From Stone Age hunter-gatherers to contemporary Chinese-American relations, Open explores how across time and cultures, we have struggled with a constant tension between our yearning for co-operation and our profound need for belonging. Providing a bold new framework for understanding human history, bestselling author and thinker Johan Norberg examines why we're often uncomfortable with openness - but also why it is essential for progress. Part sweeping history and part polemic, this urgent book makes a compelling case for why an open world with an open economy is worth fighting for more than ever.
