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)

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 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 (...) class='Hi'>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 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.

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.

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)

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.

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 convincing argument that Brette makes for the neural coding metaphor as imposing one view of brain behavior can be further explained through discourse analysis. Instead of a unified view, we argue, the coding metaphor's plasticity, versatility, and robustness throughout time explain its success and conventionalization to the point that its rhetoric became overlooked.

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.

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.

Agriculture is a serious contributor to pollution and other environmental harms, making it an important site of action for the development of environmentally friendly products and practices. However, farmer adoption of such options is varied and dependent on a wide range of factors including the visual appeal of sustainable farming. Recent studies have shown that negative aesthetics related to more environmentally friendly ways of farming can delay or prevent adoption of such practices. Drawing on the concepts of good farming, cultural (...) capital, and the aesthetics of waste, this paper aims to assess the status of biodegradable plastic mulch in relation to a range of alternative and conventional specialty crop growers’ aesthetic perceptions. BDM has the potential to significantly reduce non-biodegradable polyethylene mulch waste, thus addressing serious environmental and human health concerns. However, the aesthetics of BDM may present a challenge. BDM looks identical to PE plastic, and its degradation throughout the season results in scraps in the soil. To investigate aesthetics as a possible barrier to BDM adoption, we conducted five photo-elicitation focus groups with specialty crop growers in Washington State. Results indicate that alternative growers are slightly more adverse to the aesthetics of BDM, especially because of its ‘plastic’ appearance. Conventional growers had higher rates of BDM adoption, even though they felt a strong aesthetic aversion to the messy nature of BDM degradation. Confidence in the product, particularly as a result of education and experience, was believed to be the key to overcoming this negative aesthetic. Study participants offered a variety of ways to enhance the acceptability of BDM, such as making the mulch brown instead of black. These findings have wider implications for the acceptance and adoption of practices that, although environmentally friendly, have an unattractive visual element. (shrink)

Philosophy & Social Criticism, Volume 48, Issue 8, Page 1140-1173, October 2022. 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)

What form might truth take in a theoretical frame which precludes notions of origin and telos? Catherine Malabou’s theory of ‘plasticity’ is such a frame, as it takes the accumulation of life and not the search for eternal truths to be a central premise of philosophy. I conduct a close reading of central texts of Malabou’s to conceptualise truth as a plastic phenomenon over three stages: conception, gestation, and nativity. The conception of truth involves its coming-into-shape; gestation its consolidation (...) of shape; nativity the precariousness of being alive. ‘Plastic truth’ represents a meeting of negotiations, accidents, history, and morality, in constant motion; an epistemic modality with moral and political consequences for education.

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)

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.

The paper describes the context and the origin of a particular debate that concerns the evolution of phenotypic plasticity. In 1965, British biologist A. D. Bradshaw proposed a widely cited model intended to explain the evolution of norms of reaction, based on his studies of plant populations. Bradshaw’s model went beyond the notion of the “adaptive norm of reaction” discussed before him by Dobzhansky and Schmalhausen by suggesting that “plasticity” the ability of a phenotype to be modified by (...) the environment should be genetically determined. To prove Bradshaw’s hypothesis, it became necessary for some authors to identify the pressures exerted by natural selection on phenotypic plasticity in particular traits, and thus to model its evolution. In this paper, I contrast two different views, based on quantitative genetic models, proposed in the mid-1980s: Russell Lande and Sara Via’s conception of phenotypic plasticity, which assumes that the evolution of plasticity is linked to the evolution of the plastic trait itself, and Samuel Scheiner and Richard Lyman’s view, which assumes that the evolution of plasticity is independent from the evolution of the trait. I show how the origin of this specific debate, and different assumptions about the evolution of phenotypic plasticity, depended on Bradshaw’s definition of plasticity and the context of quantitative genetics.

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.

In the developing and adult cortex, just as in the adult hippocampus, LTP is unable to account for a variety of types of functional plasticity.

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.

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. In this short paper, I respond to Lee. I argue, first, that, on the most popular theories of personal identity, zygotic plasticity does not undermine conceptionism, and, second, that, even overlooking this first issue, Lee’s plasticity argument is problematic. My goal in all of this is not to take a stand (...) in the abortion debate, which I remain silent on here, but, rather, to push for the conclusion that transitivity fails when we are talking about numerical identity of non-abstract objects.

Most discussions of neural plasticity in the context of the Molyneux question focus on changes in the visual cortex, early on during critical periods, or post-surgery after patients are given sight. There are good reasons, based on enactive approaches to perception to ask about plastic changes in the dorsal visual pathway and motor control areas. This essay explores the implications of such changes for the Molyneux question.

