I cannot enter into more details on this subject, but what I have said
will suffice to draw the attention of my readers to the action of

CHAPTER X

THE SEXUAL QUESTION IN RELATION TO MONEY AND PROPERTY PROSTITUTION,
PROXENETISM AND VENAL CONCUBINAGE

GENERAL REMARKS

In Chapter VI we have studied the historical development of human
marriage as a continuation of the phylogeny of our species, and we
have shown that marriage by purchase and different forms of polygamy
constitute a kind of intermediate stage and at the same time an
aberration of civilization, which has resulted from the association of
men, combined with the birth of individual property.

When we consider a being of high mentality and deeply rooted
individualism such as man, in whom the instinct of love and family are
so strong, led by the inevitable force of circumstances to live in the
society of his fellows, we can easily understand that certain
individuals of a higher mentality than the others will endeavor to
dominate the weaker and less intelligent, and exploit them for their
own profit and that of their family.

Analogous tendencies are seen in certain animals. Among the bees the
old workers appropriate the produce of the work of others. Certain
ants practice a form of slavery, based, it is true on instinct, in
stealing the pupae of weaker species which, after hatching, become the
servants of the idle robbers.

In incomplete animal societies, such as those of the ruminants,
certain monkeys, etc., the old males, sometimes also the more
courageous females (cows, for example) direct the herd and become
recognized as chiefs by the others. But in these cases the personal
property of objects or even living beings takes no part, because the
animals have not yet learned its value.

Other animals living isolated show the first tendencies toward
personal property; for example, the nest where they hoard their
provisions, while others, such as the ants, bees, wasps, etc., have
the sentiment of collective property well developed. For instance, a
swarm of ants regards plants with grubs as its property, and defends
them in consequence.

As soon as he has attained a primitive degree of culture, man
comprehends that the possession, not only of land and the produce of
work, but also the persons of other men, may profit him; and this
leads to slave
