Renowned professor and former U.S. Senator S. I. Hayakawa discusses the role of language in human life, the many functions of language, and how language--sometimes without our knowing--shapes our thinking in this engaging and highly respected book. Provocative and erudite, it examines the relationship between language and racial and religious prejudice; the nature and dangers of advertising from a linguistic point of view; and, in an additional chapter called "The Empty Eye," the content, form, and hidden message of television, from situation comedies to news coverage to political advertising.
