The "Fodor"-FODOR fallacy bites back

TL;DR

The paper defends Pustejovsky's Generative Lexicon against Fodor and Lepore's critique, arguing that their traditional view of the lexicon is flawed and that semantic rules referencing structured representations are valid and practically useful.

Contribution

It challenges Fodor and Lepore's critique by defending the semantic framework of Pustejovsky's Generative Lexicon and clarifies its basis in established AI tradition.

Findings

Semantic rules referencing structured representations are valid.

Systems using such rules are practically effective in AI.

Fodor and Lepore's critique is based on a flawed view of the lexicon.

Abstract

The paper argues that Fodor and Lepore are misguided in their attack on Pustejovsky's Generative Lexicon, largely because their argument rests on a traditional, but implausible and discredited, view of the lexicon on which it is effectively empty of content, a view that stands in the long line of explaining word meaning (a) by ostension and then (b) explaining it by means of a vacuous symbol in a lexicon, often the word itself after typographic transmogrification. (a) and (b) both share the wrong belief that to a word must correspond a simple entity that is its meaning. I then turn to the semantic rules that Pustejovsky uses and argue first that, although they have novel features, they are in a well-established Artificial Intelligence tradition of explaining meaning by reference to structures that mention other structures assigned to words that may occur in close proximity to the first. It is argued that Fodor and Lepore's view that there cannot be such rules is without foundation, and indeed systems using such rules have proved their practical worth in computational systems. Their justification descends from line of argument, whose high points were probably Wittgenstein and Quine that meaning is not to be understood by simple links to the world, ostensive or otherwise, but by the relationship of whole cultural representational structures to each other and to the world as a whole.
