If we look back for a moment to the primitive stages of society, we may picture to ourselves the surface of the earth sparsely and scantily covered with wandering tribes of savages, rude in morals and manners, narrow and monotonous in experience, sustaining life very much as lower animals sustain it, by gathering wild fruits or slaying wild game, and waging chronic warfare alike with powerful beasts and with rival tribes of men. [Sidenote: Political history is the history of nation-making]
In the widest sense the subject of political history is the description of the processes by which, under favourable circumstances, innumerable such primitive tribes have become welded together into mighty nations, with elevated standards of morals and manners, with wide and varied experience, sustaining life and ministering to human happiness by elaborate arts and sciences, and putting a curb upon warfare by limiting its scope, diminishing its cruelty, and interrupting it by intervals of peace. The story, as laid before us in the records of three thousand years, is fascinating and absorbing in its human interest for those who content themselves with the study of its countless personal incidents, and neglect its profound philosophical lessons. But for those who study it in the scientific spirit, the human interest of its details becomes still more intensely fascinating and absorbing. Battles and coronations, poems and inventions, migrations and martyrdoms, acquire new meanings and awaken new emotions as we begin to discern their bearings upon the solemn work of ages that is slowly winning for humanity a richer and more perfect life. By such meditation upon men’s thoughts and deeds is the understanding purified, till we become better able to comprehend our relations to the world and the duty that lies upon each of us to shape his conduct rightly.
