The book deals with the notion of Downward Causation from a wide array of perspectives, including physics, biology, psychology, social science, communication studies, text theory, and philosophy. The book includes proponents as well as opponents discussing the validity of the notion.

Continuing his exploration of the organization of complexity and the science of design, this new edition of Herbert Simon's classic work on artificial ...

This volume provides a guide to the discussion among biologists and philosophersabout the role of concepts such as function and design in an evolutionary understanding oflife.

Many areas of science develop by discovering mechanisms and role functions. Cummins' (1975) analysis of role functions-according to which an item's role function is a capacity of that item that appears in an analytic explanation of the capacity of some containing system-captures one important sense of "function" in the biological sciences and elsewhere. Here I synthesize Cummins' account with recent work on mechanisms and causal/mechanical explanation. The synthesis produces an analysis of specifically mechanistic role functions, one that uses the characteristic (...) active, spatial, temporal, and hierarchical organization of mechanisms to add precision and content to Cummins' original suggestion. This synthesis also shows why the discovery of role functions is a scientific achievement. Discovering a role function (i) contributes to the interlevel integration of multilevel mechanisms, and (ii) provides a unique, contextual variety of causal/mechanical explanation. (shrink)

A phenomenological community is an identifiable assemblage of organisms in a local habitat patch: a local wetland or mudflat are typical examples. Such communities are typically persistent: membership and abundance stay fairly constant over time. In this paper I discuss whether phenomenological communities are functionally structured, causal systems that play a role in determining the presence and abundance of organisms in a local habitat patch. I argue they are not, if individualist models of community assembly are vindicated; i.e., if the (...) presence of one species is not typically explained by the presence or absence of specific other species. I discuss two alternatives to in- dividualism, and conclude by arguing for a dimensional model of phenomenological communities. The causal salience of a phenomenological community depends on three factors: the extent to which it is internally regulated, the extent to which it has robust boundaries, and the extent to which it has emergent properties. I conclude by using this model to frame a natural research agenda for community ecology. (shrink)

In this paper, we develop an organizational account that defines biological functions as causal relations subject to closure in living systems, interpreted as the most typical example of organizationally closed and differentiated self-maintaining systems. We argue that this account adequately grounds the teleological and normative dimensions of functions in the current organization of a system, insofar as it provides an explanation for the existence of the function bearer and, at the same time, identifies in a non-arbitrary way the norms that (...) functions are supposed to obey. Accordingly, we suggest that the organizational account combines the etiological and dispositional perspectives in an integrated theoretical framework.

Neo-teleology is the two part thesis that, e.g., (i) we have hearts because of what hearts are for: Hearts are for blood circulation, not the production of a pulse, so hearts are there--animals have them--because their function is to circulate the blood, and (ii) that (i) is explained by natural selection: traits spread through populations because of their functions. This paper attacks this popular doctrine. The presence of a biological trait or structure is not explained by appeal to its function. (...) To suppose otherwise is to trivialize natural selection.

An analysis of two heuristic strategies for the development of mechanistic models, illustrated with historical examples from the life sciences. In Discovering Complexity, William Bechtel and Robert Richardson examine two heuristics that guided the development of mechanistic models in the life sciences: decomposition and localization. Drawing on historical cases from disciplines including cell biology, cognitive neuroscience, and genetics, they identify a number of "choice points" that life scientists confront in developing mechanistic explanations and show how different choices result in divergent (...) explanatory models. Describing decomposition as the attempt to differentiate functional and structural components of a system and localization as the assignment of responsibility for specific functions to specific structures, Bechtel and Richardson examine the usefulness of these heuristics as well as their fallibility—the sometimes false assumption underlying them that nature is significantly decomposable and hierarchically organized. When Discovering Complexity was originally published in 1993, few philosophers of science perceived the centrality of seeking mechanisms to explain phenomena in biology, relying instead on the model of nomological explanation advanced by the logical positivists (a model Bechtel and Richardson found to be utterly inapplicable to the examples from the life sciences in their study). Since then, mechanism and mechanistic explanation have become widely discussed. In a substantive new introduction to this MIT Press edition of their book, Bechtel and Richardson examine both philosophical and scientific developments in research on mechanistic models since 1993.

