In this paper, I argue for a modified version of what Devitt (2006) calls the Representational Thesis (RT). According to RT, syntactic rules or principles are psychologically real, in the sense that they are represented in the mind/brain of every linguistically competent speaker/hearer. I present a range of behavioral and neurophysiological evidence for the claim that the human sentence processing mechanism constructs mental representations of the syntactic properties of linguistic stimuli. I then survey a range of psychologically plausible computational models (...) of comprehension and show that they are all committed to RT. I go on to sketch a framework for thinking about the nature of the representations involved in sentence processing. My claim is that these are best characterized not as propositional attitudes but, rather, as subpersonal states whose representational properties are determined by their functional role. Finally, I distinguish between explicit and implicit representations and argue that the latter can be drawn on as data by the algorithms that constitute our sentence processing routines. I conclude that skepticism concerning the psychological reality of grammars cannot be sustained. (shrink)

I examine two arguments for the existence of demonstrative concepts—one due to Chuard (2006) and another due to Brewer (1999). I point out some important difficulties in each. I hope to show that much more work must be done to legitimize positing demonstrative concepts.

In “How We Know Our Own Minds: The Relationship Between Mindreading and Metacognition,” Peter Carruthers argues for a view according to which first-person awareness of one’s own propositional attitudes is always interpretive, though one’s awareness of “sensory-imagistic” states is not. In this commentary, I criticize Carruthers’ way of drawing the distinction between sensory states and propositional attitudes. Furthermore, I argue for the superiority of a view, which I derive from Wilfrid Sellars, according to which all self-ascriptions of mental states are, (...) at bottom, interpretive—i.e., the outputs of an inferential process that consists in applying a folk-psychological theory to oneself.
