Melvyn Bragg examines how English republicanism has developed from Cromwell to the present day. Before the French Revolution, before the American Declaration of Independence, before Rousseau, Thomas Paine and Marx there was the English Revolution. In 1649 England executed its King - Charles Stuart - and declared itself a republic.But was republicanism a reaction to the fact of the dead absolutist king, a pragmatic response to an absence of ruler as many historians have thought, or was there republicanism already embedded as a sentiment deep within the culture of England? And where is it now? From the marching out onto the scaffold in Whitehall of Charles I and the subsequent loss of his head, while England gained a republic - what has republicanism meant for Britain? With Dr Sarah Barber, lecturer in the Department of History, Lancaster University and author of Regicide and Republicanism: Politics and Ethics in the English Revolution 1646-1659; Andrew Roberts, historian, journalist, conservative thinker and author of Salisbury: Victorian Titan.

Melvyn Bragg and guests discuss economic rights. Is democracy the truest conduit of capitalism, or do the forces that make us rich run counter to the democratic institutions that safeguard our rights? The economist Milton Friedman once said, “If freedom weren’t so economically efficient it wouldn’t stand a chance”. If that was ever true, is it still the case as we enter the era of the globalised economy? What is the relationship between democracy and capitalism? Is it possible for a country to get rich and stay rich without a liberal constitution and what is the prospect of the ever looming spectre of ‘globalised capital’ infringing human rights?With Professor Amartya Sen, Master of Trinity College, Cambridge and winner of the 1998 Nobel Prize in Economic Science; Will Hutton, former Editor of The Observer, Director of The Industrial Society and author of The State We’re In.

Melvyn Bragg and guests discuss childhood. The 20th Century was proclaimed the Century of the Child. It has been much else but in the western world the position, the possibilities, the meaning and the story of childhood have been changed, for many, monumentally. Children join the workforce much later, they are born into smaller, usually more affluent families than a hundred years ago, they tend to spend their parents’ money rather than contributing to the family coffers, they are handed over to the school for what used to be called the best years of their lives. Children have been involved in a spectacular journey in the last hundred years. St Paul wrote to the Corinthians: “When I was a child, I spake as a child, I understood as a child, I thought as a child: But when I became a man, I put away childish things”. But is it really as simple as that, can one always make such a clear distinction between childhood and being an adult, and is such a division even desirable?For most of this century - in the Western World - childhood has been another country with different laws and separate truths, it is something we either feel we missed or somewhere to which we long to return. Has it always been such a cherished state and do our endless machinations to keep childhood special actually help the individual? With Christina Hardyment, social historian and author of The Future of the Family; Dr Theodore Zeldin, Senior Fellow, St Anthony’s College, Oxford and author of An Intimate History of Humanity.

Melvyn Bragg and guests discuss progress. As man has grown in years and knowledge, has he also progressed in terms of happiness and a true understanding of the human condition? It was the Enlightenment which gave birth to the idea of the possibility of progress. The biblical account of time which had held sway until the eighteenth century was replaced by a conceit which put Man, not God, at the centre of the story of progress. But do we still believe in that story? Have we reached the end of history and the culmination of man’s evolution? Was the Argentinean writer Jorge Louis Borges right when he said “We have stopped believing in progress. What progress that is!”. Can our moral progress keep up with our material progress, be sober in a technologically inebriated world, be in any way more than a fig leaf covering the untameable old Adam whose tragedy - more Greek than Christian - has made and marred this century? Is there such a thing at all as moral progress, or have Darwin and Freud between them cut it out of the conceit of homo sapiens? With Anthony O’Hear, Professor of Philosophy, University of Bradford; Adam Phillips, psychoanalyst and author of Darwin’s Worms.

Melvyn Bragg and guests discuss the history and the modern purpose of education. Nobody - would argue with the fact that education is of central importance to the people we are. And there seems to be no doubt at all that fine skills, flexible life-long learning and cultivated intelligence are the keys to all our futures. So how do we tackle what was until recently - just two hundred years ago - a unique preserve of the few, the privileged or the plucked out exceptions? Plato made his priorities in education plain when he inscribed over the entrance to the Academy “Let no one ignorant of mathematics enter here”. He prized learning that revealed what he called “eternal reality, the realm unaffected by the vicissitudes of change and decay”, and this became the objective of education in Europe for thousands of years - vocational education, concrete skills, was hardly dreamed of. But was he right? What is education for: is its role to teach us the nature of reality, or to give us the tools to deal with it?With Mary Warnock, philosopher and educationalist; Ted Wragg, Professor of Education, University of Exeter.