What Is Biodiversity? is a theoretical and conceptual exploration of the biological world and how diversity is valued. Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny (...) also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. (shrink)

The organizational account of biological functions interprets functions as contributions of a trait to the maintenance of the organization that, in turn, maintains the trait. As has been recently argued, however, the account seems unable to provide a unified grounding for both intra- and cross-generation functions, since the latter do not contribute to the maintenance of the same organization which produces them. To face this ‘ontological problem’, a splitting account has been proposed, according to which the two kinds of functions (...) require distinct organizational definitions. In this article, we propose a solution for the ontological problem, by arguing that intra- and cross-generation functions can be said to contribute in the same way to the maintenance of the biological organization, characterized in terms of organizational self-maintenance. As a consequence, we suggest maintaining a unified organizational account of biological functions. (shrink)

Function and teleology can be naturalized either by reference to systems with a particular type of organization or by reference to a particular kind of history. As functions are generally ascribed to states or traits according to their current role and regardless of their origin, etiological accounts are inappropriate. Here, I offer a systems-theoretical interpretation as a new version of an organizational account of functionality, which is more comprehensive than traditional cybernetic views and provides explicit criteria for empirically testable function (...) ascriptions. I propose, that functional states, traits or items are those components of a complex system, which are under certain circumstances necessary for their self-re-production. I show, how this notion can be applied in intra- and trans-generational function ascriptions in biology, how it can deal with the problems of multifunctionality and functional equivalents, and how it relates to concepts like fitness and adaptation. Finally, I argue that most intentional explanations can be treated as functional explanations. (shrink)

This collection of specially commissioned essays puts top scholars head to head to debate the central issues in the lively and fast growing field of philosophy ...

This paper reviews the debate on the notion of biological function and on functional explanation as this takes place in philosophy. It describes the different perspectives, issues, intuitions, theories and arguments that have emerged. The author shows that the debate has been too heavily influenced by the concerns of a naturalistic philosophy of mind and argues that in order to improve our understanding of biology the attention should be shifted from the study of intuitions to the study of the actual (...) practice of biological inquiry.

The idea of a higher level phenomenon having a downward causal influence on a lower level process or entity has taken a variety of forms. In order to discuss the relation between emergence and downward causation, the specific variety of the thesis of downward causation (DC) must be identified. Based on some ontological theses about inter-level relations, types of causation and the possibility of reduction, three versions of DC are distinguished. Of these, the `Strong' form of DC is held to (...) be in conflict with contemporary science; the `Medium' version of DC may for instance describe thoughts constraining neurophysiological states, while the `Weak' form of DC is physically acceptable but may not in practice be a feasible description of the mind/brain or the cell/molecule relation. All forms have their specific problems, but the Medium and the Weak version seems to be most promising. (shrink)

But what are functions? Here, 15 leading scholars of philosophy of psychology and philosophy of biology present new essays on functions.

Sugar, pork, beer, corn, cider, scrapple, and hoppin' John all became staples in the diet of colonial America. The ways Americans cultivated and prepared food and the values they attributed to it played an important role in shaping the identity of the newborn nation. In A Revolution in Eating, James E. McWilliams presents a colorful and spirited tour of culinary attitudes, tastes, and techniques throughout colonial America. Confronted by strange new animals, plants, and landscapes, settlers in the colonies and West (...) Indies found new ways to produce food. Integrating their British and European tastes with the demands and bounty of the rugged American environment, early Americans developed a range of regional cuisines. From the kitchen tables of typical Puritan families to Iroquois longhouses in the backcountry and slave kitchens on southern plantations, McWilliams portrays the grand variety and inventiveness that characterized colonial cuisine. As colonial America grew, so did its palate, as interactions among European settlers, Native Americans, and African slaves created new dishes and attitudes about food. McWilliams considers how Indian corn, once thought by the colonists as "fit for swine," became a fixture in the colonial diet. He also examines the ways in which African slaves influenced West Indian and American southern cuisine. While a mania for all things British was a unifying feature of eighteenth-century cuisine, the colonies discovered a national beverage in domestically brewed beer, which came to symbolize solidarity and loyalty to the patriotic cause in the Revolutionary era. The beer and alcohol industry also instigated unprecedented trade among the colonies and further integrated colonial habits and tastes. Victory in the American Revolution initiated a "culinary declaration of independence," prompting the antimonarchical habits of simplicity, frugality, and frontier ruggedness to define American cuisine. McWilliams demonstrates that this was a shift not so much in new ingredients or cooking methods, as in the way Americans imbued food and cuisine with values that continue to shape American attitudes to this day.

