Some books emerge from a lifetime of hard-won knowledge. Robert D. Kaplan has learned, from a career spent reporting on wars, revolutions, and international politics in Europe, the Middle East, and East Asia, that the essence of geopolitics is tragedy. In The Tragic Mind, he employs the works of ancient Greek dramatists, Shakespeare, German philosophers, and the modern classics to explore the central subjects of international politics: order, disorder, rebellion, ambition, loyalty to family and state, violence, and the mistakes of power.
