Language in Thought and Action is a book on semantics by Samuel Ichiye Hayakawa, based on his previous work Language in Action.

Renowned professor 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.

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 is examined.
