Personal Aggressiveness as a Source of War

Abstract

The unprecedented slaughter of the First World War, and the fear, in the following two decades, that a further, still more murderous conflict might follow, brought new attempts to assess how far war resulted from ineradicable facets of human nature. This question was now increasingly considered, not in the general speculations of philosophers and political writers, but in the pronouncements of psychologists claiming to base their findings on a more scientific foundation.
