Following a long tradition in anthropology and linguistics, introductory textbooks typically claim that all languages are equal and have an equal potential for communication and thought. The theoretical model posed in this anthology, as articulated by contributor Angela Gilliam, similarly suggests that “all languages are equal in terms of their expressive potential” (p. 84). However, editor Arthur K. Spears and the contributors aim to situate linguistic relativity within a framework of political, social, economic, and (most centrally) racial inequalities. The key theme of the collection is the centrality of politics, particularly what Spears terms “racial hierarchies of oppression” (13), in the study of language and linguistic diversity. As the contributors provide detailed historical, economic, and social frameworks for their studies, they demonstrate a claim made by Dell Hymes more than two decades ago that linguistic relativity “omits the costs and the constitutive role of social factors” (1973: 64). Thus, this edited volume challenges the tradition of claiming linguistic equality and demonstrates sociolinguistic inequality; it is part of a theoretical movement in this direction also exemplified by Zentella 1995, Hymes 1996, Schieffelin, Woolard & Kroskrity 1998, and Kroskrity 2000.
