A leading figure in the emerging field of extinction studies, Thom van Dooren puts philosophy into conversation with the natural sciences and his ethnographic encounters to vivify the cultural and ethical significance of modern-day extinctions. Unlike other meditations on the subject, _Flight Ways_ incorporates the particularities of real animals and their worlds, drawing philosophers, natural scientists, and general readers into the experience of living among and losing biodiversity. Each chapter of _Flight Ways_ focuses on a different species or group (...) of birds: North Pacific albatrosses, Indian vultures, an endangered colony of penguins in Australia, Hawaiian crows, and the iconic whooping cranes of North America. Written in eloquent and moving prose, the book takes stock of what is lost when a life form disappears from the world--the wide-ranging ramifications that ripple out to implicate a number of human and more-than-human others. Van Dooren intimately explores what life is like for those who must live on the edge of extinction, balanced between life and oblivion, taking care of their young and grieving their dead. He bolsters his studies with real-life accounts from scientists and local communities at the forefront of these developments. No longer abstract entities with Latin names, these species become fully realized characters enmeshed in complex and precarious ways of life, sparking our sense of curiosity, concern, and accountability toward others in a rapidly changing world.

Bundel essays over de invloed van de Duitse filosoof (1844-1900) op diverse cultuuruitingen.

This article focuses on a small population of house crows in the town of Hoek van Holland in the Netherlands, likely descendants of two birds that arrived by ship in the mid-1990s. In 2014, after twenty years of peaceful co-existence, the government began the process of eradicating this population. Just across the water from Hoek van Holland is the Port of Rotterdam – Europe’s largest port – and an “engine” for the global patterns of production, trade and consumption that are (...) today remaking our world, ushering in what many are calling “the Anthropocene.” Focusing on these crows and this port – in a way that is attuned to the broader placetimes that constitute our present – this paper explores the possibilities and limitations of hospitality as a basis for crafting shared worlds in difficult times.

This paper investigates when and how children figure out the force of modals: that possibility modals (e.g., _can_/_might_) express possibility, and necessity modals (e.g., _must_/_have to_) express necessity. Modals raise a classic subset problem: given that necessity entails possibility, what prevents learners from hypothesizing possibility meanings for necessity modals? Three solutions to such subset problems can be found in the literature: the first is for learners to rely on downward-entailing (DE) environments (Gualmini and Schwarz in J. Semant. 26(2):185–215, 2009 ); (...) the second is a bias for strong (here, necessity) meanings; the third is for learners to rely on pragmatic cues stemming from the conversational context (Dieuleveut et al. in Proceedings of the 2019 Amsterdam colloqnium, pp. 111–122, 2019a ; Rasin and Aravind in Nat. Lang. Semant. 29:339–375, 2020 ). This paper assesses the viability of each of these solutions by examining the modals used in speech to and by 2-year-old children, through a combination of corpus studies and experiments testing the guessability of modal force based on their context of use. Our results suggest that, given the way modals are used in speech to children, the first solution is not viable and the second is unnecessary. Instead, we argue that the conversational context in which modals occur is highly informative as to their force and sufficient, in principle, to sidestep the subset problem. Our child results further suggest an early mastery of possibility—but not necessity—modals and show no evidence for a necessity bias. (shrink)

For over a decade the Hawaiian crow, or ‘alalā, has been extinct in the wild, the only remaining birds living their lives in captivity. As the time for possible release approaches, questions of species identity – in particular focused on how birds have been changed by captivity – have become increasingly pressing. This article explores how identity is imagined and managed in this programme to produce ‘authentic’ crows. In particular, it asks what possibilities might be opened up by a move (...) beyond relatively static notions of how these birds ought to be, towards more performative understandings of species identity. This shift in focus prompts us to ask how we might take up the task of learning to be part of these birds’ own experiments in emergent forms of ‘crow-ness’, so that we might begin to craft vital new forms of ‘polite’ conservation in this era of incredible biodiversity loss.

The collection of essays in this special issue of Environmental Philosophy addresses the role that temporality, or lived time, should have in environmental philosophy, and especially ethics. The role of time in environmental ethics has largely been restricted to an empty container for human agency to do good or ill. By understanding time as material, produced, constructed, maintained, lived, multiple, and a more-than-human concern, the authors in this collection are able to ask which times are liveable for humans and non-humans (...) alike. Once the specificities of lived time are accounted for, it becomes clear that not all temporalities are identical and synchronous, and that environmental philosophy must attend to the ruptures in ecological time.

The Monty Hall dilemma is a notorious probability problem with a counterintuitive solution. There is a strong tendency to stay with the initial choice, despite the fact that switching doubles the probability of winning. The current randomised experiment investigates whether feedback in a series of trials improves behavioural performance on the MHD and increases the level of understanding of the problem. Feedback was either conditional or non-conditional, and was given either in frequency format or in percentage format. Results show that (...) people learn to switch most when receiving conditional feedback in frequency format. However, problem understanding does not improve as a consequence of receiving feedback. Our study confirms the dissociation between behavioural performance on the MHD, on one hand, and actual understanding of the MHD, on the other. We discuss how this dissociation can be understood.

