The vision of natural kinds that is most common in the modern philosophy of biology, particularly with respect to the question whether species and other taxa are natural kinds, is based on a revision of the notion by Mill in A System of Logic. However, there was another conception that Whewell had previously captured well, which taxonomists have always employed, of kinds as being types that need not have necessary and sufficient characters and properties, or essences. These competing views employ (...) different approaches to scientific methodologies: Mill’s class-kinds are not formed by induction but by deduction, while Whewell’s type-kinds are inductive. More recently, phylogenetic kinds (clades, or monophyletic-kinds) are inductively projectible, and escape Mill’s strictures. Mill’s version represents a shift in the notions of kinds from the biological to the physical sciences. (shrink)

Genes are thought to have evolved from long-lived and multiply-interactive molecules in the early stages of the origins of life. However, at that stage there were no replicators, and the distinction between interactors and replicators did not yet apply. Nevertheless, the process of evolution that proceeded from initial autocatalytic hypercycles to full organisms was a Darwinian process of selection of favourable variants. We distinguish therefore between Neo-Darwinian evolution and the related Weismannian and Central Dogma divisions, on the one hand, and (...) the more generic category of Darwinian evolution on the other. We argue that Hull’s and Dawkins’ replicator/interactor distinction of entities is a sufficient, but not necessary, condition for Darwinian evolution to take place. We conceive the origin of genes as a separation between different types of molecules in a thermodynamic state space, and employ a notion of reproducers. (shrink)

Some time ago I wrote a paper about conceivability and knowledge. An anonymous referee rejected it on the grounds that the result had already been established in a short story by Jorge Luis Borges. Intrigued, I looked for the story but found no mention of it in Louis and Ziche’s extensive bibliography. I spent months consulting archives and electronic records to no avail. I had begun to doubt whether the story even existed when I had the curious good luck to (...) encounter Sir Thomas Browne of Pembroke College, Oxford, who assured me of the piece’s authenticity and introduced me to Brother Christian Rosenkreuz of Invisible College who in turn generously put me into correspondence with Borges himself. The literary defects in what follows reflect not a diminution of Borges’s undoubted power as a storyteller, but merely my limited ability as an amateur translator. Whatever the translation’s literary faults may be, I hope the story’s philosophical interest—i.e., an argument that ideal conceivers have higher-order knowledge of necessary truths—remains. [Trans.].

Features Covers the philosophical and historical development of the concept of "species" Documents that variation was recognized by pre-Darwinian scholars Includes a section on the debates since the time of the New Synthesis Better suited to non-philosophers Summary Over time the complex idea of "species" has evolved, yet its meaning is far from resolved. This comprehensive work is a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. Species is a (...) benchmark exploration and clarification of a concept fundamental to the past, present, and future of the natural sciences. In this edition, a section is added on the debate over species since the time of the New Synthesis, and brings the book up to date. A section on recent philosophical debates over species has also been added. This edition is better suited non-specialists in philosophy, so that it will be of greater use for scientists wishing to understand how the notion came to be that living organisms form species.

Species, or ‘the Species Problem’, is a topic in science, in the philosophy of science, and in general philosophy. There is not one, but many, species problems, and these are dealt with in this volume. Species are often thought of as units of biology, to be used in ecology, conservation, classification, and theory. The chapters in this book present opposing views on the current philosophical and conceptual issues of the Species Problem in biology. -/- Divided into four sections Theories and (...) Concepts, Practice and Methods, Ranks, Trees and Names, and Metaphysics and Epistemologies, the book is authored by systematists, philosophers, historians and working biologists, many leaders in their fields. Topics include Essentialism and individuals, speciation modes, theory and the species rank, nomenclature and diagnosis, scale of species, and ecology, conservation, and species. -/- Species Problems and Beyond aims to clarify the contemporary issues of the Species Problem. It is ideal for use in upper-level seminars and courses in Evolutionary Biology, Philosophy of Science, Philosophy of Biology, Systematics and Taxonomy, and Phylogenetics/Cladistics, and for any scholar in these fields.

