In this provocative book, Barwise and Perry tackle the slippery subject of "meaning," a subject that has long vexed linguists, language philosophers, and logicians. Meaning does not exist solely within words and sentences but resides largely in the situation and the attitudes brought to it by those involved. The authors present an unusually lucid treatment of important innovations in the field of natural semantics, contending that the standard view of logic (as derived from Frege, Russell, and work in mathematics and logic) is inappropriate for many of the uses to which it has been put by scholars. In Situations and Attitudes they provide the basics of a realistic model-theoretic semantics of natural language, explain the main ideas of the theory, and contrast them with those of competing theories. The authors present an unusually lucid treatment of important innovations in the field of natural semantics, contending that the standard view of logic is inappropriate for many of the uses to which it has been put by scholars. John Perry  is Emeritus Professor of Philosophy at Stanford University, where he taught from 1974 to 2008, and from the University of California, Riverside, where he taught from 2008 to 2014. He has written books and articles on semantics (including pioneering work on situation semantics, with Jon Barwise), personal identity, the philosophy of language consciousness and other philosophical topics. He is the recipient of numerous awards for teaching and research, including honorary degrees from Doane College, the University of the Basque Country, and Bochum University. He is a researcher at the Center for the Study of Language and Information (CSLI).
