Idiosyncratic filmmaker, novelist and architecture critic Jonathan Meades in discussion with fellow novelist and child psychologist Charles Fenryhough. Meades is publishing Museum Without Walls, the product of thirty years writing and thinking about places: their ingredients, how and why they were made, their capacity to illumine the societies that inhabit them and the ideas they foment. Charles Fernyhough's new book, Pieces of Light, examines the neuroscientific basis of memory and how it makes us the people we are. Expect an intellectually no-holds-barred exploration of how we invent the outside world and it invents us. Chaired by John Mitchinson
