Even today, a century after the publication of the “Origin of Species”, current zoological literature often reveals an insufficient grasp of the implications of the now generally accepted view that it is natural selection that confers direction on the evolutionary process.This is, in part, due to a reaction against oversimplified teleology and against Lamarckism. In rejecting Lamarck's thesis that the activities of an animal directly affect its hereditary characters it is frequently assumed that this implies that such activities are irrelevant (...) to the study of evolution. This is a non-sequitur, for activities may affect evolution not directly, through heredity, but indirectly, by influencing the direction of the selective forces impinging on the organism. Reasons are given for concluding that changes in habits and behaviour frequently precede structural change and, in fact, determine the direction of the latter.As an example of a concept which deserves a more evolutionary treatment than it commonly receives, the subject of neoteny is considered. It appears that failure to think in terms of the selective forces involved has frequently led to error. An analysis in functional terms is made of the theory that the chordates represent secondarily glorified sea-squirts and it is concluded that this idea is unlikely to be correct. The characteristics of man that are commonly considered to be neotenous are also discussed. It is concluded that a facile and unanalytical application of the label “neoteny” to many of the evolutionary changes involved has tended to obscure rather than to clarify their significance: the neotenous features of man are not those that have been of primary importance in human evolution, but are secondary to the acquisition of new characters which are not to be found in either the adult or the young stages of any other primate.Aujourd'hui, un siècle après l'apparition de l'Originedes Espèces, la conviction est presque générale que la sélection naturelle dirige le procès de l'évolution. Néanmoins, les publications zoologiques actuelles révèlent souvent une compréhension insuffisante de ce qui en résulte.Ceci doit en partie être considéré comme réaction contre une téléologie simpliste et contre le Lamarckisme. En rejetant la thèse de Lamarck, que les activités d'un animal ont une influence directe sur ses caractéristiques héréditaires, on admet fréquemment que de pareilles activités n'ont rien à voir avec l'étude le l'évolution. Cependant, une telle conclusion n'est pas justifiée, car les activités peuvent influer sur l'évolution non pas directement, par la voie de l'hérédité, mais indirectement en agissant sur la direction des forces sélectives que l'organisme rencontre. Des raisons ont été données qui mènent à conclure que des changements dans les habitudes et dans le comportement précèdent maintes fois le changement structural et même déterminent la direction de celui-ci.Comme exemple d'un concept qui mérite un traitement plus évolutionniste qu'il ne reçoive en général, la néoténie a été examinée. Il paraît que l'on a fait beaucoup d'erreurs en ne tenant pas compte des forces sélectives engagées. Une analyse au pointde-vue de la fonction a été appliquée à la théorie que les chordées ne sont que des ascidies néoténiques transfigurées par après, et il s'ensuit que cette idée n'est probablement pas correcte. Aussi les caractéristiques de l'homme généralement regardées comme neoténiques ont été discutées. Il en résulte que, en désignant légèrement et sans analyse plusieurs changements évolutionnaires comme néoténie, on a plutôt obsurci qu'éclairci leur signification. Ce ne sont pas les traits néoteniques de l'homme qui ont joué le rôle principal dans l'évolution humaine; au contraire, ils n'apparaissent qu'après l'acquisition de quelques nouvelles caractéristiques qui ne se trouvent ni dans l'adulte ni dans les phases plus jeunes des autres primates.Sogar heutzutage, ein Jahrhundert nach dem Erscheinen der „Origin of Species”, zeigt die jetzige zoologische Literatur oft eine unzulängliche Einsicht in die Folgerungen, zu denen die jetzt allgemein akzeptierte Annahme leitet, dass die natürliche Selektion die Richtung des Evolutionsprozesses bedingt.Dies ist teilweise zu sehen als eine Reaktion gegen eine einseitige Teleologie und gegen das Lamarckismus. Bei der Ablehnung der TheseLamarck's, dass die Aktivitäten eines Tieres einen direkten Einfluss ausüben auf seine erbliche Konstitution, nimmt man oft an, dass dies bedeutet, dass derartige Aktivitäten demnach nichts zur Sache tun bei dem Studium der Evolution. Zu einer derartigen Konklusion ist man jedoch nicht berechtigt, denn, obwohl die Aktivitäten die Evolution nicht direkt beeinflussen können mittels der Erblichkeit, so können sie dies jedoch indirekt, weil sie die Richtung der selektiven Kräfte, welche auf das Organismus einwirken, bestimmen. Es werden Argumente gegeben, welche die Konklusion rechtfertigten, dass Änderungen in Gewohnheit und Verhalten oft Strukturänderungen vorhergehen und tatsächlich die Richtung dieser letztgenannten bestimmen. Die Neotenie wirdt als ein Beispiel eines Begriff betrachtet, welcher eine mehr evolutionäre Behandlung verdient als bisher geschehen ist. Es ergibt sich dass man viele Irrtümer hat gemacht, indem man den betreffenden selektiven Kräften keine Rechnung getragen hat. Eine Analyse der Theorie, welche die Chordaten als neotenische Ascidien betrachtet, wird von einem funktionellen Gesichtspunkt aus durchgeführt. Daraus scheint der Schluss berechtigt, dass diese Theorie falsch ist. Auch werden die menschlichen Kennzeichen, welche gewöhnlich als neotenische betrachtet werden, besprochen. Die Konklusion lautet, dass, wenn man leichtfertig und ohne genügende Analyse den Zettel „Neotenie“ für mancherlei evolutive Änderungen anwendet, man die richtige Bedeutung dieser Erscheinung vielmehr verdunkelt als aufklärt: nicht die neotenische Kennzeichen des Menschen sind am wichtigsten in seiner Evolution; in Gegenteil sie erscheinen nur sekundär, nachdem die neuen Kennzeichen, welche sich weder in den Erwachsenen noch in den jüngeren Stadien von den anderen Primaten finden lassen, erschienen sind.

