There is some consensus among orthodox category theorists that the concept of adjoint functors is the most important concept contributed to mathematics by category theory. We give a heterodox treatment of adjoints using heteromorphisms that parses an adjunction into two separate parts. Then these separate parts can be recombined in a new way to define a cognate concept, the brain functor, to abstractly model the functions of perception and action of a brain. The treatment uses relatively simple category theory and (...) is focused on the interpretation and application of the mathematical concepts. (shrink)

In this paper, I argue that neuroscience not only is not complemented, but rather is positively undermined, by the substantive commitments of materialist philosophers of mind. Thus, we can have neuroscience or "neurophilosophy" but not both. Since neuroscience is a real science, to the extent that it is in tension with materialistic neurophilosophy, the latter should be abandoned and the former retained.

This paper investigates whether judgement is a discrete or continuous structural phenomenon. Drawing from the Judgemental Triad—Constructivity, Coherence, Resonance—we ask whether judgement emerges in binary (0/1) thresholds or whether it can exist along a spectrum of partial attribution. We argue that while certain epistemic and legal structures treat judgement as discrete (verdict, diagnosis, classification), the underlying resonance structure suggests a gradational process of meaning formation. Judgement, therefore, is not a switch, but a flow—a temporal intensification toward structural closure. The paper (...) proposes a model of resonance gradient as the continuum of judgeability. (shrink)

This paper investigates whether it is possible to intentionally construct a structure that is judgementally inaccessible—i.e., a form that resists or negates the conditions of the Judgemental Triad: Constructivity, Coherence, and Resonance. We examine examples from architecture, cryptography, Al black-box systems, and abstract art to assess whether such structures truly lie beyond the reach of judgement, or whether their unjudgeability is a product of strategic opacity. We argue that the creation of judgementally closed systems is structurally possible but ontologically unstable, (...) and ethically suspect. Such systems do not transcend judgement—they collapse it, and in doing so, negate their own meaning. (shrink)

This paper explores the paradoxical human tendency to seek meaning in what cannot be judged—entities, events, or concepts that lie beyond the structural limits of the Judgemental Triad. We propose that this drive arises not from ignorance or error, but from an existential structure within the resonance axis itself: a compulsive demand for return even where return is impossible. Drawing from religious belief, death, infinity, and metaphysical abstraction, we argue that the urge to judge the unjudgeable reflects a deep structural (...) commitment to preserve coherence in the face of meaning collapse. This compulsion is not an error, but a boundary behavior of the human meaning system. (shrink)

This paper proposes an enhanced model that explains continuous self-awareness by integrating a Metacognition–Self-Awareness Loop, a Global Self-Model Buffer, and a Qualia Sensory Integration Node into the existing 10-step model of judgmental philosophy. While the original model presented a comprehensive structure ranging from sensory input to the formation of social norms, it lacked a specific mechanism explaining how momentary conscious judgment (Explicit Resonance) leads to a continuous sense of self. The proposed enhanced model introduces a metacognitive loop involving self-evaluation and (...) prediction immediately following judgment, a global buffer that stores and references past judgment experiences, confidence levels, and subjective feelings (qualia), and a continuous feedback path among these components. Through this, it demonstrates that beyond the discrete Explicit Resonance stage, the combination of judgment about judgment (meta-judgment) and the mechanism for storing and re-experiencing subjective sensations makes the implementation of a continuous flow of self (the stream of "I") possible from a neurocognitive-computational perspective. This enhanced model retains the structural advantages of judgmental philosophy while providing a more in-depth explanation for the emergence and maintenance of self-awareness, thereby laying the groundwork for future empirical and computational verification.

Motivated by the urgency of making explicit “the laws of possible rational passage from one concept to another”, which Professor F. William Lawvere brought into figural salience for all to see and work on, here I present my research proposal entitled Bhāvana Adhyayanaṁ, the main objective of which is: (i) characterize the space of concepts and (ii) derive laws governing the passage between concepts based on the space of concepts.

This is a long-abandoned draft, written in 2013, of what was supposed to be a paper for an edited collection (one that, in the end, didn't come together). The paper "Group Minds and Natural Kinds" descends from it.

