Phenotypic plasticity integrates the insights of ecological genetics, developmental biology, and evolutionary theory. Plasticity research asks foundational questions about how living organisms are capable of variation in their genetic makeup and in their responses to environmental factors. For instance, how do novel adaptive phenotypes originate? How do organisms detect and respond to stressful environments? What is the balance between genetic or natural constraints (such as gravity) and natural selection? The author begins by defining phenotypic plasticity and detailing its history, including (...) important experiments and methods of statistical and graphical analysis. He then provides extended examples of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media. (shrink)

This paper considers the connections between semantic shiftiness (plasticity), epistemic safety and an epistemic theory of vagueness as presented and defended by Williamson (1996a, b, 1997a, b). Williamson explains ignorance of the precise intension of vague words as rooted in insensitivity to semantic shifts: one’s inability to detect small shifts in intension for a vague word results in a lack of knowledge of the word’s intension. Williamson’s explanation, however, falls short of accounting for ignorance of intension.

Ghosh introduces the term 'plastic turn' and gives a new direction for how we can interpret and experience the turn today. By what he calls the material-aesthetic, he opens up a fresh direction in our experience and understanding of plastic through the correspondence that plastic as a material brings with the aesthetic that it inspires and figures"-.

The doctrine that the character of our perceptual knowledge is plastic, and can vary substantially with the theories embraced by the perceiver, has been criticized in a recent paper by Fodor. His arguments are based on certain experimental facts and theoretical approaches in cognitive psychology. My aim in this paper is threefold: to show that Fodor's views on the impenetrability of perceptual processing do not secure a theory-neutral foundation for knowledge; to show that his views on impenetrability are almost certainly (...) false; and to provide some additional arguments for, and illustrations of, the theoretical character of all observation judgments.

and apply it to various examples of neural plasticity in which input is rerouted intermodally or intramodally to nonstandard cortical targets. In some cases but not others, cortical activity ‘defers’ to the nonstandard sources of input. We ask why, consider some possible explanations, and propose a dynamic sensorimotor hypothesis. We believe that this distinction is important and worthy of further study, both philosophical and empirical, whether or not our hypothesis turns out to be correct. In particular, the question of how (...) the distinction should be explained is linked to explanatory gap issues for consciousness. Comparative and absolute explanatory gaps should be distinguished: why does neural activity in a particular area of cortex have this qualitative expression rather than that, and why does it have any qualitative expression at all? We use the dominance/deference distinction to address the comparative gaps, both intermodal and intramodal. We do so not by inward scrutiny but rather by expanding our gaze to include relations between brain, body and environment. (shrink)

The growing field of evo-devo is increasingly demonstrating the complexity of steps involved in genetic, intracellular regulatory, and extracellular environmental control of the development of phenotypes. A key result of such work is an account for the remarkable plasticity of organismal form in many species based on relatively minor changes in regulation of highly conserved genes and genetic processes. Accounting for behavioral plasticity is of similar potential interest but has received far less attention. Of particular interest is plasticity in communication (...) systems, where human language represents an ultimate target for research. The present paper considers plasticity of language capabilities in a comparative framework, focusing attention on examples of a remarkable fact: Whereas there exist design features of mature human language that have never been observed to occur in non-humans in the wild, many of these features can be developed to notable extents when non-humans are enculturated through human training. These examples of enculturated developmental plasticity across extremely diverse taxa suggest, consistent with the evo-devo theme of highly conserved processes in evolution, that human language is founded in part on cognitive capabilities that are indeed ancient and that even modern humans show self-organized emergence of many language capabilities in the context of rich enculturation, built on the special social/ecological history of the hominin line. Human culture can thus be seen as a regulatory system encouraging language development in the context of a cognitive background with many highly conserved features. (shrink)

