The question of whether there are laws in ecology is important for a number of reasons. If, as some have suggested, there are no ecological laws, this would seem to distinguish ecology from other branches of science, such as physics. It could also make a difference to the methodology of ecology. If there are no laws to be discovered, ecologists would seem to be in the business of merely supplying a suite of useful models. These models would need to (...) be assessed for their empirical adequacy but not for their ability to capture fundamental truths, or the like. If, on the other hand, ecology does have laws, this prompts further questions about what these laws are and why even the best candidates for ecological laws fall short of what might be expected of laws.

A widely cited roadblock to bridging ecological psychology and enactivism is that the former identifies with realism and the latter identifies with constructivism, which critics charge is subjectivist. A pragmatic reading, however, suggests non-mental forms of constructivism that simultaneously fit core tenets of enactivism and ecological realism. After advancing a pragmatic version of enactive constructivism that does not obviate realism, I reinforce the position with an empirical illustration: Physarum polycephalum (a slime mold), a communal unicellular organism that leaves (...) slime trails that form chemical barriers that it avoids in foraging explorations. Here, environmental building and sensorimotor engagement are part of the same process with P. polycephalum coordinating around self-created, affordance-bearing geographies, which nonetheless exist independently in ways described by ecological realists. For ecological psychologists, affordances are values, meaning values are external to the perceiver. I argue that agent-enacted values have the same status and thus do not obviate ecological realism or generate subjectivism. The constructivist-realist debate organizes around the emphasis that enactivists and ecological theorists respectively place on the inner constitution of organisms vs. the structure of environments. Building on alimentary themes introduced in the P. polycephalum example and also in Gibson’s work, I go on to consider how environment, brain, visceral systems, and even bacteria within them enter perceptual loops. This highlights almost unfathomable degrees of mutually modulating internal and external synchronization. It also shows instances in which internal conditions alter worldly configurations and invert values, in Gibson’s sense of the term, albeit without implying subjectivism. My aim is to cut across the somatic focus of enactive constructivism and the external environment-oriented emphasis of ecological realism and show that enactivism can enrich ecological accounts of value.

This paper argues that it is possible to combine enactivism and ecological psychology in a single post-cognitivist research framework if we highlight the common pragmatist assumptions of both approaches. These pragmatist assumptions or starting points are shared by ecological psychology and the enactive approach independently of being historically related to pragmatism, and they are based on the idea of organic coordination, which states that the evolution and development of the cognitive abilities of an organism are explained by appealing (...) to the history of interactions of that organism with its environment. It is argued that the idea of behavioral or organic coordination within the enactive approach gives rise to the sensorimotor abilities of the organism, while the ecological approach emphasizes the coordination at a higher-level between organism and environment through the agent’s exploratory behavior for perceiving affordances. As such, these two different processes of organic coordination can be integrated in a post-cognitivist research framework, which will be based on two levels of analysis: the subpersonal one and the personal one. If this proposal is on the right track, this may be a promising first step for offering a systematized and consistent post-cognitivist approach to cognition that retain the full potential of both enactivism and ecological psychology.

Axiomatic rationality is defined in terms of conformity to abstract axioms. Savage limited axiomatic rationality to small worlds, that is, situations in which the exhaustive and mutually exclusive set of future states S and their consequences C are known. Others have interpreted axiomatic rationality as a categorical norm for how human beings should reason, arguing in addition that violations would lead to real costs such as money pumps. Yet a review of the literature shows little evidence that violations are actually (...) associated with any measurable costs. Limiting axiomatic rationality to small worlds, I propose a naturalized version of rationality for situations of intractability and uncertainty, all of which are not in. In these situations, humans can achieve their goals by relying on heuristics that may violate axiomatic rationality. The study of ecological rationality requires formal models of heuristics and an analysis of the structures of environments these can exploit. It lays the foundation of a moderate naturalism in epistemology, providing statements about heuristics we should use in a given situation. Unlike axiomatic rationality, ecological rationality can explain less-is-more effects, formalize when one should move from ‘is’ to ‘ought,’ and be evaluated by goals beyond coherence, such as predictive accuracy, frugality, and efficiency. Ecological rationality can be seen as a formalization of means–end instrumentalist rationality, based on Herbert Simon’s insight that rational behavior is a function of the mind and its environment.

