Whilst much has been said about the implications of predictive processing for our scientific understanding of cognition, there has been comparatively little discussion of how this new paradigm fits with our everyday understanding of the mind, i.e. folk psychology. This paper aims to assess the relationship between folk psychology and predictive processing, which will first require making a distinction between two ways of understanding folk psychology: as propositional attitude psychology and as a broader folk psychological discourse. It will be argued (...) that folk psychology in this broader sense is compatible with predictive processing, despite the fact that there is an apparent incompatibility between predictive processing and a literalist interpretation of propositional attitude psychology. The distinction between these two kinds of folk psychology allows us to accept that our scientific usage of folk concepts requires revision, whilst rejecting the suggestion that we should eliminate folk psychology entirely.

The target article criticises reductionist programs in cognitive science for failing to take into account important explanatory features of the organism's physical embodiment and task environment. My aim in this commentary is to show how such features are increasingly being taken seriously by (some) researchers in cognitive neuroscience, who describe the functional activity of neural structures in terms that are context-sensitive rather than intrinsic. This approach can allow us to take seriously the concerns presented in Gallagher’s [2019] target article without (...) having to completely give up on neuroscientific explanations of human behaviour.

ABSTRACT Shagrir and Sprevak explore the apparent necessity of representation for the individuation of digits in computational systems.1 1 I will first offer a response to Sprevak’s argument that does not mention Shagrir’s original formulation, which was more complex. I then extend my initial response to cover Shagrir’s argument, thus demonstrating that it is possible to individuate digits in non-representational computing mechanisms. I also consider the implications that the non-representational individuation of digits would have for the broader theory of computing (...) mechanisms. 1 The Received View: No Computation without Representation 2 Computing Mechanisms and Functional Individuation 3 Against Computational Externalism 4 Implications for the Mechanistic Account.

While we agree in broad strokes with the characterisation of rationalization as a “useful fiction,” we think that Fiery Cushman's claim remains ambiguous in two crucial respects: the reality of beliefs and desires, that is, the fictional status of folk-psychological entities and the degree to which they should be understood as useful. Our aim is to clarify both points and explicate the rationale of rationalization.

The aim of this paper is to begin developing a version of Gualtiero Piccinini’s mechanistic account of computation that does not need to appeal to any notion of proper functions. The motivation for doing so is a general concern about the role played by proper functions in Piccinini’s account, which will be evaluated in the first part of the paper. I will then propose a potential alternative approach, where computing mechanisms are understood in terms of Carl Craver’s perspectival account of (...) mechanistic functions. According to this approach, the mechanistic function of ‘performing a computation’ can only be attributed relative to an explanatory perspective, but such attributions are nonetheless constrained by the underlying physical structure of the system in question, thus avoiding unlimited pancomputationalism. If successful, this approach would carry with it fewer controversial assumptions than Piccinini’s original account, which requires a robust understanding of proper functions. Insofar as there are outstanding concerns about the status of proper functions, this approach would therefore be more generally acceptable. (shrink)

The free energy principle, an influential framework in computational neuroscience and theoretical neurobiology, starts from the assumption that living systems ensure adaptive exchanges with their environment by minimizing the objective function of variational free energy. Following this premise, it claims to deliver a promising integration of the life sciences. In recent work, Markov blankets, one of the central constructs of the free energy principle, have been applied to resolve debates central to philosophy (such as demarcating the boundaries of the mind). (...) The aim of this paper is twofold. First, we trace the development of Markov blankets starting from their standard application in Bayesian networks, via variational inference, to their use in the literature on active inference. We then identify a persistent confusion in the literature between the formal use of Markov blankets as an epistemic tool for Bayesian inference, and their novel metaphysical use in the free energy framework to demarcate the physical boundary between an agent and its environment. Consequently, we propose to distinguish between “Pearl blankets” to refer to the original epistemic use of Markov blankets and “Friston blankets” to refer to the new metaphysical construct. Second, we use this distinction to critically assess claims resting on the application of Markov blankets to philosophical problems. We suggest that this literature would do well in differentiating between two different research programmes: “inference with a model” and “inference within a model.” Only the latter is capable of doing metaphysical work with Markov blankets, but requires additional philosophical premises and cannot be justified by an appeal to the success of the mathematical framework alone.

In this paper we will demonstrate that a computational system can meet the criteria for autonomy laid down by classical enactivism. The two criteria that we will focus on are operational closure and structural determinism, and we will show that both can be applied to a basic example of a physically instantiated Turing machine. We will also address the question of precariousness, and briefly suggest that a precarious Turing machine could be designed. Our aim in this paper is to challenge (...) the assumption that computational systems are necessarily heteronomous systems, to try and motivate in enactivism a more nuanced and less rigid conception of computational systems, and to demonstrate to computational theorists that they might find some interesting material within the enactivist tradition, despite its historical hostility towards computationalism.

