Causal theories of mental content attempt to explain how thoughts can be about things. They attempt to explain how one can think about, for example, dogs. These theories begin with the idea that there are mental representations and that thoughts are meaningful in virtue of a causal connection between a mental representation and some part of the world that is represented. In other words, the point of departure for these theories is that thoughts of dogs are about dogs because dogs (...) cause the mental representations of dogs. (shrink)

Some mental states are about themselves. Nothing is a cause of itself. So some mental states are not about their causes; they are about things distinct from their causes. If this argument is sound, it spells trouble for causal theories of mental content—the precise sort of trouble depending on the precise sort of causal theory. This paper shows that the argument is sound (§§1-3), and then spells out the trouble (§4).

hc thcsis of this paper is that thc causal themy of mental cantent (hcrcaftcr CT) is incompatible with an clcmcntary fact of pcrccptual psychology, namely, that thc detection 0f distal propcrtics generally requires thc mediation of a “the- 0ry.” I shall call this fact thc nontransducibility of distal properties (hcrcaftcr NTDP). The argument proceeds in two stages. Thc burden of stage 0nc is that, taken together, CT and thc language 0f thought hypothesis (hcrcaftcr LOT) arc incompatible with NTDP. The burden (...) of stage two is that acceptance of CT rcquircs acceptance of LOT as well. It follows that CT is incompatiblc with NTDP. I organize things in this way in part bccausc it makcs the argument casicr t0 understand, and in part bccausc thc stage-two thcsis—that CT cntails LOT—has somc independcnt interest and is thcrcforc worth separating from thc rcst 0f thc argument. 1. STAGE ONE; THE CONJUNCTION OF CT AND LOT Is INCOMPATIBLE WITH THE NONTRANSDUCIBILITY OF DISTAL PROPERTIES Let us begin by clarifying some tcrms. By LOT, I mean the hypothesis that thc human schcmc 0f mental rcprcscmation satisfies the following conditions: (1) It has a finite number of semantically primitive expressions individuatcd syntactically.

Robert Cummins argues that any causal theory of mental content (CT) founders on an established fact of human psychology: that theory mediates sensory detection. He concludes,.

I demonstrate that locking on, a key notion in Jerry Fodor's most recent theory of content, supplemented informational atomism (SIA), is cashed out in terms of asymmetric dependence, the central notion in his earlier theory of content. I use this result to argue that SIA is incompatible with the language of thought hypothesis because the constraints on the causal relations into which symbols can enter imposed by the theory of content preclude the causal relations needed between symbols for them to (...) serve as the elements of the medium of thought.
