Overview The evolution of multicellularity raises questions regarding genomic and developmental commonalities and discordances, selective advantages and disadvantages, physical determinants of development, and the origins of morphological novelties. It also represents a change in the definition of individuality, because a new organism emerges from interactions among single cells. This volume considers these and other questions, with contributions that explore the origins and consequences of the evolution of multicellularity, addressing a range of topics, organisms, and experimental protocols. Each section focuses on (...) selected topics or particular lineages that present a significant insight or challenge. The contributors consider the fossil record of the paleontological circumstances in which animal multicellularity evolved; cooptation, recurrent patterns, modularity, and plausible pathways for multicellular evolution in plants; theoretical approaches to the amoebozoa and fungi (cellular slime molds having long provided a robust model system for exploring the evolution of multicellularity), plants, and animals; genomic toolkits of metazoan multicellularity; and philosophical aspects of the meaning of individuality in light of multicellular evolution.

In the modern world of total technologization, scientific knowledge devoid of worldview correction (humanitarian expertise) carries a threatening tendency of self-denial: without a constant, philosophically correct transformation of objective knowledge about certain fragments (branches) of the surrounding reality into human knowledge (questions) about itself, the practical effectiveness of such knowledge inevitably accumulates in itself the threat of practical helplessness. Aim and the tasks of the research. Based on an in-depth analysis of the category of existence, as well as on modern (...) philosophical reflections on the methodological and cognitive insolvency of the idea of the world, to find out the real meaning of those changes that this idea meaningfully undergoes in the conditions of the modern total technologization of human life. The research methodology. From a methodological point of view, the author prefers a dialectical approach, considering the analyzed phenomena, regardless of the mode of their reality, in their development and internally contradictory essence. H. Plesner’s theory of eccentric positionality serves as a certain base point for the analysis of human nature and, accordingly, the world of human existence. Research results: The problematic existence of the world and the epistemological «failure» of the corresponding category, declared in some modern philosophical reflections, are connected exclusively with its anthropological and worldview function, which is based on the fundamental uncertainty of a man’s place in the world. The «worthlessness» («futility») of worldview thematization is derived from the allencompassing inability of the human figure in the world, from that «emptiness» and «invisibility» (specific own transparency) of the spiritual dimension of human existence, on which, however, this existence is based. Discussion. The human «option» of fulfilling the unity of living being can be characterized as extremely intense. In this variant, the phylogenetic line of development turns into an ontogenetic point of worldliness devoid of predetermined content, a fundamentally new type of integration. The horizons of such integration far exceed primarily because of its understanding. And the subject of such a meaningful life is forced to integrate everything that happens to him every time into a certain system (synthesis) of the world. That subjectivity the world has distinguishes the subject from the thing. Subjectivity and the world mutually belong to each other - they are correlative. A thing exists because it is what it is. The subject (and with it his world) does not exist like that. A subject is how and to what it relates. But the relation «how» and «to what» is not carried out completely anew and isolated every time, but exists in its multiplicity in a certain relationship. Each individual case, each individual action (method of action) acquires its meaning from a wider, structured context – in whole or in part. This context is the «world», the «life world» of the real subject, or the «world» as an anthropological idea. Conclusions. The task of modern humanitarianism is not only to find opportunities for rational use of the fact of the fundamental openness of the human being, but also to cultivate the ability to reconcile a man with himself, to accept himself. This gives us certain reasons to hope for the enduring significance of worldview thematization. Criticism regarding the seemingly paradoxical conclusion that to become a man, one must already be one, could be considered fair, but only if one does not take into account the principled nature of such an aphoristic position, because this is exactly how the human world exists - as the art of tolerance uncertainty.

