Reduction in Cognitive Science

In this essay, I argue that neurophysiological materialism - the thesis that all of our mental contents are caused by non-mental, purely physical brain states - is epistemically self-refuting, and ought to be rejected even if it cannot be otherwise disproved.

Today research on prosocial behaviour is very much shaped by the success of social neuroscience. However, some philosopher's criticise neuroscience as reductionist. The purpose of this paper is to analyse this critique. With a philosophical background in Charles Taylor's hermeneutic thesis "man as a self-interpreting animal", the paper shows that neuroscientists' attempt to describe prosocial behaviour in science through brain imaging technologies (MRI) constitute a neurochemical self that resonates a modern ‘paradigm of clarity and objectivity’ as presented by Taylor. It (...) is argued that this scientific explanation model challenges Taylor's hermeneutic self. Where human behaviour previous was mapped on a psychological level, prosocial behaviour is described in the body - the human brain - on a neurophysiological level. The author applies an autism analogy metaphor, which paradoxical shows that the neurochemical self’s emphasis on structures and observations epistemological facilitate an autistic understanding of prosocial behaviour alien to the situated and interpreted feelings of Taylor's self-understanding(s), and the logic of our everyday language.

University Abstract Philosophers have sought to improve upon the logical empiricists’ model of scientific reduction. While opportunities for integration between the cognitive and the neural sciences have increased, most philosophers, appealing to the multiple realizability of mental states and the irreducibility of consciousness, object to psychoneural reduction. New Wave reductionists offer a continuum of comparative goodness of intertheoretic mapping for assessing reductions. Their insistence on a unified view of intertheoretic relations obscures epistemically significant crossscientific relations and engenders dismissive conclusions about (...) psychology. Richer, more sensitive accounts of explanatory pluralism and mechanistic explanation in science advocate multi-level approaches in cross-scientific settings and criticize the distance of the standard philosophical objections from working scientists’ practices and discoveries. The Heuristic Identity Theory, a new, scientifically informed version of the psycho-physical identity theory, incorporates these insights, showing how multiple realizability is an argument for (not against) identities in science and why, therefore, consciousness is not irreducible.

In a recent paper, Gualtiero Piccinini and Carl Craver have argued that psychology is not distinct from neuroscience. Many have argued that Piccinini and Craver’s argument is unsuccessful. However, none of these authors have questioned the appropriateness of Piccinini and Craver’s argument for their key premise—that functional analyses are mechanism sketches. My first and main goal in this paper is to show that Piccinini and Craver offer normative considerations in support of what is a descriptive premise and to provide some (...) guidelines on how to argue for this premise. My second goal is to show that the distinctness question should be of great significance for philosophy of cognitive science. (shrink)

The traditional approach to explanation in cognitive neuroscience is realist about psychological constructs, and treats them as explanatory. On the “standard framework,” cognitive neuroscientists explain behavior as the result of the instantiation of psychological functions in brain activity. This strategy is questioned by results suggesting the distribution of function in the brain, the multifunctionality of individual parts of the brain, and the overlap in neural realization of purportedly distinct psychological constructs. One response to this in the field has been to (...) employ the tools of databasing and machine learning to attempt to find and quantify specific correlations between psychological kinds such as ‘memory’ or ‘attention’ (or sub-kinds thereof) and patterns of activity in the brain. I assess the status and prospects of these projects. I argue that current proponents of the project are vague about their aims, vis-à-vis the standard framework, sometimes suggesting substantiation of the framework, sometimes suggesting retaining the framework but revising the ontology of mental constructs, and sometimes suggesting abandonment of the framework. I argue that extant results from within the projects fail to substantiate the standard framework, and propose an alternative. On my view, psychological constructs should not be viewed as explanantia, but instead as heuristic concepts that help us uncover ways that behaviors can vary and the ways that the brain implements those distinctions. I then discuss the normative upshot of these views for databasing and brain mapping projects. (shrink)

In this Handbook entry, I review how colour similarity spaces are constructed, first for physical sources of colour and secondly for colour as it is perceptually experienced. The unique hues are features of one of the latter constructions, due initially to Hering and formalized in the Swedish Natural Colour System. I review the evidence for a physiological basis for the unique hues. Finally, I argue that Tye's realist approach to the unique hues is a mistake.

