[172] LIPPERT, _Geschichte der Familie_, 218, 219, who distinguishes between the "Alt- und Gesamtfamilie" and the modern "Sonderfamilie." [173] Of course, only a bare outline of the author's able treatise is here given. See especially _Die mensch. Familie_, 176 ff. ("Exogamie und Clanbildung"), 197 ff. ("Entwicklungsbedingungen und Wesen des Matriarchats"), 227 ff. ("Die Bündnissformen im Matriarchat"), 274 ff. ("Der Frauenraub und seine Folgen"), 347 ff. ("Ausbildung des Patriarchats"), 529 ff. ("Die Altfamilie"). The influence of economic forces on the evolution of matrimonial and family institutions is especially emphasized by Grosse. Restricting his examination to the conditions which lie within actual "historical or ethnological experience," he seeks to demonstrate that the "various forms of the family correspond to the various forms of economy (_Wirthschaft_);" that "in its essential features the character of each particular form of the family may be explained by the form of economy in which it is rooted." For the sake of clearer analysis the peoples known to history or ethnology are arranged, not in three, but in five groups according to the leading types of industrial life. These are the lower and upper hunters, the pastoral peoples, and the lower and upper cultivators of the soil.[174] But, like Kohler, Lippert, and Hellwald,[175] the author rejects the popular theory adhered to by Hildebrand, that the chase, herding, and agriculture are three successive stages of progress through which all the races of mankind have necessarily passed. For, as a matter of fact, some pastoral peoples, and even some hunters, like the Eskimo, are more advanced in culture than various peoples who are chiefly dependent upon agriculture; and some tillers of the soil, as Hildebrand concedes, may never have passed through the pastoral stage.[176] On the other hand, Grosse distinguishes two forms of the family: the individual family (_Sonderfamilie_), or the community of parents and children living in a lasting and exclusive marriage relation, and the great-family (_Grossfamilie_), which comprises, not merely parents and children, but all descendants with their families, so far as they are not separated from it by marriage or otherwise. Examples of the "great-family" are afforded by the Romans and the Chinese; while the "individual family" is practically the only form known wherever western European culture prevails. In each form of the family either the maternal or the paternal succession (_Mutterfolge_ or _Vaterfolge_) may exist; but succession must not be confused with the matriarchate or with the patriarchate, each involving the idea of authority; although paternal succession usually implies paternal power, while succession in the female line does not necessarily carry with it the supremacy of the mother.
