This paper examines the neo-Aristotelian account of species natures as ‘life-forms’, which we owe to Philippa Foot, Michael Thompson and their defenders. I begin by developing two problems for their view: a problem of underdetermination and a problem generated by psychological work on ‘folk essentialism’. I move on to consider their important transcendental argument, which suggests that claims about life-forms are presupposed by all efforts to describe the organic world. In response, I sketch a neo-Kantian projectivist position, which agrees (...) that life-forms are presupposed in these contexts, while denying that such life-forms are real. This position makes a better sense of the phenomena cited in support of the neo-Aristotelian view, while avoiding the problems raised for that view in the first half of this paper. (shrink)

What are biological species? Aristotelians and Lockeans agree that they are natural kinds; but, evolutionary theory shows that neither traditional philosophical approach is truly adequate. Recently, Michael Ghiselin and David Hull have argued that species are individuals. This claim is shown to be against the spirit of much modern biology. It is concluded that species are natural kinds of a sort, and that any 'objectivity' they possess comes from their being at the focus of a consilience of (...) inductions. (shrink)

Ki Jeong-jin proposed a distinctive perspective in which the unified li 理 transforms into individual li by itself, and these individual li subsequently become the natures of distinct species. This viewpoint starkly contrasts with the Yulgok school’s theory, which posits that the unified principle differentiates through qi 氣. In response, Jeon Woo critiqued Ki Jeong-jin by adhering to the doctrines of the Yulgok school. According to him, a species’ nature is wholly attributed to the influence of qi. (...) Ki Jeong-jin’s disciple, Jeong Eui-rim, defended his teacher’s doctrine by embracing the organic model. He likened the relationship between Heaven and all things to that of the body and its limbs, contending that it embodies a ‘whole-part’ connection. Just as the parts coalesce to constitute the whole, the whole is omnipresent within the parts; similarly all things come together to form Heaven, and Heaven is omnipresent within all things. Based on this, Jeong Eui-rim concluded that all things ‘originally existed’ alongside Heaven, and further postulated that the li of all things originated from this ‘original existence.’ Consequently, his contention is not that the unified li differentiates into the li of all things through qi but that the li of all things inherently existed and evolved into the natures of various species.

In _Realism and Naturalizing Knowledge_ (Keisho Shobo, 2013), Ryo Uehara carefully formulates the homeostatic property cluster theory of natural kinds and expands it by applying this framework to artifacts and knowledge and thereby drawing them in the naturalistic picture of the world. This is a substantial addition to the development of naturalistic philosophy in Japan. In this essay I shall make general comments on his account of natural kinds in the following respects: Uehara's distinction between real and nominal kinds, his (...) objection to the species-as-individual thesis, the relative lack of attention to the distinction between the realism of natural kinds and the scientific realism, and finally, races as possible natural kinds.

If ecological systems are functionally organised, they can possess functions or malfunctions. Natural function would provide justification for conservationists to act for the protection of current ecological arrangements and control the presence of populations that create ecosystem malfunctions. Invasive species are often thought to be malfunctional for ecosystems, so functional arrangement would provide an objective reason for their control. Unfortunately for this prospect, I argue no theory of function, which can support such normative conclusions, can be applied to large (...) scale ecosystems. Instead ecological systems have causal structure, with small clusters of populations achieving functional arrangement. This, however, does not leave us without reason to control invasive species. We can look at the causal arrangement of ecological systems for populations that support ecological features that we should preserve. Populations that play a causal role in reducing biodiversity should be controlled, because biodiversity is a good all prudent agents should want to preserve. (shrink)

Lucia Schwarz urges a reconsideration of the implications of species egalitarianism, which is an essential element of the position in environmental ethics that Paul Taylor calls “respect for nature.” Species egalitarianism’s claim that every living thing has equal inherent worth appears to lead to counterintuitive conclusions, such as that killing a human being is no worse than killing a dandelion. Species egalitarians have generally responded by explaining that species egalitarianism is compatible with recognizing moral differences (...) between killing different types of living things, and that some killing is morally permissible. Schwarz raises doubts about whether this deflationary defensive strategy is philosophically justified, and suggests that taking seriously the supposedly repugnant implications of species egalitarianism may have a salutary effect on the overall debate.

ORIGIN OF SPECIES. INTRODUCTION. When on board HMS 'Beagle,' as naturalist, I was ranch struck with certain facts in the distribution of the organic beings ...

