This paper advocates a generalized form of Expressivism, as a strategy for resolving certain metasemantic puzzles about identifying the semantic value of a context-sensitive expression in context. According to this form of Expressivism, speakers express properties of semantic parameters, and they do so in order to proffer those properties for cognitive adoption (acceptance) by their addressees. Puzzles arising from the pressure to say what a putatively context-sensitive expression refers to or denotes in contexts that do not seem to specify a (...) referent or denotation dissolve, once we appreciate that such attempts were ill-placed to begin with. Gibbard's Norm Expressivism, according to which speakers express properties of planning states or normative systems, can be regarded as a branch of this more general theory. I will however argue that Gibbard takes on commitments -- optional for the Expressivist -- that make it a bit hard to see how to distinguish his theory from a nuanced form of Subjectivism. (shrink)

According to some philosophers, a sentence's semantics can fail to constitute a complete propositional content, imposing mere constraints on such a content. Recently, Daniel Harris has begun developing a formal constraint semantics. He claims that the semantic values of sentences constrain what speakers can literally say with them—and what hearers can know about what was said. However, that claim is undermined by his conception of semantics as the study of a psychological module. I argue instead that semantic constraints should be (...) understood as properties of public languages. (shrink)

Mental representations remain the central posits of psychology after many decades of scrutiny. However, there is no consensus about the representational format(s) of biological cognition. This paper provides a survey of evidence from computational cognitive psychology, perceptual psychology, developmental psychology, comparative psychology, and social psychology, and concludes that one type of format that routinely crops up is the language-of-thought (LoT). We outline six core properties of LoTs: (i) discrete constituents; (ii) role-filler independence; (iii) predicate–argument structure; (iv) logical operators; (v) inferential (...) promiscuity; and (vi) abstract content. These properties cluster together throughout cognitive science. Bayesian computational modeling, compositional features of object perception, complex infant and animal reasoning, and automatic, intuitive cognition in adults all implicate LoT-like structures. Instead of regarding LoT as a relic of the previous century, researchers in cognitive science and philosophy-of-mind must take seriously the explanatory breadth of LoT-based architectures. We grant that the mind may harbor many formats and architectures, including iconic and associative structures as well as deep-neural-network-like architectures. However, as computational/representational approaches to the mind continue to advance, classical compositional symbolic structures – that is, LoTs – only prove more flexible and well-supported over time.

I argue that what speakers mean or express can be determined by their implicit or unconscious states, rather than explicit or conscious states. Further, on this basis, I show that the sincerity conditions for utterances can also be fixed by implicit states. This is a surprising result which goes against common assumptions about speech acts and sincerity. Roughly, I argue that the result is implied by two plausible and independent theories of the metaphysics of speaker meaning and, further, that this (...) is a robust basis on which to make an inference, with a fair degree of confidence, about the relationship between expression and implicit attitudes.

I argue that introspection recruits the same mental mechanism as that which is required for the production of ordinary speech acts. In introspection, in effect, we intentionally tell ourselves that we are in some mental state, aiming thereby to produce belief about that state in ourselves. On one popular view of speech acts, however, this is precisely what speakers do when speaking to others. On this basis, I argue that every bias discovered by social epistemology applies to introspection and other (...) forms of self-directed representation. If so, it becomes unclear in what sense social epistemology is social. (shrink)

The linguistic meaning of a word in a language is what fully competent speakers of the language have a grasp of merely in virtue of their semantic competence. The meanings of words sometimes change over time. 'Meat' used to mean 'solid food', but now means 'animal flesh eaten as food'. This type of meaning change comes with change of topic, what we’re talking about. Many people interested in conceptual engineering have claimed that there is also meaning change where topic is (...) retained. For example, they claim that the meanings of ‘fish’ and ‘pasta’ have undergone such change and that the meaning of 'marriage' would change this way after gay marriages become legal and widely accepted. In this paper I relate two sets of relatively independent literatures: mainstream philosophy of language and conceptual engineering to argue that on a plausible and widely accepted Minimalist view of meaning that is part and parcel of anti-descriptivism none of the above sorts of cases involve meaning change with topic retention. I do this by showing how to distinguish minimalism about meaning from the related theses of externalism and anti-individualism about intension and how to separate meaning from intension in a way that allows meaning and topic to remain the same despite changes in intension. The larger lesson is that much like we shouldn’t disregard the boundary between the narrowly meaning-related (“semantics”) and the more broadly communication-related (“pragmatics”), we shouldn’t disregard the boundary between the former and the more broadly thought-related, conceptual or cognitive (“cognition”).

