In Our Time: Philosophy

Melvyn Bragg and guests dicuss what it means to be oneself, a question explored by philosophers from Aristotle to the present day, including St Augustine, Kierkegaard, Heidegger and Sartre. In Hamlet, Polonius said 'To thine own self be true', but what is the self, and what does it mean to be true to it, and why should you be true? To Polonius, if you are true to yourself, ‘thou canst not be false to any man’ - but with the rise of the individual, authenticity became a goal in itself, regardless of how that affected others. Is authenticity about creating yourself throughout your life, or fulfilling the potential with which you were born, connecting with your inner child, or something else entirely? What are the risks to society if people value authenticity more than morality - that is, if the two are incompatible? The image above is of Sartre, aged 8 months, perhaps still connected to his inner child.

Melvyn Bragg and guests discuss the remarkable achievement of Aristotle (384-322BC) in the realm of biological investigation, for which he has been called the originator of the scientific study of life. Known mainly as a philosopher and the tutor for Alexander the Great, who reportedly sent him animal specimens from his conquests, Aristotle examined a wide range of life forms while by the Sea of Marmara and then on the island of Lesbos. Some ideas, such as the the spontaneous generation of flies, did not survive later scrutiny, yet his influence was extraordinary and his work was unequalled until the early modern period. The image above is of the egg and embryo of a dogfish, one of the animals Aristotle described accurately as he recorded their development.

Melvyn Bragg and guests discuss the philosophy of hope. To the ancient Greeks, hope was closer to self-deception, one of the evils left in Pandora's box or jar, in Hesiod's story. In Christian tradition, hope became one of the theological virtues, the desire for divine union and the expectation of receiving it, an action of the will rather than the intellect. To Kant, 'what may I hope' was one of the three basic questions which human reason asks, while Nietzsche echoed Hesiod, arguing that leaving hope in the box was a deception by the gods, reflecting human inability to face the demands of existence. Yet even those critical of hope, like Camus, conceded that life was nearly impossible without it.

Melvyn Bragg and guests discuss Bernard Mandeville (1670-1733) and his critique of the economy as he found it in London, where private vices were condemned without acknowledging their public benefit. In his poem The Grumbling Hive (1705), he presented an allegory in which the economy collapsed once knavish bees turned honest. When republished with a commentary, The Fable of the Bees was seen as a scandalous attack on Christian values and Mandeville was recommended for prosecution for his tendency to corrupt all morals. He kept writing, and his ideas went on to influence David Hume and Adam Smith, as well as Keynes and Hayek. With David Wootton Anniversary Professor of History at the University of York Helen Paul Lecturer in Economics and Economic History at the University of Southampton And John Callanan Senior Lecturer in Philosophy at King’s College London Producer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas of Charles-Louis de Secondat, Baron de La Brède et de Montesquieu (1689-1755) whose works on liberty, monarchism, despotism, republicanism and the separation of powers were devoured by intellectuals across Europe and New England in the eighteenth century, transforming political philosophy and influencing the American Constitution. He argued that an individual's liberty needed protection from the arm of power, checking that by another power; where judicial, executive and legislative power were concentrated in the hands of one figure, there could be no personal liberty. With Richard Bourke Professor in the History of Political Thought at Queen Mary, University of London Rachel Hammersley Senior Lecturer in Intellectual History at Newcastle University And Richard Whatmore Professor of Modern History at the University of St Andrews and Director of the St Andrews Institute of Intellectual History Producer: Simon Tillotson.