Neste artigo, discutimos o papel das explicações teleológicas na teoriaGaia. Mostramos que seu principal proponente, James Lovelock, pretendeevitá-las devido a uma interpretação equivocada da natureza de taisexplicações. Na tentativa de evitar compromissos com a teleologia,Lovelock recorre ao conceito de propriedades emergentes. Esta não é,contudo, uma saída consistente, porque os conceitos de propriedadesemergentes e teleologia não são mutuamente excludentes. Discutimostambém as dificuldades de uma interpretação de Gaia de uma perspectivateleonômica, considerando problemas como o da noção de superorganismo.Para avaliar o estatuto das (...) explicações teleológicas em Gaia, examinamoso caso da interação entre algas e nuvens, que resultou num novo campo depesquisas e expõe as contribuições teóricas e empíricas que Gaia podeoferecer. Com base nos argumentos apresentados ao longo do artigo,sugerimos uma reorganização da estrutura do programa de pesquisa Gaia,visando à continuação de seu progresso teórico e empírico.In this paper, we discuss the role of teleological explanations in Gaia theory.We show that its main proponent, James Lovelock, intends to avoid themdue to a misinterpretation of the nature of teleological explanations. Inorder to avoid a commitment to teleology, Lovelock appeals to the conceptof emergent properties. This is not a consistent solution, however, since the concepts of emergent properties and teleology are not mutuallyexclusive. We also discuss difficulties in an interpretation of Gaia from ateleonomic perspective, discussing problems such as that of the notion ofsuperorganism. In order to appraise the status of teleological explanationsin Gaia, we examine the case of the interaction between algae and clouds,which gave birth to a new research field and show the theoretical andempirical contributions that Gaia can bring. Based on the argumentsdeveloped in the paper, we suggest a reorganization of the structure ofGaia research program, in order to go on with its theoretical and empiricalprogress. (shrink)

The main cognitive target of Ecology is the functional analysis of the ecological processes and systems. It does not suppose, meanwhile, that these processes and systems are designed systems and processes like individual leaving beings. The Ecology, likewise Physiology, is constitutively guided by the presupposition of a privileged state , to be explained, that it is the persistence of the systems and processes that she studied; and its functional analyses obey to this presupposition. Ecology supposes an ideal of natural order (...) , under which consideration this privileged state is thinking as an improbable state of things and, for that, needed of explanation; and, in what concerns this latter point, the analogy between Ecology and Physiology can also result instructive.

Biological functions are dispositions or effects a trait has which explain the recent maintenance of the trait under natural selection. This is the "modern history" approach to functions. The approach is historical because to ascribe a function is to make a claim about the past, but the relevant past is the recent past; modern history rather than ancient.

O discurso funcional é tanto ubíquo quanto central na ecologia contemporânea, principalmente no contexto das pesquisas sobre biodiversidade e funcionamento ecossistêmico, que emergiram nos anos 1990 em meio à crise da biodiversidade. Entretanto, a despeito dessa forte presença na ecologia, o discurso funcional ainda não tem sido investigado de maneira adequada nesta ciência, na medida em que muitos problemas fundamentais a respeito do tema ainda permanecem sem respostas claras. Por um lado, os ecólogos que lançam mão de explicações funcionais parecem (...) simplesmente tomar como dado ou autoevidente o conceito de função. Contudo, ele nada tem de trivial, tendo em vista os problemas filosóficos suscitados pela linguagem funcional ou teleológica nas explicações biológicas, pelo menos desde Aristóteles. Por outro lado, poucos filósofos da ciência têm se mostrado especialmente interessados nos problemas epistemológicos associados ao discurso funcional em ecologia. Tomando essa situação como ponto de partida, nossa abordagem neste artigo se dá em três etapas. Inicialmente, procedemos a uma análise conceitual de função na ecologia atual, com ênfase nos estudos que relacionam a biodiversidade às propriedades ecossistêmicas. Esboçamos três significados principais do conceito, mostrando os pressupostos e as implicações associados a cada um deles. Num segundo momento, procedemos a uma análise das razões que levam a suspeitas ou objeções contra a linguagem funcional na ecologia. Por fim, num terceiro momento, lançamos algumas sugestões sobre como fundamentar ou dar mais clareza ao discurso funcional na ecologia contemporânea. (shrink)

Ecology is an historical science in which theories can be as difficult to test as they are to devise. This volume, intended for ecologists and evolutionary biologists, reviews ecological theories, and how they are generated, evaluated, and categorized. Synthesizing a vast and sometimes labyrinthine literature, this book is a useful entry into the scientific philosophy of ecology and natural history. The need for integration of the contributions to theory made by different disciplines is a central theme of this book. The (...) authors demonstrate that only through such integration will advances in ecological theory be possible. Ecologists, evolutionary biologists, and other serious students of natural history will want this book. (shrink)

Research in modern biology has largely been developed according to two main ways of inquiry, as they were outlined by Charles Darwin and Claude Bernard. Each stands for a specific approach to the living corresponding to two different methodological rules: the principle of natural selection and the principle of causation.
