The Evolution of Crocodiles

Melvyn Bragg and guests discuss the remarkable diversity of the animals that dominated life on land in the Triassic, before the rise of the dinosaurs in the Jurassic, and whose descendants are often described wrongly as 'living fossils'. For tens of millions of years, the ancestors of alligators and Nile crocodiles included some as large as a bus, some running on two legs like a T Rex and some that lived like whales. They survived and rebounded from a series of extinction events but, while the range of habitats of the dinosaur descendants such as birds covers much of the globe, those of the crocodiles have contracted, even if the animals themselves continue to evolve today as quickly as they ever have.

Extra Terrestrials

Extra Terrestrials

Melvyn Bragg examines Extra Terrestrials. New planets have been observed far beyond our solar system and telescopes are being built that will enable us to look for water and oxygen on these distant planets. If water and oxygen are present, there is every reason to suppose that some form of life might also exist there. It has even been suggested that we might find life within our own solar system. One of Jupiter’s moons, Europa, appears to be covered in an ice-crusted ocean and there is evidence that water once flowed on Mars. On our own planet, there are forms of life that don’t need the sun, living instead on energy from volcanic vents on the ocean floor. This discovery has changed our concept of what life needs in order to survive. Could life only exist on another planet like ours and what are our chances of ever discovering such a planet? If we find life, will it be intelligent, or little more than green slime? And if intelligent aliens exist, why aren’t they here?

The Artist

The Artist

Melvyn Bragg and guests discuss the history of the artist. The sculptors who created the statues of ancient Greece were treated with disdain by their contemporaries, who saw the menial task of chipping images out of stone as a low form drudgery. Writing in the 1st century AD the Roman writer Seneca looked at their work and said: "One venerates the divine images, one may pray and sacrifice to them, yet one despises the sculptors who made them". Since antiquity artists have attempted to throw off the slur of manual labour and present themselves as gifted intellectuals on a higher level than mere artisans or craftsmen. By the Romantic period Wordsworth claimed that poets were 'endowed with a greater knowledge of human nature and a more comprehensive soul than are supposed to be common in mankind'. How did the artist become a special kind of human being? What role did aristocratic patronage of the arts play in changing the status of the artist? And how have we constructed the image of the artist? With Emma Barker, Lecturer in Art History, The Open University; Thomas Healy, Professor of Renaissance Studies at Birkbeck University of London; Tim Blanning, Professor of Modern European History at the University of Cambridge.

Marriage

Marriage

Melvyn Bragg and guests discuss the history of marriage.‘To have and to hold from this day forward, for better for worse, for richer for poorer, in sickness and in health, to love and to cherish, till death us do part.’ These marriage vows have been recited at church weddings since 1552, whenever two individuals have willingly pledged to enter into a relationship for life. But before the wedding service was written into the Book of Common Prayer, marriages were much more informal: couples could simply promise themselves to one another at any time or place and the spoken word was as good as the written contract. The ancients permitted polygamy and the taking of concubines so how did monogamy come to be the favoured mode in the West? Were procreation, financial stability, companionship, or love the reasons to get married? And what role has the state and the church played in legislating on personal affairs? With Janet Soskice, Reader in Modern Theology and Philosophical Theology, Cambridge University; Frederik Pedersen, Lecturer in History, Aberdeen University; Christina Hardyment, Social historian and journalist.

The Buddha

The Buddha

Melvyn Bragg and guests discuss the life and teachings of The Buddha. Two and a half thousand years ago a young man meditated on life and death and found enlightenment. In that moment he saw his past lives spread out before him and he realised that all life, indeed the very fabric of existence, was made of suffering. That man was Siddhartha Gautama but we know him as The Buddha. He taught us that we have not one but many lives and are constantly reborn in different forms according to the laws of Karma: an immortality that binds us to a cosmic treadmill of death, decay, rebirth and suffering from which the only escape is Nirvana. Buddhism was quickly established as a major religion in South East Asia but now two millenia later it is one of the fastest growing religions of the Western world. Why has it captured the spirit of our times? Is it because there is no compulsion to believe in God? And what is it that Western converts hope to get from Buddhism - truth and enlightenment or simply a spiritual satisfaction that Western religion cannot provide? With Peter Harvey, Professor of Buddhist Studies at the University of Sunderland; Kate Crosby, Lecturer in Buddhist Studies, SOAS; Mahinda Deagallee, Lecturer in the Study of Religions, Bath Spa University College and a Buddhist Monk from the Theravada tradition in Sri Lanka.

