In Our Time

Melvyn Bragg and guests discuss Homer's Iliad, its depiction of the Trojan War, the nature of heroic culture, and how the poem has shaped Western conceptions of glory, honor, and the tragedy of war for nearly three millennia.

The 1215 agreement between King John and his rebellious barons. The panel examines how a failed peace treaty between medieval elites became the foundation of constitutional liberty — a transformation its authors never intended.

The ancient trade routes connecting China to the Mediterranean. The panel examines how silk, spices, religions, technologies, and diseases traveled the Silk Road, creating the first intercontinental network of exchange.

Bragg and mathematicians discuss Fermat's Last Theorem, the 358-year quest to prove it, and Andrew Wiles' dramatic proof in 1995. The episode explores how a margin note became the most famous unsolved problem in mathematics.

Confucius and the philosophical tradition that shaped East Asian civilization for 2,500 years. The panel examines the Analects, the five relationships, the concept of ren (benevolence), and li (ritual propriety).

Bragg and historians discuss the Black Death of 1347-1351, which killed 30-60% of Europe's population. The panel examines the social, economic, and psychological consequences of the worst pandemic in recorded history.

The golden age of Islamic mathematics. The panel examines how scholars in Baghdad, Cairo, and Cordoba preserved Greek mathematics, invented algebra, developed the decimal system, and created the mathematical foundations that Europe later inherited.

The 500th edition of In Our Time tackles one of philosophy's most enduring problems. The panel examines arguments from determinism to libertarian free will to compatibilism, and why the question matters for morality, law, and everyday life.

Plato's most famous dialogue. The panel examines the Republic's arguments about justice, the ideal state, the philosopher-king, the allegory of the cave, and the divided line — and whether Plato was describing a utopia or a totalitarian nightmare.

Darwin's masterwork and the theory of evolution by natural selection. The panel examines the book's argument, its reception, and its status as arguably the most important scientific work ever published.

The physics of gravity from Newton to Einstein. The panel traces how our understanding of the most familiar force in nature evolved from Newton's mathematical description to Einstein's radical reconceptualization as the curvature of spacetime.

Nietzsche's most provocative work. The panel examines his critique of morality, the will to power, master and slave moralities, and the call for a 'revaluation of all values' — asking whether Nietzsche was a dangerous nihilist or a profound psychologist.

The Industrial Revolution — the most important transformation in human history since agriculture. The panel examines why it happened in Britain, why in the 18th century, and how it transformed human civilization more profoundly than any political revolution.

Karl Marx — voted the greatest philosopher in history by In Our Time listeners. The panel examines Marx's ideas about class, capitalism, alienation, and historical materialism, and assesses their relevance two decades after the fall of Soviet communism.

The French Revolution's descent into state-sponsored mass killing. The panel examines how revolutionary idealism became revolutionary violence, and whether the Terror was an aberration or a logical consequence of revolutionary logic.

Bragg and philosophers discuss Stoic philosophy from Zeno through Marcus Aurelius, examining how the Stoic framework of distinguishing between what we can and cannot control became one of the most enduring practical philosophies in Western history.

The hard problem of consciousness. The panel examines why subjective experience exists at all, why physical processes in the brain produce the felt quality of experience, and whether science can ever explain consciousness.

The biology of the cell — the fundamental unit of life. The panel traces the discovery of cells from Hooke through Schwann to modern molecular biology, examining how our understanding of this basic unit has transformed medicine and our concept of life itself.
