Hay Festival Classics relaunches a series of unforgettable events from different Hay Festivals, featuring some of the most outstanding figures from the world of literature and ideas. With a fresh viewpoint and subtitles in Spanish, we present conversations that will never lose their power. The Israeli historian and thinker, Yuval Noah Harari, has travelled the world talking about his remarkable books, which include Sapiens, Homo Deus and 21 Lessons for the 21st Century. In conversation with Anita Anand at the 2015 Hay Festival Wales, Harari talks about Sapiens, a book that takes in the whole of human history, from the experiences of the first humans to walk the earth to the advances brought by the cognitive, agricultural and scientific revolutions. How did we start to believe in gods, nations and human rights? How did we come to trust money, books and laws? How will the world be in the centuries to come? Drawing on ideas and evidence from biology, anthropology, palaeontology and economics, the author explores how our human societies and the wider world around them were created or altered by the hand of Homo sapiens.