It has been argued that if an animal is psychologically like us, there may be more scientific reason to experiment upon it, but less moral justification to do so. Some scientists deny the existence of this dilemma, claiming that although there are scientifically valuable similarities between humans and animals that make experimentation worthwhile, humans are at the same time unique and fundamentally different. This latter response is, ironically, typical of pre-Darwinian beliefs in the relationship between human and non-human animals. Another (...) irony is that debate about such issues has facilitated the participation once more of philosophers in questions concerning experimental psychology: ironic because laboratory-oriented psychologists, especially since the turn of the last century, had been eager to establish the independence of their subject from any influence of philosophy and its investigative methods, as well as from any kind of anthropomorphism.In Britain, certainly more so than in the United States, ethical constraints have prevented the development of psychological research with animals along certain routes. By the 1980s British professional and academic societies had published codes of conduct and guidelines for their members, in part responding to public concern about the welfare of animals in the psychological laboratory. What led to the establishment of these codes and guidelines? This paper analyses the historical background against which professional concern for ethical cost in experimental animal psychology began to take shape, leading to the societies' open pronouncements of the 1980s.

Aischylos darf als der eigentliche Schöpfer der Tragödie als literarischer Kunstform gelten, so sehr diese im 5. vorchristlichen Jahrhundert auch an ihren kultischen Ursprung gebunden bleibt. Aischylos führt den zweiten Schauspieler ein und nutzt technische Erfindungen zur Steigerung szenischer Effekte. Außerdem ist er der große Gestalter der tetralogischen Komposition, d.h. der Verbindung dreier Tragödien und eines Satyrspiels zu einer Handlungseinhait, die es ihm ermöglicht, die Verkettung von Hybris, Ate und Dike an ganzen Geschlechtern über Generationen hin zur Darstellung zu bringen. (...) Im Mittelpunkt seines Denkens steht die notwendig schuldhafte Existenz des handelnden Menschen, für den die Erfüllung einer überpersönlichen Forderung zugleich den Verstoß gegen eine andere, ebenso gültige Norm bedeutet. Überbrückt wird diese tragische Weltsicht im Glauben an die von Zeus repräsentierte Weltordnung, die den Menschen im einzelnen zwar unbegreiflich bleibt, deren grundsätzliche Sinnhaftigkeit sich ihm jedoch im Leiden erschließt. Adäquaten Ausdruck findet dieses Denken in einer urtümlichen und gewaltigen Sprache, deren Übersetzung in der hier vorliegenden Ausgabe philologisch präzis ist und gleichzeitig das Verständnis des aischyleischen Dramas erleichtert.

Except for the work of Hiralal Haldar published in 1927, Pucelle's book is the first systematic account of the influence of German idealism in England. On the flyleaf he quotes Muirhead's remark in his study of Coleridge that "the history in England of what at the present day is known as idealistic philosophy still remains to be written". The implication may seem somewhat unfair to Muirhead's own subsequent effort to fill the gap in The Platonic Tradition in Anglo-Saxon Philosophy. But (...) this is not the case. Muirhead characterized his own work as "studies" and made no attempt to write a complete history, whereas Pucelle gives a full account of the idealist "school" and even sketches in the related currents of thought in poetry and theology. Careful comparison reveals that he has tried as far as possible to avoid going over the ground that Muirhead had already covered. Thus he gives a full account of the work of Ferrier, where Muirhead was only interested in Ferrier's abortive struggle to understand Hegel; but when he comes to the Essays in Philosophical Criticism he is content simply to indicate their nature and the reason for their importance, and to refer his readers to Muirhead's full analysis. Even in the case of Bradley, who is treated at length by both authors, the two discussions are complementary in that Muirhead was concerned with the development of Bradley's thought while Pucelle treats it as a system.

This commentary is an attempt to sharpen some of the issues raised in the paper and thereby increase the generality of the proposal. Some implications of an exact definition of behavior for strategies of measurement and hence behavioral variability are discussed. The role of both respondent and operant behavior in natural selection is emphasized.

HIT produces category-specific deficits without category- specific mechanisms by assuming that differences in properties of objects are transparently converted into differences in representational format. A complete model would specify the mechanisms that accomplish this. Such category-specific mechanisms may have evolved because assumptions about the properties of some kinds of objects (e.g., living things) are invalid for others (e.g., artifacts).

Die neue herausragende Übertragung. Cicero verfasste "De officiis" in den Monaten nach der Ermordung Caesars als Vermächtnis an seinen Sohn. Von allen Werken Ciceros hat es am stärksten auf die Nachwelt gewirkt. Es wurde am häufigsten übersetzt und kommentiert. Voltaire und Friedrich der Große hielten "De officiis" für das beste Buch zum Thema moralisches Verhalten.
