Species concepts for bacteria and other microbes are contentious, because they are often asexual. There is a Problem of Homogeneity: every mutation in an asexual lineage forms a new strain, of which all descendents are clones until a new mutation occurs. We should expect that asexual organisms would form a smear or continuum. What causes the internal homogeneity of asexual lineages, if they are in fact homogeneous? Is there a natural “species concept” for “microbes”? Two main concepts devised for metazoans (...) and metaphytes have been applied to bacteria. One is the Recombination Concept, a revised form of the Biological Species Concept in which the homogenizing mechanism is the sharing of genome fragments, somewhat akin to sexual recombination. The other is the Ecological Species Concept, in which the ecological niche is that which maintains lineages as cohesive. In this paper I will discuss these two concepts, and offer an underlying model that conjoins them, and consider the implications for species concepts in general. In short, my argument is that asexual species are instances of the most primitive and underived notion of species, which I will call “quasispecies”, following Eigen, and that sexual species are merely one derived kind of species. Moreover, I will argue that there is a continuum of recombination from simple viral models in which each strain is a clone, through to obligate recombination of 50% of the parents’ genome, and that consequently there is no sharp division between “microbial” and more familiar species.

Democratic theorists often place deliberative innovations such as citizen's panels, consensus conferences, planning cells, and deliberative polls at the center of their hopes for deliberative democratization. In light of experience to date, the authors chart the ways in which such mini-publics may have an impact in the “macro” world of politics. Impact may come in the form of actually making policy, being taken up in the policy process, informing public debates, market-testing of proposals, legitimation of public policies, building confidence and (...) constituencies for policies, popular oversight, and resisting co-option. Exposing problems and failures is all too easy. The authors highlight cases of success on each of these dimensions. (shrink)

The construct of locus of control of reinforcement has generated thousands of studies since its introduction as a psychological concept by Julian Rotter. Although evidence indicates its importance for a wide range of outcomes, comparatively little research has been directed toward identification of potential developmental antecedents of internal/external expectancies. A previous review of antecedent findings called for more research to be completed, particularly using observational and/or longitudinal methodologies. The current paper summarizes and evaluates antecedent research published in the intervening years (...) since Carton and Nowicki’s review. Results largely were consistent with expectations based on Rotter’s social learning theory, although there is still a need for researchers to use observational, rather than self-report methodologies, and to include data from non-western cultures.

I sin udmærkede kommentar til vores artikel «En etisk diskussion af screening for kræftsygdomme» beskriver Geir Hoff den udtalte mangel på evidens vedrørende nytteværdien af screeningsprogrammer for kræftsygdomme baseret på randomiserede studier. Ydermere fremhæver Geir Hoff misforholdet mellem den manglende evidens ved screening og de strenge krav, der er til evidensen i den farmaceutiske industri. Dette er en velkommen kritik, pga. en udtalt ukritisk og uvidenskabelig tilgang til anvendelse af screening for denne eller hin sygdom eller risikofaktor.

Johann Friedrich Blumenbach has been called ‘The Father of Physical Anthropology’ because of his pioneering publications describing human racial variation. He proposed a racial typology consisting of five ‘major varieties/races’ of humanity. Since the 1990s, Londa Schiebinger and other Anglophone scholars have argued that Blumenbach’s writings on race show evidence that he was significantly influenced by nineteenth-century race supremacist beliefs which held Europeans/caucasians to be the highest ranked and most beautiful race. However, these modern authors relied largely on Thomas Bendyshe’s (...) 1865 English translations of Blumenbach’s Latin and German texts. As documented herein, Bendyshe’s publication includes numerous translation errors which form a pattern indicating that he employed two translators. The first translator was consistent with five earlier English translations. The second translator was not consistent with the earlier translators. This second translator also used English terms that denigrated extra-Europeans while adulating Europeans. Furthermore, Bendyshe’s1865 translation regularly used the term ‘beauty’ to translate different Latin words that Blumenbach used to express his nuanced view of aesthetics and structural symmetry. Given the inconsistency and errors in Bendyshe’s 1865 translations, they should not be unquestionably accepted as an accurate reflection of Blumenbach’s views. (shrink)

In Amartya Sen’s The Idea of Justice, democracy is necessary for the reconciliation of plural justice claims. Sen’s treatment of democracy is however incomplete and inadequate: democracy is under-specified, there are unrecognized difficulties in any context featuring deep moral disagreement or deep division and a conceptualization of public reason in the singular erodes his pluralism. These faults undermine Sen’s account of justice. Developments in the theory of deliberative democracy can be deployed to remedy these deficiencies. This deployment points to a (...) deliberative system encompassing those affected by collective decisions, with places for non-partisan forums and discursive representatives, conditionally open to multiple forms of communication, and geared to the production of workable agreements under normative and discursive meta-consensus. Democracy does not guarantee justice, but in a plural world it is essential to the pursuit of justice. (shrink)