In the 17th century, Hobbes stated that we reason by addition and subtraction. Historians of logic note that Hobbes thought of reasoning as “a ‘species of computation’” but point out that “his writing contains in fact no attempt to work out such a project.” Though Leibniz mentions the plus/minus character of the positive and negative copulas, neither he nor Hobbes say anything about a plus/minus character of other common logical words that drive our deductive judgments, words like ‘some’, ‘all’, ‘if’, (...) and ‘and’, each of which actually turns out to have an oppositive, character that allows us, “in our silent reasoning,” to ignore its literal meaning and to reckon with it as one reckons with a plus or a minus operator in elementary algebra or arithmetic. These ‘logical constants’ of natural language figure crucially in our everyday reasoning. Because Hobbes and Leibniz did not identify them as the plus and minus words we reason with, their insight into what goes on in ‘ratiocination’ did not provide a guide for a research program that could develop a +/- logic that actually describes how we reason deductively. I will argue that such a +/- logic provides a way back from modern predicate logic—the logic of quantifiers and bound variables that is now ‘standard logic’—to an Aristotelian term logic of natural language that had been the millennial standard logic.

In cognitive psychology there appears to be a creative tension between models that use connections of a network, and models that use rules for symbol manipulation. The idea of a connectionist network goes back to McCulloch & Pitts [1943] and Hebb [1949], and finds recent revival in the `parallel distributed processing' (PDP) models that have been extensively examined in the last few years (see e.g. Rumelhart et al. [1986]). In the intervening years, however, the predominant explanations of psychology have been (...) in terms of rules for the manipulation of symbolic structures (e.g. since Newell & Simon [1963]). Because of the tension between these different approaches (see e.g. Fodor & Pylyshyn [1988]), there is great interest in the formulation of `hybrid systems' which combine connectionist components with traditional symbolic processing. I attempt below to outline the general architecture of such a hybrid system. (shrink)

A friend of my sent me the address where this paper has been posted by Adam Frank. Reading it, I realized that more than 90% of the main ideas of this paper (about the mind-brain problem, quantum mechanics (microparticles-wave relationship, Schrodinger equation, probabilities, “perceiving subject in physics”, the idea about consciousness and Nagel, etc. etc.) are UNBELIEVABLE similar to my ideas from my paper 2005 or my book 2008!!!

This is indeed an auspicious time for Cognitive Science. I stand here before you this evening as the first Chair to give a presidential address to this austere body, to place on record before you what you are to accept as the Society's official view on the new science of the mind.

Several developments for diverse scientific goals, mostly in physics and physiology, had to take place, which eventually gave us fMRI as one of the central research paradigms of contemporary cognitive neuroscience. This technique stands on solid foundations established by the physics of magnetic resonance and the physiology of hemodynamics and is complimented by computational and statistical techniques. I argue, and support using concrete examples, that these foundations give rise to a productive theory-ladenness in fMRI, which enables researchers to identify and (...) control for the types of methodological and inferential errors. Consequently, this makes it possible for researchers to represent and investigate cognitive phenomena in terms of hemodynamic data and for experimental knowledge to grow independently of large scale theories of cognition.

Episodic memory is memory for past events. It’s characteristically associated with an experience of ‘mentally replaying’ one’s experiences in the mind’s eye. This biological phenomenon has inspired the development of several ‘experience replay’ algorithms in AI. In this chapter, I ask whether experience replay algorithms might shed light on a puzzle about episodic memory’s function: what does episodic memory contribute to the cognitive systems in which it is found? I argue that experience replay algorithms can serve as idealized models of (...) episodic memory for the purposes of addressing this question. Taking the DQN algorithm as a case study, I suggest that these algorithms provide some support for mnemonic accounts, on which episodic memory’s function lies in the storage, encoding and retrieval of information. By extending and adapting experience replay algorithms, we might gain further insight into episodic memory’s operations and contributions to cognition. (shrink)

Philosophy of mind and cognitive science (e.g., Clark and Chalmers 1998; Clark 2010; Palermos 2014) have recently become increasingly receptive tothe hypothesis of extended cognition, according to which external artifacts such as our laptops and smartphones can—under appropriate circumstances—feature as material realisers of a person’s cognitive processes. We argue that, to the extent that the hypothesis of extended cognition is correct, our legal and ethical theorising and practice must be updated, by broadening our conception of personal assault so as to (...) include intentional harm towards gadgets that have been appropriately integrated. We next situate the theoretical case for extended personal assault within the context of some recent ethical and legal cases and close with some critical discussion. (shrink)

