I examine the use of the term function in Aldo Leopold’s land ethic, invoked as (1) the healthy functioning of the land community, which is dependent on (2) the maintenance of the characteristic functions of populations that are parts of the land community. The latter can be understood as referring to interactions between species that are the products of coevolution (such as parasite-host, predator-prey) and, thus, in terms of the “selected effect” account of function. The performance (...) of these functions under certain conditions maintain what Leopold took to be the healthy functioning of a land community. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Introduction:Beyond Nature/Culture Dualism: Let's Try Co-Evolution Instead of "Control"Ronnie Hawkins (bio)In the original call for papers for this special issue, nature/culture dualism was characterized as a way of thinking that holds human culture and nonhuman nature to be radically different ontological spheres, hyperseparated and oppositional, or, as Val Plumwood maintains in her essay, an orientation that assumes "separate casts of characters in separate dramas." In the human sphere, individuals (...) are unique and their lives are precious (at least theoretically), with concerns understood "from the inside," in terms of experience, intention and agency. In the sphere of nature, on the other hand, nonhuman beings are seen "from the outside," at best as replaceable members of species or populations needed for ecosystem functioning and, at worst, as unagentive, thinglike objects open for unbridled human exploitation. With our vast information and communication systems now largely in place, however, our human "noösphere" is rapidly enlarging to place us firmly within the biosphere (which, of course, in the imagery of Venn diagrams, must make up the larger circle on the screen), illuminating "both casts in both dramas," or perhaps joining all actors on the stage in a many-act, multidimensional play, the denoument of which, whether or not the extant lifeforms on this [End Page 1] planet will continue to evolve, remains as yet unwritten. The five essays in this collection speak to these points, and together they develop an alternative vision to our present dualistic impasse, seeing multiple natural agencies engaged with humanity in ongoing co-evolution and, as Freya Mathews suggests, raising the hope for a synergistic restructuring of lifeways that may yet save us from anthropogenic catastrophe.In "The Culture of Nature As Seen Through Mississippian Geographies," Jeff Baldwin shows us the broad scope of interacting agents, human and nonhuman, biological and geological, in what he terms "the nature-culture of the Mississippi River," as highlighted by the recent devastation of human habitation along the Gulf Coast of the United States wrought by Hurricanes Katrina and Rita. By enacting a role in which we "believe [our]selves to rule over a mechanistic world," we humans have, over the last century or so, stemmed the natural flooding of the Mississippi, rerouting the sediments that maintained and extended the delta, funneling them into the sea and thereby bringing about the subsidence and erosion of hundreds of square miles of coastal land. Concomitantly, we have let agricultural runoff from the huge Mississippi drainage basin eject excess nutrients into the Gulf of Mexico, stimulating algal blooms and die-offs, depleting the water of oxygen so as to create a hypoxic "dead zone" that is now the size of Massachusetts, and (though Baldwin does not discuss this aspect of the problem) we have released enough petrochemical pollution in the area to have earned the lower reaches of the River the name "Cancer Alley" decades ago. A failure to grasp the import of these large anthropogenic effects is, sadly, evident in calls for rebuilding the New Orleans area according to the same mechanistic model that has already proven so inadequate. Baldwin observes that the earth changes wrought through human cultural innovation often occur so rapidly, or have their negative feedbacks technologically so displaced through time and space, that their eventual impacts on the larger system may initially go unappreciated. His vision of "the culture of nature," however, is ultimately an optimistic one, since his functional understanding of culture is that it ultimately works toward mutualism, promoting increasingly appropriate relationships among all interacting components, and he finds evidence of a growing effort to establish an "intentional co-evolution," a conscious alignment of human projects with the ongoing projects of a living nature that encompasses them. [End Page 2]If Baldwin's essay helps us see our human activities "from the outside"—not just "from within" prevailing human culture, where they seem taken-for-granted necessities given a certain form of social construction, but as they alternatively appear inside biospherical space, often as inappropriate, exploitative interferences and intrusions—Stacey Sowards' essay, "Identification Through Orangutans: Destabilizing the Nature/Culture Dualism," explores the potential for our connecting with nonhuman life "from the inside," relating...

Aldo Leopold's land ethic has been extremely influential among people working in conservation biology, environmental ethics, and related fields. Others have abandoned the land ethic for purportedly being outdated or ethically untenable. Yet, both acceptance of the land ethic and rejection of the land ethic are often based on misunderstandings of Leopold's original meaning – misunderstandings that have become so entrenched as to have the status of myths. This essay seeks to identify and then debunk six (...) myths that have grown up around the land ethic. These myths include misunderstandings about how we should understand key terms like “stability” and “biotic community” as well as the scope and main message of the land ethic. Properly understanding Leopold's original meaning, a meaning derived from ideas he developed after a lifetime of scientific theorizing and hands-on practical knowledge, prevents hasty rejection and provides a sounder basis for conservation policy.

Ecocentrism, Hunting, the Biotic Pyramid, and Exotic Species Aldo Leopold's Land Ethic is famously holistic and ecocentric. The ecosystem, a holistic entity, has value over and above, and in most cases more than, the value of its individual components. This ecocentric perspective is summed up in the maxim: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise" (1970, 262).Ecocentrism explains Leopold's attitude toward hunting. In many passages, such as the October account of hunting ruffed grouse (58-62) and partridge (62-69), Leopold describes the hunt with approval. However, he disapproves of programs to eradicate keystone predators because their elimination impoverishes ecosystems. His classic account, "Thinking Like a Mountain," concerns wolf eradication. He writes, "I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise" (138). But he found that wolf eradication harms mountains, that is, ecosystems. I have watched the face of many a newly wolfless mountain, and seen the south-facing slopes wrinkle with a maze of new deer trails.

Abstract - Evolutionary, ecological and ethical studies are, at the same time, specific scientific disciplines and, from an historical point of view, structurally linked domains of research. In a context of environmental crisis, the need is increasingly emerging for a connecting epistemological framework able to express a common or convergent tendency of thought and practice aimed at building, among other things, an environmental policy management respectful of the planet’s biodiversity and its evolutionary potential. -/- Evolutionary biology, ecology and ethics: at (...) first glance, three different objects of research, three different worldviews and three different scientific communities. In reality, there are both structural and historical links between these disciplines. First, some topics are obviously common across the board. Second, the emerging need for environmental policy management has gradually but radically changed the relationship between these disciplines. Over the last decades in particular, there has emerged a need for an interconnecting meta-paradigm that integrates more strictly evolutionary studies, biodiversity studies and the ethical frameworks that are most appropriate for allowing a lasting co-evolution between natural and social systems. Today such a need is more than a mere luxury, it is an epistemological and practical necessity. -/- In short, the authors of this volume address some of the foundational themes that interconnect evolutionary studies, ecology and ethics. Here they have chosen to analyze a topic using one of these specific disciplines as a kind of epistemological platform with specific links to topics from one or both of the remaining disciplines. Michael Ruse’s chapter, for instance, elucidates some of the structural links between Darwinismand ethics. Ruse analyzes the Evolutionism vs. Creationism debate, emphasizing the risks run by scientists when they ideologize the scientific content of their studies. In the case of the contributions of Jean Gayon and Jean-Marc Drouin, which respectively deal with the disciplines of evolutionary biology and ecology, some central connections have been developed between these two disciplines, while reserving the option to consider in detail their topic in order to discover essential features ormeanings. Gayon analyzes the multilayered meanings of “chance” in evolutionary studies and the methodological implications that accompany such disparatemeanings. Froma similar analytical perspective, Drouin’s contribution focuses on the identification and critical evaluation of the different conceptions of time in ecology. Chance and time, factors of evolution in species and ecological systems, play a very important function in both disciplines, and these chapters help to capture their polysemous structure and development. Bryan Norton’s chapter, on adaptive environmental management, is set within an epistemological context where the Darwinian paradigm, ecological knowledge and ethical frameworks meet to give rise to practical, conservationist policies. In his contribution, Patrick Blandin pleads for the necessity of an eco-evolutionary ethics capable of fully encompassing humanity’s responsibility in the future determination of the biosphere’s evolutionary paths. Our value systems must recognize the predominant place that humanity has taken in the evolutionary history of the planet, and integrate the ethical ramifications of scientific advances in evolutionary and ecological studies. The chapter by J. Baird Callicott introduces us to a metaphorical ecological reversion with direct consequences for our moral conduct. If ecology showed that ecosystems are not organisms, recognizing organisms as a kind of ecosystem could be the basis for a new post-modern ecological ethics that lays the foundation for a better moral integration of humans with the environment. The contributions of Robin Attfield and Tom Regan delve into some of the classical issues in environmental ethics, situating them within a broader ecological and evolutionary context. Attfield’s chapter tackles the confrontation between individualistic and ecologically holistic perspectives, their different approaches to the issue of intrinsic value, and their tangled relation to monism and pluralism. Regan’s contribution ponders the criteria that allow individual beings, human and non-human, to own moral rights, the role of the struggle for existence in the relationship between species, and the logical difficulties involved in attributing intrinsic value to collective entities (species, ecosystems). Catherine Larrère’s chapter discusses the opposition between two environmental and ethical worldviews with very different philosophical centers of gravity: nature and technology. These opposing perspectives have direct consequences not only for the perception of the problems at hand and for what entities are deemed morally significant, but also for the proposed solutions. -/- To set out some foundational events in the history of evolutionary biology, ecology and environmental ethics is a first necessary step towards a clarification of their major epistemological orientations. On the basis of this inevitably nonexhaustive history, it will be possible to better position the work of the different contributors, and to build a meta-paradigm, i.e. a connecting epistemological framework resulting from one common or convergent tendency of thought and practice shared by different disciplines.

The sound system of a language must be able to support a perceptual contrast between different words in order to signal communicatively relevant meaning distinctions. In this paper, we use a simple agent-based exemplar model in which the evolution of sound-category systems is understood as a co-evolutionary process, where the range of variation within sound categories is constrained by functional pressure to keep different words perceptually distinct. We show that this model can reproduce several observed effects on the range (...) of sound variation. We argue that phonological systems can be seen as finding a relative optimum of variation: Efficient communication is sustained while at the same time, hidden category variation provides pathways for future evolution.