The impact of neoliberal reforms of education systems on the work of teachers and school leaders, particularly in relation to high-stakes accountability frameworks, has been extensively studied in recent decades. One significant aspect of neoliberal schooling is the emergence of quasi-autonomous public schools (such as Academies in England, Charter Schools in the USA and Independent Public Schools in Australia), characterised by heterarchical governance models, the promotion of entrepreneurial leadership cultures, and the promotion of a discourse of pursuing educational equity by (...) means of ‘achievement for all’. This paper explores the emergence of a mode of teacher professionalism characteristic of these quasi-autonomous schools, and conceptualises this as being ‘neo-performative’. The neo-performative profession is shaped by the shift in the focus of the regulation and management of schools from ‘governing to governance’, and the consequential rise of the ‘responsibilised profession’, and marked by the emergence of an entrepreneurial model of school leadership. The paper argues that this new conceptualisation of teacher professionalism requires further, more focused, empirical study in order to explore how neoperformative teachers and school leaders articulate their vision of educational equity and social justice, and how they enact this vision in an increasingly intensified high-stakes accountability culture.

This study gathered preliminary baseline data on the moral development of journalists using the Defining Issues Test, an instrument based on Kohlberg's 6 stages. Results show that a sample of journalists scored 4th highest among professionals tested using the DIT. The journalists ranked behind seminarians/philosophers, medical students, and physicians but above dental students, nurses, graduate students, undergraduate college students, veterinary students, and adults in general. No significant differences were found between various groups of journalists, including men and women, and broadcast (...) and print journalists. The journalists in the study scored significantly higher on the 3 journalism-specific dilemmas than on 3 nonjournalism dilemmas. (shrink)

__Modernising School Governance__ examines the impact of recent market-based reforms on the role of governors in the English state education system. A focus of the book concerns how government and non-government demands for ‘strong governance’ have been translated to mean improved performance management of senior school leaders and greater monitoring and disciplining of governors. This book addresses fundamental questions about the neoliberal logic underpinning these reforms and how governors are being trained and responsibilised in new ways to enhance the integrity (...) of these developments. Drawing on large-scale research conducted over three years, the book examines the impact of these reforms on the day to day practices of governors and the diminished role of democracy in these contexts. Wilkins also captures the economic and political rationalities shaping the conduct of governors at this time and traces these expressions to wider structural developments linked to depoliticisation, decentralisation and disintermediation. This book addresses timely and original issues concerning the role of corporate planning and expert handling to state education at a time of increased school autonomy, shrinking local government support/oversight, and tight, centralised accountability. It will appeal to researchers and postgraduate students in disciplines of education, sociology, political science, public policy and management. It will also be of interest to researchers and policy makers from countries with similar or emerging quasi-market education systems. (shrink)

The terrorist threat remains a disturbing issue for the early 1990s. This book explores whether terrorism can ever be morally justifiable and if so under what circumstances. Professor Burleigh Taylor Wilkins suggests that the popular characterisation of terrorists as criminals fails to acknowledge the reasons why terrorists resort to violence. It is argued that terrorism cannot be adequately understood unless the collective responsibility of organised groups, such as political states, for wrongs allegedly done against the groups which the terrorists (...) represent is taken into account. Terrorism and Collective Responsibility provides an analysis of various models of collective responsibility, and it takes into account recent discussions of military responsibility and business ethics. The book also explores the problems that terrorism poses for the just war tradition. The arguments of prominent philosophers against terrorism are critically examined and the claim that terrorism necessarily violates the rights of innocent persons is considered. Wilkins sets forth an original definition of terrorism that is sure to provoke controversy. (shrink)

In this article, I use in-depth interviews with Black college students at two predominantly white universities to investigate the coconstruction of race, gender, and sexuality, and to examine intersectional identities as a dynamic process rather than bounded identity. I focus on Black college men’s talk about interracial relationships. Existing research documents Black women’s angry reactions to interracial relationships, but for Black men, interracial relationships present both problems and opportunities. I examine how Black men use two distinct forms of interracial talk— (...) “player” talk and “intimacy” talk—to negotiate racialized gendered stereotypes of Black men’s heterosexuality. By moving between forms of talk, Black men negotiate the identity tensions they face as Black upwardly mobile men. Player talk and intimacy talk both respond to and use racialized stereotypes, reworking the relationship between gender, race, and sexuality. In this case, disrupted racial boundaries uphold gender inequalities between men and women. (shrink)

This chapter contains sections titled: Progress and the Tree of History Discovering the Past Teleological Thinking References and Further Reading.