‘We were driving through Death Valley, an American-Australian and two Aussies, taking the scenic route from Las Vegas to Santa Cruz.’ This multi-voiced account of multispecies encounters along a highway takes up the challenge of playful and humorous writing that is as well deeply serious and theoretically provocative. Our travels brought us into what Donna Haraway calls the contact zone: a region of recognition and response. The contact zone is a place of significant questions: ‘Who are you, and so who (...) are we? Here we are, and so what are we to become?’ Events were everything in this ecology of play, in which the movements of all the actors involved the material field in its entirety. We were brought into dances of approach and withdrawal, dances emerging directly, to paraphrase Brian Massumi, from the dynamic relation between a myriad of charged particles. (shrink)

Causal eliminativists maintain that all causal talk is false. The prospects for such a view seem to be stymied by an indispensability argument, charging that any agent must distinguish between effective and ineffective strategies, and that such a distinction must commit that agent to causal notions. However, this argument has been under-explored. The contributions of this paper are twofold: first, I provide a thorough explication of the indispensability argument and the various ways it might be defended. Second, I point to (...) an important limitation in the argument and suggest that it does not give us sufficient reason to reject eliminativism. In support of this last claim, I show that the distinction between effective and ineffective strategies could perfectly well be grounded in a counterfactual rather than a causal decision theory and argue that there are fully adequate explanations of how we could come to make the requisite counterfactual judgments that need not invoke causal concepts.

Both the concept of a Darwinian tree of life (TOL) and the possibility of its accurate reconstruction have been much criticized. Criticisms mostly revolve around the extensive occurrence of lateral gene transfer (LGT), instances of uptake of complete organisms to become organelles (with the associated subsequent gene transfer to the nucleus), as well as the implications of more subtle aspects of the biological species concept. Here we argue that none of these criticisms are sufficient to abandon the valuable TOL concept (...) and the biological realities it captures. Especially important is the need to conceptually distinguish between organismal trees and gene trees, which necessitates incorporating insights of widely occurring LGT into modern evolutionary theory. We demonstrate that all criticisms, while based on important new findings, do not invalidate the TOL. After considering the implications of these new insights, we find that the contours of evolution are best represented by a TOL. (shrink)

According to ontological nihilism nothing exists. A recent argument purports to show that this view is indefensible, since its most plausible formulations are tacitly committed to quantificational claims that are inconsistent with the nihilist's view that there aren't any existents. I show that this objection begs the question against the nihilist. The objector's argument relies on an equivalence principle implying that claims which nihilists regard as non-quantificational should nonetheless be interpreted as equivalent to quantified claims, given that both kinds of (...) assertion are assertible in the same contexts. This style of reasoning is supported by considerations of charity, which suggest that similarities in inter-personal patterns of language use provide evidence of similarity in the semantic content of speakers' utterances. However, related considerations also suggest that intra-personal patterns of language use constitute significant semantic evidence of the same kind. When we appreciate this and further recognize that nihilists are disposed to assert the negation of any positive, quantified claim, we see that it is too much to expect principles of semantic interpretation based on considerations of charity to decisively refute nihilism. This result has interesting metametaphysical implications concerning the role and scope of analogous arguments based on principles of interpretive charity. (shrink)

Postnatally, heart muscle cells almost completely lose their ability to divide, which makes their loss after trauma irreversible. Potential repair by cell grafting or mobilizing endogenous cells is of particular interest for possible treatments for heart disease, where the poor capacity for cardiomyocyte proliferation probably contributes to the irreversibility of heart failure. Knowledge of the molecular mechanisms that underly formation of heart muscle cells might provide opportunities to repair the diseased heart by induction of (trans) differentiation of endogenous or exogenous (...) cells into heart muscle cells. We briefly review the molecular mechanisms involved in early development of the linear heart tube by differentiation of mesodermal cells into heart muscle cells. Because the initial heart tube does not comprise all the cardiac compartments present in the adult heart, heart muscle cells are added to the distal borders of the tube and within the tube. At both distal borders, mesodermal cell are recruited into the cardiac lineage and, within the heart tube, muscular septa are formed. In this review, the relative late additions of heart muscle cells to the linear heart tube are described and the potential underlying molecular mechanisms are discussed. BioEssays 26:248–261, 2004.

The objective of the new series, "Molecular Biology, Biochemistry and Biophysics", of which this brochure forms the first volume, is to produce more than another compilation of data. It is hoped that the new series will help the individual "specialist" keep abreast of important developments in the natural sciences at the molecular and subcellular level in fields complementary to his own. The predominant aim is not so much to increase the ever-growing body of information in an encyclopedic fashion but rather (...) to give, in addition to a well rounded factual presentation of subjects which have reached a degree of maturation, a leitmotiv developed by the individual authors from a more personal point of view. The reader should thus be able to use these mono graphs not only for acquisition of knowledge but as a source of further motiva tion in his own work. This latter and more consequential aim of the monograph series is one of the reasons for presenting here a most unusual talk which should enable the reader to sit back and view his own efforts in the context of science and creative attempts as a whole. The lecture is the virtually unknown inaugural address of the Dutch physical chemist JACOBUS HENRICUS VAN'T HOFF. As is shown in his short biography presented on pages 3 and 4 the principal thoughts of the molecular biologist of today are akin to his own and he clearly recognized the universality of molecular life processes.

