Book excerpt: If you think world peace is a naive concept, Paul K. Chappell’s very existence will give you pause. It’s not enough to say that Chappell – a West Point graduate and Iraq War veteran – is a soldier turned peace leader. Experiencing a traumatic upbringing and growing up mixed race in Alabama, he’s a young man forged by violence, rage, and racism into a living weapon for peace. By unlocking the mysteries of human nature, he shows how the muscles of hope, empathy, appreciation, conscience, reason, discipline, and curiosity give us the power to end the wars between countries, our ongoing war with nature, and the war in our hearts.