Arguments against essentialism in biology rely strongly on a claim that modern biology abandoned Aristotle's notion of a species as a class of necessary and sufficient properties. However, neither his theory of essentialism, nor his logical definition of species and genus (eidos and genos) play much of a role in biological research and taxonomy, including his own. The objections to natural kinds thinking by early twentieth century biologists wrestling with the new genetics overlooked the fact that species have typical developmental (...) cycles and most have a large shared genetic component. These are the "what-it-is-to-be" members of that species. An intrinsic biological essentialism does not commit us to Aristotelian notions, nor even modern notions, of essence. There is a long-standing definition of "species" and its precursor notions that goes back to the Greeks, and which Darwin and pretty well all biologists since him share, that I call the Generative Conception of Species. It relies on there being a shared generative power that makes progeny resemble parents. The "what-it-is-to-be" a member of that species is that developmental type, mistakes in development notwithstanding. Moreover, such "essences" have always been understood to include deviations from the type. Finally, I shall examine some implications of the collapse of the narrative about essences in biology.

It is often claimed that Margaret Cavendish was an anti-experimentalist who was deeply hostile to the activities of the early Royal Society—particularly in relation to Robert Hooke's experiments with microscopes. Some scholars have argued that her views were odd or even childish, while others have claimed that they were shaped by her gender-based status as a scientific ‘outsider’. In this paper I examine Cavendish's views in contemporary context, arguing that her relationship with the Royal Society was more nuanced than previous (...) accounts have suggested. This contextualized approach reveals two points: first, that Cavendish's views were not isolated or odd when compared with those of her contemporaries, and second, that the early Royal Society was less intellectually homogeneous than is sometimes thought. I also show that, although hostile to some aspects of experimentalism, Cavendish nevertheless shared many of the Royal Society's ambitions for natural philosophy, especially in relation to its usefulness and the importance of plain language as a means to disseminate new ideas.

Drawing on interviews, participant observation, and Internet postings, this article analyzes gender in a local Goth scene. These Goths use the confines of the subcultural scene, where they are relatively safe from outsider view, and the scene’s celebration of sexuality as resources to resist mainstream notions of passive femininity. This article probes the struggles of women in this Goth scene to examine the broader possibilities and limitations of strategies of active feminine sexuality in gaining gender egalitarianism. I argue that although (...) these women do transform sexual expectations and experiences, their gains are hampered by an overly narrow vision of gender egalitarianism that both obfuscates the broader landscape of gender inequality and blurs the reproduction of an ideological system in which romance trumps sex.

Gaven Kerr argues that Lonergan is a metaphysical realist but follows an inherently idealist method. Furthermore, Kerr claims, Lonergan’s isomorphism of cognitional and ontological elements does not hold, because ontological act is not parallel to cognitional judgment. In so arguing, however, Kerr conflates ontological act with efficient causality, misunderstands the nature of the parallel asserted by Lonergan’s isomorphism, and involves himself in a priori speculation about the implications of Lonergan’s method. An efficient cause is an extrinsic principle, whereas “act” names (...) an intrinsic constituent of contingent being. The parallel between ontological and cognitional composition, moreover, and the isomorphism of ontological and cognitional elements, are subtler than Kerr appreciates. The suspicion, finally, that Lonergan’s method is somehow inherently idealist is idle and not borne out by the facts. (shrink)

This paper focuses on the significance of the concept of noise for cognition and computation. The concept of noise was massively transformed in the twentieth century with the advent of information theory, cybernetics, and computer science, all of which provide formal accounts of information and noise centrally concerned with contingency. We show how the concept has changed from these classical formulations, through developments in mathematics (topology and topos theory), computing (interactive computing and univalent foundations), and cognitive science (predictive processing and (...) cognitive morphodynamics). Ultimately it argues for the central importance of noise not only within a topological conception of cognition and computation, but also in the transcendental-empirical torsion of image schemata and the social interactive elaboration of freedom.

I consider two essays by Joel Feinberg: his treatment of the moral obligation to obey the law, and his exploration of the evils of the Holocaust.

