A conception of military life resembling that of medieval chivalry is found nearly everywhere, notably with the Hindus of the Mahâbhârata and in Japan. Warlike aristocracies need an ideal form of manly perfection. The aspiration to a pure and beautiful life, expressed in the Kalokagathia of the Hellenes, in the Middle Ages gives birth to chivalry. And during several centuries that ideal remains a source of energy, and at the same time a cloak for a whole world of violence and self-interest.
