1935 – 2017
Jerry Fodor (1935–2017) was an American philosopher and cognitive scientist, widely regarded as one of the most influential figures in the philosophy of mind and cognitive science of the twentieth century. He developed the Language of Thought hypothesis—the view that mental processes operate over a system of syntactically structured mental representations—and the modularity thesis, which holds that much of cognition is carried out by specialized, informationally encapsulated input systems. His work shaped debates across philosophy of psychology, linguistics, and the foundations of cognitive science.
Developed the Language of Thought (Mentalese) hypothesis in 'The Language of Thought' (1975)
Articulated the modularity of mind thesis in 'Modularity of Mind' (1983)
Defended a Representational Theory of Mind grounded in functional role and causal-informational semantics
Argued against semantic holism and for conceptual atomism in 'Concepts' (1998) and related work
Identified the 'frame problem' and the limits of computational theories of central cognition in 'The Mind Doesn't Work That Way' (2000)
