To insist that all Jews, and none but Jews, should lead and instruct in religious matters; that all Englishmen, and none but Englishmen, should engage in trade; that each German should make his living by music, and none but a German allowed to practise it, would drive to despair the unfortunate individual Englishman, whose most marked deficiency might be in the direction of finance and bartering trade power; the Jew, whose religious instincts might be entirely rudimentary; or the German, who could not distinguish one note from another; and the society as a whole would be an irremediable loser, in one of the heaviest of all forms of social loss--the loss of the full use of the highest capacities of all its members.
It may be that with sexes as with races, the subtlest physical difference between them may have their fine mental correlatives; but no abstract consideration of the human body in relation to its functions of sex can, in the present state of our knowledge, show us what intellectual capacities tend to vary with sexual structure, and nothing in the present or past condition of male and female give us more than the very faintest possible indication of the relation of their intellectual aptitudes and their sexual functions.

And even were it proved by centuries of experiment that with the possession of the uterine function of sex tends to go exceptional intellectual capacity in the direction of mathematics rather than natural history, or an inclination for statecraft rather than for mechanical invention; were it proved that, generally speaking and as a whole, out of twenty thousand women devoting themselves to law and twenty thousand to medicine, they tended to achieve relatively more in the field of law than of medicine, there would yet be no possible healthy or rational ground for restricting the activities of the individual female to that line in which the average female appeared rather more frequently to excel.
(Minds not keenly analytical are always apt to mistake mere correlation of appearance with causative sequence.

We have heard it gravely asserted that between potatoes, pigs, mud cabins and Irishmen there was an organic connection: but we who have lived in Colonies, know that within two generations the pure-bred descendant of the mud cabiner becomes often the successful politician, wealthy financier, or great judge; and shows no more predilection for potatoes, pigs, and mud cabins than men of any other race.) That even one individual in a society should be debarred from undertaking that form of social toil for which it is most fitted, makes an unnecessary deficit in the general social assets.

That one male Froebel should be prohibited or hampered in his labour as an educator of infancy, on the ground that infantile instruction was the field of the female; that one female with gifts in the direction of state administration, should be compelled to instruct an infants' school, perhaps without the slightest gift for so doing, is a running to waste of social life-blood.
Free trade in labour and equality of training, intellectual or physical, is essential if the organic aptitudes of a sex or class are to be determined.

And our demand today is that natural conditions, inexorably, but beneficently, may determine the labours of each individual, and not artificial restrictions.
As there is no need to legislate that Hindus, being generally supposed to have a natural incapacity for field sports, shall not betake themselves to them--for, if they have no capacity, they will fail; and, as in spite of the Hindus' supposed general incapacity for sport, it is possible for an individual Hindu to become the noted batsman of his age; so, also, there is no need to legislate that women should be restricted in her choice of fields of labour; for the organic incapacity of the individual, if it exist, will legislate far more powerfully than any artificial, legal, or social obstruction can do; and it may be that the one individual in ten thousand who selects a field not generally sought by his fellows will enrich humanity by the result of an especial genius.
Allowing all to start from the one point in the world of intellectual culture and labour, with our ancient Mother Nature sitting as umpire, distributing the prizes and scratching from the lists the incompetent, is all we demand, but we demand it determinedly.
