War, Peace, and Progress: Militarism and Pacifism in Evolutionary Thought, 1898-1920
Much of the academic literature written about the First World War has tended to revolve around questions of diplomacy, foreign policy, and the International System as it existed in Europe in the decades before the war began. To balance this, I analyze the intellectual history of evolutionary thought as it applied to the question of war, peace, and the alleged “pugnacity” of man before and during the war years. Many people viewed the world of international conflict through the lens of socio-biological progress and a “struggle for existence” among humans, nations, and races. By identifying three broad intellectual trends, I argue that these evolutionary narratives of the war question were diverse. Some used the language of human evolution to arguethat war was an inevitable engine of progress whereas others stressed different concepts in evolutionary science, such as cooperation, to make pacifist arguments. A third school of thought, the pessimists, argued that man was inherently warlike but that this instinct could be tamed. As the centennial anniversary of the July Crisis and the beginning of the First World War approaches, it is worth investigating the ideational “mood” of the era and the intellectual climate which allowed for such a devastating war to take place.