In Reading in the Brain, Stanislas Dehaene presents a compelling account of how the brain learns to read. Central to this account is his neuronal recycling hypothesis: neural circuitry is capable of being ‘recycled’ or converted to a different function that is cultural in nature. The original function of the circuitry is not entirely lost and constrains what the brain can learn. It is argued that the neural niche co-evolves with the environmental niche in a way that does not undermine (...) the core ideas of neuronal recycling, but which is quite different from the models of cognitive and cultural evolution provided by evolutionary psychology and epidemiology. Dehaene contrasts neuronal recycling with a naïve model of the brain as a general learning device that is unconstrained in what it can learn. Consequently a tension develops in Dehaene's account of the role of plasticity in the acquisition of language. It is argued that the functional and structural changes in the brain that Dehaene documents in great detail are driven by learning and that this learning-driven plasticity does not commit us to a naïve model of the brain.

Consciousness is known to be limited in processing capacity and often described in terms of a unique processing stream across a single dimension: time. In this paper, we discuss a purely temporal pattern code, functionally decoupled from spatial signals, for conscious state generation in the brain. Arguments in favour of such a code include Dehaene et al.'s long-distance reverberation postulate, Ramachandran's remapping hypothesis, evidence for a temporal coherence index and coincidence detectors, and Grossberg's Adaptive Resonance Theory. A time-bin resonance model (...) is developed, where temporal signatures of conscious states are generated on the basis of signal reverberation across large distances in highly plastic neural circuits. The temporal signatures are delivered by neural activity patterns which, beyond a certain statistical threshold, activate, maintain, and terminate a conscious brain state like a bar code would activate, maintain, or inactivate the electronic locks of a safe. Such temporal resonance would reflect a higher level of neural processing, independent from sensorial or perceptual brain mechanisms. (shrink)

This chapter analyzes the notion of human nature and the concept of inner nature from the perspective of developmental systems theory. It explores the folkbiology of human nature and looks at three features associated with traits that are expressions of the inner nature that organisms inherit from their parents: fixity, typicality, teleology.

Most meanings we express belong to large families of variant meanings, among which it would be implausible to suppose that some are much more apt for being expressed than others. This abundance of candidate meanings creates pressure to think that the proposition attributing any particular meaning to an expression is modally plastic: its truth depends very sensitively on the exact microphysical state of the world. However, such plasticity seems to threaten ordinary counterfactuals whose consequents contain speech reports, since it is (...) hard to see how we could reasonably be confident in a counterfactual whose consequent can be true only if a certain very finely tuned microphysical configuration obtains. This essay develops the foregoing puzzle and explores several possible solutions. (shrink)

ABSTRACT Education appears to bear responsibility on the one hand to do justice to society’s need for reproduction and continuation, and on the other to do justice to the individual’s capacity for and need to express resistance, critique and political action. How we navigate this problem is tied to how we understand justice. ‘Plastic justice’ is the suggestion that questions concerning justice and education might find a materialist expression instead of the usual transcendental ideals of justice. In this perspective, ‘justice’ (...) appears not as an achievable ideal but as a philosophical void that allows us to identify and react to injustice. An example of this is the void that allows for social selection – in the form of admissions or exams – that must be kept open if we wish to avoid encouraging social conformism and reproduction.

The article presents an account of the visual relations created by garments through their plastic formants, examining the role played by form, material, and composition in creating body hierarchies that produce prescribed behaviors between different subjects. The work dissects the concept of thematic role from Greimasian theory, investigating the manners in which an eighteenth-century wedding dress presents the chaining of programs governing materials, garments, and the body in the production of narrative interactions between subjects. The work utilizes a combination of (...) Greimas’ method with the Visual Semiotics continued by Floch and Oliveira, as well as Hammad’s Semiotics of Space which permit the exam of optical relations created in the body through its clothing – relations that can be read as manifesting values that are both historically and socially determined, or in the act of apprehension of an object. The eighteenth century provides a type of “original” case, whose results are pertinent to a broader study of the relations between body and dress: the work concludes with the understanding that Fashion changes through the transit of values and roles invested in the body and dress – a set of changes closely linked to the construction of social roles.

