OPTIMISTS called the first world war “the war to end all wars”. Philosopher George Santayana demurred. In its aftermath he declared: “Only the dead have seen the end of war”. History has proved him right, of course. What’s more, today virtually nobody believes that humankind will ever transcend the violence and bloodshed of warfare. I know this because for years I have conducted numerous surveys asking people if they think war is inevitable. Whether male or female, liberal or conservative, old or young, most people believe it is. For example, when I asked students at my university “Will humans ever stop fighting wars?” more than 90 per cent answered “No”. Many justified their assertion by adding that war is “part of human nature” or “in our genes”. But is it really?
Such views certainly seem to chime with recent research on the roots of warfare. Just a few decades ago, many scholars believed that prior to civilisation, humans were “noble savages” living in harmony with each other and with nature. Not any more. Ethnographic studies, together with some archaeological evidence, suggest that tribal societies engaged in lethal group conflict, at least occasionally, long before the emergence of states with professional armies (see our timeline of weapons technology). Meanwhile, the discovery that male chimpanzees from one troop sometimes beat to death those from another has encouraged popular perceptions that warfare is part of our biological heritage.
These findings about violence among our ancestors and primate cousins (see “When apes attack”) have perpetuated what anthropologist Robert Sussman from Washington University in St. Louis, Missouri, calls the “5 o’clock news” view of human nature. Just as evening news shows follow the dictum “if it bleeds, it leads”, so many accounts of human behaviour emphasise conflict. However, Sussman believes the popular focus on violence and warfare is disproportionate. “Statistically, it is more common for humans to be cooperative and to attempt to get along than it is for them to be uncooperative and aggressive towards one another,” he says. And he is not alone in this view. A growing number of experts are now arguing that the urge to wage war is not innate, and that humanity is already moving in a direction that could make war a thing of the past.
Among the revisionists are anthropologists Carolyn and Melvin Ember from Yale University, who argue that biology alone cannot explain documented patterns of warfare. They oversee the Human Relations Area Files, a database of information on some 360 cultures, past and present. More than nine-tenths of these societies have engaged in warfare, but some fight constantly, others rarely, and a few have never been observed fighting. “There is variation in the frequency of warfare when you look around the world at any given time,” says Melvin Ember. “That suggests to me that we are not dealing with genes or a biological propensity.”
