From The Lessons of History by Will and Ariel Durant: “In the last 3,421 years of recorded history only 268 have seen no war.” The Durants don’t say how they came up with the number. I would love to have the list, and know in each case whether peace had succeeded or war had failed. When people talk of the history of war and peace, the pessimist says we always fall back on war; the optimistist, on peace.
