Good, The Subjection of Women is online after all, just not at Project Gutenberg. So I’ll quote a passage from section one.

All causes, social and natural, combine to make it unlikely that women should be collectively rebellious to the power of men. They are so far in a position different from all other subject classes, that their masters require something more from them than actual service. Men do not want solely the obedience of women, they want their sentiments. All men, except the most brutish, desire to have, in the woman most nearly connected with them, not a forced slave but a willing one, not a slave merely, but a favourite. They have therefore put everything in practice to enslave their minds. The masters of all other slaves rely, for maintaining obedience, on fear; either fear of themselves, or religious fears. The masters of women wanted more than simple obedience, and they turned the whole force of education to effect their purpose. All women are brought up from the very earliest years in the belief that their ideal of character is the very opposite to that of men; not self will, and government by self-control, but submission, and yielding to the control of other. All the moralities tell them that it is the duty of women, and all the current sentimentalities that it is their nature, to live for others; to make complete abnegation of themselves, and to have no life but in their affections. And by their affections are meant the only ones they are allowed to have — those to the men with whom they are connected, or to the children who constitute an additional and indefeasible tie between them and a man. When we put together three things — first, the natural attraction between opposite sexes; secondly, the wife’s entire dependence on the husband, every privilege or pleasure she has being either his gift, or depending entirely on his will; and lastly, that the principal object of human pursuit, consideration, and all objects of social ambition, can in general be sought or obtained by her only through him, it would be a miracle if the object of being attractive to men had not become the polar star of feminine education and formation of character. And, this great means of influence over the minds of women having been acquired, an instinct of selfishness made men avail themselves of it to the utmost as a means of holding women in subjection, by representing to them meekness, submissiveness, and resignation of all individual will into the hands of a man, as an essential part of sexual attractiveness. Can it be doubted that any of the other yokes which mankind have succeeded in breaking, would have subsisted till now if the same means had existed, and had been so sedulously used, to bow down their minds to it? If it had been made the object of the life of every young plebeian to find personal favour in the eyes of some patrician, of every young serf with some seigneur; if domestication with him, and a share of his personal affections, had been held out as the prize which they all should look out for, the most gifted and aspiring being able to reckon on the most desirable prizes; and if, when this prize had been obtained, they had been shut out by a wall of brass from all interests not centring in him, all feelings and desires but those which he shared or inculcated; would not serfs and seigneurs, plebeians and patricians, have been as broadly distinguished at this day as men and women are? and would not all but a thinker here and there, have believed the distinction to be a fundamental and unalterable fact in human nature?

So much has changed since Mill wrote that, and yet women are still subject to unremitting social pressure to be sexually attractive before they are anything else.