In lieu of an abstract, here is a brief excerpt of the content:The Future of Environmental PhilosophyJ. Baird Callicott (bio)The old guy in The Graduate had just one word for Dustin Hoffman's character, Ben: "plastics." This old guy has three words for the future pursuit of environmental philosophers, young and old: global climate change (GCC).GCC is emerging as the central environmental concern of the 21st century. Back in the 20th century, E. O. Wilson's mantra was (I paraphrase) 'abrupt mass anthropogenic (...) species extinction is the crime for which posterity is least likely to forgive us.' In view of the multifaceted catastrophe graphically depicted in the recent acclaimed film, An Inconvenient Truth (AIT), Wilson's dictum seems quaint. Rather, a world whose very geography will be anthropogenically altered by risen sea levels, whose weather will be increasingly violent and erratic, whose seas will be stagnant and acidified by carbonic acid, etc., etc., is the crime for which posterity is least likely to forgive us—if there is any posterity to make a judgment.According to Al Gore in AIT anthropogenic GCC is a "moral" and "ethical" issue. But he doesn't elaborate. And at the end of the film he provides a lame list of things you and you and you and you—all of us individually AND voluntarily—can do to mitigate GCC, such as swap out halogen light bulbs for compact florescent ones and drive a hybrid car. Think "tragedy of the commons" for the efficacy of that approach to an adequate ethical response to the challenge of GCC.Gore's naivete apart, environmental ethics (EE) as we know it is singularly ill-prepared for dealing with GCC. The problem is one of scale, temporal as well as spatial. Spatially, EE concern was focused on the scale of biotic communities, ecosystems, and landscapes. And the relevant science was ecology. Temporally, the scale was also ecological: It might take Prince William Sound half a century, perhaps even a whole century, to fully recover from the Exxon Valdez spill. In temperate climates, after a clearcut a mature forest might spring up in a century and, through ecological succession, if left alone it will return to old growth in 300 years. Back in the 20th century that seemed like a long time, and we lamented that the ecological temporal scale and the economic temporal scale of [End Page 119] industries like the timber business and the oil business were out of phase, the former measured in decades the latter in quarters. But now, elderly environmental philosophers like me will personally witness little more than the initial environmental consequences of GCC—the occasional Katrina, the occasional hottest year on record, the disappearance of glaciers in Glacier National Park. We won't live to see (I hope) the cessation of the Gulf Stream or sea-levels rise more than a few centimeters. And the rectification of these consequences will be completed, if they ever are, only after thousands of years have elapsed.How then do we scale EE up to meet the moral challenge of GCC? Spatially we have a huge leap to make from the landscape scale to the biospheric scale. We have to become conversant with a new set of sciences; the relevant sciences are not ecology and conservation biology, but biogeochemistry and earth-systems science.Is a GCC EE even possible? Maybe ethics has temporal-scale limits? We used to marvel at the long view of the Iroquois who considered the consequences of present policies out seven generations. Wow! At 25 years per generation that is all of 250 years (adding on the 75-year life-span of the 7th generation). Can we have ethical concern for the 37th generation, a thousand years out? Or the 121st generation 3000 years out?J. Baird Callicott J. Baird Callicott is Regents Professor of Philosophy and Religion Studies in the Institute of Applied Sciences at the University of North Texas. From 1997–2000 he served the International Society for Environmental Ethics as president.

The “land community” (or “biotic community”) that features centrally in Aldo Leopold’s Land Ethic has typically been equated with the concept of “ecosystem.” Moreover, some have challenged this central Leopoldean concept given the multitude of meanings of the term “ecosystem” and the changes the term has undergone since Leopold’s time (see, e.g., Shrader-Frechette 1996). Even one of Leopold’s primary defenders, J. Baird Callicott, asserts that there are difficulties in identifying the boundaries of ecosystems and suggests that we (...) recognize that their boundaries are determined by scientific questions ecologists pose (Callicott 2013). I argue that we need to rethink Leopold’s concept of land community in the following ways. First, we should recognize that Leopold’s views are not identical to those of his contemporaries (e.g., Clements, Elton), although they resemble those of some subsequent ecologists, including some of our contemporaries (e.g., O’Neill 2001, Post et al. 2007, Hastings and Gross 2012). Second, the land community concept does not map cleanly onto the concept of “ecosystem”; it also incorporates elements of the “community” concept in community ecology by emphasizing the interactions between organisms and not just the matter/energy flow of the ecosystem concept. Third, the boundary question can be illuminated by considering some of the recent literature on the nature of biological individuals (in particular, Odenbaugh 2007; Hamilton, Smith, and Haber 2009; Millstein 2009), focusing on concentrations of causal relations as determinative of the boundaries of the land community qua individual. There are challenges to be worked out, particularly when the interactions of community members do not map cleanly onto matter/energy flows, but I argue that these challenges can be resolved. The result is a defensible land community concept that is ontologically robust enough to be a locus of moral obligation while being consistent with contemporary ecological theory and practice.

Many philosophers have become familiar with Leopold’s land ethic through the writings of J. Baird Callicott, who claims that Leopold bases his land ethic on a ‘protosociobiological’ argument that Darwin gives in the Descent of Man. On this view, which has become the canonical interpretation, Leopold’s land ethic is based on extending our moral sentiments to ecosystems. I argue that the evidence weighs in favor of an alternative interpretation of Leopold; his reference to Darwin does not refer (...) to the Descent, but rather to the Origin of Species, where Darwin discusses the interdependencies between organisms in the struggle for existence.

Species evolve, very slowly, through selection of genes which give rise to phenotypes well adapted to their environments. The cultures, including the languages, of human communities evolve, much faster, maintaining at least a minimum level of adaptedness to the external, non- cultural environment. In the phylogenetic evolution of species, the transmission of information across generations is via copying of molecules, and innovation is by mutation and sexual recombination. In cultural evolution, the transmission of information across generations is by learning, and (...) innovation is by sporadic invention or borrowing from other cultures. This much is the foundational bedrock of evolutionary theory. But things get more complicated; there can be gene-culture co-evolution. Prior to the rise of culture, the physical environment is the only force shaping biological evolution from outside the organism, and cultures themselves are clearly constrained by the evolved biological characteristics of their members. But cultures become part of the external environment, and influence the course of biological evolution. For example, altruistic cultures with developed medical knowledge reduce the cost to the individual of carrying genes disposing to certain pathologies (such as diabetes); and such genes become more widespread in the populations maintaining such cultures. Assortative mating can affect biological evolution, and particular cultures may influence the factors which are sorted for in mating. (For a careful discussion of the effects of cultural evolution on natural selection, see Cavalli-Sforza and Bodmer, 1971:774- 804). This paper examines mechanisms involved in the co-evolution of a biological trait, the critical period for language acquisition, and a property of human cultures, the size of their languages. A gene/culture interaction will be shown that can be described as a kind of symbiosis, but perhaps more aptly as an `arms race'. In this introduction, we will sketch the basic mechanics of the interaction in very broad terms; the rest of the paper will explain and justify the details. The implications of our model for second language acquisition are given toward the end of the paper. (shrink)

A Great Plains land ethic is shaped by an intimate knowledge of and appreciation for the evolution, ecology, and aesthetics of the plains landscape. The landscape evokes a sense of wonder and mystery suggested by the word "sacrament."

In contrast to an anthropocentric ethic which emphasizes human dominion over nature, a Theo-centric (...) class='Hi'>land ethic seeks a balance, reflected in Genesis 1–3, between humans who are members of the earth community and moral agents accountable to God for the earth. A land ethic identifies concrete practices of metanoia and healing: agricultural practices to address the loss and degradation of soil; conservation and protection of water sources; utilization of wind and solar energy; and prescribed burning to restore processes vital to the prairie ecosystem. The concept of subsidiarity suggests that practices of metanoia and healing are a combination of wise public policy balanced by personal, family, church, business, and community responsibility.

The term “legacy effect” has been used in ecology since the early 1990s by authors studying plant succession, invasive-plant impacts, herbivory impacts, ecosystem engineering, and human land-use impacts. Although there is some variability in usage, the term is normally used to describe impacts of a species on abiotic or biotic features of ecosystems that persist for a long time after the species has been extirpated or ceased activity and which have an effect on other species. For example, human (...) agricultural activities may have a legacy effect on soil structure and vegetative communities that lasts for centuries and which alters current communities. The concept may be related to the idea of ecological inheritance in evolutionary biology but would refer only to a subset of the features of this concept. In particular, legacy effects could refer to those kinds of ecological inheritance where a physical or biological change in ecosystem state is caused by one species, where this change persists after the extirpation of the causal species and alters selection pressure of another species much later in time.

In biosemiotics, living beings are not conceived of as the passive result of anonymous selection pressures acted upon through the course of evolution. Rather, organisms are considered active participants that influence, shape and re-shape other organisms, the surrounding environment, and eventually also their own constitutional and functional integrity. The traditional Darwinian division between natural and sexual selection seems insufficient to encompass the richness of these processes, particularly in light of recent knowledge on communicational processes in the realm of life. Here, (...) we introduce the concepts of semiotic selection and semiotic co-option which in part represent a reinterpretation of classical biological terms and, at the same time, keep explanations sensitive to semiosic processes taking place in living nature. We introduce the term ‘semiotic selection’ to emphasize the fact that actions of different semiotic subjects (selectors) will produce qualitatively different selection pressures. Thereafter, ‘semiotic co-option’ explains how semiotic selection may shape appearance in animals through remodelling existing forms and relations. Considering the event of co-option followed by the process of semiotic selection enables us to describe the evolution of semantic organs. (shrink)

This volume handles in various perspectives the concept of function and the nature of functional explanations, topics much discussed since two major and conflicting accounts have been raised by Larry Wright and Robert Cummins’s papers in the 1970s. Here, both Wright’s ”etiological theory of functions’ and Cummins’s ”systemic’ conception of functions are refined and elaborated in the light of current scientific practice, with papers showing how the ”etiological’ theory faces several objections and may in reply be revisited, while its counterpart (...) became ever more sophisticated, as researchers discovered fresh applications for it. Relying on a firm knowledge of the original positions and debates, this volume presents cutting-edge research evincing the complexities that today pertain in function theory in various sciences. Alongside original papers from authors central to the controversy, work by emerging researchers taking novel perspectives will add to the potential avenues to be followed in the future. Not only does the book adopt no a priori assumptions about the scope of functional explanations, it also incorporates material from several very different scientific domains, e.g. neurosciences, ecology, or technology. In general, functions are implemented in mechanisms; and functional explanations in biology have often an essential relation with natural selection. These two basic claims set the stage for this book’s coverage of investigations concerning both ”functional’ explanations, and the ”metaphysics’ of functions. It casts new light on these claims, by testing them through their confrontation with scientific developments in biology, psychology, and recent developments concerning the metaphysics of realization. Rather than debating a single theory of functions, this book presents the richness of philosophical issues raised by functional discourse throughout the various sciences.​ Content Level » Research Keywords » Causal role theory of functions - Determination of content - Ecosystem selection - Etiological theory of function - Evolutionary biology - Functional explanations - Historical concepts in biology - Larry Wright - Neurosciences - New mechanism - Selected effects functions - Systemic theory of functions - William Wimsatt Related subjects » Anthropology & Archaeology - Epistemology & Philosophy of Science - Evolutionary & Developmental Biology - Neuroscience - Philosophy TABLE OF CONTENTS Introduction.- Section I.

