All minds of the first quality move and grow; they have a susceptibility to many sorts of new impressions, a mobility, a feeling outwards, which makes it impossible for them to remain in the stern fixity of an early implanted set of dogmas, whether philosophic or religious. In stoical tenacity of character, as well as in intellectual originality and concentrated force of understanding, some of those who knew both tell us that Mr. Mill was inferior to his father. But who does not feel in the son the serious charm of a power of adaptation and pliableness which we can never associate with the hardy and more rigorous nature of the other? And it was just because he had this sensibility of the intellect, that the history of what it did for him is so edifying a performance for a people like ourselves, among whom that quality is so extremely uncommon. For it was the sensibility of strength and not of weakness, nor of mere over-refinement and subtlety. We may estimate the significance of such a difference, when we think how little, after all, the singular gifts of a Newman or a Maurice have done for their contemporaries, simply because these two eminent men allowed consciousness of their own weakness to 'sickly over' the spontaneous impulses of their strength. The wonder is that the reaction against such an education as that through which James Mill brought his son,--an education so intense, so purely analytical, doing so much for the reason and so little for the satisfaction of the affections,--was not of the most violent kind. The wonder is that the crisis through which nearly every youth of good quality has to pass, and from which Mr. Mill, as he has told us, by no means escaped, did not land him in some of the extreme forms of transcendentalism. If it had done so the record of the journey would no doubt have been more abundant in melodramatic incidents. It would have done more to tickle the fancy of 'the present age of loud disputes but weak convictions.' And it might have been found more touching by the large numbers of talkers and writers who seem to think that a history of a careful man's opinions on grave and difficult subjects ought to have all the rapid movements and unexpected turns of a romance, and that a book without rapture and effusion and a great many capital letters must be joyless and disappointing. Those of us who dislike literary hysteria as much as we dislike the coarseness that mistakes itself for force, may well be glad to follow the mental history of a man who knew how to move and grow without any of these reactions and leaps on the one hand, or any of that overdone realism on the other, which may all make a more striking picture, but which do assuredly more often than not mark the ruin of a mind and the nullification of a career.