Concepts and methods originating in one discipline can distort the structure of another when they are applied to the latter. I exemplify this mostly with reference to systematic biology, especially problems which have arisen in relation to the nature of species. Thus the received views of classes, individuals (which term I suggest be replaced by units to avoid misunderstandings), and sets are all inapplicable, but each can be suitably modified. The concept of fuzzy set was developed to deal (...) with species and I defend its applicability. Taxa at all levels are real and participate in biological processes. Analysis of cause and pattern provides the deep structure in which metabiology is grounded; violation of this principle has led to diverse errors in biology. (shrink)

The nature of science is a primary goal in school science. Most teachers are not well-prepared for teaching NOS, but a sophisticated and in-depth understanding of NOS is necessary for effective teaching. Some authors emphasize the need for teaching NOS in context. Species, a central concept in biology, is proposed in this article as a concrete example of a means for achieving increased understanding of NOS. Although species are commonly presented in textbooks as fixed entities with a (...) single definition, the concept of species is a highly discussed one in the science and the philosophy of biology. A multitude of species concepts exist, reflecting both the views and interests of researchers and their utility in different organism groups. The present study serves to address the following questions: How do textbooks in Norwegian primary and lower secondary schools present the concept of species? Can inquiries into the concept of “species” serve to highlight aspects of NOS? A review of the available literature on species and species concepts in school is also performed. In the schoolbooks, the biological species concept is commonly used as the main definition, whereas the morphological species concept is represented by additional remarks of similarity. The potential and pitfalls of using the species concept for teaching NOS are discussed, with NOS being discussed both as a family resemblance concept and as a consensus list. Teacher education is proposed as a starting point for inducing a more sophisticated view of biology into schools. (shrink)

Although it is possible to regard a species as a set with a special internal structure, it is preferable to regard a species as an individual precisely to emphasize this internal structure. It is necessary to recognize, moreover, that two organisms that are part of a single entity with respect to one process need not be part of a single entity with respect to another process. Furthermore, choosing to regard two entities (with respect to one process) as conspecific (...) is not to deny that there are two entities within this species. Thus, the systematist need not propose formal names for every entity he discovers, but the names he proposes ought to be as faithful to the relationship among the entities as is possible. (shrink)

In this article, I argue that species are mutable in Hegel’s philosophy of biology. While scholars have argued for the compatibility of Hegel’s philosophy and Darwin’s theory of evolution, none have dealt with the ontological status of species in their respective accounts. In order to make the case that for Hegel species are mutable, I first deal with a textual problem that in the 1827 edition of the Encyclopedia, the species concept appears after the sexual relationship, (...) whereas in the 1830 edition it appears prior. I argue that these different sequences entail different models for the species concept. By examining the conceptual development leading up to the account of species, on the one hand, and contemporary biological accounts of the status of species on the other, I argue that the 1827 model is more consistent both with Hegel’s method and with the species concept of contemporary biology.

Conservation biologists and other environmentalists confront five obstacles in building support for regulatory policies that seek to exclude or remove introduced plants and other non-native species that threaten to harm natural areas or the natural environment. First, the concept of “harm to the natural environment” is nebulous and undefined. Second, ecologists cannot predict how introduced species will behave in natural ecosystems. If biologists cannot define “harm” or predict the behavior of introduced species, they must target all non-native (...) species as potentially “harmful”. an impossibly large regulatory task. Third, loss of species richness may constitute harm to an environment, but introduced organisms typically, generally, and significantly add to species richness in ecosystems. If species richness correlates with desirable ecosystem properties, moreover, such as stability and productivity, as some ecologists believe, then introduced organisms, by increasing species richness, would support those desirable properties. Fourth, one may plausibly argue that extinction constitutes environmental harm, but there is no evidence that non-native species, especially plants, are significant causes of extinction, except for predators in certain lakes and other small island-like environments. Fifth, while aesthetic, ethical, and spiritual values may provide a legitimate basis for invasive species policy, biologists often cite concepts such as “biodiversity” and ecosystem “health” or “integrity” to provide a scientific justification. To assert that non-native species threaten biodiversity or undermine ecosystem health, however, may be to draw conceptual entailments or consequences from definitions of “biodiversity” and “integrity” that arbitrarily exclude non-native species or make the presence of exotic species a per se indicator of decline.