Modern ethical perspectives toward the environment often emphasize the connection of humans to a broader biotic community. The full intimacy of this connectedness, however, is only now being revealed as scientific findings in developmental biology and genetics provide new insights into the importance of environmental interaction for the development of organisms. These insights are reshaping our understanding of how organism-environment interaction contributes to both consistency and variation in organism development, and leading to a new perspective whereby an “organism” is (...) not solely viewed as the adaptive product of evolutionary selection to an external environment over generations, but as continuously being constructed through systems of interactions that link an organism’s characteristics developmentally to the physical and social influences it experiences during life. This newfound emphasis on “interaction” leads to an interdependency whereby any change to an “environment” impacts the interacting “organism,” and an alteration to the “organism” eventually affects its “environment.” The causal reciprocity embedded within this organism-environment interdependency holds implications for our moral obligations to environments, given their compulsory role in shaping all organisms including ourselves.

Foot , Hursthouse , and Thompson , along with other philosophers, have argued for a metaethical position, the natural goodness approach, that claims moral judgments are, or are on a par with, teleological claims made in the biological sciences. Specifically, an organism’s flourishing is characterized by how well they function as specified by the species to which they belong. In this essay, I first sketch the Neo-Aristotelian natural goodness approach. Second, I argue that critics who claim that this sort of (...) approach is inconsistent with evolutionary biology due to its species essentialism are incorrect. Third, I contend that combining the natural goodness account of natural-historical judgments with our best account of natural normativity, the selected effects theory of function, leads to implausible moral judgments. This is so if selected effects function are understood in terms of evolution by natural selection, but also if they are characterized in terms of cultural evolution. Thus, I conclude that proponents of the natural goodness approach must either embrace non-naturalistic vitalism or troubling moral revisionism. (shrink)

While it seems unlikely that any method of guaranteeing human-friendliness on the part of advanced Artificial General Intelligence systems will be possible, this doesn’t mean the only alternatives are throttling AGI development to safeguard humanity, or plunging recklessly into the complete unknown. Without denying the presence of a certain irreducible uncertainty in such matters, it is still sensible to explore ways of biasing the odds in a favorable way, such that newly created AI systems are significantly more likely than not (...) to be Friendly. Several potential methods of effecting such biasing are explored here, with a particular but non-exclusive focus on those that are relevant to open-source AGI projects, and with illustrative examples drawn from the OpenCog open-source AGI project. Issues regarding the relative safety of open versus closed approaches to AGI are discussed and then nine techniques for biasing AGIs in favor of Friendliness are presented: 1. Engineer the capability to acquire integrated ethical knowledge.2. Provide rich ethical interaction and instruction, respecting developmental stages.3. Develop stable, hierarchical goal systems.4. Ensure that the early stages of recursive self-improvement occur relatively slowly and with rich human involvement.5. Tightly link AGI with the Global Brain.6. Foster deep, consensus-building interactions between divergent viewpoints.7. Create a mutually supportive community of AGIs.8. Encourage measured co-advancement of AGI software and AGI ethics theory.9. Develop advanced AGI sooner not later. In conclusion, and related to the final point, we advise the serious co-evolution of functional AGI systems and AGI-related ethical theory as soon as possible, before we have so much technical infrastructure that parties relatively unconcerned with ethics are able to rush ahead with brute force approaches to AGI development.

Explanatory Externalism states that the only adaptive force in evolution is natural selection. Explanatory Externalism is a central thesis of the Modern Evolutionary Synthesis. The etiological theory of natural selected-effect functions also advocates Explanatory Externalism. According to this theory, natural selection is the process responsible for determining the proper natural functions of traits. However, I will point out several challenges to Explanatory Externalism that are proposed primarily by developmental biology and its various subfields. Based on these challenges, this paper (...) will argue why biological functions cannot be fully explained by the selected-effect theory, i.e., that a theory of biological functions must adopt some kind of Explanatory Internalism. At the end of this paper, I will discuss whether or not Explanatory Internalism entails a pluralistic view of biological functions, and how this discussion is related to the different explanations of fit and diversity found in evolutionary biology.

The selected effects or ‘etiological’ theory of Proper function is a naturalistic and realist account of biological teleology. It is used to analyse normativity in philosophy of language, philosophy of mind, philosophy of medicine and elsewhere. The theory has been developed with a simple and intuitive view of natural selection. Traits are selected because of their positive effects on the fitness of the organisms that have them. These ‘selected effects’ are the Proper functions of (...) the traits. Proponents argue that this analysis of biological teleology has the unique advantage that the selected effect function of a trait is also a causal explanation of the trait: the trait exists because it performs this function. We show, however, that selected effect functions as currently defined explain the existence of traits only under highly restrictive assumptions about evolutionary dynamics. In many common scenarios in which traits evolve by natural selection, selected effect functions do not explain those traits. This is because definitions of selected effect function extract from any evolutionary scenario only the information that would be explanatorily relevant in the simple evolutionary scenario implicit in those definitions. When applied to more complex scenarios selected effect functions omit the key information that is explanatorily relevant in those scenarios. The assumptions required for selected effect functions to be explanatory are particularly unlikely to hold in the domain that its proponents care most about - the evolution of representation. A more adequate selected effects theory of Proper functions may be possible, but will require much greater attention to the structure of actual evolutionary explanations. (shrink)

Philippa Foot and Rosalind Hursthouse, along with other philosophers, have argued for a metaethical position, the natural goodness approach, that claims moral evaluations are, or are on a par with, teleological claims made in the biological sciences. Specifically, an organism’s flourishing is characterized by how well they function as specified by the species to which they belong. In this essay, I first sketch the Neo-Aristotelian natural goodness approach. Second, I argue that critics who claim that this sort of approach is (...) inconsistent with evolutionary biology due to its species essentialism are in- correct. Third, I consider the prospects of understanding ethical normativity as a species of biological teleology claiming that this would be incompatible with our considered moral judgments. Fourth, after presenting gene-culture coevolution theory, I argue that the only way of reconciling naturalism and normativity in accordance with the natural goodness approach requires amending the selected effects function account to include cultural evolution. However, this approach, though not biologically reductionistic, still generates claims incompatible with our considered moral judgments. Finally, I end with a discussion of methodology and revisionistic moral theories. (shrink)

This book explores issues at the core of modern linguistics and cognitive science. Why are all languages similar in some ways and in others utterly different? Why do languages change and change variably? How did the human capacity for language evolve, and how far did it do so as an innate ability? Simon Kirby looks at these questions from a broad perspective, arguing that they can be studied together. The author begins by examining how far the universal properties of language (...) may be explained by examining the way it is used, and how far by the way it is structured. He then considers what insights may be gained by combining functional and formal approaches. In doing so he develops a way of treating language as an adaptive system, in which its communicative and formal roles are both crucial and complementary. In order to test the effectiveness of competing theories and explanations, Simon Kirby develops computational models to show what universals emerge given a particular theory of language use or acquisition. He presents here both the methodology and the results. Function, Selection, and Innateness is important for its argument, its methodology, and its conclusions. It is a powerful demonstration of the value of looking at language as an adaptive system and goes to the heart of current debates on the evolution and nature of language. (shrink)

This paper focuses on natural aesthetics as it relates to an ecological ethics informed by Aldo Leopold and by two contemporary environmental ethicists inspired by him: Callicott and Rolston. By contrast to Callicott, Rolston's work emphasises the distinctive character of natural beauty and gives reasons to understand such beauty as foundational for acting morally in the natural world. This paper argues, on these theoretical grounds, that an informed natural aesthetics is a requirement of an environmental ethics on account of the (...) co-relational link between the integrity, balance and beauty of the biotic community. This more objective foundation can better support conservationist movements in practice, bringing together natural beauty and duty in the pursuit of a closer harmony between humankind and the natural world.

This paper is about the actual and potential development of an ethics that is appropriate to the practices and institutions of biobanking, the question being how best to develop a framework within which the relevant ethical questions are first identified and then addressed in the right ways. It begins with ways in which a standard approach in bioethics – namely upholding a principle of individual autonomy via the practice of gaining donors’ informed consent – is an inadequate ethical framework for (...) biobanking. In donating material to a biobank, the individual donor relinquishes a degree of control and knowledge over the way their material is used in large-scale and typically open ended projects; and the identifying nature of genetic material means that third parties have rights and interests which must be taken into account as well as those of the individual donor. After discussing the problems for informed consent in the biobanking context, the paper then considers three emerging alternative approaches which, broadly speaking, conceptualize the subject of biobanking ethics in communal or co-operative terms: one version sees participants in biobanking research as ‘shareholders’ whilst the other expands on the notion of participation to include the wider public beneficiaries of biobanking as ‘stakeholders’. It concludes by outlining a third view, on which the biobanking institution itself is conceived as an ethical subject whose defining function can do useful normative work in guiding and evaluating its activities.

Many accounts of ethnic phenomena imply that processes such as stereotyping, essentialism, ethnocentrism, and intergroup hostility stem from a unitary adaptation for reasoning about groups. This is partly justified by the phenomena’s co-occurrence in correlational studies. Here we argue that these behaviors are better modeled as functionally independent adaptations that arose in response to different selection pressures throughout human evolution. As such, different mechanisms may be triggered by different group boundaries within a single society. We illustrate this functionalist framework using (...) ethnographic work from the Quechua-Aymara language boundary in the Peruvian Altiplano. We show that different group boundaries motivate different ethnic phenomena. For example, people have strong stereotypes about socioeconomic categories, which are not cooperative units, whereas they hold fewer stereotypes about communities, which are the primary focus of cooperative activity. We also show that, despite the cross-cultural importance of ethnolinguistic boundaries, the Quechua-Aymara linguistic distinction does not strongly motivate any of these intergroup processes.

