The weakness of the Sapir-Whorf Hypothesis... the impossibility of generalizing about entire cultures and then attributing these generalizations to the language spoken ...is to leave numerous facts about culture unexplained. The great religions of the world... have flourished among diverse peoples who speak languages with sharply different grammars. ...Cultures as diverse as the Aztec Empire of Mexico and the Ute hunting bands of the Great Basin spoke very closely related tongues.

Why did transculturalization seem to operate only in one direction? Whites who had lived for a time with Indians almost never wanted to leave. But almost none of the "civilized" Indians who had been given the opportunity to savor White society chose to become a part of it. ...Nor does this problem relate solely to the American Indian. Some of the first missionaries sent to the South Seas from London, in the eighteenth century, threw away their collars and married native women.
