John R. Searle (1932-2025)

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of Mind and Language and Professor of the Graduate School until June 2019, when his status as professor emeritus was revoked after he was found to have engaged in sexual harassment and retaliation against a former student and employee, in violation of the university's sexual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

Quotes

Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard. ('What else could it be?') I was amused to see that Sherrington, the great British neuroscientist, thought that the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electro-magnetic systems. Leibniz compared it to a mill, and I am told some of the ancient Greeks thought the brain functions like a catapult. At present, obviously, the metaphor is the digital computer.
