Yet it may be, that, with the smaller general bulk and the muscular fineness, and the preponderance of brain and nervous system in net bulk over the fleshy and osseous parts of the organism, which generally, though by no means always, characterises the female as distinguished from the male of the human species, there do go mental qualities which will peculiarly fit her for the labours of the future. It may be, that her lesser possession of the mere muscular and osseous strength, which were the elements of primary importance and which gave dominance in one stage of human growth, and which placed woman at a social disadvantage as compared with her companion, will, under new conditions of life, in which the value of crude mechanical strength as distinguished from high vitality and strong nervous activity is passing away, prove as largely to her advantage, as his muscular bulk and strength in the past proved to the male. It is quite possible, in the new world which is arising about us, that the type of human most useful to society and best fitted for its future conditions, and who will excel in the most numerous forms of activity, will be, not merely the muscularly powerful and bulky, but the highly versatile, active, vital, adaptive, sensitive, physically fine-drawn type; and, as that type, though, like the muscularly heavy and powerful, by no means peculiar to and confined to one sex, is yet rather more commonly found in conjunction with a female organism, it is quite possible that, taken in the bulk and on the whole, the female half of humanity may, by virtue of its structural adaptions, be found most fitted for the bulk of human labours in the future! As with individuals and races, so also with sexes, changed social conditions may render exactly those subtile qualities, which in one social state were a disadvantage, of the highest social advantage in another.
