Language, Thought, and Reality: Selected Writings of Benjamin Lee Whorf (1956) is a landmark collection of essays that defines the field of ethnolinguistics and introduces the Sapir-Whorf Hypothesis (the principle of linguistic relativity). Edited by John B. Carroll, this volume brings together the most influential works of Benjamin Lee Whorf, a pioneering linguist who argued that the structure of the language we speak fundamentally shapes our perception of the world.
