Between 1937 and 1940 the Taxonomic Principles Committee of the newly-founded Association for the Study of Systematics in Relation to General Biology (later the Systematics Association) attempted to define the relationship between evolution and taxonomy. The people who took part in the discussion were W.T. Calman, C.R.P. Diver, J.S.L. Gilmour, J.S. Huxley, W.D. Lang, J.R. Norman, R. Melville, O.W. Richards, M.A. Smith, T.A. Sprague, H. Hamshaw Thomas, W.B. Turrill, B.P. Uvarov, A.F. Watkins, E.I. White, and A.J. Wilmott. Most of the (...) botanists asserted that taxonomy was a practical matter to be kept distinct from phylogenetic speculation, and most of the zoologists insisted that taxonomists must strive to represent evolution if they wished to be scientific. The disagreement seemed to be hardening rather than approaching compromise when World War Two stopped the committee's work. (shrink)

Species that died without leaving descendants Darwin called ‘utterly extinct’. They far outnumber the ancestors of all living things, so they resemble the dark matter of modern cosmology, which far outweighs visible matter. He realized in 1837 that their absence is what creates the groups in a natural classification. In his Notebook B he combined the idea that species multiply with the idea that ancestors' relatives must mostly be extinct. The fossil Megatherium was utterly extinct. The iconic branching ‘I think’ (...) diagram shows extinction causing the origin of genera by eliminating intermediate species. Darwin’s concept of taxonomic ranks, starting with the genus, was informed by his interaction with taxonomists. Based on his familiarity with demography, Darwin reasoned that the survival of transitional forms was unlikely, which helped him decide to focus at the species level. When drafting his theory in the 1840s, he left out these speculative ideas, but they emerged again in the 1850s when he realized his theory needed a cause for branches to diverge. His ecological answer worked at the species level, but his Principle of Divergence was unconvincing at higher taxonomic levels. In the Origin, Darwin repeatedly insisted on the importance of utter extinction. (shrink)

The word ``deme'' was coined by the botanists J.S.L. Gilmour and J.W.Gregor in 1939, following the pattern of J.S. Huxley's ``cline''. Its purposewas not only to rationalize the plethora of terms describing chromosomaland genetic variation, but also to reduce hostility between traditionaltaxonomists and researchers on evolution, who sometimes scorned eachother's understanding of species. A multi-layered system of compoundterms based on deme was published by Gilmour and J. Heslop-Harrison in1954 but not widely used. Deme was adopted with a modified meaning byzoologists (...) leading the evolutionary synthesis – Huxley, Simpson, Wright,and Mayr. Connections are shown between Gilmour's ideas around definingthe deme, his role in founding the Systematics Association, and his chapter``Taxonomy and Philosophy'' in the book The New Systematics. Thishistorical episode raises questions about the role of carefully-definedwords in scientific practice. (shrink)

Zoologist A. J. Cain began historical research on Linnaeus in 1956 in connection with his dissatisfaction over the standard taxonomic hierarchy and the rules of binomial nomenclature. His famous 1958 paper ‘Logic and Memory in Linnaeus's System of Taxonomy’ argues that Linnaeus was following Aristotle's method of logical division without appreciating that it properly applies only to ‘analysed entities’ such as geometric figures whose essential nature is already fully known. The essence of living things being unanalysed, there is no basis (...) on which to choose the right characters to define a genus nor on which to differentiate species. Yet Cain's understanding of Aristotle, which depended on a 1916 text by H. W. B. Joseph, was fatally flawed. In the 1990s Cain devoted himself to further historical study and softened his verdict on Linnaeus, praising his empiricism. The idea that Linnaeus was applying an ancient and inappropriate method cries out for fresh study and revision. (shrink)

