INTRODUCTION The appeal to teleological principles of explanation within the body of natural science has had an unfortunate history. ...

In this volume, the authors discuss what practical contributions ecology can and can't make in applied science and environmental problem solving. In the first section, they discuss conceptual problems that have often prevented the formulation and evaluation of powerful, precise, general theories, explain why island biogeography is still beset with controversy and examine the ways that science is value laden. In the second section, they describe how ecology can give us specific answers to practical environmental questions posed in individual case (...) studies, and argue for a new way to look at scientific error. A case study using the Florida panther is examined in the light of these findings. (shrink)

This book is a sustained examination of issues in the philosophy of ecology that have been a source of controversy since the emergence of ecology as an explicit scientific discipline. The controversies revolve around the idea of a balance of nature, the possibility of general ecological knowledge and the role of model-building in ecology. The Science of the Struggle for Existence is also a detailed treatment of these issues that incorporates both a comprehensive investigation of the relevant ecological literature and (...) the development of an explicit theoretical framework in the philosophy of science. It addresses issues in the philosophy of ecology that are of particular importance for the deployment of ecology in the solution of environmental problems. It will have a cross-disciplinary appeal and will interest students and professionals in science, the philosophy of science, and environmental studies as well as policy-makers. (shrink)

How shall we understand apparently teleological systems? What explains their persistence and their plasticity? Here I argue that all seemingly goal-directed systems—e.g., a food-seeking organism, human-made devices like thermostats and torpedoes, biological development, human goal seeking, and the evolutionary process itself—share a common organization. Specifically, they consist of an entity that moves within a larger containing structure, one that directs its behavior in a general way without precisely determining it. If so, then teleology lies within the domain of the theory (...) of compositional hierarchies. (shrink)

A community, for ecologists, is a unit for discussing collections of organisms. It refers to collections of populations, which consist (by definition) of individuals of a single species. This is straightforward. But communities are unusual kinds of objects, if they are objects at all. They are collections consisting of other diverse, scattered, partly-autonomous, dynamic entities (that is, animals, plants, and other organisms). They often lack obvious boundaries or stable memberships, as their constituent populations not only change but also move in (...) and out of areas, and in and out of relationships with other populations. Familiar objects have identifiable boundaries, for example, and if communities do not, maybe they are not objects. Maybe they do not exist at all. The question this possibility suggests, of what criteria there might be for identifying communities, and for determining whether such communities exist at all, has long been discussed by ecologists. This essay addresses this question as it has recently been taken up by philosophers of science, by examining answers to it which appeared a century ago and which have framed the continuing discussion.

In this essay I first provide an analysis of various community concepts. Second, I evaluate two of the most serious challenges to the existence of communities—gradient and paleoecological analysis respectively—arguing that, properly understood, neither threatens the existence of communities construed interactively. Finally, I apply the same interactive approach to ecosystem ecology, arguing that ecosystems may exist robustly as well. ‡I would like to thank to the participants at the Ecology and Environmental Ethics Conference at the University of Utah, the Philosophy (...) of Ecology Conference hosted by the University of Brisbane, and those participants in a session at the Philosophy of Science Association Meeting in Vancouver, British Columbia for helpful discussions of this essay.

In this essay, I argue that uneliminated idealizations pose a serious problem for scientific realism. I consider one method for “de-idealizing” models—robustness analysis. However, I argue that unless idealizations are eliminated from an idealized theory and robustness analysis need not do that, scientists are not justified in believing that the theory is true. I consider one example of modeling from the biological sciences that exemplifies the problem.

