In Our Time: Philosophy

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 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 his guests discuss the philosophy of solitude. The state of being alone can arise for many different reasons: imprisonment, exile or personal choice. It can be prompted by religious belief, personal necessity or a philosophical need for solitary contemplation. Many thinkers have dealt with the subject, from Plato and Aristotle to Hannah Arendt. It's a philosophical tradition that takes in medieval religious mystics, the work of Montaigne and Adam Smith, and the great American poets of solitude Thoreau and Emerson.With:Melissa Lane Professor of Politics at Princeton UniversitySimon Blackburn Professor of Philosophy at the New College of the Humanities and Fellow of Trinity College, CambridgeJohn Haldane Professor of Philosophy at the University of St AndrewsProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Max Weber's book the Protestant Ethic and the Spirit of Capitalism. Published in 1905, Weber's essay proposed that Protestantism had been a significant factor in the emergence of capitalism, making an explicit connection between religious ideas and economic systems. Weber suggested that Calvinism, with its emphasis on personal asceticism and the merits of hard work, had created an ethic which had enabled the success of capitalism in Protestant countries. Weber's essay has come in for some criticism since he published the work, but is still seen as one of the seminal texts of twentieth-century sociology.With:Peter Ghosh Fellow in History at St Anne's College, OxfordSam Whimster Honorary Professor in Sociology at the University of New South WalesLinda Woodhead Professor of Sociology of Religion at Lancaster University.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the work of George Berkeley, an Anglican bishop who was one of the most important philosophers of the eighteenth century. Bishop Berkeley believed that objects only truly exist in the mind of somebody who perceives them - an idea he called immaterialism. His interests and writing ranged widely, from the science of optics to religion and the medicinal benefits of tar water. His work on the nature of perception was a spur to many later thinkers, including David Hume and Immanuel Kant. The clarity of Berkeley's writing, and his ability to pose a profound problem in an easily understood form, has made him one of the most admired early modern thinkers.With:Peter Millican Gilbert Ryle Fellow and Professor of Philosophy at Hertford College, OxfordTom Stoneham Professor of Philosophy at the University of YorkMichela Massimi Senior Lecturer in Philosophy of Science at the University of Edinburgh.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss Plato's Symposium, one of the Greek philosopher's most celebrated works. Written in the 4th century BC, it is a dialogue set at a dinner party attended by a number of prominent ancient Athenians, including the philosopher Socrates and the playwright Aristophanes. Each of the guests speaks of Eros, or erotic love. This fictional discussion of the nature of love, how and why it arises and what it means to be in love, has had a significant influence on later thinkers, and is the origin of the modern notion of Platonic love.With:Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldRichard Hunter Regius Professor of Greek at the University of CambridgeFrisbee Sheffield Director of Studies in Philosophy at Christ's College, University of Cambridge.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss Ordinary Language Philosophy, a school of thought which emerged in Oxford in the years following World War II. With its roots in the work of Ludwig Wittgenstein, Ordinary Language Philosophy is concerned with the meanings of words as used in everyday speech. Its adherents believed that many philosophical problems were created by the misuse of words, and that if such 'ordinary language' were correctly analysed, such problems would disappear. Philosophers associated with the school include some of the most distinguished British thinkers of the twentieth century, such as Gilbert Ryle and JL Austin.With:Stephen Mulhall Professor of Philosophy at New College, OxfordRay Monk Professor of Philosophy at the University of SouthamptonJulia Tanney Reader in Philosophy of Mind at the University of KentProducer: Thomas Morris.

Michela Massimi, a Senior Lecturer in the Philosophy of Science, sheds light on Pascal's groundbreaking work in probability theory and geometry. Michael Moriarty, a Drapers Professor of French, discusses Pascal's family background and deep religious convictions. David Wootton, an Anniversary Professor of History, provides context on Pascal's innovative experiments in vacuums and his philosophical insights. Together, they explore the intricate balance between science, faith, and moral thought that defines Pascal’s enduring legacy.

Angie Hobbs, David Sedley and James Warren join Melvyn Bragg to discuss Epicureanism, the system of philosophy based on the teachings of Epicurus and founded in Athens in the fourth century BC. Epicurus outlined a comprehensive philosophical system based on the idea that everything in the Universe is constructed from two phenomena: atoms and void. At the centre of his philosophy is the idea that the goal of human life is pleasure, by which he meant not luxury but the avoidance of pain. His followers were suspicious of marriage and politics but placed great emphasis on friendship. Epicureanism became influential in the Roman world, particularly through Lucretius's great poem De Rerum Natura, which was rediscovered and widely admired in the Renaissance.With:Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldDavid Sedley Laurence Professor of Ancient Philosophy at the University of CambridgeJames Warren Reader in Ancient Philosophy at the University of CambridgeProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the influential British philosopher Bertrand Russell. Born in 1872 into an aristocratic family, Russell is widely regarded as one of the founders of Analytic philosophy, which is today the dominant philosophical tradition in the English-speaking world. In his important book The Principles of Mathematics, he sought to reduce mathematics to logic. Its revolutionary ideas include Russell's Paradox, a problem which inspired Ludwig Wittgenstein to pursue philosophy. Russell's most significant and famous idea, the theory of descriptions, had profound consequences for the discipline.In addition to his academic work, Russell played an active role in many social and political campaigns. He supported women's suffrage, was imprisoned for his pacifism during World War I and was a founder of the Campaign for Nuclear Disarmament. He wrote a number of books aimed at the general public, including The History of Western Philosophy which became enormously popular, and in 1950 he was awarded the Nobel Prize in Literature. Russell's many appearances on the BBC also helped to promote the public understanding of ideas.With: AC Grayling Master of the New College of the Humanities and a Supernumerary Fellow of St Anne's College, OxfordMike Beaney Professor of Philosophy at the University of York Hilary Greaves Lecturer in Philosophy and Fellow of Somerville College, Oxford Producer: Victoria Brignell.
