Definition and stakes

Portrait of William Graham Sumner William Graham Sumner,  Folkways

“ Incest taboo strongest in the strongest groups. We shall see, in the cases to be presented, that incest has a wider definition and a stricter compulsion in great tribes, and in prosperity or wealth, than in small groups and poverty. The definiteness of this taboo, and the strictness with which it is enforced, seem to be correlative with the energy of the tribal discipline in general and the vigor of the collective life of the group. Wives can be got abroad, either by capture or contract, only by those who command respect for their power or who use power. ”

514. Incest in ethnography. Martius says of the tribes on the upper Amazon, in general, that incest in all grades is frequent amongst them. In the more southern regions the taboo is stricter and better observed. Amongst the former it is shameful for a man to marry his sister or his brother's daughter. The usages are the more strict the larger the tribe is. In small isolated groups it frequently happens that a man lives with his sister.

“ From what source, in the final analysis, springs the dread of incest which must be recognized as the root of exogamy? It evidently does not suffice to appeal to an instinctive aversion against sexual intercourse with blood relatives, that is to say, to the fact of incest dread, in order to explain the dread of incest, if social experience shows that, in spite of this instinct, incest is not a rare occurrence even in our society, and if the experience of history can acquaint us with cases in which incestuous marriage of privileged persons was made the rule. ”
