"The issue Fodor writes about is central to the psychology of
perception, cognition, and action. It is the central issue for anyone
who would seriously study the neurobiology of behavior: Is the mind
organized horizontally or vertically or both, and what are the
consequences to psychology of proceeding on one assumption or the
other? This has been little analyzed and written about. Jerry Fodor
has repaired that omission and had done it brilliantly."

This study synthesizes current information from the various fields of
cognitive science in support of a new and exciting theory of mind.
Most psychologists study horizontal processes like memory and
information flow; Fodor postulates a vertical and modular
psychological organization underlying biologically coherent behaviors.
This view of mental architecture is consistent with the historical
tradition of faculty psychology while integrating a computational
approach to mental processes. One of the most notable aspects of
Fodor's work is that it articulates features not only of speculative
cognitive architectures but also of current research in artificial
"Jerry Fodor's Modularity of Mind is a beginning ...
[It] is the first major monograph in this century to explore some
variations on faculty psychology [and] is the best thing Fodor has
done since The Language of Thought, mainly because it
takes such a wide sweep and yet manages to concentrate all the
arguments upon the central issue in both neuropsychology and
