The extensive philosophical discussions and analyses in recent decades of function-talk in biology have done much to clarify what biologists mean when they ascribe functions to traits, but the basic metaphysical question—is there genuine teleology and design in the natural world, or only the appearance of this?—has persisted, as recent work both defending, and attacking, teleology from a Darwinian perspective, attest. I argue that in the context of standard contemporary evolutionary theory, this is for the most part a verbal, rather (...) than a substantive dispute: the disputants are talking past one another. To justify this claim I develop a general framework within which reductionist views, such as the standard ‘etiological’ account of biofunctions, occupy an intermediate position between what I call full-blooded realism and full-blooded anti-realism, and suggest that whether such views count as ‘realist’ views has no objective, theory-neutral answer.

This Element focuses on three challenges of evolution to religion: teleology, human origins, and the evolution of religion itself. First, religious worldviews tend to presuppose a teleological understanding of the origins of living things, but scientists mostly understand evolution as non-teleological. Second, religious and scientific accounts of human origins do not align in a straightforward sense. Third, evolutionary explanations of religion, including religious beliefs and practices, may cast doubt on their justification. We show how these tensions arise and offer potential (...) responses for religion. Individual religions can meet these challenges, if some of their metaphysical assumptions are adapted or abandoned.

As astounding as it sounds, especially to people outside of the USA (and the Middle East, and much of Africa), 13 % of US high school teachers actively advocate creationism and so-called intelligent design theory in their classrooms; another 28 % does the right thing and teaches evolution, but a whopping 60 % falls in the middle: These teachers accept evolutionary theory (though they may be fuzzy on the details), and yet do not teach it in their classrooms, in order (...) to avoid ‘‘the controversy’’ (Berkman and Plutzer 2010). It is largely at this 60 %, and to interested undergraduate and graduate students, that Kampourakis’ new book is aimed. (shrink)

I consider the broad perspectives in biology known as ‘functionalism’ and ‘structuralism’, as well as a modern version of functionalism, ‘adaptationism’. I do not take a position on which of these perspectives is preferable; my concern is with the prior question, how should they be understood? Adapting van Fraassen’s argument for treating materialism as a stance, rather than a factual belief with propositional content, in the first part of the paper I offer an argument for construing functionalism and structuralism as (...) stances also. The argument draws especially on Gould’s insights concerning functionalism and structuralism, in particular their apparent historical continuity from the pre-Darwinian period through to today. In the second part of the paper I consider Godfrey-Smith’s distinction between empirical and explanatory adaptationism, and suggest that while the former is an empirical scientific hypothesis, the latter is closely related to the functionalist stance.

In this paper I discuss a recent theory on functions called Organizational Account. This theory seeks to provide a new definition of function that overcomes the distinction between etiological and dispositional accounts and that could be used in biology as well as in technology. I present a definition of function that I think captures the intuitions of Organizational Accounts and consider several objections.

A number of areas of biology raise questions about what is of value in the natural environment and how we ought to behave towards it: conservation biology, environmental science, and ecology, to name a few. Based on my experience teaching students from these and similar majors, I argue that the field of environmental ethics has much to teach these students. They come to me with pent-up questions and a feeling that more is needed to fully engage in their subjects, and (...) I believe some exposure to environmental ethics can help focus their interests and goals. I identify three primary areas in which environmental ethics can con- tribute to their education. The first is an examination of who (or what) should be considered to be part of our moral community (i.e., the community to whom we owe direct duties). Is it humans only? Or does it include all sentient life? Or all life? Or ecosystems considered holistically? Often, readings implicitly assume one or more of these answers; the goal is to make the student more sensitive to these implicit claims and to get them to think about the different reasons that support them. The second area, related to the first, is the application of the different answers concerning the extent of the ethical community to real environmental issues and problems. Students need to be aware of how the different answers concerning the moral community can imply conflicting answers for how we should act in certain cases and to think about ways to move toward conflict resolution. The third area in which environmental ethics can contribute is a more conceptual one, focusing on central concepts such as biodiversity, sustainability, species, and ecosystems. Exploring and evaluating various meanings of these terms will make students more reflective and thoughtful citizens and biologists, sensitive to the implications that different conceptual choices make.

