Is it always better to be just than unjust? That is the central question of Plato's Republic, discussed here by Melvyn Bragg and guests. Writing in c380BC, Plato applied this question both to the individual and the city-state, considering earlier and current forms of government in Athens and potential forms, in which the ideal city might be ruled by philosophers. The Republic is arguably Plato's best known and greatest work, a dialogue between Socrates and his companions, featuring the allegory of the cave and ideas about immortality of the soul, the value of poetry to society, and democracy's vulnerability to a clever demagogue seeking tyranny.With Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldMM McCabe Professor of Ancient Philosophy Emerita at King's College LondonandJames Warren Fellow of Corpus Christi College and a Reader in Ancient Philosophy at the University of Cambridge Producer: Simon Tillotson.

Melvyn Bragg and guests discuss Alexander Pushkin's verse novel, the story of Eugene Onegin, widely regarded as his masterpiece. Pushkin (pictured above) began this in 1823 and worked on it over the next ten years, while moving around Russia, developing the central character of a figure all too typical of his age, the so-called superfluous man. Onegin is cynical, disillusioned and detached, his best friend Lensky is a romantic poet and Tatyana, whose love for Onegin is not returned until too late, is described as a poetic ideal of a Russian woman, and they are shown in the context of the Russian landscape and society that has shaped them. Onegin draws all three into tragic situations which, if he had been willing and able to act, he could have prevented, and so becomes the one responsible for the misery of himself and others as well as the death of his friend.With Andrew Kahn Professor of Russian Literature at the University of Oxford and Fellow of St Edmund HallEmily Finer Lecturer in Russian and Comparative Literature at the University of St Andrewsand Simon Dixon The Sir Bernard Pares Professor of Russian History at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what, in C19th America's Gilded Age, was one of the most significant protest movements since the Civil War with repercussions well into C20th. Farmers in the South and Midwest felt ignored by the urban and industrial elites who were thriving as the farmers suffered droughts and low prices. The farmers were politically and physically isolated. As one man wrote on his abandoned farm, 'two hundred and fifty miles to the nearest post office, one hundred miles to wood, twenty miles to water, six inches to Hell'. They formed the Populist or People's Party to fight their cause, put up candidates for President, won several states and influenced policies. In the South, though, their appeal to black farmers stimulated their political rivals to suppress the black vote for decades and set black and poor white farmers against each other, tightening segregation. Aspects of the Populists ideas re-emerged effectively in Roosevelt's New Deal, even if they are mainly remembered now, if at all, thanks to allegorical references in The Wizard of Oz.The caricature above is of William Jennings Bryan, Populist-backed Presidential candidate.With Lawrence Goldman Professor of History at the Institute of Historical Research, University of LondonMara Keire Lecturer in US History at the University of OxfordAndChristopher Phelps Associate Professor of American Studies at the University of NottinghamProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and works of Christine de Pizan, who wrote at the French Court in the late Middle Ages and was celebrated by Simone de Beauvoir as the first woman to 'take up her pen in defence of her sex.' She wrote across a broad range, and was particularly noted for challenging the depiction of women by famous writers such as Jean de Meun, author of the Romance of the Rose. She has been characterised as an early feminist who argued that women could play a much more important role in society than the one they were allotted, reflected in arguably her most important work, The Book of the City of Ladies, a response to the seemingly endless denigration of women in popular texts of the time.The image above, of Christine de Pizan lecturing, is (c)The British Library Board.

Melvyn Bragg and guests discuss enzymes, the proteins that control the speed of chemical reactions in living organisms. Without enzymes, these reactions would take place too slowly to keep organisms alive: with their actions as catalysts, changes which might otherwise take millions of years can happen hundreds of times a second. Some enzymes break down large molecules into smaller ones, like the ones in human intestines, while others use small molecules to build up larger, complex ones, such as those that make DNA. Enzymes also help keep cell growth under control, by regulating the time for cells to live and their time to die, and provide a way for cells to communicate with each other.

Melvyn Bragg and guests discuss the flourishing of the idea of Purgatory from C12th, when it was imagined as a place alongside Hell and Heaven in which the souls of sinners would be purged of those sins by fire. In the West, there were new systems put in place to pray for the souls of the dead, on a greater scale, with opportunities to buy pardons to shorten time in Purgatory. The idea was enriched with visions, some religious and some literary; Dante imagined Purgatory as a mountain in the southern hemisphere, others such as Marie de France told of The Legend of the Purgatory of Saint Patrick, in which the entrance was on Station Island in County Donegal. This idea of purification by fire had appalled the Eastern Orthodox Church and was one of the factors in the split from Rome in 1054, but flourished in the West up to the reformations of C16th when it was again particularly divisive.WithLaura Ashe Associate Professor of English and fellow of Worcester College at the University of OxfordMatthew Treherne Professor of Italian Literature at the University of LeedsandHelen Foxhall Forbes Associate Professor of Early Medieval History at Durham UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and work of Louis Pasteur (1822-1895) and his extraordinary contribution to medicine and science. It is said few people have saved more lives than Pasteur. A chemist, he showed that otherwise identical molecules could exist as 'left' and 'right-handed' versions and that molecules produced by living things were always left-handed. He proposed a germ theory to replace the idea of spontaneous generation. He discovered that microorganisms cause fermentation and disease. He began the process named after him, pasteurisation, heating liquids to 50-60 C to kill microbes. He saved the beer and wine industries in France when they were struggling with microbial contamination. He saved the French silk industry when he found a way of protecting healthy silkworm eggs from disease. He developed vaccines against anthrax and rabies and helped establish immunology. Many of his ideas were developed further after his lifetime, but one of his legacies was a charitable body, the Pasteur Institute, to continue research into infectious disease.With Andrew Mendelsohn Reader in the School of History at Queen Mary, University of LondonAnne Hardy Honorary Professor at the Centre for History in Public Health at the London School of Hygiene and Tropical Medicineand Michael Worboys Emeritus Professor in the History of Science, Technology and Medicine at the University of Manchester Producer: Simon Tillotson.

To celebrate Melvyn Bragg’s 27 years presenting In Our Time, five well-known fans of the programme have chosen their favourite episodes. Comedian Frank Skinner has picked the episode on the life and work of the poet Emily Dickinson and recorded an introduction to it. (This introduction will be available on BBC Sounds and the In Our Time webpage shortly after the broadcast and will be longer than the version broadcast on Radio 4). Emily Dickinson was arguably the most startling and original poet in America in the C19th. According to Thomas Wentworth Higginson, her correspondent and mentor, writing 15 years after her death, "Few events in American literary history have been more curious than the sudden rise of Emily Dickinson into a posthumous fame only more accentuated by the utterly recluse character of her life and by her aversion to even a literary publicity." That was in 1891 and, as more of Dickinson's poems were published, and more of her remaining letters, the more the interest in her and appreciation of her grew. With her distinctive voice, her abundance, and her exploration of her private world, she is now seen by many as one of the great lyric poets.
