"After the Spaniards settled the Southwest, the Navajo began another burst of cultural borrowing—or, more actually, stealing. Spanish ranches and villages were so depleted of horses—not to mention sheep—that by 1775 the Spaniards had to send to Europe for 1,500 additional horses. After the Pueblo Rebellion against the Spaniards was put down in 1692, many Pueblo took refuge with their Navajo neighbors—and taught them how to weave blankets, a skill for which the Navajo are still noted, and to make pottery. During this time the Navajo probably absorbed many Pueblo religious and social ideas and customs as well, such as ceremonial paraphernalia and possibly the Pueblo class system."

“A human being cannot survive alone and be entirely human. It is through the nature of their social and political institutions that the differences and similarities among cultures are to be accounted for.”

“By the seventeenth century, observers had reached the firm conclusion that American Indians were in no way inferior to Whites, and many writers took special pains to salute the Noble Red Man. The Jesuit missionary Bressani... reported that the inhabitants "are hardly barbarous, save in name. ...marvelous faculty for remembering places, and for describing them to one another." ...can recall things that a White "could not rehearse without writing." Another Jesuit enthusiastically corroborates... "nearly all show more intelligence in their business, speeches, courtesies, intercourse, tricks and subtleties, than do the shrewdest citizens and merchants in France.”

“Wilhelm von Humboldt... stated that the structure of language expresses the inner life of its speakers: "Man lives with the world about him, principally, indeed exclusively, as language presents it.”

“In the far north, where humans must face the constant threat of starvation, where life is reduced to the bare essentials—it turns out that one of these essentials is art. Art seems to belong to the basic pattern of life of the Eskimo, and of the neighboring Athapaskan and Algonkian Indian bands as well.”

“The more simple the society, the more leisured its way of life.”

“What most impresses the people around the prophet is the personality change he has undergone. ...when stress reaches a certain intensity in the culture, only certain individuals feel called forth to become prophets while most do not. In any event, the prophet has emerged in a new cultural role, and his personality is liberated from the stress that called his response into being in the first place. Immune to the stress under which his brethren still suffer, he must appear to them supernatural.”