Dichotomous definitions of culture and language do not generate productive questions. Instead, more progress can be made by identifying components of each that other animals might plausibly possess. The evolutionary, ecological approach advocated by Rendell and Whitehead holds great promise for helping us to understand the conditions under which natural selection can favor similar capacities in differently organized brains.

A formal theory of the ecological niche is indispensable not only for semantic precision in philosophy to understand and compare it with other meanings of niche, but also when computer scientists and ecologists desire to create interoperable software where one can retrieve the niche of a species and compare their parameters. The proposed model is a more fine-grained description of the ecological niche, including the distinction between its complex concept, the abstract niche (‘fundamental niche’) with its hypervolume in (...) multidimensional space, and its realisations (‘realised niches’). The presented ecological niche may initiate new avenues for research in ecology, particularly concerning the conditions/categories of a hypervolume, as well as further philosophical inquiry and comparison with other niches.

Although it is a common claim in the ecological psychology literature that our perception of the environment’s affordances is influenced by socio-cultural norms, an explanation of how this is possible remains to be offered. In this paper, I outline an account of this phenomenon by focusing on the ecological theory of perceptual learning. Two main theses are defended. First, I argue that to account for how socio-cultural norms can influence perception, we must pay attention not only to the (...) education of attention but to the education of intention too. Consequently, I offer some ideas about how intention can be socio-normatively educated. Secondly, I hold that the education of intention occurs via the acquisition of habit-based preferences for particular actions. I claim that once we understand how these habit-based preferences relate to socio-cultural norms, the hypothesis that norms must be represented in the individual’s mind for them to influence affordance perception is no longer needed. If this hypothesis is on the right track, we can have an explanation for how perception can be normatively shaped and direct (non-mediated by internal representations and inferences) at the same time.

Advanced biological brains are by nature open-ended opportunistic controllers. Such controllers compute, pretty much on a moment-to-moment basis, what problem-solving resources are readily available and recruit them into temporary problem-solving wholes. Neural plasticity, exaggerated in our own species, makes it possible for such resources to become factored deep into both our cognitive and physical problem-solving routines. One way to think about this is to depict the biological brain as a master of what I shall dub ‘ecological control’. Ecological (...) control is the kind of top-level control that does not micro-manage every detail, but rather encourages substantial devolvement of power and responsibility. This kind of control allows much of our skill at walking to reside in the linkages and elastic properties of muscles and tendons. And it allows much of our prowess at thought and reason to depend upon the robust and reliable operation, often in dense brain-involving loops, of a variety of non-biological problem-solving resources spread throughout our social and technological surround. Are the complex distributed systems that result in some sense ‘out of control’, beyond the reach of useful governance? I shall argue that they are not, although understanding them requires us to re-think some key ideas about control and the nature of the self. To make this case, I shall first examine some strategies for efficient, external opportunity exploiting control in simple systems. I shall then argue that many of the same lessons apply to the case of higher-level human problem-solving. (shrink)

According to the paradigm of adaptive rationality, successful inference and prediction methods tend to be local and frugal. As a complement to work within this paradigm, we investigate the problem of selecting an optimal combination of prediction methods from a given toolbox of such local methods, in the context of changing environments. These selection methods are called meta-inductive strategies, if they are based on the success-records of the toolbox-methods. No absolutely optimal MI strategy exists—a fact that we call the “revenge (...) of ecological rationality”. Nevertheless one can show that a certain MI strategy exists, called “AW”, which is universally long-run optimal, with provably small short-run losses, in comparison to any set of prediction methods that it can use as input. We call this property universal access-optimality. Local and short-run improvements over AW are possible, but only at the cost of forfeiting universal access-optimality. The last part of the paper includes an empirical study of MI strategies in application to an 8-year-long data set from the Monash University Footy Tipping Competition. (shrink)

"As a result of human activities, many organisms on Earth face serious and worsening threats to their continued existence. This is usually regarded as a matter of concern because maintaining a healthy non-human environment affects the well-being of humans.