The essentialism story is a version of the history of biological classification that was fabricated between 1953 and 1968 by Ernst Mayr, who combined contributions from Arthur Cain and David Hull with his own grudge against Plato. It portrays pre-Darwinian taxonomists as caught in the grip of an ancient philosophy called essentialism, from which they were not released until Charles Darwin's 1859 Origin of Species. Mayr's motive was to promote the Modern Synthesis in opposition to the typology of idealist morphologists; (...) demonizing Plato served this end. Arthur Cain's picture of Linnaeus as a follower of 'Aristotelian' (scholastic) logic was woven into the story, along with David Hull's application of Karl Popper's term, 'essentialism', which Mayr accepted in 1968 as a synonym for what he had called 'typological thinking'. Although Mayr also pointed out the importance of empiricism in the history of taxonomy, the essentialism story still dominates the secondary literature. The history of the first telling of the essentialism story exposes its scant basis in fact. (shrink)

The current widespread belief that taxonomic methods used before Darwin were essentialist is ill-founded. The essentialist method developed by followers of Plato and Aristotle required definitions to state properties that are always present. Polythetic groups do not obey that requirement, whatever may have been the ontological beliefs of the taxonomist recognizing such groups. Two distinct methods of forming higher taxa, by chaining and by examplar, were widely used in the period between Linnaeus and Darwin, and both generated polythetic groups. Philosopher (...) William Whewell congratulated pre-Darwinian taxonomists for not adhering to the rigid ideal of definition used in the mathematical sciences. What he called the method of types is here called the method of exemplars because typology has been equated with essentialism, whereas the use of a type species as the reference point or prototype for a higher category was a practice inconsistent with essentialism. The story that the essentialism of philosophers dominated the development of systematics may prove to be a myth. (shrink)

Reading the Shape of Nature vividly recounts the turbulent early history of the Museum of Comparative Zoology at Harvard and the contrasting careers of its founder Louis Agassiz and his son Alexander. Through the story of this institution and the individuals who formed it, Mary P. Winsor explores the conflicting forces that shaped systematics in the second half of the nineteenth century. Debates over the philosophical foundations of classification, details of taxonomic research, the young institution's financial struggles, and (...) the personalities of the men most deeply involved are all brought to life. In 1859, Louis Agassiz established the Museum of Comparative Zoology to house research on the ideal types that he believed were embodied in all living forms. Agassiz's vision arose from his insistence that the order inherent in the diversity of life reflected divine creation, not organic evolution. But the mortar of the new museum had scarcely dried when Darwin's Origin was published. By Louis Agassiz's death in 1873, even his former students, including his son Alexander, had defected to the evolutionist camp. Alexander, a self-made millionaire, succeeded his father as director and introduced a significantly different agenda for the museum. To trace Louis and Alexander's arguments and the style of science they established at the museum, Winsor uses many fascinating examples that even zoologists may find unfamiliar. The locus of all this activity, the museum building itself, tells its own story through a wonderful series of archival photographs. (shrink)

The current picture of the history of taxonomy incorporates A. J. Cain's claim that Linnaeus strove to apply the logical method of definition taught by medieval followers of Aristotle. Cain's argument does not stand up to critical examination. Contrary to some published statements, there is no evidence that Linnaeus ever studied logic. His use of the words “genus” and “species” ruined the meaning they had in logic, and “essential” meant to him merely “taxonomically useful.” The essentialism story, a narrative that (...) has most pre-Darwinian biologists steeped in the world view of Plato and Aristotle, is ill-founded and improbable.

Thomas Henry Huxley and Charles Darwin discovered in 1857 that they had a fundamental disagreement about biological classification. Darwin believed that the natural system should express genealogy while Huxley insisted that classification must stand on its own basis, independent of evolution. Darwin used human races as a model for his view. This private and long-forgotten dispute exposes important divisions within Victorian biology. Huxley, trained in physiology and anatomy, was a professional biologist while Darwin was a gentleman naturalist. Huxley agreed with (...) John Stuart Mill's rejection of William Whewell's sympathy for Linnaeus. The naturalists William Sharp Macleay, Hugh Strickland, and George Waterhouse worked to distinguish two kinds of relationship, affinity and analogy. Darwin believed that his theory could explain the difference. Richard Owen introduced the distinction between homology and analogy to anatomists, but the word homology did not enter Darwin's vocabulary until 1848, when he used the morphological concept of archetype in his work on Cirripedia. Huxley dropped the word archetype when Richard Owen linked it to Plato's ideal forms, replacing it with common plan. When Darwin wrote in the Origin of Species that the word plan gives no explanation, he may have had Huxley in mind. Darwin's preposterous story in the Origin about a bear giving birth to a kangaroo, which he dropped in the second edition, was in fact aimed at Huxley. (shrink)

