[28] It is well known that sociological studies upon the subject of marriage date from 1861, when Bachofen’s “Das Mutterrecht” came out. Since then a very extensive literature on the subject has appeared, without by any means exhausting the subject. (See Dr. Steinmetz, “Die neueren Forschungen zur Geschichte der menschlichen Familie”, “Zeitschr. für Sozialwissenschaft,” 1899.)

[Note to the American Edition: The literature upon the origin and evolution of marriage and the family has recently been considerably increased. The following books seem to us to be the most important: H. Schurtz, “Altersklassen und Männerbünde”; M. Weber, “Ehefrau und Mutter in der Rechtsentwicklung”; A. Vierkandt, “Das Problem der Familien- und Stammesorganisation der Naturvölker”; E. Westermarck, “Ursprung und Entwicklung der Moralbegriffe”, II; F. Müller-Lyer, “Formen der Ehe”, “Die Familie”, and “Phasen der Liebe”; H. Cunow, “Zur Urgeschichte der Ehe und Familie.”] [↑]

[29] Westermarck (in his “History of Human Marriage”, pp. 51–133) has led the opposition to the promiscuity theory. It is also combated by Starcke in his “Die primitive Familie” and by Grosse in his “Die Formen der Familie und die Formen der Wirthschaft” (pp. 41–45). For a résumé of the arguments for and against see Dr. C. J. Wynaendts Francken, “De Evolutie van het huwelijk” (pp. 57–65). [↑]

[32] The following discussion is based upon material drawn from Grosse (op. cit.), and from H. Cunow (“Die ökonomischen Grundlagen der Mutterherrschaft” (“Neue Zeit”, 1897–98). [↑]

[35] Westermarck believes that there is an innate aversion to sexual relationships between persons who have lived together from childhood; and that the sexual aversion that exists between near blood-relations is in consequence of the fact that these persons have always lived together. This instinct would thus have been acquired by natural selection, since those who did not have it would run more danger than the others of disappearing in consequence of the injurious effects of such unions. (Op. cit., chaps. xiv and xv.) Cunow on the other hand makes the point that there cannot be an innate aversion between persons who have been raised together, for marriages between such persons do take place, and are not thought at all immoral or contrary to nature.
