When in 1886 Mr. Gladstone made his great attempt to settle the Irish question by Home Rule, Lord Acton gave him a zealous and cordial support. Although, as we have seen, he was far from holding the doctrine of nationality in an unqualified form, he had grasped for many years with increasing strength the conviction that Ireland could be orderly and peaceably governed by Irishmen alone. So far back as October 1881, when the Liberal Government and the Land League were in open hostility, and Mr. Parnell was arrested under the Coercion Act, he wrote, "The treatment of Home Rule as an idea conceivably reasonable (in the speech at Leeds) which was repeated at the Guildhall, delighted me." There were not many readers besides Lord Acton who discerned at that time the trend of Mr. Gladstone's ideas. But a very few months later, in February 1882, Mr. Gladstone, speaking on the Address, used language of a much more significant kind, to Lord Acton's great delight. "I have long wished," he wrote on the 20th of February, "for that declaration about self-government… The occasion last week gave extraordinary weight to the words… The risk is that he may seem to underrate the gravity of a great constitutional change in the introduction of a federal element." Lord Acton, it will be observed, much as he desired the change, did not ignore its risks, or even its perils. When the decisive moment came, which Mr. Morley has described with so much eloquence and power ("Life of Gladstone," vol. iii. pp. 311-12), Lord Acton sounded a note of warning in the midst of his felicitations. "From the point of view of the ages," he wrote on the 18th of March 1886, "it is the sublime crown of his work, and there is a moral grandeur about it which will, I hope, strengthen and console him under any amount of difficulty, and even disaster." It was this faculty of seeing the case against his own most deeply cherished principles and predilections which made Lord Acton so valuable a friend and counsellor to Mr. Gladstone. Mr. Gladstone's splendid enthusiasm, and indomitable optimism, sometimes led him to ignore obstacles against which he might have provided. Acton, whose temperament was critical, as his mind was judicial, pointed out, with the sincerity of true friendship, though with unfailing tact, the clouds above, and the rocks ahead. No man admired Mr. Gladstone more. No man flattered him less.
The following letter to Mrs. Drew expresses his opinion at the time, and also the judgment of a distinguished Italian statesman who was always friendly to England: —
"Your letter comes in the midst of the living echoes of the speech, and of the uncertainty that follows, and does not quite relieve my feeling of apprehension. Rome is not a good place for accurate news, and I hope for more letters at Cannes in a couple of days. My old friend, Minghetti, is sinking under an incurable illness. The other night, when several people were attacking me about the Irish Bill, he said, very solemnly and in his best Italian: 'The one will be happy even if he fails, and the other will repent even of his success.' The other was Bismarck. Next morning came Herbert's letter saying that he feels that for himself the best thing would be defeat.
"I hope that there is not any real inconsistency in my language or in my thoughts at this crisis. I am more decidedly in favour of the principle of the measure than anybody; and there can hardly be one among your father's friends who urged it more decidedly, though some followed more or less contentedly. The Bill is better than I sometimes expected it to be, on one or two important points. It is not only right in my eyes, but glorious as the summit of his career, and if I was on the spot I should be the warmest and the most convinced of its supporters.
"But what makes it more admirable to me is that the stimulus is not hope but duty; that it is very much more clearly dictated by principle than by expediency, that the supreme motive is not strongly sustained by sordid calculation. I do not see a real likelihood of its succeeding in this Session, and I am not sanguine about success in Ireland.
"Arguments founded on the presumed good qualities of the Irish do not go very far with me, and I am ready to find the vices of the national character incurable. Especially in a country where religion does not work, ultimately, in favour of morality; therefore I am not hopeful, and it is with a mind prepared for failure and even disaster that I persist in urging the measure."
His adhesion to the cause, though it had no weight with the mass of electors, who did not know his name, had a deep meaning of another kind. When many men of the lettered, scientific, and learned classes left the Liberal party rather than vote for Home Rule, one of the few English names that enjoyed a European reputation did something to counterbalance others which were paraded so often that they seemed indefinitely numerous.
Lord Acton, however, did not come forward as a popular champion of Home Rule, for which he could have furnished a host of historic precedents. In the sphere of action he was too apt to distrust himself. The House of Lords was not favourable for the purpose, and he never appeared on public platforms. He was more congenially occupied in founding the English Historical Review, of which the late Bishop Creighton, then Professor of Ecclesiastical History at Cambridge, was the first editor. In 1887 he criticised, not without severity, the third and fourth volumes of the editor's great work on the Papacy. Some editors might have demurred to the insertion of the article. But Creighton was far above all petty and personal feelings of that or any kind. Among the other books noticed by Acton in the Historical Review were Seeley's "Life of Napoleon," Bright's "History of England" (by the Master of University),
