Thinking Allowed

In the Indian call centre or 'outsourcing' industry, workers are trained to emulate the American or British workers which they have replaced. They change their names, take on western accents and develop lifestyles organised around a foreign culture in a distant time zone. Laurie Taylor is joined by Henrietta Moore to talk to Shehzad Nadeem about his new study into the hybrid culture these Asian employees have created.

The British government is seeking to develop a way to accurately measure the happiness of the population. In France such a gauge already exists, but is happiness really the proper goal of life? The French philosopher Pascal Bruckner tells Laurie Taylor that happiness has become a burdensome duty, and that the wave of enthusiasm for pursuing the nebulous quality has the opposite effect of actually promoting unhappiness amongst those who seek it. Much better, says he, to accept that happiness as an unbidden and fragile gift, arrives only by grace and luck.

Every country in the Western world has abandoned the use of capital punishment in the name of civilisation and humanity. Yet in the USA, dozens of states and the Federal Government itself continue to execute criminals for certain crimes. Laurie Taylor talks to David Garland about his investigation into the US death penalty and how America has become a peculiar exception in a world which is moving towards abolition. They are joined by former Director of Public Prosecutions, Ken (Lord) MacDonald.

Sexual Intercourse began in I963, according to Philip Larkin's 'Annus Mirabilis'. But what of the dark ages before the sexual revolution? A new study shows them to be not quite as repressed, unfulfilled and pitiable as many have been keen to cast them. In this edition Laurie talks to Kate Fisher and Simon Szreter about their illuminating exploration of intimate life in England between 1918 and 1963, which involved them speaking frankly and in depth to almost a hundred people about their sex lives in the period.

With a culture which equated health with beauty, Brazil has developed the biggest cosmetic surgery industry in the world. Public clinics often offer classic cosmetic procedures for free and 'La Plastica' is the realisable aim of people who can sometimes not afford the bus fair to make their consultation. How has plastic surgery become such an important part of the Brazilian culture and economy, and why is beauty seen as a 'right' for people who may not have electricity or running water. Laurie talks to Monica Figuero from Newcastle University and Alex Edmonds who's written on this subject.

Britain and Ireland have always lagged far behind the rest of Western Europe in terms of second home ownership. But, MPs apart, there is a relentless upsurge in people owning more than one residence. In a new report Chris Parks has analysed the effect of the increase of home ownership on British and Irish society and compared it with other parts of the world. He discusses his findings with Susan Smith and Laurie Taylor.

People have often referred to conflicts between the concepts we use to understand the best way to live - ideas like Liberty, Equality, Justice, Democracy. You need to suppress one to achieve the other, and this - the argument goes - proves that they are not universal moral concepts. In his engagingly titled new book, Justice for Hedgehogs, the US philosopher Ronald Dworkin seeks to show that there is no incompatibility between these ideas because they are part of a single unified value, they only appear to conflict because of the way we are looking at them. But how do we ascribe this value with a universal role without recourse to God, or some other metaphysical entity? Laurie discusses the idea with Ronald Dworkin and AC Grayling.

Committing crime in West Belfast carries a double jeopardy. As well as the police, there are the paramilitaries to look out for. Between 1973 and 2007 there were two and a half thousand shootings and beatings attributed to republican paramilitaries as punishment attacks. Young people have been 'tarred and feathered', had their legs broken, hundreds have been 'knee-capped' and a few have been 'executed' - i.e. murdered - in response to what they are assumed to have done. For three years at the height of this practice Heather Hamill lived and worked in the Catholic Community of West Belfast to research the pseudo-judicial process administered by the IRA. As punishment attacks are growing again, this time at the hands of dissident republican groups, she discusses paramilitary punishment attacks with Laurie and the criminologist Dick Hobbs.

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.