The dissertation criticizes two analogical applications of Darwinism to the spheres of mind and culture: the Darwinian approach to creativity and memetics. These theories rely on three basic analogies: the ontological analogy states that the basic ontological units of culture are so-called memes, which are replicators like genes; the origination analogy states that novelty in human creativity emerges in a "blind" Darwinian manner; and the explanatory units of selection analogy states that memes are "egoistic" and that they can spread independently (...) of our mind. The detailed philosophical analysis offered in the dissertation shows that these three analogies rely on either wrong or trivial statements: they provide either wrong or no new descriptions or explanations of the phenomena at hand. In Chapter One, I introduce the diverse ways, in which contemporary Darwinism is used today outside of evolutionary biology. Chapter Two explains what it means to claim that something evolves in a Darwinian manner. Chapter Three to Five address each of the three analogies separately. Darwinism applied to culture and mind, at least in the way discussed in this study, is not a dangerous idea. It leads either to wrong claims or to a re-telling in Darwinian terms of what we have already known. (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.

The eminent historian and philosopher of biology, Michael Ruse, has written several books that explore the relationship of evolutionary theory to its larger scientific and cultural setting. Among the questions he has investigated are: Is evolution progressive? What is its epistemological status? Most recently, in "Darwin and Design: Does Evolution have a Purpose?," Ruse has provided a history of the concept of teleology in biological thinking, especially in evolutionary theorizing. In his book, he moves quickly from Plato and Aristotle to (...) Kant and such British thinkers as Paley and Whewell. His main focus, though, is on Darwin's theory and its subsequent fate. Ruse rests his history on some shaky historical and philosophic assumptions, particularly the unexamined notion that evolutionary theory is an abstract entity that is unproblematically realized in different historical periods. He also assumes that Darwin conceived nature as if it were a Manchester spinning loom -- a clanking, dispassionate machine. A more subtle analysis, which Ruse eschews, might discover that Darwin's conception of nature owed a strong debt to German Romanticism and that he contrived to infuse nature with moral and aesthetic values, not to suck them from nature. Ruse proves he is a thinker to contend with, and this essay is quite contentious. (shrink)

Here we discuss the challenge posed by self-organization to the Darwinian conception of evolution. As we point out, natural selection can only be the major creative agency in evolution if all or most of the adaptive complexity manifest in living organisms is built up over many generations by the cumulative selection of naturally occurring small, random mutations or variants, i.e., additive, incremental steps over an extended period of time. Biological self-organization—witnessed classically in the folding of a protein, or in the (...) formation of the cell membrane—is a fundamentally different means of generating complexity. We agree that self-organizing systems may be fine-tuned by selection and that self-organization may be therefore considered a complementary mechanism to natural selection as a causal agency in the evolution of life. But we argue that if self-organization proves to be a common mechanism for the generation of adaptive order from the molecular to the organismic level, then this will greatly undermine the Darwinian claim that natural selection is the major creative agency in evolution. We also point out that although complex self-organizing systems are easy to create in the electronic realm of cellular automata, to date translating in silico simulations into real material structures that self-organize into complex forms from local interactions between their constituents has not proved easy. This suggests that self-organizing systems analogous to those utilized by biological systems are at least rare and may indeed represent, as pre-Darwinists believed, a unique ascending hierarchy of natural forms. Such a unique adaptive hierarchy would pose another major challenge to the current Darwinian view of evolution, as it would mean the basic forms of life are necessary features of the order of nature and that the major pathways of evolution are determined by physical law, or more specifically by the self-organizing properties of biomatter, rather than natural selection.

The Darwinian revolution supposed and imposed a much broader and more complex concept of environment than that which, until that moment, had been considered by most as part of natural history. Until Darwin, the environment of living beings had been regarded, almost exclusively, as the inanimate surroundings. This pre-Darwinian notion of environment included physicochemical and climatic variables: the living beings themselves were scarcely considered, or they were regarded just as food to be assimilated. In contrast, with Darwin, the influence of (...) living surroundings began to be regarded as having decisive importance for understanding the distribution, configuration, and viability of living beings. The relationships established among different living beings became the main and more significant features of the biological environment. This conceptual change was an exigency derived from the formulation and justification of the theory of natural selection. The idea of struggle for existence supposed by that theory requires that the biotic environment be considered critical in determining the viability of each living being. (shrink)

In The Variation of Animals and Plants under Domestication, published in 1868, Darwin used the metaphor of the architect to argue in favor of natural autonomy and to clarify the role of chance in his theory of adaptive change by variation and natural selection. In this article, I trace the history of this important heuristic instrument in Darwin's writings and letters and suggest that this metaphor was important to Darwin because it helps him to explain the role of chance, and (...) gives an argument in favor of the free will.