Ecological feminism is the position that there are important connections-historical, symbolic, theoretical-between the domination of women and the domination of nonhuman nature. I argue that because the conceptual connections between the dual dominations of women and nature are located in an oppressive patriarchal conceptual framework characterized by a logic of domination, (1) the logic of traditional feminism requires the expansion of feminism to include ecological feminism and (2) ecological feminism provides a framework for developing a distinctively feminist (...) environmental ethic. I conclude that any feminist theory and any environmental ethic which fails to take seriously the interconnected dominations of women and nature is simply inadequate. (shrink)

Explaining agency is a significant challenge for those who are interested in the sciences of the mind, and non-representationalists are no exception to this. Even though both ecological psychologists and enactivists agree that agency is to be explained by focusing on the relation between the organism and the environment, they have approached it by focusing on different aspects of the organism-environment relation. In this paper, I offer a suggestion for a radical embodied account of agency that combines ecological (...) psychology with recent trends in enactive cognitive science. According to this proposal, while enactivism focuses primarily on describing how our acquired sensorimotor schemes and habits mutually equilibrate, affecting our tendency to act upon some affordances instead of others, ecological psychology focuses on studying how perceptual information contributes to the actualization of the sensorimotor schemes and habits without mediating representations, inferences, and computations. The paper concludes by briefly exploring how this ecological-enactive theory of agency can account for how socio-cultural norms shape human agency. (shrink)

This article draws on the ecological model of teacher agency and elaborates on how teacher agency is achieved, its components and how it could be strengthened. This model highlights professional competence, structural and cultural context, and professional purpose as the main elements of achieving agency. In this paper, we specify some elements of the ecological model and elaborate on how three types of reflection could be used to strengthen conditions for achieving teacher agency. These include, first, procedures aimed (...) at articulating the theory of action, including effective strategies, rules and principles for practice; second, procedures of practical reflection, aimed at fostering the conceptualization of practice and the understanding of oneself as a teacher; and third, procedures of critical reflection, which help to address the inequalities and malpractices of education and society. The main importance of this paper is to extend the practical relevance of the ecological model for teacher learning settings. (shrink)

This paper argues that the language of rights cannot express distinctively ecofeminist insights into the treatment of nonhuman animals and the environment. An alternative is proposed in the form of a politicized ecological ethic of care which can express ecofeminist insights. The paper concludes with consideration of an ecofeminist moral issue: how we choose to understand ourselves morally in relation to what we are willing to count as food. "Contextual moral vegetarianism" represents a response to a politicized ecological (...) ethic of care. (shrink)

This article examines how a non-anthropocentric virtue ethics can truly avoid an anthropocentric bias in the ethical evaluation of a situation where the environment is at stake. It argues that a non-anthropocentric virtue ethics capable of avoiding the pitfall of an anthropocentric bias can only conceive of the ultimate good—from which virtues are defined—in reference to an ecological self. Such a self implies that the natural environment is not simply a condition for human flourishing, or something that complements it (...) by adding the proper good of animals, organisms or ecosystems. Fulfilment is not that of a human self, but that of an ecological self: the natural environment or nature is not an external but an internal good. Therefore, the virtues or character traits that such an ecological self must nurture and develop leads us ultimately to distinguish—without opposing them—three different forms of virtue ethics applied to the environment, depending on whether it is anthropocentric or non-anthropocentric and whether nature is considered extrinsically or intrinsically. Such distinctions are also crucial to determine how we conceive of the political community and the collective goals that virtuous citizens assign to it (for instance, to preserve biodiversity, to tackle climate change, and so on).

