Urban argues that we cannot assume that culture is shared; we must study the question empirically. And the logical starting point for such an investigation is the discourse that actually circulates within communities--around the campfire, in ritual chanting or laments, and in speech more generally. The book contains detailed analyses of myths that were tape-recorded in their Amerindian settings, including comparisons among distinct versions collected over time, and it explores the actual mechanisms of ritual wailing, ceremonial dialogues, and other discourse phenomena.
