A more perfect companionship, one on a higher intellectual level, or of more sustained mental activity, is nowhere recorded. Lewes's mercurial temperament contributed as much as the powerful mind of his consort to prevent their seclusion from degenerating into an owlish stagnation. To the very last (1878) he retained his extraordinary buoyancy. 'Nothing but death could quench that bright flame. Even on his worst days he had always a good story to tell; and I remember on one occasion in the drawing-room at Witley, between two bouts of pain, he sang through with great _brio_, though without much voice, the greater portion of the tenor part in the _Barber of Seville_, George Eliot playing his accompaniment, and both of them thoroughly enjoying the fun' (iii. 334). All this gaiety, his inexhaustible vivacity, the facility of his transitions from brilliant levity to a keen seriousness, the readiness of his mental response, and the wide range of intellectual accomplishments that were much more than superficial, made him a source of incessant and varied stimulation. Even those, and there were some, who thought that his gaiety bordered on flippancy, that his genial self-content often came near to shockingly bad taste, and that his reminiscences of poor Mr. Fitzball and the green-room and all the rest of the Bohemia in which he had once dwelt, were too racy for his company, still found it hard to resist the alert intelligence with which he rose to every good topic, and the extraordinary heartiness and spontaneity with which the wholesome spring of human laughter was touched in him. Lewes had plenty of egotism, not to give it a more unamiable name, but it never mastered his intellectual sincerity. George Eliot describes him as one of the few human beings she has known who will, in the heat of an argument, see, and straightway confess, that he is in the wrong, instead of trying to shift his ground or use any other device of vanity. 'The intense happiness of our union,' she wrote to a friend, 'is derived in a high degree from the perfect freedom with which we each follow and declare our own impressions. In this respect I know _no_ man so great as he--that difference of opinion rouses no egotistic irritation in him, and that he is ready to admit that another argument is the stronger the moment his intellect recognises it' (ii. 279). This will sound very easy to the dispassionate reader, because it is so obviously just and proper, but if the dispassionate reader ever tries, he may find the virtue not so easy as it looks. Finally, and above all, we can never forget in Lewes's case how much true elevation and stability of character was implied in the unceasing reverence, gratitude, and devotion with which for five-and-twenty years he treated her to whom he owed all his happiness, and who most truly, in his own words (ii. 76), had made his life a new birth.