In addition to considerable debate in the recent evolutionary literature about the limits of the Modern Synthesis of the 1930s and 1940s, there has also been theoretical and empirical interest in a variety of new and not so new concepts such as phenotypic plasticity, genetic assimilation and phenotypic accommodation. Here we consider examples of the arguments and counter- arguments that have shaped this discussion. We suggest that much of the controversy hinges on several misunderstandings, including unwarranted fears of a general (...) attempt at overthrowing the Modern Synthesis paradigm, and some fundamental conceptual confusion about the proper roles of phenotypic plasticity and natural selection within evolutionary theory.

In recent years, many scholars have suggested that the Baldwin effect may play an important role in the evolution of language. However, the Baldwin effect is a multifaceted and controversial process and the assessment of its connection with language is difficult without a formal model. This paper provides a first step in this direction. We examine a game-theoretic model of the interaction between plasticity and evolution in the context of a simple language game. Additionally, we describe three distinct aspects of (...) the Baldwin effect: the Simpson– Baldwin effect, the Baldwin expediting effect and the Baldwin optimizing effect. We find that a simple model of the evolution of language lends theoretical plausibility to the existence of the Simpson– Baldwin and the Baldwin optimizing effects in this arena, but not the Baldwin expediting effect.

Probably colour is the best worked-out example of allegedly neurophysiologically innate response categories determining percepts and percepts determining concepts, and hence biology fixing the basic categories implicit in the use of language. In this paper I argue against this view and I take C. L. Hardin's Color for Philosophers [1988] as my main target. I start by undermining the view that four unique hues stand apart from all other colour shades (Section 2) and the confidence that the solar spectrum is (...) naturally divided into four categories (Section 3). For such categories to be truly universal, they have to be true for all peoples and in Section 4 I show that Berlin and Kay's [1969] widely quoted theory of basic colour categories is not sufficiently supported to lend it any credibility.Having disposed of the view that inspection of language or ‘pure’ perception unveils the universal colour categories. I turn to neurophysiological and psychophysical theories of colour vision to see whether they provide a more solid basis for deciding what the innate response categories are. In Section 5 I show that Hardin's account of the opponent-process theory neither supports his view that ‘colour-coding’takes place early in the visual neural pathway, nor his view that knowledge of colour vision science will help us solve many philosophical mysteries about colour.In Section 6 I give a more detailed review of what is known today about the neurophysiology of colour vision and I show that there's nothing in the brain which could be called a colour module, let alone a module with homunculi for particular basic colour categories. In Section 7 I show that psychophysical models do not support such rigid constraints on category formation either. Hence (Section 8), at least in the case of colour, current science supports a plasticity in the formation of categories that goes far beyond the requirements of those naturalistic philosophers who would like to ground primitive concepts in biology.

Sensation is a concept with a conflicted philosophical history. It has found as many allies as enemies in nearly every camp from empiricism to poststructuralism. Polyvalent, with an uncertain referent, and often overshadowed by intuition, perception, or cognition, sensation invites as much metaphysical speculation as it does dismissive criticism. -/- The promise of sensation has certainly not been lost on the phenomenologists who have sought to ‘rehabilitate’ the concept. In Plastic Bodies, Tom Sparrow argues that the phenomenologists have not gone (...) far enough, however. Alongside close readings of Merleau-Ponty and Levinas, he digs into an array of ancient, modern, and contemporary texts in search of the resources needed to rebuild the concept of sensation after phenomenology. He begins to assemble a speculative aesthetics that is at once a realist theory of sensation and a philosophy of embodiment that breaks the form of the ‘lived’ body. Maintaining that the body is fundamentally plastic and that corporeal identity is constituted by a conspiracy of sensations, he pursues the question of how the body fits into/fails to fit into its aesthetic environment and what must be done to increase the body’s power to act and exist.