The proposal that probabilistic inference and unconscious hypothesis testing are central to information processing in the brain has been steadily gaining ground in cognitive neuroscience and associated fields. One popular version of this proposal is the new theoretical framework of predictive processing or prediction error minimization, which couples unconscious hypothesis testing with the idea of ‘active inference’ and claims to offer a unified account of perception and action. Here we will consider one outstanding issue that still looms large at the (...) core of the PEM framework: the lack of a clear criterion for distinguishing conscious states from unconscious ones. In order to fulfill the promise of becoming a unifying framework for describing and modeling cognition, PEM needs to be able to differentiate between conscious and unconscious mental states or processes. We will argue that one currently popular view, that the contents of conscious experience are determined by the ‘winning hypothesis’, falls short of fully accounting for conscious experience. It ignores the possibility that some states of a system can control that system’s behavior even though they are apparently not conscious. What follows from this is that the ‘winning hypothesis’ view does not provide a complete account of the difference between conscious and unconscious states in the probabilistic brain. We show how this problem for the received view can be resolved by augmenting PEM with Daniel Dennett’s multiple drafts model of consciousness. This move is warranted by the similar roles that attention and internal competition play in both the PEM framework and the multiple drafts model. (shrink)

The past few years have seen several novel information-theoretic measures of causal emergence developed within the scientific community. In this paper I will introduce one such measure, called ‘effective information’, and describe how it is used to argue for causal emergence. In brief, the idea is that certain kinds of complex system are structured such that an intervention characterised at the macro-level will be more informative than one characterised at the micro-level, and that this constitutes a form of causal emergence. (...) Having introduced this proposal, I will then assess the extent to which it is genuinely ‘causal’ and/or ‘emergent’, and argue that it supports only an epistemic form of causal emergence that is not as exciting as it first seems.

It is generally acknowledged by proponents of ‘new mechanism’ that mechanistic explanation involves adopting a perspective, but there is less agreement on how we should understand this perspective-taking or what its implications are for practising science. This paper examines the perspectival nature of mechanistic explanation through the lens of the ‘mechanistic stance’, which falls somewhere between Dennett’s more familiar physical and design stance. We argue this approach implies three distinct and significant ways in which mechanistic explanation can be interpreted as (...) perspectival: ‘phenomenon perspectivism’, ‘pattern perspectivism’ and ‘hierarchy perspectivism’. We evaluate the strength of the perspective-dependency implied by each of these, and along the way, discuss their significance for wider debates within the new mechanism literature, such as the nature of function attribution and an ontic vs epistemic understanding of explanation.

Our aim in this paper is to explore two possible directions of interaction between normative folk psychology and decision theory. In one direction, folk psychology plays a regulative role that constrains practical decision‐making. In the other direction, decision theory provides novel tools and norms that shape folk psychology. We argue that these interactions could lead to the emergence of an iterative “decision theoretic spiral," where folk psychology influences decision‐making, decision‐making is studied by decision theory, and decision theory influences folk psychology. (...) Understanding these interactions is important both for the theoretical study of social cognition and decision theory, and also for thinking about how to implement practical interventions into real‐world decision‐making.

Mechanism realists assert the existence of mechanisms as objective structures in the world, but their exact metaphysical commitments are unclear. We introduce Local Hierarchy Realism (LHR) as a substantive and plausible form of mechanism realism. The limits of LHR reveal a deep tension between two aspects of mechanists’ explanatory strategy. Functional decomposition identifies locally relevant entities and activities, while these same entities and activities are also embedded in a nested hierarchy of levels. In principle, a functional decomposition may identify entities (...) engaging in causal interactions that crosscut the hierarchical structure of composition relations, violating the mechanist’s injunction against interlevel causation. We argue that this possibility is realized in the example of ephaptic coupling, a subsidiary process of neural computation that crosscuts the hierarchy derived from synaptic transmission. These considerations undermine the plausibility of LHR as a general view, yet LHR has the advantages that (i) its metaphysical implications are precisely stateable; (ii) the structure it identifies is not reducible to mere aggregate causation; and (iii) it clearly satisfies intuitive and informal definitions of mechanism. We conclude by assessing the prospects for a form of mechanism realism weaker than LHR that nevertheless satisfies all three of these requirements. (shrink)

