Jon Barwise

He was born in Independence, Missouri, to Kenneth T. and Evelyn Barwise.

A pupil of Solomon Feferman at Stanford University, Barwise started his research in infinitary logic. After positions as assistant professor at Yale University and the University of Wisconsin, during which time his interests turned to natural language, he returned to Stanford in 1983 to direct the Center for the Study of Language and Information (CSLI). He began teaching at Indiana University in 1990. He was elected a Fellow of the American Academy of Arts and Sciences in 1999.{{cite web|title=Book of Members, 1780-2010: Chapter B|url=http://www.amacad.org/publications/BookofMembers/ChapterB.pdf|publisher=American Academy of Arts and Sciences|access-date=May 20, 2011}}

In his last year, Barwise was invited to give the 2000 Gödel Lecture; he died prior to the lecture.{{Cite journal|date=2000|title=2000 Annual Meeting of the Association for Symbolic Logic|url=https://www.jstor.org/stable/421070|journal=The Bulletin of Symbolic Logic|volume=6|issue=3|pages=361–396|doi=10.2307/421070|jstor=421070|issn=1079-8986|url-access=subscription}}

Barwise contended that, by being explicit about the context in which a proposition is made, the situation, many problems in the application of logic can be eliminated. He sought ... to understand meaning and inference within a general theory of information, one that takes us outside the realm of sentences and relations between sentences of any language, natural or formal. In particular, he claimed that such an approach resolved the liar paradox. He made use of Peter Aczel's non-well-founded set theory in understanding "vicious circles" of reasoning.

Barwise, along with his former colleague at Stanford John Etchemendy, was the author of the popular logic textbook Language, Proof and Logic. Unlike the Handbook of Mathematical Logic, which was a survey of the state of the art of mathematical logic circa 1975, and of which he was the editor, this work targeted elementary logic. The text is notable for including computer-aided homework problems, some of which provide visual representations of logical problems. During his time at Stanford, he was also the first Director of the Symbolic Systems Program, an interdepartmental degree program focusing on the relationships between cognition, language, logic, and computation. The K. Jon Barwise Award for Distinguished Contributions to the Symbolic Systems Program has been given periodically since 2001.{{Cite web |url=https://symsys.stanford.edu/viewing/htmldocument/13686 |title=K.
