It may be said that the abstract Utilitarian doctrine reached its high-water mark in Mill's book on the Subjection of Women, to which Mr. Stephen allots one section of a chapter. The book is a particular enlargement upon Mill's general view that it is a pestilent error to regard such marked distinctions of human character as sex or race as innate and in the main indelible. What is called the nature of women he treats as an artificial thing, an isolated fact which need not at any rate be recognised by law; the proper test was, he argued, to leave free competition to determine whether the distinction is radical or merely the result of external circumstance. But, as Mr. Stephen answers, such a plain physiological difference is at least not negligible; and competition between the sexes may favour the despotism of the stronger, while complete independence on both sides implies freedom to separate at will; and Mill had only glanced evasively at the question of divorce. Here, again, is a theory which the pressure of social conditions, much more than abstract reasoning, is bringing more and more into prominence with our own generation. On the wider and more complicated question of race distinctions Mill never worked out his argument against their indelibility into a regular treatise; nor could he foresee the increasing influence upon contemporary politics that is now exercised by racial feelings and their claims to recognition. In the eighteenth century the French Encyclopédistes, who were the direct philosophic ancestors of the Utilitarians, regarded frontiers, classes, and races as so many barriers against the spread of universal fraternity; and the revolutionary government took up the idea as a war-cry. The armies of the French Republic proclaimed the rights of the people in all countries, until Napoleon turned the democratic doctrine into the form of Imperialism. M. Eugène de Vogüé has told us recently that this armed propaganda produced a reaction in Europe toward that strong sentiment of nationality which has been vigorously manifested during the second half of the nineteenth century. The assertion of separate nationalities, by the demand for political autonomy and by the attempt to revive the public teaching of obscure languages, is the form taken in western and central Europe by the problem of race. No movement could be more contrary to the views or anticipations of the Utilitarians, for whom it would have been merely a recrudescence of one of those inveterate and unreasoning prejudices which still retard human progress, a fiction accepted by indolent thinkers to avoid the trouble of investigating the true causes that modify human character. Yet not only is national particularism making a fresh stir in Europe, but the spread of European dominion over Asia has forced upon our attention the immense practical importance of racial distinctions. We find that they signify real and profound characteristics; the European discovers that in Asia he is himself one of a ruling race, and thereby isolated among the other groups into which the population is subdivided. If he is a sound Utilitarian he will nevertheless cherish the belief that economical improvements, public instruction, good laws, and regular administration will obliterate antipathies, eradicate irrational prejudices, and reconcile Asiatic folk to the blessings of scientific civilisation. But he will confess that it is a stubborn element, if not innate yet very like such a quality; if not ineffaceable yet certain to outlast his dominion. It is at least remarkable that Mill's protest against explaining differences of character by race, to which Buckle 'cordially subscribed,' should have been answered in our time by a clamorous demand for the recognition of those very differences, and by an increasing tendency to admit them.