Social media has become an important way for science communication. Some scholars have examined how to help scientists engage with social media from operational training, policy guidance, and social media services improving. The main contribution of this study is to construct a symbiosis evolution model of science communication ecosystem between scientists and social media platforms based on the symbiosis theory and the Lotka–Volterra model to discuss the evolution of their symbiotic patterns and population size under different symbiosis coefficients. The results (...) indicate that the size of the symbiosis coefficients determines the equilibrium outcome of the symbiosis evolution of scientists and social media platforms; scientists and social media platforms can promote each other’s population size under the mutualism pattern, which can achieve sustainable science communication; “1 + 1 > 2” effect can only be achieved under the symmetric mutualism pattern and the growth of scientists and social media platforms is more stable and sufficient than that of other patterns. The findings will provide additional perspectives for promoting the sustainable development of science communication based on social media. (shrink)

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.

True Darwinian Ethics -/- Darwin’s model for the evolution of morality as presented in Descent of Man (1871) is shown to comprise three major stages that are here referred to as empathic premorality, tribal morality, and universalizing morality. Empathy, the key component of Darwin’s “social instincts” that started moral evolution, is here recognized as the principal cognitive device that conveys epistemic credibility to moral agency. The two constitutive elements of the tribal morality are conscience that Darwin conceived of as a (...) conflict between a lasting social motive and an immediate selfish impulse, and true altruism that evolved as a result of group (community) selection. Darwin’s genius recognized the uniqueness of group selection in human evolution as being dependent on mental faculties and speech that facilitated habit formation through praise and blame form other group members, with empathy as a gauge of others’ emotional reactions. Contrary to repeated claims, Darwin did not derive morality from reciprocity that he (and his contemporaries) considered to be “a low motive”, and adduced it only as a mechanism of habit formation. The universalizing morality was brought about by the increasing powers of intellect that led to respecting individual lives (rather than group interests only) and extending humane concerns beyond one’s group, ultimately to all sentient beings, which places Darwin among the spiritual fathers of modern humanitarianism. In terms of substantive ethics, Darwin’s views support moral individualism that requires to treat each subject according to his/her individual characteristics rather than any group membership. Darwin’s moral individualism and universalism have been elaborated by Peter Singer as the principle of equal consideration of interests and the expanding circle of ethics, respectively. Darwin’s model of moral evolution, which starts with intuitive but epistemically reliable moral agency and then allows for its rational improvement, provides a way out of the moral subjectivism of evolutionary ethics that reduces morality to an adaptation to social life. The primary or core morality that relies on empathy and implements reciprocity supports welfare (wellbeing) of a group and its members. Welfare (which has been defined by Darwin) is a basic “terminal” (ultimate) value that constitutes an objective, measurable fact. Since the primary morality supports welfare, it is objectively good, which justifies an ethical reasoning that such morality ought to be extended (with appropriate adjustments) to all sentient beings. Confusion over the status of morality is largely due to the lack of appreciation of its complexity: not only had its motivational apparatus (known as the moral agency) evolved by superposition of many emotional and pure cognitive mechanisms, but it has subsequently been co-opted to implement prudential, religious and possibly other norms that are accidental and sometimes contrary to its original social function. Those secondary morality norms are now enforced by the moral agency but lack moral objectivity and thus may support the perception of moral subjectivism and relativism. In short, true Darwinian ethics is based on the scientific axiology that recognizes evolutionary origins of all values, requires respecting all values that are experienced by each and every subject according to its individual characteristics, and calls for a critical assessment of each and every received morality.

Synthetic biology promises to eliminate the distinction between biology and engineering by delivering a philosophically interesting new kind of entity: a biological organism that is wholly designed and constructed by humans. The possibility of such organisms raises interesting questions in three domains: the analysis of (1) biological functions, (2) engineering functions, and (3) health and disease. This paper identifies and systematically answers these questions. This does not only establish how we should think about functions and health and disease in synthetic (...) biological organisms, but it also reveals insights that are of broader relevance: (1) aetiological accounts of biological function need to omit or reinterpret reference to natural selection. This results in complete continuity between aetiological analyses of function in engineering and philosophy; (2) considering synthetic biology prompts interesting further questions about heritability, ancestry, and biological individuals; and (3) accounts of disease as biological dysfunction do not straightforwardly map onto our intuitive health and disease judgments regarding non‐human animals. In response to the latter point I examine three possible avenues, and tentatively defend one on behalf of the ‘disease as dysfunction’ theorist. (shrink)

Holistic accounts of the natural environment in environmental ethics fail to stress the distinction between the concepts of comnlunity and organism. Aldo Leopold’s “Land Ethic” adds to this confusion, for it can be interpreted as promoting either a community or an organic model of nature. The difference between the two concepts lies in the degree of autonomy possessed by constituent entities within the holistic system. Members within a community are autonomous, while the parts of an organism are not. Different (...) moral conclusions and environmental policies may result from this theoretical distinction. Treating natural entities as parts of an organism downgrades their intrinsic value as individual natural beings, since the only relevant moral criterion in an organic environmental ethic is the instrumental value that each natural entity has for the system. This ethic allows instances of the “substitution problem”-the replacement of one entity in an ecosystem by another provided that the overall functioning of the system is notharmed. However, since substitution violates environmentalist principles, for example, calling for respect for the integrity of the entities in a natural system, an organic environmental ethic must be rejected. A community model focuses on both the functional value and the autonomous intrinsie value of natural entities in a system. A community environmental ethic thus avoids the substitution problem.

In the United States, the chasm-like inequities laid bare by COVID-19, the ongoing killing of black Americans, the violent insurrection at the Capitol, and the continuing attempt to subvert the electoral process are powerful indicators of a system under severe strain (Guardian Staff; Rubin). These developments are also a sign of deep and chronic problems, including the following:1. Increasing economic, political, social, educational, and health inequalities2. Increasing racism, anti-Semitism, and xenophobia3. Increasing attacks on science, knowledge, and democracy itself4. Declining trust in nearly all major institutionsMany things, obviously, contribute to the present situation. Among them is the failure of universities to successfully do what they are supposed to do: educate students to be ethical, empathetic, engaged, democratic citizens, and [End Page 49] advance knowledge for the continuous betterment of the human condition (Benson et al., Knowledge). To use a Marxian framework, but to reject its economic determinism, universities, in my judgment, are not a part of society’s superstructure. They are, to the contrary, a core component of its base (Marx, “Preface”). What they do matters enormously, significantly determining the kind of society we have now and will have in the future.Universities, as former Harvard president Derek Bok and others have emphasized, have become the central societal institutions in the world (Bok, Universities and the Future 3). Research universities, in my judgment, are the most central. They develop new ideas and technologies, incubate businesses, serve as cultural and artistic centers, and are engines of local, national, and global economies. As anchor institutions, they often engage in partnerships with government, the private sector, and community-based organizations to revitalize local neighborhoods and schools (“Anchor Institutions Task Force”). It is the university’s role as an educational institution, however, that is most important.The schooling system increasingly functions as the core subsystem—the strategic subsystem—of modern information societies. Schooling, more than any other subsystem, as John Dewey claimed, influences the functioning of the societal system as a whole. Viewed systemically, it has on balance the greatest “multiplier” effects, direct and indirect, short-term and long-term. Restating these points somewhat differently, I strongly agree with the Chilean sociologist Eugenio Tironi that the answer to the question “What kind of education do we need?” is to be found in the answer to the question “What kind of society do we want?” (Tironi). Education and society are dynamically interactive and interdependent. If human beings hope to maintain and develop a particular type of society, they must develop and maintain the particular type of education system conducive to it. As Dewey in effect argued: No effective democratic schooling system, no democratic society.1For William Rainey Harper, who, as the first president of the University of Chicago, brought Dewey to Chicago, universities are the primary shapers of the American schooling system. In an 1899 speech at the University of California, he perceptively observed that “[t]he school system, the character of which, in spite of itself, the university determines and in a large measure controls.... [T]hrough the school system every family in this entire broad land of ours is brought into touch with the university; for from it proceed the teachers or the teachers’ teachers” (Harper 25). Agreeing with Harper, I contend that higher education institutions powerfully shape the learning, values, and aspirations of students from kindergarten through graduate school. [End Page 50]Given the university’s societal role and influence, creating and sustaining an inclusive, just democratic society requires a... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.1 (2002) 124-137 [Access article in PDF] Katz's Problematic Dualism and Its "Seismic" Effects on His Theory Wayne Ouderkirk There is much to admire in Eric Katz's Nature as Subject. 1 Many aspects of his theory strongly resonate with dominant themes in environmental ethics and with my own theoretical predilections. In addition, he applies his theory to several major environmental issues (ecological restoration and (...) the Amazon rainforest, to name two), simultaneously testing it against other views and tracing out its implications. Impressive, non-ivory tower philosophizing. The array of issues he covers is impressive too, from the place of animal rights in an environmental ethic to the relation between environmental destruction and genocide; from the tension between holism and the rights of individuals to intrinsic value; from anthropo- centrism to Judaism and the environment; from the history of environmental thought to the convergence hypothesis. And more.In light of this tremendous range and of my own attraction to such of his major themes as ecocentrism, it might seem unappreciative to criticize, [End Page 124] to dissent. But despite all the positives I find in Katz's writings, I also find faults there, faults which, when pressed, cause major fissures in the whole. The central, major problem is Katz's dualism; and I think it ultimately undoes his whole theory, since it is so intimately connected with the other parts. Within Katz's own essays, there are, I think, resources to begin a reconstruction; but as with any other such effort, the first task is to discard the parts that are no longer useable. Before doing so, however, I want to review some positive aspects of Katz's theory, lest I convey the mistaken impression that my initial praise for his work is mere courtesy. The Solid Geological Features To begin with the most general: Katz's concern for, commitment to the natural world is obvious to any reader. He suffuses every essay with a determination to seek out clear and cogent philosophical rationales for its protection. More important perhaps is his obvious personal connection to that world. His references to Fire Island's deer and beaches, for example, amply demonstrate what the rest of his writings imply: that his theoretical efforts are more than armchair musings about a current philosophical issue. Katz's efforts are both professional and passionate.On a more specifically philosophical level, I regard his anti-anthropocentrism as a significant strength. Though one can, of course, be an anthropocentrist and be an environmental philosopher—Bryan Norton (1984) and Eugene Hargrove (1989) come to mind—I think Katz's arguments showing that anthropocentric views can only offer contingent justifications for protecting the environment are cogent and valid (3-11). An important part of those arguments is Katz's demonstration that different theories in environmental philosophy do indeed result in different environmental policies. In other words, Katz offers a strong counterargument to Norton's convergence hypothesis (Norton 1991), the idea that, given environmentalists' shared commitment to the environment, the various philosophical theories offered in justification of that commitment will converge on similar policy recommendations (149 ff.). I agree with Katz's refutation of that hypothesis, and I offer my critique of his theory because I think that theory's faults will ultimately undermine sound policies.Another big asset of Katz's theory is his communitarianism, the idea that we are part of an ecological community, an ecosystem, to which we have moral obligations. Not surprisingly to anyone familiar with environmental ethics, the source of this idea is Aldo Leopold's Land Ethic (Leopold 1966), [End Page 125] which has been debated, analyzed, praised, and critiqued more than extensively in the literature. Katz pretends to no originality here; he simply adopts and vigorously defends an ecocentric ethic that counts the integrity, stability, and beauty of the system—including, not incidentally, abiotic components—as central criteria limiting human interference with nature. Unlike, for example, the total ecocentrism of J. Baird Callicott's (1980) early writing, however, Katz tempers his communitarianism with another dimension, qualifying his holistic... (shrink)

