When we are about to speak of the institutions of a country at any given period, we must first understand what was the state of persons in that country at that period; for words are very deceptive. History, when speaking of the English nation or the Spanish nation, comprises under that name all the individuals who inhabit the country; but when we examine into the real state of the case, we quickly discover that the facts which history applies to an entire country, actually belong only to a very small section of its inhabitants. It is the work of civilization to raise up, from time to time, a greater number of men to take an active part in the great events which agitate the society of which they are members. As civilization advances, it reaches new classes of individuals, and gives them a place in history. The different conditions of society thus tend, not to confusion, but to arrangement, under different forms and in different degrees, in that superior region of society by which history is made. The first question to be solved, then, is that of the state of persons; we must precisely understand which are those classes that really figure in history. Then will occur this other question: What are the institutions in accordance with which that political nation acts, which alone furnishes subject-matter for history? {33} When we address the first question to antiquity, we find, as in Modern Europe, one great classification: freemen and slaves. But there is this difference that, in antiquity, slavery continued stationary and immutable. Its unchangeableness in this particular, was one of the principal characteristics of ancient civilization. Individuals were emancipated; but the great mass of slaves remained in bondage, everlastingly condemned to the same social nonentity. In Modern Europe, social conditions have been in a state of perpetual fluctuation; numerous masses of men have fallen into slavery, while others have emerged therefrom; and this alternation of liberty and servitude is a novel and important fact in the history of civilization.