In order to investigate cognition fundamental assumptions must be made about what, in general terms, it is. In cognitive science it is usually assumed that cognition is computational and representational. There have been well known disputes over these assumptions, with rival claims that cognition is dynamical, situated and embodied. In this paper I emphasize the relations between cognition and control. I present a model of cognition that makes the claim that it is a form of high-order control, and I argue (...) that viewing cognition as high-order control could be a useful framework assumption for cognitive science. Cognition has many aspects and different concepts can emphasize different aspects of it. Computational and representational assumptions have been very productive, and dynamical and embodied assumptions have also been productive, though to a much lesser extent so far. Control, however, has received insufficient attention in cognition science. The model I propose is based on a point that few will dispute, namely that control of behavior is the ultimate function of cognition. Bringing this to the foreground can be productive by highlighting the ways in which cognition is structured in relation to this control function. If this perspective is valuable it will be because the control function has a highly structuring effect on cognition. As a result a control-based perspective will predict many features of cognition and yield a coherent, integrated picture. (shrink)

Sometimes agents sincerely profess to believe a claim and yet act inconsistently with it in some contexts. In this paper, I focus on mismatch cases in the domain of religion. I distinguish between two kinds of representations: prompts and default states. Prompts are representations that must be salient to agents in order for them to play their belief-appropriate roles, whereas default states play these roles automatically. The need for access characteristic of prompts is explained by their vehicles: prompts are realized (...) in symbolic systems or even artifacts that make them inapt for automatic regulation of inference and behavior. I argue that some mismatch cases are explained by the fact that agents often report the contents of prompts when they report their beliefs, but behavior is controlled by prompts only when they are made salient to agents. I show that a number of otherwise puzzling findings in the cognitive science of religion, concerning belief intuitiveness, are illuminated by the distinction. (shrink)

Internet trolling involves making assertions with the aim of provoking emotionally heated responses, all while pretending to be a sincere interlocutor. In this paper, I give an account of some of the epistemic and psychological dimensions of trolling, with the goal of better understanding why certain kinds of trolling can be dangerous. I first analyze how trolls eschew the epistemic norms of assertion, thus covertly violating their conversation partners’ normative expectations. Then, drawing on literature on the “explore/exploit trade-off,” I argue (...) that trolling is a kind of exploratory behaviour. Specifically, it involves exploring the consequences of violating an interlocutor’s expectation that one will follow the epistemic norms of assertion. To defend this account, I argue that it explains various facts about trolls and the kind of pleasure they get from their activities. My account provides a deeper understanding of why trolling can be dangerous: namely, it explains why certain trolling behaviours contribute to radicalizing people into extremist or hateful ideologies, as well as why online platforms where trolls run amok gradually become polluted with extreme, hateful speech.

A striking feature of the latest version of Dennett’s ‘big picture’ of the evolution of life and mind is frequent reference to ‘affordances’. An affordance is, roughly, a possibility for action for a creature in an environment. Given more than one possibility for action, a good question is: what will the creature actually do? I argue that affordances pose a problem of selection, and that a good general solution to this problem of mind-design is to implement a system of preferences.

Shadmehr and Ahmed’s book is a welcome extension of optimal foraging theory and neuroeconomics, achieved by integrating both with parameters relating to effort and rate of movement. Their most persuasive and prolific data comes from saccades, where times before and after decision are reasonably determinate. Skeletal movements are less likely to exhibit such tidy temporal organisation.

Enactivism does not have its primary philosophical roots in pragmatism: phenomenology (from Husserl to Jonas) is its first source of inspiration (with the exception of Hutto & Myin’s radical enactivism). That does not exclude the benefits of pragmatist readings of enactivism, and of enactivist readings of pragmatism. After having sketched those readings, this paper focuses on the philosophical concept of intentionality. I show that whereas enactivists endorse the idea that intentionality is a base-level property of cognition, pragmatism offer(ed) us some (...) reasons not to proceed this way. It is therefore doubtful to hold that pragmatists and enactivists would converge in the defence of a common, non-representational conception of intentionality. (shrink)

In this chapter, I juxtapose the mindshaping research program with the literature on the metaphysics of social construction. I suggest that these research programs are remarkably congenial. The practices of interest to mindshaping theorists are more or less straightforward instances of the processes that are taken to be essential to social construction. As such, a constructionist metaphysics of psychological kinds is readily available. I discuss some recent constructionist treatments of particular psychological kinds against this backdrop, before considering how the constructionist (...) outlook interacts with more orthodox viewpoints in the metaphysics of mind.

