The author of the multi-award-winning The Invention of Nature introduces her magical collaboration with the artist Lillian Melcher.

With encounters with indigenous peoples, missionaries, colonists and jaguars, and incorporating Humboldt’s own sketches, drawings and manuscripts, this is a thrilling adventure story of history’s most daring scientist. Chaired by Oliver Balch.

The historian selects letters that have changed the course of global events or expressed a timeless idea – whether passion, rage or humour – from ancient times to the 21st century.

His correspondents range from Elizabeth I and Catherine the Great to Mandela, Stalin and Picasso, from Fanny Burney and Emily Pankhurst to Ada Lovelace and Rosa Parks, Frida Kahlo, Leonard Cohen, Lincoln, Trump and Suleiman the Magnificent.

Susskind confronts one of the most important questions of our time: how will digital technology transform politics and society? The great political debate of the last century was about how much of our collective life should be determined by the state and what should be left to the market and civil society. In the future, the question will be how far our lives should be directed and controlled by powerful digital systems - and on what terms? Those who control these technologies - usually big tech firms and the state - will increasingly control us. Their algorithms will resolve vital questions of social justice, allocating social goods and sorting us into hierarchies of status and esteem. They will decide the future of democracy, causing it to flourish or decay.