The developing mammalian heart responds to a variety of conditions, including changes in nutrient availability, blood oxygenation, hemodynamics, or tissue homeostasis, with impressive growth plasticity. This ensures the formation of a functional and normal sized organ by birth. During embryonic and fetal development the heart is exposed to various physiological and potentially pathological changes in the intrauterine environment which dramatically impact on normal cardiac function, tissue composition, and morphology. This paper summarizes the mechanisms employed by the embryonic and fetal heart (...) to adapt to various intrauterine challenges to prevent or minimize postnatal consequences of impaired cardiac development. Future investigations of this growth plasticity might lead to new therapeutic strategies for the prevention of cardiac disease in postnatal life. (shrink)

Merleau-Ponty’s explication of concrete or practical movement by way of the Schneider case could be read as ending up close to automatism, neglecting its flexibility and plasticity in the face of obstacles. It can be contended that he already goes off course in his explication of Schneider’s condition. Rasmus Jensen has argued that he assimilates a normal person’s motor intentionality to the patient’s, thereby generating a vacuity problem. I argue that Schneider’s difficulties with certain movements point to a means of (...) broadening Merleau-Ponty’s account of concrete movement, one that he broaches without exploiting. What could do more work is his recognition of a transposition capacity - and hence of a plasticity - in the healthy body’s skill schema. As well as avoiding vacuity, he could forestall the appearance of a dichotomy between practical coping and creativity. (shrink)

Does sovereignty have a future in the 21st century? Through a sustained engagement with the work of the Italian philosopher Giorgio Agamben, and against the background of contemporary political phenomena, Arne De Boever explores what positive political possibilities the notion of sovereignty might still hold. Using the philosophy of Catherine Malabou, he argues that these possibilities reside in an aesthetic reconceptualisation of sovereignty as a plastic power that is able to give, receive and explode the forms of our political future.

Neural plasticity has been invoked as a powerful argument against nativism. However, there is a line of argument, which is well exemplified by Pinker and more recently by Laurence and Margolis The conceptual mind: new directions in the study of concepts, MIT, Cambridge, 2015) with respect to concept nativism, according to which even extreme cases of plasticity show important innate constraints, so that one should rather speak of “constrained plasticity”. According to this view, cortical areas are not really equipotential, they (...) perform instead different kinds of computation, follow essentially different learning rules, or have a fixed internal structure acting as a filter for specific categories of inputs. We intend to analyze this argument, in the light of a review of current neuroscientific literature on plasticity. Our conclusion is that Laurence and Margolis are right in their appeal to innate constraints on connectivity—a thesis that is nowadays welcome to both nativists and non-nativists —but there is little support for their claim of further innate differentiation between and within cortical areas. As we will show, there is instead strong evidence that the cortex is characterized by the indefinite repetition of substantially identical computational units, giving rise in any of its portions to Hebbian, input-dependent plasticity. Although this is entirely compatible with the existence of innate constraints on the brain’s connectivity, the cerebral cortex architecture based on a multiplicity of maps correlating with one another has important computational consequences, a point that has been underestimated by traditional connectionist approaches.

This article explores the complexities of Marcuse’s philosophical anthropology in light of Foucault’s criticisms of Marcuse and the Frankfurt School. While Marcuse’s theory of human nature is grounded upon a dialectical conception of essential human potentialities striving for realization, it secretes a radically plastic conception of life that undermines all anthropological essentialism. This fundamental tension between essentialist and plastic conceptions of human nature has significant implications for rethinking Marcuse’s (...) project and legacy. (shrink)

Many researchers consider language to be definitionally unique to humans. However, increasing evidence suggests that language emerged via a series of adaptations to neural systems supporting earlier capacities for visuomotor integration and manual action. This paper reviews comparative neuroscience evidence for the evolutionary progression of these adaptations. An outstanding question is how to mechanistically explain the emergence of new capacities from pre-existing circuitry. One possibility is that human brains may have undergone selection for greater plasticity, reducing the extent to which (...) brain organization is hard-wired and increasing the extent to which it is shaped by socially transmitted, learned behaviors. Mutations that made these new abilities easier or faster to learn would have undergone positive selection, and over time, the neural changes once associated with individual neural plasticity would tend to become heritable, innate, and fixed. Clearly, though, language is not entirely “innate;” it does not emerge without the requisite environmental input and experience. Thus, a mechanistic explanation for the evolution of language must address the inherent trade-off between the evolutionary pressure for underlying neural systems to be flexible and sensitive to environmental input vs. the tendency over time for continually adaptive behaviors to become reliably expressed in an early-emerging, canalized, less flexible manner.