The Anatomy of Boredom offers a comprehensive examination of boredom—a ubiquitous, important, yet often misunderstood dimension of human existence. It explores boredom's elaborate history, provides a systematic presentation of the diverse literature on the subject, examines boredom's social grounds and consequences, and considers its future implications—all in the service of advancing a novel theoretical model of the workings of boredom that illuminates both boredom’s complex nature and its diverse psychological, behavioral, and social effects. Specifically, the book argues for a functional (...) theory of boredom, one that understands and individuates boredom in terms of its role in our mental, behavioral, and social existence. Boredom, the book posits, is the painful realization of suboptimal cognitive engagement, and as such, a powerful mechanism for regulating cognition and behavior. The functional articulation of boredom offers several important advantages over alternative theories of boredom: it provides a parsimonious and productive synthesis of existing research; it connects the present of boredom to its past; and finally, it permits us to extend our knowledge of boredom and to apply it to relatively unexplored domains, such as boredom’s relationship to the good life, self-regulation and self-control, poverty and capitalism, advancements in AI, animal emotions, and even aesthetics and art appreciation. The study of boredom is thus revealed to be more than just an analysis of a complex and important affective experience; it is also shown to be a perspicacious investigation into the complexities of human (and even non-human) existence.

According to the traditional approach in philosophy of memory, when all goes well, our episodic memories of particular events in our personal past constitute firsthand knowledge of the who, what, where, and what-was-it-like of those events. That is, according to the traditional approach, episodic memory is at bottom a capacity for a specific kind of knowledge. However, it’s now becoming increasingly common to treat the core epistemic dimension of episodic memories as present but non-essential, that is, as secondary to whatever (...) episodic memory exists to do. What are the grounds for this “non-epistemic turn” in the philosophy of memory? We identify three based on the empirical study of memory: “the argument from construction” appeals to evidence that the contents of episodic memory are constructed rather than stored; “the argument from error” appeals to evidence that episodic memory is highly error-prone; and, finally, “the argument from animals” appeals to evidence that some nonhuman animals can episodically remember. We argue that all three fail. (shrink)

Many recent AI systems take inspiration from biological episodic memory. Here, we ask how these ‘episodic-inspired’ AI systems might inform our understanding of biological episodic memory. We discuss work showing that these systems implement some key features of episodic memory whilst differing in important respects, and appear to enjoy behavioural advantages in the domains of strategic decision-making, fast learning, navigation, exploration and acting over temporal distance. We propose that these systems could be used to evaluate competing theories of episodic memory’s (...) operations and function. However, further work is needed to validate them as models of episodic memory and isolate the contributions of their memory systems to their behaviour. More immediately, we propose that these systems have a role to play in directing episodic memory research by highlighting novel or neglected hypotheses as pursuit-worthy. In this vein, we propose that the evidence reviewed here highlights two pursuit-worthy hypotheses about episodic memory’s function: that it plays a role in planning that is independent of future-oriented simulation, and that it is adaptive in virtue of its contributions to fast learning in novel, sparse-reward environments.

Advances in artificial intelligence (AI) create an increasing similarity between the performance of AI systems or AI-based robots and human communication. They raise the questions: whether it is possible to communicate with, understand, and even empathically perceive artificial agents; whether we should ascribe actual subjectivity and thus quasi-personal status to them beyond a certain level of simulation; what will be the impact of an increasing dissolution of the distinction between simulated and real encounters. (1) To answer these questions, the paper (...) argues that the precondition for actually understanding others consists in the implicit assumption of the subjectivity of our counterpart, which makes shared feelings and a „we-intentionality” possible. This assumption is ultimately based on the presupposition of a shared form of life, conceived here as „conviviality.” (2) The possibility that future artificial agents could meet these preconditions is refuted on the basis of embodied and enactive cognition, which links subjectivity and consciousness to the aliveness of an organism. (3) Even if subjectivity is in principle impossible for artificial agents, the distinction between simulated and real subjectivity might nevertheless become increasingly blurred. Here, possible consequences are discussed, especially using the example of virtual psychotherapy. Finally, the paper makes case for a mindful appproach to the language we use to talk about artificial systems and pleads for preventing a systematic pretense of subjectivity. (shrink)

The chapter undertakes three main tasks. The first is to review, briefly, the history of psychedelics in psychiatry, including the phenomenological and behavioural effects that first led to their being studied for therapeutic purposes. The second is to give an overview of recent research into the safety, efficacy, and therapeutic mechanisms of psychedelic-assisted psychotherapy. The third is to summarize the contributions of each of the chapters collected in this volume and show how they address philosophical issues arising from the new (...) wave of psychedelic psychiatry. The topics of these chapters cluster around three broad themes, in terms of which the volume is organized: ‘Self and Mind’, ‘Science and Psychiatry’, and ‘Ethics and Spirituality’. (shrink)

