Melvyn Bragg and his guests discuss the life and work of the Dutch humanist scholar Desiderius Erasmus. In his lifetime Erasmus was almost universally recognised as the greatest classical scholar of his age, the translator and editor of numerous Latin and Greek texts. But above all he was a religious scholar who published important editions of the Bible which expunged many corruptions to the texts of the Scriptures. He was an outspoken critic of the Church, whose biting satire on its excesses, In Praise of Folly, was famed throughout Europe.When the Reformation began in 1517, however, Erasmus chose to remain a member of the Catholic Church rather than side with Martin Luther and the reformers, and a few years later he engaged in a celebrated debate with Luther on the subject of free will. Through his writings on the Church, on education and the wide gamut of humanist scholarship, Erasmus is remembered today as one of the greatest thinkers of the northern Renaissance.With:Diarmaid MacCullochProfessor of the History of the Church at the University of OxfordEamon DuffyProfessor of the History of Christianity at the University of CambridgeJill KrayeProfessor of the History of Renaissance Philosophy and Librarian at the Warburg Institute, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the evolution of the Scientific Method, the systematic and analytical approach to scientific thought. In 1620 the great philosopher and scientist Francis Bacon published the Novum Organum, a work outlining a new system of thought which he believed should inform all enquiry into the laws of nature. Philosophers before him had given their attention to the reasoning that underlies scientific enquiry; but Bacon's emphasis on observation and experience is often seen today as giving rise to a new phenomenon: the scientific method.The scientific method, and the logical processes on which it is based, became a topic of intense debate in the seventeenth century, and thinkers including Isaac Newton, Thomas Huxley and Karl Popper all made important contributions. Some of the greatest discoveries of the modern age were informed by their work, although even today the term 'scientific method' remains difficult to define.With: Simon SchafferProfessor of the History of Science at the University of CambridgeJohn WorrallProfessor of the Philosophy of Science at the London School of Economics and Political ScienceMichela MassimiSenior Lecturer in the Philosophy of Science at University College London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss 1848, the year that saw Europe engulfed in revolution. Across the continent, from Paris to Palermo, liberals rose against conservative governments. The first stirrings of rebellion came in January, in Sicily; in February the French monarchy fell; and within a few months Germany, Austria, Hungary and Italy had all been overtaken by revolutionary fervour. Only a few countries, notably Britain and Russia, were spared.The rebels were fighting for nationalism, social justice and civil rights, and were prepared to fight in the streets down to the last man. Tens of thousands of people lost their lives; but little of lasting value was achieved, and by the end of the year the liberal revolutions had been soundly beaten.With: Tim BlanningEmeritus Professor of History at the University of CambridgeLucy RiallProfessor of History at Birkbeck, University of LondonMike RapportSenior Lecturer in History at the University of Stirling.Producer: Thomas Morris.

Melvyn Bragg and guests discuss the giant molecules that form the basis of all life. Macromolecules, also known as polymers, are long chains of atoms. They form the proteins that make up our bodies, as well as many of the materials of modern life. Man's ability to mimic the structure of macromolecules has led to the invention of plastics such as nylon, paints and adhesives. Most of our clothes are made of macromolecules, and our food is macromolecular. The medical sciences are making increasingly sophisticated use of macromolecules, from growing replacement skin and bone to their increasing use in drug delivery. One of the most famous macromolecules is DNA, an infinitely more complex polymer than man has ever managed to produce. We've only known about macromolecules for just over a century, so what is the story behind them and how might they change our lives in the future?With:Tony RyanPro-Vice Chancellor for the Faculty of Science at the University of SheffieldAthene DonaldProfessor of Experimental Physics at the University of Cambridge and a Fellow of Robinson CollegeCharlotte WilliamsReader in Polymer Chemistry and Catalysis at Imperial College, London Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss Daniel Defoe's novel Robinson Crusoe. Published in 1719, it was an immediate success and is considered the classic adventure story. There are several incidents that may have inspired the tale, although none of them exactly mirrors Defoe's thrilling yet didactic narrative. The plot is now universally known - the sailor stranded on a desert island who learns to tame the environment and the native population. The character of Friday, Crusoe's trusty companion and servant, has become almost as famous as Crusoe himself and their master-servant relationship forms one of the principal themes in the novel. Robinson Crusoe has been interpreted in myriad ways, from colonial fable to religious instruction manual to capitalist tract; although arguably above all of these, it is perhaps best known today as a children's story.