Milton

Milton

Melvyn Bragg examines the literary and political career of the poet John Milton. If it wasn't for the poet Andrew Marvell we wouldn't have his later works; Paradise Lost, Paradise Regained and Samson Agonistes. Milton spent the English Civil Wars as a prominent politician and right hand man to Oliver Cromwell. When the Monarchy was restored in 1660 it was only Marvell's intervention that saved Milton from execution. By then, Marvell argued, Milton was old and blind and posed no threat to Charles II. But as a young man Milton had been an activist and pamphleteer extraordinaire. Allegedly inspired by a meeting with Galileo he wrote in passionate defence of Liberty. He detested the Church's insistence on empty ritual. And most dramatically for his time he demanded that the state serve its people rather than the people serve the state. How then should we remember Milton - as poet or politician - as an idealist or an apologist for a revolutionary yet intolerant regime? And was he a man at one with the people or an elitist who preached to the masses but lived his own life only in the most rarefied of circles? With John Carey, Emeritus Professor of English Literature at Oxford University; Lisa Jardine, Professor of Renaissance Studies at Queen Mary College, University of London and Honorary Fellow of King's College Cambridge; Blair Worden, Professor of Early Modern History at the University of Sussex.

Virtue

Virtue

Melvyn Bragg and guests discuss the history of virtue. When Socrates asked the question ‘How should man live?’ Plato and Aristotle answered that man should live a life of virtue. Plato claimed there were four great virtues - Temperance, Justice, Prudence and Courage and the Christian Church added three more - Faith, Hope and Love. But where does the motivation for virtue come from? Do we need rules to tell us how to behave or can we rely on our feelings of compassion and empathy towards other human beings? Shakespeare’s Iago says “Virtue! A fig! ‘tis in ourselves that we are thus or thus. Our bodies are our gardens to the which our wills are gardeners. ” So is virtue a character trait possessed by some but not others? Is it derived from reason? Or does it flow from the innate sympathies of the human heart? For the last two thousand years philosophers have grappled with these ideas, but now in the twenty first century a modern reappraisal of virtue is taking the argument back to basics with Aristotle. With Galen Strawson, Professor of Philosophy at the University of Reading; Miranda Fricker, Lecturer in Philosophy at Birkbeck, University of London; Roger Crisp, Uehiro Fellow and Tutor in Philosophy at St Anne's College, Oxford.

The Celts

The Celts

Melvyn Bragg and guests discuss the Celts. Around 400 BC a great swathe of Western Europe from Ireland to Southern Russia was dominated by one civilisation. Perched on the North Western fringe of this vast Iron Age culture were the British who shared many of the religious, artistic and social customs of their European neighbours. These customs were Celtic and this civilisation was the Celts.The Greek historians who studied and recorded the Celts' way of life deemed them to be one of the four great Barbarian peoples of the world. The Romans wrote vivid accounts of Celtic rituals including the practice of human sacrifice - presided over by Druids - and the tradition of decapitating their enemies and turning their heads into drinking vessels.But what were the Celts in Britain really like? Was their apparent lust for violence tempered by a love of poetry and beautiful art? How far should we trust the classical historians in their writings on the Celts? And what can we learn from the archaeological remains that have been discovered in this country? With Barry Cunliffe, Professor of European Archaeology at Oxford University; Alistair Moffat, Historian and author of The Sea Kingdoms - The Story of Celtic Britain and Ireland; Miranda Aldhouse Green, Professor of Archaeology at the University of Wales.

Anatomy

Anatomy

Melvyn Bragg examines the history of mankind's quest to understand the human body. The Greeks thought we were built like pigs, and when Renaissance man first cut his sacred flesh it was an act of heresey. We trace the noble ambitions of medical science to the murky underworld of Victorian grave robbing, we trace 2000 years of anatomical study. From the great showman Vesalius, enthralling the Renaissance Artists in the operating theatres of Italy to the sad and gruesome pursuits of Burke and Hare, Anatomy is mankind's often frustrated attempt to understand the body of man. What role has science, religion and art played in the quest to understand the male and the female body?With Harold Ellis, Clinical Anatomist, School of Biomedical Sciences, King's College, London; Ruth Richardson, Historian, and author of Death, Dissection and the Destitute, Phoenix Press; Andrew Cunningham, Wellcome Trust Senior Research Fellow in the History of Medicine, Department of History and Philosophy of Science, Cambridge University.
