From
The Origin of the Family,
Private Property and the State
p . . . Thus full freedom in marriage can become generally operative only when the abolition of capitalist production, and of the property relations created by it, has removed all those secondary economic considerations which still exert so powerful an influence on the choice of a partner. Then, no other motive remains than mutual affection....
p ... With the disappearance of the economic considerations which compelled women to tolerate the customary infidelity of the men-the anxiety about their own livelihood and even more about the future of their children-the equality of woman thus achieved will, judging from all previous experience, result far more effectively in the men becoming really monogamous than in the women becoming polyandrous.
p What will most definitely disappear from monogamy, however, is all the characteristics stamped on it in consequence of its having arisen out of property relationships. These are, first, the dominance of the man, and secondly, the indissolubility of marriage. The predominance of the man in marriage is simply a consequence of his economic predominance and will vanish with it automatically. The indissolubility of marriage is partly the result of the economic conditions under which monogamy arose, and partly a tradition from the time when the connection between these economic conditions and monogamy was not yet correctly understood and was exaggerated by religion. Today it has been breached a thousandfold. If only marriages that are based on love are moral, then, also, only 37 those are moral in which love continues. The duration of the urge of individual sex love differs very much according to the individual, particularly among men; and a definite cessation of affection, or its displacement by a new passionate love, makes separation a blessing for both parties as well as for society. People will only be spared the experience of wading through the useless mire of divorce proceedings.
But what will be added? That will be settled after a new generation has grown up: a generation of men who never in all their lives have had occasion to purchase a woman’s surrender either with money or with any other means of social power, and of women who have never been obliged to surrender to any man out of any consideration other than that of real love, or to refrain from giving themselves to their beloved for fear of the economic consequences. Once such people appear, they will not care a rap about what we today think they should do. They will establish their own practice and their own public opinion, conformable therewith, on the practice of each individual —and that’s the end of it. ...