This book is an interdisciplinary study of the cultural representations of Jesus in the context of contemporary religious theory and continental philosophy. It looks at Jesus in view of an updated Derridean hauntology and spectrality, with an emphasis on the inherent plasticity of the Christian heritage. While the work engages with the recent Jesus-centered writings of Slavoj Žižek, François Laruelle, and Giorgio Agamben, it places a greater and much needed emphasis on the philosophical, theological, and cultural links between a (...) plastic, hauntological Christian heritage and Jesus's historically evolving plural subjectivity, with the latter explored in texts of popular culture. It is a multidisciplinary study of Jesus, as well as a dynamic Christian heritage that simultaneously constructs and deconstructs Jesus's philosophical, political, and cultural centrality. (shrink)

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.

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)

Hyperplasia and hypertrophy are elements of phenotypic plasticity adjusting organ size and function. Because they are costly, we assume that they are beneficial. In this review, the authors discuss examples of tissue and organ systems that respond with plastic changes to osmotic stress to raise awareness that we do not always have sufficient experimental evidence to conclude that such processes provide fitness advantages. Changes in hydranth architecture in the hydroid Cordylophora caspia or variations in size in the anal papillae (...) of insect larvae upon changes in medium salinity may be adaptive or not. The restructuring of salt glands in ducklings upon salt‐loading is an example of phenotypic plasticity which indeed seems beneficial. As the genomes of model species are recently sequenced and the animals are easy to rear, these species are suitable study objects to investigate the biological significance of phenotypic plasticity and to study potential epigenetic and other mechanisms underlying phenotypic changes.

Ghosh introduces the term 'plastic turn' and gives a new direction for how we can interpret and experience the turn today.

This essay argues that the reigning medical and scientific understanding of the endocrine system, which insists on its fundamental biological plasticity, was historically constructed through a dual child–animal metaphor. The work accomplished by such organic metaphors, as Donna Haraway terms them, returns us to the endocrine laboratories and clinics in which they were built in Europe and the United States in the first half of the twentieth century. The child and animal metaphors implanted the concept of plasticity into (...) the human body to the effect of bringing sexed and gendered life under the jurisdiction of science and medicine, where it could not only be normalized in a sense long appreciated by transgender studies but also cultivated towards the ostensible “improvement” and “perfection” of the human. This is also, then, a history of the eugenic heritage of modern endocrinology, which has been largely ignored in recent discussions of plasticity and the body’s materiality. To interrogate the role of foundational organic metaphors in endocrinology is to open up plasticity not only to its historical context but also to radical contestation, making the contemporary assumptions of transgender medicine untimely, particularly the medicalization of the transgender child.

I present—in an extremely sketchy form—a model of two-level, open, plastic and multidimensional human nature. Due to the included attribute of multidimensionality this model opposes the reductive conceptions of man dominating in today’s philosophy. The main objective of the paper is the ontological status of man, especially the ontic foundation of multidimensional man. I demonstrate that this status remains a riddle; one only knows that from the ontological perspective man is a wholly exceptional object, not explainable by to-date ontological constructions.

The article discusses fascinating points of similarity and difference between Leibniz's Monadology and Heidegger's 'The Thing', two of the greatest short works in the history of philosophy. But the key point of intersection between them is not widely recognised: indirect causation.

The “puzzle” of emotional plasticity concerns making sense of two conflicting bodies of evidence: evidence that emotions often appear modular in key respects, and evidence that our emotions also often appear to transcend this modularity. In this paper, I argue a developmentalist approach to emotion, which builds on Karmiloff-Smith’s (1986, 1992, 1994, 2015) work on cognitive development, can help us dissolve this puzzle.

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)

Drawing on Catherine Malabou’s notion of plasticity, this article argues for a conception of resilience as plastic. Resilience has proven an important concept in health care, describing how we manage life-changing illnesses. Yet, resilience is not without its critics, who suggest it neglects a political, social, or personal dimension in illness. In this article, I propose that a concept of plastic resilience can address these criticisms. On this account, success should not be based on a return to function, but (...) rather on how actively we are involved in the formation of a new self after illness. I address some approaches that can benefit from “plastic resilience,” namely, art therapy, expert companionship, and shared decision-making. In each case, I underline how we should help patients thematize and engage with their new selves, while also being constantly vigilant for how these changes might impact our current assumptions around their preferences for treatment.

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.

