Fidel Castro's most original contribution to revolutionary and radical thought has been his development of an explicit ethical position on one of the most controversial issues of our time: violence. This book explores the evolution of Castro's political thinking -- and in particular how he philosophically reconciles violence, political power and morality. This book makes a timely intervention into the question of Castro's historical role and contribution. The author argues that Castro's doctrine of armed struggle is the logical development of his idea of the ethical liberation fighter. At its core is an unremitting emphasis on the ethical use of violence.
