John Keegan, widely considered the greatest military historian of our time and the author of acclaimed volumes on ancient and modern warfare--including, most recently, The First World War," a national bestseller--distills what he knows about the why's and how's of armed conflict into a series of brilliantly concise essays. Is war a natural condition of humankind? What are the origins of war? Is the modern state dependent on warfare? How does war affect the individual, combatant or noncombatant? Can there be an end to war? Keegan addresses these questions with a breathtaking knowledge of history and the many other disciplines that have attempted to explain the phenomenon. The themes Keegan concentrates on in this short volume are essential to our understanding of why war remains the single greatest affliction of humanity in the twenty-first century, surpassing famine and disease, its traditional companions. 邦題　『戦争と人間の歴史』　（刀水書房 ） 8月15日読売新聞・朝刊「本のソムリエ 」に掲載
