In Destination Tokyo 1943, the only military-action film he made during the war, Cary Grant plays Captain Cassidy who skippers his torpedo-laden thunderfish, the U.S.S. Copperfin with courage and resourcefulness as it makes its battle-strewn way from San Francisco to the Aleutians and into the enemy’s front yard. Under the trim, taut direction of Delmar Daves in his directorial debut, John Garfield leads a stellar array of costars as boys-next-door gone to war. Makes a perfect naval companion to Howard Hawks’ Air Force 1943.
“It may astonish you readers, as it initially astonished me,” Diamond writes, “to learn that trench warfare, machine guns, napalm, atomic bombs,
artillery, and submarine torpedoes produce time-averaged war-related death tolls so much lower than those from spears, arrows, and clubs.” So how can this be? Because “state warfare is an intermittent exceptional condition, while tribal warfare is virtually continuous.”
This shouldn’t be so astonishing, really. Plus:
A 2012 study in The Philosophical Transactions of the Royal Society B noted that the “anthropological record indicates that approximately 85 percent
of human societies have permitted men to have more than one wife.” Yet in modern times normative monogamy has become dominant around the
globe, increasing social peace by reducing competition among men. The researchers further noted, “Compared to monogamous societies, polygamous cultures see more rape, kidnapping, murder, assault, robbery, fraud, child neglect and child abuse.”
It is not too far of a stretch to think that although societies practicing marital monogamy are historically fewer in number, their comparatively stronger social solidarity has helped them out-grow and out-compete polygamous competitors. And the spread of monogamy has plausibly contributed to the lower levels of violence in the modern societies.
That shouldn’t be so surprising either.