Philosophy of science has undergone a naturalistic turn, moving away from traditional idealized concerns with the logical structure of scientific theories and toward focusing on real-world scientific practice, especially in domains such as modeling and experimentation. As part of this shift, recent work has explored how the project of philosophically understanding science as a natural phenomenon can be enriched by drawing from different fields and disciplines, including niche construction theory in evolutionary biology, on the one hand, and ecological and (...) enactive views in embodied cognitive science, on the other. But these insights have so far been explored in separation from each other, without clear indication of whether they can work together. Moreover, the focus on particular practices, however insightful, has tended to lack consideration of potential further implications for a naturalized understanding of science as a whole (i.e., above and beyond those particular practices). Motivated by these developments, here we sketch a broad-ranging view of science, scientific practice and scientific knowledge in terms of ecological-enactive co-construction. The view we propose situates science in the biological, evolutionary context of human embodied cognitive activity aimed at addressing the demands of life. This motivates reframing theory as practice, and reconceptualizing scientific knowledge in ecological terms, as relational and world-involving. Our view also brings to the forefront of attention the fundamental link between ideas about the nature of mind, of science and of nature itself, which we explore by outlining how our proposal differs from more conservative, and narrower, conceptions of “cognitive niche construction.”.

I argue that fitting resentment tracks unacceptable ‘ecological’ imbalances in relative social strength between victims and perpetrators that arise from violations of legitimate moral expectations. It does not respond purely, or even primarily, to offenders’ attitudes, and its proper targets need not be fully developed moral agents. It characteristically involves a wish for the restoration of social equilibrium rather than a demand for moral recognition or good will. To illuminate these contentions, I focus on cases that I believe demonstrate (...) a corollary thesis, namely, that strength, broadly construed, is a necessary condition of resentment-worthiness. I argue that weakness can make resentment unfitting in two ways. First, weakness may prevent a wrongdoer from shifting the balance of social power. Second, a weak wrongdoer may do social damage but be so lowly that resentment, which would represent him as excessively strong, would be inapt. Finally, I consider how accepting the ecological view might affect our theorizing about moral responsibility and the ethics of blame. (shrink)

This paper focuses on tacit versus explicit uses of plural performance metrics as a primary methodological characteristic. This characteristic usefully distinguishes two schools of normative analysis and their approaches to normative interpretations of bounded rationality. Both schools of thought make normative claims about bounded rationality by comparing the performance of decision procedures using more than one performance metric. The consistency school makes tacit reference to performance metrics outside its primary axiomatic framework, but lexicographically promotes internal axiomatic consistency as the primary, (...) and in most cases sufficient, normative outcome with which to undertake welfare comparisons. The consistency school's axiomatization program, in both neoclassical and behavioral forms, pre-commits to welfare interpretations that follow a hierarchy of rationalities based on the stringency of restrictions that different axiomatizations impose on choice data. In contrast, the ecological rational.. (shrink)

An extension of Alasdair MacIntyre's concept of 'virtues of acknowledged dependence', to include relationships with the non-human world, offers an organising principle for environmental virtue ethics. It situates ecological virtue among more traditional virtues of inter-human relationships, and may thereby contribute to an ethical reconciliation of policies aimed at encouraging ecological virtue with those aimed at protecting the freedoms required for personal autonomy. Within this eudaimonist framework, ecological virtue may be understood and promoted as directly contributing to (...) a good life. (shrink)

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: This commentary highlights some controversial aspects of enactivism and ecological psychology, specifically the notions of subjectivity and ecological information.