The article’s aim is to present plastic semiotics, one of the most recent branches of the Greimassian School. In his Structural Semantics: An Attempt at a Method (1966) Algirdas Julius Greimas stated that sensorial perception was the dimension in which the grasping of meaning takes place, but explicit principles of the analysis of this nonlinguistic dimension were published only years later, in his article “Figurative semiotics and plastic semiotics” (1984). Since then, plastic semiotics has been leading independent existence, focused on (...) the eff ects of sense generated by the form and the substance of expression. Plastic analysis has turned out to be a fruitful approach not only in the field of visual studies, but also in the research into other sensorial expressions.Статья знакомит с одной из наиболее молодых ветвей греймасовской семиотики – пластической. В книге Греймаса ≪Структурная семантика: поиск метода≫ (1966) чувственное восприятие было определено как измерение, в котором осуществляется схватывание смысла/значения. Основы анализа этого неязыкового измерения были изложены им позднее в статье ≪Фигуративная семиотика и пластическая семиотика≫ (1984). С тех пор пластическая семиотика превратилась в самостоятельную дисциплину, которая фокусируется на сенсорных эффектах смысла, произведенных формой и сущностью выражения. Пластический анализ оказался плодотворным подходом не только в области визуальных исследований, но и в исследованиях других сенсорных выражений.Artikli eesmargiks on tutvustada plastilist semiootikat, uht Greimase koolkonna uuemat haru.

In a recent paper, Chunghyoung Lee argues that, because zygotes are developmentally plastic, they cannot be numerically identical to the singletons into which they develop, thereby undermining conceptionism.

This essay defends the view that, as embodied, our identities are necessarily dependent on the aesthetic environment. Toward this end, it examines the renewal of the concept of sensation (aisthesis) in phenomenology, but then concludes that the methodology and metaphysics of phenomenology must be abandoned in favor of an ontology that sees corporeal identity as generated by the materiality of aesthetic relations. It is suggested that such an ontology is available in the work of Spinoza, which helps break down the (...) natural/ artificial and human/nonhuman distinctions, and can thereby engender an environmental ethics grounded in aesthetic relations. An explication of body/ world dependence is provided via the concept of plasticity and a properly Spinozist aesthetics is invoked, but remains to be worked out. (shrink)

In this paper, I present an emerging explanatory framework about ageing and care. In particular, I focus on how, in contrast to most classical accounts of ageing, biomedicine today construes the ageing process as a modifiable trajectory. This framing turns ageing from a stage of inexorable decline into the focus of preventive strategies, harnessing the functional plasticity of the ageing organism. I illustrate this shift by focusing on studies of the demographic dynamics in human population, observations of ageing as an (...) intraspecifically heterogenous phenotype, and the experimental manipulation of longevity, in both model organisms and humans. I suggest that such an explanatory framework about ageing creates the epistemological conditions for the rise of a peculiar form of prevention that does not aim to address a specific condition. Rather it seeks to stall the age-related accumulation of molecular damage and functional deficits, boosting individual resilience against age-related decline. I call this preventive paradigm “ground-state prevention.” While new, ground-state prevention bears conceptual resemblance to forms of medical wisdom prominent in classic Galenic medicine, as well as in the Renaissance period.

This paper explores the events surrounding a string of robberies from the homes of young celebrities living in Los Angeles County by a group of teenagers referred to by the media as “The Bling Ring.” It argues that the group demonstrates the intersections of desire and materiality under the conditions of a culture driven by idolization of the celebrity, referring to the works of Jean Baudrillard, Pierre Bourdieu, and French collective Tiqqun. It further examines the events as a moment where (...) subjects were able to escape the life-narratives imposed upon them by the State. Rather than adhering to the norms of regular adolescent life, reproduced and enforced through what Michael Shapiro identifies as “national-time,” members of the Bling Ring endeavored to create their own lives according to what I refer to as “celebrity-time,” revealing processes of becoming in the work of Gilles Deleuze, and plasticity in that of Catherine Malabou.