Early in this century, only a few biologists accepted that natural selection was the chief cause of evolution, until the independent calculations of John Burdon Sanderson Haldane (1892–1964), Sewall Wright and R. A. Fisher demonstrated that ideal populations subject to Mendel's laws could behave as Darwin had said they would. Evolutionary theorist John Maynard Smith, a student of Haldane's, has raised the question of why Haldane, who was no naturalist, took up the subject of evolution, and he suggests that the (...) answer may have to do with Haldane's lively interest in religion. In fact Maynard Smith's answer has much more evidence in its favour than he knew. (shrink)

Carl Becker's classic 1931 address "Everyman his own historian" holds lessons for historians of science today. Like the professional historians he spoke to, we are content to display the Ivory- Tower Syndrome, writing scholarly treatises only for one another, disdaining both the general reader and our natural readership, scientists. Following his rhetoric, I argue that scientists are well aware of their own historicity, and would be interested in lively and balanced histories of science. It is ironic that the very professionalism (...) that ought to equip us to write such histories has imposed on us a powerful taboo that renders us unable to do so. We who count ourselves sophisticated in describing the effects of social forces upon past scientists have been remarkably unconscious of the ways our own practices are being shaped by our need to distinguish ourselves from scientists who write history. Our fear of presentism in general and Whig history in particular is really a taboo, that is, an excessive avoidance enforced by social pressure. It succeeds at making our work distinct from histories written by scientists, but at the awful cost of blotting out the great fact of scientific progress. Scientists may be misguided in expecting us to celebrate great men, but they are right to demand from historians an analysis of the process of testing and improvement that is central to science. If progress in general is a problematic term, we could label the process "emendation.". (shrink)

Mary Winsor (2003) argues against the received view that pre-Darwinian taxonomy was characterized mainly by essentialism. She argues, instead, that the methods of pre-Darwinian taxonomists, in spite of whatever their beliefs, were that of clusterists, so that the received view, propagated mainly by certain modern biologists and philosophers of biology, should at last be put to rest as a myth. I argue that shes right when it comes to higher taxa, but wrong when it comes the most important (...) category of all, the species category. (shrink)

This chapter uses Marx’s credit theory in Comments on James Mill and Freire’s theory of the banking model of education from Pedagogy of the Oppressed to argue that the confluence of massive student debt and structures of “banking” pedagogy in contemporary American higher education places many university students in a unique position of dehumanization. The material limitations brought about by the loan are compounded by the social limitations of a resulting push toward productivity in education. Students with loan debt are (...) driven in the direction of business and pre-professional majors and away from the humanities and other fields which would facilitate students’ abilities to critically question the dehumanizing aspects of their situation.

Science as Salvation discusses the high spiritual ambitions which tend to gather round the notion of science. Officially, science claims only the modest function of establishing facts. Yet people still hope for something much grander from it--namely, the myths by which to shape and support life in an increasingly confusing age. Our faith in science is abused by some scientists whose adolescent fantasies have spilled over into their professional lives. Salvation, immortality, mastery of the universe, humans without bodies, and intelligent (...) self-reproducing computers are just some of the notions and speculations that are now found--not on the pages of science fiction--but on the pages of science itself. The danger is that these concepts are given to a myth-hungry public who turn to science now that religion has lost its ability to create myth. Science as Salvation discusses the function and meaning of such fantasies. Midgley examines the need for and the use of myth in science, and how science and religion are related. She argues that we need to develop a realistic understanding of scientific imagination and its importance. Taking them seriously as symptoms of a genuine myth-hunger, it suggests that the proper function of science may need to include wider perspectives, which would make it plain that such desperate, compensatory dramas are unnecessary.