This article presents a developmental ecological approach to the emergence and development of metaphor in children, based on the ecological psychology tradition following the work of J.J. Gibson, and its extension into developmental research and theory, as developed by E.J. Gibson and others. This framework suggests that a basic compatibility and meaningfulness exists between the knower and the known, based on the direct perception of affordances. To build an ecological understanding of metaphor we need to clarify how (...) this metaphysical ground plays out in acts of knowing that involve metaphor. In this endeavor, it is important to understand the ontogenesis of novel insightful metaphors and the role of perception. Developmental ecological psychology has repeatedly shown that infants can perceive meta-modal invariants that specify persistence of qualities. Early metaphors are consequences of the process in which invariants over naturally occurring kinds are perceived. Thus, novel metaphor production is an act of situated and experience-dependent perceiving and acting in the ecological world of socially shared meanings. Examples from previous experimental and qualitative research are reviewed to substantiate theoretical claims. (shrink)

In this paper I distinguish various ways in which empirical claims about evolutionary and ecological models can be supported by data. I describe three basic factors bearing on confirmation of empirical claims: fit of the model to data; independent testing of various aspects of the model, and variety of evident. A brief description of the kinds of confirmation is followed by examples of each kind, drawn from a range of evolutionary and ecological theories. I conclude that the greater (...) complexity and precision of my approach, as compared to, for instance, a Popperian approach, can facilitate detailed analysis and comparison of empirical claims.

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: The authors of the target article seem on the one hand to want to reprimand enactivists for not embracing ecological psychology, and on the other, to criticise them for taking on board some - but not all - of the principles of ecological psychology. In this commentary, I argue that the claim that enactivists have not embraced (...) class='Hi'>ecological psychology is false, and that it is coherent for enactivists to take on only some of the principles of ecological psychology, as the two research frameworks have different overall projects. Furthermore, I argue that there is an enactivism-friendly stream of ecological psychology research that is currently yielding exciting results that both broaden the depth of ecological psychology research and bring it into dialogue with enactivism-inspired approaches to understanding perception and experience.

In the debate around ecological democracy, a pivotal point of contention has long been the question why democracy should actually be expected, as some claim, to deliver (more) ecological outcomes. This point is empirical as well as conceptual: it is difficult to conceive why voters would support any policies that - as is often (perceived to be) the case with environmental legislation - would leave them worse off; whilst democracy conceptually must remain open to all outcomes rather than (...) being tied to any particular agenda ex ante. Yet both empirically and conceptually, the nature and extent of this key puzzle has always hinged on the particular definitions used. This paper reconsiders the link between democracy and ecological sustainability from a cultural angle: I argue that conceiving of both sustainability and democratisation as essentially cultural transformations resolves the puzzle and thus makes a renewed case for ecological democracy. Only as cultural processes - the creation of new meanings of sustainable prosperity in people's everyday lives, and a culturally rather than institutionally based form of democratisation - can these transformations be deep-seated rather than superficial, and thus self-perpetuating rather than merely enforced.

In the twentieth century, philosophy (especially within the United States) embraced the notion of disciplinary expertise: philosophical research consists of working with and writing for other philosophers. Projects that involve non-philosophers earn the deprecating title of “applied” philosophy. The University of North Texas (UNT) doctoral program in philosophy exemplifies the possibility of a new model for philosophy, where graduate students are trained in academic philosophy and in how to work with scientists, engineers, and policy makers. This “field” (rather than “applied”) (...) approach emphasizes the inter- and transdisciplinary nature of the philosophical enterprise where theory and practice dialectically inform one another. UNT’s field station in philosophy at Cape Horn, Patagonia, Chile is one site for developing this ongoing experiment in the theory and practice of interdisciplinary philosophic research and education.

This paper discusses Millstein’s criticism of the consensus view formed against selected-effects ecological functions. I argue that Millstein’s defense of coevolution-based selected-effects ecological functions applies to a notion of function as an activity, whereas proponents of the consensus view are concerned with a notion of ecological function as the contribution of an organism, population, species, or abiotic item to the maintenance of its community and/or the functioning of its ecosystem. Millstein’s arguments hence do not invalidate the consensus (...) view but draw attention to a notion of function that has been neglected in philosophical discussions and that deserves more attention.