A few months ago General Smuts, as Rector of St. Andrews University, addressed a stirring appeal to the youth of the world to dedicate itself to the defence of the threatened cause of Freedom. As a young man, General Smuts fought in the Anglo-Boer war for the political freedom of the South African Republics. As a member of the British War Cabinet during the Great War, he was prominent among the Allied leaders in what was declared to be a (...) war to “make the world safe for democracy”. As a signatory of the Treaty of Versailles, he was the first outstanding statesman who, on the very morrow of the signing, had the courage to confess the inadequacies of that settlement, and to appeal to a war-torn world to lay aside the passions of bitter conflict and return to sanity and co-operation. In the League of Nations, which he, more than anyone else, helped to conceive and bring into being, he has sought to create the machinery for the peaceful co-operation between nations. (shrink)

This collection of thirteen essays, several of which appear in print for the first time, reveals in concrete fashion Professor Grene’s intellectual evolution from positivistic criticism of Heidegger to more recent censures of empiricism as "a singularly narrow metaphysic disguised as antimetaphysical". Although most of these essays are less than ten years old, she marks her terminus a quo by including a 1938 piece, "A Note on the Philosophy of Heidegger: Confessions of a Young Positivist". In fact, a critical (...) attitude toward her former professor is one of the constants throughout this volume. At the base of her appraisal of Heidegger lies a personal revulsion at the man’s politics and a skeptical attitude toward his obscurantism and the cult which has developed around him. In Chapter VI, "Heidegger: Philosopher and Prophet", she weighs the proportion of "trickery to truth" in his earlier and later works and finds the balance moving decisively toward trickery as the years progress. By now, however, she has come to respect the Heideggerian message that human existence is radically finite—"this is the root concept of all existentialist literature, which received in Sein und Zeit its definitive philosophic expression" —and that "language is poetry, and literal language but a desiccated and residual poetry". She expands the latter theme along her own lines in Chapter XI, "The True Teachers of Mankind", by marshaling "a series of possible grounds for a defense of poetic language in the form of a transcendental argument". In effect, she adopts von Humboldt’s notion of language as "a world between minds and things" and argues that this feature is uniquely evident in poetry, concluding that "if language without this quality would not be language, then the poetic use of speech is indeed a necessary condition for the existence of language as such". Among those cited in support of her claim, Jacques Derrida merits the greatest attention. He emerges at the center of her next essay, "Life, Death, and Language: Some Thoughts on Wittgenstein and Derrida", though ultimately to be held at some distance along with the later Wittgenstein himself for offering us "Wonderland philosophies". Two essays which share the title of the collection analyze respectively the European sources of recent Anglo-American philosophy and the reception of continental philosophy in America. And the whole is introduced by reflections on the apparent inconclusiveness of philosophical inquiry. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, and (...) actually restricts itself to justifying the tridimensionality of extension. (shrink)

