More than any linguist, Benjamin Lee Whorf has become associated with what he called the "linguistic relativity principle". Studying Native American languages, he attempted to account for the ways in which grammatical systems and language-use differences affected perception. Whorf also examined how a scientific account of the world differed from a religious account, which led him to study the original languages of religious scripture and to write several anti-evolutionist pamphlets. Whorf's opinions regarding the nature of the relation between language and thought remain under contention. Critics such as Lenneberg, Black and Pinker attribute to Whorf a strong linguistic determinism, while Lucy, Silverstein and Levinson point to Whorf's explicit rejections of determinism, and where he contends that translation and commensuration is possible.