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)

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 lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Plastic Turn by Ghosh, RanjanMaria MargaroniGhosh, Ranjan. The Plastic Turn. Cornell University Press, 2022. 224pp.In Plasticity at the Dusk of Writing: Dialectic, Destruction, Deconstruction (2005; 2010), Catherine Malabou argues that “the concept of plasticity is becoming both the dominant formal motif of interpretation and the most productive exegetical and heuristic tool of our time,” supplanting older theoretical paradigms such as “writing” and “the trace” (57). (...) Almost twenty years later, the truth of this statement is certainly confirmed not only by Malabou’s own developing elaboration of this concept and the growing body of works inspired by her creative adaptation of neurological theory in the realm of philosophy, but also by the proliferation of studies that seek to reflect on the ecological, anthropological, ethical, or political consequences of what has been termed the “Plasticene.”1 There is no doubt, then, that we are witnessing yet another “turn” in the Humanities and Social Sciences, the plastic turn coming to displace or supplement a host of currently competing theoretical tendencies: i.e., the material turn, the affective turn, the cognitive turn, and the mimetic turn, among others.2Ranjan Ghosh’s The Plastic Turn is the first in a trilogy intended to theorize the aims, scope and effects of a “plastic Humanities.”3 Interestingly, Ghosh does not locate the “turn” in the 1990s when plastic “gained widespread public acceptance” (Mah 31) and when (with the development of the neurosciences) brain plasticity was increasingly adopted as “the most effective sensor of energy and meaning” of our contemporary era (Malabou, Plasticity 31-32). Instead, he goes back to the turn of the twentieth century when plastic as a new material and plasticity as a scheme of thought were still in the realm of potentiality, triggering, countering, and reshaping many of our political, cultural, and aesthetic modern imaginaries.Much has been written about the promise of plastic as a “magical” substance, capable of sublimating matter into what Roland Barthes describes as the trace of a metamorphic movement that produces an abundance of forms out of the singularity of its origin (104-105). In “The Material Consciousness of Plastics,” Russell Gagg notes that “in the early part of the twentieth century, plastics were seen as leading a new utopian vision for economic growth after the depression of the pre-war and austerity of the post-war years” (32). In the interwar period, plastics were [End Page 149] promoted for their democratic, egalitarian potential in making “designed consumer goods […] commercially viable,” thus introducing an aesthetics of the popular and the banal (Gagg 44-45; Ghosh 9, 20). One of the many strengths of Ghosh’s book is that it takes inspiration not merely from plastic as the stuff of fantasy but also from the very materiality of plastic, namely, its polymeric structure, malleability of form, sensitivity to the change of temperature, crystalline-amorphous texture, diverse modes of esterification, and resistance to biodegradability. In his first chapter, Ghosh acknowledges the influence of Goethe’s Elective Affinities and Primo Levi’s The Periodic Table which, as he argues, bring “the chemical metaphor to bear on human relationships” (20). He points to the development of a body of contemporary works that elaborate a “chemo-poetics,” aiming to “connect life and its undulations with molecular formations” (21).4 In subsequent chapters, the author succeeds in re-molding the chemical metaphor exploited in these works into a full-blown “material-aesthetic” that enables him to produce new readings of the forces behind literary modernism; the possibilities, limits, and stakes of world literature; the emergence of uncanny forms of plastic nature and art; and the distinct affective modalities caused by our petro-modernity.In analyzing side-by-side the diverse histories of, on the one hand, plastic as an increasingly disgraced material and, on the other hand, our literary, aesthetic, and critical production from the early 20th century to the present, Ghosh is dependent on an analogical process that permits him to think across multiple disciplines and subjects, connecting terms, ideas, and practices that resonate but remain asymmetrical (1). As he emphasizes, it is the “asymmetrically analogous (metaphors)” that “deepens the framework of my arguments” (3). Indeed... (shrink)

The theorizing of utopia is a persistent theme throughout several generations of the French continental tradition, and alongside the process theory of Alfred North Whitehead to a large degree recuperates the concept of utopia from its supposed dismissal by Marx and his intellectual descendants. Most recently, attention to the notion of plasticity, popularized by Catherine Malabou, extends speculation on utopian possibility. Compelled to answer to Marx’s denigration of utopia as fantasy, the tendency was to compensate for the absence of (...) a programmatic politics by stressing what is “useful” about utopian dreaming, and therefore where or how exactly a utopian text reveals or creates political drive, or motivates political action. In this essay, I argue that theorists have overlooked the use of utopia as not only the reproduction of difference, or what Malabou calls positive plasticity, but also as, therefore, a disruption; Malabou might prefer the term accident here. Tracing the concept of plasticity from Roland Barthes to Malabou, with a nod at Miguel Abensour, this essay teases out the links between a contemporary notion of plasticity to argue, simply put, that utopia is plastic. This plasticity of the concept ensures its political force. These links, obscured in the essay “Plastic,” Barthes makes only later in his writing. But for Malabou, plasticity underlies a principle of futurity and/as generativity, such that new forms, new meanings, new concepts emerge through difference. Utopia’s horizons of potentiality depend on difference, and on non-achievement. Finally, I argue that the persistence of utopia as a form of thinking is the most important, and political, effect of utopian plasticity. (shrink)

