Predictive processing approaches to the mind are increasingly popular in the cognitive sciences. This surge of interest is accompanied by a proliferation of philosophical arguments, which seek to either extend or oppose various aspects of the emerging framework. In particular, the question of how to position predictive processing with respect to enactive and embodied cognition has become a topic of intense debate. While these arguments are certainly of valuable scientific and philosophical merit, they risk underestimating the variety of approaches gathered (...) under the predictive label. Here, we first present a basic review of neuroscientific, cognitive, and philosophical approaches to PP, to illustrate how these range from solidly cognitivist applications—with a firm commitment to modular, internalistic mental representation—to more moderate views emphasizing the importance of ‘body-representations’, and finally to those which fit comfortably with radically enactive, embodied, and dynamic theories of mind. Any nascent predictive processing theory must take into account this continuum of views, and associated theoretical commitments. As a final point, we illustrate how the Free Energy Principle attempts to dissolve tension between internalist and externalist accounts of cognition, by providing a formal synthetic account of how internal ‘representations’ arise from autopoietic self-organization. The FEP thus furnishes empirically productive process theories by which to guide discovery through the formal modelling of the embodied mind. (shrink)

We distinguish between three philosophical views on the neuroscience of predictive models: predictive coding, predictive processing and predictive engagement. We examine the concept of active inference under each model and then ask how this concept informs discussions of social cognition. In this context we consider Frith and Friston’s proposal for a neural hermeneutics, and we explore the alternative model of enactivist hermeneutics.

Respiratory rhythms sustain biological life, governing the homeostatic exchange of oxygen and carbon dioxide. Until recently, however, the influence of breathing on the brain has largely been overlooked. Yet new evidence demonstrates that the act of breathing exerts a substantive, rhythmic influence on perception, emotion, and cognition, largely through the direct modulation of neural oscillations. Here, we synthesize these findings to motivate a new predictive coding model of respiratory brain coupling, in which breathing rhythmically modulates both local and global neural (...) gain, to optimize cognitive and affective processing. Our model further explains how respiratory rhythms interact with the topology of the functional connectome, and we highlight key implications for the computational psychiatry of disordered respiratory and interoceptive inference.

The Bayesian brain hypothesis, as formalized by the free-energy principle, is ascendant in cognitive science. But, how does the Bayesian brain obtain prior beliefs? Veissière and colleagues argue that sociocultural interaction is one important source. We offer a complementary model in which “interoceptive self-inference” guides the estimation of expected uncertainty both in ourselves and in our social conspecifics.

Bruineberg and colleagues report a striking confusion, in which the formal Bayesian notion of a “Markov blanket” has been frequently misunderstood and misapplied to phenomena of mind and life. I argue that misappropriation of formal concepts is pervasive in the “predictive processing” literature, and echo Richard Feynman in suggesting how we might resist the allure of cargo cult computationalism.

The mainstream science of consciousness offers a few predominate views of how the brain gives rise to awareness. Chief among these are the Higher-Order Thought Theory, Global Neuronal Workspace Theory, Integrated Information Theory, and hybrids thereof. In parallel, rapid development in predictive processing approaches have begun to outline concrete mechanisms by which interoceptive inference shapes selfhood, affect, and exteroceptive perception. Here, we consider these new approaches in terms of what they might offer our empirical, phenomenological, and philosophical understanding of consciousness (...) and its neurobiological roots.

An important objection to political liberalism is that it provides no means by which to decide conflicts between public and non-public reasons. This article develops John Rawls' idea of `reasoning from conjecture' as one way to argue for a commitment to public reason. Reasoning from conjecture is a form of non-public justification that allows political liberals to reason from within the comprehensive views of at least some unreasonable citizens. After laying out the basic features of this form of non-public justification, (...) this article responds to three objections based on concerns about insincerity, cultural imperialism, and the epistemic authority of those who reason from conjecture.

The notion of ‘durability’ plays a central role in the discourse, policies, and practices surrounding forced displacement. Yet, for all the talk of ‘durable solutions’ to refugee situations, durability is in many ways the quality most conspicuously absent in refugees' everyday lives and living spaces. As the world has grown progressively more inured to the practice of using provisional spaces of transit as permanent sites of residence, displaced persons are increasingly finding themselves trapped in spaces marked by a kind of (...) permanent temporariness. In this article, I sketch three different ways in which living for long periods of time in temporary spaces can harm inhabitants: first, I argue that non-durability in the home can undermine cognitive function; second, that it can attenuate various forms of agency; and third, that it fails to furnish a ground on which refugees can build meaningful lives and futures for themselves. I conclude by arguing that the deprivation of durable living conditions is not only harmful, but wrongful. (shrink)