This paper addresses the question whether we can conceive of music cognition in ecosemiotic terms. It claims that music knowledge must be generated as a tool for adaptation to the sonic world and calls forth a shift from a structural description of music as an artifact to a process-like approach to dealing with music. As listeners, we are observers who construct and organize our knowledge and bring with us our observational tools. What matters is not merely the sonic world in (...) its objective qualities, but the world as perceived. In order to make these claims operational we can rely on the ecological concept of coping with the sonic world and the cybernetic concepts of artificial and adaptive devices. Listeners, on this view, are able to change their semantic relations with the sonic world through functional adaptations at the level of sensing, acting and coordinating between action and perception. This allows us to understand music in functional terms of what it affords to us and not merely in terms of its acoustic qualities. There are, however, degrees of freedom and constraints which shape the semiotization of the sonic world. As such we must consider the role of event perception and cognitive economy: listeners do not perceive the acoustical environment in terms of phenomenological descriptions but as ecological events.

The problem we face today is that there is a huge gap between our ethical judgments about the ecological crisis on the one hand and our ethical behavior according to these judgments on the other. In this article, we ask to what extent a phenomenology of the ecological crisis enables us to bridge this gap and display more ethical or pro-environmental behavior. To answer this question, our point of departure is the affordance theory of the American psychologist and (...) founding father of ecological psychology, James Gibson. There are two reasons for taking this approach. First of all, an ontological reading of Gibson’s affordance theory provides a concept of nature which is non-dualistic, non-anthropocentric and eco-centric, but is not seen as an ‘intrinsic value’ or product of ‘human valuation’. Secondly, the affordance ontology provides us with a concept of nature which in itself calls for certain action and behavior. If we indeed face a gap between ethical judgment and ethical behavior with regard to the current ecological crisis, an affordance of nature could bridge this gap. Based on our ontological reading of Gibson’s affordance theory, we open a radically new perspective on the current ecological crisis and the responsibility of mankind with regard to this crisis.

In the Anthropocene, the fact that human activity is enmeshed with the existence and actions of every kind of other being is inescapable. As a result, the planetary ecological crisis has brought forth an urgent need to rethink understandings of human action. One response holds that the transformations necessary to tackle today’s crises will emerge from the distinctive capacity of human beings to transcend their environment. Another school of thought calls for seeing action as composite, produced by distributed networks (...) of human and nonhuman agents. Yet the first of these is open to charges of human exceptionalism, while the second, according to its critics, lacks effective political traction. Martin Crowley argues that a new conception of political agency is necessary to break this impasse. Engaging with thinkers such as Bruno Latour, Bernard Stiegler, and Catherine Malabou, Crowley proposes an original account of agency as both distributed and decisive. Challenging the prevailing view of agency as exclusively human, he explores how a politics that incorporates nonhuman agency can intervene in the real world, examining timely issues such as climate-related migration and digital-algorithmic politics. A major intervention into ongoing debates in posthumanism, political ecology, and political theory, Accidental Agents reshapes our understanding of political agency in and for a more-than-human world.

Within the last 20 years, the US has mounted amassive campaign against invasions bynon-indigenous species (NIS) such as zebramussels, kudzu, water hyacinths, and brown treesnakes. NIS have disrupted native ecosystemsand caused hundreds of billions of dollars ofannual damage. Many in the scientificcommunity say the problem of NIS is primarilypolitical and economic: getting governments toregulate powerful vested interests thatintroduce species through such vehicles asships' ballast water. This paper argues that,although politics and economics play a role,the problem is primarily one of scientificmethod. (...) Even if commercial interests werewilling to spend the necessary funds to controlNIS, and even if government were willing toregulate them, ecological theory is notadequate to provide clear direction for eithereffort. The paper argues there is nocomprehensive, predictive theory ofinvasibility, as part of a larger theory ofcommunity structure, that might guideecological decision making regarding NIS, andfor at least three reasons. (1) There is nofirm definition of NIS, native, exotic,and so on, and ecologists do not use the termsconsistently; as a result, biologists debatingvarious accounts of community structure andecological explanation often do not even makelogical contact with each other. (2) Thedominant theory used to understandinvasibility, island biogeography, has noprecise predictive power and is unable toclarify when NIS might promote biodiversity andwhen they might hinder it. (3) There are nofirm, empirical generalizations that revealwhen a colonizer or a NIS might be likely totake over a new environment, and when it mightnot succeed in doing so. As a result,scientists have only rough rules of thumb toshore up their arguments against NIS. Given theincompleteness of current ecological theory,the paper closes with several suggestions forways that study of NIS might enhanceunderstanding of basic commmunity structuresand vice versa.

