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of Mind and Language and Professor of the Graduate School until June 2019, when his status as professor emeritus was revoked after he was found to have engaged in sexual harassment and retaliation against a former student and employee, in violation of the university's sexual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.