As proposed for the emergence of modern languages, we argue that modern uses of languages (pragmatics) also evolved gradually in our species under the effects of human self‐domestication, with three key aspects involved in a complex feedback loop: (a) a reduction in reactive aggression, (b) the sophistication of language structure (with emerging grammars initially facilitating the transition from physical aggression to verbal aggression); and (c) the potentiation of pragmatic principles governing conversation, including, but not limited to, turn‐taking and inferential (...) abilities. Our core hypothesis is that the reduction in reactive aggression, one of the key factors in self‐domestication processes, enabled us to fully exploit our cognitive and interactional potential as applied to linguistic exchanges, and ultimately to evolve a specific form of communication governed by persuasive reciprocity—a trait of human conversation characterized by both competition and cooperation. In turn, both early crude forms of language, well suited for verbal aggression/insult, and later more sophisticated forms of language, well suited for persuasive reciprocity, significantly contributed to the resolution and reduction of (physical) aggression, thus having a return effect on the self‐domestication processes. Supporting evidence for our proposal, as well as grounds for further testing, comes mainly from the consideration of cognitive disorders, which typically simultaneously present abnormal features of self‐domestication (including aggressive behavior) and problems with pragmatics and social functioning. While various approaches to language evolution typically reduce it to a single factor, our approach considers language evolution as a multifactorial process, with each player acting upon the other, engaging in an intense mutually reinforcing feedback loop. Moreover, we see language evolution as a gradual process, continuous with the pre‐linguistic cognitive abilities, which were engaged in a positive feedback loop with linguistic innovations, and where gene‐culture co‐evolution and cultural niche construction were the main driving forces.

“Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms. (...) This essay critically explores various interpretations of this analogy. It suggests that these interpretations can be explicated by contrasting adaptationist with pluralist readings of the evolutionary concept of adaptation. Among the possible interpretations of the relations between biological adaptations and their analogues in language and culture, the two most relevant are a linear, hierarchical, signalling-based model that takes its cues from the evolution of co-operation and joint intentionality and a mutualistic, pluralist model that takes its cues from mimesis and symbolism in the evolution of human communication. Arguing for the merits of the mutualistic model, the present analysis indicates a path towards an evolutionary pluralist version of biosemantics that will align with theories of cognition as being environmentally “scaffolded”. Language and other cultural forms are partly independent reproducible structures that acquire proper functions of their own while being integrated with organism-based cognitive traits in co-evolutionary fashion.

The main subject of this paper is the two significant problems of environmental ethics which are ecofascism and speciesism. This scrutiny offers an evaluative perspective on the main problems of environmental ethics and is conducted with this aim. Most of the environmental philosophers, all the difficulties notwithstanding, try to find a middle way in the ecofascism-speciesism continuum and their theories get closer to one or the other edge of this continuum. John Baird Callicott is one of the environmental philosophers who (...) struggle with this issue when his theory indicates one of the problems or gets closer to one of the edges, he tries to find a new way to go. There are six turns in Callicott's philosophy starting with strong holism due to accepting Leopold's land ethic as a basis. Then, he constructed a theory that pushes him closer to the speciesist edge, and finally, he found a way out from these fatal consequences. However, all the environmental philosophers face the same problems in their journey although they are either holists or individualists in the end. In constructing a holistic environmental ethical theory, for instance, they may be in ecofascism difficulty because holism requires man to be an ordinary member of the biotic community as seen in the first turn. Or, establishing a special place for humankind to ditch the ecofascism crisis may cause another equally important crisis, namely, speciesism (see the third turn). Some philosophers prefer to be closer to one of the edges always being on guard against the other. Some others, like Callicott, try to find a middle way equally far from the edges. However, this choice is no easier. Selecting to be a member of both the human community and biotic community brings different problems, such as ranking problems between the duties and obligations toward the communities and their members, i.e. a challenge to decision-making processes. For such problems, they come up with some principles or rules like second-order principles (SOPs) as Callicott did (in the fifth turn). But, these rules or principles are not sufficient enough to solve the ranking problems of setting priorities among our duties to members of both communities, either. Thus, either there is a need for more regulations and rules, or these two communities should be separated in a different dimension and gathered at another level. The second choice is preferred by Callicott and used as a solution to the main problem: constructing an environmental ethical theory that involves whole nature with its members and which is free from two essential problems (see the sixth turn). As a final point, Callicott's last theory seems to point to the conclusion that an environmental ethical theory is possible without falling into the ecofascism and speciesism traps, i.e. his last stand can facilitate the attainment of the main subject of this essay.

Aldo Leopold’s “Land Ethic” centers on the maxim: “A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.” I contribute to the critical appraisal of this maxim by providing answers to the following questions: (1) what is referred to by the phrase “the integrity, stability, and beauty of the biotic community”? (2) What “things” tend to preserve or threaten the integrity, stability, and (...) beauty ofthe biotic community? (3) Are the integrity, stability, and beauty ofthe biotic community goods such that preserving them is right and failing to do so wrong? (shrink)

Introduction. A human and the world are an organically connected part and whole, they are always a single World, and therefore they can only evolve together, in one direction. The human world consists of many interconnected and interdepend- ent parts. If any one of the parts (for example, technology) begins to dominate and claim the sta- tus of the whole, then the problem of violating the optimal ratio in the coexistence and co-evolutionary development of each of the parts, and hence (...) the whole itself, becomes aggravated. Hence, the eco-humanistic problem arises. The purpose of the work is to present the content and substantiate the theoretical and practical significance of eco-humanism as a new humanitar- ian knowledge and methodology for understanding the specifics of the relationship “man — technical and-technological world”. Methods. The author uses the methods of dia- lectics, systemic and synergetic approaches, the project (projective) method, which is implemented in the design and development of a new philo- sophical and scientific discipline of eco-humanism, and ideas of co-evolution. Scientific novelty of the research. The author determines basic foundations of eco-humanism as a new type of humanitarian knowledge; formulates and meaningfully substan- tiates the main principles of eco-humanism as a methodological setting for the ecologization of a person and the world: optimality, coordination and dominance of the whole (integrity) in relation to its parts. Results. Eco-humanistics is defined as a new type of knowledge about a person and a specific setting of his thinking and practical activities, focused on finding ways and means to achieve op- timality in relation to various aspects (for example, technical and anthropological) in a person’s being to ensure the possibility of their fruitful existence, to preserve and reproduce a person (as a unique integrity) and his world (as a universal integrity), in their interconnected and interdependent unity. Conclusions. The author of the article comes to the conclusion that the theoretical development of eco-humanistics will make it possible to study and analyze the phenomena of modern culture in a more multifaceted way, to get a more accurate interpretation of the ways of human existence and eco-cultural practices that provide the effect of the state of the “ecosystem” in situations of any intense socio-cultural transformations.

