If this general principle of social and economical science is not true; if individuals, with such help as they can derive from the opinion of those who know them, are not better judges than the law and the government, of their own capacities and vocation; the world cannot too soon abandon this principle, and return to the old system of regulations and disabilities. But if the principle is true, we ought to act as if we believed it, and not to ordain that to be born a girl instead of a boy, any more than to be born black instead of white, or a commoner instead of a nobleman, shall decide the person's position through all life--shall interdict people from all the more elevated social positions, and from all, except a few, respectable occupations. Even were we to admit the utmost that is ever pretended as to the superior fitness of men for all the functions now reserved to them, the same argument applies which forbids a legal qualification for members of Parliament. If only once in a dozen years the conditions of eligibility exclude a fit person, there is a real loss, while the exclusion of thousands of unfit persons is no gain; for if the constitution of the electoral body disposes them to choose unfit persons, there are always plenty of such persons to choose from. In all things of any difficulty and importance, those who can do them well are fewer than the need, even with the most unrestricted latitude of choice: and any limitation of the field of selection deprives society of some chances of being served by the competent, without ever saving it from the incompetent.
