Although the twelfth century resembled the nineteenth in vastness of achievement, it differed from the nineteenth in the quality of that achievement, and in the nature of the forces which made it possible. Of course the vigour of human will is the prime mover in both cases. In the twelfth century men felt that their strength had been magnified not so much by new processes giving them an increased command over physical nature as by moral forces suddenly making them aware of unsuspected strength within themselves. I do not mean that the nineteenth century felt that it possessed no new elements of moral strength. It did. The ideas of the American and French Revolution thrilled it profoundly; to a lesser extent it was touched by a limited but nevertheless keen, new, sympathy with those very Middle Ages with which we are concerned. Nor do I mean that the Middle Ages enjoyed no greater power over material things than had been possessed by the simple and childlike Dark Ages immediately preceding them. I do say that in the twelfth century, as compared with the nineteenth, the sense of new power over physical nature played a lesser, and the confidence in new powers within man’s own nature played a correspondingly greater, part. Two causes brought about this greater importance of the moral as compared with the physical factors of power. First, the twelfth century successes were, in all outward and secular things, no more than the partial reconquest of the Roman order which, after a fashion, men still remembered. Whereas the nineteenth century, instead of partly restoring that which had been, and had then been lost, conquered nature and barbarism in regions where such conquest had never been attempted. Hence the twelfth century in the full flush of its achievement was less subject to pride and the illusions which wait upon pride. Second, the moral (and intellectual) life of the twelfth century revolved about a single many-sided institution, the Church, which affected all departments of human life. It is the task of this chapter to set the stage for the events which follow. The reader must have a notion of the slack and sunken age of Gerbert (the great Pope of the year 1000), secondly the vigorous fighting age of Hildebrand and the great Norman chiefs, of the First Crusade and the Song of Roland, that is, the later eleventh century. Next he must grasp the twelfth century itself, Abelard, the teaching of the Roman law at Bologna, the enrichment and refinement of life, chivalry, “feminism,” and the continuing quarrel of the central and all-pervasive Church with the developing civil governments. Finally, towards the end of the century, he must appreciate the beginnings of the Gothic, the rise of strong and turbulent towns and guilds, and the promise of the long and fruitful marriage of government with the idea of nationality.