Fresco and Primiero’s recent article, ‘Miscomputation’ , provides a useful framework with which to think about miscomputation, as well as an admirably broad taxonomy of different kinds of miscomputation. However, it also misconstrues the mechanistic approach to miscomputation, which I will argue should not recognise design errors as miscomputations per se. I argue that a computing mechanism, if it is functioning correctly in the physical sense, cannot miscompute on the basis of an error made by an external agent, such as (...) a programmer. This is partially acknowledged in the distinction that Fresco and Primiero make between errors of functioning and errors of design, but they go on to describe both as cases of miscomputation, which I will argue is a mistake, at least with regard to the analysis made by the mechanistic account. (shrink)

I defend Piccinini’s mechanistic account of computation against three related criticisms adapted from Sprevak’s critique of non-representational computation. I then argue that this defence highlights a major problem with what Sprevak calls the received view; namely, that representation introduces observer-relativity into our account of computation. I conclude that if we want to retain an objective account of computation, we should reject the received view.

Hobson & Friston (2014) outline a synthesis of Hobson's work on dreaming and consciousness with Friston’s work on the free energy principle and predictive coding. Whilst we are sympathetic with their claims about the function of dreaming and its relationship to consciousness, we argue that their endorsement of the Cartesian theatre metaphor is neither necessary nor desirable. Furthermore, if it were necessary then this endorsement would undermine their positive claims, as the Cartesian theatre metaphor is widely regarded as unsustainable. We (...) demonstrate this point and then develop an alternative formulation of their position that does not require the Cartesian theatre metaphor. Our positive goal is to clarify Hobson & Friston’s confusing usage of philosophical terminology, replacing it where possible with the more transparent language of the forward models framework. This will require some modifications to their account, which as it stands is philosophically and empirically unsustainable. (shrink)

Mechanistic explanation involves the attribution of functions to both mechanisms and their component parts, and function attribution plays a central role in the individuation of mechanisms. Our aim in this paper is to investigate the impact of a perspectival view of function attribution for the broader mechanist project, and specifically for realism about mechanistic hierarchies. We argue that, contrary to the claims of function perspectivalists such as Craver, one cannot endorse both function perspectivalism and mechanistic hierarchy realism: if functions are (...) perspectival, then so are the levels of a mechanistic hierarchy. We illustrate this argument with an example from recent neuroscience, where the mechanism responsible for the phenomenon of ephaptic coupling cross-cuts the more familiar mechanism for synaptic firing. Finally, we consider what kind of structure there is left to be realist about for the function perspectivalist. (shrink)

The 35 commentaries cover a wide range of topics and take many different stances on the issues explored by the target article. We have organised our response to the commentaries around three central questions: Are Friston blankets just Pearl blankets? What ontological and metaphysical commitments are implied by the use of Friston blankets? What kind of explanatory work are Friston blankets capable of? We conclude our reply with a short critical reflection on the indiscriminate use of both Markov blankets and (...) the free energy principle. (shrink)

Varela, Thompson, and Rosch illustrated their original presentation of the enactive theory of cognition with the example of a simple cellular automaton. Their theory was paradigmatically anti-computational, and yet automata similar to the one that they describe have typically been used to illustrate theories of computation, and are usually treated as abstract computational systems. Their use of this example is therefore puzzling, especially as they do not seem to acknowledge the discrepancy. The solution to this tension lies in recognizing a (...) hidden background assumption, shared by both Varela, Thompson, and Rosch and the computational theories of mind which they were responding to. This assumption is that computation requires representation, and that computational states must bear representational content. For Varela, Thompson, and Rosch, representational content is incompatible with cognition, and so from their perspective the automaton that they describe cannot, despite appearances, be computational. However, there now exist several accounts of computation that do not make this assumption, and do not characterize computation in terms of representational content. In light of these recent developments, we will argue that it is quite straightforward to characterize the enactive automaton as a non-representational computing mechanism, one that we do not think they should have any objections to.

This chapter draws an analogy between computing mechanisms and autopoietic systems, focusing on the non-representational status of both kinds of system (computational and autopoietic). It will be argued that the role played by input and output components in a computing mechanism closely resembles the relationship between an autopoietic system and its environment, and in this sense differs from the classical understanding of inputs and outputs. The analogy helps to make sense of why we should think of computing mechanisms as non-representational, (...) and might also facilitate reconciliation between computational and autopoietic/enactive approaches to the study of cognition.