The problem of natural teleology in biology has traditionally focused on reconciling Aristotle’s efficient and final causation. In this paper, however, I emphasize the importance of formal causation in natural teleological explanations and suggest that undermining its legitimacy is a backdoor route to undermining natural teleology itself. Formal causation, I argue, represents the “phenotype” of an object, to use a familiar word from genetics. This means that formal causes specify not only intrinsic “genotypic” qualities of an object but also a (...) range of environments in which the object is “properly” to inhabit. Such environmental specificity is possible through conscious activity, but is not found anywhere in non-conscious nature. Das Problem der natürlichen Teleologie ist traditionellerweise darin gesehen worden, Aristoteles’ Wirkursache und seine Finalursache miteinander zu vereinbaren. Dagegen betone ich in diesem Aufsatz die Bedeutung der formalen Verursachung in natürlichen teleologischen Erklärungen. Wenn man ihre Legitimität untergräbt, so lege ich nahe, untergräbt man gleichsam durch die Hintertür natürliche Teleologie als solche. Ich argumentiere, dass formale Verursachung den „Phänotyp“ eines Objekts darstellt, um ein geläufiges Wort aus der Genetik zu verwenden. Dies bedeutet, dass formale Ursachen nicht nur intrinsische „genotypische“ Eigenschaften eines Objekts spezifizieren, sondern auch eine Bandbreite von Umgebungen, in denen das Objekt „im eigentlichen Sinn“ angesiedelt sein sollte. Diese Spezifizierung der Umgebung ist durch bewusste Aktivität möglich, findet sich aber nirgendwo in der nicht-bewussten Natur. (shrink)

The notion of biological function is fraught with difficulties—intrinsically and irremediably so, we argue. The physiological practice of functional ascription originates from a time when organisms were thought to be designed and remained largely unchanged since. In a secularized worldview, this creates a paradox which accounts of functions as selected effect attempt to resolve. This attempt, we argue, misses its target in physiology and it brings problems of its own. Instead, we propose that a better solution to the conundrum of (...) biological functions is to abandon the notion altogether, a prospect not only less daunting than it appears, but arguably the natural continuation of the naturalisation of biology.

How is moral thinking, ethics, related to evolutionary theorizing? There are two approaches, epitomized by Charles Darwin who works under the metaphor of the world as a machine, and by Herbert Spencer who works under the metaphor of the world as an organism. Although the author prefers the first approach, the aim of this paper is to give a disinterested account of both approaches.

The notion of the ‘division of physiological labour’ is today an outdated relic in the history of science. This contrasts with the fate of another notion, which was so frequently paired with the division of physiological labour, which is the concept of ‘morphological differentiation.’ This is one of the elementary modal concepts of ontogenesis. In this paper, we intend to target the problems and causes that gradually led biologists to combine these two notions during the 19th century, and to progressively (...) dissociate them, retaining only the concept of differentiation by the early 20th century. We shall adhere to the following: 1. The primitive economic concept of the division of labour is not a descriptive notion denoting a type of organisation of labour, but an etiological one: the idea of a causal relationship between this type of organization and the improvement of the whole. 2. This concept rapidly interested naturalists such as Henri Milne-Edwards, who were keen to find a rational ground for hierarchizing living forms based on anatomical complexity. 3. The validation of this notion in the realms of biology was subject to at least two conditions which were far from being fully satisfied. This did not prevent, however, the initial success of the concept of the division of physiological labour during the second half of the 19th century. 4. Finally, the gradual disqualification, within the Darwinian theoretical context, of the conception of an intrinsic hierarchical rank of organisms, led to a lack of interest in the concept of the physiological division of labour, at least in its non-Darwinian and non-ecological variant.

My book, "The Darwinian Revolution" gives an overview of the revolution as understood at the time of its writing (1979). It shows that many factors were involved, from straight science through philosophical methodology, and on to religious influences and challenges. Also of importance were social factors, not the least of which was the professionalization of science in Britain in the 19th century. Since the appearance of that book, new, significant factors have become apparent, and here I discuss some of the (...) most important -- especially the way in which evolution as an idea came into being as an epiphenomenon of the ideology of cultural progress; the (often tense) interaction between ideas of biological progress and the urge to professionalization, and of how this led to a delay in the full appreciation of what Charles Darwin had done in the "Origin;" and the ongoing divide between biological functionalists and biological formalists, a Kuhnian-type paradigm difference that persists across the Darwinian revolution.

