Overview
Proposed by John Searle in 1980, the argument imagines a person in a room who doesn't know Chinese but has a book of rules for responding to Chinese characters. To someone outside, the person seems to understand Chinese, but they are actually just following symbols.
Key Point
Searle argues that 'syntax is not semantics'—simply manipulating symbols (as computers do) is not the same as having a mind or true understanding (intentionality).
Relevance to LLMs
This argument is frequently cited in debates about whether models like GPT-4 actually 'know' anything or are just 'stochastic parrots' matching patterns.
