In Our Time: Philosophy Folgen

Melvyn Bragg and guests Raymond Geuss, Esther Leslie and Jonathan Rée discuss the Frankfurt School.This group of influential left-wing German thinkers set out, in the wake of Germany's defeat in the First World War, to investigate why their country had not had a revolution, despite the apparently revolutionary conditions that spread through Germany in the wake of the 1918 Armistice. To find out why the German workers had not flocked to the Red Flag, Theodor Adorno, Max Horkheimer, Walter Benjamin and others came together around an Institute set up at Frankfurt University and began to focus their critical attention not on the economy, but on culture, asking how it affected people's political outlook and activities. But then, with the rise of the Nazis, they found themselves fleeing to 1940s California. There, their disenchantment with American popular culture combined with their experiences of the turmoil of the interwar years to produce their distinctive, pessimistic worldview. With the defeat of Nazism, they returned to Germany to try to make sense of the route their native country had taken into darkness. In the 1960s, the Frankfurt School's argument - that most of culture helps to keep its audience compliant with capitalism - had an explosive impact. Arguably, it remains influential today.Raymond Geuss is a professor in the Faculty of Philosophy at the University of Cambridge; Esther Leslie is Professor in Political Aesthetics at Birkbeck College, University of London; Jonathan Rée is a freelance historian and philosopher, currently Visiting Professor at Roehampton University and at the Royal College of Art.

Melvyn Bragg and guests John Mullan, Karen O'Brien and Barbara Taylor discuss the life and ideas of the pioneering British Enlightenment thinker Mary Wollstonecraft.Mary Wollstonecraft was born in 1759 into a middle-class family whose status steadily sank as her inept, brutal, drunken father frittered away the family fortune. She did what she could to protect her mother from his aggression; meanwhile, her brother was slated to inherit much of the remaining fortune, while she was to receive nothing.From this unpromising but radicalising start, Wollstonecraft's career took a dizzying trajectory through a bleak period as a governess to becoming a writer, launching a polemical broadside against the political star of the day, witnessing the bloodshed of the French Revolution up close, rescuing her lover's stolen ship in Scandanavia, then marrying one of the leading philosophers of the day, William Godwin, and with him having a daughter who - though she never lived to see her grow up - would go on to write Frankenstein.But most importantly, in 1792, she published her great work, A Vindication of the Rights of Woman, which marks her out as one of the great thinkers of the British Enlightenment, with a much stronger, more lasting influence than Godwin. The Vindication was an attempt to apply the Enlightenment logic of rights and reason to the lives of women. Yet it was not a manifesto for the extension of the vote or the reform of divorce law, but a work of political philosophy. And surprisingly, as recent scholarship has highlighted, it was infused with Rational Dissenting Christianity, which Wollstonecraft had absorbed during her time as a struggling teacher and writer in north London.John Mullan is Professor of English at University College, London; Karen O'Brien is Professor of English at the University of Warwick; Barbara Taylor is Professor of Modern History in the School of Humanities and Social Sciences at the University of East London.

Melvyn Bragg and guests Serafina Cuomo, John O'Connor and Ian Stewart discuss the ideas and influence of the Greek mathematician Pythagoras and his followers, the Pythagoreans.The Ancient Greek mathematician Pythagoras is probably best known for the theorem concerning right-angled triangles that bears his name. However, it is not certain that he actually developed this idea; indeed, some scholars have questioned not only his true intellectual achievements, but whether he ever existed. We do know that a group of people who said they were followers of his - the Pythagoreans - emerged around the fifth century BC. Melvyn Bragg and his guests discuss what we do and don't know about this legendary figure and his followers, and explore the ideas associated with them. Some Pythagoreans, such as Philolaus and Archytas, were major mathematical figures in their own right. The central Pythagorean idea was that number had the capacity to explain the truths of the world. This was as much a mystical belief as a mathematical one, encompassing numerological notions about the 'character' of specific numbers. Moreover, the Pythagoreans lived in accordance with a bizarre code which dictated everything from what they could eat to how they should wash. Nonetheless, Pythagorean ideas, centred on their theory of number, have had a profound impact on Western science and philosophy, from Plato through astronomers like Copernicus to the present day.Serafina Cuomo is Reader in Roman History at Birkbeck College, University of London; John O'Connor is Senior Lecturer in Mathematics at the University of Saint Andrews; Ian Stewart is Emeritus Professor of Mathematics at the University of Warwick.
