In Our Time

Melvyn Bragg and guests discuss how, in the Enlightenment, Immanuel Kant (1724-1804) sought to define the difference between right and wrong by applying reason, looking at the intention behind actions rather than at consequences. He was inspired to find moral laws by natural philosophers such as Newton and Leibniz, who had used reason rather than emotion to analyse the world around them and had id...

Melvyn Bragg and his guests discuss the Central Asian polymath al-Biruni and his eleventh-century book the India. Born in around 973 in the central Asian region of Chorasmia, al-Biruni became an itinerant scholar of immense learning, a master of mathematics, medicine, astronomy and many languages. He corresponded with the age's greatest scientist, Avicenna, and made significant contributions to ma...

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this fourth of his choices, we hear Melvyn Bragg and his guests discuss bird migration. Their topic includes why some birds migrate and others do...

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 b...

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 be...

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...

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 R...

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 o...

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 enriche...

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 t...

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 t...

Melvyn Bragg and guests discuss The Battle of Lincoln on 20th May 1217, when two armies fought to keep, or to win, the English crown. This was a struggle between the Angevin and Capetian dynasties, one that followed Capetian successes over the Angevins in France. The forces of the new boy-king, Henry III, attacked those of Louis of France, the claimant backed by rebel Barons. Henry's regent, Willi...

Melvyn Bragg and guests discuss the text and context of The Book of the Dead, also known as the Book of Coming Forth by Day, the ancient Egyptian collections of spells which were intended to help the recently deceased navigate the underworld. They flourished under the New Kingdom from C16th BC until the end of the Ptolemaic era in C1st BC, and drew on much earlier traditions from the walls of pyra...

The 13th-century English philosopher Roger Bacon is perhaps best known for his major work the Opus Maius. Commissioned by Pope Clement IV, this extensive text covered a multitude of topics from mathematics and optics to religion and moral philosophy. He is also regarded by some as an early pioneer of the modern scientific method. Bacon's erudition was so highly regarded that he came to be known as...

Melvyn Bragg discusses the life and times of Rosa Luxemburg (1871-1919), 'Red Rosa', who was born in Poland under the Russian Empire and became one of the leading revolutionaries in an age of revolution. She was jailed for agitation and for her campaign against the Great War which, she argued, pitted workers against each other for the sake of capitalism. With Karl Liebknecht and other radicals, sh...

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this fifth of his choices, we hear Melvyn Bragg and his guests discuss a key figure from quantum mechanics. Their topic is the life and ideas of...

Melvyn Bragg and guests discuss Katsushika Hokusai (1760-1849), the Japanese artist whose views of Mt Fuji such as The Great Wave off Kanagawa (pictured) are some of the most iconic in world art. He worked as Japan was slowly moving towards greater contact with the outside world, trading with China and allowing two Dutch ships to dock each year. From these ships he picked up new synthetic colours...

Melvyn Bragg and guests discuss what is often called one of the most significant battles in history. In 480BC in the Saronic Gulf near Athens, between the mainland and the island of Salamis, a fleet of Greek allies decisively defeated a larger Persian-led fleet. This halted the further Persian conquest of Greece and, at Plataea and Mycale the next year, further Greek victories brought Persian with...

Melvyn Bragg and guests discuss the high temperatures that marked the end of the Paleocene and start of the Eocene periods, about 50m years ago. Over c1000 years, global temperatures rose more than 5 C on average and stayed that way for c100,000 years more, with the surface of seas in the Arctic being as warm as those in the subtropics. There were widespread extinctions, changes in ocean currents,...

Melvyn Bragg and guests discuss Elizabeth Gaskell's novel North and South, published in 1855 after serialisation in Dickens' Household Words magazine. It is the story of Margaret Hale, who was raised in the South in the New Forest and London's Harley Street, and then moves North to a smokey mill town, Milton, in Darkshire. As well as Margaret's emotional life and her growing sense of independence,...

Melvyn Bragg and guests discuss the Kuiper Belt, a vast region of icy objects at the fringes of our Solar System, beyond Neptune, in which we find the dwarf planet Pluto and countless objects left over from the origins of the solar system, some of which we observe as comets. It extends from where Neptune is, which is 30 times further out than the Earth is from the Sun, to about 500 times the Earth...

Melvyn Bragg and guests discuss Seneca the Younger, who was one of the first great writers to live his entire life in the world of the new Roman empire, after the fall of the Republic. He was a Stoic philosopher, he wrote blood-soaked tragedies, he was an orator, and he navigated his way through the reigns of Caligula, Claudius and Nero, sometimes exercising power at the highest level and at other...

Melvyn Bragg and guests discuss the flourishing of maths in the early Islamic world, as thinkers from across the region developed ideas in places such as Baghdad's House of Wisdom. Among them were the Persians Omar Khayyam, who worked on equations, and Al-Khwarizmi, latinised as Algoritmi and pictured above, who is credited as one of the fathers of algebra, and the Jewish scholar Al-Samawal, who c...

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the Northamptonshire poet John Clare who, according to one of Melvyn's guests Jonathan Bate, was 'the greatest labouring-class poet that England has ever produced'. Clare worked in a tavern, as a gardener and as a farm labourer in the early 19th century and achieved his first literary success with Poems Descriptive of Rural Li...

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the political philosophy of Hannah Arendt. She developed many of her ideas in response to the rise of totalitarianism in the C20th, partly informed by her own experience as a Jew in Nazi Germany before her escape to France and then America. She wanted to understand how politics had taken such a disastrous turn and, drawing on...