This chapter provides an overview of the basic research strategies and analytic techniques deployed in computational cognitive neuroscience. On the one hand, “top-down” strategies are used to infer, from formal characterizations of behavior and cognition, the computational properties of underlying neural mechanisms. On the other hand, “bottom-up” research strategies are used to identify neural mechanisms and to reconstruct their computational capacities. Both of these strategies rely on experimental techniques familiar from other branches of neuroscience, including functional magnetic resonance imaging, single-cell (...) recording, and electroencephalography. What sets computational cognitive neuroscience apart, however, is the explanatory role of analytic techniques from disciplines as varied as computer science, statistics, machine learning, and mathematical physics. These techniques serve to describe neural mechanisms computationally, but also to drive the process of scientific discovery by influencing which kinds of mechanisms are most likely to be identified. For this reason, understanding the nature and unique appeal of computational cognitive neuroscience requires not just an understanding of the basic research strategies that are involved, but also of the formal methods and tools that are being deployed, including those of probability theory, dynamical systems theory, and graph theory.

What are mental states? When we talk about people’s beliefs or desires, are we talking about what is happening inside their heads? If so, might cognitive science show that we are wrong? Might it turn out that mental states do not exist? Mental fictionalism offers a new approach to these longstanding questions about the mind. Its core idea is that mental states are useful fictions. When we talk about mental states, we are not formulating hypotheses about people’s inner machinery. Instead, (...) we simply talk "as if" people had certain inner states, such as beliefs or desires, in order to make sense of their behaviour. This is the first book dedicated to exploring mental fictionalism. Featuring contributions from established authors as well as up-and-coming scholars in this burgeoning field, the book reveals the exciting potential of a fictionalist approach to the mind, as well as the challenges it faces. In doing so, it offers a fresh perspective on foundational debates in the philosophy of mind, such as the nature of mental states and folk psychology, as well as hot topics in the field, such as embodied cognition and mental representation. Mental Fictionalism: Philosophical Explorations essential reading for advanced undergraduates, postgraduates and professionals alike. (shrink)

Psychometric g—a statistical factor capturing intercorrelations between scores on different IQ tests—is of theoretical interest despite being a low-fidelity model of both folk psychological intelligence and its cognitive/neural underpinnings. Psychometric g idealizes away from those aspects of cognitive/neural mechanisms that are not explanatory of the relevant variety of folk psychological intelligence, and it idealizes away from those varieties of folk psychological intelligence that are not generated by the relevant cognitive/neural substrate. In this manner, g constitutes a high-fidelity bridge model of (...) the relationship between its two targets and, thereby, helps demystify the relationship between folk and scientific psychology.

Physicalism demands an explication of what it means for something to be physical. But the most popular way of providing one—viz., characterizing the physical in terms of the postulates of a scientifically derived physical theory—is met with serious trouble. Proponents of physicalism can either appeal to current physical theory or to some future physical theory (preferably an ideal and complete one). Neither option is promising: currentism almost assuredly renders physicalism false and futurism appears to render it indeterminate or trivial. The (...) purpose of this essay is to argue that attempts to characterize the mental encounter a similar dilemma: currentism with respect to the mental is likely to be inadequate or contain falsehoods and futurism leaves too many significant questions about the nature of mentality unanswered. This new dilemma, we show, threatens both sides of the current debate surrounding the metaphysical status of the mind. (shrink)

We show that the so-called Multiple-Computations Theorem in cognitive science and philosophy of mind challenges Landauer’s Principle in physics. Since the orthodox wisdom in statistical physics is that Landauer’s Principle is implied by, or is the mechanical equivalent of, the Second Law of thermodynamics, our argument shows that the Multiple-Computations Theorem challenges the universal validity of the Second Law of thermodynamics itself. We construct two examples of computations carried out by one and the same dynamical process with respect to which (...) Landauer’s principle implies contradictory predictions concerning the entropy increase. Our two examples are based on a weak version of the Multiple-Computations Theorem, which is quite uncontroversial, and therefore they amount to a clear refutation of the universal validity of Landauer’s Principle. We consider some responses to this argument that do not attempt to single out one computation over the others, and we show that they do not work. We further consider ways out of the argument by externalist approaches supporting the computational theory of the mind who propose that the interaction of a computing system with the environment is enough to select a single computation over the others. We show on physical grounds that this approach fails too. We then reverse the direction of our challenge and formulate a dilemma for supporters of the computational theory of the mind: they must reject the causal closure of physic; or else they must accept on a priori grounds that Landauer’s Principle and the Second Law of thermodynamics are not universally valid. Finally, we present our version of a type–type mind-brain identity theory called Flat Physicalism, which is based on the paradigm case of statistical mechanics, and we show that it circumvents the challenge from Landauer’s Principle and the Multiple-Computations Theorem and does not fall prey to our dilemma.

