Psychosemantics: The Problem of Meaning in the Philosophy of Mind
Psychosemantics explores the relation between commonsense psychological theories and problems that are central to semantics and the philosophy of language. Building on and extending Fodor's earlier work it puts folk psychology on firm theoretical ground and rebuts externalist, holist, and naturalist threats to its position.

About the author
Jerry A. Fodor
28 books88 followersJerry Alan Fodor is an American philosopher and cognitive scientist. He is the State of New Jersey Professor of Philosophy at Rutgers University and is also the author of many works in the fields of philosophy of mind and cognitive science, in which he has laid the groundwork for the modularity of mind and the language of thought hypotheses, among other ideas. Fodor is of Jewish descent.
Fodor argues that mental states, such as beliefs and desires, are relations between individuals and mental representations. He maintains that these representations can only be correctly explained in terms of a language of thought (LOT) in the mind. Further, this language of thought itself is an actually existing thing that is codified in the brain and not just a useful explanatory tool. Fodor adheres to a species of functionalism, maintaining that thinking and other mental processes consist primarily of computations operating on the syntax of the representations that make up the language of thought.
For Fodor, significant parts of the mind, such as perceptual and linguistic processes, are structured in terms of modules, or "organs", which are defined by their causal and functional roles. These modules are relatively independent of each other and of the "central processing" part of the mind, which has a more global and less "domain specific" character. Fodor suggests that the character of these modules permits the possibility of causal relations with external objects. This, in turn, makes it possible for mental states to have contents that are about things in the world. The central processing part, on the other hand, takes care of the logical relations between the various contents and inputs and outputs.
Although Fodor originally rejected the idea that mental states must have a causal, externally determined aspect, he has in recent years devoted much of his writing and study to the philosophy of language because of this problem of the meaning and reference of mental contents. His contributions in this area include the so-called asymmetric causal theory of reference and his many arguments against semantic holism. Fodor strongly opposes reductive accounts of the mind. He argues that mental states are multiply realizable and that there is a hierarchy of explanatory levels in science such that the generalizations and laws of a higher-level theory of psychology or linguistics, for example, cannot be captured by the low-level explanations of the behavior of neurons and synapses.

Jerry Fodor's "Psychosemantics" is undeniably well written; he writes in a relatively casual tone with a moderate dose of humor, so one feels comfortable reading his book. However, one shouldn't quickly judge the book to be easy on the basis of his light demeanor. Reading his book requires a fair amount of technical knowledge in philosophy of mind and language. Moreover, the appendix section is for those who are relatively familiar with Fodor's Language of Thought hypothesis (though Fodor explains it very well without using too much jargon). This book is very important for anyone who is interested in the project of naturalizing intentionality.
While Fodor does spend a couple of chapters arguing for folk-psychology, narrow content, and against meaning holism (including Functional Role Semantics), it's really his chapter "Meaning and the World Order" that is very important. In this chapter, Fodor motivates an account of (crude) causal theory of mental content, which roughly states that all instantiations cause one to token a concept. So, an instantiation of red (i.e. red apple) causes me to token the concept RED. However, he presents a philosophical problem of naturalizing mental content known as the "disjunction problem", which is that an instantiation of cow OR horse can cause one to token the concept HORSE (In a certain condition, a cow can look like a horse). In other words, one needs a theory of mental representation that includes the phenomenon of misrepresentation. However, if one thinks that the semantic content of mental representation amounts to one event is sufficient for causing someone to token a concept, then counterfactually there is another event that likewise is sufficient for causing someone to token a same concept. In that case, event A OR event B causes a tokening of the concept 'A', so 'A' means A or B. What someone like Fodor wants is a theory that can explain how 'A' can represent A, but misrepresent B, rather than representing A or B as if both cause a correct representation 'A'. Fodor tries to present a solution known as the "asymmetric dependence" in which a causal relation between B and tokening of 'A' can only happen if there is already a causal relation between A and 'A', but not the other way around. So, a cow can cause me to see it as a 'horse' if and only if my tokening of 'horse' is already caused by a horse. If a horse had not cause me to token the concept HORSE, then a cow cannot cause me to token the concept HORSE.
Of course, there is more to Fodor's solution than I described, but for the purpose of this light review I think it's enough that the readers see one of the main purpose of Fodor's "Psychosemantics". I personally think Fodor's asymmetric dependence is a clever solution to the disjunction problem, but of course its not without problems (but then again, what philosophical solution is without blemish?). One can easily google objections against Fodor's Assymetric Dependence account to see what I mean. Nonetheless, Fodor's Psychosemantics is a must read for anyone who is interested in the philosophical project of naturalizing intentionality.

Fodor's Psychosemantics is a book that I've wanted to read for a very long time. I've read some pieces of his work, and he always writes entertainingly, humorously, with a highly engaging style. In that respect, at least, this book couldn't possibly disappoint. His philosophical rival, (or 'Auntie', as she is affectionately known), is not entirely consistent with her views, since she represents anyone that Fodor should disagree with - from content externalists such as Tyler Burge, behaviourists such as Ryle and Wittgenstein, to eliminativists like philosophical 'bad boy' Paul Churchland.
Be warned. Fodor's excellent writing style requires a certain level of familiarity with philosophical terms from epistemology, mind, science, and metaphysics. Although he does write clearly, this work, in general, wouldn't be recommended for those not fluent in such speak.
The strategy in this book is fairly straightforward - put up a straw man as your opponent, and knock him down. For myself, the clearest indication of this is in his discussion of holism. Whilst Fodor elucidates some useful distinctions that need to be borne in mind concerning holism (such as confirmation holism v. content holism), he ends the chapter by suggesting that holism about content has gained plausibility from the popularity of conceptual role semantics, which he doesn't subscribe to. (Or so he says). The chapter ends with him sneaking the bathwater in the back door, and leaving the baby outside, although I should probably leave the reader to decide the issue for themselves.
This chapter was really a turning point in the book for me. Up to this point, the first two chapters (on propositional attitude psychology, and individualism, supervenience and methodological solipsism), left me thinking - 'Here he goes!' And feeling thoroughly entertained as he espoused his dual content theory whilst tearing apart his straw men with great wit. Although I wondered if Ryle's ghost had acquired the description 'narrow content', I considered this a very interesting, relatively sophisticated idea. I admired the construction of his theory, despite lacking sympathy. But by the time we get to his third chapter, the reader is left feeling a little philosophically 'ripped off'. Wittily annihilating a caricature of a view is humorous, but ultimately unpersuasive.
All this said, I have still acquired a fascination with Fodor's work. There is no doubt that I will engage with him again in the near future, although I won't expect high quality argumentation. I will expect more humorous horse-play (and counterfactual tinkering with his own theory), more claiming to distrust modal intuitions, (despite invoking them heavily), but above all, more fun.

Semantics is for mental representations before it is for natural language. Why didn't I read that earlier.

Typical Fodor — great writing, full of wit, and he's anticipated and pulverized most posssible objections. New characters like his cat, granny, and Aunty pop up.

Pretty harsh on meaning holism, but the positive account of mental state token contents as what causes they asymmetrically depend on is pretty clever. Plus Fodor is funny sometimes.
