The open society is the successful society

"The most secure and prosperous societies did not hide from the world. They were confident enough to remain open to trade and ideas, allowing the new to challenge the known. Progress emerges when people experiment, borrow, and combine ideas in ways no planner could ever foresee; decline happens when fear overcomes curiosity."

~ Johan Norberg from his article 'From Athens to the Abbasids to today’s Anglosphere, creativity and commerce drive greatness.' in which he explores the central lessons of history’s real golden ages in his new book, Peak Human: What We Can Learn from the Rise and Fall of Golden Ages.