Chris Letheby, Jaipreet Mattu, and Eric Hochstein try to put an end to the “mysticism wars,” by which they mean the battle between psychedelic researchers who hold that mystical concepts ought to be employed in attempts to describe and understand psychedelic experiences and those who do not hold this. Letheby, Mattu, and Hochstein side with the former and do so on the grounds that (as they put it), “there are no good reasons to abandon mystical concepts in psychedelic science, and (...) plenty of good reasons to keep them.” At bottom, they contend that critiques of the pro-mystical-concepts view can be solved via clarifying concepts and recognizing basic (though significant) distinctions. And though they grant that mystical concepts may one day be superseded in the science of psychedelics, they maintain that this should not occur on the basis of a misplaced conceptual critique, as is (they maintain) the present-day critique of the pro-mystical-concepts view.

Occurrences of sentences that are traditionally considered category mistakes, such as ‘The red number is divisible by three’, tend to elicit a sense of oddness in assessors. In attempting to explain this oddness, existing accounts in the philosophical literature commonly claim that occurrences of such sentences are associated with a defect or phenomenology unique to the class of category mistakes. It might be thought that recent work in experimental psycholinguistics—in particular, the recording of event-related brain potentials (patterns of voltage variation (...) in the brain)—holds the potential to shed new light on this debate. I review the relevant experimental results, before arguing that they present advocates of accounts of category mistakes with a dilemma: either the uniqueness claims should be rejected, or the experimental technique in question cannot be used to test existing accounts of category mistakes in the manner that philosophers might hope.

Early in _Movements of the Mind_, Wayne Wu puts forth a foundational picture of action. On this picture, intentional action is necessarily a solution to a selection problem, a problem of choice among multiple causally possible alternatives. Forming an intention solves one selection problem; acting on that intention requires solving yet further selection problems about how to execute that intention. There are two serious issues with this picture of action. First: some intentional actions are causally necessitated. They can't be solutions (...) to selection problems. Wu's argument for this claim, which contrasts reflex with action, does not succeed in showing that action must solve a selection problem — nor that reflex does not solve such a problem. Second: the requirement to solve further selection problems while acting on an intention leads to a vicious regress that threatens the possibility of action in general. If these two issues are addressed, Wu's groundbreaking scientific approach to mental action might offer us a powerful new theory of ongoing causal control over intentional action. (shrink)

In this thesis I develop an account of how processes of social understanding are implicated in experiences of mental disorder, critiquing the lack of examination of this phenomena along the way. First, I demonstrate how disorder concepts, as developed and deployed by psychiatric institutions, have the effect of shaping the cognition of individuals with psychopathology through setting expectations. Such expectation-setting can be harmful in some cases, I argue, and can perpetuate epistemic injustices. Having developed this view, I criticise enactive accounts (...) of mental disorder for failing to consider how such terms like ‘dysfunction’ are open to interpretation and can come embedded with normative expectations. Enactive accounts consequently run the risk of perpetuating injustices in their account of the sociality of mental disorder. Similar concerns arise when we consider the attachment of enactivism to the medical model, I argue. But by adapting enactivism to consider other experiences of disorder, such as those described as ‘madness’, enactive psychiatry may genuinely provide ethical groundwork for a better conception of disordered experience. Then, I consider a further concern with a distinctly medicalised conception of mental disorder from the perspective of self-illness ambiguity, arguing that self-illness ambiguities appear to form a special class of ambiguities due to their proximity to disorder concepts which mark them as appropriate targets for therapeutic treatment. However, I argue further that we should be critical of the idea that self-illness ambiguities necessitate disambiguation, as, in cases where self and illness are demarcated, individuals may still experience distress because simply having a mental disorder can be socially alienating. The medicalised focus in self-illness ambiguity, and the explicit need from the medical perspective to disambiguate it, might then exacerbate the distress someone experiences in mental disorder. Moreover, drawing on Mad Studies, I suggest that one might not need a coherent self-narrative to live well. Because of this, one may not need to adopt a medicalised view of the self in the case of selfillness ambiguity. In order to support this analysis, I provide a phenomenological account of language and argue that the very thoughts implicated in mental disorder shape the individual’s perception of the world due to the way that language foregrounds particular aspects of our world. This demands a critical examination of the language adopted and used by both clinicians and disordered individuals. I thus conclude with some thoughts on how to approach research and developing understanding of mental disorder given that we, as people, are always implicated in this process and therefore socialisation of some kind will always be taking place.

