A double duty devolves on her; to educate them in the character of both father and mother; to form their principles and secure their property. But, alas! she has never thought, much less acted for herself. She has only learned to please* men, to depend gracefully on them; yet, encumbered with children, how is she to obtain another protector -- a husband to supply the place of reason? A rational man, for we are not treading on romantic ground, though he may think her a pleasing docile creature, will not choose to marry a family for love, when the world contains many more pretty creatures. What is then to become of her? She either falls an easy prey to some mean fortune-hunter, who defrauds her children of their paternal inheritance, and renders her miserable; or becomes the victim of discontent and blind indulgence. Unable to educate her sons, or impress them with respect; for it is not a play on words to assert, that people are never respected, though filling an important station, who are not respectable; she pines under the anguish of unavailing impotent regret. The serpent's tooth enters into her very soul, and the vices of licentious youth bring her with sorrow, if not with poverty also, to the grave.
'This principle being established, it follows that woman is expressly formed to please the man: if the obligation be reciprocal also, and the man ought to please in his turn, it is not so immediately necessary: his great merit is in his power, and he pleases merely because he is strong. This, I must confess, is not one of the refined maxims of love; it is, however, one of the laws of nature, prior to love itself.
'If woman be formed to please and be subjected to man, it is her place, doubtless, to render herself agreeable to him, instead of challenging his passion, The violence of his desires depends on her charms; it is by means of these she should urge him to the exertion of those powers which nature hath given him. The most successful method of exciting them, is, to render such exertion necessary by resistance; as, in that case, self-love is added to desire, and the one triumphs in the victory which the other obliged to acquire. Hence arise the various modes of attack and defence between the sexes; the boldness of one sex and the timidity of the other; and, in a word, that bashfulness and modesty with which nature hath armed the weak, in order to subdue the strong.' -- Rousseau's Emilius.