Traditionally, computational theory (CT) and dynamical systems theory (DST) have presented themselves as opposed and incompatible paradigms in cognitive science. There have been some efforts to reconcile these paradigms, mainly, by assimilating DST to CT at the expenses of its anti-representationalist commitments. In this paper, building on Piccinini’s mechanistic account of computation and the notion of functional closure, we explore an alternative conciliatory strategy. We try to assimilate CT to DST by dropping its representationalist commitments, and by inviting CT to (...) recognize the functionally closed nature of some computational systems. (shrink)

Recently, some authors have begun to raise questions about the potential unity of 4E (enactive, embedded, embodied, extended) cognition as a distinct research programme within cognitive science. Two tensions, in particular, have been raised:(i) that the body-centric claims embodied cognition militate against the distributed tendencies of extended cognition and (ii) that the body/environment distinction emphasized by enactivism stands in tension with the world-spanning claims of extended cognition. The goal of this paper is to resolve tensions (i) and (ii). The proposal (...) is that a form of ‘wide computationalism’can be used to reconcile the two tensions and, in so doing, articulate a common theoretical core for 4E cognition. (shrink)

Physical Computation is the summation of Piccinini’s work on computation and mechanistic explanation over the past decade. It draws together material from papers published during that time, but also provides additional clarifications and restructuring that make this the definitive presentation of his mechanistic account of physical computation. This review will first give a brief summary of the account that Piccinini defends, followed by a chapter-by-chapter overview of the book, before finally discussing one aspect of the account in more critical detail.

Three experiments investigated response times for remember and know responses in recognition memory. RTs to remember responses were faster than RTs to know responses, regardless of whether the remember–know decision was preceded by an old/new decision or was made without a preceding old/new decision . The finding of faster RTs for R responses was also found when remember–know decisions were made retrospectively. These findings are inconsistent with dual-process models of recognition memory, which predict that recollection is slower and more effortful (...) than familiarity. Word frequency did not influence RTs, but remember responses were faster for words than for nonwords. We argue that the difference in RTs to remember and know responses reflects the time taken to make old/new decisions on the basis of the type of information activated at test. (shrink)

Does metacognition--the capacity to self-evaluate one's cognitive performance--derive from a mindreading capacity, or does it rely on informational processes? Joëlle Proust draws on psychology and neuroscience to defend the second claim. She argues that metacognition need not involve metarepresentations, and is essentially related to mental agency.

What is the proper role for scientists in policymaking? This paper explores various roles that scientists can play, with an eye to questions that these roles raise about value-neutrality and technocracy. Where much philosophical literature is concerned with the conduct of research or the transmission of research results to policymakers, I am interested in various non-research roles that scientists take on in policymaking. These include raising the alarm on issues, framing and conceptualising problems, formulating potential policies, assessing policy options for (...) expected efficacy, and more. I consider examples from climate change and Covid-19 policymaking. My intention is to encourage philosophers to expand their interest in values in science out from the conduct of research to the wide array of roles that scientists play in policymaking. The paper is therefore an overview of the landscape of potential research questions, rather than a presentation of a single argument. (shrink)

When an agent learns of an expert's credence in a proposition about which they are an expert, the agent should defer to the expert and adopt that credence as their own. This is a popular thought about how agents ought to respond to (ideal) experts. In a Bayesian framework, it is often modelled by endowing the agent with a set of priors that achieves this result. But this model faces a number of challenges, especially when applied to non-ideal agents (who (...) nevertheless interact with ideal experts). I outline these problems, and use them as desiderata for the development of a new model. Taking inspiration from Richard Jeffrey's development of Jeffrey conditioning, I develop a model in which expert reports are taken as exogenous constraints on the agent's posterior probabilities. I show how this model can handle a much wider class of expert reports (for example reports of conditional probabilities), and can be naturally extended to cover propositions for which the agent has no prior.

A common complaint among those involved in teaching the educational foundations is the reluctance of many trainee teachers to engage in issues of educational theory. This is particularly apparent with those trainees who are more concerned with managing classrooms of children than grappling with what are often abstract and difficult ideas. This paper considers the current use of educational stories as a pedagogical strategy in teacher training, and a story that has been used in this way is presented. It is (...) argued that teachers of the educational foundations disciplines can, via stories, appeal to the opposing tensions and schemata in students’ own minds, and this engagement can be enhanced when students are confronted with broader educational debates, perspectives and proposals. Stories provide abstract concepts with a necessary tension, they suggest a way of entering the theoretical via the concrete and they show students the personal relevance of certain debates, which may have previously appeared remote and obscure. The end result is that students are challenged to make decisions about matters of fundamental importance such as the kinds of teachers they will be and about the ethical commitment they will make to teaching.