People often have beliefs that are widely regarded as silly by the experts or by the general population. This leads us to ask why believers believe silly things if they are widely thought to be silly, and then why believers believe the specific things they do. I propose that silly beliefs function as in-group and out-group tribal markers. Such markers act as an honest costly signal; honest and costly because such beliefs are hard to fake. Then I offer a developmentalist (...) account of belief formation, in which beliefs are seen to be the result of a process of acquiring beliefs as cheaply and effectively as possible, leading to a reluctance to abandon early core beliefs later in life. Then I consider whether beliefs even can form a unified worldview, and ask how conversion occurs within the developmental characterization I propose. Finally, I consider how this may play out in terms of crises of faith. (shrink)

We consider McCarthy's notions of predicate circumscription and formula circumscription. We show that the decision problems “does θ have a countably infinite minimal model” and “does φ hold in every countably infinite minimal model of θ” are complete Σ 1 2 and complete π 1 2 over the integers, for both forms of circumscription. The set of structures definable as first order definable subsets of countably infinite minimal models is the set of structures which are Δ 1 2 over the (...) integers, for both forms of circumscription. Thus, restricted to countably infinite structures, predicate and formula circumscription define the same sets and have equally difficult decision problems. With general formula circumscription we can define several infinite cardinals, so the decidability problems are dependent upon the axioms of set theory. (shrink)

Tanner uses Kierkegaard's thought, in particular his theory of anxiety, to enrich a bold new reading of Milton's Paradise Lost. He argues that for Milton and Kierkegaard, the path to sin and to salvation lies through anxiety, and that both writers include anxiety within the compass of paradise. The first half of the book explores anxiety in Eden before the Fall, original sin, the aetiology of evil, and prelapsarian knowledge. The second half examines anxiety after the Fall, offering original insights (...) into such issues as the demonic personality, remorse, despair, and faith. (shrink)

Contending discourses underlie many of the worlds most intractable conflicts, producing misery and violence. This is especially true in the post-9/11 world. However, contending discourses can also open the way to greater dialogue in global civil society and across states and international organizations. This possibility holds even for the most murderous sorts of conflicts in deeply divided societies. In this timely and original book, John Dryzek examines major contemporary conflicts in terms of clashing discourses. Topics covered include the alleged (...) clash of civilizations; societies divided by ethnicity, nationality, or religion; economic globalization versus resistance; plus an in-depth discussion of the 'war on terror'. Dryzek concludes by highlighting the limitations of current neoconservative and cosmopolitan approaches, arguing that only deliberative global politics offers unprecedented new possibilities for democratic engagement in the international system. This book will be of interest to students and scholars of international relations, politics, philosophy, and sociology. (shrink)

This paper relates to Lyotard's philosophy of a différend. The paper has a dual purpose. The first is to explain what is meant by a différend and also a petit différend. The intention here is to preserve both the intrinsic validity and ethico-political value of the concept in cases where its legitimacy might easily be denied. This feeds into the second and main purpose of the paper, which is to testify to a petit différend in quality of care, so that (...) care may be taken in how the term ‘quality of care’ is actually used. It is here that the implications of a petit différend in quality of care are opened up from the perspective of cared-for and professional carers, respectively. It will be shown that the idea of quality of care is open to multiple interpretations, and therefore to disputes that judgement cannot resolve to the satisfaction of all parties. (shrink)

Compiled in the second century B.C.E, the _Huainanzi_ clarifies a crucial period in the development of Chinese conceptions of the cosmos, human nature, and the social order. Outlining "all that a modern monarch needs to know," the text emphasizes rigorous self-cultivation and mental discipline, attributing successful rule to a balance of broad knowledge, diligent application, and penetrating wisdom. In 2010, the editors of this volume completed the first complete English-language translation of the _Huainanzi_, opening exciting new pathways in the study (...) of philosophy, Asian studies, political science, and Asian literature. This abridgement contains essential selections from each of the _Huainanzi_'s twenty-one chapters and adds a new introduction and chapter descriptions. The text represents a remarkable synthesis of Daoist classics, such as the _Laozi_ and the _Zhuangzi_; works associated with the Confucian tradition, such as the _Changes_, the _Odes_, and the _Documents_; and a range of other foundational philosophical and literary works, from the _Mozi_ to the _Hanfeizi_. The abridgement preserves the _Huainanzi_'s special rhetorical features, such as its parallel prose, verse, and unique compositional techniques. For decades, Western scholars overlooked the _Huainanzi'_s sophisticated structure, creative content, and rich historical value, yet all that changed with the translation of the full text. Designed for classroom use and general readers, _The Essential Huainanzi_ continues to increase awareness of this brilliant work and change our understanding of early Chinese history. (shrink)

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.
