In Our Time

Melvyn Bragg and guests discuss the history of Alchemy, the ancient science of transformations. The most famous alchemical text is the Emerald Tablet, written around 500BC and attributed to the mythical Egyptian figure of Hermes Trismegistus. Among its twelve lines are the essential words - “as above, so below". They capture the essence of alchemy, that the heavens mirror the earth and that all things correspond to one another. Alchemy was taken up by some of the most extraordinary people in our intellectual development, including Roger Bacon, Paracelsus, the father of chemistry, Robert Boyle, and, most famously, Isaac Newton, who wrote more about alchemy than he did about physics. It is now contended that it was Newton’s studies into alchemy which gave him the fundamental insight into the famous three laws of motion and gravity.With Peter Forshaw, Lecturer in Renaissance Philosophies at Birkbeck, University of London, Lauren Kassell, Lecturer in the History and Philosophy of Science at the University of Ca

Melvyn Bragg and guests discuss the Cambrian period when there was an explosion of life on Earth. In the Selkirk Mountains of British Columbia in Canada, there is an outcrop of limestone shot through with a seam of fine dark shale. A sudden mudslide into shallow water some 550 million years ago means that a startling array of wonderful organisms has been preserved within it. Wide eyed creatures with tentacles below and spines on their backs, things like flattened rolls of carpet with a set of teeth at one end, squids with big lobster-like arms. There are thousands of them and they seem to testify to a time when evolution took a leap and life on this planet suddenly went from being small, simple and fairly rare to being large, complex, numerous and dizzyingly diverse. It happened in the Cambrian Period and it's known as the Cambrian Explosion.But if this is the great crucible of life on Earth, what could have caused it? How do the strange creatures relate to life as we see it now? And what does the Cambrian Ex

Melvyn Bragg and guests discuss the mind/body problem in philosophy. At the start of René Descartes' Sixth Meditation he writes: "there is a great difference between mind and body, inasmuch as body is by nature always divisible, and mind is entirely indivisible. For when I consider the mind, or myself in so far as I am merely a thinking thing, I am unable to distinguish many parts within myself; I understand myself to be something quite single and complete. Although the whole mind seems to be united to the whole body, I recognize that if a foot or an arm or any other part of the body is cut off nothing has thereby been taken away from the mind".This thinking is the basis of what's known as 'Cartesian dualism', Descartes' attempt to address one of the central questions in philosophy, the mind/body problem: is the mind part of the body, or the body part of the mind? If they are distinct, then how do they interact? And which of the two is in charge?With Anthony Grayling, Reader in Philosophy at Birkbeck, Univers

Melvyn Bragg and guests discuss the assassination of Tsar Alexander II. On 1st March 1881, the Russian Tsar, Alexander II, was travelling through the snow to the Winter Palace in St Petersburg. An armed Cossack sat with the coach driver, another six Cossacks followed on horseback and behind them came a group of police officers in sledges. It was the day that the Tsar, known for his liberal reforms, had signed a document granting the first ever constitution to the Russian people.But his journey was being watched by a group of radicals called 'Narodnaya Volya' or 'The People's Will'. On a street corner near the Catherine Canal, they hurled the first of their bombs to halt the Tsar's iron-clad coach. When Alexander ignored advice and ventured out onto the snow to comfort his dying Cossacks, he was killed by another bomber who took his own life in the blast.Why did they kill the reforming Tsar? What was the political climate that inspired such extreme acts? And could this have been the moment that the Russian sta

Melvyn Bragg and guests discuss the rise and eventual downfall of the Roman Republic which survived for 500 years.Around 550 BC, Lucretia, the daughter of an aristocrat, was raped by the son of Tarquin, the King of Rome. Lucretia told her family what had happened to her and then in front of them, killed herself from shame. The Roman historian Livy describes what was believed to have happened next:"Brutus, while the others were absorbed in grief; drew out the knife from Lucretia's wound, and holding it up, dripping with gore, exclaimed, "By this blood, most chaste until a prince wronged it, I swear, and I take you, gods, to witness, that I will pursue Lucius Tarquinius Superbus and his wicked wife and all his children, with sword, with fire, aye with whatsoever violence I may; and that I will suffer neither them nor any other to be king in Rome!". The King was duly expelled from the city and the Roman Republic was founded and lasted for 500 years. But in what form did this republic evolve, what were its values