Philosophy of ecology has been slow to become established as an area of philosophical interest, but it is now receiving considerable attention. This area holds great promise for the advancement of both ecology and the philosophy of science. Insights from the philosophy of science can advance ecology in a number of ways. For example, philosophy can assist with the development of improved models of ecological hypothesis testing and theory choice. Philosophy can also help ecologists understand the role and limitations of (...) mathematical models in ecology. On the other side, philosophy of science will be advanced by having ecological case studies as part of the stock of examples. Ecological case studies can shed light on old philosophical topics as well as raise novel issues for the philosophy of science. For example, understanding theoretical terms such as “biodiversity” is important for scientific reasons, but such terms also carry political importance. Formulating appropriate definitions for such terms is thus not a purely scientific matter, and this may prompt a reevaluation of philosophical accounts of defining theoretical terms. We consider some of the topics currently receiving attention in the philosophy of ecology and other topics in need of attention. Our aim is to prompt further exchange between ecology and philosophy of science and to help set the agenda for future work in the philosophy of ecology. The topics covered include: the role of mathematical models, environmental problem formulation, biodiversity, and environmental ethics. (shrink)

Value claims about ecological entities, their functionality, and properties take center stage in so-called “ecological” ethical and aesthetic theories. For example, the claim that the biodiversity in an old-growth forest imbues it with “value in and for itself” is an explicit value claim about an ecological property. And the claim that one can study “the aesthetics of nature, including natural objects...such as ecosystems” presupposes that natural instances of a type of ecological entity exist and can be regarded as more or (...) less aesthetically valuable. My discussion below will bear wide implications for how claims like... (shrink)

Environmental protection isn't what it used to be. During the 1960s and 1970s, environmentalists enacted a legislative agenda that seems like a dream today: statutes like the Clean Air and Clean Wa...

First published in 1992, The Way is Edward Goldsmith's magnum opus. In it, he proposes that the stability and integrity of humans depend on the preservation of the balance of natural systems surrounding the individual--family, community, society, ecosystem, and the ecosphere itself. Portraying life processes and ecological thinking as holistic, Goldsmith calls for a paradigm shift away from the reductionist approach of modern science. The basic belief in the whole was at the heart of the worldview of primal, earth-oriented societies, (...) as manifested by the Tao of the ancient Chinese, the R'ta of Vedic India, the Asha of the Avestas, and the Sedaq of the tribal Hebrews. The Way was the path taken to maintain the critical order of the cosmos. Echoing the way of traditional cultures, Goldsmith presents an all-embracing, coherent worldview that promotes more harmonious and sustainable practices capable of satisfying real biological, social, ecological, and spiritual needs. Revised to include a glossary, index, bibliographic notes, and several updated chapters, this is a major work by one of our boldest and most promising thinkers. (shrink)

Environmental advisory institutions around the world operate under the assumption that theoretical ecological models (TEMs) can guide decision-making about environmental policy and natural resource management. At the same time, leading ecologists and philosophers continue to point out that it is unclear exactly how such models can usefully inform such decision-making. Much critical debate about whether and how ecology can inform practical decisions centers on confusions that are due to the fact that the workings of TEM-based research is poorly understood outside (...) ecology. This essay addresses this issue by clarifying: what TEMs are; what limitations ecologists admit such models have; and in what general ways TEM-based analyses can inform and enable decision-making in environmental policy and resource management in spite of those limitations.

Ecologists use a remarkable range of methods and techniques to understand complex, inherently variable, and functionally diverse entities and processes across a staggering range of spatial, temporal and interactive scales. These multiple perspectives make ecology very different to the exemplar of science often presented by philosophers. In Philosophical Foundations for the Practices of Ecology, designed for graduate students and researchers, ecology is put into a new philosophical framework that engages with this inherent pluralism while still placing constraints on the ways (...) that we can investigate and understand nature. The authors begin by exploring the sources of variety in the practice of ecology and how these have led to the current conceptual confusion. They argue that the solution is to adopt the approach of constrained perspectivism and go on to explore the ontological, metaphysical, and epistemological aspects of this position and how it can be used in ecological research and teaching"--Provided by publisher.

