Among the higher animals the herd and the family are not complementary to one another, but antagonistic. — Friedrich Engels

With this as its basic constitution, civilization achieved things of which gentile society was not even remotely capable. But it achieved them by setting in motion the lowest instincts and passions in man and developing them at the expense of all his other abilities. From its first day to this, sheer greed was the driving spirit of civilization; wealth and again wealth and once more wealth, wealth, not of society, but of the single scurvy individual–here was its one and final aim. If at the same time the progressive development of science and a repeated flowering of supreme art dropped into its lap, it was only because without them modern wealth could not have completely realized its achievements.

We are now approaching a , in which the old economic foundations of monogamy will disappear just as surely as those of its complement, prostitution. Monogamy arose through the concentration of considerable wealth in one hand — a man's hand — and from the endeavor to bequeath this wealth to the children of this man to the exclusion of all others. This necessitated monogamy on the woman's, but not on the man's part. Hence this monogamy of women in no way hindered open or secret polygamy of men. Now, the impending social revolution will reduce this whole care of inheritance to a minimum by changing at least the overwhelming part of permanent and inheritable wealth—the means of production—into social property. Since monogamy was caused by economic conditions, will it disappear when these causes are abolished?

One might reply, not without reason: not only will it not disappear, but it will rather be perfectly realized. For with the transformation of the means of production into collective property, wagelabor will also disappear, and with it the proletariat and the necessity for a certain, statistically ascertainable number of women to surrender for money. Prostitution disappears and monogamy, instead of going out of existence, at last becomes a reality—for men also.

At all events, the situation will be very much changed for men. But also that of women, and of all women, will be considerably altered. With the transformation of the means of production into collective property the monogamous family ceases to be the of society. The private household changes to a social industry. The care and education of children become? a public matter. Society cares equally well for all children, legal or illegal. This removes the care about the "consequences" which now forms the essential social factor—moral and economic—hindering a girl to surrender unconditionally to the beloved man. Will not this be sufficient cause for a gradual rise of a more unconventional intercourse of the sexes and a more lenient public opinion regarding virgin honor and female shame? And finally, did we not see that in the modern world monogamy and prostitution, though antitheses, are inseparable and poles of the same social condition? Can prostitution disappear without engulfing at the same time monogamy?