In the first part of this paper Hugh Rayment-Pickard challenges Mark Bevir's assumption that Derrida does not care about historical or other kinds of truth. A consideration of Derrida's early work on Husserl shows deconstruction to be a kind of skepsis or epoche launched in search of the truth. Yet deconstruction reveals the truth as ‘undecidable’, which means that Derrida's commitment to the truth must take the form of ‘faith’. The second part of the paper considers an example of (...) definite intentional meaning given in Mark Bevir's Logic: Petrarch's ascent of Mont Ventoux. On examination, Petrach's motivation can be seen to be radically divided between secular and religious concerns, a split vividly illustrated in his imaginary dialogue with St Augustine: The Secret. Finally, Rayment-Pickard looks briefly at Derrida's own dialogue with St Augustine, ‘Circumfession’, which also argues that human intentions are irreducibly complex and plural. (shrink)

Some commentators have condemned Kant’s moral project from a feminist perspective based on Kant’s apparently dim view of women as being innately morally deficient. Here I will argue that although his remarks concerning women are unsettling at first glance, a more detailed and closer examination shows that Kant’s view of women is actually far more complex and less unsettling than that attributed to him by various feminist critics. My argument, then, undercuts the justification for the severe feminist critique of Kant’s (...) moral project. (shrink)

Classical logic has proved inadequate in various areas of computer science, artificial intelligence, mathematics, philosopy and linguistics. This is an introduction to extensions of first-order logic, based on the principle that many-sorted logic (MSL) provides a unifying framework in which to place, for example, second-order logic, type theory, modal and dynamic logics and MSL itself. The aim is two fold: only one theorem-prover is needed; proofs of the metaproperties of the different existing calculi can be avoided by borrowing them from (...) MSL. To make the book accessible to readers from different disciplines, whilst maintaining precision, the author has supplied detailed step-by-step proofs, avoiding difficult arguments, and continually motivating the material with examples. Consequently this can be used as a reference, for self-teaching or for first-year graduate courses. (shrink)

Within contemporary penal philosophy, the view that punishment can only be justified if the offender is a moral agent who is responsible and hence blameworthy for their offence is one of the few areas on which a consensus prevails. In recent literature, this precept is associated with the retributive tradition, in the modern form of ‘just deserts’. Turning its back on the rehabilitative ideal, this tradition forges a strong association between the justification of punishment, the attribution of responsible agency in (...) relation to the offence, and the appropriateness of blame. By contrast, effective clinical treatment of disorders of agency employs a conceptual framework in which ideas of responsibility and blameworthiness are clearly separated from what we call ‘affective blame’: the range of hostile, negative attitudes and emotions that are typical human responses to criminal or immoral conduct. We argue that taking this clinical model of ‘responsibility without blame’ into the legal realm offers new possibilities. Theoretically, it allows for the reconciliation of the idea of ‘just deserts’ with a rehabilitative ideal in penal philosophy. Punishment can be reconceived as consequences—typically negative but occasionally not, so long as they are serious and appropriate to the crime and the context—imposed in response to, by reason of, and in proportion to responsibility and blameworthiness, but without the hard treatment and stigma typical of affective blame. Practically, it suggests how sentencing and punishment can better avoid affective blame and instead further rehabilitative and related ends, while yet serving the demands of justice. (shrink)

Moral and legal philosophy are too entangled: moral philosophy is prone to model interpersonal moral relationships on a juridical image, and legal philosophy often proceeds as if the criminal law is an institutional reflection of juridically imagined interpersonal moral relationships. This article challenges this alignment and in so doing argues that the function of the criminal law lies not fundamentally in moral blame, but in regulation of harmful conduct. The upshot is that, in contrast to interpersonal relationships, the criminal law (...) cannot lose its standing to blame through institutional analogues of hypocrisy, complicity, and meddling. Rather, certain forms of structural and severe historical and contemporary injustice point to the question of the overall legitimacy of state authority. (shrink)

Ad blockers are a category of computer software program, typically run as web browser extensions, that allow users to selectively eliminate advertisements from the webpages they visit. Many people have alleged that using an ad blocker is morally problematic because it is bad for content providers and consumers, and it is morally akin to theft. We disagree. In this paper, we defend an independent argument for the conclusion that using an ad blocker is morally permissible. In doing so, we respond (...) to the criticisms that ad blocking is bad for content providers and consumers, that it is morally akin to theft, and that it violates a contract between consumers and web publishers.

