Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species (...) concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be used (...) by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

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.

People should take immediate action to prevent climate harms. Although intuitive, this claim faces two important problems. First, no individual can avert a climate harm on their own. Second, too few people are typically willing to contribute. In response, I point out that individuals can sometimes help prevent harm to the climate, and I argue that they should take preventive action when the prospect of success is good enough. Furthermore, when too few are willing to contribute, an individual may be (...) required to activate others to increase their number. This serves to increase the prospect of success. Crucially, this prospect may be good enough well before enough people have become willing to engage. It follows that people should start saving the planet soon, if not immediately. (shrink)

Definition of the problem: In 1997, Percutaneous Transluminal Coronary Angioplasty (PTCA) was performed in 138.001 cases in Germany. The standard indications, single vessel disease and badly controlled angina, are more and more extended to multivessel disease with and without severe angina, unstable or preinfarction angina, and acute myocardial infarction (AMI) itself. Dilating asymptomatic stenoses of more than 70–80% is a widely used indication, intending prophylaxis of complete occlusion and AMI. Actually there is no generally accepted guideline for the different new (...) indications, conservative versus invasive treatment schedule. It is difficult for the patient to get appropriate information before his decision between mechanical procedures and conservative methods; authentic informed consent actually seems to be in a very bad position. In 1992 the working group called ”Arbeitsgemeinschaft leitender kardiologischer Krankenhausärzte (ALKK)” decided to start a registry of all PTCA procedures, in order to gain knowledge about the present status of PTCA in Germany. Up to March 1999, 198.608 PTCA are logged.Arguments: Each PTCA was included on an intention-to-treat basis. The registry succeeded in a nearly complete recording with 98,6% of all PTCA procedures complete on March 17th, 1999. 93,5% of stenosed and 72,2% of the total occluded vessels were successfully dilated. In 4.729 cases (2,63%) the PTCA caused severe complications. The overall in-hospital mortality was only 0,5%, if the procedures done for AMI were excluded (including AMI it was 1,1%). The calculation of complications should be an essential part of the patients informed consent.Conclusion: Complete recording of all PTCA procedures is feasible even on a nationwide basis. Some results of the registry, as the indication control and the complication rate may help to realize a better doctor-patient-conversation on risks and benefits of either concept. The trend of many CHD patients is ”modern”: It should be done what can be done (mechanically), with results at once. Although said somehow paternalistic, this point of view cannot be tolerated: Proper informed consent today includes the realistic alternative of modern medicaments, especially those with an aggressive cholesterol lowering potency.

In the famous opening sentence of The Eighteenth Brumaire, Marx notes that somewhere Hegel had written that great world-historical phenomena occur twice, neglecting to add, however, the first time as tragedy, the second as farce. Given what we now know of the heretofore hidden side of Bruno Rizzi, still another revision seems in order: sometimes such phenomena make yet a third appearance, this time as embarrassment, rank embarrassment. Indeed, Rizzi's name surfaced in three such sequential contexts. The first was in (...) the late 1930s when non-stalinist Marxists, primarily Trotskyists, were debating whether or not a “new class” had emerged in the Soviet Union. (shrink)

Plato: The Timaeus There is nothing easy about the Timaeus. Its length, limited dramatic discourse, and arid subject-matter make for a dense and menacing work. But make no mistake, it is a menacing work of great subtly and depth. Cosmology has traditionally received the bulk of scholarly attention. No less important, however, are the dialogue’s … Continue reading Plato: The Timaeus →.

The thrust of Berger's defense of capitalism and rejection of socialism appears in two 1981 articles in the Harvard Business Review by Podhoretz and Berger. The latter is the basis of chapter 9 in The Capitalist Revolution. Both pieces look like classified advertisements, offering the services of neoconservative intellectuals as the “new defenders of capitalism.” The 1980 election returns, Berger wrote, have shown that “the recent political isolation of business might be at an end, and with its passing American society (...) might come again to understand the value of its capitalist heritage.” Yet, Berger warned, the complete restoration of the legitimacy of the business community “will depend as much on successful competition over ideas as on successful performance in the market.”.