In lieu of an abstract, here is a brief excerpt of the content:Future Environmental Philosophies and Their Biocultural Conservation InterfacesRicardo Rozzi (bio)Perhaps it would be better to speak of the future of environmental philosophies, rather than of the future of environmental philosophy. Making explicit a plurality of future trends helps prevent an "Anglo-academic" bias, and emphasizes the need for further developing environmental philosophy into at least two directions: (1) a stronger dialogical interaction with the diverse international constellation of cultural, ethnic, (...) social, political, economic, and ecological dimensions of environmental problems; and (2) a greater integration into the transdisciplinary field of biological and cultural conservation, involving an enhanced actualization of environmental theoretical philosophy into environmental practical philosophy.1. Toward more multi-discursive international environmental philosophiesFurther developing international environmental philosophy can help [End Page 142] to more precisely identify agents and causes of environmental problems, as well as their effects and victims. For instance, the focus on global climate change—and more generally global change, including other processes of rapid environmental transformation such as biotic, linguistic, and cultural homogenization—should not overlook the fact that different human communities, regions, societies, and countries are not equally responsible for such change nor suffer equally from its consequences. For example, today the highest levels of UV radiation fall on areas of Patagonia and the Antarctic Peninsula. These regions are the farthest away from the centers of CFC emissions which generate the stratospheric ozone hole found over the austral portion of the Americas.1 The incorporation of these type of regional distinctions into environmental philosophy provides the opportunity for more precise diagnoses and characterizations of environmental problems than the still-frequent generalizations stated in terms of problems between "humanity and nature."2 Such a lack of specificity is deceptive because it absolves particular responsible agents of environmental problems by referring to all humans or society in general as responsible for them.Secondly, contrasting ecological, social, and political settings generate not only different environmental problems, but also offer a variety of viable options for solving those problems. This is a point that remains frequently overlooked within global environmental agendas. While working in conservation in Latin America, I am continuously surprised by the marked ecological and cultural singularities I find in different localities in which communities have evolved peculiar ways of understanding, valuing, and interacting with their environments.3 On the one hand, environmental philosophy would enrich itself by further incorporating this biocultural diversity. On the other hand, environmental philosophy could provide a valuable contribution to biocultural conservation by better articulating the understanding the reticulate diversity of ecological knowledge and practices that indigenous and non-indigenous old-resident communities have co-evolved with particular ecosystems and historic and cultural settings around the world.Finally, furthering the participation of environmental thinkers of different regions and strengthening environmental philosophy networks could contribute to an international dialogue that would generate more pertinent concepts and propositions by more deeply embracing local [End Page 143] social, historical, political, cultural, linguistic, and ecosystem realities. The dynamic diversity of human ecological worldviews and practices has been addressed by the field of environmental philosophy;4 however, this diversity has still not been sufficiently incorporated as part of a multi-discursive community.* * *2. Incorporating environmental philosophy into the theory and praxis of biocultural conservationDuring the last two decades, a main goal of ecological sciences and biological conservation has been a better integration between human and natural systems. Under currently prevailing scientific approaches, such reconnection has been developed primarily through economic valuation of "ecosystem services" (see, for example, the recent landmark Millennium Ecosystem Assessment).5 Environmental philosophy has had a weak presence as compared to ecological economics in the transdiscipline of biological conservation. This weak presence is mismatched with the numerous calls made by ecologists about the need for environmental ethics, and with the frequent reference to ethical values made by international environmental conventions. For instance, the text of the Convention on Biological Diversity begins with a reference to the intrinsic value of biodiversity but it does not develop this notion at all.6 Similarly, the Millennium Ecosystem Assessment mentions the intrinsic value of biodiversity but does not develop the notion, and ends up justifying the need for its conservation in terms of economic values...

This article offers an analysis of ecologist Charles Elton’s “functional” concept of the niche and of the notion of function implicitly associated with it. It does so in part by situating Elton’s niche concept within the broader context of the “functionalist-interactionist” approach to ecology he introduced, and in relation to his views on the relationship between ecology and evolution. This involves criticizing the common claim that Elton’s idea of species as fulfilling functional roles within ecological communities committed him to an (...) idea of communities as units of selection. While such a claim implicitly attributes to Elton an understanding of function along the lines of the selected-effects theory of function advocated by many biologists and philosophers of biology, Elton’s use of the niche concept, I maintain, involves an understanding of function more along the lines of alternative nonselectionist theories such as the causal-role, goal-contribution, and organizational theories. I also briefly discuss how ecologists after Elton also tend to have typically adopted a nonselectionist understanding of the function concept, similar to his. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.1 (2002) 124-137 [Access article in PDF] Katz's Problematic Dualism and Its "Seismic" Effects on His Theory Wayne Ouderkirk There is much to admire in Eric Katz's Nature as Subject. 1 Many aspects of his theory strongly resonate with dominant themes in environmental ethics and with my own theoretical predilections. In addition, he applies his theory to several major environmental issues (ecological restoration and (...) the Amazon rainforest, to name two), simultaneously testing it against other views and tracing out its implications. Impressive, non-ivory tower philosophizing. The array of issues he covers is impressive too, from the place of animal rights in an environmental ethic to the relation between environmental destruction and genocide; from the tension between holism and the rights of individuals to intrinsic value; from anthropo- centrism to Judaism and the environment; from the history of environmental thought to the convergence hypothesis. And more.In light of this tremendous range and of my own attraction to such of his major themes as ecocentrism, it might seem unappreciative to criticize, [End Page 124] to dissent. But despite all the positives I find in Katz's writings, I also find faults there, faults which, when pressed, cause major fissures in the whole. The central, major problem is Katz's dualism; and I think it ultimately undoes his whole theory, since it is so intimately connected with the other parts. Within Katz's own essays, there are, I think, resources to begin a reconstruction; but as with any other such effort, the first task is to discard the parts that are no longer useable. Before doing so, however, I want to review some positive aspects of Katz's theory, lest I convey the mistaken impression that my initial praise for his work is mere courtesy. The Solid Geological Features To begin with the most general: Katz's concern for, commitment to the natural world is obvious to any reader. He suffuses every essay with a determination to seek out clear and cogent philosophical rationales for its protection. More important perhaps is his obvious personal connection to that world. His references to Fire Island's deer and beaches, for example, amply demonstrate what the rest of his writings imply: that his theoretical efforts are more than armchair musings about a current philosophical issue. Katz's efforts are both professional and passionate.On a more specifically philosophical level, I regard his anti-anthropocentrism as a significant strength. Though one can, of course, be an anthropocentrist and be an environmental philosopher—Bryan Norton (1984) and Eugene Hargrove (1989) come to mind—I think Katz's arguments showing that anthropocentric views can only offer contingent justifications for protecting the environment are cogent and valid (3-11). An important part of those arguments is Katz's demonstration that different theories in environmental philosophy do indeed result in different environmental policies. In other words, Katz offers a strong counterargument to Norton's convergence hypothesis (Norton 1991), the idea that, given environmentalists' shared commitment to the environment, the various philosophical theories offered in justification of that commitment will converge on similar policy recommendations (149 ff.). I agree with Katz's refutation of that hypothesis, and I offer my critique of his theory because I think that theory's faults will ultimately undermine sound policies.Another big asset of Katz's theory is his communitarianism, the idea that we are part of an ecological community, an ecosystem, to which we have moral obligations. Not surprisingly to anyone familiar with environmental ethics, the source of this idea is Aldo Leopold's Land Ethic (Leopold 1966), [End Page 125] which has been debated, analyzed, praised, and critiqued more than extensively in the literature. Katz pretends to no originality here; he simply adopts and vigorously defends an ecocentric ethic that counts the integrity, stability, and beauty of the system—including, not incidentally, abiotic components—as central criteria limiting human interference with nature. Unlike, for example, the total ecocentrism of J. Baird Callicott's (1980) early writing, however, Katz tempers his communitarianism with another dimension, qualifying his holistic... (shrink)

I argue that a reasonable understanding of Leopold’s ‘Land Ethic’ is one that identifies possession of health as being a sufficient condition for moral consideration. With this, Leopold extends morality not only to biotic wholes, but to individual organisms, as both can have their health undermined. My argument centers on explaining why Leopold thinks it reasonable to analogize ecosystems both to an organism and to a community: both have a health. My conclusions undermine J. Baird Callicott’s rhetorical dismissal (...) of the organism analogy’s importance, a dismissal crucially serving his thesis that Leopoldians should hold community membership necessary for moral standing.

In Defense of the Land Ethic: Essays in Environmental Philosophy brings into a single volume J. Baird Callicott’s decade-long effort to articulate, defend, and extend the seminal environmental philosophy of Aldo Leopold. A leading voice in this new field, Callicott sounds the depths of the proverbial iceberg, the tip of which is “The Land Ethic.” “The Land Ethic,” Callicott argues, is traceable to the moral psychology of David Hume and Charles Darwin’s classical account of the origin and (...) evolution of Hume’s moral sentiments. Leopold adds an ecological vision of organic nature to these foundations. How can an evolutionary and ecological environmental ethic bridge the gap between is and ought? How may wholes—species, ecosystems, and the biosphere itself—be the direct objects of moral concern? How may the intrinsic value of nonhuman natural entities and nature as a whole be justified? In addition to confronting and resolving these distinctly philosophical queries, Callicott engages in lively debate with proponents of animal liberation and rights—finally to achieve an integrated theory of animal welfare and environmental ethics. He critically discusses the land ethic that is alleged to have prevailed among traditional American Indian peoples and points toward a new and equally revolutionary environmental aesthetic. (shrink)