Phenotypic plasticity, or an organism’s capacity to change its phenotype in response to environmental variation, is a pervasive—perhaps even ubiquitous—feature of the biological world. Accordingly, plasticity research suggests serious implications for biological theory, including evolutionary theory. The theoretical implications of plasticity have growing support from empirical literature documenting the range, extent, and adaptiveness of plasticity. However, the empirical evidence for particular instances of plasticity has still not been adequately scrutinized by biologists or philosophers. After reviewing some important conceptual and theoretical (...) background information, this paper synthesizes some past discussions of the methodology of plasticity studies and provides some novel methodological guidance for plasticity researchers. My conclusion is that not all plasticity studies should carry the same weight: there are patterns we can identify in the features of such studies that should contribute to their credibility. In particular, I argue that some types of organisms and some types of plastic phenotypes are more conducive to the empirical study of plasticity than others. (shrink)

In this article, I explore the relationship betweenperformativity, as it appears in Judith Butler's work, andplasticity, as it appears in the work of Catherine Malabou. I argue that these concepts are isomorphic. Butler and Malabou both hold that resistance to contemporary forms of power, or “insubordination,” is contingent on a subject's ability to become other than what it is; Butler articulates this ability in terms of performativity, and Malabou articulates it in terms of plasticity. I reveal the social-constructivist dimension of (...) Malabou's work while also making apparent the extent to which Butler's work, contrary to her own way of conceptualizing it, and hence surprisingly and uneasily, presupposes a biologically basic capacity for change. Plasticity is this biologically basic capacity. Both thinkers affirm the idea that insubordinate forms of transformation can be impeded by the discourse that conditions what a subject can think. I suggest that this is an insight that must be heeded, even as I seek to affirm a form of plasticity beyond discourse. (shrink)

Kronenfeld's theory, rooted in the tradition of ethnoscience (or cognitive (...) anthropology), accomplishes three things. First, it distinguishes prototypic referents from extended referents. Second, it describes the various bases of semantic extensions. Finally it details how we use the situational context of usage, the linguistic context of opposition and inclusion, and the conceptual context of knowledge about the world to interpret communicative events.

Open peer commentary on the article “A Moving Boundary, a Plastic Core: A Contribution to the Third Wave of Extended-Mind Research” by Timotej Prosen. Abstract: We argue that the free-energy principle (FEP) can indeed be used to articulate a conception of the boundaries of cognitive systems that meets the desiderata of third-wave extended-mind research. We point out that Markov blankets under the FEP definitionally constitute the means through which internal and external states are coupled, and so do not isolate systems (...) from their environment. We argue that the nested, multiscale boundaries of the FEP formulation are indeed plastic and open to re-negotiation. Finally, we appeal to the formulation of niche construction under the FEP to argue that the extension of cognitive boundaries in this formulation is both synchronic and diachronic. (shrink)

One of the most important recent developments in the study of concepts has been the resurgence of interest in nativist accounts of the human conceptual system. However, many theorists suppose that a key feature of neural organization—the brain’s plasticity—undermines the nativist approach to concept acquisition. We argue that, on the contrary, not only does the brain’s plasticity fail to undermine concept nativism, but a detailed examination of the neurological evidence actually provides powerful support for concept nativism.

ABSTRACT Catherine Malabou builds on neuroscience to offer a theory of the plasticity of the brain, arguing that trauma holds transformative potential. This article argues, however, that her theory prioritizes resilience in the face of episodic moments of violence and trauma, which undertheorizes the trauma of chronic conditions experienced by racialized, particularly Black, subjects. Instead, this article turns to Christina Sharpe’s theory of wake work and, more specifically, Black annotation and Black redaction, to demonstrate how, in the wake of transatlantic (...) slavery, there is space for the collective disruption of symbolic structures to generate openings for imagining and circulating alternative possibilities to the hegemonic institutions of the past and present. Contrasting Malabou’s focus on the transformation of the brain during episodic violence and trauma, this article contends that Sharpe may demonstrate the possibility of plasticity in form and the symbolic in quotidian experiences and practices.

