Human nature has always been a foundational issue for philosophy. What does it mean to have a human nature? Is the concept the relic of a bygone age? What is the use of such a concept? What are the epistemic and ontological commitments people make when they use the concept? In What’s Left of Human Nature? Maria Kronfeldner offers a philosophical account of human nature that defends the concept against contemporary criticism. In particular, she takes on challenges related (...) to social misuse of the concept that dehumanizes those regarded as lacking human nature (the dehumanization challenge); the conflict between Darwinian thinking and essentialist concepts of human nature (the Darwinian challenge); and the consensus that evolution, heredity, and ontogenetic development results from nurture and nature. After answering each of these challenges, Kronfeldner presents a revisionist account of human nature that minimizes dehumanization and does not fall back on outdated biological ideas. Her account is post-essentialist because it eliminates the concept of an essence of being human; pluralist in that it argues that there are different things in the world that correspond to three different post-essentialist concepts of human nature; and interactive because it understands nature and nurture as interacting at the developmental, epigenetic, and evolutionary levels. On the basis of this, she introduces a dialectical concept of an ever-changing and “looping” human nature. Finally, noting the essentially contested character of the concept and the ambiguity and redundancy of the terminology, she wonders if we should simply eliminate the term “human nature” altogether.

Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative hypothesis formation is guided (...) rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate?acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate?acquired distinction is under attack (...) in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment are taken into account, then the innate?acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature?nurture debates. (shrink)

Continuing Franz Boas' work to establish anthropology as an academic discipline in the US at the turn of the twentieth century, Alfred L. Kroeber re-defined culture as a phenomenon sui generis. To achieve this he asked geneticists to enter into a coalition against hereditarian thoughts prevalent at that time in the US. The goal was to create space for anthropology as a separate discipline within academia, distinct from other disciplines. To this end he crossed the boundary separating anthropology from biology (...) in order to secure the boundary. His notion of culture, closely bound to the concept of heredity, saw it as independent of biological heredity (culture as superorganic) but at the same time as a heredity of another sort. The paper intends to summarise the shifting boundaries of anthropology at the beginning of the twentieth century, and to present Kroeber?s ideas on culture, with a focus on how the changing landscape of concepts of heredity influenced his views. The historical case serves to illustrate two general conclusions: that the concept of culture played and plays different roles in explaining human existence; that genetics and the concept of Weismannian hard inheritance did not have an unambiguous unidirectional historical effect on the vogue for hereditarianism at that time; on the contrary, it helped to establish culture in Kroeber's sense, culture as independent of heredity.

The article addresses the question whether culture evolves in a Lamarckian manner. I highlight three central aspects of a Lamarckian concept of evolution: the inheritance of acquired characteristics, the transformational pattern of evolution, and the concept of directed changes. A clear exposition of these aspects shows that a system can be a Darwinian variational system instead of a Lamarckian transformational one, even if it is based on inheritance of acquired characteristics and/or on Lamarckian directed changes. On this basis, I apply (...) the three aspects to culture. Taking for granted that culture is a variational system, based on selection processes, I discuss in detail the senses in which cultural inheritance can be said to be Lamarckian and in which sense problem solving, a major factor in cultural change, leads to directed variation.

Charles Darwin und seine Erben wendeten die Theorie der Evolution biologischer Arten auch auf Kultur an. Kultur evolviere wie die Natur auf Darwinistische Weise. Die sog. Memtheorie, vertreten von verschiedenen Autoren auf der Basis des Darwinistischen Genselektionismus, ist eine Spielart einer solchen analogen Anwendung. Dieser Artikel kritisiert drei zentrale Aussagen der Memtheorie: (i) dass es Einheiten der Kultur – Meme – gibt, die analog zu Genen zu verstehen sind, (ii) dass Meme, in Analogie zu Genen, Replikatoren sind, und (iii) dass (...) Meme als Einheiten der kulturellen Selektion auf die gleiche Art wie Gene 'egoistisch' sein können. Nach einer Einführung in die Memtheorie in Teil 1, werden diese drei Thesen in Teil 2 als entweder falsch oder trivial entlarvt. Dieser kritische Teil soll vor allem zeigen, dass die Memtheorie keine 'gefährliche Idee' ist, die das bisher in den Geistes- Kultur- und Sozialwissenschaften tradierte Verständnis von Geist und Kultur herausfordern kann. Im Gegenteil, im besten Fall re-formuliert die Memtheorie lediglich Bekanntes in evolutionärer Sprache und ist in diesem Sinne trivial. In Teil 3 wird die Perspektive gewechselt: Nicht mehr der Gehalt, sondern die Funktion der Memtheorie, v.a. im Kontext interdisziplinärer Verständigung, soll betrachtet werden. Denn trotz der Kritik der drei Kernthesen kann die Memtheorie eine kommunikative und somit produktive Rolle zwischen den 'zwei Kulturen' der Wissenschaften spielen. (shrink)