Melvyn Bragg and guests discuss the widespread and chilling atrocities of the 20th century. Just over a hundred years ago, in the ‘Genealogy of Morals’, Nietzsche wrote “there can be no doubt that morality will gradually perish: this is the great spectacle in a hundred acts reserved for the next two centuries in Europe”. What if he is right? Certainly the twentieth century can claim the bitter palm of being the century with the biggest body count, the most advanced savagery, the finest of death delivery systems and, in that sense, the true Dark Ages of humankind. For inhumanity there has never been a century like it in the history of man: 58 million people died in the slaughter of two world wars. Stalinist Russia killed 20 million of its own people. The Nazis killed 6 million Jews. 2 million people were killed in Vietnam, 3 million in Korea, and in 1994 in Rwanda 1 million ordinary people were suddenly turned on and killed by their neighbours. And all the while in this bloody century the private and individual murder of one human by another has risen inexorably.What are the conditions that allow man to be inhuman to man on such a scale? And can a scientific study of the mind ever uncover the routes of inhumanity or evil?With Jonathan Glover, philosopher and Director of the Centre of Medical Law and Ethics, King’s College, London; Dr Gwen Adshead, consultant psychiatrist, Broadmoor Special Hospital.

Melvyn Bragg and guests discuss the history of the concept of the individual. The Renaissance gave birth to the concept of the individual. Shakespeare defined this individual in language which accepted the primacy of the male gender: “What a piece of work is a man! How noble in reason! How infinite in faculty! In form, in moving, how express and admirable! In action how like an angel! In apprehension how like a God!” According to Michel Foucault, French philosopher, polar opposite of Shakespeare and backed as he thought by Marx and Freud, our century killed the individual off. But has it? Was the individual born a mere six hundred years ago and has the century tolled its bell? And what is the individual?With Richard Wollheim, Professor of Philosophy, University of California in Berkeley; Jonathan Dollimore, Professor of English, York University.

Melvyn Bragg and guests discuss the Nation State. When we speak of our island story which island do we mean? When did England elide with Britain and why does it sit uneasily alongside the United Kingdom? At the end of the 20th century, the identity of one of the most forceful countries of the millennium is subject to scrutiny, doubt and criticism. What is England now? When did it act as England and not Britain, or the UK, or the British Isles? And how does its new role fit in with the idea of the Nation State which has dominated the internal and, more dramatically, the external behaviour of many powerful countries over the last few centuries? Yet despite its mighty past the Nation State itself can now seem powerless against the forces of globalisation. With Norman Davies, Emeritus Professor, London University and author of The Isles: A History; Andrew Marr, former editor of The Independent and author of Ruling Britannia: the Failure and Future of British Democracy.

Melvyn Bragg and guests discuss the concept of Utopia. Both the idea of, and the longing for a perfect society have been in our imagination for centuries, even millennia. Utopian dreams have driven fantasy, Fascism and fine feeling.Utopias, by definition, do not exist. The literal meaning of the Greek is “nowhere”. And yet, we are still enthralled by its allure. Why do some of us still believe in it - after the devastation wreaked this century by the utopian ideals that gave rise to Fascism and Communism? And what do utopias in fiction tell about the present - and even future?With Dr Anthony Grayling, human rights campaigner, lecturer in philosophy at Birkbeck College, London and Fellow of St Anne’s College, Oxford; John Carey, distinguished critic, journalist, broadcaster, Merton Professor of English, Oxford University and editor of, The Faber Book of Utopias.

Melvyn Bragg and guests discuss Africa. It could be seen as the great test of the West; economically, intellectually, spiritually. The "dark continent" was seen as a source of power for the West through its natural resources, a place of harvest for western religious missionaries, a prize area for anthropologists - a dark continent to be illuminated by our western lights. Now, darker, all but extinguished some think, by the attentions of its invaders, Africa is outside the take-up of the twentieth century it seems. But is this received view is merely clichéd and too easily pessimistic. With Professor Henry Louis Gates Jr, Chair of the Afro-American Studies Department, Harvard University and presenter of the BBC 2 series Into Africa; Anthony Sampson, writer, journalist and author of Mandela: The Authorised Biography.
