Wilhelm Max Wundt,
Elements of Folk Psychology
“ Though the causes of polyandry are thus entirely different from those of polygyny, it does not at all follow that these forms of marriage are mutually exclusive. On the contrary, they may very well exist side by side, as, indeed, they actually do in many places. But how, then, is so-called group-marriage related to these two forms? It is obviously nothing but a combination of polyandry and polygyny. In fact, whenever a group of men marries a group of women, these two forms of polygamy are both involved. Every man has several wives, and every wife has several husbands. ”
