The story of Jane Eyre is one of the best-known in English fiction. Jane is the orphan who survives a miserable early life, first with her aunt at Gateshead Hall and then at Lowood School. She leaves the school for Thornfield Hall, to become governess to the French ward of Mr Rochester. She and Rochester fall in love but, at their wedding, it is revealed he is married already and his wife, insane, is kept in Thornfield's attic. When Jane Eyre was published in 1847, it was a great success and brought fame to Charlotte Bronte. Combined with Gothic mystery and horror, the book explores many themes, including the treatment of children, relations between men and women, religious faith and hypocrisy, individuality, morality, equality and the nature of true love.

A moral theory that emphasises ends over means, Utilitarianism holds that a good act is one that increases pleasure in the world and decreases pain. The tradition flourished in the eighteenth and nineteenth centuries with Jeremy Bentham and John Stuart Mill, and has antecedents in ancient philosophy. According to Bentham, happiness is the means for assessing the utility of an act, declaring "it is the greatest happiness of the greatest number that is the measure of right and wrong." Mill and others went on to refine and challenge Bentham's views and to defend them from critics such as Thomas Carlyle, who termed Utilitarianism a "doctrine worthy only of swine."WithMelissa Lane The Class of 1943 Professor of Politics at Princeton UniversityJanet Radcliffe Richards Professor of Practical Philosophy at the University of OxfordandBrad Hooker A Professor of Philosophy at the University of ReadingProducer: Simon Tillotson.

In the Middle Ages, Prester John was seen as the great hope for Crusaders struggling to hold on to, then regain, Jerusalem. He was thought to rule a lost Christian kingdom somewhere in the East and was ready to attack Muslim opponents with his enormous armies. There was apparent proof of Prester John's existence, in letters purportedly from him and in stories from travelers who claimed they had met, if not him, then people who had news of him. Most pointed to a home in the earthly paradise in the Indies, outside Eden, with fantastical animals and unimaginable riches. Later, Portuguese explorers thought they had found him in Ethiopia, despite the mystified denials of people there. Melvyn Bragg asks why the legend was so strongly believed for so long, and what facts helped sustain the myths.WithMarianne O'Doherty Associate Professor in English at the University of SouthamptonMartin Palmer Director of the International Consultancy on Religion, Education, and CultureAndAmanda Power Senior Lecturer in Medieval History at the University of Sheffield.Producer: Simon Tillotson.

While glass items have been made for at least 5,000 years, scientists are yet to explain, conclusively, what happens when the substance it's made from moves from a molten state to its hard, transparent phase. It is said to be one of the great unsolved problems in physics. While apparently solid, the glass retains certain properties of a liquid. At times, ways of making glass have been highly confidential; in Venice in the Middle Ages, disclosure of manufacturing techniques was a capital offence. Despite the complexity and mystery of the science of glass, glass technology has continued to advance from sheet glass to crystal glass, optical glass and prisms, to float glasses, chemical glassware, fibre optics and metal glasses.With:Dame Athene Donald Professor of Experimental Physics at the University of Cambridge and Master of Churchill College, CambridgeJim Bennett Former Director of the Museum of the History of Science at the University of Oxford and Keeper Emeritus at the Science MuseumPaul McMillan Professor of Chemistry at University College LondonProducer: Simon Tillotson.

It is said that, in Britain from the 18th Century, copies of Josephus' works were as widespread and as well read as The Bible. Christians valued "The Antiquities of the Jews" in particular, for the retelling of parts of the Old Testament and apparently corroborating the historical existence of Jesus. Born Joseph son of Matthias, in Jerusalem, in 37AD, he fought the Romans in Galilee in the First Jewish-Roman War. He was captured by Vespasian's troops and became a Roman citizen, later describing the siege and fall of Jerusalem. His actions and writings made him a controversial figure, from his lifetime to the present day.WithTessa Rajak Professor Emeritus of Ancient History, University of ReadingPhilip Alexander Professor Emeritus of Jewish Studies, University of ManchesterAndMartin Goodman Professor of Jewish Studies, University of Oxford and President of the Oxford Centre for Hebrew and Jewish StudiesProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Cotton Famine in Lancashire from 1861-65. The Famine followed the blockade of Confederate Southern ports during the American Civil War which stopped the flow of cotton into mills in Britain and Europe. Reports at the time told of starvation, mass unemployment and migration. Abraham Lincoln wrote, "I know and deeply deplore the sufferings which the working-men of Manchester, and in all Europe, are called to endure in this crisis." While the full cause and extent of the Famine in Lancashire are disputed, the consequences of this and the cotton blockade were far reaching.WithLawrence Goldman Director of the Institute of Historical Research at the University of LondonEmma Griffin Professor of History at the University of East AngliaAndDavid Brown Senior Lecturer in American Studies at University of ManchesterProducer: Simon Tillotson.

Rabindranath Tagore was the first non-European to win a Nobel Prize for Literature. He has been called one of the outstanding thinkers of the 20th century and the greatest poet India has ever produced. His Nobel followed publication of Gitanjali, his English version of some of his Bengali poems. WB Yeats and Ezra Pound were great supporters. Tagore was born in Calcutta in 1861 and educated partly in Britain; King George V knighted him, but Tagore renounced this in 1919 following the Amritsar Massacre. A key figure in Indian nationalism, Tagore became a friend of Gandhi, offering criticism as well as support. A polymath and progressive, Tagore painted, wrote plays, novels, short stories and many songs. The national anthems of India and Bangladesh are based on his poems.

Melvyn Bragg and his guests discuss the Earth's Core. The inner core is an extremely dense, solid ball of iron and nickel, the size of the Moon, while the outer core is a flowing liquid, the size of Mars. Thanks to the magnetic fields produced within the core, life on Earth is possible. The magnetosphere protects the Earth from much of the Sun's radiation and the flow of particles which would otherwise strip away the atmosphere. The precise structure of the core and its properties have been fascinating scientists from the Renaissance. Recent seismographs show the picture is even more complex than we might have imagined, with suggestions that the core is spinning at a different speed and on a different axis from the surface.WithStephen Blundell Professor of Physics and Fellow of Mansfield College at the University of OxfordArwen Deuss Associate Professor in Seismology at Utrecht UniversityandSimon Redfern Professor of Mineral Physics at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the life and work of the 18th-century novelist, playwright and diarist Fanny Burney, also known as Madame D'Arblay and Frances Burney. Her first novel, Evelina, was published anonymously and caused a sensation, attracting the admiration of many eminent contemporaries. In an era when very few women published their work she achieved extraordinary success, and her admirers included Dr Johnson and Edmund Burke; later Virginia Woolf called her 'the mother of English fiction'.With Nicole Pohl Reader in English Literature at Oxford Brookes UniversityJudith Hawley Professor of Eighteenth-Century Literature at Royal Holloway, University of LondonandJohn Mullan Professor of English at University College London.

Melvyn Bragg and his guests discuss the life of Matteo Ricci, a Jesuit priest who in the 16th century led a Christian mission to China. An accomplished scholar, Ricci travelled extensively and came into contact with senior officials of the Ming Dynasty administration. His story is one of the most important encounters between Renaissance Europe and a China which was still virtually closed to outsiders.With Mary Laven Reader in Early Modern History at the University of CambridgeCraig Clunas Professor of the History of Art at the University of OxfordandAnne Gerritsen Reader in History at the University of Warwick Producer: Simon Tillotson.