Green Mass is a meditation on—and with—twelfth-century Christian mystic and polymath Saint Hildegard of Bingen. Attending to Hildegard's vegetal vision, which greens theological tradition and imbues plant life with spirit, philosopher Michael Marder uncovers a verdant mode of thinking. The book stages a fresh encounter between present-day and premodern concerns, ecology and theology, philosophy and mysticism, the material and the spiritual, in word and sound. Hildegard's lush notion of viriditas, the vegetal power of creation, is emblematic of her deeply entwined (...) understanding of physical reality and spiritual elevation. From blossoming flora to burning desert, Marder plays with the symphonic multiplicity of meanings in her thought, listening to the resonances between the ardency of holy fire and the aridity of a world aflame. Across Hildegard's cosmos, we hear the anarchic proliferation of her ecological theology, in which both God and greening are circular, without beginning or end. Introduced with a foreword by philosopher Marcia Sá Cavalcante Schuback and accompanied by cellist Peter Schuback's musical movements, which echo both Hildegard's own compositions and key themes in each chapter of the book, this multifaceted work creates a resonance chamber, in which to discover the living world anew. The original compositions accompanying each chapter are available free for streaming and for download at www.sup.org/greenmass. (shrink)

The notion of ecological civilisation has become central to Chinese efforts to confront and deal with environmental problems. However, ecological civilisation is characterized by its proponents in different ways. Some see it as simply an adjunct to the existing system designed to deal with current ecological crises. Its more radical proponents argue for a socialist ecological civilisation that should be developed globally and transform every part of society, changing the way people perceive, live and relate to (...) each other and to nature, and the goals they aspire to. Ecological civilisation is a translation of the Russian notion of ecological culture, and tracing the history of ecology and the concept of culture in the Soviet Union, particularly in the 1920s, I will support this more radical view, arguing that ecological civilisation is not only underpinned by eco-socialism; it provides the means to clarify the meaning of socialism generally in a way that accords with deep assumptions of Marx’s critique of capitalism. That this notion has been officially embraced within China establishes a tradition of socialist thought that now has the potential to challenge and replace global capitalism. (shrink)

In this paper, I develop an ecological-enactive perspective on the role rules play in linguistic behaviour. I formulate and motivate the hypothesis that metalinguistic reflexivity – our ability to talk about talking – is constitutive of linguistic normativity. On first sight, this hypothesis might seem to fall prey to a regress objection. By discussing the work of Searle, I show that this regress objection originates in the idea that learning language involves learning to follow rules from the very start. (...) I propose an ecological-enactive response to the regress objection. The key move is to deny that language learning consists initially in learning rules. A child first engages in regular communicative behaviour, by learning first-order linguistic skills, and then retroactively interprets her own behaviour in normative metalinguistic terms, i.e., as being guided by rules by relying on reflexive or second-order linguistic skills. On this view, metalinguistic reflexivity enables regulation of already regular communicative behaviour, and thereby constitutes linguistic normativity. Finally, I argue that linguistic rules are resources: they are available to participants in order to (re)negotiate properties of situated language behaviour and thereby reorganize linguistic practices. The account developed in this paper thus allows us to understand the constitutive role of metalinguistic reflexivity for linguistic normativity without falling prey to the regress objection. (shrink)
