a hug.

Laurie Taylor talks to Professor Russell Jacoby, Professor Ash Amin, Professor Barbara Graziosi and The Bishop of Whitby, Martin Warner, about whether we can imagine 'utopia' in the 21st century. In an age that some describe as filled with anxiety and uncertainty, are we breeding a kind of fatalism towards the future that excludes any notion of utopia? How indeed might we define and describe utopia? Can utopian ideas be not only practical and pragmatic but also democratic? When considering utopia where does religious faith and thinking intertwine with the secular world? Can we even talk about commonly held utopian ideals or are we condemned to imagine utopia only as fantasy, as an intellectual or artistic excerise that is, ultimately, futile.producer. Chris Wilson.