In the face of causal complexity, scientists reconstitute phenomena in order to arrive at a more simplified and partial picture that ignores most of the 'bigger picture.' This paper will distinguish between two modes of reconstituting phenomena: one moving down to a level of greater decomposition (toward organizational parts of the original phenomenon), and one moving up to a level of greater abstraction (toward different differences regarding the phenomenon). The first aim of the paper is to illustrate that phenomena are (...) moving targets, i.e., they are not fixed once and for all, but are adapted, if necessary, on the basis of the preferred perspective adopted for pragmatic reasons. The second aim is to analyze in detail the second mode of reconstituting phenomena. This includes an exposition of the kind of pragmatic-pluralistic picture resulting from the fact that phenomena are reconstituted by a move up to a level of greater abstraction. (shrink)

This paper addresses whether the often-bemoaned loss of unity of knowledge about humans, which results from the disciplinary fragmentation of science, is something to be overcome. The fragmentation of being human rests on a couple of distinctions, such as the nature-culture divide. Since antiquity the distinction between nature (roughly, what we inherit biologically) and culture (roughly, what is acquired by social interaction) has been a commonplace in science and society. Recently, the nature/culture divide has come under attack in various ways, (...) in philosophy as well as in cultural anthropology. Regarding the latter, for instance, the divide was quintessential in its beginnings as an academic dis-cipline, when Alfred L. Kroeber, one of the first professional anthropologists in the US, rallied for (what I call) the right to ignore—in his case, human nature—by adopting a separationist epistemic stance. A separationist stance will be understood as an epistemic research heuristic that defends the right to ignore a specif-ic phenomenon (e.g., human nature) or a specific causal factor in an explanation typical for a disciplinary field. I will use Kroeber’s case as an example for making a general point against a bias towards integration (synthesis bias, as I call it) that is exemplified, for instance, by defenders of evolutionary psychology. I will claim that, in principle, a separationist stance is as good as an integrationist stance since both can be equally fruitful. With this argument from fruitful sepa-ration in place, not just the separationist stance but also the nature/culture di-vide can be defended against its critics. (shrink)

Academic freedom has often been defended in a progressivist manner: without academic freedom, creativity would be in peril, and with it the advancement of knowledge, i.e. the epistemic progress in science. In this paper, I want to critically discuss the limits of such a progressivist defense of academic freedom, also known under the label ‘argument from truth.’ The critique is offered, however, with a constructive goal in mind, namely to offer an alternative account that connects creativity and academic freedom in (...) a way that goes beyond mere reference to epistemic progress and involves reference to the freedom to think independently as the freedom we mean when we point to creativity and when we point to academic freedom. The resulting causal independence account is not only epistemologically stronger than a progressivist account, it also allows to counter the curbing of academic freedom in the name of progress. The latter becomes key, for instance, when authoritarian political regimes limit or negate academic freedom with reference to an epistemic progress suitably defined for that regime. (shrink)

Theories of cultural evolution rest on the assumption that cultural inheritance is distinct from biological inheritance. Cultural and biological inheritance are two separate so-called channels of inheritance, two sub-systems of the sum total of developmental resources traveling in distinct ways between individual agents. This paper asks: what justifies this assumption? In reply, a philosophical account is offered that points at three related but distinct criteria that (taken together) make the distinction between cultural and biological inheritance not only precise but also (...) justify it as real, i.e. as ontologically adequate. These three criteria are: (a) the autonomy of cultural change, (b) the near-decomposability of culture, and (c) differences in temporal order between cultural and biological inheritance. (shrink)

In diesem Beitrag geht es um die Frage, ob wir aus fiktionalen literarischen Werken etwas lernen können. Können fiktionale literarische Werke uns Wissen vermitteln? Wenn ja, wie ist das möglich, und welche Art von Wissen vermitteln uns fiktionale Werke? Es wird argumentiert, dass fiktionale literarische Werke in der Tat Wissen vermitteln können, und zwar, unter anderem, propositionales Wissen über die “wirkliche Welt”.

