John Searle

His work ranges broadly over philosophical problems of mind and language.

Recent books include The Mystery of Consciousness (1997), Mind, Language and Society: Philosophy in the Real World (1998), Rationality in Action (2001), Mind (2004), and Liberté et Neurobiologie (2004).

He teaches philosophy of mind, philosophy of language, and philosophy of social science; recent seminars topics include consciousness, free will, and rationality.

Widely noted for his contributions to the philosophy of language, philosophy of mind and social philosophy, he began teaching at Berkeley in 1959.

He received the Jean Nicod Prize in 2000; the National Humanities Medal in 2004; and the Mind & Brain Prize in 2006.

Among his notable concepts is the "Chinese room" argument against "strong" artificial intelligence.

American philosopher John Serle has made countless contributions to contemporary thinking about consciousness, language, artificial intelligence and rationality itself.

In his early work, he focused on the nature of language and what we are conveying when we speak and how the intention behind what we intend to say can the meaning of words from context to context.

He is best known for his “Chinese Room” thought experiment, which challenges the notion of a truly intelligent artificial intelligence.

In it, he imagines a room containing an individual, who speaks only English, working with a set of English instructions to write a series of Chinese characters in order to anonymous communicate with a Chinese speaker outside the room.

If that individual follows the instructions carefully, she can effectively fool the Chinese speaker into thinking he’s talking to someone who understands his language.

Serle argues that, at the very least, the metaphor raises deep complications as to whether or not one can truly describe convincing simulations of intelligence as intelligent.

He remains of firm believer that subjective experiences are real -- even if they don’t always describe things are they really are -- and are worth thinking about in objective terms because of it.
