Melvyn Bragg and his guests discuss the ancient Greek historian Thucydides. In the fifth century BC Thucydides wrote The History of the Peloponnesian War, an account of a conflict in which he had himself taken part. This work is now seen as one of the first great masterpieces of history writing, a book which influenced writers for centuries afterwards. Thucydides was arguably the first historian to make a conscious attempt to be objective, bringing a rational and impartial approach to his scholarship. Today his work is still widely studied at military colleges and in the field of international relations for the insight it brings to bear on complex political situations.With:Paul Cartledge Emeritus Professor of Greek Culture and AG Leventis Senior Research Fellow at Clare College, CambridgeKatherine Harloe Associate Professor in Classics and Intellectual History at the University of ReadingNeville Morley Professor of Ancient History at the University of BristolProducer: Thomas Morris.

Guests discuss phenomenology, a philosophy style by Edmund Husserl, tracing its evolution to Heidegger. Topics include critiquing past philosophy, the foundations of geometry, fear vs. anxiety, and making philosophy relevant to everyday life.

Art historian Melvyn Bragg joins in analyzing Bruegel's painting 'The Fight Between Carnival and Lent', exploring the tension between Catholicism and Protestanism, the influence of the Italian Renaissance, and Bruegel's unique approach to art through printmaking. They delve into the symbolic elements of the painting, societal dynamics of the 16th century, and Bruegel's legacy in Western art.

Melvyn Bragg and his guests discuss the philosophy of truth. Pontius Pilate famously asked: what is truth? In the twentieth century, the nature of truth became a subject of particular interest to philosophers, but they preferred to ask a slightly different question: what does it mean to say of any particular statement that it is true? What is the difference between these two questions, and how useful is the second of them?With:Simon Blackburn Fellow of Trinity College, University of Cambridge, and Professor of Philosophy at the New College of the HumanitiesJennifer Hornsby Professor of Philosophy at Birkbeck, University of LondonCrispin Wright Regius Professor of Logic at the University of Aberdeen, and Professor of Philosophy at New York UniversityProducer: Victoria Brignell and Luke Mulhall.

Melvyn Bragg and guests discuss Behavioural Ecology, the scientific study of animal behaviour.What factors influence where and what an animal chooses to eat? Why do some animals mate for life whilst others are promiscuous? Behavioural ecologists approach questions like these using Darwin's theory of natural selection, along with ideas drawn from game theory and the economics of consumer choice.Scientists had always been interested in why animals behave as they do, but before behavioural ecology this area of zoology never got much beyond a collection of interesting anecdotes. Behavioural ecology gave researchers techniques for constructing rigorous mathematical models of how animals act under different circumstances, and for predicting how they will react if circumstances change. Behavioural ecology emerged as a branch of zoology in the second half of the 20th century and proponents say it revolutionized our understanding of animals in their environments.GUESTSSteve Jones, Emeritus Professor of Genetics at University College LondonRebecca Kilner, Professor of Evolutionary Biology at the University of CambridgeJohn Krebs, Principal of Jesus College at the University of OxfordProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Zen. It's often thought of as a form of Buddhism that emphasises the practice of meditation over any particular set of beliefs. In fact Zen belongs to a particular intellectual tradition within Buddhism that took root in China in the 6th century AD. It spread to Japan in the early Middle Ages, where Zen practitioners set up religious institutions like temples, monasteries and universities that remain important today.GUESTSTim Barrett, Emeritus Professor in the Department of the Study of Religions at SOAS, University of LondonLucia Dolce, Numata Reader in Japanese Buddhism at SOAS, University of LondonEric Greene, Lecturer in East Asian Religions at the University of BristolProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Franz Kafka's novel of power and alienation 'The Trial', in which readers follow the protagonist Joseph K into a bizarre, nightmarish world in which he stands accused of an unknown crime; courts of interrogation convene in obscure tenement buildings; and there seems to be no escape from a crushing, oppressive bureaucracy.Kafka was a German-speaking Jew who lived in the Czech city of Prague, during the turbulent years which followed the First World War. He spent his days working as a lawyer for an insurance company, but by night he wrote stories and novels considered some of the high points of twentieth century literature. His explorations of power and alienation have chimed with existentialists, Marxists, psychoanalysts, postmodernists - and Radio 4 listeners, who suggested this as our topic for listener week on In Our Time.GUESTSElizabeth Boa, Professor Emerita of German at the University of Nottingham Steve Connor, Grace 2 Professor of English at the University of Cambridge Ritchie Robertson, Taylor Professor of the German Language and Literature at the University of OxfordProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Aesop. According to some accounts, Aesop was a strikingly ugly slave who was dumb until granted the power of speech by the goddess Isis. In stories of his life he's often found outwitting his masters using clever wordplay, but he's best known today as the supposed author of a series of fables that are some of the most enduringly popular works of Ancient Greek literature. Some modern scholars question whether he existed at all, but the body of work that has come down to us under his name gives us a rare glimpse of the popular culture of the Ancient World.WITHPavlos Avlamis, Junior Research Fellow in Classics at Trinity College at the University of OxfordSimon Goldhill, Professor of Greek Literature and Culture at the University of CambridgeLucy Grig, Senior Lecturer in Classics at the University of EdinburghProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Isambard Kingdom Brunel, the Victorian engineer responsible for bridges, tunnels and railways still in use today more than 150 years after they were built. Brunel represented the cutting edge of technological innovation in Victorian Britain, and his life gives us a window onto the social changes that accompanied the Industrial Revolution. Yet his work was not always successful, and his innovative approach to engineering projects was often greeted with suspicion from investors. Guests:Julia Elton, former President of the Newcomen Society for the History of Engineering and TechnologyBen Marsden, Senior Lecturer in the School of Divinity, History and Philosophy at the University of AberdeenCrosbie Smith, Professor of the History of Science at the University of KentProducer: Luke Mulhall.

Melvyn Bragg and guests discuss the Egyptian pharaoh Hatshepsut, whose name means 'foremost of noble ladies'. She ruled Egypt from about 1479 - 1458 BC and some scholars argue that she was one of the most successful and influential pharaohs. When she came to the throne, Egypt was still recovering from a period of turbulence known as the Second Intermediate Period a few generations earlier. Hatshepsut reasserted Egyptian power by building up international trade and commissioned buildings considered masterpieces of Egyptian architecture. She also made significant changes to the ideology surrounding the pharaoh and the gods. However, following her death, her name was erased from the records and left out of ancient lists of Egyptian kings.With:Elizabeth Frood Associate Professor of Egyptology at the University of OxfordKate Spence Lecturer in Egyptian Archaeology at the University of CambridgeCampbell Price Curator of Egypt and Sudan at The Manchester MuseumProducer: Victoria Brignell.
