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.

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.

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.

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)

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. There has been mixed reception of this text, with some scholars advocating that Maximus believes that sexual difference was absent from original human nature and will return to such a state in the eschaton; and other scholars believing that this should be read (...) as a metaphorical absence. This article re-evaluates the text in question and argues that the former position should be maintained. It goes some way to bring together current scholarship on the text and to answers questions that arise from the opposing reading. (shrink)

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.

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 intuition that knowledge is more valuable than true belief generates the value problem in epistemology. The aim in this paper is to focus on the intuitive notion of knowledge itself, in the context of the value problem, and to attempt to bring out just what it is that we intuitively judge to be valuable. It seems to me that the value problem brings to the fore certain commitments we have to the intuitive notion of knowledge, which, if we take (...) seriously, reveal that we actually think of knowledge as an irreducible factive mental state.

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.

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.

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)

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.

In On the Soul and the Resurrection, St Macrina and St Gregory of Nyssa consider what the soul is, and its relationship to our body and identity. Gregory notes the way that our bodies are always changing, and asks which is most truly our ‘real’ body if we are always in a state of growth, decay and transience? What physical body will be with us at the resurrection? If our body is as important to our identity as our soul, then (...) who am I when my body changes? Macrina answers that our identity is bodily, but that the sufferings and passages of time that alter our bodies mean that we are an imperfect version of ourselves in this life. The person that we will be at the resurrection will be free from the influence of evil and the ravages of impermanence. Modern-day science fiction wrestles with Gregory’s problem—where is my identity located? If my body is altered beyond recognition, or my mind transferred to a new body, am I still me? These cyberpunk and transhumanist worries call to mind the ancient topic of mind/body dualism, and Macrina and Gregory have some surprisingly relevant insights to offer to our contemporary technological dilemmas.

I argue that anarchist ideas for organising human communities could be a useful practical resource for Christian ethics. I demonstrate this firstly by introducing the main theological ideas underlying Maximus the Confessor’s ethics, a theologian respected and important in a number of Christian denominations. I compare practical similarities in the way in which ‘love’ and ‘well-being’ are interpreted as the telos of Maximus and Peter Kropotkin’s ethics respectively. I further highlight these similarities by demonstrating them in action when it comes (...) attitudes towards property. I consequently suggest that there are enough similarities in practical aims, for Kropotkin’s ideas for human organising to be useful to Christian ethicists. (shrink)

__Teachers Bridging Difference_ describes how educators can move out of their comfort zones and practice connecting with others across differences to become culturally responsive teachers. _Based on a course developed for preservice teachers, the book illustrates how educators can draw on the visual arts as a resource to explore their own identities and those of their students, and how to increase their understanding of the ways our lives intersect across sociocultural differences. Drawing on scholarship from multiple disciplines and from her (...) own experience, Marit Dewhurst identifies four stances designed to help educators connect with students in today’s multicultural classrooms. To practice these stances, the book introduces eight arts-based activities that can be used by educators in multiple contexts. Ranging from community maps and conversation portraits to scenario comics and reflection zines, the activities are designed to be accessible to even those with little arts experience and can be executed with a wide variety of materials and media. Unique and timely, _Teachers Bridging Difference _is an arts-based tool kit for teachers interested in exploring issues of identity and difference as a foundation for creating a more just and equal society.

I explore virtue and love in Maximus the Confessor’s theology with an aim to drawing an ethics from it relevant to the present day. I use a meta-ethical framework derived from contemporary virtue ethics and look at virtue as an instance of love within the context of Maximus’ cosmic theology. Virtue becomes a path that leads us towards love – who is God Himself. Virtue is thus about movement towards theosis. I describe virtue as a relationship between humans and God, (...) brought about through the mutual practice of a life of ascesis from humans and grace from God. I look at the mediatoral role of humans as microcosms gathering up the universe in an image of Christ’s activity. In particular I analyse the way that human activity is simultaneously cosmic and ascetic; personal and communal. The ethic of virtue that we pursue is always caught up in a conversation about what creation gathered in love looks like. Using a number of tools derived from Maximus’ thought, I suggest that this ethics will necessarily transform our current communities and personal practices. Recognising the cosmic dimension of personal behaviour means that our communities must be scrutinised as extensions of our actions. As an example, I critique the state as an inadequate form of loving relationship, illustrating its systemic reliance on violence and ideologies of alienation and hatred. I give examples of alternative ways of human organising drawn from anarchist thought that might better enable us to love and, more importantly, enable us to call to account failures to love. I conclude that to seek theosis after the manner Maximus describes involves recognising our personal and communal failures to love. His holistic understanding of human purpose can help us see the cosmic dimension to personal ascetic practice and consequently set our sights on a more cosmic vision of love here in the present world.

In this article I deal with a problem concerning the ‘divisions of nature’ in Maximus the Confessor’s Ambiguum 41. These ‘divisions’ are five categories that describe how creatures differ from one another and God in natural, physical ways. Later, Maximus discusses the way that the human person may follow Christ to mediate between these divisions. This becomes problematic however as the ascetic practice associated with this mediating power occurs within a sphere we usually define as ‘ethical’. In conflating these physical (...) and ethical dimensions it becomes unclear how our actions can overcome and unite the physical differences described in Maximus’ divisions of nature’. In this article I demonstrate how this problem may be overcome by using Maximus’ own logic of division and unity within this very Ambiguum. It is shown that Maximus does not see these two spheres of ‘physical’ and ‘ethical’ as separate. The ethical is part of the natural trajectory of the physical. Maximus is simply talking about the natural world and the way in which it moves towards its Creator. I build upon Tollefsen’s work on universals and Cvetković’s on circle and radii analogy in order to support this position. Finally, I suggest that we ought to think of Maximus’ ‘divisions of nature’ in this Ambiguum rather as ‘divisions and unity of nature’, since physical differences also promise the possibility of movement of all creation toward unity with God.

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.

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 U.S. stock market is one of the largest and most complex marketplaces in the global financial system. Over the past several decades, this market has evolved at multiple structural and temporal scales. New exchanges became active, and others stopped trading, regulations have been introduced and adapted, and technological innovations have pushed the pace of trading activity to blistering speeds. These developments have supported the growth of a rich machine-trading ecology that leads to qualitative differences in trading behavior at human (...) and machine time scales. We conduct a longitudinal analysis of comprehensive market data to quantify nonstationary dynamics throughout this system. We quantify the relationship between fluctuations in the number of active trading venues and realized opportunity costs experienced by market participants. We find that information asymmetries, in the form of quote dislocations, predict market-wide volatility indicators. Lastly, we uncover multiple micro-to-macro level pathways, including those exhibiting evidence of self-organized criticality. (shrink)

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)
