Melvyn Bragg and guests discuss whether 'happiness' means living a life of pleasure, or of virtue. It is an old question, and the Roman poet Horace attempted to answer it when he wrote; 'Not the owner of many possessions will you be right to call happy: he more rightly deserves the name of happy who knows how to use the gods's gifts wisely and to put up with rough poverty, and who fears dishonour more than death'. It seems a noble sentiment but for the Greek Sophist Thrasymachus this sort of attitude was the epitome of moral weakness: For him poverty was miserable, and happiness flowed from wealth and power over men, an idea so persuasive that Plato wrote The Republic in response to its challenge. What have our philosophers made of the compulsion to be happy? And how much does this ancient debate still define what it means to be happy today? Are we entitled to health, wealth and the pursuit of pleasure or is true contentment something else entirely? With Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Simon Blackburn, Professor of Philosophy at Cambridge University; Anthony Grayling, Reader in Philosophy at Birkbeck College, University of London.

Melvyn Bragg examines the philosophy of Confucius. In the 5th century BC a wise man called Kung Fu Tzu said, 'study the past if you would divine the future'. This powerful maxim helped form the body of ideas, which more than Buddhism, more than Daoism, more even than Communism has defined what it is to be Chinese. It is a philosophy that we call Confucianism, and as well as asserting the importance of learning from the past it embodies a respect for heirachy, ritual and parents.But who was Confucius, what were his ideas and how did they succeed in becoming the bedrock for a civilisation? With Frances Wood, Curator of the Chinese section of the British Library, Tim Barrett Professor of East Asian History at SOAS, the School of African and Oriental Studies at London University, and Dr Tao Tao Liu, Tutorial Fellow in Oriental Studies at Wadham College, Oxford University.

Melvyn Bragg and guests discuss the origins of democracy. In the Gettysburg Address Abraham Lincoln called it “Government of the people, by the people, for the people”, but the word democracy appears nowhere in the American Constitution; the French Revolution was fought for Liberté, Egalité and Fraternité and the most that Churchill claimed for it was that it was “the worst form of government except for all those other forms that have been tried from time to time.” The Athenian city state famously practised participatory democracy, but neither Plato nor Socrates approved, the Romans turned their back on the idea of ‘mob rule’ and it is not until the nineteenth century that it becomes even moderately respectable to call oneself a democrat.So how did democracy rise to become the most cherished form of government in the world? In this programme we hope to trace the history of an idea across the cultures and centuries of Europe and the Middle East. And at a time when ideals of democracy are being thrown into stark relief by world events, we hope to gain a greater understanding of where democratic ideals have come from.With Melissa Lane, University Lecturer in the History of Political Thought; David Wootton, Professor of Intellectual History at Queen Mary College, London; Tim Winter, Assistant Muslim Chaplain at Cambridge University where he is Lecturer in Islamic Studies.

Melvyn Bragg and guests discuss existentialism. Imagine being back inside the bustling cafes on the Left Bank of Paris in the 1930s, cigarette smoke, strong coffee and the buzz of continental voices philosophising about human responsibility and freedom. This kind of talk gave utterance to Existentialism. A twentieth century philosophy of everyday life concerned with the individual, and his or her place within the world. In novels, plays and philosophy, Existentialists try to work out the nature of our existence. As Roquentin says in Sartre’s novel ‘Nausea’, “To exist is simply to be there; what exists appears, lets itself be encountered, but you can never deduce it”.But where did these ideas come from? What do they really mean? And how have they impacted on our lives? With Dr A. C. Grayling, Reader in Philosophy at Birkbeck College, University of London; Christina Howells, Professor of French at the University of Oxford, fellow of Wadham College; Simon Critchley, Professor of Philosophy at the University of Essex and author of A Companion to Continental Philosophy.

Melvyn Bragg and guests discuss the concept of evil. When Nietzsche killed off God he had it in for evil as well: In Beyond Good and Evil, he constructed an argument against what he called the “herd morality” of Christianity, and he complained "everything that elevates an individual above the herd and intimidates the neighbour is henceforth called evil." Nietzsche claimed that it was a dangerous idea that distorted human nature, ‘evil’ was invented by the church and was a completely alien concept to the noble philosophers of the ancient world. Was he right, did Christianity really invent the idea of evil? And has the idea meant anything more than excessively bad? With Jones Erwin, Lecturer in Philosophy at the University of Limerick; Stephen Mulhall, Tutor in Philosophy at New College, Oxford University; Margaret Atkins, Lecturer in Theology at Trinity and All Saints College, University of Leeds.