Melvyn Bragg and guests discuss the myth of Faustus." Was this the face that launch'd a thousand ships,And burnt the topless towers of Ilium?Sweet Helen, make me immortal with a kiss!Her lips suck forth my soul: see, where it flies!"So spoke Dr Faustus with unnerving prescience shortly before being dragged off to hell in Christopher Marlowe's historical tragedy. His Faustian pact with the devil Mephistopheles had granted him 24 years of limitless knowledge and power, but at the cost of his soul. His terrible story was told as a dire warning to anyone who would seek to reach beyond the limits of their human lot.Why is Goethe's Faust reprieved, when Marlowe's Faustus gets taken by Satan and what does the story's constant retelling tell us about society's changing attitudes to knowledge, ambition and hellish damnation? But who was the real Faust? Why has his story maintained a 400 year grip on the German and British imaginations, and how has his image changed as each generation embraced the myth?With Juliette Wo

Melvyn Bragg and guests discuss the Second Law of Thermodynamics which can be very simply stated like this: "Energy spontaneously tends to flow from being concentrated in one place to becoming diffused and spread out". It was first formulated – derived from ideas first put forward by Lord Kelvin - to explain how a steam engine worked, it can explain why a cup of tea goes cold if you don't drink it and how a pan of water can be heated to boil an egg.But its application has been found to be rather grander than this. The Second Law is now used to explain the big bang, the expansion of the cosmos and even suggests our inexorable passage through time towards the 'heat death' of the universe. It's been called the most fundamental law in all of science, and CP Snow in his Two Cultures wrote: "Not knowing the Second Law of Thermodynamics is like never having read a work of Shakespeare".What is the Second Law? What are its implications for time and energy in the universe, and does it tend to be refuted by the exist

Melvyn Bragg and guests discuss the political philosopher Niccolo Machiavelli. In The Prince, Machiavelli's great manual of power, he wrote, "since men love as they themselves determine but fear as their ruler determines, a wise prince must rely upon what he and not others can control". He also advised, "One must be a fox in order to recognise traps, and a lion to frighten off wolves. Those who simply act like lions are stupid. So it follows that a prudent ruler cannot, and must not, honour his word when it places him at a disadvantage".What times was Machiavelli living through to take such a brutal perspective on power? How did he gain the experience to provide this advice to rulers? And was he really the amoral, or even evil figure that so many have liked to paint him?With Quentin Skinner, Regius Professor of History at the University of Cambridge; Evelyn Welch, Professor of Renaissance Studies at Queen Mary, University of London; Lisa Jardine, Director of the Centre for Editing Lives and Letters at Queen M

Melvyn Bragg and guests discuss the extraordinary mind of the psychiatrist Carl Gustav Jung. In 1907 Sigmund Freud met a young man and fell into a conversation that is reputed to have lasted for 13 hours. That man was the Swiss psychiatrist Carl Gustav Jung. Freud is celebrated as the great pioneer of the 20th century mind, but the idea that personality types can be 'introverted' or 'extroverted', that certain archetypal images and stories repeat themselves constantly across the collective history of mankind, and that personal individuation is the goal of life, all belong to Jung: "Your vision will become clear only when you look into your heart... Who looks outside, dreams. Who looks inside, awakens", he declared. And he also said "Show me a sane man and I will cure him for you".Who was Jung? What is the essence and influence of his thought? And how did he become such a controversial and, for many, such a beguiling figure?With Brett Kahr, Senior Clinical Research Fellow in Psychotherapy and Mental Health at

Melvyn Bragg and guests discuss the Venerable Bede. In 731 AD, in the most far-flung corner of the known universe, a book was written that represented a height of scholarship and erudition that was not to be equalled for centuries to come. It was called the Ecclesiastical History of the Angle Peoples and its author was Bede. A long way from Rome, in a monastery at Jarrow in the North East of England, his works cast a light across the whole of Western Civilisation and Bede became a bestseller, an internationally renowned scholar and eventually a saint. His Ecclesiastical History has been in copy or in print ever since it was written in the eighth century and his edition of the Bible remains the Catholic Church's most authoritative Latin version to this day.How did Bede achieve such ascendancy from such an obscure part of Christendom? And what was so remarkable about his work?With Richard Gameson, Reader in Medieval History at the University of Kent at Canterbury; Sarah Foot, Professor of Early Medieval History

