How Can I Know Anything at All?

08/03/15 • 13 min

A history of ideas. Presented by Melvyn Bragg but told in many voices.

Each week Melvyn is joined by four guests with different backgrounds to discuss a really big question. This week he's asking 'How can I know anything at all?'

Helping him answer it are physicist Tara Shears, lawyer Harry Potter, philosopher Clare Carlisle and neuropsychologist Paul Broks.

For the rest of the week Tara, Harry, Clare and Paul will take us further into the history of this idea with programmes of their own. Between them they will examine: David Hume's debunking of miracles; Wittgenstein's attempt to prove that other people have minds; Karl Popper's idea of falsification, which underpins the scientific method; and George Berkeley's approach to a famous philosophical problem - If a tree falls in a forest and no one is around to hear it, does it make a sound?

Producer: Melvin Rickarby.

Writer Lisa Appignanesi on the Love of Children

How should we love our children? Can we build on the feelings we experience when we see them for the first time, raise them by instinct and personal principles or should we consult the childcare gurus of the internet and the bookshelves?

Lisa Appignanesi, the novelist, biographer and author of 'All About Love' suggests that we should turn to the first childcare expert of them all, Jean-Jacques Rousseau. The father of the Romantic movement was one of the first philosophers to consider the importance of the initial bond between mother and child, strongly opposing the fashionable habit of farming newborn babies out to wet nurses.

Rousseau failed to follow his own advice, abandoning his five children to the Paris orphanage, but his writing belatedly raised our children to a status worthy of philosophical debate.

Lisa is joined in her ruminations by psychoanalyst, Adam Phillips, Rousseau expert Christopher Brooke and her own son and grandson.

This is part of a week of progammes asking, 'What is love?'.

Lawyer Harry Potter on Eyewitness Testimony

Barrister Harry Potter asks whether we can believe the evidence of our own eyes. It's a vital question for the justice system today and Harry traces it back to the work of 18th century Philosopher David Hume. Hume, a key figure in the Scottish Enlightenment, wrote about miracles, arguing they were most likely the product of wishful thinking and faulty perception. His arguments are still important for barristers, judges and juries still reliant on eye witness testimony to decide guilt or innocence.

To find out how our eyes deceive us, Harry meets professor Amina Menon, expert in eye witness evidence at Royal Holloway, University of London. And Harry visits professor of philosophy Peter Millican at Oxford University to ask whether Hume's methods can help us overcome our inbuilt biases.
