The modularity of thought and the epidemiology of representations

This chapter defends the view that thought processes might be modular too, and argues that perceptual and linguistic decoding processes are modular, much more than on the alleged nonmodularity of thought.

Abstract

Ten years ago, Jerry Fodor published The Modularity of Mind, a book that received much well-deserved attention. His target was the then-dominant view according to which there are no important discontinuities between perceptual processes and conceptual processes. Information flows freely, "up" and "down," between these two kinds of processes, and beliefs inform perception as much as they are informed by it. Against this view, Fodor argued that perceptual processes (and also linguistic decoding) are carried out by specialized, rather rigid mechanisms. These "modules" each have their own proprietary data base, and do not draw on information produced by conceptual processes.