I argue that academic psychology’s quest to achieve scientific respectability by reliance on quantification and objectification is deeply flawed. Specifically, psychological theory typically cannot support prognostication beyond the binary opposition of “effect present/effect absent”. Accordingly, the “numbers” assigned to experimental results amount to little more than affixing names (e.g., more than, less than) to the members of an ordered sequence of outcomes. This, in conjunction with the conceptual under-specification characterizing the targets of experimental inquiry, is, I contend, a primary reason (...) why psychologists find it difficult to discriminate between competing, explanations of the effects of mind on behavior. Absent well-specified theory capable of enabling precise and detailed quantitative prediction, inferring underlying mental mechanisms from experimental outcomes becomes a difficult, if not impossible, task.

The discovery of the engram, the physical substrate of memory, is a central challenge for the sciences of memory. Following the application of optogenetics to the neurobiological study of memory, scientists and philosophers claim that the engram has been found. In this paper, I evaluate the implications of applying optogenetic tools to the localization of the engram. I argue that conceptions of engram localization need to be revised to be made consistent with optogenetic studies of the engram. I distinguish between (...) challenges to vehicle and content localization. First, I consider the silent engram hypothesis. According to this hypothesis, optogenetic studies indicate that synaptic efficacy, the traditional engram-bearing vehicle, is important merely for retrieval. I argue that this interpretation rests upon a misunderstanding of accessibility. Second, I argue that optogenetic-based strategies and findings conflict with preservationist and constructivist views on memory storage. There is an enduring trace, but stored content may change over time and experience, resulting in doubt about what constitutes a single engram. (shrink)

Optogenetics and DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) are important research tools in recent neurobiology. These tools allow unprecedented control over activity in specifically targeted neurons in behaving animals. Two approaches in philosophy of neuroscience, mechanism and ruthless reductionism, provide explicit accounts of experiments and results using tools like these, but each offers a different picture about how levels of mechanisms relate. I argue here that the ruthless reductionist’s direct mind‐to‐cellular/molecular activities linkages “in a single bound” better fits (...) with both the experimental designs using these tools and some of the scientists’ own judgments about their results than does the mechanist’s “nested hierarchies of mechanisms‐within‐mechanisms.” So at least some important work in current neuroscience appears to be ruthlessly reductive. Mechanism may not correctly characterize all current work in neuroscience, despite its recent popularity. (shrink)

In 1937, John Dewey delivered a lecture to the College of Physicians in Saint Louis. His clear message was that in the practice of medicine it does not suffice for physicians to treat just the body, or to look to just the body for the mechanism of disease. Emphasizing the relational nature of organism-environment, he argued that the physician must treat the whole patient and must therefore consider the environment of the patient. It makes no sense, he suggested, to provide (...) medicine to address a problem with the patient's lungs and then to send him back into the coal mine. As he put it: "We must observe and understand internal processes and their interactions from the standpoint of their interactions with what is... (shrink)

Our understanding of folk and scientific psychology often informs the law’s conclusions regarding questions about the voluntariness of a defendant’s action. The field of psychology plays a direct role in the law’s conclusions about a defendant’s guilt, innocence, and term of incarceration. However, physical sciences such as neuroscience increasingly deny the intuitions behind psychology. This paper examines contemporary biases against the autonomy of psychology and responds with considerations that cast doubt upon the legitimacy of those biases. The upshot is that (...) if reasonable doubt is established regarding whether psychology’s role in the law should be displaced, then there is room for future work to be done with respect to the truth of psychology’s conclusions about criminal responsibility.

According to Oude Maatman (2020), our recent suggestion (Borsboom et al., 2019) that symptom networks are irreducible because they rely on folk psychological descriptions, threatens to undermine the main achievements of the network approach. In this article, we take up Oude Maatman’s challenge and develop an argument showing in what sense folk psychological concepts describe features of reality, and what it means to say that folk psychology is a causal language.

Researchers in the cognitive sciences often seek neural correlates of psychological constructs. In this paper, I argue that even when these correlates are discovered, they do not always lead to reductive outcomes. To this end, I examine the psychological construct of a critical period and briefly describe research identifying its neural correlates. Although the critical period is correlated with certain neural mechanisms, this does not imply that there is a reductionist relationship between this psychological construct and its neural correlates. Instead, (...) this case study suggests that there may be many-to-many psychological-neural mappings, not just one-to-one or even one-to-many relations between psychological kinds and types of neural mechanisms.

