Sir Gawain and the Green Knight

Melvyn Bragg and his guests discuss the Victorian social reformer Octavia Hill.From the 1850s until her death in 1912, Octavia Hill was an energetic campaigner who did much to improve the lot of impoverished city dwellers. She was a pioneer of social housing who believed that there were better and more humane ways of arranging accommodation for the poor than through the state. Aided at first by her friend John Ruskin, the essayist and art critic, she bought houses and let them to the urban dispossessed. Octavia Hill provided an early model of social work, did much to preserve urban open spaces, and was the first to use the term 'green belt' to describe the rural areas around London. She was also one of the founders of the National Trust. Yet her vision of social reform, involving volunteers and private enterprise rather than central government, was often at odds with that of her contemporaries.With:Dinah BirchProfessor of English Literature and Pro-Vice Chancellor for Research at Liverpool UniversityLawrence GoldmanFellow in Modern History at St Peter's College, OxfordGillian DarleyHistorian and biographer of Octavia HillProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Bhagavad Gita.The Bhagavad Gita, a 700-verse section of the Sanskrit epic the Mahabharata, is one of the most revered texts of Hinduism. Written in around 200 BC, it narrates a conversation between Krishna, an incarnation of the deity, and the Pandava prince Arjuna. It has been described as a concise summary of Hindu theology, a short work which offers advice on how to live one's life.The Gita is also a philosophical work of great richness and influence. First translated into English in the 18th century, it was quickly taken up in the West. Its many admirers have included Mahatma Gandhi, whose passion for the work is one reason that the Bhagavad Gita became a key text for followers of the Indian Independence movement in the first half of the twentieth century.With:Chakravarthi Ram-PrasadProfessor of Comparative Religion and Philosophy at Lancaster UniversityJulius LipnerProfessor of Hinduism and the Comparative Study of Religion and Fellow of Clare Hall at the University of CambridgeJessica FrazierResearch Fellow at the Oxford Centre for Hindu Studies and Lecturer in Religious Studies at Regent's College, LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the dawn of the European Iron Age.In around 3000 BC European metalworkers started to make tools and weapons out of bronze. A complex trading network evolved to convey this valuable metal and other goods around the continent. But two millennia later, a new skill arrived from the Middle East: iron smelting. This harder, more versatile metal represented a huge technological breakthrough.The arrival of the European Iron Age, in around 1000 BC, was a time of huge social as well as technological change. New civilisations arose, the landscape was transformed, and societies developed new cultures and lifestyles. Whether this was the direct result of the arrival of iron is one of the most intriguing questions in archaeology.With:Sir Barry CunliffeEmeritus Professor of European Archaeology at the University of OxfordSue HamiltonProfessor of Prehistory at University College LondonTimothy ChampionProfessor of Archaeology at the University of SouthamptonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the medieval universities.In the 11th and 12th centuries a new type of institution started to appear in the major cities of Europe. The first universities were those of Bologna and Paris; within a hundred years similar educational organisations were springing up all over the continent. The first universities based their studies on the liberal arts curriculum, a mix of seven separate disciplines derived from the educational theories of Ancient Greece. The universities provided training for those intending to embark on careers in the Church, the law and education. They provided a new focus for intellectual life in Europe, and exerted a significant influence on society around them. And the university model proved so robust that many of these institutions and their medieval innovations still exist today.With:Miri RubinProfessor of Medieval and Early Modern History at Queen Mary, University of LondonIan WeiSenior Lecturer in Medieval European History at the University of BristolPeter DenleyReader in History at Queen Mary, University of London.Producer: Thomas Morris.

In the 500th edition of the programme, Melvyn Bragg and his guests discuss the philosophical idea of free will.Free will - the extent to which we are free to choose our own actions - is one of the most absorbing philosophical problems, debated by almost every great thinker of the last two thousand years. In a universe apparently governed by physical laws, is it possible for individuals to be responsible for their own actions? Or are our lives simply proceeding along preordained paths? Determinism - the doctrine that every event is the inevitable consequence of what goes before - seems to suggest so.Many intellectuals have concluded that free will is logically impossible. The philosopher Baruch Spinoza regarded it as a delusion. Albert Einstein wrote: "Human beings, in their thinking, feeling and acting are not free agents but are as causally bound as the stars in their motion." But in the Enlightenment, philosophers including David Hume found ways in which free will and determinism could be reconciled. Recent scientific developments mean that this debate remains as lively today as it was in the ancient world.With: Simon BlackburnBertrand Russell Professor of Philosophy at the University of CambridgeHelen BeebeeProfessor of Philosophy at the University of BirminghamGalen StrawsonProfessor of Philosophy at the University of ReadingProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the age of the Universe.Since the 18th century, when scientists first realised that the Universe had existed for more than a few thousand years, cosmologists have debated its likely age. The discovery that the Universe was expanding allowed the first informed estimates of its age to be made by the great astronomer Edwin Hubble in the early decades of the twentieth century. Hubble's estimate of the rate at which the Universe is expanding, the so-called Hubble Constant, has been progressively improved. Today cosmologists have a variety of other methods for ageing the Universe, most recently the detailed measurements of cosmic microwave background radiation - the afterglow of the Big Bang - made in the last decade. And all these methods seem to agree on one thing: the Universe has existed for around 13.75 billion years.With:Martin ReesAstronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of CambridgeCarolin CrawfordMember of the Institute of Astronomy and Fellow of Emmanuel College at the University of CambridgeCarlos FrenkDirector of the Institute for Computational Cosmology at the University of Durham.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Taiping Rebellion.In 1850 a Chinese Christian convert, Hong Xiuquan, proclaimed himself leader of a new dynasty, the Taiping Heavenly Kingdom. He and his followers marched against the ruling Qing dynasty, gathering huge support as they went. The ensuing civil war lasted fourteen years; around twenty million people lost their lives in a conflict which eventually involved European as well as Chinese soldiers. The Taiping Rebellion was arguably the most important event to befall China in the 19th century. Chinese nationalists and communists alike have been profoundly influenced by it, and historians believe it shaped modern China in the same way as the First World War shaped modern Europe.Rana MitterProfessor of the History and Politics of Modern China at the University of OxfordFrances WoodHead of the Chinese Section at the British LibraryJulia LovellLecturer in Chinese History at Birkbeck, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the work and influence of Maimonides.Widely regarded as the greatest Jewish philosopher of the medieval period, Maimonides was also a physician and rabbinical authority. Also known as Rambam, his writings include a 14-volume work on Jewish law, the Mishneh Torah, which is still widely used today, and the Guide for the Perplexed, a central work of medieval philosophy. Although undoubtedly a titan of Jewish intellectual history, Maimonides was also profoundly influenced by the Islamic world. He exerted a strong influence on later Islamic philosophy, as well as on thinkers ranging from Thomas Aquinas to Leibniz and Newton.With:John HaldaneProfessor of Philosophy at the University of St AndrewsSarah StroumsaAlice and Jack Ormut Professor of Arabic Studies and currently Rector at the Hebrew University of JerusalemPeter AdamsonProfessor of Ancient and Medieval Philosophy at King's College London.Producer: Thomas Morris.
