In this epoch of full-grown history men have not acquiesced in the given conditions of their lives. Taking little for granted they have sought to know the ground they stand on, and the road they travel, and the reason why. Over them, therefore, the historian has obtained an increasing ascendancy.[17] The law of stability was overcome by the power of ideas, constantly varied and rapidly renewed;[18] ideas that give life and motion, that take wing and traverse seas and frontiers, making it futile to pursue the consecutive order of events in the seclusion of a separate nationality.[19] They compel us to share the existence of societies wider than our own, to be familiar with distant and exotic types, to hold our march upon the loftier summits, along the central range, to live in the company of heroes, and saints, and men of genius, that no single country could produce. We cannot afford wantonly to lose sight of great men and memorable lives, and are bound to store up objects for admiration as far as may be;[20] for the effect of implacable research is constantly to reduce their number. No intellectual exercise, for instance, can be more invigorating than to watch the working of the mind of Napoleon, the most entirely known as well as the ablest of historic men. In another sphere, it is the vision of a higher world to be intimate with the character of Fénelon, the cherished model of politicians, ecclesiastics, and men of letters, the witness against one century and precursor of another, the advocate of the poor against oppression, of liberty in an age of arbitrary power, of tolerance in an age of persecution, of the humane virtues among men accustomed to sacrifice them to authority, the man of whom one enemy says that his cleverness was enough to strike terror, and another, that genius poured in torrents from his eyes. For the minds that are greatest and best alone furnish the instructive examples. A man of ordinary proportion or inferior metal knows not how to think out the rounded circle of his thought, how to divest his will of its surroundings and to rise above the pressure of time and race and circumstance,[21] to choose the star that guides his course, to correct, and test, and assay his convictions by the light within,[22] and, with a resolute conscience and ideal courage, to re-model and reconstitute the character which birth and education gave him.[23] [Sidenote: FOREIGN CONSTITUTIONS]