ABSTRACT LeDoux's pioneering work on the neurobiology of fear has played a crucial role in informing debates in the philosophy of emotion. For example, it plays a key part in Griffiths’ argument for why emotions don’t form a natural kind. Likewise, it is employed by Faucher and Tappolet to defend pro-emotion views, which claim that emotions aid reasoning. LeDoux, however, now argues that his work has been misread. He argues that using emotion terms, like ‘fear’, to describe neurocognitive data adds (...) a ‘surplus meaning’: it attributes phenomenal properties to survival circuits which they don’t possess. This paper aims to explore LeDoux's new proposal, and examine the potentially devastating consequences that ensue for the aforementioned views. I end by addressing the worry that these lessons are conditional on LeDoux's own higher-order theory of emotional consciousness being true. (shrink)

Because biologization of psychiatric constructs does not involve derivation of laws, or reduce the number of entities involved, the traditional term of ‘reduction’ should be replaced. This paper describes biologization in terms of redefinition, which involves changing the definition of terms sharing the same extension. Redefinition obtains through triangulation and calibration, that is, respectively, detection of an object from two different spots, and tweaking parameters of detection in order to optimize the picture. The unity of the different views of the (...) same object does not occur through derivation from one of them, as reduction suggests, nor does it obtain through mechanistic unity or the goal of explaining one mechanism, as the phrase ‘mosaic unity’ suggests. Instead, it depends on finding a specific angle of observation, from which linguistic consistency matches sound localization in the brain, so that all observations make sense together, just as an anamorphic picture makes clear sense only when observed from the right spot.

' ' As pessoas dizem repetidas vezes que a filosofia não progride realmente, que ainda estamos ocupados com os mesmos problemas filosóficos que os gregos.

Contanto que continue a ser um verbo ́para ser ́ que pareça como se ele funciona da mesma forma como ́para comer e beber ́, (...) contanto que ainda tenhamos os adjetivos ́idênticos ́, ́verdadeiro ́, ́falso ́, ́possível ́, contanto que continuemos a falar de um rio de tempo , de uma extensão do espaço, etc., etc., os povos manter-se-ão tropeçando sobre as mesmas dificuldades intrigantes e encontram-se olhar fixamente em algo que nenhuma explanação parece capaz de esclarecer. E o que é mais, isso satisfaz um anseio pelo transcendente, porque, na medida em que as pessoas pensam que podem ver os "limites da compreensão humana", eles acreditam, naturalmente, que eles podem ver além destes. ' ' Esta citação é de Ludwig Wittgenstein que redefiniu a filosofia de cerca de 70 anos atrás (mas a maioria das pessoas ainda têm de descobrir isso). Dennett, embora ele tenha sido um filósofo por cerca de 40 anos, é um deles. Também é curioso que tanto ele e seu antagonista principal, John Searle, estudou famoso Wittgensteinians (Searle com John Austin, Dennett com Gilbert Ryle), mas Searle mais ou menos tem o ponto e Dennett não fez, (embora ele está esticando as coisas para chamar Searle ou Ryle Wittgensteinians). Dennett é um determinista difícil (embora ele tenta esgueirar a realidade na porta dos fundos), e talvez isso seja devido a Ryle, cujo famoso livro ́O conceito de mente ́ (1949) continua a ser reimpresso. Esse livro fez um grande trabalho de exorcizando o fantasma, mas deixou a máquina. Dennett gosta de fazer os erros Wittgenstein, Ryle (e muitos outros desde) ter exposto em detalhes. Nosso uso das palavras consciência, escolha, liberdade, intenção, partícula, pensamento, determina, onda, causa, aconteceu, evento (e assim por diante infinitamente) raramente são uma fonte de confusão, Mas assim que deixamos a vida normal e entrar filosofia (e qualquer discussão separada do ambiente em que a linguagem evoluiu— ou seja, o contexto exato em que as palavras tinham significado) reina o caos. Como a maioria, Dennett carece de um quadro coerente-que Searle chamou a estrutura lógica da racionalidade. Eu expandi neste consideravelmente desde que eu escrevi esta revisão e meus artigos recentes mostram em detalhe o que está errado com a aproximação de Dennett à filosofia, que uma pôde chamar o scientism em esteróides.

The aim of this paper is to refer basic philosophical approaches to the problem of musical meaning and, on the other hand, to describe some examples of the research on musical meaning found in the field of cognitive neuroscience. By looking at those two approaches together it can be seen that there is still no agreement on how musical meaning should be understood, often due to several methodological problems of which the most important seem to be the possibility of inter-theoretical (...) reduction and application of an accurate theory of explanation. I am suggesting that the application of some form of the mechanistic model of explanation might be found useful for clarifying reductionism-antireductionism dispute concerning musical meaning, and more importantly, for providing some answers for the debate in music-as-language controversy.

