The indissolubility of marriage is partly the consequence of economic conditions, under which monogamy arose, partly tradition from the time where the connection between this economic situation and monogamy, not yet clearly understood, was carried to extremes by religion. To-day, it has been perforated a thousand times. If marriage founded on love is alone moral, then it follows that marriage is moral only as long as love lasts. The duration of an attack of individual sexlove varies considerably according to individual disposition, especially in men. A positive cessation of fondness or its replacement by a new passionate love makes a separation a blessing for both parties and for society. But humanity will be spared the useless wading through the mire of a divorce case. What we may anticipate about the adjustment of sexual relations after the impending downfall of capitalist production is mainly of a negative nature and mostly confined to elements that will disappear. But what will be added? That will be decided after a new generation has come to maturity: a race of men who never in their lives have had any occasion for buying with money or other economic means of power the surrender of a woman; a race of women who have never had any occasion for surrendering to any man for any other reason but love, or for refusing to surrender to their lover from fear of economic consequences. Once such people are in the world, they will not give a moment's thought to what we to-day believe should be their course. They will follow their own practice and fashion their own public opinion about the individual practice of every person--only this and nothing more. But let us return to Morgan from whom we moved away a considerable distance. The historical investigation of social institutions developed during the period of civilization exceeds the limits of his book. Hence the vicissitudes of monogamy during this epoch occupy him very briefly. He also sees in the further development of the monogamous family a progress, an approach to perfect equality of the sexes, without considering this aim fully realized. But he says: "When the fact is accepted that the family has passed through four successive forms, and is now in a fifth, the question at once arises whether this form can be permanent in the future. The only answer that can be given is that it must advance as society advances, and change as society changes, even as it has done in the past. It is the creature of the social system, and will reflect its culture. As the monogamian family has improved greatly since the commencement of civilization, and very sensibly in modern times, it is at least supposable that it is capable of still farther improvement until the equality of the sexes is attained. Should the monogamian family in the distant future fail to answer the requirements of society, assuming the continuous progress of civilization, it is impossible to predict the nature of its successor."