The topic of this paper is the relationship between value facts (e.g., that this is good) and value experiences (e.g., appreciation). Its aim is, first, to give a concise account of the value theories of some important early phenomenologists (Franz Brentano, Christian von Ehrenfels, Alexius Meinong), second, to show that they raise questions and put forward arguments that are still worthy of note, and, third, to critically assess these arguments. Among others, the following questions are discussed: Can past and other (...) nonexistent objects have value? Are value experiences feelings or rather desires? Are value properties exemplified by “immanent objects” only? (shrink)

In diesem Beitrag werden drei Thesen verteidigt: 1. Interpretationen literarischer Werke (im Sinne von Aussagen über die Bedeutung literarischer Werke) können richtig oder falsch sein. 2. Werke haben eine objektive Bedeutung, unabhängig von Interpretationen. 3. Die Bedeutung eines Werks wird wesentlich durch die kommunikativen Absichten der Autorin determiniert. Die Position, dass Werk- und Textbedeutungen durch tatsächliche Autorabsichten des echten Autors konstituiert werden – die Position des aktualen Intentionalismus – wird gegen eine Reihe von Einwänden und konkurrierenden Theorien verteidigt, nämlich gegen (...) den Konstruktivismus (»Werke und Texte haben keinerlei Bedeutung unabhängig von einer Interpretation«), den Konventionalismus (»Die Werk- und Textbedeutung ist ausschließlich durch linguistische Konventionen determiniert«), den Kontextualismus (»Die Werk- und Textbedeutung ist ausschließlich durch den Äußerungskontext determiniert«) und den hypothetischen Intentionalismus (»Die Bedeutung eines Werks bzw. Textes ist identisch mit dem, was ein intendiertes bzw. ideales Publikum für die Bedeutung des Werks bzw. Textes halten würde«). (shrink)

Thinking of problems of aesthetics has a long and strong tradition in Austrian Philosophy. It starts with Bernard Bolzano (1781-1848); it is famously represented by the critic and musicologist Eduard Hanslick (1825-1904); and it is continued within the school of Alexius Meinong (1853-1920), in particular by Christian von Ehrenfels (1859-1932) and Stephan Witasek (1870-1915). Nowadays the aesthetic writings of Bolzano, Ehrenfels, and Witasek are hardly known, particularly not in the Anglo-Saxon world. Austrian aesthetics is surely less known than Austrian contributions (...) to other philosophical disciplines, like ontology, epistemology or philosophy of science. One of the aims of this paper is to show that this is both regrettable and unjustified for the following reasons: Austrian aestheticians have dealt with a number of problems (mainly concerning the foundations of aesthetics) that are salient until today; in terms of subtlety and depth as well as exactness and originality, in general, they easily stand comparison with today's analytic aesthetics; and many of there views and arguments are still worthy of consideration. In this paper, the focus is on a number of hardly known Austrian contributions to aesthetics. These contributions concern the following, partly interrelated, central problems of philosophical aesthetics: i. The problem of the definition of beauty (What is beauty? What does it mean to say of an object that it is beautiful?) ii. The problem of the ontological status of works of art (What kinds of objects are works of art?) iii. The problem of the objectivity of aesthetic values (Do we claim objective validity for aesthetic value judgements, and if so, is this claim justified?) The answers of Bolzano, Meinong, Witasek and Ehrenfels to these questions will be considered. (shrink)

Citrate, an organic trivalent anion, is a major substrate for generation of energy in most cells. It is produced in mitochondria and used either in the Krebs' cycle or released into cytoplasm through a specific mitochondrial carriers. Citrate can also be taken up from blood through different plasma membrane transporters. In the cytoplasm, citrate can be used ultimately for fatty acid synthesis, which is increased in cancer cells. Here, we review the ways in which citrate can be transported and discuss (...) the changes in transport and metabolism that occur in cancer cells. The primary focus is on the prostate gland, which is known to produce and release large amounts of citrate during its normal secretory function. The significant changes that occur in citrate‐related metabolism and transport in prostate cancer are the second focus. This review strives to relate these mechanisms to molecular biology on the one hand and to clinical applications on the other. (shrink)

