We propose a pluralist account of content for predictive processing systems. Our pluralism combines Millikan’s teleosemantics with existing structural resemblance accounts. The paper has two goals. First, we outline how a teleosemantic treatment of signal passing in predictive processing systems would work, and how it integrates with structural resemblance accounts. We show that the core explanatory motivations and conceptual machinery of teleosemantics and predictive processing mesh together well. Second, we argue this pluralist approach expands the range of empirical cases to (...) which the predictive processing framework might be successfully applied. This is because our pluralism is practice-oriented. A range of different notions of content are used in the cognitive sciences to explain behaviour, and some of these cases look to employ teleosemantic notions. As a result, our pluralism gives predictive processing the scope to cover these cases. (shrink)

Recent work by Stout and colleagues indicates that the neural correlates of language and Early Stone Age toolmaking overlap significantly. The aim of this paper is to add computational detail to their findings. I use an error minimisation model to outline where the information processing overlap between toolmaking and language lies. I argue that the Early Stone Age signals the emergence of complex structured representations. I then highlight a feature of my account: It allows us to understand the early evolution (...) of syntax in terms of an increase in the number and complexity of models in a cognitive system, rather than the development of new types of processing.

This paper examines the inferential framework employed by Palaeolithic cognitive archaeologists, using the work of Wynn and Coolidge as a case study. I begin by distinguishing minimal-capacity inferences from cognitive-transition inferences. Minimal-capacity inferences attempt to infer the cognitive prerequisites required for the production of a technology. Cognitive-transition inferences use transitions in technological complexity to infer transitions in cognitive evolution. I argue that cognitive archaeology has typically used cognitive-transition inferences informed by minimal-capacity inferences, and that this reflects a tendency to favour (...) cognitive explanations for transitions in technological complexity. Next I look at two alternative explanations for transitions in technological complexity: the demographic hypothesis and the environmental hypothesis. This presents us with a dilemma: either reject these alternative explanations or reject traditional cognitive-transition inferences. Rejecting the former is unappealing as there is strong evidence that demographic and environmental influences play some causal role in technological transitions. Rejecting the latter is unappealing as it means abandoning the idea that technological transitions tell us anything about transitions in hominin cognitive evolution. I finish by briefly outlining some conceptual tools from the philosophical literature that might help shed some light on the problem. (shrink)

Adam Toon defends a version of mental fictionalism: the view that our everyday talk about inner representations should be treated metaphorically, not literally. I develop a methodological distinction between two approaches to the study of the mind, which I call the philosophy-first view and the science-first view. Philosophy-first theorists are concerned with identifying and resolving philosophical problems, whereas science-first theorists are concerned with the explanation and prediction of empirical data. I argue that Toon’s case for fictionalism is distinctly philosophy-first in (...) character, and hence we are only motivated to accept his fictionalism if we likewise accept the philosophy-first view. Being explicit about these background methodological commitments has an important implication: it helps avoid unnecessary disputes. A science-first theorist may well disagree that we should be fictionalists, but that disagreement is best understood as a second-order, methodological dispute between the relative merits of the philosophy-first view and the science-first view.

Shaun Gallagher [2019] argues for a ‘non-classical’ conception of nature, which includes subjects as irreducible constituents. As such, first-person phenomenology can be naturalised and at the same time resist reduction to the third-person. In the first part of this paper, I raise three concerns for the claim that nature is irreducibly subject-involving. In the second part of the paper, I suggest that embracing a process ontology could help strengthen Gallagher’s proposal.

