Using Language: The Structures of Speech Acts

In a pioneer study of how language is actually used, Dr. Kearns combines the rigor of formal logic with a detailed analysis of natural language patterns. Through this double focus, he develops artificial languages that are syntactically more similar to the spoken word than first-order language itself. Numerous diagrams illustrate the evolution of these artificial languages, which represent a significant contribution to both the fields of linguistics and logic.
The book begins by delineating a theory of the structures of intentional acts and then applies this to the special case of linguistic acts. Given an understanding of the meanings of component expressions, we can use our knowledge of linguistic structure to determine the meaning of a complex expression. An innovative discussion of semantics is subdivided into theories of three "semantic dimensions": representational meaning, inferential meaning, and truth conditions. Drawing upon these analyses the speech act theory of this book purposes that the meaning of a sentence (sentential act) is to be explained wholly in terms of the meanings of component expressions (acts) and the structure of the sentence.