The treatment decisions of competent adults, especially treatment refusals, are generally respected. In the case of minors something turns on their age, and older minors ought increasingly to make their own decisions. On the other hand, parents decide on behalf of infants and young children. Their right to do so can best be justified in terms of the importance of preserving intimate family relationships, rather than in terms of the child's best interests, although the child's best interests will most (...) often follow from this arrangement. Nevertheless, there are and ought to be legal, ethical, and financial constraints on parental decision making. (shrink)

IX. 6. 12. (The young nobles of Capua describe the bearing of the Romans released from the Caudine Forks after having passed under the yoke.).

Both unipolar and bipolar depression have been linked with impairments in executive functioning. In particular, mood symptom severity is associated with differences in common EF, a latent measure of general EF abilities. The relationship between mood disorders and EF is particularly salient in adolescence and young adulthood when the ongoing development of EF intersects with a higher risk of mood disorder onset. However, it remains unclear if common EF impairments have associations with specific symptom dimensions of mood pathology such (...) as blunted positive affect, mood instability, or physiological arousal, or if differences in common EF more broadly relate to what is shared across various symptom domains, such as general negative affect or distress. To address this question, bifactor models can be applied to simultaneously examine the shared and unique contributions of particular mood symptom dimensions. However, no studies to our knowledge have examined bifactor models of mood symptoms in relation to measures of common EF. This study examined associations between common EF and general vs. specific symptom dimensions using structural equation modeling in adolescents and young adults with varying severity of mood symptoms. A General Depression factor capturing shared variance across symptoms statistically predicted lower Common EF. Additionally, a factor specific to physiological arousal was associated with lower Common EF. Anhedonia-specific and Mania-specific factors were not significantly related to Common EF. Altogether, these results indicate that deficits in common EF are driven by, or reflect, general features of mood pathology that are shared across symptom dimensions but are also specifically associated with physiological arousal.

This new study of modern educational thought relates the selected thinkers and theories to a profound change in the way in which men have come to understand themselves and the world. The theories of Rousseau, Kant, Froebel, Hegel, Marx, Nietzsche contemporary English-speaking philosophers and schemes of education, Sartre, Helvetius and B.F. Skinner, are shown, in separate studies, to be variations upon the theme of man as a self-defining and self-legislating subject in a world that does nothing to present him with (...) any Law or Way. Education therefore becomes a problem, a matter of arbitrary selection of what the young are to be taught and to do. (shrink)

Los autores se preguntan por el aporte real de los biocombustibles a la solución de los problemas ambientales. Después de analizar las actuales formas de producción en Brasil, sostienen que la expansión de éstos presionará indirectamente hacia la deforestación, contribuyendo así aún más al calentamiento global. Señalan lo falaz del discurso que justifica la expansión de los biocombustibles por su aporte a la generación de empleo. Sostienen que es fundamental incorporar los requerimentos de sostenibilidad en la cadena de producción para (...) garantizar competitividad a los países potencialmente exportadores, pero que aún así esa solución es limitada ya que todas las energías alternativas y renovables juntas, no suplirían las proyecciones del patrón de consumo mundial.

A critical and constructive discussion of philosophical questions which have particular bearing on the formulation of educational aims.

The Pseudo-Science of B.F. Skinner was Professor Tibor Machan's first book. Now, nearly forty years after its initial publication and after three dozen additional books published by Machan, it is available again through University Press of America. This study is still alive with its initial inquiry into the work of B.F. Skinner, and it is just as influential upon young students today as it was forty years ago. Was Skinner a bona fide scientist or an amateur metaphysician? Was Skinner (...) correct to hold that only what can be observed matters when it comes to understanding ourselves? Was he correct that free will is fictional and morality is pre-scientific? Professor Machan's fascinating inquiry into Skinner's radical studies is a salute and a challenge to the corpus of his work.