Cecilia Heyes recently developed a novel framework for understanding human cognitive evolution. Contrary to many traditional views, cultural evolutionary psychology argues that distinctively human cognitive traits are transmitted culturally, not biologically. In labeling these mechanisms of thought “cognitive gadgets,” Heyes draws a direct analogy with the cultural artifacts studied by archaeologists. This chapter explores how cultural evolutionary psychology can inform research in cognitive archaeology and vice versa. On the former line of thought, the chapter argues that adopting Heyes’ framework goes (...) some way to addressing the Wynn’s methodological challenge by bringing the categories of the psychological and archaeological sciences closer together. Nonetheless, deep inferential challenges remain. This chapter looks at how we can interpret the record through the lens of cognitive gadgets, using behavioral modernity as a case study. It then examines the way cognitive archaeology can inform research in cultural evolutionary psychology. Using research on the evolution of language, it argues that evidence from cognitive archaeology strengthens Heyes’ case that language is a gadget. -/- . (shrink)

How do technologies that are too complex for any one individual to produce arise and persist in human populations? Contra prevailing views focusing on social learning, Osiurak and Reynaud argue that the primary driver for cumulative technological culture is our ability for technical reasoning. Whilst sympathetic to their overall position, we argue that two specific aspects of their account are implausible: first, that technical reasoning is unique to humans; and second, that technical reasoning is a necessary condition for the production (...) of cumulative technological culture. We then present our own view, which keeps technical reasoning at the forefront but jettisons these conditions. This produces an account of cumulative technological culture that maintains an important role for technical reasoning, whilst being more evolutionarily plausible. (shrink)

Review of William B Irvine's "You: A Natural History".

This paper is an introduction to the new field of biorhetorics. Biorhetorics is an applied form of rhetoric that evolved from the study of classical rhetoric, particularly Aristotelian. The author illustrates the stages of development necessary for the creation of a species-specific rhetoric: by (1) formalising rhetoric so as to create a functional rhetoric, (2) then reducing this to a symbolic rhetoric that can be used in conjunction with the collected data of an organism’s Umwelt (including its genome) to form (...) (3) a species-specific rhetoric. The paper draws upon the latest research on bacterial and viral communication to show the possibilities of biorhetorics. In the course of discussing the nature of biorhetorics the author distinguishes it from argumentation theory and rhetoric/s of biology, and positions alongside other fields used in the life sciences such as biosemiotics, information theory, game theory, etc. (shrink)

The present article aims to introduce the field of “Zoorhetorics”, as a particular case of Biorhetorics, earlier introduced by the author in the academic world. A brief explanation will be provided of its aims, methods and models, while particular attention will be devoted to the concept of “sustainable good”, considered crucial in both the “Bio-” and “Zoorhetorics” formulations.

In this essay I shall examine the representation of aggression and its issues in the model animal, the Fruit Fly, Drosophila melanogaster. The Fruit Fly is the model animal for genetics and more recently neuroscience. On the basis of its behaviour conclusions are being drawn that will help in the development of new treatments for clinical entities like aggression and anxiety disorders—the author questions those findings and asks whether more should be done to focus on the actual biology and behaviour—the (...)

Me encontré con el pensamiento de Marc Richir en el preciso momento en el que finalizaba mi vida activa, activísima, para jubilarme, jubilosamente; abrigaba, por lo tanto, el proyecto de volver a la filosofía. Digo “volver” porque es mi primer título universitario, obtenido en Buenos Aires, donde nací, en 1931. Por razones alimentarias me dediqué enseguida a la pedagogía y a cuestiones ligadas a la psicología del conocimiento. Después de una breve incursión dogmática por los senderos de la reflexología, y (...) cansada de dar de comer a los estudiantes sonidos de campanas, tuve la oportunidad de conectarme con el Instituto de Epistemología de Jean Piaget, deslumbrada por los análisis de los problemas epistemológicos, planteados a partir de formulaciones kantianas, pero en un intento de fundamentarlas a través de la experimentación sistemática dentro del cuadro de un psicología de la inteligencia. Sus consideraciones sobre las relaciones entre estructura y génesis, genoma y fenoma, operaciones y funciones, permiten la descripción de cada comportamiento inteligente en función de sus articulaciones lógicas y de sus modalidades individuales de construcción. Adjunta a la enseñanza universitaria sobre Psicología de la inteligencia, una intensa actividad en el campo de la clínica de los problemas del aprendizaje me condujo a tornar el tema de cómo es posible comprender y aprender en el problema de cómo fuera posible no comprender ni aprender, es decir, cuáles son los obstáculos que impiden un pensamiento constructivo de conocimientos.

