This commentary seeks to supplement the case Quilty-Dunn et al. make for the psychological reality of languages-of-thought (LoTs) in two ways. First, it focuses on the reduced physical demands which LoT architectures often make compared to alternative architectures. Second, it embeds LoT research within a broader framework that can be leveraged to understand the evolution of LoTs.

The idea that cognition makes use of one or more “languages of thought” remains central to much cognitive-scientific and philosophical theorizing. And yet, virtually no attention has been paid to the question of how a language of thought might evolve in the first place. In this article, I take some steps towards addressing this issue. With the aid of the so-called Sender–Receiver framework, I elucidate a family of distinctions and processes which enable us to see how languages of thought might (...) evolve via a series of small, incremental changes. While much work doubtlessly remains to be done in this area, I hope to at least show that there need be nothing mysterious about the existence of languages of thought on evolutionary grounds.

Grice’s analysis of human communication has proven to be highly influential among many philosophers and cognitive scientists, both past and present. At the same time, it has long been recognized that his analysis faces some difficult objections. In particular, a number of theorists have objected to the account Grice provides of the mental states and processes of those engaged in communication. For these theorists, communication as conceived of by Grice has seemed too mentally demanding and complex to be a good (...) general model of human communication. In this article, I consider this challenge afresh from the perspective of Dan Dennett’s intentional stance theory. More specifically, I consider some recent remarks Dennett has made in this area, seeking to pin down and clarify his view. I then argue that while Dennett’s thinking is on the right track, his view stands in need of both a substantive adjustment and more positive detail. I seek to provide such improvements here. Finally, I consider some of the implications of this improved Dennettian account of Gricean communication for how great ape and human communication are related. (shrink)

While the term “metacognition” is sometimes used to refer to any form of thinking about thinking, in cognitive psychology, it is typically reserved for thinking about one’s own thinking, as opposed to thinking about others’ thinking. How metacognition in this more specific sense relates to other-directed mindreading is one of the main theoretical issues debated in the literature. This article considers the idea that we make use of the same or a largely similar package of resources in conceptually interpreting our (...) own mind as we do in interpreting others’. I assume that a capacity for other-directed mindreading is minimally shared with our great-ape relatives, but I argue that the architecture of this system had to be substantially modified before it could efficiently and adaptively be turned inwards on one’s own mind. I contend that an important piece of the overall evolutionary explanation here likely concerns selection pressures arising from the domain of conversational interaction. Specifically, drawing on work carried out in the human interaction studies tradition (e.g., conversation analysis), I argue that the smooth to-and-fro of conversational interaction can be seen to heavily depend on metacommunicative capacities, which, in turn, are underpinned by metacognitive capacities. I conclude with a thumbnail sketch of an evolutionary account of the emergence of these metacognitive capacities in the human line. Their appearance and spread – whether via genes, cultural learning, or more likely, some combination of the two – helps to explain the transition from great-ape communication to human conversation.

In this paper, I discuss two influential pictures of communication and the relation between them. One picture holds that successful communication requires identity of content: The speaker has a belief that she expresses with her utterance, and the hearer acquires a belief with the same content by understanding the utterance. The second picture was proposed by Lewis in his classic work Convention and then refined in “Languages and Language.” It sees communication as coordination among speakers—a technical notion that Lewis draws (...) from game theory. Samuel Cumming has recently provided an elegant and insightful synthesis of the two pictures, arguing that Lewisian coordination among speakers is in fact a form of content identity. In this paper, my negative goal is to argue against Cumming’s attempt to construe coordination as content identity, showing that it yields incorrect predictions about certain cases of successful communication. My positive goal is to show how we can avoid Cumming’s problematic interpretation of coordination and still do justice to the relevant data within a coordination-based framework. (shrink)

This paper explores the significance of intelligent social behavior among non-human animals for philosophical theories of communication. Using the alarm call system of vervet monkeys as a case study, I argue that interpersonal communication (or what I call “minded communication”) can and does take place in the absence of the production and recognition of communicative intentions. More generally, I argue that evolutionary theory provides good reasons for maintaining that minded communication is both temporally and explanatorily prior to the use of (...) communicative intentions. After developing these negative points about the place of communicative intentions in detail, I provide a novel alternative account according to which minded communication is characterized in terms of patterns of action and response that function to coordinate the representational mental states of agents. I show that an account which centers on patterns of representational coordination of this sort is well suited to capture the theoretical roles associated with minded communication and that it does so in a way that provides a good fit with comparative facts about the presence of minded communication among non-human animals.