To the Socratic injunction ‘Know Thyself’ one wonders how to respond. Presumably Socrates is asking us to attempt a project at which we are supposed to have some chance of success and this leads one to ask ‘ Can I know myself?’ One is led to ask it, but the question can seem rhetorical. Many would reply that of course one can do this because there is nothing easier for me to know than my own self. I do, therefore I (...) can. I know it simply by being myself. Not only this, one might regard knowledge of oneself as unavoidable so that the answer to the question ‘Can I know myself?’ is ‘Yes’ and the answer to the question ‘Can I avoid knowing myself?’ is ‘No’. Now if we cannot avoid knowing ourselves, if Socrates is asking us to do somethingwhich we inevitably do anyway, then he has certainly earned his reputation for irony. (shrink)

In our paper, we distinguish between two forms of memory knowledge: experiential memory knowledge and stored memory knowledge. We argue that, mutatis mutandis, the case that Pritchard makes for epistemological disjunctivism regarding perceptual knowledge can be made for epistemological disjunctivism regarding experiential memory knowledge. At the same time, we argue against a disjunctivist account of stored memory knowledge.

In a time of increasing polarization, how can we address sensitive topics and ensure that university classrooms remain places of healthy discussions and ethical deliberations? This paper addresses this important question by drawing on unique qualitative data from our students’ accounts of their experience in an organizational ethics course. We developed the course using a novel pedagogical strategy centered around the creation of an artistic portfolio. We find that student engagement in an alternative individual space, such as the artistic portfolio, (...) supports them in developing (inter)personal skills in preparation for constructive participation in sensitive discussions and ethical deliberation in the classroom. Additionally, engagement with the artistic portfolio provides them with an alternative means for alleviating tension that arises from these discussions and a space for expressing their opinions. Our findings highlight the role of the portfolio as an individual safe haven that supports teachers in facilitating a positive classroom atmosphere and guides students through challenging discussions and deliberations intrinsic to responsible management education. Considering these new insights, we advocate for a shift from a collective to an individual perspective on safety in academia. This transition liberates the classroom from the constraints and limitations often associated with the establishment of collective safe spaces. (shrink)

This paper demonstrates the ontological status of virtue as an instance of love within the cosmology of St. Maximus the Confessor. It shows that we may posit the real existence of a “virtue” in so far as we understand it to have its basis in, and to be an instance of love. Since God is love and the virtues are logoi, it becomes possible and beneficial to parallel the relationship between love and the virtues with Maximus’ exposition of the Logos (...) and the logoi. In particular, Vladimir Cvetković’s interpretation of the circle and radii analogy will be utilized. It will be shown that when one practices a virtue, one is practicing and participating in love, and, by extension, partaking in God. Within the context of Maximus’ cosmology, this means that practicing virtue and love is the ultimate purpose of humanity in its journey to gather all creation to communion with God. This paper is primarily an exposition of primary sources from St. Maximus, but discussion of the ontology of virtue is made with a view to bringing it into dialogue with modern theories of virtue ethics. This paper arises in part as a response to the August 2013 papers by Andrew Louth and Paul M. Blowers on the need for increased scholarship on Maximus and virtue ethics. (shrink)

Corporate philanthropy describes the action when a corporation voluntarily donates a portion of its resources to a societal cause. Although the thought of philanthropy invokes feelings of altruism, there are many objectives for corporate giving beyond altruism. Meeting strategic corporate objectives can be an important if not primary goal of philanthropy. The purpose of this paper is to share insights from a strategic corporate philanthropic initiative aimed at increasing the pool of frontline customer contact employees who are performance-ready, while supporting (...) curriculum development and infrastructure improvement for selected university business programs, creating a win-win situation for the company and the universities. This paper will address three objectives. First, we will examine the evolution of strategic philanthropy from the traditional view to its current position as a strategic option. Second, we will address the recruitment of front line talent needs (customer facing jobs in sales, customer service, and marketing) based on the profit maximization model of strategic philanthropy. Finally, we will offer conclusions and issues for future research. (shrink)

There are many cases in which, by making some great sacrifice, you could bring about either a good outcome or a very good outcome. In some of these cases, it seems wrong for you to bring about the good outcome, since you could bring about the very good outcome with no additional sacrifice. It also seems permissible for you not to make the sacrifice, and bring about neither outcome. But together, these claims seem to imply that you ought to bring (...) about neither outcome rather than the good outcome. And that seems very counterintuitive. In this paper, I develop this problem, propose a solution, and then draw out some implications both for how we should understand supererogation and for how we should approach charitable giving.

There has been much attention devoted in the last decade and especially in the last few years to Maximus the Confessor?s beliefs concerning sexual difference and its removal. The most important text on this topic is Ambiguum 41.
