The Modularity of Mind | Jerry A. Fodor

Summary of: The Modularity of Mind
By: Jerry A. Fodor


Embark on a journey to demystify the complexities of the human mind with ‘The Modularity of Mind’ by Jerry A. Fodor. The book delves deep into faculty psychology, a field that explores how different psychological mechanisms interact and contribute to the human mind’s function. Unravel the differences between the modularity thesis and the general notion of psychological faculties. Navigating between Neocartesian and Empiricist explanations, we will investigate the concept of mental structures and the intriguing ideas of horizontal and vertical faculties. Gain insights into cognitive systems, their modularity, and the very limits of human knowledge.

Understanding Faculty Psychology

Faculty psychology emphasizes that different mental faculties work together to form the mind. Perception, learning, and language all interact via various psychological mechanisms. Unlike associationist theories like behaviorism, this approach suggests that mental abilities are innate. The book explores the modularity thesis, its impact on cognitive systems, and which processes are modular. It also contemplates the limits of human knowledge.

Understanding Mental Structure

This summarized book section talks about the different explanations presented by cognitive science regarding human mental structure. There are two main ones; the Neocartesian and the Empiricist. Neocartesians believe that the structure of the mind is similar to that of knowledge, while Empiricists disagree and argue against the notion of innate mentality. Chomsky’s writing is based on the Neocartesian tradition, which suggests that people possess innate information and utilize it to develop linguistic abilities. Mental structures are compared to physical structures, such as the heart or visual system. However, unlike physical structures, linguistic development requires cognition, which may be innate. Besides, deductive structure is part of mental structure since human beings innately understand certain things about language and employ some form of deduction to arrive at behavior. Other mental structures, such as memory, may not include deductive structures. Lastly, mental structures also have a functional architecture, where faculties are distinguished by their propositional content and functions or effects.

Exploring the Mind’s Mechanisms

This book chapter compares the notions of horizontal and vertical faculties with regards to how the mind works. Horizontal faculties are those that operate across different content domains, such as memory and judgment. On the other hand, vertical faculties are domain-specific mechanisms that function independently from other faculties. While the idea of horizontal faculties has been around since the philosophical tradition’s origins, Franz Joseph Gall’s work introduced the concept of vertical faculties later on. Gall claimed that people use different mechanisms for different tasks, such as musical or mathematical abilities. While his argument that all horizontal faculties are fictitious may not hold weight, there is some evidence to support vertical faculties’ existence. These specific faculties have distinct neural structures, genetic determination, domain specificity, and computational autonomy. While some aspects of Gall’s theories have faced criticism, his contributions continue to be relevant in understanding the complexity of the mind.