A common objection to the idea of public reason is that it cannot resolve fundamental political issues because it excludes too many moral considerations from the political domain. Following an important but often overlooked distinction drawn by Gerald Gaus, there are two ways to understand this objection. First, public reason is often said to be inconclusive because it fails to generate agreement on fundamental political issues. Second, and more radically, some critics have claimed that public reason is indeterminate because it (...) cannot provide any citizen with sufficient reason(s) for making important political decisions. Against the first of these objections, I argue that the purpose of public reason is not to end reasonable disagreement. Rather, it is to provide a suitable framework of values and principles within which citizens may resolve their moral and political differences. Against the second objection, I argue, first, that the indeterminacy of public reason is much less common than its inconclusiveness; and, second, that there are second-order decision-making strategies that may enable citizens to cope with cases of indeterminacy. The incompleteness of public reason, whether it takes the form of inconclusiveness or indeterminacy, is not a reason for citizens to abandon their commitment to public justification. (shrink)

Encampment continues to be one of the dominant modes of responding to refugee situations. I suggest that we would do well to conceive of the wrongfulness of refugee camps not just in terms of their effects, but also in terms of their function. I endorse the view that camps currently function primarily to contain displaced persons and develop a novel conception of the wrong of encampment in terms of that function. Drawing on Heidegger's account of the spatiality proper to different (...) entities, I argue that practices of containment reduce refugees to the status of objects to be, in effect, immobilized and stored away for an indeterminate amount of time.

The subject of this book is moral change, including moral progress and regression. The intention is to use the best thinking about the evolution of morality and the best available social science research to determine the possibilities for progressive change in human moralities by examining important morally progressive changes that have already occurred, in order to determine the social conditions that are conducive to moral progress.

Various theorists contend that we may live in a computer simulation. David Chalmers in turn argues that the simulation hypothesis is a metaphysical hypothesis about the nature of our reality, rather than a sceptical scenario. We use recent work on consciousness to motivate new doubts about both sets of arguments. First, we argue that if either panpsychism or panqualityism is true, then the only way to live in a simulation may be as brains-in-vats, in which case it is unlikely that (...) we live in a simulation. We then argue that if panpsychism or panqualityism is true, then viable simulation hypotheses are substantially sceptical scenarios. We conclude that the nature of consciousness has wide-ranging implications for simulation arguments. (shrink)

While tens of thousands of people across the United States serve on hospital and other healthcare ethics committees, almost no carefully prepared educational material exists for HEC members. Ethics by Committee is a one volume collection of chapters developed exclusively for this educational purpose. Experts in bioethics, clinical consultation, health law, and social psychology from across the country contribute chapters on ethics consultation, education, and policy development.

Abstract: Recent years have witnessed a revival of interest in relativism. Proponents have defended various accounts that seek to model the truth-conditions of certain propositions along the lines of standard possible world semantics. The central challenge for such views has been to explain what advantage they have over contextualist theories with regard to the possibility of disagreement. I will press this worry against Max Kölbel’s account of faultless disagreement. My case will proceed along two distinct but connected lines. First, I (...) will argue that the sense of faultlessness made possible by his relativism conflicts with our intuitive understanding of disagreement. And second, that his meta-epistemological commitments are at odds with the socio-epistemic function of disagreement. This latter problem for relativistic accounts of truth has thus far been largely ignored in the literature. (shrink)

An influential strand of neo-Aristotelianism, represented by writers such as Philippa Foot, holds that moral virtue is a form of natural goodness in human beings, analogous to deep roots in oak trees or keen vision in hawks. Critics, however, have argued that such a view cannot get off the ground, because the neo-Aristotelian account of natural normativity is untenable in light of a Darwinian account of living things. This criticism has been developed most fully by William Fitzpatrick in his book (...) Teleology and the Norms of Nature . In this paper, I defend the neo-Aristotelian account of natural normativity, focusing on Fitzpatrick's arguments. I argue that a natural goodness view is not impugned by an evolutionary account. Nor can neo-Aristotelian life form judgments be replaced by an evolutionary view of living things. (shrink)

This essay defends Aristotelian naturalism against the objection that it is naïvely optimistic, and contrary to empirical research, to suppose that virtues like justice are naturally good while vices like injustice are naturally defective. This objection depends upon the mistaken belief that our knowledge of human goodness in action and choice must come from the natural sciences. In fact, our knowledge of goodness in human action and character depends upon a practical understanding that is possessed by someone not qua scientist (...) but qua practically wise person. I spell out some key features of this knowledge of human form, including its relation to practical reasons and its similarity to the “know-how” of crafts-persons. My account of virtue as knowledge of human form sheds light on the Aristotelian thesis that humans live according to an understanding of their own form. My account also clarifies the kinship and the divergence between Aristotelian and Kantian ethics. (shrink)

What mechanisms underlie children’s language production? Structural priming—the repetition of sentence structure across utterances—is an important measure of the developing production system. We propose its mechanism in children is the same as may underlie analogical reasoning: structure-mapping. Under this view, structural priming is the result of making an analogy between utterances, such that children map semantic and syntactic structure from previous to future utterances. Because the ability to map relationally complex structures develops with age, younger children are less successful than (...) older children at mapping both semantic and syntactic relations. Consistent with this account, 4-year-old children showed priming only of semantic relations when surface similarity across utterances was limited, whereas 5-year-olds showed priming of both semantic and syntactic structure regardless of shared surface similarity. The priming of semantic structure without syntactic structure is uniquely predicted by the structure-mapping account because others have interpreted structural priming as a reflection of developing syntactic knowledge.