Abstract. I respond to the criticisms of David Wisdo of my position on the relationship between science and religion. I argue that although he gives a full and fair account of my position, he fails to grasp fully my use of the metaphorical basis of modern science in my argument that, because of its mechanistic commitment, there are some questions that science not only does not answer but that science does not even attempt to answer. Hence, my position stands and (...) plays a crucial role in our understanding of the science–religion relationship. (shrink)

Evolution and Story: Beyond Neo-Darwinism and Intelligent Design This article analyses evolution from a philosophical perspective, contrasting the problems raised by both Neo-Darwinism and Intelligent Design theory. First, I discuss some of the problems that Synthetic theory presents from a scientific point of view, as well as the philosophical problems involved in the Neo-Darwinism of Dawkins, Dennett, Monod and Ruse. I argue that Neo-Darwinism, although presented as a scientific doctrine, is in fact fundamentally philosophical, and presents some important problems that (...) make it difficult to believe. On the other hand, I discuss the scope of intelligent design as a philosophical stance on the evolution of living beings, showing its problems. Finally, I propose a credible philosophical account of evolution that seeks to go beyond a scientific reading of the data of experience. (shrink)

In the biological realm, a complete explanation of a trait seems to include an explanation in terms of function. It is natural to ask of some trait, "What is its function?" or "What purpose in the organism does the particular trait serve?" or "What is the goal of its activity?" There are several views concerning the appropriate definition of function for biological matters. Two popular views of function with respect to living things are Cummins' organizational account and the Griffiths/Godfrey-Smith modern (...) history account. Whereas Cummins argues that a trait functions so as to contribute to the general organization of some organism's present structure, Griffiths, and Godfrey-Smith argue that a trait functions because of its fitness with respect to the organism's recent evolutionary history. In this paper, I show how these accounts can be made compatible and compliment one another. Given that structure, organization, operational flexibility, function, and evolutionary history are all factors to be considered in an organism's makeup, we should expect that the traits of an organism function the way they do because such traits presently contribute to the overall organization of the organism (Cummins) as well as were selected for in the organism's species' recent ancestry (Griffiths/Godfrey-Smith).

Conservation scientists are arguing whether naturalness provides a reasonable imperative for conservation. To clarify this debate and the interpretation of the term natural, I analyze three management strategies – ecosystem preservation, ecosystem restoration, and ecosystem engineering – with respect to the naturalness of their outcomes. This analysis consists in two parts. First, the ambiguous term natural is defined in a variety of ways, including (1) naturalness as that which is part of nature, (2) naturalness as a contrast to artifactuality, (3) (...) naturalness as an historical independence from human actions, and (4) naturalness as possession of certain properties. After that, I analyze the different conceptions with respect to their implications for the three management strategies. The main conclusion is that there exists no single conception of naturalness that could distinguish between the outcomes of the three management methods. Therefore, as long as the outcomes of the different methods are regarded as being of a different value in conservation, we should either abandon the idea of naturalness as the guiding concept in conservation or use the term natural only in the ways that take both its historical and feature dependent meanings into consideration.

In this work I characterize Darwinian approaches to human behavior and mind, especially evolutionary psychology, and analyze the main criticisms that these approaches have received. To this end I resort to Jean Marie Schaeffer’s criticism of the thesis of human exceptionality and the semantic perspective of scientific theories of Ronald Giere. I conclude that the main criticisms are not applicable to evolutionary psychology as a research program. I also conclude that it cannot be held a priori that the Darwinian approach (...) is not applicable to the human mind and behavior. Finally, I discuss some educational implications of these debates.

Much has been written through the years of the clash between Darwinism and natural theology, and the basic tenants of this debate are well understood (Gillispie 1959; Bowler 1977; Ruse 2003; McGrath 2011). However, the literature is still growing, and one may wonder if anything new may yet be added. Of these new literary sources, one of the richest is the online Darwin Correspondence Project, which makes it possible to search and read the full texts of all correspondence either sent (...) or received by Darwin, up to the year 1868. (This project is ongoing and letters are still being recovered and added.) The purpose of this article is to outline the role of the intelligent design argument, as espoused by its principal ..

I argue that the theological traditions of natural law and wisdom offer helpful meeting points in discussions about evolutionary “purpose” and contingency in relation to theological purpose, and serve to form the basis for a theology of nature. Natural law offers a way of describing the ordered action of God toward complexity in a contingent world without using the language of either “design” or “progress.” The theological tradition of wisdom as implicit in the natural world, learned in the human community, (...) and received as gift of grace offers a further means of interconnecting biological reality with spiritual experience, while retaining distinctions. Wisdom and natural law intersect inasmuch as natural law is participation in Eternal Wisdom, although the latter makes sense only from the prior perspective of faith. (shrink)