- How can anthropology improve our understanding of the interrelationship between nature and culture? - What can anthropology contribute to practical debates which depend on particular definitions of nature, such as that concerning sustainable development? Humankind has evolved over several million years by living in and utilizing 'nature' and by assimilating it into 'culture'. Indeed, the technological and cultural advancement of the species has been widely acknowledged to rest upon human domination and control of nature. Yet, by the 1960s, the (...) idea of culture in confrontation with nature was being challenged by science, philosophy and the environmental movement. Anthropology is increasingly concerned with such issues as they become more urgent for humankind as a whole. This important book reviews the current state of the concepts of 'nature' we use, both as scientific devices and ideological constructs, and is organised around three themes: - nature as a cultural construction; - the cultural management of the environment; and - relations between plants, animals and humans.

This volume critically and constructively discusses philosophical questions which have particular bearing on the formulation of educational aims. The book is divided into three major parts: the first deals with the nature of education, and discusses the various general aims, such as 'mental health', 'socialization' and 'creativity' which have been thought to characterize it; the second section is concerned with the nature of reason and its relationship to feeling, will and action; finally the development of different aspects of reason in (...) an educational context is considered.

ALTHOUGH THE IDEA OF A VIOLATION OF NATURAL LAW IS NOT NECESSARILY INVOLVED IN THE IDEA OF THE MIRACULOUS, THERE IS "ONE KIND" OF MIRACLE WHICH SEEMS TO INVOLVE IT. HUME’S DISCUSSION OF THE EVIDENCE FOR MIRACLES RELATES TO THIS KIND AND IS INTERPRETABLE AS AN ARGUMENT AGAINST ITS POSSIBILITY. ALSO THERE IS AN ARGUMENT THAT THE EXPRESSION "VIOLATION OF NATURAL LAW" SIGNIFIES A CONFUSION IN WHICH THE IDEAS OF NATURAL LAW AND LEGAL LAW COLLAPSE INTO EACH OTHER. NEITHER OF (...) THESE ARGUMENTS IS EFFICACIOUS. FURTHERMORE, THE CONTENTION THAT THERE CAN BE NO SUCH THING AS ESTABLISHING THE "ABSENCE" OF A NATURAL CAUSE IS OPEN TO OBJECTION. HOWEVER, TO BE CONCEIVED AS A VIOLATION OF NATURAL LAW, A MIRACLE MUST BE THOUGHT OF AS AN OCCURRENCE WHICH IS BOTH EMPIRICALLY CERTAIN AND CONCEPTUALLY IMPOSSIBLE--WHICH OUGHT TO MAKE THE NOTION RIDICULOUS.

Being a player with an F. A. Premier football academy is very prestigious for young players, but it can also be very stressful too. Coping with stress is particularly important given that one of the undesirable consequences linked to chronic stress is athlete burnout, which may also negatively impact psychological well-being. Understanding the most effective ways to cope with stress, therefore, is important for optimizing academy athlete education. Consequently, the aim of the present study was to examine whether coping (...) predicted changes in athlete burnout, and whether athlete burnout predicted changes in well-being across 14 weeks of the competitive season. A sample of 26, under-18 and under-23, male F.A. Premier academy athletes completed weekly assessments of coping, athlete burnout, and psychological well-being on 14 separate occasions. The results of within-person analyses revealed that task-oriented coping predicted decreases in athlete burnout, which in turn predicted decreased well-being. Teaching high-level academy athletes task-oriented coping strategies may be useful in reducing athlete burnout, which may additionally protect athletes' well-being. (shrink)

All football teams that compete within the F. A. Premier League possess an academy, whose objective is to produce more and better home-grown players that are capable of playing professionally. These young players spend a large amount of time with their coach, but little is known about player’s perception of the coach-athlete relationship within F.A. Premier League Academies. The objectives of this study were to examine whether perceptions of the coach-athlete relationship changed over six months and if the coach-athlete (...) relationship predicted self-reported goal achievement among F. A. Premier League academy players. This study included cross-sectional (n = 104) and longitudinal (n = 52) assessments, in which academy soccer players completed a measure of the coach-athlete relationship and goal achievement across either one or two time periods. The cross-sectional data were subjected to bivariate correlations, whereas the longitudinal data were analyzed using multiple regressions. Perceptions of the coach-athlete relationship remained stable over time. The coach-athlete relationship predicted the achievement of mastery goals six months later. Enhancing the quality of the coach-athlete relationship among elite adolescent athletes appears to be a suitable way of maximizing mastery achievement goals, particularly among developmental athletes who participate in team sports.
