The paper offers an argument against Kripke’s assertion, that it is valid for all names of natural species, that they have no connotations. The argumentation has is roots in the semantic conception of S. Kripke as articulated in his Naming and necessity. i.e., it is an „argument from inside“ the conception itself. The argument consists of two parts: setting the conditions under which the name of a natural species has a connotation; constructing a situation, in which (...) these conditions are fulfilled.

Jean-Baptiste Lamarck was a prolific writer, a multifaceted naturalist, and a zoologist by second profession. Throughout his adult life he lived up to his passion of politely contributing to the advancement of natural philosophy by publishing more than 30,000 pages, probably too much for even the most scrupulous historians of science who seek to reconstruct his theories and to shed some light on the role he played in late eighteenth-century and early nineteenth-century biology.

The aim of this paper is to analyse Alexander von Humboldt's views on the theory of evolution and tackle the following question: Can Humboldt be considered an evolutionist? I seek to show that Humboldt acknowledges three essential Darwinian elements of the theory of evolution: fossil records, the geographical distribution of species and the struggle for survival. Further, Humboldt recognises a special relation between the natural environment and organic life, and understands it in light of his naturalistic holism. This (...) holism reveals the unity of organic and inorganic nature and highlights the agency of organic life whilst allowing it to create and preserve the adaptive conditions in the natural environment. Accordingly, I argue that Humboldt believes some kind of evolutionary process happens in nature. However, due to the immense influence of Kant’s transcendental study and the rigid utilisation of the empirical method, Humboldt concludes that we cannot acquire knowledge of the exact course of the evolutionary process. This, however, does not imply Humboldt discredits the theory of evolution. (shrink)

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.

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)

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.

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)

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)

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)

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.

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.

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 _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.

Perhaps the most readable and accessible of the great works of scientific imagination, The Origin of Species sold out on the day it was published in 1859. Theologians quickly labeled Charles Darwin the most dangerous man in England, and, as the Saturday Review noted, the uproar over the book quickly "passed beyond the bounds of the study and lecture-room into the drawing-room and the public street." Yet, after reading it, Darwin's friend and colleague T. H. Huxley had a different (...) reaction: "How extremely stupid not to have thought of that." Based largely on Darwin's experience as a naturalist while on a five-year voyage aboard H.M.S. Beagle, The Origin of Species set forth a theory of evolution and natural selection that challenged contemporary beliefs about divine providence and the immutability of species. A landmark contribution to philosophical and scientific thought, this edition also includes an introductory historical sketch and a glossary Darwin later added to the original text. Charles Darwin grew up considered, by his own account, "a very ordinary boy, rather below the common standard of intellect." A quirk of fate kept him from the career his father had deemed appropriate--that of a country parson--when a botanist recommended Darwin for an appointment as a naturalist aboard H.M.S. Beagle from 1831 to 1836. Darwin is also the author of the five-volume work Zoology of the Voyage of the Beagle (1839) and The Descent of Man (1871). (shrink)

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 (...) class='Hi'>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.

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)

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.

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)

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)

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.

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.

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.

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)

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

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.

Species in biology are traditionally perceived as kinds of organisms about which explanatory and predictive generalizations can be made, and biologists commonly use species in this manner. This perception of species is, however, in stark contrast with the currently accepted view that species are not kinds or classes at all, but individuals. In this paper I investigate the conditions under which the two views of species might be held simultaneously. Specifically, I ask whether upon acceptance (...) of an ontology of species as diachronic segments of the tree of life species can perform the epistemic role of kinds of organisms to which explanatory and predictive generalizations apply. I show that, for species-level segments of the tree of life, several requirements have to be met before the performance of this epistemic role is possible, and I argue that these requirements can be met by defining species according to the Composite Species Concept proposed by Kornet and McAllister in the 1990s.

This body of work is motivated by an apparent contradiction between, on the one hand, Darwin’s testimony in his autobiographical text about a supposed perceptual colour blindness before the aesthetic magnificence of natural landscapes, and, on the other hand, the last paragraph of On the Origin of Species, where he claims to perceive the forms of nature as beautiful and wonderful. My aim is to delve into the essence of the Darwinian perception of beauty in the context of (...) the Weberian concept of “disenchantment of the world”, assumed as a possible conceptual axis that enables the unravelling of the core of this contrast of perceptions. In acknowledging the theory of evolution as one of the most prominent scientific theories likely to have contributed to disenchantment, a number of questions arise: Is disenchantment compatible with aesthetic experience and sensibility before natural beauty? Was it Darwin’s disenchanted conception of the world that led him to believe he was colour blind? To answer these questions, a computer-assisted semantic analysis of lexical frequency and variability, most especially focused on aesthetic-emotional and religious or spiritual adverbs and adjectives, has been undertaken across the six editions of The Origin. The semantic analysis demonstrates that, although disenchanted, Darwin’s descriptions of, mainly, the adaptational excellence of living beings, reflect an aesthetically enriched perception of nature. It is concluded that Darwin’s perceptual colour blindness, then, might be based on a confusion rooted in the equation of equality between aesthetic sensibility in nature and the perception of its beauty as part of the vestigia Dei.
