John Searle

Analytic · North America · 1932 to 2025

American philosopher who held that the brain causes the mind, yet that a computer following rules does not understand.

What it is

John Searle (1932 to 2025) was an American philosopher who worked on language and on the mind. Born in Denver, he studied at the University of Wisconsin and at Oxford, where he held a Rhodes scholarship, and he then taught at the University of California, Berkeley.

He is known for his account of speech acts, the things people do by speaking, such as promising or ordering, and for the Chinese room, a thought experiment aimed at the claim that a computer running the right program would literally understand. He also wrote on the mind and on how societies are built.

The main ideas

Speaking is acting. Following his Oxford teacher J. L. Austin, he treated promising and other uses of speech as acts, and in Speech Acts (1969) he set out the conditions that make such an act what it is.
Direction of fit. He used the idea of a direction of fit between words and the world, along with the point of an act and the state of mind it expresses, to sort speech acts into kinds.
Indirect acts. A speaker can perform one kind of speech act by means of performing another.
The Background. He used this name for the abilities and capacities people have that are not themselves states of mind about anything, yet let them take words and acts in a fitting way.
The Chinese room. Imagine someone who does not know Chinese, shut in a room with a manual that tells them how to answer Chinese messages. The answers could pass for a native speaker, yet the person understands nothing. Searle took this to show that manipulating symbols is not enough for understanding, and he used it against what he called strong AI.
Consciousness from the brain. He held that consciousness is a real, first-person experience that is caused by the brain. He called this biological naturalism, and it led him to say that making a conscious being would mean copying whatever the brain does to cause consciousness, not just running a program.

What it looks like in practice

Picture someone who asks a voice assistant for the time and gets a correct, polite answer. Searle would ask two separate questions: whether the words were used correctly, and whether anything in the machine understands them. He would say the first can be settled by watching the output and the second cannot. This is an illustration of his line of questioning, not a passage from his writing.

Books and moments

Speech Acts (1969) analyses promising and other acts of speech and the rules that govern them.
The Chinese room (1980) was his argument against strong AI.
His later writing took up intentionality, consciousness and social reality.

Questions and criticism

Does the room understand? One reply holds that the person does not understand but the whole system of person, manual and room might. Critics including Douglas Hofstadter and Daniel Dennett have pressed replies of their own.
What would count as a conscious machine? Searle ties consciousness to the physical processes of the brain. It is fair to ask what exactly must be copied for a machine to qualify, and how anyone could tell.
A documented wrongdoing. In 2019 the University of California withdrew his emeritus status after finding that he had broken its rules on sexual harassment and retaliation. The argument itself can be judged on its merits, apart from this.