Charles Darwin's On the Origin of Species is unquestionably one of the chief landmarks in biology. The Origin (as it is widely known) was literally only an abstract of the manuscript Darwin had originally intended to complete and publish as the formal presentation of his views on evolution. Compared with the Origin, his original long manuscript work on Natural Selection, which is presented here and made available for the first time in printed form, has more abundant examples and illustrations (...) of Darwin's argument, plus an extensive citation of sources.

Familiarity with Charles Darwin's treatise on evolution is essential to every well-educated individual. One of the most important books ever published--and a continuing source of controversy, a century and a half later--this classic of science is reproduced in a facsimile of the critically acclaimed first edition.

Sagoff [Journal of Agricultural and Environmental Ethics 18 (2005), 215–236] argues, against growing empirical evidence, that major environmental impacts of non-native species are unproven. However, many such impacts, including extinctions of both island and continental species, have both been demonstrated and judged by the public to be harmful. Although more public attention has been focused on non-native animals than non-native plants, the latter more often cause ecosystem-wide impacts. Increased regulation of introduction of non-native species is, therefore, warranted, (...) and, contra Sagoff’s assertions, invasion biologists have recently developed methods that greatly aid prediction of which introduced species will harm the environment and thus enable more efficient regulation. The fact that introduced species may increase local biodiversity in certain instances has not been shown to result in desired changes in ecosystem function. In other locales, they decrease biodiversity, as they do globally. (shrink)

Present-day thought on the notion of species is troubled by a mistaken understanding of the nature of the issue: while the species problem is commonly understood as concerning the epistemology and ontology of one single scientific concept, I argue that in fact there are multiple distinct concepts at stake. An approach to the species problem is presented that interprets the term ‘species’ as the placeholder for four distinct scientific concepts, each having its own role in (...) biological theory, and an explanation is given of the concepts involved. To illustrate how these concepts are commonly conflated, two widely accepted ideas on species are criticized: species individualism and species pluralism. I argue that by failing to distinguish between the four concepts and their particular roles in contemporary biological theory, these ideas stand in the way of a final resolution of the species problem.

This paper argues that typical biological species are natural kinds, on a familiar realist understanding of natural kinds—classes of individuals across which certain properties cluster together, in virtue of the causal workings of the world. But the clustering is far from exceptionless. Virtually no properties, or property-combinations, characterize every last member of a typical species—unless they can also appear outside the species. This motivates some to hold that what ties together the members of a species is (...) the ability to interbreed, others that it is common descent. Yet others hold that species are scattered individuals,of which organisms are parts rather than members. But not one of these views absolves us of the need to posit a typical phenotypic profile. Vagueness is here to stay. Some seek to explain the vagueness by saying species are united by “homeostatic property clusters”; but this view collapses into the more familiar realist picture. (shrink)

The fact that the names of biological species refer independently of identifying descriptions does not support the view of Ghiselin and Hull that species are individuals. Species may be regarded as natural kinds whose members share an essence which distinguishes them from the members of other species and accounts for the fact that they are reproductively isolated from the members of other species. Because evolutionary theory requires that species be spatiotemporally localized their names cannot (...) occur in scientific laws. If natural kind status is denied to species on this ground, it must also be denied to most classes of concrete entities which are now accorded such status. (shrink)

This essay reviews one of the most recent books in a trend of new publications proffering evolutionary theorising about aesthetics and the arts—themes within an increasing literature on aspects of human life and human nature in terms of evolutionary theory. Stephen Davies’ The Artful Species links some of our aesthetic sensibilities with our evolved human nature and critically surveys the interdisciplinary debate regarding the evolutionary status of the arts. Davies’ engaging and accessible writing succeeds in demonstrating the (...) maturity and scope of the field and his critique is timely and unparalleled. A laudable effort, however it may have benefited from espousing a co-evolutionary model more explicitly. Moreover there may be reason to question the usefulness of the standard set of distinctions (‘adaptation’, ‘spandrel’, ‘technology’) that Davies appeals to. (shrink)

This paper seeks to exhibit and explain, by way of comparison, two ideal kinds of knowledge: knowledge based on classifications according to genera and species, as in Aristotelianism and common sense, and scientific knowledge based on the application of laws of nature. I will proceed by attempting (1) to determine the role that presuppositions play in knowledge in general by means of the distinction between content and form; (2) to describe and explain the main features of both ideal (...) forms of knowledge; and, finally, (3) to analyze the relation between these two forms of knowledge as it is presented in Eddington's celebrated discussion of the “two tables”. I will be critical of the widespread view that modern science is the correct form of knowledge, and that common sense is merely an illusion. (shrink)