Photo by Jonathan Ford on Unsplash ABSTRACT Since 2008, an average of twenty million people per year have been displaced by weather events. Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. This paper analyzes the idea of expanding a duty to rescue to climate migration. We address who should have (...) the duty and to whom the duty should extend. The paper discusses ways to define and apply the duty to rescue as well as its limitations, arguing that it may take the form of an ethical duty to prepare. INTRODUCTION Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. Examples of circumstances range from person-to-person intimate rescue to saving those in poverty, even in distant parts of the world.[1] Since 2008, an average of twenty million people per year have been displaced by weather events.[2] Circumstances like being thrust from homes under the threat of fire, mudslide, and flooding vary greatly from long-term changes like land becoming too arid for crops or temperatures increasing annually gradually pushing up the number of heat-related deaths, with the area slowly becoming uninhabitable. Imminence in fleeing affects resettling and need for rescue with important implications for how the duty to rescue might apply. This paper reevaluates the ethical framing of the duty to rescue and, while it is arguably a stretch, applies it to climate migration. Climate migration has become common and is expected to increase due to rises in sea level, increases in weather events that make areas uninhabitable, and changes to land that preclude farming or other necessary land uses. We argue that a duty to rescue may help highlight who has moral obligations to whom. Because the problem is so large in scope, we suggest a change in the ethical limits to humans' duty to rescue other humans who are in distress. We imagine an expansion or extension of the duty to rescue to meet some of the basic needs created by climate migration. Yet how it should expand, and how much depend on ethical framing and practical limitations. l. Expanding the Geographical Boundaries Two commonly recognized emergencies, Hurricane Katrina in the case of weather events and the current COVID-19 pandemic, provide a historical and current backdrop to evaluate ethical obligations as more disasters displace people. A significant reassessment of the ethical scope of an obligation to rescue in the case of weather events will be limited by the ability to render aid to those in distress in the case of a planet-wide weather catastrophe. The problems may overwhelm the ability to rescue or the reasonableness of attempting rescue. The extent of the moral obligation borne by humans to other humans in the case of a weather event has been largely defined by its locality and limited geographic influence. Whether we are imagining the scope of ethical obligation in the case of hurricane, flood, tornado, drought, or wildfire events, the perceived ethical obligation is significantly defined by the limited impact of these weather events on people outside the zone of the weather event's direct impact, yet close to that zone. A hurricane affecting New Orleans will not have immediate impact on the residents of California or even those on the northeast coast of the United States until a later time. Wildfires in the Pacific Northwest do not impair the ability of those in the rest of the country to come forward with assistance. But as climate migration crosses international borders, and climate events occur simultaneously in many regions, a more expansive duty to rescue may provide the ethical impulse to help those who live afar or migrate long distances. In this respect, the need for help in the event of widespread climate migration due to global warming is more like a pandemic than a weather event. Its broad impact area diminishes the capability of nearly the entire balance of the human population to help due to those populations' awareness that they will, in short order, have the same need for the same resources, from the same cause. Those living near current flood zones may find their historically safe havens are also a flood zone. Those previously best positioned to rescue may find themselves also needing to relocate. Thus, we may observe the need for new rescuers. ll. The Rule of Rescue The Rule of Rescue as defined by Al Jonsen describes the moral impetus or knee jerk reaction to save identifiable people facing death.[3] A duty to rescue has since been expanded beyond imminent death and beyond the near and identifiable. But there are limitations. For example, by most accounts, the ethical duty tends not to require extreme bodily risk or financial depletion. In comparing Good Samaritans to humanitarians, Scott M. James argues the duty to rescue arises from unique dependence, but the ethical obligation to help strangers through humanitarian aid is of a different nature.[4] The wrongness of failing to help is arguably more egregious when one is in a unique position to help. Like in the tragedy of the commons, where there is no unique positioning, when the global community is called upon to help, each individual in it may feel less obliged to do so. Climate migration falls in between—it requires helping strangers, yet it may move forward without anyone seeing themselves as uniquely positioned to help until those strangers become part of communities, at which time, there may be more moral justification to help a community member in need. Generally, arguments about Good Samaritans hinge on extraordinary acts, praiseworthy because they are acts of compassion, not obligation. Now all US states have Good Samaritan laws[5] which protect helpers from liability for help gone wrong or for a failure to succeed once engaged in an act of rescue. Extraordinary help as a moral good is thus somewhat encouraged through legal protection, but not imposed. Conversely, jobs like firefighting, search and rescue, and emergency medical care tend to oblige employees to take on risks that would be extraordinary if undertaken by the average bystander, yet they are rendered ordinary rescue as part of the job. Three states, Minnesota, Rhode Island, and Vermont have a broad duty to rescue, adding legal considerations to an otherwise moral conundrum. The laws do not require bystanders to take on risk for the sake of rescuing strangers.[6] The moral duty will require looking beyond law, but it is unclear how the moral duty to rescue should be distributed in the case of climate migration. A bare minimum would prevent taking advantage of newcomers, paying sub-minimum wage, and discriminating against them. Yet such a minimum is hardly rescue. lll. An Ethical Rather than Legal Duty The difficulty in defining the duty to rescue as a legal obligation is that it is difficult to determine the extent of risk a rescuer ought to be required to take. The nature of this ethical duty is also arguably tied to the experiences of both the rescuer and the rescued. There are subjective aspects like what someone perceives as a danger that make it difficult to write enforceable laws requiring rescue. It is one thing to expect a rescuer to step into several inches of relatively warm water to lift a person lying face down in a pond and enable them to breathe. It is something altogether different to expect that rescuer to dive into frigid water and attempt to extricate someone trapped in a submerged automobile. As the legal philosopher H.L.A. Hart observed, it is always easier to define application of the core intention of any rule, whether law or ethical norm. It is more difficult to create legal certainty about how the law applies to what he described as “penumbra circumstances”. In the case of a hurricane, it is easier to define what surplus resources are available in areas geographically remote from the impact of the storm and demand, as a moral obligation, that those nearby but outside the area provide assistance. It is more difficult to obligate people, organizations, or governments to supply a quantity of medication or some number of ventilators to an adjacent community when they expect to imminently need them for their own community. In the early stages of climate migration, the ethics of extreme weather event assistance, a common application of the duty to rescue, will be useful and appropriate. The rising sea levels first experienced by island nations in the South Pacific[7] will not render those living in other coastal communities, those with greater available “high ground”, unable to supply resources to those in need. But when sea level rise and climate change affect more communities simultaneously, albeit in varying degree, the task of defining what response is ethically obligatory becomes increasingly complicated. Pinpointing the obligations of those communities which are resource rich to those communities which are resource deprived, and of those partly affected to those more severely affected may become necessary. The limitations of the traditional duty to rescue could expand to meet the needs. lV. Contribution to the Problem Many argue that the duty to rescue may depend on any appropriate claim of those needing rescue. One issue is whether preferential claims among those who can identify the source of the harm should call for a greater duty or whether everyone in need should be approached as like candidates for rescue, shaping the duty as equal across those on the receiving end. As climate change does have human-made causes, there are strong arguments to impose a greater ethical duty on any entity that caused the climate-related problems leading to the mass exodus. While the global north is often implicated in pollution that causes migration, industries like energy, transportation, and agriculture are tied to climate change and associated with significant greenhouse gas emissions.[8] Practices like directing agriculture to less sustainable single crop growth generally made land less farmable. Yet it is difficult to place blame and identify specific causal relationships as most migration is due to many factors. A movement toward greater accountability can be reframed as a greater duty to rescue, a duty to engage in the extraordinary. The fossil fuel industry, for example, should have a larger obligation than the average person. Similarly, some may argue anyone unjustly enriching themselves while contributing to climate change or people who over-consume have an elevated duty to rescue.[9] Climate change lawsuits demonstrate an eagerness to hold governments and corporations accountable, despite difficulty proving causation. V. The Most Vulnerable One ethical dimension of climate migration that remains unexplored is how a duty to rescue applies to vulnerable populations who stand to be left behind or unable to migrate without assistance. Researchers from the Global North working across the Global South are increasingly observing the phenomenon of ethics dumping, where the research ethics of some countries are imposed on research subjects in other countries.[10] In that vein, rescuers should be careful not to impose unwelcome cultural standards or exploit people who are in the process of migrating. There is a gap in discussions reflecting voices that have been left out. The duty to rescue is incomplete without an attempt to understand the ethical experiences of those being rescued. The actual people affected by climate migration who are the least likely to have the means to migrate, or to do so without extreme hardship, should have a voice informing the global community including those in a position to carry out rescue. People who have the means and are young and healthy may easily make decisions to avoid the catastrophic consequences that climate migration brings. However, what about those who are left behind? For example, especially recognizing cultural differences, the homeless community, disabled community, refugees, the elderly community, and women[11] and children may suffer differently and call for more attention. In some parts of the world, human rights are severely constrained. An ethical duty to rescue, with many considerations and variables, may be more justified in the case of those most in need. As climate migration continues and increases significantly, it may be reasonable to ask the local and global community to focus on those least well positioned to migrate successfully. In this context, the use of phenomenology to understand the lived experiences of those migrating, sometimes termed “ethical experiences”, may help flesh out how a duty to rescue takes shape. The discussion of duty and obligation requires an articulation of the ethical experiences (how the local community in need of rescue views the proposed rescue). Then, the obligation to interpret the duty as ‘one shall not’ or ‘one must’ can be focused on the migrants’ needs rather than the rescuers’ feelings of obligation.[12] A revised theory of the duty to rescue taking into account the asymmetrical experiences of communities involved could ensure that the needs of people whose living situations, gender, ethnicity, age, or race impact their ability to even begin the migration process are considered. In this discussion, the rescuing is directed toward communities /collectives of persons migrating, whether at once or across a period of time. Often, the climate migrant may not be in a state to articulate the nature of this event when it happens, given its subjective proximity. Yet, when communities are given the space and opportunity to articulate their shared values, the ethical action of rescue derives its meaningfulness from the community rather than the rescuers. In other words, allowing climate migrants to explain their feelings can add complexity to what some see as a binary receiver-giver (of rescue) dynamic. This is necessary because the concept of vulnerable populations is fraught with problematic assumptions. There have been various definitions and criteria to determine what would constitute vulnerable populations.[13] For example, the United Nations Framework Convention on Climate Change[14] identifies and assesses vulnerable populations. These criteria may be helpful. However, they do not provide the full picture. Rather than identifying categorical criteria of vulnerable populations, engaging with people who are experiencing climate migration and listening to their current experiences and concerns helps determine need. Knowing what people need may prevent the kneejerk reaction to label people who are quite resilient yet have appropriate needs “vulnerable”. Proceeding with caution is important because the duty to rescue has hierarchical underpinnings of "us" and "them." Often when people swoop in to save, there are good and bad consequences of the intervention. We should proceed with caution because often the helper misses the actual needs of those in need. The only way to combat this would be to make sure that people are empowered to inform those agencies that are able to help. In addition to more practical approaches, large scale oral histories could allow those who have migrated already to share their experiences. It would be important to capture the lived experiences of people who are already experiencing the consequences of climate migration or of other migration like that due to political or economic extreme events. These experiences could shape our analysis of whether people in fact wish for rescue. If so, further conversations can determine best actions as well as give important insight into what resources might be necessary to empower people now and in the future. Vl. A Duty to Rescue as a Duty to Prepare If we view Good Samaritans as going above and beyond, then a duty to rescue, something ethically compelled, must bring rescue out of the framework of charity and place it in the context of humanity and obligations. Such a view would also support expanding the geographical reach of the otherwise more proximate duty. The duty may be stronger and take shape in a more workable way if it applies to preparing places expecting to see an influx of people due to climate migration and to helping those most in need. The duty may arise out of expectations of what type of community the place welcoming those migrating due to climate should be—does it want to offer good housing, schooling, and medical care as well as economic opportunity to new people? And if so, at what cost, or with which risks? If the newcomers are viewed as community members rather than strangers, a model of acceptance may lead to better preparation. Some considerations like whether the actions will reasonably help the persons in need of rescue[15] will shape the application of a duty to rescue in the context of climate migration. Similarly, ensuring that people have the chance to articulate their values may help communities support the newcomers. New relationships should not be defined as migrant and rescuer. Voluntariness in participation and not forcing any action deemed rescue would help ensure the human rights of those migrating. In the United States, President Biden issued an executive order addressing impending climate migration steeped in a duty to prepare by making plans for resettlement and to address the impact of climate migration.[16] Vll. At What Risk? As we investigate the ethical obligations to meet even basic needs, we must also ask what level of risk is ethically compelled. There is an extraordinary need to integrate newcomers successfully, but it is difficult to stretch an ethical duty to rescue to require all the prerequisites for successful climate migration. Even defining success would create deep ethical arguments. As observed in almost all migrations, extraordinary charitable acts may be the key to success, while an ethical duty to rescue must try to require the important government and community-based basics and ensuring respect for human rights. That is, the migrating people should be rescued from circumstances that contradict basic human rights. Rather than comparing communities to bystanders, mere places where people will arrive and need to hash out how to find housing, jobs, education, and opportunity, a duty of preparation may be the key to rescue those disenfranchised by migration. There are cultural, personal, physical, psycho-social, and geopolitical issues surrounding how to best help those needing to permanently relocate. Ethics arguments will certainly range from “do nothing”, which may fail people, to “do everything”, which could waste taxpayer money in futile over-preparation while failing to actually help. Communities must avoid planning exclusively for one scenario only to have it not take place. Striking the balance, a duty to rescue as it could apply to climate migration should set goals of societal integration, and providing the basics like education, housing, food, health care, and job opportunity, the precursors to flourishing. Recommending the extraordinary, morally preferred but perhaps not compulsory, when charitable actors are participating, or when wrongdoers are compensating, may be more workable than seeing the duty to rescue as compelling people or local governments to take on significant financial and personal risk for newcomers. While humanitarian ethics supports helping everyone, it is likely that people who resettle in advance of a need to flee will find themselves with more choices and opportunities. Help is warranted for those with more dire needs. Preparing for them may do just that. Vlll. Rescue Prior to Migration and Rescue in the Process of Resettlement The duty to enable the migration in the first-place hints to the inadequacy of a duty to prepare. The traditional duty to rescue perhaps steps in if rescue looks like those geographically just out of harm's way rescuing those in danger. That resembles the traditional moral requirement, or duty to rescue according to the Rule of Rescue. Humanitarian aid typically provided by many institutions makes sense and is in place, although financial support for additional humanitarian aid is always needed. Despite having moved to purportedly more capable communities, migrant communities may be able to develop more egalitarian orders of living. Rather than continually being identified as having been rescued, it is important to make sure people keep or make social ties during and after migration. Immigrants often face social isolation.[17] Small shifts in gestural language also have the potential to welcome people and show they are valued. For instance, some migrants may not like questions like “Where are you from?” and “What brings you here?” as they emphasize differences over fitting in. CONCLUSION The ethical duty to rescue should be expanded to better match those in need of relocation with a welcome environment and the resources needed to achieve success and fully integrate socially and culturally. Expanding a dialogue that includes the voices of people who have recently migrated whether due to violence, poverty, or climate, could properly frame the extent of the duty. If we are to apply the duty of rescue to climate migration, rescuers should avoid labeling people vulnerable, dependent, or needy, although there is reason to focus on those whose needs are the most dire. A soft duty to rescue people during the course of climate migration can come in the form of preparation. People will need help finding housing, education, access to food, and employment. Ultimately, to help them help themselves may be the best goal. While the obligations should be borne differently by people, whether due to a special responsibility, or a special relationship that creates a clearer duty, the global community must prepare for its role in rescuing those displaced by climate events. By helping those displaced at the start of the climate migration process according to a more commonly held notion of the duty to rescue, and by preparing to incorporate newcomers successfully according to an expanded duty to rescue, effectively a duty to prepare, countries that take on climate refugees may find themselves rewarded by the cultural diversity and workplace talents that people bring. A duty to those at a distance is a reasonable expansion of the duty to rescue. But what one ought to do in the global community varies somewhat from the traditional Rule of Rescue. - [1] Singer, P.

