Melvyn Bragg and guests discuss the insight into our relationship with the world that Immanuel Kant (1724-1804) shared in his book The Critique of Pure Reason in 1781. It was as revolutionary, in his view, as when the Polish astronomer Copernicus realised that Earth revolves around the Sun rather than the Sun around Earth. Kant's was an insight into how we understand the world around us, arguing that we can never know the world as it is, but only through the structures of our minds which shape that understanding. This idea, that the world depends on us even though we do not create it, has been one of Kant’s greatest contributions to philosophy and influences debates to this day.

Melvyn Bragg and guests discuss the author and philosopher Iris Murdoch (1919 - 1999). In her lifetime she was most celebrated for her novels such as The Bell and The Black Prince, but these are now sharing the spotlight with her philosophy. Responding to the horrors of the Second World War, she argued that morality was not subjective or a matter of taste, as many of her contemporaries held, but was objective, and good was a fact we could recognize. To tell good from bad, though, we would need to see the world as it really is, not as we want to see it, and her novels are full of characters who are not yet enlightened enough to do that.WithAnil Gomes Fellow and Tutor in Philosophy at Trinity College, University of OxfordAnne Rowe Visiting Professor at the University of Chichester and Emeritus Research Fellow with the Iris Murdoch Archive Project at Kingston UniversityAndMiles Leeson Director of the Iris Murdoch Research Centre and Reader in English Literature at the University of ChichesterProducer: Simon Tillotson

In this discussion, Anil Gomes, Sophie Grace Chappell, and Rachael Wiseman delve into the life and impact of Philippa Foot, a pivotal 20th-century philosopher. They explore Foot's challenge to the subjective moral landscape of her time, advocating for objective moral truths rooted in virtue ethics. The conversation touches on her influential ideas about the Trolley Problem and ethical distinctions in applied ethics, particularly around euthanasia. Foot's intellectual journey from privilege to profound ethical insight reveals her lasting legacy in moral philosophy.