This essay explores two strategies of inquiryin ecological science. Ecologists may regardthe sites they study either as contingentcollections of plants and animals, therelations of which are place-specific andidiosyncratic, or as structured systems andcommunites that are governed by general rules,forces, or principles. Ecologists who take thefirst approach rely on observation, induction,and experiment – a case-study or historicalmethod – to determine the causes of particularevents. Ecologists who take the secondapproach, seeking to explain by inferringevents from general patterns or principles,confront four conceptual obstacles (...) which thisessay describes. Theory in ecology must (1)define and classify the object it studies,e.g., the ecosystem, and thus determine theconditions under which it remains the ``same''system through time and change. Ecologistsmust (2) find ways to reject as well as tocreate mathematical models of the ecosystem,possibly by (3) identifying efficient causes ofecosystem organization or design. Finally,ecologists will (4) show ecological theory canhelp solve environmental problems both inpristine and in human-dominated systems. Afailure to solve – or even to address – theseobstacles suggests that theoretical ecology maybecome a formal science that studies themathematical consequences of assumptionswithout regard to the relation of theseassumptions to the world.

In this essay, I consider three philosophical issues that arise in the environmental sciences. First, these sciences depend on mathematical models and simulations which are highly idealized and are coupled with very uncertain data. Why should we trust these models and simulations? Second, in standard hypothesis testing, the burden of proof is in favor of the null hypothesis which claims some causal factor has no effect. The alternative hypothesis is accepted only when the likelihood of the null hypothesis is very (...) low. Recently, some have argued that we should minimize Type II errors (not rejecting a false null) rather than Type I errors (rejecting a true null) given the environmental risks involved. I consider arguments for shifting this burden of proof when possible environmental harms are significant. Finally, in debates over global climate change, much is made of the apparent consensus concerning the effects of human induced greenhouse gas emissions on average surface temperatures. However, scientific methods are structured around dissent and criticism. Is consensus-based science orthogonal are even harmful to science? (shrink)

Larry Wright's analysis of teleological description of goal-directed behavior, though ingenious and insightful, errs in the following ways: it incorrectly claims that intentional human action exhibits consequence-etiology, making it impossible, contrary to his claim, for reference to consequence-etiology to be metaphorically transmitted to teleological descriptions of nonhuman behavior; it does not remove the threat of reverse causation for nonhuman behavior; it assumes in the face of contrary evidence that reference to purpose drops out in metaphorical extension; and it cannot account (...) for unrequired behavior directed toward impossible goals.

Ecologists attempt to understand the diversity of life with mathematical models. Often, mathematical models contain simplifying idealizations designed to cope with the blooming, buzzing confusion of the natural world. This strategy frequently issues in models whose predictions are inaccurate. Critics of theoretical ecology argue that only predictively accurate models are successful and contribute to the applied work of conservation biologists. Hence, they think that much of the mathematical work of ecologists is poor science. Against this view, I argue that model (...) building is successful even when models are predictively inaccurate for at least three reasons: models allow scientists to explore the possible behaviors of ecological systems; models give scientists simplified means by which they can investigate more complex systems by determining how the more complex system deviates from the simpler model; and models give scientists conceptual frameworks through which they can conduct experiments and fieldwork. Critics often mistake the purposes of model building, and once we recognize this, we can see their complaints are unjustified. Even though models in ecology are not always accurate in their assumptions and predictions, they still contribute to successful science. (shrink)

Ecology has been used frequently by social scientists as a source of theoretical models, and biological ecologists have often applied their theory to human populations. Several problems have attended these cross-disciplinary enterprises, including inappropriate uses of teleological models and a failure by both biologists and social scientists to understand the theoretical implications of culture and technology for ecological models. Attention to these problems will increase the applicability of ecological theories in the social sciences.

I contrast metaphysical implications from physics and ecology and compare them through two concepts, the field, primary in physics and borrowed by ecology, and wholeness, postulated in ecology and borrowed by physics. I argue that several implications from physics are unacceptably reductive or erroneous and identify an old and a new ecology. Metaphysical implications from the old ecology are quite different from the new ecology, as weIl as from quantum or Newtonian physics.

Ecological communities, I argue, are objective units of nature if theyhave structure that regulates their membership. Evidence of suchstructure in contemporary ecology is scant, but the palaeoecologicalphenomenon of co-ordinated stasis is a prima facie example ofinternal regulation. I argue that no individualist attempts to explainaway the appearance of internal regulation succeeds. But no internalistmodel is fully satisfactory, either, in explaining the contrast betweenpre and post Pleistocene ecology.
