John Searle

John Rogers Searle (; July 31, 1932 – September 17, 2025) was an American philosopher widely noted for contributions to the philosophy of language, philosophy of mind, and social philosophy. He began teaching at the University of California, Berkeley, in 1959 and was Willis S. and Marion Slusser Professor Emeritus of the Philosophy of Mind and Language and Professor of the Graduate School until June 2019, when his status as professor emeritus was revoked after he was found to have engaged in sexual harassment and

retaliation against a former student and employee, in violation of the university's sexual harassment policies. As an undergraduate at the University of Wisconsin–Madison, Searle was secretary of "Students against Joseph McCarthy". He received all his university degrees, BA, MA, and DPhil, from the University of Oxford, where he held his first faculty positions. Later, at UC Berkeley, he became the first tenured professor to join the 1964–1965 Free Speech Movement.

In 2000, Searle received the Jean Nicod Prize; in 2004, the National Humanities Medal; and in 2006, the Mind & Brain Prize. In 2010 he was elected to the American Philosophical Society. Searle's early work on speech acts, influenced by J. L. Austin and Ludwig Wittgenstein, helped establish his reputation. Perhaps his most famous philosophical contribution is the "Chinese room" argument, which attempts to refute the thesis of "strong" artificial intelligence.