Consciousness and Physicalism: A Defense of a Research Program explores the nature of consciousness and its place in the world, offering a revisionist account of what it means to say that consciousness is nothing over and above the physical. By synthesizing work in the philosophy of mind, metaphysics, and philosophy of science from the last twenty years and forging a dialogue with contemporary research in the empirical sciences of the mind, Andreas Elpidorou and Guy Dove advance and defend a novel (...) formulation of physicalism. Although physicalism has been traditionally understood to be a metaphysical thesis, Elpidorou and Dove argue that there is an alternative and indeed preferable understanding of physicalism that both renders physicalism a scientifically informed explanatory project and allows us to make important progress in addressing the ontological problem of consciousness. Physicalism, Elpidorou and Dove hold, is best viewed not as a thesis (metaphysical or otherwise) but as an interdisciplinary research program that aims to compositionally explain all natural phenomena that are central to our understanding of our place in nature. Consciousness and Physicalism is replete with philosophical arguments and informed, through and through, by findings in many areas of scientific research. It advances the debate regarding the ontological status of consciousness. It will interest students and scholars in philosophy of mind, metaphysics, philosophy of cognitive science, and philosophy of science. And it will challenge both foes and friends of physicalism. -/- . (shrink)

“Dalla filosofia dell’azione alla filosofia della mente” è stato il percorso di alcuni filosofi di nazionalità varia degli anni 1980 – come Paul Churchland negli Stati Uniti o Ansgar Beckermann in Germania – che prima si sono interessati agli aspetti più teorici nella filosofia dell’azione, come il modo di funzionamento delle azioni e la loro spiegazione scientifica, e che poi, con l’arrivo e la diffusione dei personal computers e delle scienze cognitive, hanno ampliato e approfondito questo interesse di ricerca e (...) si sono dedicati alla filosofia della mente più in generale e in particolare alla spiegazione scientifica e filosofica del mentale. Sandro Nannini faceva parte di questo movimento ed è stato uno tra gli inizialmente pochi filosofi italiani che si sono occupati di questi argomenti; successivamente ne è diventato uno dei maggiori specialisti in Italia, proponendo una sua particolare versione di naturalizzazione del mentale. Subordinata agli interessi teorici è stata la sua iniziativa accademica di fondare e promuovere il primo dottorato italiano di ricerca in Scienze Cognitive. Il presente volume tratta dell’opera di Sandro Nannini in contributi che sono riflessioni più o meno specifiche sulle differenti tappe del suo percorso, affrontando temi come l’analisi dell'azione, il libero arbitrio, la discussione di Nannini di vari classici della filosofia, la tendenza del naturalismo a dissolvere la filosofia in un enciclopedismo empirico e la sfida dei qualia e della fenomenologia all’approccio naturalistico alla mente. Il volume contiene inoltre un saggio dello stesso Sandro Nannini, nel quale espone l’ultimo sviluppo della sua filosofia della mente nonché le risposte agli interventi degli altri autori: Mario De Caro, Sara Dellantonio, Rosaria Egidi, Roberta Lanfredini, Christoph Lumer, Paolo Parrini, Pietro Perconti, Claudio Pizzi, Emanuela Scribano e Giuseppe Varnier.

We support the development of non-reductive cognitive science and the naturalization of phenomenology for this purpose, and we agree that the ‘relational turn’ defended by Gallagher is a necessary step in this direction. However, we believe that certain aspects of his relational concept of nature need clarification. In particular, Gallagher does not say whether or how teleology, affect, and other value-related properties of life and mind can be naturalized within this framework. In this paper, we argue that given the phenomenological (...) standards recognized by Gallagher, his commitment to a naturalized phenomenology should entail a commitment to a naturalized concept of value; and the kind of ‘relational nature’ described by Gallagher in his paper is insufficient for this purpose.

Optogenetic techniques are described as “revolutionary” for the unprecedented causal control they allow neuroscientists to exert over neural activity in awake behaving animals. In this paper, I demonstrate by means of a case study that optogenetic techniques will only illuminate causal links between the brain and behavior to the extent that their error characteristics are known and, further, that determining these error characteristics requires comparison of optogenetic techniques with techniques having well known error characteristics and consideration of the broader neural (...) and behavioral context in which the targets of optogenetic interventions are situated.

This paper focuses on the framework for the compositional relations of properties in the sciences, or "realization relations", offered by Ken Aizawa and Carl Gillett (A&G) in a series of papers, and in particular on the analysis of "multiple realizations" they build upon it.

