the Behring Strait, the Kadiaks of Alaska, the Tinnehs in the interior of British North America; Letourneau compiled reports of the same fact in regard to the Chippeway Indians, the Coocoos in Chile, the Caribeans, the Carens in Indo-China, not to mention the tales of ancient Greeks and Romans about the Parthians, Persians, Scythians, Huns and so forth. Before incest was invented (and it is an invention, a really valuable one indeed), sexual intercourse between parents and children could not be any more repulsive than between other persons belonging to different generations, which takes place even in our day among the most narrow-minded nations without causing any horror. Even old "maids" of more than sixty years sometimes, if they are rich enough, marry young men of about thirty. Eliminating from the primeval forms of the family known to us those conceptions of incest—conceptions totally different from ours and often enough in direct contradiction with them—we arrive at a form of sexual intercourse that can only be designated as unrestricted. Unrestricted in the sense that the barriers drawn later on by custom did not yet exist. This in no way necessarily implies for practical purposes an injudicious pell-mell intercourse. The separate existence of pairs for a limited time is not out of the question, and even comprises the majority of cases in the group marriage of our days. And if the latest repudiator of such a primeval state, Westermarck, designates as marriage every case, where both sexes remain mated until the birth of the offspring, then this is equivalent to saying that this kind of marriage may well exist during a stage of unrestricted intercourse without contradicting license, i. e., absence of barriers drawn by custom for sexual intercourse. Westermarck bases himself on the opinion that "license includes the suppression of individual affections" so that "prostitution is its most genuine form." To me it rather seems that any understanding of primeval conditions is impossible as long as we look at them through brothel spectacles. We shall return to this point in the group marriage.
According to Morgan, the following forms developed from this primeval state at an apparently early stage:
