In the course of our inquiry, we have had frequent occasion to lament the disorder and anarchy of European society, and to complain of the difficulty of analysing and depicting a society so scattered, incohesive, and discordant. We have longed for, and impatiently invoked, the era of general interests, of order, and of social unity. We have now reached it, and are entering upon the epoch in which everything is summed into general facts and general ideas, upon the very epoch of order and unity. We there, however, encounter a difficulty of another kind. It has hitherto required great pains to link facts together, to place them in their proper stations, to seize what they possessed in common, and unfold some appearance of a whole. In modern Europe, things are in an opposite vein. All the elements and incidents of the social state are modified by, and act and react upon, each other; the mutual relations of men are far more numerous and complicated; and the same multiplicity and entanglement occur in their relations with the government of the state, in the relations of states amongst themselves, and in the ideas and in all the workings of the human mind. In the periods we have passed through, a great number of facts appeared isolated, alien to each other, and without reciprocal influence. Now, we have no more isolation; all things meet, commingle, and vary as they meet. Can anything be conceived more difficult than to distinguish the veritable unity amid such a diversity, to determine the bent of a movement so extended and complex, to present so prodigious a throng of different elements, all closely linked together, in a general summary; in a word, to predicate the general predominant fact which sums up and expresses a long series of facts, which is the characteristic of an epoch, and the faithful expression of its influence and its action in the history of civilisation? We shall quickly perceive the extent of this difficulty in the great event which has now to occupy our attention. We encountered in the twelfth century an event, religious in its origin, if rather the reverse in its nature--I mean the Crusades. Notwithstanding the vastness of the event, its long duration, and the variety of circumstances it produced, it was an easy task to unravel its general character, and to determine with some precision its unity and influence. We have at present to consider the religious revolution of the sixteenth century, that which is commonly called the Reformation. {198} Allow me here to premise, that I shall make use of the word _reformation_, as of a simple and settled term, synonymous with _religious revolution_, and without implying a judgment of its nature. Thus on the threshold we perceive how difficult it is to assign the veritable character of that great crisis--to state in a general form what it was, and what it effected.
