But the old doctor sighed, and told himself that the girl was most human, most affectionate; it was not impossible that, in spite of her apparent absence of certain domestic instincts, they had only lain dormant and were now awake. He could not bear that she should lose any happiness which might be hers; and the tender memory of the blessed companionship which had been withdrawn from his mortal sight only to be given back to him more fully as he had lived closer and nearer to spiritual things, made him shrink from forbidding the same sort of fullness and completion of life to one so dear as Nan. He tried to assure himself that while a man's life is strengthened by his domestic happiness, a woman's must either surrender itself wholly, or relinquish entirely the claims of such duties, if she would achieve distinction or satisfaction elsewhere. The two cannot be taken together in a woman's life as in a man's. One must be made of lesser consequence, though the very natures of both domestic and professional life need all the strength which can be brought to them. The decision between them he knew to be a most grave responsibility, and one to be governed by the gravest moral obligations, and the unmistakable leadings of the personal instincts and ambitions. It was seldom, Dr. Leslie was aware, that so typical and evident an example as this could offer itself of the class of women who are a result of natural progression and variation, not for better work, but for different work, and who are designed for certain public and social duties. But he believed this class to be one that must inevitably increase with the higher developments of civilization, and in later years, which he might never see, the love for humanity would be recognized and employed more intelligently; while now almost every popular prejudice was against his ward, then she would need no vindication. The wielder of ideas has always a certain advantage over the depender upon facts; and though the two classes of minds by no means inevitably belong, the one to women, and the other to men, still women have not yet begun to use the best resources of their natures, having been later developed, and in many countries but recently freed from restraining and hindering influences.