The mainstream philosophical approach to inference, which insists on sentence-like representations and a linguistic capability, excludes non-human animals as possible agents capable of making inferences. However, an abundance of studies show that many animal species exhibit behaviors that seem to rely on some kind of reasoning. My focus here are the transitive inference tasks, which most species solve quite successfully. These findings put pressure on the mainstream views, and still lack a convincing explanation. I introduce the concept of affective representations, (...) which satisfy the semantic and structural requirements for participating in inferences. I also argue for a broader conception of inference, and show how we can apply this view to explain the results of the transitive inference studies. Finally, I suggest it is more useful to think of flexibility of thought in terms of a continuous range, rather than a dichotomy of flexible vs. inflexible. (shrink)

Living systems at any given moment enact a very constrained set of end‐directed and contextually appropriate actions that are self‐initiated from among innumerable possible alternatives. However, these constrained actions are not necessarily because the system has reduced its sensitivities to themselves and their surroundings. Quite the contrary, living systems are continually open to novel and unanticipated stimulations that require a physiology of coordination. To address these competing demands, this paper offers a novel heuristic model informed by neuroscience, systems theory, biology (...) and sign study to explain how organisms situated in diverse, complex and ever‐changing environments might draw upon the sparse order made available by ‘relevant noise’. This emergent order facilitates coordination, habituation and, ultimately, understanding of the world and its relevant affordances. Inspired by the burgeoning field of coordination dynamics and physiologist Denis Noble's concept of ‘biological relativity’, this model proposes a view of coordination on the neuronal level that is neither sequential nor stochastic, but instead implements a causal logic of phasic alignment, such that an organism's learned and inherited sets of diverse biological affinities and sympathies can be resolved into a continuous and complex range of patterns that will implement the kind of novel orientations and radical generativity required of such organisms to adaptively explore their environments and to learn from their experiences.

A review of Muhammad Ali Khalidi's Cognitive Ontology: Taxonomic Practices in the Mind-Brain Sciences.

This paper outlines three broad conceptual schemes currently in play in the sciences concerned with explaining cognitive abilities. One is the anthropocentric scheme – human cognition – that dominated our thinking about cognition until very recently. Another is the cybernetic-computational scheme – cybernetic cognition – rooted in cognitive science and flourishing in such fields as artificial intelligence, computational neuroscience, and biocybernetics. The third is an evolutionary biological scheme – phylogenetic cognition – that conceptualizes cognition in terms of the phylogeny-based approach (...) we take to all other traits of evolved organisms. It shows how these conceptions ground different research questions and methods, and how their relationship is still in flux. (shrink)

Cognitive archaeologists attempt to infer the cognitive and cultural features of past hominins and their societies from the material record. This task faces the problem of _minimum necessary competence_: as the most sophisticated thinking of ancient hominins may have been in domains that leave no archaeological signature, it is safest to assume that tool production and use reflects only the lower boundary of cognitive capacities. Cognitive archaeology involves selecting a model from the cognitive sciences and then assessing some aspect of (...) the material record through that lens. We give examples to show that background theoretical commitments in cognitive science that inform those models lead to different minimum necessary competence results. This raises an important question: what principles should guide us in selecting a model from the cognitive sciences? We outline two complementary responses to this question. The first involves using _independent_ lines of evidence to converge on a particular capacity. This can then influence model choice. The second is a broader suggestion. Theoretical diversity is a good thing in science, but is only beneficial over a limited amount of time. According to recent modelling work, one way of limiting diversity is to introduce extreme priors. We argue that having a broad spectrum of views in the philosophy of cognitive science may actually help cognitive archaeologists address the problem of minimum necessary competence. (shrink)

A familiar argument goes as follows: natural languages have infinitely many sentences, finite representation of infinite sets requires recursion; therefore any adequate account of linguistic competence will require some kind of recursive device. The first part of this paper argues that this argument is not convincing. The second part argues that it was not the original reason recursive devices were introduced into generative linguistics. The real basis for the use of recursive devices stems from a deeper philosophical concern; a grammar (...) that functions merely as a metalanguage would not be explanatorily adequate as it would merely push the problem of explaining linguistic competence back to another level. The paper traces this concern from Zellig Harris and Chomsky’s early work in generative linguistics and presents some implications. (shrink)
