In this book, Robert O'Connell examines the role and significance of weapons from the dawn of human history to the present, and the attempts of Western civilization to come to terms with the results of its own inventiveness. It integrates the evolution of human society with the development of weapons and strategy. While primarily historical in his approach, O'Connell also draws upon anthropology, sociology, biology, and literature in his effort to explain certain recurring phenomena of warfare: the human need to dehumanize the enemy, arms races involving weapons which have developed beyond the point of utility, or the ideal of heroism rendered obsolete by deadly new technologies.