The United Nations Educational, Scientific and Cultural Organization recently declared transhumance pastoralism as an Intangible Cultural Heritage of Humanity. The notion of heritage seeks to recognize the culture behind the seasonal grazing movements along herding routes, between distant and dissimilar ecosystems. The pastoral families move with their herds from pasturelands used during the winter (winter-lands) to areas pastured during the summer (summer-lands). Whereas this is a key step towards the recognition of the cultural dimension associated to this ancient practice, a (...) relevant feature of transhumance pastoralism is its strong linkage with environmental dynamics. This activity developed in a spatiotemporal and co-evolutionary trajectory, which gave rise to a pastoral territory. A territory is the union or linkage of a meaning with a specific place, that is, the space that is appropriated and valued, both symbolically and instrumentally, by human groups. Hence, the pastoral territory represents the socio-ecological system that integrates a pastoral-based community with the natural environment that it inhabits. We propose a co-evolutionary approach to analyzing some key attributes of transhumant pastoralism, which modulate the socio-ecological interdependence. Based on a study case from Northwest Patagonia, Argentina, we identified and characterized seven attributes: (I) mobility, (II) connectivity, (III) temporal synchrony, (IV) local interdependence, (V) local ecological knowledge, (VI) adaptive capacity legacy, and (VII) mixture of land tenure. We discuss these features as examples that represent keystone socio-ecological attributes for the recognition of transhumant pastoral territories as a biocultural heritage. (shrink)

It is a matter of fact that Europe is facing more and more crucial challenges regarding health and social care due to the demographic change and the current economic context. The recent COVID-19 pandemic has stressed this situation even further, thus highlighting the need for taking action. Active and Assisted Living technologies come as a viable approach to help facing these challenges, thanks to the high potential they have in enabling remote care and support. Broadly speaking, AAL can be referred (...) to as the use of innovative and advanced Information and Communication Technologies to create supportive, inclusive and empowering applications and environments that enable older, impaired or frail people to live independently and stay active longer in society. AAL capitalizes on the growing pervasiveness and effectiveness of sensing and computing facilities to supply the persons in need with smart assistance, by responding to their necessities of autonomy, independence, comfort, security and safety. The application scenarios addressed by AAL are complex, due to the inherent heterogeneity of the end-user population, their living arrangements, and their physical conditions or impairment. Despite aiming at diverse goals, AAL systems should share some common characteristics. They are designed to provide support in daily life in an invisible, unobtrusive and user-friendly manner. Moreover, they are conceived to be intelligent, to be able to learn and adapt to the requirements and requests of the assisted people, and to synchronise with their specific needs. Nevertheless, to ensure the uptake of AAL in society, potential users must be willing to use AAL applications and to integrate them in their daily environments and lives. In this respect, video- and audio-based AAL applications have several advantages, in terms of unobtrusiveness and information richness. Indeed, cameras and microphones are far less obtrusive with respect to the hindrance other wearable sensors may cause to one’s activities. In addition, a single camera placed in a room can record most of the activities performed in the room, thus replacing many other non-visual sensors. Currently, video-based applications are effective in recognising and monitoring the activities, the movements, and the overall conditions of the assisted individuals as well as to assess their vital parameters. Similarly, audio sensors have the potential to become one of the most important modalities for interaction with AAL systems, as they can have a large range of sensing, do not require physical presence at a particular location and are physically intangible. Moreover, relevant information about individuals’ activities and health status can derive from processing audio signals. Nevertheless, as the other side of the coin, cameras and microphones are often perceived as the most intrusive technologies from the viewpoint of the privacy of the monitored individuals. This is due to the richness of the information these technologies convey and the intimate setting where they may be deployed. Solutions able to ensure privacy preservation by context and by design, as well as to ensure high legal and ethical standards are in high demand. After the review of the current state of play and the discussion in GoodBrother, we may claim that the first solutions in this direction are starting to appear in the literature. A multidisciplinary debate among experts and stakeholders is paving the way towards AAL ensuring ergonomics, usability, acceptance and privacy preservation. The DIANA, PAAL, and VisuAAL projects are examples of this fresh approach. This report provides the reader with a review of the most recent advances in audio- and video-based monitoring technologies for AAL. It has been drafted as a collective effort of WG3 to supply an introduction to AAL, its evolution over time and its main functional and technological underpinnings. In this respect, the report contributes to the field with the outline of a new generation of ethical-aware AAL technologies and a proposal for a novel comprehensive taxonomy of AAL systems and applications. Moreover, the report allows non-technical readers to gather an overview of the main components of an AAL system and how these function and interact with the end-users. The report illustrates the state of the art of the most successful AAL applications and functions based on audio and video data, namely lifelogging and self-monitoring, remote monitoring of vital signs, emotional state recognition, food intake monitoring, activity and behaviour recognition, activity and personal assistance, gesture recognition, fall detection and prevention, mobility assessment and frailty recognition, and cognitive and motor rehabilitation. For these application scenarios, the report illustrates the state of play in terms of scientific advances, available products and research project. The open challenges are also highlighted. The report ends with an overview of the challenges, the hindrances and the opportunities posed by the uptake in real world settings of AAL technologies. In this respect, the report illustrates the current procedural and technological approaches to cope with acceptability, usability and trust in the AAL technology, by surveying strategies and approaches to co-design, to privacy preservation in video and audio data, to transparency and explainability in data processing, and to data transmission and communication. User acceptance and ethical considerations are also debated. Finally, the potentials coming from the silver economy are overviewed. (shrink)

The structuring of our environment to provide cues and reminders for ourselves is common: We leave notes on the fridge, we have a particular place for our keys where we deposit them, making them easy to find. We alter our world to streamline our cognitive tasks. But how did hominins gain this capacity? What pushed our ancestors to structure their physical environment in ways that buffered thinking and began the process of using the world cognitively? I argue that the capacity (...) to engage in these behaviours is a by-product of increased tool investment and tool curation, which in turn was necessary because of increasingly heterogeneous environments. The minute tools are carried and cared for, they begin to undergo selection for added functions, becoming available as cognitive primers and as signals. I explore the trajectory of this co-evolutionary feedback loop of hominins and their tools, and demonstrate the role tools have in shaping our thinking. (shrink)

Are ecosystems morally considerable-that is, do we owe it to them to protect their “interests”? Many environmental ethicists, impressed by the way that individual nonsentient organisms such as plants tenaciously pursue their own biological goals, have concluded that we should extend moral considerability far enough to include such organisms. There is a pitfall in the ecosystem-to-organism analogy, however. We must distinguish a system’s genuine goals from the incidental effects, or byproducts, of the behavior of that system’s parts. Goals seem (...) capable of giving rise to interests; byproducts do not. It is hard to see how whole ecosystems can be genuinely goal-directed unless group selection occurs at the community level. Currently, mainstream ecological and evolutionary theory is individualistic. From such a theory it follows that the apparent goals of ecosystems are mere byproducts and, as such, cannot ground moral considerability. (shrink)