A former student and collaborator of Jacques Derrida, Catherine Malabou has generated worldwide acclaim for her progressive rethinking of postmodern, Derridean critique. Building on her notion of plasticity, a term she originally borrowed from Hegel's _Phenomenology of Spirit_ and adapted to a reading of Hegel's own work, Malabou transforms our understanding of the political and the religious, revealing the malleable nature of these concepts and their openness to positive reinvention. In French to describe something as plastic is to recognize both (...) its flexibility and its explosiveness-its capacity not only to receive and give form but to annihilate it as well. After defining plasticity in terms of its active embodiments, Malabou applies the notion to the work of Hegel, Heidegger, Levinas, Levi-Strauss, Freud, and Derrida, recasting their writing as a process of change between dialectic and deconstruction. Malabou contrasts plasticity against the graphic element of Derrida's work and the notion of trace in Derrida and Levinas, arguing that plasticity refers to sculptural forms that accommodate or express a trace. She then expands this analysis to the realms of politics and religion, claiming, against Derrida, that "the event" of justice and democracy is not fixed but susceptible to human action. (shrink)

This article provides an ethnographic account of pediatric cochlear implantation, revealing an important shift in the definition of deafness from a sensory loss to a neurological processing problem. In clinical and long-term therapeutic practices involved in pediatric implantation, the cochlear implant is recast as a device that merely provides access to the brain. The “real” treatment emerges as long-term therapeutic endeavors focused on neurological training. This redefinition then ushers in an ensuing responsibility to “train the brain,” subsequently displacing failure from (...) the device onto the individual’s ability to train his or her brain. New caregiving techniques that accompany implantation are understood through neuropolitics, showing how parents are encouraged to engage in neuro-self-governance, and how the concept of neuroplasticity is used to cultural ends.

A response to Via about the existence (or not) and role of plasticity genes in evolution.

Abstract This paper develops an explanationist treatment of the problem of the criterion. Explanationism is the view that all justified reasoning is justified in virtue of the explanatory virtues: simplicity, fruitfulness, testability, scope, and conservativeness. A crucial part of the explanationist framework is achieving wide reflective equilibrium. I argue that explanationism offers a plausible solution to the problem of the criterion. Furthermore, I argue that a key feature of explanationism is the plasticity of epistemic judgments and epistemic methods. The explanationist (...) does not offer any fixed judgments or methods to guide epistemic conduct; even the explanatory virtues themselves are subject to change. This feature of explanationism gives it an advantage over non-explanationist views that offer fixed epistemic judgments and epistemic methods.

It situates the proliferation of plastic flowers in domestic space within a context of bureaucratic anxieties surrounding natural resource scarcity, and trends toward ‘outdoor living’ that were an offshoot of the ideology of economic growth. Interrogating repeated, if relatively unexamined, invocations of ‘anxious’ suburban subjects in descriptions of postwar society, the essay suggests that plastic flowers shored up a sense of stability and (...) permanence at a time when nuclear annihilation, Cold War paranoia, and population growth combined to render life uncertain and potentially unsustainable. The essay concludes by reflecting on how legacies of that epoch – and the fiction of permanence offered by plastic flowers – endure in contemporary fantasies of limitless progress. (shrink)

There is, according to Maimonides, a redemptive possibility that Aristotle does not recognize. This is based on the fact of revealed law. That is, if there is revealed law, then there is guidance for the (...) ordering of one's dispositions to what is good, even though the individual lacks practical wisdom. There is, in the Maimonidean account, both allowance for more plasticity of character, and at the same time a heightened responsibility for acknowledging what is ethically required. (shrink)