The concept of “critical science literacy” advanced by Susanna Priest is significant to how citizens approach scientific knowledge, but the concept is also relevant to undergraduate students majoring in the sciences, who are not necessarily becoming “critically literate” in their own disciplines. That is, future scientists are not learning how arguments are structured, meaning is made, and facts are agreed upon—specifically through communicative practices—both within and outside of the scientific community. This gap in the curriculum can be addressed through collaborative (...) efforts between rhetoricians and sociologists of science. Drawing from three major disciplinary traditions—writing studies, the rhetoric of science, and science communication—this article posits that a pedagogical intervention is necessary to improve science communication with nonexpert publics. A science writing and communication course that is grounded in the rhetoric of science and that also has sociological, philosophical, and historical components can provide science students with a critical awareness of how their discipline operates in society and teach them how to become more responsible and effective communicators.

States of affairs raise, among others, the following questions: What kind of entity are they (if there are any)? Are they contingent, causally efficacious, spatio-temporal and perceivable entities, or are they abstract objects? What are their constituents and their identity conditions? What are the functions that states of affairs are able to fulfil in a viable theory, and which problems and prima facie counterintuitive consequences arise out of an ontological commitment to them? Are there merely possible (non-actual, non-obtaining) states of (...) affairs? Are there molecular (i.e., negative, conjunctive, disjunctive etc.) states of affairs? Are there modal and tensed states of affairs? (shrink)

Thema der Arbeit ist der ontologische Status von Werken sowie die Beziehung zwischen Werken einerseits und Aufführungen, Manuskripten, Partituren, Schallplatten, Gemälden, Gebäuden, Drucken etc. andererseits. Es wird angeknüpft an den phänomenologischen Ansatz von Roman Ingarden (aber auch an den von Alexius Meinung). Diese Ansätze werden unter Verwendung moderner logischer Hilfsmittel weiterentwickelt und, wo notwendig, revidiert. Im ersten Kapitel wird ausführlich begründet, warum Werke (und zwar Werke aller Gattungen) abstrakte, typenartige Gegenstände sein müssen, die in konkreten Einzeldingen (z. B. Aufführungen) realisiert (...) sein können, jedoch von diesen Realisierungen in ihrer Existenz nicht abhängig sind. Diese These ist im weiteren Verlauf der Arbeit eine nicht mehr hinterfragte Grundvoraussetzung. Im zweiten Kapitel werden die formalen Grundlagen einer Typenontologie des Werks entwickelt. Zwei Hauptfragen stehen dabei im Vordergrund: (a) Wie kann ein Werk (also ein abstrakter Gegenstand) sinnliche Eigenschaften (z. B. Klangeigenschaften, Farbeigenschaften) haben? (b) Was macht einen Gegenstand zu einer Realisierung eines Werks? Welche Bedingungen müssen erfüllt sein, damit etwas eine Realisierung eines gegebenen Werks ist? Neben dem Begriff des Werks beruht die in dieser Arbeit entwickelte Theorie auf drei weiteren Grundbegriffen: Realisierungen, Konkretisierungen und Aktualisierungen. Realisierungen sind jene Gegenstände, in denen Werke realisiert sind. Konkretisierungen sind abstrakte Gegenstände, die durch "Vervollständigung" aus Werken hervorgehen. Sie sind immer noch unvollständig bestimmt, aber vollständiger bestimmt als die Werke, deren Konkretisierungen sie sind. Beispiele für Konkretisierungen sind Inszenierungen im Theater oder musikalische Interpretationen. Aktualisierungen sind die intentionalen Korrelate von Rezeptionsvorgängen. Sie entstehen im Verlauf der Rezeption eines Werks und werden von den Rezipienten erzeugt. Ein und dasselbe Werk kann auf verschiedene Weisen aktualisiert werden (z. B.: ein Musikstück kann auf verschiedene Weisen "gehört" werden). In eigenen Kapiteln werden Probleme der Mereologie, der Identität, des Darstellens und der Beziehung zwischen dem darstellenden Werk und dem Dargestellten erörtert. (shrink)