Most theories of concepts take concepts to be structured bodies of information used in categorization and inference. This paper argues for a version of atomism, on which concepts are unstructured symbols. However, traditional Fodorian atomism is falsified by polysemy and fails to provide an account of how concepts figure in cognition. This paper argues that concepts are generative pointers, that is, unstructured symbols that point to memory locations where cognitively useful bodies of information are stored and can be deployed to (...) resolve polysemy. The notion of generative pointers allows for unresolved ambiguity in thought and provides a basis for conceptual engineering. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

We intuitively make a distinction between _lying_ and _misleading_. On the explanation of this phenomenon favored here—the _adverbial_ account—the distinction tracks whether the content and its truth-committing force are literally conveyed. On an alternative _commitment_ account, the difference between lying and misleading is predicated instead on the strength of assertoric commitment. One lies when one presents with full assertoric commitment what one believes to be false; one merely misleads when one presents it without full assertoric commitment, by merely hinting or (...) otherwise implying it. Now, as predicted by the well-supported assumption that we can also assert with pictures, the lying/misleading distinction appears to intuitively show up there too. Here I’ll explain how the debate confronting the two accounts plays out both in general and in that case, aiming to provide support for the adverbial account. (shrink)

The debate between Semantic Minimalism and Radical Contextualism is standardly characterized as concerning truth-evaluability—specifically, whether or not sentences require rich contextualization in order to express complete, truth-evaluable contents. In this paper, I examine the notion of truth-evaluability, considering which kinds of mappings it might require from worldly states of affairs to truth-values. At one end of the spectrum, an exhaustive notion would require truth-evaluable contents to map all possible states of affairs to truth-values. At the other end, a liberal notion (...) would require only that truth-evaluable contents map at least one possible state of affairs to at least one truth-value. I show that both Minimalists and Radical Contextualists rely on some intermediate, moderately strict notion of truth-evaluability, falling between these two poles. I consider four ways in which such a notion could be defined. However, I argue that each of these is ultimately implausible, giving us no reason to favour a moderately strict notion of truth-evaluability over the liberal alternative. This suggests that the debate must shift to more moderate ground; rather than concerning the in principle possibility of truth-evaluable contents, it fundamentally hinges on their explanatory value. More generally, paying close attention to the notion of truth-evaluability allows us to tease apart distinct strands in the Minimalism-Contextualism debate, and gain a better appreciation of what is at stake.

I use the psychological phenomenon of ‘attribute framing’ as a case study for exploring philosophical conceptions of semantics and the semantics-pragmatics divide. Attribute frames are pairs of sentences that use contradictory expressions to predicate the same property of an individual or object. Despite their equivalence, pairs of attribute frames have been observed to induce systematic variability in hearers’ responses. One explanation of such framing effects appeals to the distinct ‘reference point information’ conveyed by alternative frames. Although this information is taken (...) to be pragmatic, a live debate in the philosophy of language concerns the extent to which pragmatic information can really be held apart from semantics. Therefore, in this article I examine whether – and how – reference point information might be thought to intrude on the semantics of an attribute frame. I describe two ways in which the information might be considered broadly semantic, due to its being directly communicated or conventional. However, I argue that the framing data in fact support a narrower conception of semantics, and a semantics-pragmatics distinction that separates standing sentence meaning from enriched communicated meaning.

There has been debate between those who maintain that indexical expressions are not essential and those who maintain that such indexicals cannot be dispensed with without an important loss of content. This version of the essentialist view holds that thoughts must also have indexical elements. Indexical thoughts appear to be in tension with the computational theory of mind. In this case we have the following inconsistent triad: De se thoughts are essential. De se thoughts are indexical, they have a character. (...) Computations can only take the syntactic type into account, they cannot take tokens into account. If is correct, then it seems we cannot make sense of a thought which uses a character such that its referent could vary from tokening to tokening. I argue that need not cause a problem, while maintaining the CTM. I claim that computations need not be sensitive to the features of a tokened symbol in the way that character demands. This job may be performed by a non‐modular part of the mind. Resolving the triad in this way provides a reason to accept that indexicals in thought are possible. (shrink)

The dominant tradition in analytic philosophy of language views reference as paradigmatically enabled by the acquisition of words from other speakers. Via chains of transmission, these words connect the referrer to the referent. Such a picture assumes the notion of a word as a stable mapping between sound and meaning. Utterances are constructed out of such stable mappings. While this picture of language is both intuitive and historically distinguished, various trends and programs that have developed over the last few decades (...) in theoretical linguistics suggest an alternative. According to these approaches, the word, conceived of as a linguistic ‘building block’, has no special theoretical significance. While natural language systems generate structures mapping sounds onto meanings, they need not do so by composing elements which themselves specify such mappings. I shall describe some of these developments, and show how they pose a problem for traditional philosophical views of language and communication, before identifying an alternative approach to reference which does not rely on this common-sense picture of words.

What is the relationship between the claim that generics articulate psychologically primitive generalizations and the claim that they exhibit a unique form of context sensitivity? This paper maintains that the two claims are compatible. It develops and defends an overlooked form of contextualism grounded in the idiosyncrasies of System 1 thought.