A very liberal sexual ethics now holds sway in Western culture, such that mutual consent alone is widely seen as morally legitimizing almost any sexual activity between adults. It is further commonly assumed by both philosophers and nonphilosophers that arguing for some alternative to liberal sexual ethics requires appeal to ethical commands specific to some religious tradition or other. The purpose of this paper is to challenge that assumption by suggesting some purely naturalistic and independently-plausible premises that can be used (...) to argue for a much more conservative system of sexual ethics than is widely accepted today.

The central claim of Aristotelian naturalism is that moral goodness is a kind of species-specific natural goodness. Aristotelian naturalism has recently enjoyed a resurgence in the work of philosophers such as Philippa Foot, Rosalind Hursthouse, and Michael Thompson. However, any view that takes moral goodness to be a type of natural goodness faces a challenge: Granting that moral goodness is natural goodness for human beings, why should we care about being good human beings? Given that we are rational creatures who (...) can ‘step back’ from our nature, why should we see human nature as authoritative for us? This is the authority-of-nature challenge. In this essay, I state this challenge clearly, identify its deep motivation, and distinguish it from other criticisms of Aristotelian naturalism. I also articulate what I consider the best response, which I term the practical reason response. This response, however, exposes Aristotelian naturalism to a new criticism – that it has abandoned the naturalist claim that moral goodness is species-specific natural goodness. Thus, I argue, Aristotelian naturalists appear to face a dilemma: Either they cannot answer the authority-of-nature challenge, or in meeting the challenge they must abandon naturalism. Aristotelian naturalists might overcome this dilemma, but doing so is harder than some Aristotelians have supposed. In the final sections of the paper, I examine the difficulties in overcoming the dilemma, and I suggest ways that Aristotelians might answer the authority-of-nature challenge while preserving naturalism.

This paper argues that grammatical constructions, specifically argument structure constructions that determine the “who did what to whom” part of sentence meaning and how this meaning is expressed syntactically, can be considered a kind of relational category. That is, grammatical constructions are represented as the abstraction of the syntactic and semantic relations of the exemplar utterances that are expressed in that construction, and it enables the generation of novel exemplars. To support this argument, I review evidence that there are parallel (...) behavioral patterns between how children learn relational categories generally and how they learn grammatical constructions specifically. Then, I discuss computational simulations of how grammatical constructions are abstracted from exemplar sentences using a domain-general relational cognitive architecture. Last, I review evidence from adult language processing that shows parallel behavioral patterns with expert behavior from other cognitive domains. After reviewing the evidence, I consider how to integrate this account with other theories of language development. (shrink)

Kant's Moral Religion argues that Kant's doctrine of religious belief if consistent with his best critical thinking and, in fact, that the "moral arguments"--along with the faith they justify--are an integral part of Kant's critical thinking.

In learning chemistry at the entry level, many learners labor under misconceptions about the subject matter that are so fundamental that they are typically never addressed. A fundamental misconception in chemistry appears to arise from an adding of existing phenomenal concepts to newly-acquired chemical concepts, so that beginning learners think of chemical entities as themselves having the very same ‘macro’ properties that we observe through the senses. Those who teach or practice chemistry never acquire these misconceptions because they were able (...) to naturally pick up the nature of the subject to begin with. But as a result, they remain unaware of the foundational assumptions and understanding that they operate with and that many beginning learners persistently lack. Thus, a systematic picture of the workings of chemical theory as they relate to observable phenomena needs to be elucidated so that the attention of chemical educators is drawn to the fundamental understanding of the subject that they already possess and that beginning learners of chemistry lack, so that beginning learners can be given the opportunity to gain an understanding of how chemical explanations are in general related to observable phenomena. The ‘layered’ way in which chemical and physical entities are related to each other within chemical theory can also be clarified in this way. To afford this picture, the philosophical concepts of supervenience and emergence are explained and applied to chemistry, as philosophers of chemistry have already done. The result provides a model for teaching chemistry that, if consistently applied, has the potential to greatly enhance fundamental understanding of the subject matter. (shrink)

John Locke's theory of toleration has been criticized as having little relevance for politics today because it rests on controversial theological foundations. Although there have been some recent attempts to develop secular; or publicly accessible, arguments out of Locke's writings, these tend to obscure and distort the religious arguments that Locke used to defend toleration. More importantly, these efforts ignore the role that religious arguments may play in supporting the development of a normative consensus on the legitimacy of liberal political (...) principles. Bracketing the search for publicly accessible justifications makes it possible to appreciate the continued relevance of Locke's religious arguments for toleration. (shrink)