We challenge an argument that aims to support Aesthetic Realism by claiming, first, that common sense is realist about aesthetic judgments because it considers that aesthetic judgments can be right or wrong, and, second, that becauseAesthetic Realism comes from and accounts for “folk aesthetics,” it is the best aesthetic theory available.We empirically evaluate this argument by probing whether ordinary people with no training whatsoever in the subtle debates of aesthetic philosophy consider their aesthetic judgments as right or wrong. Having shown (...) that the results do not support the main premise of the argument, we discuss the consequences for Aesthetic Realism and address possible objections to our study. (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)

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy.

In their landmark 2010 paper, “The weirdest people in the world?”, Henrich, Heine, and Norenzayan outlined a serious methodological problem for the psychological and behavioural sciences. Most of the studies produced in the field use people from Western, Educated, Industrialised, Rich and Democratic (WEIRD) societies, yet inferences are often drawn to the species as a whole. In drawing such inferences, researchers implicitly assume that either there is little variation across human populations, or that WEIRD populations are generally representative of the (...) species. Yet neither of these assumptions is justified. In many psychological and behavioural domains, cultural variation begets cognitive variation, and WEIRD samples are recurrently shown to be outliers. In the years since the article was published, attention has focused on the implications this has for research on extant human populations. Here we extend those implications to the study of ancient _H. sapiens_, their hominin forebears, and cousin lineages. We assess a range of characteristic arguments and key studies in the cognitive archaeology literature, identifying issues stemming from the problem of sample diversity. We then look at how worrying the problem is, and consider some conditions under which inferences to ancient populations via cognitive models might be provisionally justified. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that (...) teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

Theorists of human evolution are interested in understanding major shifts in human behavioural capacities (e.g. the creation of a novel technological industry, such as the Acheulean). This task faces empirical challenges arising both from the complexity of these events and the time-depths involved. However, we also confront issues of a more philosophical nature, such as how to best think about causation and explanation. This article considers such fundamental questions from the perspective of a prominent theory of causation in the philosophy (...) of science literature, namely, the interventionist theory of causation. A signature feature of this framework is its recognition of a family of distinct types of causes. We set out several of these causal notions and show how they can contribute to explaining transitions in human behavioural complexity. We do so, first, in a preliminary way, and then in a more detailed way, taking the origins of behavioural modernity as our extended case study. We conclude by suggesting some ways in which the approach developed here might be elaborated and extended. (shrink)

Understanding the minds of past populations through their material remains presents cognitive archaeologists with a range of inferential challenges. One of these is theory selection: which cognitive models should we choose for archaeological analysis, and why? In this article, we outline three problems facing researchers performing this task, and recommend four heuristics designed to mitigate the extent of those problems: consilience, theoretical pluralism, sample diversity, and robustness. The archaeologist who selects a cognitive model that does well against these heuristics stands (...) to better epistemically licence their inference from archaeological evidence to (some aspect of) hominin cognition in the deep past.

In 'How to create a cultural species: Evaluating three proposals', Nichols, Mackey, and Moll deliver a thoughtful and detailed assessment of three recent publications on human cultural evolution [from Cecilia Heyes, Kevin Laland, and Michael Tomasello]. Of these, NMM are most critical of Heyes. In this commentary, we interrogate four of those critcisms.

On Jagiello et al.'s cultural action framework, end-goal resolvability and causal transparency make possible the transmission of complex technologies through low-fidelity cultural learning. We offer three further features of goal-directed action sequences – specificity, riskiness, and complexity – which alter the effectiveness of low-fidelity cultural learning. Incorporating these into the cultural action framework generates further novel, testable predictions for bifocal stance theory.

