American philosopher who defended the language of thought hypothesis — thought occurs in an innate mentalese — and the modularity thesis, arguing that the mind is organized into informationally encapsulated domain-specific modules.

The Language of Thought: thinking is computation over mental representations with syntactic structure and semantic content — mentalese is innate and universal. Modularity of Mind: the mind contains encapsulated input modules (vision, language processing) plus central cognition. Informational semantics: mental representations get their content from nomic dependencies on distal causes.