The aim of this paper is an ontological clarification of the concept of artefact. The following questions are addressed: 1. Do artefacts constitute an ontological category of objects in its own right, and if so, how could this category be characterized? 2. How do artefacts come into existence? 3. What kind of artefacts are there, and in which relations do they stand to each other? It is argued that artefacts are characterized essentially through their genesis and that they owe their (...) existence to mental acts of a particular kind, which I call “acts of creation”. It is maintained that there are not only concrete, material artefacts, but also abstract artefacts, that is, artefacts that cannot be perceived through the senses and are not located in space. Furthermore, it shall be claimed that in a sense those abstract artefacts are even primary to the concrete, material artefacts. (shrink)

The general topic of this paper is the ontological commitment to so-called "fictitious objects", that is, things and characters of fictional stories, like Sherlock Holmes and Pegasus. Discourse about fiction seems to entail an ontological commitment to fictitious entities, a commitment that is often deemed inconsistent with empirical facts. For instance, "Pegasus is a flying horse" seems to entail "There are flying horses" as well as "Pegasus exists" (according to some widely accepted logical principles). I discuss two solutions that have (...) been proposed in the literature. The first one amounts to rejecting sentences like "Pegasus is a flying horse" as false, at least if they are taken at face value. This solution is called the "story operator strategy". It consists in paraphrasing sentences like "Pegasus is a flying horse" by means of the expression "according to a story" such that they are interpreted as an elliptic formulation of, e.g., "According to a story, Pegasus is a flying horse". I spell out the difficulties of the story operator strategy and opt for a realist ontology of fiction. A novel interpretation of the story operator "according to a story" is given, which is not only consistent with but even sheds new light on such a realist ontology. In particular, it is shown how the story operator can be used as a tool to introduce the so-called "modes of predication distinction" (which is an essential ingredient of many realist ontologies of fiction) in a commonsensical way.

Terence Horgan's "contextual semantics" is supposed to be a means to avoid unwanted ontological commitments, in particular commitments to non-physical objects, such as institutions, theories and symphonies. The core of contextual semantics is the claim that truth is correct assertibility, and that there are various standards of correct assertibility, the standards of "referential semantics" being only one among others. I am investigating the notions of correct assertibility,assertibility norms and indirect reference. I argue that closer inspection reveals that contextual semantics ultimately (...) amounts – contra Horgan's intentions – to a paraphrase strategy. I defend an ontological commitment to theories and symphonies. (shrink)

Eine ausgearbeitete Kunstontologie findet sich bei Ehrenfels nicht, wohl aber Bausteine zu einer solchen. Diese herauszuarbeiten ist das Anliegen des vorliegenden Beitrags. Dabei geht es um die Frage nach dem ontologischen Status von Kunstwerken, um mögliche kategoriale Einteilungen derselben, um Bestandteile und Identitätsbedingungen. Ehrenfels vertritt die Auffassung, dass nicht materielle Entitäten, sondern „Vorstellungskomplexe“ Träger ästhetischer Eigenschaften sind. Ich argumentiere, dass Ehrenfels die Auffassung zugeschrieben werden kann, dass Kunstwerke nicht mit materiellen Gegenständen, sondern mit Vorstellungskomplexen zu identifizieren sind. Im Weiteren wird (...) die Frage diskutiert, ob die Vorstellungskomplexe als mentale Entitäten im engeren Sinn aufzufassen sind (d. h. als Entitäten, die in jedem Moment ihrer Existenz von Bewusstseinsvorgängen ontologisch abhängig sind) oder ob sie von Bewusstseinsvorgängen unabhängige Existenz haben können. Zur Beantwortung dieser Frage wird ein wenig beachteter Text zur Gestalttheorie herangezogen, der eine überraschende Antwort nahe legt. Was die Frage nach den Bestandteilen betrifft, lässt sich aus Ehrenfels’ Schriften die Auffassung extrahieren, dass Kunstwerke aus Gestalten bestehen, die entweder durch sinnliche Qualitäten oder durch Psychisches fundiert sein können. Ich zeige zudem, dass Ehrenfels eine differenzierte Auffassung bezüglich der Identitätsbedingungen von Kunstwerken vertritt: In erster Linie sind die konstituierenden Gestalten identitätsrelevant, doch es können auch Kontexte und Funktionen eine Rolle spielen.