Summary In 1874, the Dutch chemist and Nobel prizewinner Jacobus Henricus van 't Hoff (1852?1911) laid the foundations for stereochemistry with a publication in which he openly suggested that molecules were real physical entities with a three-dimensional structure. He visualized this new spatial concept with illustrations, but also with the help of small cardboard molecular models, which he made himself. Some of these models have survived the ravages of time and are among the oldest molecular models in the world (...) still in existence. What is more, they are the first material models of a three-dimensional molecular structure ever made. This article describes the surviving Van 't Hoff models, kept in Museum Boerhaave in Leiden and in the Deutsches Museum in Munich. Special attention is paid to the use of these models and the specific purposes they served. A closer examination of the models and their context reveals that they had an essential part to play in the early development and spread of Van 't Hoff's stereochemistry theory: he put his molecular models not only to versatile use as didactic tools, scientific instruments, and precursors to experimental proof, but also as devices to persuade other scientists of the usefulness of his theory.

Im Jahr 2013 feiern die gelehrte und die politische Welt den 500. Jahrestag des Erscheinens von "Der Fürst ". Ohne Übertreibung kann man diese Schrift von Niccolò Machiavelli als einen der großen Schlüsseltexte in der Geschichte der politischen Philosophie bezeichnen. Nach dem schon geflügelten Ausdruck „Machiavellismus“ soll sich Machiavelli für eine Machtpolitik eingesetzt haben, die, von aller moralischen Verpflichtung losgelöst, ebenso rücksichts- wie skrupellos agiere. Machiavelli plädiert aber nicht für eine Entmoralisierung der Politik, vielmehr stellt er sich einer strukturellen Komplikation. (...) Sie beschwört einen Konflikt von zwei verschiedenen Moralen herauf, vom Staatswohl und von der für das persönliche Leben gültigen, der personalen Moral. Für diesen Konflikt schlägt er eine Prioritätsregel vor. Solange es nur möglich ist, bleibt es auch dem Herrscher verboten, vom Guten, zu verstehen als personale Moral, abzuweichen. Allein dort, wo die „menschliche“ Waffe nicht ausreicht, darf man auf die „Gewalt der Tiere“ zurückgreifen; nur wo die Macht der Gesetze nicht genügt, soll man die Kraft des Löwen mit der List des Fuchses verbinden. "Der Fürst" handelt von einem Herrscher, der unter realen, das heißt bei Machiavelli stets: schlechtesten Bedingungen, dennoch sein Amt relativ gut versieht. Diesen und vielen anderen Aspekten widmet sich der neue „Klassiker-Auslegen“-Band in zwölf detailreichen Analysen, die von international anerkannten Philosophen und Machiavelli-Forschern verfaßt wurden. Die einzelnen Kapitel des Werks werden in schlüssigen Interpretationen dargestellt. Abgerundet wird der Band durch Erläuterungen zur politischen Philosophie der Renaissance, zum Bezug zu Machiavellis Gesamtwerk und zur vielschichtigen Rezeptionsgeschichte von "Der Fürst". Mit Beiträgen von: Erica Benner, Dirk Brantl, Rolf Geiger, Martin van Gelderen, Otfried Höffe, Mikael Hörnqvist, Andreas Kablitz, Giovanni Panno, Alessandro Pinzani und Peter Schröder. (shrink)

Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890 models of Sachse. What is unique in these two case studies is that both models were not only folded, but were also conceptualized mathematically. When viewed in light of the chemical research of that period not only were both of (...) these aspects, considered in their singularity, exceptional, but also taken together may be thought of as a subversion of the way molecules were chemically investigated in the 19th century. Concentrating on this unique shared characteristic in the models of van ‘t Hoff and the models of Sachse, this paper deals with the shifts and displacements between their operational methods and existence: between their technical and epistemological aspects and the fact that they were folded, which was forgotten or simply ignored in the subsequent development of chemistry.

J. H. van 't Hoff's 1874 Dutch pamphlet, in which he proposed the spatial arrangement of atoms in a molecule, is one of the most significant documents in the history of chemistry. This essay presents a new narrative of Van 't Hoff's early life and places the appearance of the pamphlet within the context of the 'second golden age' of Dutch science. We argue that the combination of the reformed educational system in The Netherlands, the emergence of graphical (...) molecular modelling within the theoretical and practical culture of chemistry during the 1860s and 1870s, as well as Van 't Hoff's own personal research trajectory, formed the background to his unprecedented attribution of spatial meaning to the traditional concept of atomic 'arrangement'. We also present a new English translation of the pamphlet, for we have found that the existing translation, published by G. M. Richardson in 1901, contains many errors, changes and omissions. The new version offers a more accurate rendition in English of Van 't Hoff's style and argument. (shrink)
