De Botton reclaimed the self-help genre in 2004 with ‘How Proust Can Change Your Life’ and has since written a stack of non-fiction books that attempt to philosophically unpick complex subjects. But his first book was a novel and now, 23 years later, he has released the sequel: an unromantic novel called ‘The Course of Love’. He joins Georgina Godwin to discuss the complicated world of relationships.
