With the advent of the relativity theory science has entered a transformative period in which previous certainties are undergoing critical scrutiny and renovation. Critical movements in science arise at periods of its history when its foundations are brought into question. True it is that natural philosophers still regard science as a growing body of propositions dealing with natural events enabling them to find the structural laws of the external world. But this “external world” about them changes in significance, interpretation, and (...) meaning as new epoch-making theories are propounded and experimental verification of some of their consequences tend to give them scientific plausibility.

A substantial guide providing an overview of both physicalism and metaphysical naturalism, reviewing both questions of formulation and justification for both doctrines. Includes a diagnostic strategy for understanding talk of naturalism as a metaphysical thesis.

Recent work by Jaegwon Kim and others suggest that functionalism leaves mental properties causally inefficacious in some sense. I examine three lines of argument for this conclusion. The first appeals to Occam's Razor; the second appeals to a ban on overdetermination; and the third charges that the kind of response I favor to these arguments forces me to give up "the homogeneity of mental and physical causation". I show how each argument fails. While I concede that a positive theory of (...) mental causation is desirable, there is no reason to think that functionalism renders such a theory unattainable.

Discussion of partial grounds that aren't parts of full grounds; definition of full grounding in terms of partial grounding.

Defense of an account of intrinsic properties in terms of (what is now called) grounding rather than naturalness.

Some recent trends of modern biology, which seem to have a most consequential influence to the further treatment of the problem of the origin and evolution of flowering plants, are shortly reviewed in this article.Several new discoveries and observations about pollinating insects revealed to some extent the mystery of the evolution of flower types. The deciphering of the definite signs and codes of communication among social insects and the interpretation of a well developed sign language of bees belong to the (...) most remarkable achievements of modern biology indeed. Besides its revolutionary impulse in the field of animal behavior these discoveries helped to solve several problems in the evolution of flowering plants.An attempt is made in this article to classify the existing main flower types according to their evolutionary tendency from primitive → simple → radiate → protected → zygomorphic flowers In this assortment of flower types is reflected the historical development of flowering plants since their early beginning in Cretaceous period till their domination in the recent world vegetation .In this evolution of flower types is mirrored further the progressive evolvement of numerous senses of the pollinating insects. The pollinators of the Middle Mesozoicum were surrounded by primitive flower types and could distinguish but some primitive colors like white, yellow and green.Two different methods of classification of flowering plants are used in this study. A typological assortment of flowers according to their ecological characteristics is co-ordinated with the taxonomic classification of phylogenetic groups . The evolution of angiosperms can be studied more successfully, if both the typological and taxonomic trends of this groups are analyzed.Quelques nouvelles découvertes et essais sur la dissémination du pollen par les insectes sont discutés du point de vue de l'évolution des types de fleur. L'activité sélective et la stabilité de ces insectes se trouvent être des facteurs les plus conséquents dans l'évolution des types de fleurs.Deux méthodes différentes de classification des plantes angiospermes sont employées dans cette étude. Un assortiment typologique de fleurs suivant leurs caractéristiques écologiques est coordiné avec la classification systématique des groupes phylogénétiques . L'évolution des angiospermes peut être étudiée avec plus de succès si les méthodes typologiques et systématiqes sont appliquées.Es werden in diesem Aufsatz einige neue Versuchsergebnisse über die wechselseitigen Beziehungen zwischen den pollenübertragenden Insekten und der Entwicklungsgeschichte der Blütentypen näher erörtert.Es sind unter diesen Umständen zwei verschiedene Arbeitsverfahren für die Klassifikation der Blütenpflanzen angewandt worden. Eine typologische Einteilung nach den ökologischen Merkmalen und eine systematische Schilderung nach den phylogenetischen Gruppen . Die Anwendung von diesen beiden Methoden gestattet uns eine bessere Übersicht über die Entwicklungsgeschichte der Blütenpflanzen. (shrink)

В монографии осуществляется философско-этическое исследование параметров нравственной деятельности человека в бизнес-сфере. Для специалистов.

A survey of 106 medical students assessing their interest in and attitudes to medical ethics in the curriculum is reported by the authors. Results indicate that 64 per cent of the students rated the importance of medical ethics to good medical care as high or critical and 66 per cent desired to learn more about the topic. However, in reports of patient encounters identifying ethical issues, less than six per cent of the students reported a frequency of more than one (...) such patient encounter per week. The students also demonstrated a greater awareness of more obvious ethical issues than of more subtle, less publicised issues. When asked how medical ethics should be taught, the students clearly affirmed a desire for an integrated exposure to the subject throughout the medical curriculum. Possible implications of these findings for medical education are discussed. (shrink)

Fornix problem: Why do lesions of the fornix, which connects the hippocampus (HF) to the medial mammillary nucleus (MMN), often cause no deficits in tasks severely affected by lesions of HF or MMN? Solution: The direct HF feedback to antero ventral (AV) thalamus (MMN [Rightarrow A: implies] AV [Leftrightarrow A: l&r dbl arrow] HF), which is blocked by MMN lesions but not fornix lesions, is sufficient for nonscene-relevant consolidation.

I agree with Revonsuo that dreaming, particularly about risky scenes, has a great selective advantage. Although the paleoamygdala system generally facilitates stress and alarm, the system which inhibits stress and alarm, initiates bold actions, and mediates learning in risky scenes is the arche, hippocampal system (Papez circuit). Because all thalamic nuclei are inhibited during sleep except arche, Papez probably also dreams in risky scenes. [Revonsuo].

Originally published in 1933, this book was written to provide the younger reader with a guide to the basic elements of economics, preparing them with the tools to earn a living and spend money in a responsible fashion. The text was based on a series of lessons 'given to pupils of ordinary ability during their last two terms in a reorganized senior school'. Illustrative figures are included. This book will be of value to anyone with an interest in economics and (...) the history of education. (shrink)
