Melvyn Bragg and guests discuss existentialism. Imagine being back inside the bustling cafes on the Left Bank of Paris in the 1930s, cigarette smoke, strong coffee and the buzz of continental voices philosophising about human responsibility and freedom. This kind of talk gave utterance to Existentialism. A twentieth century philosophy of everyday life concerned with the individual, and his or her place within the world. In novels, plays and philosophy, Existentialists try to work out the nature of our existence. As Roquentin says in Sartre’s novel ‘Nausea’, “To exist is simply to be there; what exists appears, lets itself be encountered, but you can never deduce it”.But where did these ideas come from? What do they really mean? And how have they impacted on our lives? With Dr A. C. Grayling, Reader in Philosophy at Birkbeck College, University of London; Christina Howells, Professor of French at the University of Oxford, fellow of Wadham College; Simon Critchley, Professor of Philosophy at the University of Essex and author of A Companion to Continental Philosophy.

Melvyn Bragg and guests discuss the concept of evil. When Nietzsche killed off God he had it in for evil as well: In Beyond Good and Evil, he constructed an argument against what he called the “herd morality” of Christianity, and he complained "everything that elevates an individual above the herd and intimidates the neighbour is henceforth called evil." Nietzsche claimed that it was a dangerous idea that distorted human nature, ‘evil’ was invented by the church and was a completely alien concept to the noble philosophers of the ancient world. Was he right, did Christianity really invent the idea of evil? And has the idea meant anything more than excessively bad? With Jones Erwin, Lecturer in Philosophy at the University of Limerick; Stephen Mulhall, Tutor in Philosophy at New College, Oxford University; Margaret Atkins, Lecturer in Theology at Trinity and All Saints College, University of Leeds.

Explore the origins of love according to Plato's Symposium and how the concept has evolved in Western society. Delve into Socrates' views on love as a ladder of ascent to the universal. Examine Plato's definition of philia and the promiscuous use of words to describe love. Critique Freud's theory on the origins of love. Delve into Lawrence's unique perspective and the complexity of relationships.

Discussing the origins and evolution of Humanism from Cicero's teachings to Renaissance ideals. Examining the influence of Humanism on Roman education, Christianity, German culture, and the modern era. Exploring criticisms of Humanism such as elitism, sexism, and its tie to Nazism.

Melvyn Bragg and guests discuss the history of Nihilism. The nineteenth-century philosopher, Friedrich Nietzsche, wrote, “There can be no doubt that morality will gradually perish: this is the great spectacle in a hundred acts reserved for the next two centuries in Europe”. And, with chilling predictions like these, ‘Nihilism’ was born. The hard view that morals are pointless, loyalty is a weakness and ‘truths’ are illusory, has excited, confused and appalled western thinkers ever since. But what happened to Nietzsche’s revolutionary ideas about truth, morality and a life without meaning? Existentialism can claim lineage to Nietzsche, as can Post Modernism, but then so can Nazism. With so many interpretations, and claims of ownership from the left and the right, has anything positive come out of the great philosopher of ‘nothing’?With Rob Hopkins, Senior Lecturer in Philosophy, University of Birmingham; Professor Raymond Tallis, Doctor and Philosopher; Professor Catherine Belsey, University of Cardiff.

Exploring the historical quest for simple governing laws in physics, from ancient philosophers to modern string theory. Debate on the universality of physical laws and the application of laws in different systems. Unpredictable nature of sand piles and critical states. Quest for a theory of everything and mathematical patterns in human history.

Melvyn Bragg and guests discuss economic rights. Is democracy the truest conduit of capitalism, or do the forces that make us rich run counter to the democratic institutions that safeguard our rights? The economist Milton Friedman once said, “If freedom weren’t so economically efficient it wouldn’t stand a chance”. If that was ever true, is it still the case as we enter the era of the globalised economy? What is the relationship between democracy and capitalism? Is it possible for a country to get rich and stay rich without a liberal constitution and what is the prospect of the ever looming spectre of ‘globalised capital’ infringing human rights?With Professor Amartya Sen, Master of Trinity College, Cambridge and winner of the 1998 Nobel Prize in Economic Science; Will Hutton, former Editor of The Observer, Director of The Industrial Society and author of The State We’re In.

Melvyn Bragg and guests discuss the problems of consciousness, one of the greatest mysteries facing science and philosophy today. The frustrations, the stubborn facts and the curiosities of today’s thinkers, philosophers, physicists and psychologists, demonstrate the elusiveness, and the utter impenetrability of consciousness. Can we explain our perception of colour, smell or what it is like to be in love in purely physical terms? Can memory, conviction and reason be explained primarily in terms of neural firing sequences in the brain? Three centuries ago Descartes famously believed that the problem was best solved by being ignored. Was he right? Could it be that the human mind is just not built to understand its own basis?With Ted Honderich, philosopher and former Grote Professor of the Philosophy of Mind and Logic, University College, London; Sir Roger Penrose eminent physicist, mathematician and author of The Large, The Small, and the Human Mind.

Melvyn Bragg and guests discuss progress. As man has grown in years and knowledge, has he also progressed in terms of happiness and a true understanding of the human condition? It was the Enlightenment which gave birth to the idea of the possibility of progress. The biblical account of time which had held sway until the eighteenth century was replaced by a conceit which put Man, not God, at the centre of the story of progress. But do we still believe in that story? Have we reached the end of history and the culmination of man’s evolution? Was the Argentinean writer Jorge Louis Borges right when he said “We have stopped believing in progress. What progress that is!”. Can our moral progress keep up with our material progress, be sober in a technologically inebriated world, be in any way more than a fig leaf covering the untameable old Adam whose tragedy - more Greek than Christian - has made and marred this century? Is there such a thing at all as moral progress, or have Darwin and Freud between them cut it out of the conceit of homo sapiens? With Anthony O’Hear, Professor of Philosophy, University of Bradford; Adam Phillips, psychoanalyst and author of Darwin’s Worms.

Exploring the concept of the individual in the Renaissance and its similarities to Hamlet, the development of the individual over time, the impact of societal pressures and power dynamics, the relationship between the individual and society, and the influence of postmodern individualism in metropolitan circles.
