Melvyn Bragg and guests discuss hell and its representation in literature and the visual arts, through the ages from Ancient Egypt to modern Christianity. Why do certain religions have a Satan figure and others don’t? And why did hell shift from the underworld to here on earth in 20th Century representations?A fiery vault beneath the earth or as Sartre put it, other people - it seems our ideas of hell are inevitably shaped by religious and cultural forces. For Homer and Virgil it’s a place you can visit and return from, often a wiser person for it. With Christianity it’s a one way journey and a just punishment for a sinful, unrepentant life. Writers and painters like Dante and Hieronymus Bosch gave free rein to their imaginations, depicting a complex hierarchical world filled with the writhing bodies of tormented sinners. In the 20th century hell can be found on earth in portrayals of war and the Holocaust but also in the mind, particularly in the works of TS Eliot and Primo Levi. So what is the purpose of hell and why is it found mainly in religions concerned with salvation? Why has hell proved so inspirational for artists through the ages, perhaps more so than heaven? And why do some ideas of hell require a Satan figure while others don't?With Martin Palmer, Director of the International Consultancy on Religion, Education and Culture; Margaret Kean, Tutor and Fellow in English at St Hilda’s College, Oxford; Neil MacGregor, Director of the British Museum.

Melvyn Bragg and guests discuss the contribution Indian mathematicians have made to our understanding of the subject. Mathematics from the Indian subcontinent has provided foundations for much of our modern thinking on the subject. They were thought to be the first to use zero as a number. Our modern numerals have their roots there too. And mathematicians in the area that is now India, Pakistan and Bangladesh were grappling with concepts such as infinity centuries before Europe got to grips with it. There’s even a suggestion that Indian mathematicians discovered Pythagoras’ theorem before Pythagoras. Some of these advances have their basis in early religious texts which describe the geometry necessary for building falcon-shaped altars of precise dimensions. Astronomical calculations used to decide the dates of religious festivals also encouraged these mathematical developments. So how were these advances passed on to the rest of the world? And why was the contribution of mathematicians from this area ignored by Europe for centuries?With George Gheverghese Joseph, Honorary Reader in Mathematics Education at Manchester University; Colva Roney-Dougal, Lecturer in Pure Mathematics at the University of St Andrews; Dennis Almeida, Lecturer in Mathematics Education at Exeter University and the Open University.

Melvyn Bragg and guests discuss Anarchism, tracing its roots to philosophers like Proudhon and its influence on movements like communism and feminism. They explore the concept of anarchy as 'without rulers' and its impact on the Spanish Civil War. The podcast delves into the evolution of anarchist ideas, from the early rejection of a ruling class to the principles of mutual aid and shared possessions. It examines the challenges faced by anarchists in defending their beliefs and the factors that made the 19th and early 20th centuries the high point for anarchism.

Melvyn Bragg and guests discuss the speed of light. Scientists and thinkers have been fascinated with the speed of light for millennia. Aristotle wrongly contended that the speed of light was infinite, but it was the 17th Century before serious attempts were made to measure its actual velocity – we now know that it’s 186,000 miles per second. Then in 1905 Einstein’s Special Theory of Relativity predicted that nothing can travel faster than the speed of light. This then has dramatic effects on the nature of space and time. It’s been thought the speed of light is a constant in Nature, a kind of cosmic speed limit, now the scientists aren’t so sure. With John Barrow, Professor of Mathematical Sciences and Gresham Professor of Astronomy at Cambridge University; Iwan Morus, Senior Lecturer in the History of Science at The University of Wales, Aberystwyth; Jocelyn Bell Burnell, Visiting Professor of Astrophysics at Oxford University.

Melvyn Bragg and guests discuss altruism. The term altruism was coined by the 19th century sociologist Auguste Comte and is derived from the Latin “alteri” or "the others”. It describes an unselfish attention to the needs of others. Comte declared that man had a moral duty to “serve humanity, whose we are entirely.” The idea of altruism is central to the main religions: Jesus declared “you shall love your neighbour as yourself” and Mohammed said “none of you truly believes until he wishes for his brother what he wishes for himself”. Buddhism too advocates “seeking for others the happiness one desires for oneself.”Philosophers throughout time have debated whether such benevolence towards others is rooted in our natural inclinations or is a virtue we must impose on our nature through duty, religious or otherwise. Then in 1859 Darwin’s ideas about competition and natural selection exploded onto the scene. His theories outlined in the Origin of Species painted a world “red in tooth and claw” as every organism struggles for ascendancy.So how does this square with altruism? If both mankind and the natural world are selfishly seeking to promote their own survival and advancement, how can we explain being kind to others, sometimes at our own expense? How have philosophical ideas about altruism responded to evolutionary theory? And paradoxically, is it possible that altruism can, in fact, be selfish?With Miranda Fricker, Senior Lecturer in the School of Philosophy at Birkbeck, University of London; Richard Dawkins, evolutionary biologist and the Charles Simonyi Professor of the Public Understanding of Science at Oxford University; John Dupré, Professor of Philosophy of Science at Exeter University and director of Egenis, the ESRC Centre for Genomics in Society.

Melvyn Bragg and guests discuss the Peasants’ Revolt of 1381. “When Adam delved and Eve span, who was then the Gentleman?" these are the opening words of a rousing sermon, said to be by John Ball, which fires a broadside at the deeply hierarchical nature of fourteenth century England. Ball, along with Wat Tyler, was one of the principal leaders of the Peasants’ Revolt – his sermon ends: "I exhort you to consider that now the time is come, appointed to us by God, in which ye may (if ye will) cast off the yoke of bondage, and recover liberty". The subsequent events of June 1381 represent a pivotal and thrilling moment in England’s history, characterised by murder and mayhem, beheadings and betrayal, a boy-King and his absent uncle, and a general riot of destruction and death. By most interpretations, the course of this sensational story threatened to undermine the very fabric of government as an awareness of deep injustice was awakened in the general populace.But who were the rebels and how close did they really come to upending the status quo? And just how exaggerated are claims that the Peasants’ Revolt laid the foundations of the long-standing English tradition of radical egalitarianism? With Miri Rubin, Professor of Early Modern History at Queen Mary, University of London; Caroline Barron, Professorial Research Fellow at Royal Holloway, University of London; Alastair Dunn, author of The Peasants’ Revolt - England’s Failed Revolution of 1381.