As interest in women’s roles in agriculture increases, research on women livestock-keepers remains limited. Advances in feminist scholarship highlight farming women’s dual roles in agricultural production and biological and socio-cultural reproduction, including women’s uncompensated labor in child-bearing, child-rearing and home-making. To expand knowledge about women pastoralists’ lived experiences, we conducted life-history interviews with 25 herder women in two regions of Mongolia, following-up with participatory workshops in each region. As mothering and carework emerged as key themes, we drew on feminist care (...) ethics and the anthropology of mothering and motherhood to analyze interview data and co-interpret results with workshop participants. Our findings reveal three caring conflicts experienced by Mongolian herder women: between caring for _nutag_ (homeland) and caring for herds, between caring for herds and caring for children, and between caring for family, herd and _nutag_ and caring for self. These conflicts highlight contradictions between normative Mongolian motherhood as depicted in cultural images and narratives, and the lived reality of herder mothers, and between public valorization of and incentives for motherhood and the lack of sufficient public support for mothers and carework in rural Mongolia. Unmet needs for care, resulting risks to maternal and child health, and the extraordinary workload associated with mothers’ multiple caring tasks likely contribute to rural–urban migration and increasing masculinization of the Mongolian countryside. Although Mongolian culture frames mothers as leaders who unify their communities through their wisdom, many herder-mothers today live isolated lives where their multiple caring responsibilities preclude active participation in community development and governance.

The book examines how Darwinism has been used to explain novelty and change in culture through the Darwinian approach to creativity and the theory of memes. The first claims that creativity is based on a Darwinian process of blind variation and selection, while the latter claims that culture is based on and explained by units - memes - that are similar to genes. Both theories try to describe and explain mind and culture by applying Darwinism by way of analogies. (...) class='Hi'>Kronfeldner shows that the analogies involved in these theories lead to claims that give either wrong or at least no new descriptions or explanations of the phenomena at issue. Whereas the two approaches are usually defended or criticized on the basis that they are dangerous for our vision of ourselves, this book takes a different perspective: it questions the acuteness of these approaches. Darwinian theory is not like a dangerous wolf, hunting for our self image. Far from it, in the case of the two analogical applications addressed in this book, Darwinian theory is shown to behave more like a disoriented sheep in wolf's clothing. - A revised and much shortened version of a dissertation (2007, Darwinism, Memes and Creativity: A Critique of Analogical Reasoning from Nature to Culture).

In this Chapter, Maria Kronfeldner discusses whether psychological essentialism is a necessary part of dehumanization. This involves different elements of essentialism, and a narrow and a broad way of conceptualizing psychological essentialism, the first akin to natural kind thinking, the second based on entitativity. She first presents authors that have connected essentialism with dehumanization. She then introduces the error theory of psychological essentialism regarding the category of the human, and distinguishes different elements of psychological essentialism. On that basis, (...) Kronfeldner connects historical, socio-psychological, and philosophical insights in order to show that although essentialism can act as a catalyst for dehumanization, it is not necessary for it. Examples relate to dehumanization in the context of colonialism and evolutionary thinking, to the history of dehumanizing women from Aristotle to 19th-century craniology, and to contemporary self-dehumanization and ‘lesser mind’ attribution.

The Hoffmann reflex (H-wave) is produced by alpha-motoneuron activation in the spinal cord. A feature of this electromyography response is that it exhibits fluctuations in amplitude even during repetitive stimulation with the same intensity of current. We herein explore the hypothesis that physical training induces plastic changes in the motor system. Such changes are evaluated with the fractal dimension (FD) analysis of the H-wave amplitude-fluctuations (H-wave FD) and the cross-covariance (CCV) between the bilateral H-wave amplitudes. The aim of this study (...) was to compare the H-wave FD as well as the CCV before and after track training in sedentary individuals and athletes. The training modality in all subjects consisted of running three times per week (for 13 weeks) in a concrete road of 5 km. Given the different physical condition of sedentary vs. athletes, the running time between sedentary and athletes was different. After training, the FD was significantly increased in sedentary individuals but significantly reduced in athletes, although there were no changes in spinal excitability in either group of subjects. Moreover, the CCV between bilateral H-waves exhibited a significant increase in athletes but not in sedentary individuals. These differential changes in the FD and CCV indicate that the plastic changes in the complexity of the H-wave amplitude fluctuations as well as the synaptic inputs to the Ia-motoneuron systems of both legs were correlated to the previous fitness history of the subjects. Furthermore, these findings demonstrate that the FD and CCV can be employed as indexes to study plastic changes in the human motor system. (shrink)