There is consequently (...) a real concern tha thte A&G framework for realization may not be viable. (shrink)

Courtesy of its free energy formulation, the hierarchical predictive processing theory of the brain (PTB) is often claimed to be a grand unifying theory. To test this claim, we examine a central case: activity of mesocorticolimbic dopaminergic (DA) systems. After reviewing the three most prominent hypotheses of DA activity—the anhedonia, incentive salience, and reward prediction error hypotheses—we conclude that the evidence currently vindicates explanatory pluralism. This vindication implies that the grand unifying claims of advocates of PTB are unwarranted. More generally, (...) we suggest that the form of scientific progress in the cognitive sciences is unlikely to be a single overarching grand unifying theory. (shrink)

Explanations in psychology are described as personal when they attribute psychological phenomena to the person, as when we attribute beliefs and thought processes to each other, for example. By contrast, explanations in psychology are described as subpersonal when they attribute psychological phenomena below the level of the person, as occurs when scientists describe parts of the brain as representing or evaluating, for example. The practice of subpersonal psychology raises a number of philosophical issues: whether it is acceptable to attribute psychological (...) phenomena to parts of persons, for example, and whether such attributions can yield any explanatory benefit. Even those who endorse subpersonal psychology do not necessarily agree on what this entails: there are several distinct ways of understanding the relationship between subpersonal psychology and personal psychology, which depend in part on how the ontological commitments of subpersonal explanations are understood.

I will begin by proposing a taxonomy of taxonomic positions regarding the mind–brain: localism, globalism, revisionism, and contextualism, and will go on to focus on the last position. Although some versions of contextualism have been defended by various researchers, they largely limit themselves to a version of neural contextualism: different brain regions perform different functions in different neural contexts. I will defend what I call “environmental-etiological contextualism,” according to which the psychological functions carried out by various neural regions can only (...) be identified and individuated against an environmental context or with reference to a causal history. While this idea may seem innocuous enough, it has important implications for a structure-to-function mapping in the mind and brain sciences. It entails that the same neural structures can subserve different psychological functions in different contexts, leading to crosscutting psycho-neural mappings. I will try to illustrate how this can occur with reference to recent research on episodic memory. (shrink)

This article presents and discusses one of the most prominent inferential strategies currently employed in cognitive neuropsychology, namely, reverse inference. Simply put, this is the practice of inferring, in the context of experimental tasks, the engagement of cognitive processes from locations or patterns of neural activation. This technique is notoriously controversial because, critics argue, it presupposes the problematic assumption that neural areas are functionally selective. We proceed as follows. We begin by introducing the basic structure of traditional “location-based” reverse inference (...) and discuss the influential lack of selectivity objection. Next, we rehearse various ways of responding to this challenge and provide some reasons for cautious optimism. The second part of the essay presents a more recent development: “pattern-decoding reverse inference”. This inferential strategy, we maintain, provides an even more convincing response to the lack of selectivity charge. Due to this and other methodological advantages, it is now a prominent component in the toolbox of cognitive neuropsychology. Finally, we conclude by drawing some implications for philosophy of science and philosophy of mind. (shrink)

Purpose – In the last half-century, individual sensory neurons have been bestowed with characteristics of the whole human being, such as behavior and its oft-presumed precursor, consciousness. This anthropomorphization is pervasive in the literature. It is also absurd, given what we know about neurons, and it needs to be abolished. This study aims to first understand how it happened, and hence why it persists. Design/methodology/approach – The peer-reviewed sensory-neurophysiology literature extends to hundreds (perhaps thousands) of papers. Here, more than 90 (...) mainstream papers were scrutinized. Findings – Anthropomorphization arose because single neurons were cast as “observers” who “identify”, “categorize”, “recognize”, “distinguish” or “discriminate” the stimuli, using math-based algorithms that reduce (“decode”) the stimulus-evoked spike trains to the particular stimuli inferred to elicit them. Without “decoding”, there is supposedly no perception. However, “decoding” is both unnecessary and unconfirmed. The neuronal “observer” in fact consists of the laboratory staff and the greater society that supports them. In anthropomorphization, the neuron becomes the collective. Research limitations/implications – Anthropomorphization underlies the widespread application to neurons Information Theory and Signal Detection Theory, making both approaches incorrect. Practical implications – A great deal of time, money and effort has been wasted on anthropomorphic Reductionist approaches to understanding perception and consciousness. Those resources should be diverted into more-fruitful approaches. Originality/value – A long-overdue scrutiny of sensory-neuroscience literature reveals that anthropomorphization, a form of Reductionism that involves the presumption of single-neuron consciousness, has run amok in neuroscience. Consciousness is more likely to be an emergent property of the brain. (shrink)

Flat Physicalism is a theory of through and through type reductive physicalism, understood in light of recent results in the conceptual foundations of physics. In Flat Physicalism, as in physics, so-called "high level" concepts and laws are nothing but partial descriptions of the complete states of affairs of the universe. "Flat physicalism" generalizes this idea, to form a reductive picture in which there is no room for levels, neither explanatory nor ontological. The paper explains how phenomena that seem to be (...) cases of multiple realization of special sciences kinds by physical kinds are fully explains in a reductive physicalist way. Finally, the paper exemplifies the fruitfulness of this reductive approach by showing how it can account even for a case of high-level anomaly in a deterministic universe (for example anomaly of the mental, should this turn our to be a fact about the world) - a result that may be called Anomalous Physicalism.

