"Fascinating… compelling… [Harari] has teed up a crucial global conversation about how to take on the problems of the 21st century." (Bill Gates New York Times) "The great thinker of our age." (The Times) "Truly mind-expanding… Ultra-topical… Harari’s big selling point [is] the ambition and breadth of his work, smashing together unexpected ideas into dazzling observations." (Guardian) "Erudite, illuminating, vivid. [Harari’s] lessons suggest new ways of thinking about current problems… a splendid, sobering, stirring call to arms." (Sunday Times) "There is surely no one alive who is better at explaining our world than Yuval Noah Harari - he is the lecturer we all wish we’d had at university. Reading this book, I must have interrupted my partner a hundred times to pass on fascinating things I’d just read. Harari has done it again - 21 Lessons is, simply put, a crucial book." (Adam Kay)