Melvyn Bragg and guests discuss the Higgs Boson particle. One weekend in 1964 the Scottish scientist Peter Higgs was walking in the Cairngorm Mountains. On his return to his laboratory in Edinburgh the following Monday, he declared to his colleagues that he had just experienced his 'one big idea' and now had an answer to the mystery of how matter in the universe got its mass. That big idea took many years of refining, but it has now generated so much international interest and has such an important place in physics that well over one billion pounds is being spent in the hope that he was right. It's the biggest science project on Earth; the quest to find the 'Higgs Boson', a fundamental constituent of nature that - if it does exist - has such a central role in defining the universe that it's also known as the God Particle.What is the Higgs Boson? Why is it so important to scientists and how are they planning to find it?With Jim Al-Khalili, Senior Lecturer in Physics at the University of Surrey; David Wark, Pro

Melvyn Bragg and guests discusses Zoroastrianism. "Now have I seen him with my own eyes, knowing him in truth to be the wise Lord of the good mind and of good deeds and words." Thus spake the real Zarathustra, the prophet and founder of the ancient and modern religion of Zoroastrianism. It has claims to be the world's first monotheistic creed and perhaps as long ago as 1200 BC Zarathustra also said, "I point out the way, it is the truth, it is for all living". Truth is a central tenet of the religion which holds that people must above all do good things, hear good things and see good things.How was the religion established in Ancient Persia, what is its body of beliefs and how have they been developed and disseminated?With Vesta Sarkhosh Curtis, Curator of Ancient Iranian Coins in the Department of Coins and Medals at the British Museum; Farrokh Vajifdar, Fellow of the Royal Asiatic Society; Alan Williams, Senior Lecturer in Comparative Religion at the University of Manchester.

Melvyn Bragg and guests discuss the dawn of the age of electricity. In Gulliver's Travels, published in 1726, Jonathan Swift satirised natural philosophers as trying to extract sunbeams from cucumbers. Perhaps he would have been surprised, or even horrified, by the sheer force of what these seemingly obscure experimentalists were about to unleash on society. Electricity soon reached into all areas of 18th century life, as Royal Society Fellows vied with showmen and charlatans to reveal its wonders to the world. It was, claimed one commentator, 'an entertainment for Angels rather than for Men'. Electricity also posed deep questions about the nature of life. For some it was the divine spark that animated all things, for others it represented a dangerous materialism that reduced humans to mere machines.But how did electricity develop in the 18th and 19th centuries? Why was it so politically contentious and how was it understood during the age in which it changed the world forever?With Simon Schaffer, Professor i

Melvyn Bragg and guests discuss witchcraft in Reformation Europe. In 1486 a book was published in Latin, it was called Maleus Mallificarum and it very soon outsold every publication in Europe bar the Bible. It was written by Heinrich Kramer, a Dominican Priest and a witchfinder. "Magicians, who are commonly called witches" he wrote, "are thus termed on account of the magnitude of their evil deeds. These are they who by the permission of God disturb the elements, who drive to distraction the minds of men, such as have lost their trust in God, and by the terrible power of their evil spells, without any actual draught or poison, kill human beings.""Thou shalt not suffer a witch to live" says Exodus, and in the period of the Reformation and after, over a hundred thousand men and women in Europe met their deaths after being convicted of witchcraft.Why did practices that had been tolerated for centuries suddenly become such a threat? What brought the prosecutions of witchcraft to an end, and was there anything ever

Melvyn Bragg and guests discusses rhetoric. Gorgias, the great sophist philosopher and master of rhetoric said, "Speech is a powerful lord that with the smallest and most invisible body accomplished most godlike works. It can banish fear and remove grief, and instil pleasure and enhance pity. Divine sweetness transmitted through words is inductive of pleasure and reductive of pain". But for Plato it was a vice, and those like Gorgias who taught rhetoric were teaching the skills of lying in return for money and were a great danger. He warned "this device - be it which it may, art or mere artless empirical knack - must not, if we can help it, strike root in our society".But strike root it did, and there is a rich tradition of philosophers and theologians who have attempted to make sense of it.How did the art of rhetoric develop? What part has it played in philosophy and literature? And does it still deserve the health warning applied so unambiguously by Plato?With Angie Hobbs, Lecturer in Philosophy at the Univ

