Gaston Bouthol founded a particular sociology known as polemology. Skeptical about the pacifism and critic of the juridical illusion of the international regulation of the peace-phenomenon, he studied the war-phenomenon without moralising prejudices. Polemology, that involves a critic of culture, is focused on the social function of war, known as the most important institution of destruction. The study of major wars enabled him to raise an hypothesis that foresees the periodicity of wars.
