1. Children under 12 years of age were excluded, as were married children.

2. A fuller description of Kahl and La Jolla can be found in Swartz 1982 a :317-318. Comparisons involving various aspects of cultural sharing among the Swahili and all four of the other groups in that earlier study are found in the 1982 paper.

3. A rather different and less satisfactory explanation for this is offered in Swartz 1982 a :323-324.

4. Since in Wallace's view, there is only very limited sharing, but social life goes on, its basis must be provided through what he called "the organization of diversity"

(1970:24). Wallace's own view about the relation between culture and social life is somewhat obscured by his taking what seems to be two different positions on the definition of "culture." First, he tells us, "culture . . . becomes not so much a superorganic entity, but policy tacitly and gradually concocted by groups of people for the furtherance of their interests, and contract, established by practice, between and among individuals to organize their strivings into mutually facilitating equivalence structures" (ibid.). Culture, as defined in this statement as a contract, obviously influences social processes. Later (ibid., 37), however, he approvingly quotes Radcliffe-Brown's remark, "To say of culture patterns that they act upon an individual . . . is as absurd as to hold a quadratic equation capable of committing a murder."
