Organizational ecology is commonly seen as a Darwinian research program that seeks to explain the diversity of organizational structures, properties and behaviors as the product of selection in past social environments in a similar manner as evolutionary biology seeks to explain the forms, properties and behaviors of organisms as consequences of selection in past natural environments. We argue that this explanatory strategy does not succeed because organizational ecology theory lacks an evolutionary mechanism that could be identified as the principal cause of organizational diversity. The “evolution” of organizational populations by means of selection, which organizational ecologists put forward as the mechanism responsible for the extant diversity of organizational forms, is not evolution in any proper sense, because organizational populations do not have what it takes to participate in evolutionary processes. This implies that organizational ecology is not a Darwinian research program and that it cannot explain organizational diversity

Natural kinds have been a constant topic in philosophy throughout its history, but many issues pertaining to natural kinds still remain unresolved. This paper considers one of these issues: the epistemic role of natural kinds in scientific investigation. I begin by clarifying what is at stake for an individual scientific field when asking whether or not the field studies a natural kind. I use an example from life science, concerning how biologists explain the similar body shapes of fish and cetaceans, to show that natural kinds play a central epistemic role in scientific explanations that cannot be delegated to other explanatory factors. A task for philosophy, then, is to come up with a theory of natural kinds that adequately accounts for the epistemic role of natural kinds in science. After having sketched the spectrum of available philosophical theories of natural kinds, I argue that none of the available theories adequately performs this task and that therefore the search is still open for a theory that does.

There is an interesting parallel between two debates in different domains of contemporary analytic philosophy. One is the endurantism– perdurantism, or three-dimensionalism vs. four-dimensionalism, debate in analytic metaphysics. The other is the debate on the species problem in philosophy of biology. In this paper I attempt to cross-fertilize these debates with the aim of exploiting some of the potential that the two debates have to advance each other. I address two issues. First, I explore what the case of species implies regarding the feasibility of particular positions in the endurantism– perdurantism debate. I argue that the case of species casts doubt on the recent claim that three-dimensionalism and four-dimensionalism are equivalent descriptions of the same underlying reality. Second, and conversely, I examine whether the metaphysical worry about three-dimensionalism and four-dimensionalism can help us to better understand the nature of biological species. I show that analyzing the thesis that species are individuals against the background of the endurantism– perdurantism debate allows us to explicate two different ways in which this thesis can be interpreted

This paper compares two approaches that attempt to explain the origin of life, or biogenesis. The more established approach is one based on chemical principles, whereas a new, yet not widely known approach begins from a physical perspective. According to the first approach, life would have begun with—often organic—compounds. After having developed to a certain level of complexity and mutual dependence within a non-compartmentalised organic soup, they would have assembled into a functioning cell. In contrast, the second, physical type of approach has life developing within tiny compartments from the beginning. It emphasises the importance of redox reactions between inorganic elements and compounds found on two sides of a compartmental boundary. Without this boundary, “life” would not have begun, nor have been maintained; this boundary—and the complex cell membrane that evolved from it—forms the essence of life.

A major issue in philosophical debates on the species problem concerns the opposition between two seemingly incompatible views of the metaphysics of species: the view that species are individuals and the view that species are natural kinds. In two recent papers in this journal, Olivier Rieppel suggested that this opposition is much less deep than it seems at first sight. Rieppel used a recently developed philosophical account of natural kindhood, namely Richard Boyd’s “homeostatic property cluster” theory, to argue that every species taxon can be conceived of as an individual that constitutes the single member of its own specific natural kind. In this paper I criticize Rieppel’s approach and argue that it does not deliver what it is supposed to, namely an account of species as kinds about which generalized statements can be made.

The more one reads about the topic of natural kinds, the more one is reminded of that famous scene in The Hitchhiker’s Guide to the Galaxy in which Deep Thought—after a mere 7.5 million years of doing calculations—reveals that the answer to the Ultimate Question of Life, the Universe and Everything was 42. Faced with bewildered reactions from the eager audience, Deep Thought explains: “I think the problem, to be quite honest with you, is that you’ve never actually known what the question is” .In the case of the growing literature on natural kinds, it is easy to get a feeling that something similar is going on. While philosophers keep advancing novel accounts of natural kinds, at the same time there is considerable disagreement about what exactly the problem is that such accounts should solve. To some, natural kinds are real kinds in nature that exist in the world independently of human interests and practices. At the very least, they are human-made kinds that correspon ..

Fragt man heute Vertreter verschiedener Disziplinen nach der Bedeutung des Hannoveraner Universalgelehrten Gottfried Wilhelm Leibniz, so hort man jeweils immer wieder: Leibniz hat Bedeutendes fur unser Fach geleistet. Leibniz beeindruckt nicht nur durch die Exzellenz seiner Leistung, sondern auch durch die Breite seiner Betatigungsfelder. Der aus einer Ringvorlesung an der Leibniz Universitat Hannover hervorgegangene Band fuhrt nun an die Vielfalt der von Leibniz ausgehenden der Leistungen und Anregungen heran. Insbesondere behandeln die Beitrage die Bedeutung von Leibniz fur die Geschichtswissenschaft, die Theologie, die Philosophie, die Rechtswissenschaft und Juristerei, die Politikberatung, das Versicherungswesen, die Mathematik, die Ingenieurwissenschaften und die Sprachwissenschaft. Abgerundet wird der Band durch eine Einfuhrung von Werner Eisner und eine biographische Skizze aus der Feder von Eike Christian Hirsch.

Despite many years of discussion, the species problem has still not been adequately resolved. Why is this the case? Here I discuss two recent suggested answers to this question that place the blame on the species problem's empirical aspects or on its philosophical aspects. In contrast, I argue that neither of these two faces of the species problem constitute the principal cause of the species problem's persistence. Rather, they are merely symptoms of the real cause: the species problem has not yet gone away because of a failure to recognize that not one but a number of distinct concepts are at the heart of the problem. To illustrate this point, a recently proposed solution to the problem is examined: the suggestion to understand the concept of species as a family resemblance concept.

This article, which is intended both as a position paper in the philosophical debate on natural kinds and as the guest editorial to this thematic issue, takes up the challenge posed by Ian Hacking in his paper, “Natural Kinds: Rosy Dawn, Scholastic Twilight.” Whereas a straightforward interpretation of that paper suggests that according to Hacking the concept of natural kinds should be abandoned, both in the philosophy of science and in philosophy more generally, we suggest that an alternative and less fatalistic reading is also possible. We argue that abandoning the concept of natural kinds would be premature, as it still can do important work. Our concern is with the situation in the (philosophy of the) life sciences. Against the background of this concern we attempt to set something of an agenda for future research on the topic of natural kinds in the (philosophy of the) life sciences

Economics and social sciences in general have a long tradition of using theories, models, concepts, and so forth borrowed from the natural sciences to describe and explain the properties and behaviours of economic and social entities. However, unwarranted application of theoretical elements from the natural sciences in the economic/social domain can have adverse consequences for organisations, their employees and society in general. Focusing on biology and organisation studies, we discuss the general problems that may arise when theoretical elements from natural science are applied in the economic/social domain. We examine one particular case, the organisational ecology research programme, and we argue that organisational ecology rests on the metaphorical, rather than literal, use of the notion of evolution. We conclude by showing how the use of the evolutionary metaphor in organisation theory can have adverse consequences for both managerial practice and society in general.