On Certainty was not published until 1969, 18 years after Wittgenstein’s death and has only recently begun to draw serious attention. I cannot recall a single reference to it in all of Searle and one sees whole books on W with barely a mention. There are however xlnt books on it by Stroll, Svensson, McGinn and others and parts of many other books and articles, but hands down the best is that of Daniele Moyal-Sharrock (DMS) whose 2004 volume “Understanding Wittgenstein’s (...) On Certainty” is mandatory for every educated person, and perhaps the best starting point for understanding Wittgenstein (W), psychology, philosophy and life (no I am not joking!). However (in my view) like all analysis of W, they fall far short of grasping his unique and revolutionary advance in describing behavior, suffering from the near universal tunnel vision and failing to put behavior in its broad evolutionary and contemporary scientific context, which I will attempt in skeletal form here. After doing this I will give brief comments on each article in this book of varied perspectives on W’s work. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019). Those interested in more of my writings may see ‘Talking Monkeys--Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet--Articles and Reviews 2006-2019 3rd ed (2019), The Logical Structure of Human Behavior (2019), and Suicidal Utopian Delusions in the 21st Century 4th ed (2019).

A critical analysis and evaluation of McNamara's book, "The Neuroscience of Religious Experience".

We outline a framework of multilevel neurocognitive mechanisms that incorporates representation and computation. We argue that paradigmatic explanations in cognitive neuroscience fit this framework and thus that cognitive neuroscience constitutes a revolutionary break from traditional cognitive science. Whereas traditional cognitive scientific explanations were supposed to be distinct and autonomous from mechanistic explanations, neurocognitive explanations aim to be mechanistic through and through. Neurocognitive explanations aim to integrate computational and representational functions and structures across multiple levels of organization in order to explain (...) cognition. To a large extent, practicing cognitive neuroscientists have already accepted this shift, but philosophical theory has not fully acknowledged and appreciated its significance. As a result, the explanatory framework underlying cognitive neuroscience has remained largely implicit. We explicate this framework and demonstrate its contrast with previous approaches. (shrink)

In the middle of the twentieth century, Wittgenstein warned that “the method of reducing the explanation of natural phenomena to the smallest possible number of primitive natural laws…leads…into complete darkness” (1958, p. 18). At the time, few philosophers and even fewer scientists were prepared to heed his warning. A half-century later, however, the reductive method of science—the method famously defined by Descartes, brilliantly exemplified by Newtonian physics, and long upheld as the gold standard of scientific explanation—seems to have finally lost (...) its luster. While reduction is still widely defended, in the last decades alternative views have gained credibility, to the extent that a “non-reductive science” is no longer dismissed as an oxymoron. (shrink)

I examine some of the key scientific pre-commitments of modern psychology, and argue that their adoption has the unintended consequence of rendering a purely psychological analysis of mind indistinguishable from a purely biological treatment. And, since these pre-commitments sanction an “authority of the biological”, explanation of phenomena traditionally considered the purview of psychological analysis is fully subsumed under the biological. I next evaluate the epistemic warrant of these pre-commitments and suggest there are good reasons to question their applicability to psychological (...) science. I conclude that experiential aspects of reality give us reason to remain open to the need for psychological explanation in the treatment of mind. (shrink)

This paper offers a novel view of unity in neuroscience. I set out by discussing problems with the classical account of unity-by-reduction, due to Oppenheim and Putnam. That view relies on a strong notion of levels, which has substantial problems. A more recent alternative, the mechanistic “mosaic” view due to Craver, does not have such problems. But I argue that the mosaic ideal of unity is too minimal, and we should, if possible, aspire for more. Relying on a number of (...) recent works in theoretical neuroscience—network motifs, canonical neural computations and design-principles—I then present my alternative: a “flat” view of unity, i.e. one that is not based on levels. Instead, it treats unity as attained via the identification of recurrent explanatory patterns, under which a range of neuroscientific phenomena are subsumed. I develop this view by recourse to a causal conception of explanation, and distinguish it from Kitcher’s view of explanatory unification and related ideas. Such a view of unity is suitably ambitious, I suggest, and has empirical plausibility. It is fit to serve as an appropriate working hypothesis for 21st century neuroscience. (shrink)