Melvyn Bragg and guests discuss the Han Synthesis philosophies of China. In The Analects the Chinese sage Confucius says of statecraft: "He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn to it".Confucianism had been all but outlawed under the Chin Emperor, but in 206 BC the Han dynasty came to power and held sway for over 400 years. They brought Confucian thought to the heart of government, his favourite books became set texts for the world's first civil service exam and in a grand intellectual project 'The Great Tao' was combined with 'The Five Phases' and with the Yin and the Yang.Who were the Han? How did they bring these strands of thought together into the great founding moment of Chinese culture? And what drove them to their extraordinary intellectual task?With Christopher Cullen, Director of the Needham Research Institute; Carol Michaelson, Assistant Keeper of Chinese Art in the Department of Asia at the British Muse

Melvyn Bragg and guests discuss Jean-Paul Sartre, the French novelist, playwright, and philosopher who became the king of intellectual Paris and a focus of post war politics and morals. Sartre's own life was coloured by jazz, affairs, Simone de Beauvoir and the intellectual camaraderie of Left Bank cafes. He maintained an extraordinary output of plays, novels, biographies, and philosophical treatises as well as membership of the communist party and a role in many political controversies. He produced some wonderful statements: "my heart is on the left, like everyone else's", and "a human person is what he is not, not what he is", and, most famously "we are condemned to be free". Melvyn Bragg and guests discuss how Sartre's novels and plays express his ideas and what light Sartre's life brings to bear on his philosophy and his philosphy on his life. With Jonathan Rée, philosopher and historia; Benedict O'Donohoe, Principal Lecturer in French at the University of the West of England and Secretary of the UK Soci

Melvyn Bragg and guests discuss the idea of Politeness. A new idea that stalked the land at the start of the eighteenth century in Britain, Politeness soon acquired a philosophy, a literature and even a society devoted to its thrall. It may seem to represent the very opposite now, but at that time, when Queen Anne was on the throne and The Spectator was in the coffee houses, politeness was part of a radical social revolution.How did the idea of politeness challenge the accepted norms of behaviour? How did a notion of how to behave affect the great wealth of eighteenth century culture? With Amanda Vickery, Reader in History at Royal Holloway, University of London; David Wootton, Professor of History at the University of York; John Mullan, Senior Lecturer in English at University College London.

Melvyn Bragg and guests discuss the emergence of the world’s first organic matter nearly four billion years ago. Scientists have named 1.5 million species of living organism on the land, in the skies and in the oceans of planet Earth and a new one is classified every day.  Estimates of how many species remain to be discovered vary wildly, but science accepts one categorical point – all living matter on our planet, from the nematode to the elephant, from the bacterium to the blue whale, is derived from a single common ancestor. What was that ancestor?  Did it really emerge from a ‘primordial soup’? And what, in the explanation of evolutionary science, provided the catalyst to start turning the cycle of life?With Richard Dawkins, Charles Simonyi Professor of the Public Understanding of Science at Oxford University; Richard Corfield, Visiting Senior Lecturer at the Centre for Earth, Planetary, Space and Astronomical Research at the Open University; Linda Partridge, Biology and Biotechnology Research Council Prof

Melvyn Bragg and guests discuss the Battle of Agincourt."Owre kynge went forth to Normandy, With grace and myyt of chivalry; The God for hym wrouyt marvelously, Wherefore Englonde may calle, and cry Deo gratias: Deo gratias redde pro victoria." The great victory was Agincourt as described in the Agincourt Carol, when the 'happy few' of the English army of King Henry V vanquished the French forces on St Crispin's Day 1415. It is a battle that has resounded through the centuries and has been used by so many to mean so much. But how important was the battle in the strategic struggles of the time? What were the pressures at home that drove Henry's march through France? And what is the cultural legacy of Agincourt? With Anne Curry, Professor of Medieval History at Southampton University; Michael Jones, medieval historian and writer; John Watts, Fellow and Tutor in Modern History at Corpus Christie College, Oxford.