There is no single version of physicalism. There is no single argument for physicalism. There is, accordingly, no standard answer concerning the implications of physicalism for the causation of human action by mental states. This chapter begins by describing a preferred version of physicalism and its implications about the connection between subjects' mental states and what they do, and thereby for the determination and predictability of our actions. This serves as a precursor for a short discussion of the implications of (...) physicalism for the possibility of free action. The chapter also discusses an anomalous physicalism that holds it is a mistake in principle to identify the mental and the physical, in the sense of identifying mental and physical kinds. At first blush, this kind of physicalism might seem good news for those who worry about the implications of physicalism for freedom. However, it is shown that the good news is not that good.

Normative analysis of cognition-enhancing drugs frequently weighs the liberty interests of drug users against egalitarian values. Yet those who would refuse to engage in neuroenhancement may well find their liberty to do so limited in a society where such drugs are widespread. To the extent that unvarnished emotional responses are world-disclosive, neurocosmetics also threaten to foist faulty data upon all their users. This essay examines underappreciated liberty-based and epistemic rationales for regulating cognition-enhancing drugs.

De la composition musicale au design sonore" réunit différents textes pour la plupart déjà publiés, soit dans des revues, soit comme chapitres d'ouvrage ou actes de colloque sur le thème de la musique, progressivement repensée comme le design de sons. Rassemblés à l'occasion d'une Habilitation à Diriger les Recherches (2018), ces textes concernent la création musicale, sa relation à l'image et l'écriture des sons à un moment charnière - la révolution digitale de la fin du siècle dernier - qui posent (...) de nouveaux défis, tant du côté de la création, que de celui de la recherche et de leurs enseignements réciproques. D'une réflexion musicologique déjà orientée vers la question de la perception, ses travaux ont peu à peu porté sur les relations entre la musique et la technologie puis, via celle de la musique au cinéma et à l'accompagnement de l'image, l'auteur en est arrivé à la question du design sonore. Aux confins de la philosophie et des sciences de l'art, il s'interroge finalement sur les perspectives de formation des futurs acteurs de cette interdisciplinarité épistémologique. Peut-on être assurément chercheur simultanément non seulement dans sa pratique mais aussi sur sa pratique? Cette double posture est-elle épistémologiquement tenable et si oui à quelle condition? A supposer qu'elle le soit au plan existentiel, n'implique-t-elle pas une position de juge et partie, et donc un risque de biais cognitif, à tout le moins méthodologique? (shrink)

This work contrasts conservative or minimally mutilating revisions of empirical theories as they are identified in the presently dominant AGM model of formal belief revision and the structuralist program for the reconstruction of empirical theories. The aim is to make understandable why both approaches only partly succeed in substantially informing and formally restraining the issue. With respect to the rationality of minimal change, the overall result is negative. Readers with an interest in formal epistemology are provided with application cases, the (...) historically inclined reader is offered a systematic perspective. The discussion can largely be followed without a background in formal logic. (shrink)

According to Michael Rescorla’s recent defense of dialectical egalitarianism reasoned discourse lacks a foundational structure, but saves the foundational intuition that some propositions are basic. On this view, I may select the reasons forwarded in support of a claim according to their being accepted by particular communities/audiences. I discuss the epistemic risk of doing so, and clarify if Rescorla’s is an epistemic approach in disguise.

A proposal by Ferguson [2003, Argumentation 17, 335–346] for a fully monotonic argument form allowing for the expression of defeasible generalizations is critically examined and rejected as a general solution. It is argued that (i) his proposal reaches less than the default-logician’s solution allows, e.g., the monotonously derived conclusion is one-sided and itself not defeasible. (ii) when applied to a suitable example, his proposal derives the wrong conclusion. Unsuccessful remedies are discussed.
