Street philosophy with award-winning historian and broadcaster Bettany Hughes. She begins each programme with the first, extant evidence of a single word-idea in Ancient Greek culture and travels both forwards and backwards in time, investigating how these ideas have been moulded by history, and how they've shaped us. A history of ideas described as “a double espresso shot of philosophy, history, science and the arts.”