In the early twentieth century, the body was seen as both an ontogenetic and a phylogenetic entity. In the former case, its individual development, it was manifestly changeable, developing from embryo to maturity and thence to a state of decay. But in the latter case, concerning its development as a species, the question was an open one. Was its phylogenetic nature a stationary snapshot of the slow process of evolution, or was this too mutable? Historians have emphasised that the question (...) of acquired inheritance remained open into the twentieth century; this paper explores how various constructions of the individual as a phylogenetic episode—a stage in the race’s evolution—related to representations of the body in the same period.A discussion of the work of the brothers Josef and Karel Čapek offers a contextualised answer to the question of bodily representation. Karel Čapek explored the nature of the ‘average man’ through two different organisms, the robot and the amphibian, epitomes respectively of corporeal permanence and plasticity. Josef Čapek , along with other members of the Group of Plastic Artists, explored visual representations of the body that challenged cubist Bergsonian norms. In so doing, he affirmed what his brother also held: that despite the constrictions imposed by the oppressive political conditions in which the Czechs found themselves, the individual body was a fragile but fluid entity, capable of effecting change upon the future evolution of humankind.

A career-spanning collection of published and unpublished writings from one of today's leading French philosophers 25 essays showcase Malabou's rounded philosophical project: 17 previously published and 8 brand newDemonstrates the interdisciplinary range and expansive applicative scope of her concept of plasticity Presents a full portrait of Malabou's philosophy which shows her project as a coherent conceptual problem rather than a collection of disparate topics and themesIncludes a critical introduction by Malabou expert Ian JamesCatherine Malabou is one of the foremost, (...) most innovative intelligences working in contemporary French philosophy today. Her work articulates a coherent conceptualisation of 'plasticity' by merging recent neurobiology and medicinal sciences with the history of philosophy and political theory.Across the essays gathered in Plasticity: The Promise of Explosion, Malabou carves a philosophical space between structuralism, deconstruction, cognitive psychology, psychoanalysis and speculative realism. By demonstrating the plastic transformability at the heart of these disciplines, a change that always promises future explosion, Malabou, as a female philosopher, also articulates the need to 'change difference' within patriarchal concepts of tradition itself.The collection is divided into four thematic parts, each of which showcases a major aspect of Malabou's conceptualisation of plasticity. In his introduction, Ian James situates Malabou's work within contemporary philosophy and navigates the contours of her unique work.--Back cover. (shrink)

Drawing on the narratives of young lower-middle-class women employed in cafés, call centers, shopping malls, and offices in Delhi, India, in this paper I identify malleability or “plasticity” of the body as an important feature of contemporary service work. As neophyte service professionals, young women mold themselves to the middle-/upper-class milieu of their workplaces through clothes, makeup, and body language. Such body plasticity can be experienced as enabling: Identifying with the image of the “New Indian Woman,” young women (...) enter the bourgeoning service economy. However, they also experience this body plasticity as threatening; bodily changes to meet the requirements of work can, at times, feel inauthentic as well as be read as promiscuous by others. I draw attention to how women appraise plastic bodies as both generative of change and a site of labor discipline, thus offering insights into the relationship among bodies, social inequalities, and contemporary service work.

The study of phenotypic plasticity has progressed significantly over the past few decades. We have moved from variation for plasticity being considered as a nuisance in evolutionary studies to it being the primary target of investigations that use an array of methods, including quantitative and molecular genetics, as well as of several approaches that model the evolution of plastic responses. Here, I consider some of the major aspects of research on phenotypic plasticity, assessing where progress has been (...) made and where additional effort is required. I suggest that some areas of research, such the study of the quantitative genetic underpinning of plasticity, have been either settled in broad outline or superseded by new approaches and questions. Other issues, such as the costs of plasticity are currently at the forefront of research in this field, and are likely to be areas of major future development. (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.

Peirce’s architectonics, far from rigid, is bended by many plastic transformations, deriving from the cenopythagorean categories, the pragmaticist (modal) maxim, the logic of abduction, the synechistic hypotheses and the triadic classification of sciences, among many other tools capable of molding knowledge. Plasticity, in turn, points to interlacements between mathematics and art, and shapes some associated conceptual forces in the boundary of the disciplines: variation, modulation and invariance; transformability, continuity and discreteness; creative emergence. In this article we focus on this (...) third aspect, through bounded, well defined case studies in the Logic Notebook. The first section describes the manuscript and its interest for a study of creativity, leading to a short speculation on “creative reason” and “plastic imagination” in Peirce. The second section studies five precise cases of creative emergence in the Logic Notebook: differential relatives, existential graphs, sequence diagrams, triadic logic, translatability. Some major surprises occur in those detailed studies. (shrink)
