Language, Mind, and Knowledge was first published in 1975. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This is Volume VII of the Minnesota Studies in the Philosophy of Science, a series published in cooperation with the Minnesota Center for Philosophy of Science at the University of Minnesota and edited by Herbert Feigl and Grover Maxwell. Professor Maxwell is the present director of the Center. Some of the papers in this volume were presented at or grew out of a conference on the philosophy of language which was held at the Center under the direction of Professor Gunderson. Others were written independently. The aim of the book, like that of the conference, is to assemble a wide variety of approaches to issues in the philosophy of language with emphasis on the ways in which the issues involved have bearing on other matters such as linguistic theory, cognitive psychology, the philosophy of mind, and epistemology. There are twelve papers by eleven contributors: “Languages and Language” by David Lewis; “Logic and Language: An Examination of Recent Criticisms of Internationalism” by Jerrold J. Katz; “The Meaning of ‘Meaning’” by Hilary Putnam; “Reference and Context” by Charles Chastain; “Language, Thought, and Communication” by Gilbert Harman; “Knowledge of Language” by Noam Chomsky; “Language, Rules, and Complex Behavior” by Michael D. Root; “A Taxonomy of Illocutionary Acts” by John R. Searle; “On What We Know” by Zeno Vendler; “Vendler on Knowledge and Belief” by Bruce Aune; “Reply to Professor Aune” by Zeno Vendler; “Brain Writing and Mind Reading” by D.C. Dennett.
