In this dialogue with one of the most interesting minds of our time, the Hebrew University historian and best-selling author (Sapiens, Homo Deus), Dr. Yuval Noah Harari, he and Dr. Shermer discuss the central ideas of his new book, 21 Lessons for the 21st Century, an exploration of: history, work, liberty, equality, community, civilization, nationalism, religion, immigration, terrorism, war, humility, God, secularism, ignorance, justice, post-truth, science fiction, education, meaning, and meditation. Dr. Harari and Dr. Shermer cover as many of these topics as reasonable in this wide-ranging conversation, focusing especially on nationalism, tribalism, God and religion, free will and determinism, AI algorithms and human volition, the future of liberal democracy, colonizing Mars, and much more. Dr. Yuval Noah Harari has a Ph.D. in history from the University of Oxford, and now lectures at the Hebrew University of Jerusalem, specializing in world history. His two books, Sapiens: A Brief History of Humankind and Homo Deus: A Brief History of Tomorrow, have become global best­sellers, with more than twelve million copies sold and translations in more than forty-five languages.
