Jerry Fodor's argument for an innate language of thought continues to be a hurdle for researchers arguing that natural languages provide us with richer conceptual systems than our innate cognitive resources. I argue that because the logical/formal terms of natural languages are given a usetheory of meaning, unlike predicates, logical/formal terms might be learned without a mediating internal representation. In that case, our innate representational system might have less logical structure than a natural language, making it possible that we augment (...) our innate representational system and improve our ability to think by learning a natural language.

I present the symbol grounding problem in the larger context of a materialist theory of content and then present two problems for causal, teleo-functional accounts of content. This leads to a distinction between two kinds of mental representations: presentations and symbols; only the latter are cognitive. Based on Milner and Goodale’s dual route model of vision, I posit the existence of precise interfaces between cognitive systems that are activated during object recognition. Interfaces are constructed as a child learns, and is (...) taught, how to interact with its environment; hence, interface structure has a social determinant essential for symbol grounding. Symbols are encoded in the brain to exploit these interfaces, by having projections to the interfaces that are activated by what they symbolise. I conclude by situating my proposal in the context of Harnad’s (1990) solution to the symbol grounding problem and responding to three standard objections. (shrink)

Barsalou's elision of the personal and sub-personal levels tends to conceal the fact that he is, at best, providing the “specs” but not yet a model for his hypothesized perceptual symbols.

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.

This volume contains fourteen essays discussing recent issues in the philosophy of language and the philosophy of mind. The collection is arranged into three sections: one on language, one on the intersection of language and mind, and a final section on mind. The topics include the context-sensitivity of semantics, anaphora, proper names, the nature of understanding, folk psychology and the Theory of Mind, self-awareness, the structure of the human mind and the extent to which it is modular, among others.

I met Ernie in 1965 on the wrestling mats of our high school in North Bergen, New Jersey, a township on top of the plateau overlooking Hoboken and across the Hudson River from Manhattan. Hoboken then was still the Hoboken of Elia Kazan’s “On the Waterfront” (1954).1 Even though the Hudson was less than a mile across at that point, it was a wide spiritual divide. We were Jersey boys, not New Yorkers. Ernie was as ambitious as I was about (...) wrestling, and, so, after the season was over, we used to take a bus to Journal Square in Jersey City, and then walk about eight city blocks to a gym to lift weights. In those days, high schools didn’t have weight rooms; and gyms were scarce, men only, quite filthy, and entirely devoid of cardio equipment and Nautilus machines. They were all sweat, grunts, groans, and clanking iron. By 1968, on Tuesdays and Thursdays, after a grueling wrestling practice at the high school, we would take a bus to New York City (it took about a half hour to get into “the City” by bus, less if the Lincoln Tunnel was not crowded), and then a short subway ride up to the New York Athletic Club on 59th street, across from Central Park, to spend a couple of hours working out with former university wrestling stars—guys in their mid-twenties from places like Oklahoma, Nebraska, and Iowa—who were training to make the Olympic team. Even with all of this wrestling time, we were frustrated by the fact that there was nowhere to work out on Sundays. We investigated and found out that the Jersey City YMCA had a wrestling mat and was open on Sundays. We then spent our Sunday afternoons working out there, so as not to miss a day of wrestling. Wrestling was our savior: a healthy way to get out anger.2 But it wasn’t all wrestling. We did something else too: We talked. We spent many hours together introspecting out loud, and just trying to make sense of things. Ernie has mentioned in print one early topic of discussion: “We spent years trying to solve various logical conundra like how on earth the Virgin Mary could have been a virgin.... (shrink)

In "The pitfalls of heritability," a review of Edward O. Wilson’s Consilience Times Literary Supplement, Feb 12, 1999, p33], Jerry Hirsch claims to have convicted Wilson of a "confusion about genetic similarity and difference." In his book, Wilson claims that if we assume that "a mere one thousand genes out of the fifty to a hundred thousand genes in the human genome were to exist in two forms in the population," the probability of any two humans--excluding identical siblings--having the same (...) genotype is vanishingly small. Hirsch points out that a single genotype can be produced in more than one way, thus increasing the likelihood of a single genotype recurring in the human population. Hirsch’s point is fair enough as far it goes, but it does not go nearly far enough. Hirsch has failed to carry out all the relevant calculations needed to determine the probability of two humans having the same genotype. In the realm of Vast numbers ("Very much greater than ASTronomical"--Dennett, 1995, p109), increased likelihood in and of itself tells us nothing. Here, then, are some of the relevant calculations.

We offer a novel argument for one-boxing in Newcomb’s Problem. The intentional states of a rational person are psychologically coherent across time, and rational decisions are made against this backdrop. We compare this coherence constraint with a golf swing, which to be effective must include a follow-through after the ball is in flight. Decisions, like golf swings, are extended processes, and their coherence with other psychological states of a player in the Newcomb scenario links her choice with the way she (...) is predicted in a common cause structure. As a result, the standard argument for two-boxing is mistaken. (shrink)

I consider how several results from cognitive science bear on the nature of representation and how representations might be structured. Distinguishing two notions of representation, presentations, which are cases of direct sensing, and symbols, which stand in for something else, I argue that only symbols pose a philosophical problem for naturalizing content. What is required is an account of how one thing can stand in for another. Milner and Goodale’s dual route model of vision offers a model for this ‘stand-in’ (...) relation. Following this model, symbols must play a functional role of activating cognitive operations relevant to what the symbols stand in for. What emerges is an interconnected network of symbols whose tokenings are central – as opposed to modular – cognitive operations. A consequence of this view, which I call an acquired language of thought since most of the symbols humans use are the words of a natural language, is that the framework for central cognition is constructed during the acquisition of a natural language lexicon.Presentations and Symbols: What Cognition Requires of Representationalism.

Palmer=s main intuition pump, the Acolor machine, @ greatly underestimates the complexity of a system isomorphic in color experience to humans. The neuroscientific picture of this complexity makes clear that the brain actively produces our experiences by processes that science can investigate, thereby supporting functionalism and leaving no (color) room for a passive observer to witness subisomorphic experiential differences.
