This volume examines the nature and significance of the reflexive aspect of natural language, its capacity to represent its own structure and use through reported speech and explicit statements about language-use (metapragmatics). It adopts a truly interdisciplinary approach. Part I contains papers outlining the volume's theoretical scope. Parts II and III contain anthropological case studies which show the formal devices behind reflexive usage in a variety of different languages and how they function in cultural life. Finally, Part IV shows the importance of understanding reflexive language in many other areas of the humanities and social sciences, including philosophy, psychology, religious studies, sociology and literary studies. Many of the contributors are senior scholars of international reputation: all are innovative researchers. Cumulatively their work here represents a critique of those researchers in the humanities and social sciences who fail to take language seriously both in the lives of those they study and in their own research practices.

John Lucy uses original, empirical data to examine the Sapir-Whorf linguistic relativity hypothesis: the proposal that the grammar of the particular language that we speak affects the way we think about reality. The author compares the grammar of American English with that of the Yucatec Maya, an indigenous language spoken in Southeastern Mexico, focusing on differences in the number marking patterns of the two languages. He then identifies distinctive patterns of thought relating to these differences by means of a systematic assessment of memory and classification preferences among speakers of both languages.

Language Diversity and Thought examines the Sapir-Whorf linguistic relativity hypothesis: the proposal that the grammar of the particular language that we speak affects the way we think about reality. Adopting a historical approach, the book reviews the various lines of empirical inquiry that arose in America in response to the ideas of anthropologists Edward Sapir and Benjamin L. Whorf. John Lucy asks why there has been so little fruitful empirical research on this problem and what lessons can be learned from past work. He then proposes a new, more adequate approach to future empirical research. A companion volume, Grammatical Categories and Cognition, illustrates the proposed approach with an original case study. The study compares the grammar of American English with that of Yucatec Maya, an indigenous language spoken in southeastern Mexico, and then identifies distinctive patterns of thinking related to the differences between the two languages.