We have developed a formal model of certain types of riddles, and implemented it in a computer program, JAPE, which generates simple punning riddles. In order to test the model, we evaluated the behaviour of the program, by having 120 children aged eight to eleven years old rate JAPE-generated texts, human-generated texts, and non-joke texts for "jokiness" and funniness. This confirmed that JAPE's output texts are indeed jokes, and that there is no significant difference in funniness or jokiness between JAPE"s (...) most comprehensible texts and published human-generated jokes.

When evaluating competing hypotheses in archaeology, researchers frequently invoke the principle of parsimony, which states that simpler hypotheses should be preferred. However, the criteria for measuring simplicity and the rationale for labeling a hypothesis as most parsimonious often remain unclear. More broadly, the epistemic merit of parsimony and its relevance to archaeological reasoning are generally assumed but rarely clarified. This article explores how archaeologists use parsimony in ethnographic analogy and formal model selection. In the first context, it is usually uncertain (...) how simplicity should be measured or why increased simplicity raises the plausibility of an ethnographic analogy. We contend that discussions of ethnographic analogy are better characterized under inference to the best explanation, where parsimony is only one heuristic among others. In the second context, simplicity is assessed by the relative complexity, rather than the quantity, of postulates in a model. This approach to parsimony, which does track plausibility under certain conditions, helps prevent false positives in archaeological interpretation. However, it also heightens the risk of rejecting alternative, complex causes. We argue that parsimony can aid in evaluating the relative likelihood of competing models and, more importantly, serve as a guide to clarify the complex histories of archaeological phenomena.

The philosophy of cognitive paleoanthropology involves three related tasks: (1) asking what inferences might be drawn from the paleontological and archaeological records to past cognition, behavior and culture; (2) constructing synthetic accounts of the evolution of distinctive hominin capacities; (3) exploring how results from cognitive paleoanthropology might inform philosophy. We introduce some distinctive cognitive paleoanthropological inferences and discuss their epistemic standing, before considering how attention to the material records and the practice of paleoanthropology can inform and transform philosophical approaches.

Veissière et al. must sacrifice explanatory realism and precision in order to develop a unified formal model. Drawing on examples from cognitive archeology, we argue that this makes it difficult for them to derive the kinds of testable predictions that would allow them to resolve debates over the nature of human social cognition and cultural acquisition.

The use of Type Ia supernovae as distance indicators led to the discovery of the accelerating expansion of the universe a decade ago. Now that large second generation surveys have significantly increased the size and quality of the high-redshift sample, the cosmological constraints are limited by the currently available sample of ~50 cosmologically useful nearby supernovae. The Nearby Supernova Factory addresses this problem by discovering nearby supernovae and observing their spectrophotometric time development. Our data sample includes over 2400 spectra from (...) spectral timeseries of 185 supernovae. This talk presents results from a portion of this sample including a Hubble diagram and a description of some analyses using this rich dataset. (shrink)

We present measurements of Ωm and Ω Λ from a blind analysis of 21 high-redshift supemovae using a new technique for fitting the multicolor light curves of Type la supernovae, first introduced by Wang and coworkers. CMAGIC takes advantage of the remarkably simple behavior of Type la supernovae on color-magnitude diagrams and has several advantages over current techniques based on maximum magnitudes. Among these are a reduced sensitivity to host galaxy dust extinction, a shallower luminosity-width relation, and the relative simplicity (...) of the fitting procedure. This allows us to provide a cross-check of previous supernova cosmology results, despite the fact that current data sets were not observed in a manner optimized for CMAGIC. We describe the details of our novel blindness procedure, which is designed to prevent experimenter bias. The data are broadly consistent with the picture of an accelerating universe and agree with a flat universe within 1.7 σ, including systematics. We also compare the CMAGIC results directly with those of a maximum magnitude fit to the same supernovae, finding that CMAGIC favors more acceleration at the 1.6 σ level, including systematics and the correlation between the two measurements. A fit for w assuming a flat universe yields a value that is consistent with a cosmological constant within 1.2 σ. © 2006. The American Astronomical Society. All rights reserved. (shrink)

Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. Bodily sensations are typically attributed to bodily locations and appear to have features such as volume, intensity, duration, and so on, that are ordinarily attributed to physical objects or quantities. Yet these sensations are often thought to be logically private, subjective, self-intimating, and the source of incorrigible knowledge for those who have them. Hence there appear to (...) be reasons both for thinking that pains (along with other similar bodily sensations) are physical objects or conditions that we perceive in body parts, and for thinking that they are not. This apparent paradox is one of the main reasons why philosophers are especially interested in pain. One increasingly popular but still controversial way to deal with this apparent paradox is to defend a perceptual or representational view of pain, according to which feeling pain is in principle no different from undergoing other standard perceptual processes like seeing, hearing, touching, etc. But there are many who think that pains are not amenable to such a treatment. Although it was the treatment of pain as a sensory-discriminative experience that had dominated the philosophical discussions throughout most of the twentieth century, attention to pains’ affective-motivational dimension has gained prominence in recent years.

Although pain is one of the most fundamental and unique experiences we undergo in everyday life, it also constitutes one of the most enigmatic and frustrating subjects for many scientists. This book provides a detailed analysis of why this issue is grounded in the nature of pain itself. It also offers a philosophically driven solution of how we may still approach pain in a theoretically compelling and practically useful manner. Two main theses are defended: (i) Pain seems inscrutable because there (...) exists no property that is commonly shared by all types of pain and that is at the same time particular to pain, setting it apart from other bodily sensations. This applies irrespective of whether we consider the psychological dimensions, neural networks, causal relations or biological functions of pain. Consequently, it is impossible to refer to ideal far-reaching and ideal distinct generalizations on the matter of pain. (ii) Despite this challenge, by focusing on the resemblance relations that hold across pains, we can generate scientific progress in explaining, predicting and treating pain. In doing so, the book aims to provide a clear conceptual basis for interdisciplinary communication and a useful heuristic for future research. (shrink)

We suggest that pain processing has a modular architecture. We begin by motivating the (widely assumed but seldom defended) conjecture that pain processing comprises inferential mechanisms. We then note that pain exhibits a characteristic form of judgement independence. On the assumption that pain processing is inferential, we argue that its judgement independence is indicative of modular (encapsulated) mechanisms. Indeed, we go further, suggesting that it renders the modularity of pain mechanisms a default hypothesis to be embraced pending convincing counterevidence. Finally, (...) we consider what a modular pain architecture might look like, and question alleged counterevidence to our proposal. (shrink)

The paradox of pain refers to the idea that the folk concept of pain is paradoxical, treating pains as simultaneously mental states and bodily states. By taking a close look at our pain terms, this paper argues that there is no paradox of pain. The air of paradox dissolves once we recognize that pain terms are polysemous and that there are two separate but related concepts of pain rather than one.

The motivational force of pain is undeniable. But what pain commands us to do, how we might satisfy this command, and if our experience of pain is inherently linked to suffering are far murkier topics. This paper brings together empirical studies of pain reprocessing during advanced meditation, the rise of allostatic paradigms to account for biological self-regulation, and the philosophy of pain in the classical Sanskrit philosophical tradition of Pratyabhijñā Śaivism to argue that pain is an allostatic imperative to adapt (...) a part of one’s body. We theorize two components of an allostatic response, heterostatic and homeostatic, that work in tandem to address pain as an allostatic command. Homeostatic responses are error-corrective in that they seek to protect an organism by returning to a previously stable steady state. Heterostatic responses are anticipatory in that they seek to better prepare an organism to meet future challenges by proactively shifting to a new steady state. We note that an organism’s successful adaptation to its environment depends not just on error-correction, but also on anticipatory change. We theorize that a broad range of affect properly accompanies pain. We propose potential directions for empirically developing this model. We also note the possibility that this model could be extended to account for mental pain. (shrink)
