the three main stages of human development. For savagery group marriage, for barbarism the pairing family, for civilization monogamy supplemented by adultery and prostitution. Between the pairing family and monogamy, in the higher stage of barbarism, the rule of men over female slaves and polygamy is inserted.
As we proved by our whole argument, the progress visible in this chain of phenomena is connected with the peculiarity of more and more curtailing the sexual freedom of the group marriage for women, but not for men. And group marriage is actually practised by men to this day. What is considered a crime for women and entails grave legal and social consequences for them, is considered honorable for men or in the worst case a slight moral blemish born with pleasure. But the more traditional hetaerism is changed in our day by capitalistic production and conforms to it, the more hetaerism is transformed into undisguised prostitution, the more demoralizing are its effects. And it demoralizes men far more than women. Prostitution does not degrade the whole female sex, but only the luckless women that become its victims, and even those not to the extent generally assumed. But it degrades the character of the entire male world. Especially a long engagement is in nine cases out of ten a perfect training school of adultery.