This important book charts the development of philosophical thinking about history over the past 250 years, combining extracts from key texts with new explanatory and critical discussion. The book is designed to make the work of thinkers such as Hume, Herder, Hegel, Dilthey, Nietzsche, Heidegger and Foucault accessible to students with no prior knowledge of Western philosophy. An introductory section is followed by nine further chapters exploring contrasting schools of thought. The volume reveals the origins of contemporary trends in the (...) discipline and relates wider philosophical reflections to the study of history itself. It also points to connections between philosophy of history and literary and cultural theory which have developed in recent decades. (shrink)

We suggest edits to Part Four of the Ethical and Religious Directives (ERDs) to help the US bishops address and clarify essential Church teachings on specific beginning-of-life issues facing Catholic health care today. As a teaching tool, Part Four must be updated so that Catholic health care professionals and the lay faithful can understand and apply Church teachings to new ethical challenges. Further, more direction and clarity from the ERDs is needed in applying general principles to assisted procreative technologies, pre- (...) and post-viability induction of labor, ectopic pregnancies, genetic screening and diagnosis, and contraception. Catholic health care clinicians and administrators also need to receive ongoing instruction on the ERDs’ teachings as well as the theological and philosophical rationales that undergird them.

Childhood cancer incidence is rising, affecting a growing proportion of elementary school students. For most of these children, school attendance can be limited by hospitalisations, treatments and side effects. However, little is yet known about the educational needs and experiences of this population. This phenomenological study explored the school experiences of 10 6- to 12-year-old children with cancer as they underwent chemotherapy. Results revealed perceptions that attending school in the hospital or home during cancer treatment is essentially lonely, confusing and (...) “different”. These perceptions intertwined to illuminate five themes: school should involve fun activities; group educational formats are preferable; old school is the “best school”; being a “good student” is important during treatment; and attending school is complicated during treatment. Therefore, hospital-based and homebound schooling programmes should integrate socially interactive and cognitively engaging curriculum to best support the learning needs of this population. (shrink)

Drug use and drug addiction are severely stigmatised around the world. Marc Lewis does not frame his learning model of addiction as a choice model out of concern that to do so further encourages stigma and blame. Yet the evidence in support of a choice model is increasingly strong as well as consonant with core elements of his learning model. I offer a responsibility without blame framework that derives from reflection on forms of clinical practice that support change and recovery (...) in patients who cause harm to themselves and others. This framework can be used to interrogate our own attitudes and responses, so that we can better see how to acknowledge the truth about choice and agency in addiction, while avoiding stigma and blame, and instead maintaining care and compassion alongside a commitment to working for social justice and good.

In the Philippines, all transplant centers are mandated by the Department of Health (DOH) to have a Hospital Transplant Ethics Committee (HTEC) to ensure that donations are altruistic, voluntary and free of coercion/commercial transactions. This study was undertaken primarily to describe the organizational and functional profile of existing HTECs and identify areas for improvement. This is a descriptive cross‐sectional study. There was variation in their logistical arrangements (support from hospital, filing systems, office spaces), operations (length and frequency of meetings, number (...) of referrals) and membership (composition, qualifications, occupation, training). The approval rate for donor‐recipient pairs is high with the majority of cases made by living non‐related donors. Appropriate reasons were cited for rejection. The perception of HTECs is that they are competent and confident in their decision‐making. However, there is a need to standardize HTEC composition, provide operating procedures and additional training which can be done by the DOH. (shrink)

Addiction is standardly characterized as a neurobiological disease of compulsion. Against this characterization, I argue that many cases of addiction cannot be explained without recognizing the value of drugs to those who are addicted; and I explore in detail an insufficiently recognized source of value, namely, a sense of self and social identity as an addict. For people who lack a genuine alternative sense of self and social identity, recovery represents an existential threat. Given that an addict identification carries expectations (...) of continued consumption despite negative consequences, there is therefore a parsimonious explanation of why people who identify as addicts continue to use drugs despite these consequences: they self‐identify as addicts and that is what addicts are supposed to do. I conclude by considering how it is nonetheless possible to overcome addiction despite this identity, in part by imagining and enacting a new one. Importantly, this possibility requires the availability of social support and material resources that are all too frequently absent in the lives of those who struggle with addiction. (shrink)
