This rapid obscuration of a reputation which was genuine, for Lowe's powers had been amply proved, was due to no accident, and was apparent long before mental decay set in. The causes lay in himself. One cause was purely physical. He was excessively short-sighted, so much so that when he was writing a letter, his nose was apt to rub out the words his pen had traced; and this defect shut him out from all that knowledge of individual men and of audiences which is to be obtained by watching their faces. Mr. Gladstone, who never seemed to resent Lowe's attacks, and greatly admired his gifts--it was not so clear that Lowe reciprocated the admiration--used to relate that on one occasion when a foreign potentate met the Minister in St. James's Park and put out his hand in friendly greeting, Lowe repelled his advances, and when the King said, "But, Mr. Lowe, you know me quite well," he answered, "Yes, indeed, I know you far too well, and I don't want to have anything more to do with you." He had mistaken the monarch for a prominent politician with whom he had had a sharp encounter on a deputation a few days before! For social purposes Lowe might almost as well have been blind; yet he did not receive that kind of indulgence which is extended to the blind. In the interesting fragment of autobiography which he left, he attributes his unpopularity entirely to this cause, declaring that he was really of a kindly nature, liking his fellow-men just as well as most of them like one another.[42] But in truth his own character had something to answer for. Without being ill-natured, he was deemed a hard-natured man, who did not appear to consider the feelings of others. He had indeed a love of mischief, and gleefully tells in his autobiography how, when travelling in his youth through the Scottish Highlands, he drove the too self-conscious Wordsworth wild by his incessant praise of Walter Scott.[43] He had not in political life more than his fair share of personal enmities. One of them was Disraeli's. They were not unequally matched. Lowe was intellectually in some respects stronger, but he wanted Disraeli's skill in managing men and assemblies. Disraeli resented Lowe's sarcasms, and on one occasion, when the latter had made an indiscreet speech, went out of his way to inflict on him a personal humiliation. Nor was this Lowe's only defect. Powerful in attack, he was feeble in defence. Terrible as a critic, he had, as his official career showed, little constructive talent, little tact in shaping or recommending his measures. Unsteady or inconstant in purpose, he was at one moment headstrong, at another timid or vacillating. These faults, scarcely noticed when he was in Opposition, sensibly reduced his value as a minister and as a Cabinet colleague.
