In 21 Lessons for the 21st Century, bestselling historian Yuval Noah Harari turns his attention to the present, dissecting the most critical challenges facing humanity today. Unlike Sapiens (which examined our past) and Homo Deus (which imagined our future), this book confronts the here and now—exploring artificial intelligence, big data, climate change, terrorism, nationalism, fake news, and the crisis of truth.

Harari’s 21 thought-provoking essays tackle urgent questions: What does the future of work look like in an age of automation? How do we educate children for a world we can’t predict? Can democracy survive the information age? What role does religion play in the 21st century?

Written with clarity and insight, this 432-page hardcover published by Vintage (2018) is both intellectually rigorous and highly readable. Harari combines history, philosophy, and personal reflection to help readers stay informed, think critically, and build resilience amid rapid change.

Key themes include:

• The impact of AI and automation on employment and society
• The spread of misinformation and post-truth politics
• Nationalism vs. Globalism in an interconnected world
• The search for meaning in an uncertain age
• Education, meditation, and mental resilience

This used hardcover is in excellent condition—perfect for readers seeking big ideas and practical wisdom for navigating the 21st century.
