our branch of study has become progressive, so that the best master is quickly distanced by the better pupil #24. The Vatican archives alone, now made accessible to the world, filled 3239 cases when they were sent to France; and they are not the richest. We are still at the beginning of the documentary age, which will tend to make history independent of historians, to develop learning at the expense of writing, and to accomplish a revolution in other sciences as well. To men in general I would justify the stress I am laying on Modern History, neither by urging its varied wealth, nor the rupture with precedent, nor the perpetuity of change and increase of pace, nor the growing predominance of opinion over belief, and of knowledge over opinion, but by the argument that it is a narrative told of ourselves, the record of a life which is our own, of efforts not yet abandoned to repose, of problems that still entangle the feet and vex the hearts of men. Every part of it is weighty with inestimable lessons that we must learn by experience and at a great price, if we know not how to profit by the example and teaching of those who have gone before us, in a society largely resembling the one we live in #25. Its study fulfils its purpose even if it only makes us wiser, without producing books, and gives us the gift of historical thinking, which is better than historical learning #27. It is a most powerful ingredient in the formation of character and the training of talent, and our historical judgments have as much to do with hopes of heaven as public or private conduct. Convictions that have been strained through the instances and the comparisons of modern times differ immeasurably in solidity and force from those which every new fact perturbs, and which are often little better than illusions or unsifted prejudice #28.