This paper explores the idea of 'respect for nature' in the Earth Charter. It maintains that the Earth Charter proposes a broadly holistic environmental ethic where, in situations of conflict, species are given ethical priority over the lives of individual sentient organisms. The paper considers policy implications of this perspective, looking by means of example at the current European environmental policy dispute about the ruddy and white-headed duck. Questions about the value of species and biological diversity this (...) raises are explored. The paper concludes that the principle of valuing individual animal lives should be given more prominence in Earth Charter principles. (shrink)

This essay examines the relationship between Marti Kheel’s ecofeminism, particularly as articulated in her recent book Nature Ethics, and holistic eco-philosophy. It begins by arguing that while Kheel’s view shares some common ground with holistic thinkers, her position is best understood as one that re-conceives the meaning of holism. Next, her comments on species preservation are discussed both to show her individualism, and to highlight a weakness in her approach to issues involving at-risk species. It is then (...) suggested that one could develop a more holistic answer to questions about species that is consonant with Kheel’s overall philosophical approach. (shrink)

This chapter defends a pluralist understanding of species on which a normative species concept is viable and can support natural goodness evaluations. The central question here is thus: Since organisms are to be evaluated as members of their species, how does a proper understanding of species affect the feasibility of natural goodness evaluations? Philippa Foot has argued for a form of natural goodness evaluation in which living things are evaluated by how well fitted they are for (...) flourishing as members of their species, in ways characteristic of their species. She has further argued that assessments of moral goodness in humans are of the same evaluative form. However, natural goodness evaluations and, by extension, the natural goodness approach, do not garner justification in virtue of employing a scientifically privileged conception of species. The natural goodness approach is only justified given particular metaethical and normative commitments that are independent of naturalism, since the approach does not depend upon naturalism alone.

In hybrid nature that results from a random mix of technological infrastructures and natural ecosystems, environmental fundamentals are modified producing dramatic effects on the semiosis of several species. Human intrusion in ecosystems creates new spatial configurations that have a reduced ecological complexity when compared with systems less affected by human manipulation. This causes cascading effects on other environmental fundamentals. F.i., systems that face a low complexity, are more exposed to changes that in turn can reduce the performances of (...) individual species due to a higher level of uncertainty. The flux of information could be apparently maintained in hybrid nature when some natural patterns and processes are replaced by human artifacts and associated dynamics, but the process of signification could be strongly modified. The strict contact between people and wild organisms in hybrid nature requires new types of strategies to guarantee the continuation of the natural dynamic of populations and communities. Rural sanctuaries are proposed as one of the possible models on which to invest in order to harmonize the technological and natural processes with the goal to assure a multiscale sustainability.

Examines Darwin’s concept of species in a philosophical context.

This collection of original essays--by philosophers of biology, biologists, and cognitive scientists--provides a wide range of perspectives on species. Including contributions from David Hull, John Dupre, David Nanney, Kevin de Queiroz, and Kim Sterelny, amongst others, this book has become especially well-known for the three essays it contains on the homeostatic property cluster view of natural kinds, papers by Richard Boyd, Paul Griffiths, and Robert A. Wilson.

My aims in this article are threefold. First, I evaluate attempts to drive a wedge between the human and the natural in order to show that destroyed natural environments and extinct species cannot be restored; next, I examine the analogy between aesthetic value and the value of natural environments; and finally, I suggest briefly a different set of analogies with such human associations as families and cultures. My tentative conclusion is that while the recreation of extinct species may (...) be logically impossible, the restoration of natural environments raises only (formidable, no doubt) technical difficulties. Opponents of destructive developments which do not exterminate species, therefore, had better look elsewhere, rather than relying on the claim that restoration is logically impossible. (shrink)