The longstanding species problem in biology has a history that suggests a solution, and that history is not the received history found in many texts written by biologists or philosophers. The notion of species as the division into subordinate groups of any generic predicate was the staple of logic from Aristotle through the middle ages until quite recently. However, the biological species concept during the same period was at first subtly and then overtly different. Unlike the logic sense, which relied (...) on definitions of the essence of both genus and species, biological species from the time of Epicurus were consistently considered to involve a reproductive element: in short, living species relied not on essential definitions, but on the generative cause, which might not be definable. I term this the generative conception of species: species were the generation by reproduction of form. This undercuts the claim that species before Darwin were essentialist, and divorces the notion of a type from that of essence. In fact, as late as the end of the nineteenth century, logicians explicitly treated biological “species” as a homonym only of logical essentialist species, and permitted considerable deviation from the type or form. At every point, species in logic were thought to be a subset, in effect, of some more general notion. I sketch a history of both philosophical and biological traditions of the species concept, before turning to the current conceptions. These are reconsidered in the light of this history, and in particular Mayr’s changing views are shown to be somewhat Whiggish, historiographically. Of the many touted biological species concepts, only one of which (Mayr’s) is called _the_ Biological Species Concept, none appears to capture all the relevant facts, intuitions, and operational requirements of biology. Cladistic conceptions, however, have much in common with the older philosophical literature, in that the natural group of cladism is the clade, or monophyletic group. After considering the Individuality Thesis, and the metaphysics of species, we see that species are the most particular terminal taxa in a clade, and that they are “defined” in terms of the particular synapomorphies, or evolved characters, that are causally responsible for keeping the lineages that organisms form distinct from one another. In this way, we can remain within the generative conception of species that has been in play for over two millennia, and yet avoid the pitfalls of prior attempts to find a universal conception of species.

Scientists and philosophers routinely talk about phenomena, and the ways in which they relate to explanation, theory and practice in science. However, there are very few definitions of the term, which is often used synonymously with "data'', "model'' and in older literature, "hypothesis''. In this paper I will attempt to clarify how phenomena are recognized, categorized and the role they play in scientific epistemology. I conclude that phenomena are not necessarily theory-based commitments, but that they are what explanations are called (...) to account for, which are not presently explained. (shrink)

The ninth edition of Media Ethics: Issues and Cases has been updated to reflect the most pressing ethical issues in media.

In this essay, I first evaluate the conceptual analysis of human rights by Wilfried Hinsch and Markus Stepanians. Next I criticize Allen Buchanan’s claim that Rawls did not address basic human interests/capabilities theories of human nature. I argue Buchanan is doubly mistaken when he claims that John Rawls sought to avoid such theories because they are comprehensive doctrines. Then I evaluate David Reidy’s defense of Rawls, while questioning his efforts to show how Rawls’s list of human rights could be expanded. (...) Finally, I accept James Nickel’s argument that Rawls has tied human rights too closely to intervention on their behalf. However, I reject his, and by implication Rawls’s, refusal to accept a two-tiered approach to human rights. (shrink)

Debates over adaptationism can be clarified and partially resolved by careful consideration of the ‘grain’ at which evolutionary processes are described. The framework of ‘adaptive landscapes’ can be used to illustrate and facilitate this investigation. We argue that natural selection may have special status at an intermediate grain of analysis of evolutionary processes. The cases of sickle-cell disease and genomic imprinting are used as case studies.

The biological species (biospecies) concept applies only to sexually reproducing species, which means that until sexual reproduction evolved, there were no biospecies. On the universal tree of life, biospecies concepts therefore apply only to a relatively small number of clades, notably plants andanimals. I argue that it is useful to treat the various ways of being a species (species modes) as traits of clades. By extension from biospecies to the other concepts intended to capture the natural realities of what keeps (...) taxa distinct, we can treat other modes as traits also, and so come to understand that theplurality of species concepts reflects the biological realities of monophyletic groups.We should expect that specialists in different organisms will tend to favour those concepts that best represent the intrinsic mechanisms that keep taxa distinct in their clades. I will address the question whether modes ofreproduction such as asexual and sexual reproduction are natural classes, given that they are paraphyletic in most clades. (shrink)
