Leaving these subversive dreams, we find a natural principle which, by determining the practical obligations of the Active to the Sympathetic sex, averts this danger. It is a principle which no philosophy but Positivism has been sufficiently real and practical to bring forward systematically for general acceptance. It is no new invention, however, but a universal tendency, confirmed by careful study of the whole past history of Man. The principle is, that Man should provide for Woman. It is a natural law of the human race; a law connected with the essentially domestic character of female life. We find it in the rudest forms of social life; and with every step in the progress of society its adoption becomes more extensive and complete. A still larger application of this fundamental principle will meet all the material difficulties under which women are now labouring. All social relations, and especially the question of wages, will be affected by it. The tendency to it is spontaneous; but it also follows from the high position which Positivism has assigned to Woman as the sympathetic element in the spiritual power. The intellectual class, in the same way, has to be supported by the practical class, in order to have its whole time available for the special duties imposed upon it. But in the case of women, the obligation of the other sex is still more sacred, because the sphere of duty in which protection for them is required, is the home. The obligation to provide for the intellectual class, affects society as a whole; but the maintenance of women is, with few exceptions, a personal obligation. Each individual should consider himself bound to maintain the woman he has chosen to be his partner in life. There are cases, however, in which men should be considered collectively responsible for the support of the other sex. Women who are without husband or parents should have their maintenance guaranteed by society; and this not merely from compassion for their dependent position, but with the view of enabling them to render public service of the greatest moral value.