Melvyn Bragg and guests discuss the philosophy of love. In Plato’s Symposium a character called Aristophanes tells a story about Love. He says that once, near the beginning of time, there were three types of human, one male, one female and one that was part man and part woman. Each human type had four hands and four feet and one head with two faces, and what they lacked in beauty they made up for in power and bravery - they even dared to attack the Gods. Zeus, as usual, lost his patience and resolved to split these creatures in half to diminish their strength and increase their numbers. His plan was that there would be more people to offer sacrifices but they’d be too weak to bother the Gods. However, with the split he inadvertently created us - lonely creatures forever searching for our other halves. Aristophanes explained to Socrates, “human nature was originally one and we were a whole, and the desire and pursuit of the whole is what we call love”. This is one version of love that still seems to have strange echoes in the culture of today, but how has the Western understanding of the Philosophy of Love developed since Plato? Has it always been about finding our ‘other half’? With Professor Roger Scruton, author of many books including Sexual Desire; Angie Hobbes, lecturer in philosophy at Warwick University; Thomas Docherty, Professor of English at the University of Kent.

Melvyn Bragg and guests discuss Humanism. On the 3rd January 106 BC Marcus Tullius Cicero, lawyer, politician, Roman philosopher and the founding father of Humanism was born. His academy, the Studia Humanitas taught ‘the art of living well and blessedly through learning and instruction in the fine arts’, his version of ‘humanitas’ put man not God at the centre of the world.Centuries later, Cicero’s teachings had been metamorphosed into ‘Classical Humanism’, a faith in the soft arts of the Greek world. But how did Cicero’s ideas become Renaissance ideals? How did a small Greek curriculum later become a world philosophy? The human centred creed is credited with giving us human rights and democracy but has also been blamed for the most unspeakable horrors of the modern age. Have his ideas been distorted through the centuries for political ends? And why do some contemporary thinkers think the Humanist tradition is responsible for Elitism, Sexism and even Nazism? With Tony Davies, Professor and Head of the Department of English, University of Birmingham and author of Humanism; Lisa Jardine, Professor of Renaissance Studies, Queen Mary College, University of London and Honorary Fellow of Kings College Cambridge; Simon Goldhill, Reader in Greek Literature and Culture at Kings College Cambridge.

Melvyn Bragg and guests discuss the history of Nihilism. The nineteenth-century philosopher, Friedrich 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”. And, with chilling predictions like these, ‘Nihilism’ was born. The hard view that morals are pointless, loyalty is a weakness and ‘truths’ are illusory, has excited, confused and appalled western thinkers ever since. But what happened to Nietzsche’s revolutionary ideas about truth, morality and a life without meaning? Existentialism can claim lineage to Nietzsche, as can Post Modernism, but then so can Nazism. With so many interpretations, and claims of ownership from the left and the right, has anything positive come out of the great philosopher of ‘nothing’?With Rob Hopkins, Senior Lecturer in Philosophy, University of Birmingham; Professor Raymond Tallis, Doctor and Philosopher; Professor Catherine Belsey, University of Cardiff.

Melvyn Bragg and guests discuss the Laws of Nature. Since ancient times philosophers and physicists have tried to discover simple underlying principles that control the Universe: In the 6th Century BC Thales declared “Everything is water”, centuries later Aristotle claimed that all of creation was forged from four elements, Newton more successfully laid down the Law of Universal Gravitation and as we speak, contemporary scientists are struggling to complete the task of ‘String Theory’ - the quest to find a single over-arching equation that unites all of physics, and can perhaps explain the organisation of everything in existence.But are the Laws of Physics really ‘facts of life’? Is what is true in physics, true in all areas of existence? Is it even true in other areas of physics?With Mark Buchanan, physicist and author of Ubiquity; Professor Frank Close, theoretical physicist and author of Lucifer’s Legacy: The Meaning of Asymmetry; Nancy Cartwright, Professor of Philosophy, LSE.

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.
