Melvyn Bragg and his guests discuss Adam Smith's celebrated economic treatise The Wealth of Nations. Smith was one of Scotland's greatest thinkers, a moral philosopher and pioneer of economic theory whose 1776 masterpiece has come to define classical economics. Based on his careful consideration of the transformation wrought on the British economy by the Industrial Revolution, and how it contrasted with marketplaces elsewhere in the world, the book outlined a theory of wealth and how it is accumulated that has arguably had more influence on economic theory than any other.With:Richard Whatmore Professor of Modern History and Director of the Institute of Intellectual History at the University of St AndrewsDonald Winch Emeritus Professor of Intellectual History at the University of SussexHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the photon, one of the most enigmatic objects in the Universe. Generations of scientists have struggled to understand the nature of light. In the late nineteenth century it seemed clear that light was an electromagnetic wave. But the work of physicists including Planck and Einstein shed doubt on this theory. Today scientists accept that light can behave both as a wave and a particle, the latter known as the photon. Understanding light in terms of photons has enabled the development of some of the most important technology of the last fifty years.With:Frank Close Professor Emeritus of Physics at the University of OxfordWendy Flavell Professor of Surface Physics at the University of ManchesterSusan Cartwright Senior Lecturer in Physics and Astronomy at the University of Sheffield.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Indian Emperor Ashoka. Active in the 3rd century BC, Ashoka conquered almost all of the landmass covered by modern-day India, creating the largest empire South Asia had ever known. After his campaign of conquest he converted to Buddhism, and spread the religion throughout his domain. His edicts were inscribed on the sides of an extraordinary collection of stone pillars spread far and wide across his empire, many of which survive today. Our knowledge of ancient India and its chronology, and how this aligns with the history of Europe, is largely dependent on this important set of inscriptions, which were deciphered only in the nineteenth century.With:Jessica Frazier Lecturer in Religious Studies at the University of Kent and a Research Fellow at the Oxford Centre for Hindu StudiesNaomi Appleton Chancellor's Fellow in Religious Studies at the University of EdinburghRichard Gombrich Founder and Academic Director of the Oxford Centre for Buddhist Studies and Emeritus Professor of Sanskrit at the University of OxfordProducer: Thomas Morris.

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.

Melvyn Bragg and guests discuss phenomenology, a style of philosophy developed by the German thinker Edmund Husserl in the first decades of the 20th century. Husserl's initial insights underwent a radical transformation in the work of his student Martin Heidegger, and played a key role in the development of French philosophy at the hands of writers like Emmanuel Levinas, Jean-Paul Sartre, Simone de Beauvoir and Maurice Merleau-Ponty.Phenomenology has been a remarkably adaptable approach to philosophy. It has given its proponents a platform to expose and critique the basic assumptions of past philosophy, and to talk about everything from the foundations of geometry to the difference between fear and anxiety. It has also been instrumental in getting philosophy out of the seminar room and making it relevant to the lives people actually lead.

Melvyn Bragg and guests discuss Pieter Bruegel the Elder's painting of 1559, 'The Fight Between Carnival And Lent'. Created in Antwerp at a time of religious tension between Catholics and Protestants, the painting is rich in detail and seems ripe for interpretation. But Bruegel is notoriously difficult to interpret. His art seems to reject the preoccupations of the Italian Renaissance, drawing instead on techniques associated with the new technology of the 16th century, print. Was Bruegel using his art to comment on the controversies of his day? If so, what comment was he making?

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.