Biological type specimens are a particular kind of voucher specimen stored in natural history collections. Their special status and practical use are discussed in relation to the description and naming of taxonomic zoological diversity. Our current system, known as Linnaean nomenclature, is governed by the International Code of Zoological Nomenclature. The name of a species is fixed by its name-bearing type specimen, linking the scientific name of a species to the type specimen first designated for that species. (...) The name-bearing type specimen is not necessarily a typical example of the species, while establishment of the boundaries of a species requires empirical taxonomic studies. The International Code of Zoological Nomenclature allows for the naming of new species in the absence of preserved specimens. However, photos and DNA sequences should not function as primary type material, while new species should not be described and named without deposition of at least one type specimen in a collection. Philosophically, species are individuals, spatiotemporally restricted entities. Therefore, Linnaean species names are proper names, which do not define the taxon but serve as a label, providing an ostensive definition of a species. Paratypes have no name-bearing function but, nevertheless, are highly valued specimens in natural history collections. Paratypes should be restricted to those specimens originating from the same sample as the holotype. Diagnosis of a species taxon involves establishment of a connection between a Linnaean name and determination of the boundaries of the species. A first step in this process is the choice of an appropriate species concept. It is not the examination of holotypes and paratypes that necessarily provides the best estimate of the taxonomic boundaries of a species, but this is facilitated by a set of voucher specimens known as the hypodigm. Dissatisfaction with the present nomenclatural code led some researchers to propose emendations. Other taxonomists suggested abandoning Linnaean nomenclature and proposed the alternative PhyloCode, albeit that it relegates the naming of species taxa to the traditional nomenclatural codes.

Edited from the author's posthumous works by Agnes von Cranach. Topics incl. natural science & idealistic philosophy, general attempts to define life, vitalism, mechanism, etc.\Here Am I Where Are You?: The Behavior of the Greylag Goose was thought to be Konrad Lorenz's last book. However, in 1991 the "Russian Manuscript" was discovered in an attic, and its subsequent publication in German has become a scientific sensation. Written under the most extreme conditions in Soviet prison camps, the "Russian Manuscript" was the (...) first outline of a large-scale work on behavioral science. This translation contains a synopsis of all the ideas that made Lorenz famous as the founder of ethology, the study of comparative animal behavior. Written just after World War II, while the author was incarcerated in a Soviet prison camp, this so-called "Russian manuscript" was believed lost forever. Its rediscovery in 1991 and, now, its publication represent a major contribution to the history of science and the advancement of the behavioral sciences. This book contains some of the earliest formulations of the discipline that Lorenz called comparative behavioral research (i.e., ethology); its theories also portend the development of sociobiology and the new fields of behavioral and genetic psychology. He writes, "The route to an understanding of humans leads just as surely through an understanding of animals as the evolutionary pathway of humans had led through animal precursors." Lorenz also devotes almost equal attention to the "Philosophical Prolegomena" as to the "Biological Prologomena," arguing, in the process, for a synthesis between the sciences and the humanities as complementary expressions of human cognition. The text, edited by Lorenz's daughter, is full of literary excesses; although comprehensible to the lay reader, it is not particularly enjoyable to read. Still, such a book's value cannot be measured by its popularity alone.

The idea of naturalizing metaphysics stretches back to Locke and Newton. Recently it has been revived by Ross and Ladyman et al (2007) in ‘Every Thing Must Go’. At the heart of the doctrine is the idea that metaphysics should be constrained by actual science (science which is current and institutionally valid). It is my attempt in this paper to naturalize the metaphysics of the species problem by proposing a species concept which conforms to the principles set out (...) in Ross and Ladyman et al's book. This is a concept which conforms strictly with current work in the field of evolutionary theory, with specific reference to theories in Information theory and Thermodynamics. In the end I use as an example of non-naturalized metaphysics Matthew Slater's paper ‘The Indeterminacy Problem for Species as Individuals’. (shrink)

In The Origin of Species (1859) Darwin challenged many of the most deeply-held beliefs of the Western world. Arguing for a material, not divine, origin of species, he showed that new species are achieved by "natural selection."

As well as a stimulating introduction and detailed notes, this edition offers a register (...) of the many writers referred to by Darwin in the text. (shrink)

: Whether or not extinction caused by human activities is natural depends on which sense of the term 'natural' is under consideration. Given one sense of that term which has some grip on the popular imagination, it is. This suggests that at a minimum environmentalists should be very careful about invoking 'the natural' and related concepts such as 'acting naturally' when they propose moral principles. I argue here for the stronger claim that the 'natural' is either redundant and serves to (...) obscure more than it brings to light, or that it is bound up with a picture of the world which is false, and so theoretically useless. Thus 'the natural' can do no useful theoretical work in a completely developed environmental ethic. (shrink)
