His interest in the great things, so far from turning him away from the small things, seemed to quicken his sense of their significance. It was a noteworthy feature of his view of history that he should have held that the explanation of most of what has passed in the light is to be found in what has passed in the dark. He was always hunting for the key to secret chambers, preferring to believe that the grand staircase is only for show, and meant to impose upon the multitude, while the real action goes on in hidden passages behind. No one knew so much of the gossip of the past; no one was more intensely curious about the gossip of the present, though in his hands it ceased to be gossip and became unwritten history. One was sometimes disposed to wonder whether he did not think too much about the backstairs. But he had seen a great deal of history in the making. The passion for acquiring knowledge which his German education had fostered ended by becoming a snare to him, because it checked his productive powers. Not that learning burdened him, or clogged the soaring pinions of his mind. He was master of all he knew. But acquisition absorbed so much of his time that little was left for literary composition. (Doellinger saw the danger, for he observed that if Acton did not write a great book before he reached the age of forty, he would never do so.) It made him think that he could not write on a subject till he had read everything, or nearly everything, that others had written about it. It developed the habit of making extracts from the books he read, a habit which took the form of accumulating small slips of paper on which these extracts were written in his exquisitely neat and regular hand, the slips being arranged in cardboard boxes according to their subjects. He had hundreds of these boxes; and though much of their contents must no doubt be valuable, the time spent in distilling and bottling the essence of the books whence they came, might have been better spent in giving to the world the ideas which they had helped to evoke in his own mind. If one may take the quotations appended to his inaugural lecture as a sample of those he had collected, many of them were not exceptionally valuable, and did little more than show how the same idea, perhaps no recondite one, might be expressed in different words by different persons. When one read some article he had written, garnished and even overloaded with citations, one often felt that his own part was better, both in substance and in form, than the passages which he had culled from his predecessors. It becomes daily more than ever true that the secret of historical composition is to know what to neglect, since in our time it has become impossible to exhaust the literature of most subjects, and, as respects the last two centuries, to exhaust even the original authorities. Yet how shall one know what to neglect without at least a glance of inspection? Acton was unwilling to neglect anything; and his