Recent advancements in the brain sciences have enabled researchers to determine, with increasing accuracy, patterns and locations of neural activation associated with various psychological functions. These techniques have revived a longstanding debate regarding the relation between the mind and the brain: while many authors claim that neuroscientific data can be employed to advance theories of higher cognition, others defend the so-called ‘autonomy’ of psychology. Settling this significant issue requires understanding the nature of the bridge laws used at the psycho-neural interface. (...) While these laws have been the topic of extensive discussion, such debates have mostly focused on a particular type of link: reductive laws. Reductive laws are problematic: they face notorious philosophical objections and they are too scarce to substantiate current research at the intersection of psychology and neuroscience. The aim of this article is to provide a systematic analysis of a different kind of bridge laws—associative laws—which play a central, albeit overlooked role in scientific practice. (shrink)

Since Hilary Putnam offered multiple realization as an empirical hypothesis in the 1960s, philosophical consensus has turned against the idea that mental processes are identifiable with brain processes, and multiple realization has become the keystone of the 'antireductive consensus' across philosophy of science. Thomas W. Polger and Lawrence A. Shapiro offer the first book-length investigation of multiple realization, which serves as a starting point to a series of philosophically sophisticated and empirically informed arguments that cast doubt on the generality of (...) multiple realization in the cognitive sciences. They argue that mind-brain identities have played an important role in the growth and achievements of the cognitive sciences, and suggest that there is little prospect for multiple realization in an empirically-based theory of mind. This leads Polger and Shapiro to offer an alternative framework for understanding explanations in the cognitive sciences, as well as in chemistry, biology, and other non-basic sciences. (shrink)

Recent extensions of mechanistic explanation into psychology suggest that cognitive models are only explanatory insofar as they map neatly onto, and serve as scaffolding for more detailed neural models. Filling in those neural details is what these accounts take the integration of cognitive psychology and neuroscience to mean, and they take this process to be seamless. Critics of this view have given up on cognitive models possibly explaining mechanistically in the course of arguing for cognitive models having explanatory value independent (...) of how well they align with neural mechanisms. We can have things both ways, however. The problem with seamless integration accounts is their seamlessness, not that they take cognitive models to be mechanistic. A non-componential view of mechanisms allows for cognitive and neural models that cross cut one another, and for cognitive models that don’t decompose into parts. I illustrate the inadequacy of seamless accounts of integration by contrasting how “filter” models of attention in psychology and of sodium channels in neuroscience developed; by questioning whether the mappings generated by neuroimaging subtraction studies achieve integration; and by reinterpreting the evidence for cognitive models of memory having been successfully integrated with neural models. I argue that the integrations we can realistically expect are more partial, patchy, and full of loose threads than the mosaic unity Craver describes. (shrink)

This paper offers a critique of an account of explanatory integration that claims that explanations of cognitive capacities by functional analyses and mechanistic explanations can be seamlessly integrated. It is shown that achieving such explanatory integration requires that the terms designating cognitive capacities in the two forms of explanation are stable but that experimental practice in the mind-brain sciences currently is not directed at achieving such stability. A positive proposal for changing experimental practice so as to promote such stability is (...) put forward and its implications for explanatory integration are briefly considered. (shrink)

Unlike other organs that operate continuously, such as the heart and kidneys, many of the operations of the nervous system shut down during sleep. The evolutionarily conserved unconscious state of sleep that puts animals at risk from predators indicates that it is an indispensable integral part of systems operation. A reasonable expectation is that any hypothesis for the mechanism of the nervous system functions should be able to provide an explanation for sleep. In this regard, the semblance hypothesis is examined. (...) Postsynaptic membranes are continuously being depolarized by the quantally released neurotransmitter molecules arriving from their presynaptic terminals. In this context, an incidental lateral activation of the postsynaptic membrane is expected to induce a semblance (cellular hallucination of arrival of activity from its presynaptic terminal, which forms a unit for internal sensation) of the arrival of activity from its presynaptic terminal as a systems property. This restricts induction of semblance to a context of a very high ratio of the duration of the default state of neurotransmitter-induced postsynaptic depolarization to the total duration of incidental lateral activations of the postsynaptic membrane. This requirement spans within a time-bin of a few sleep-wake cycles. Since the duration of quantal release remains maximized, the above requirement can be achieved only by ceiling the total duration of incidental lateral activations of the postsynaptic membrane, which necessitates a state of sleep.

In the light of what appear to be clear counterexamples, I argue that Jaegwon Kim’s comparative evaluation of functional reduction and reduction via necessary identities is problematic. I trace the problem to two sources: a misplaced metaphysical assumption about the explanatory role of identities and an excessively strong and narrow criterion for successful reductive explanation. Appreciating where Kim’s critique runs astray enhances our understanding of the role of necessary identities in reductive explanation.
