It is desirable that the antecedents of existing, highly specialised, evolutionary mechanisms in animals be sought. The study of the lower Metazoa and especially of their simpler reproductive processes suggests that asexual reproduction is the primitive evolutionary mechanism from which the more advanced sexual mechanisms have evolved. A study of the metagenetic cycles of Coelenterata and Platyhelminthes seems to throw much light upon their prophylogeny and indicates that: Such cycles seem to provide the closest possible recapitulatory parallelism between phylogeny and (...) ontogeny. The Hydrozoa are ancestral to the other classes of Coelenterata. The polypoid adult is more primitive than the medusoid adult. The sporocysts, rediae and scolices represent the more primitive types of adults in their respective ontogenies and phylogenies.On avance la théorie qu'il y a eu une évolution des mécanismes évolutionnaires depuis les stades primitifs jusqu'aux stades avancés. D'après cette théorie les premières étapes dans l'évolution des Métazoaires inférieurs se sont effectuées par la reproduction asexuelle avant que les mecanismes sexuels très spécialisés se soient manifestés.Des preuves à l'appui de cette théorie découlent: de la rencontre actuelle d'une reproduction asexuelle chez des animaux, avec l'indication que sa simplicité est, dans la plupart des cas, originelle, et des cycles d'évolution des Coelentérés et Platyhelminthes qui sont métagénésiques. Leurs cycles peuvent s'interpréter comme partant de stades reproductifs asexuels pour évoluer vers des formes se reproduisant sexuellement.On croit que les organismes ne pouvant se reproduire que sexuellement sont plus avancés que ceux qui peuvent se reproduire asexuellement, ou à la fois sexuellement et asexuellement.Cette théorie a d'importantes implications pour l'étude de la métagenèse, de la récapitulation et de la phylogénie chez les Métazoaires inférieurs; elle exemplifie, dans l'étude de ces phénomènes, la nouvelle orientation qu'on a appelée Prophylogénie.In dieser Arbeit wird eine Theorie entwickelt, die besagt, dass eine Fortentwicklung der Evolutionsmechanismen von primitiven zu fortgeschrittenen Stufen besteht. Dieser Theorie nach haben sich die niedrigeren Metazoen ursprünglich nur ungeschlechtlich entwickelt und fortgepflanzt. Erst später haben sich die höchst spezialisierten geschlechtlichen Mechanismen entwickelt.Belege für diese Theorie sind: Noch heute kommt die geschlechtslose Fortpflanzung in Tieren vor, was dafür spricht, dass ihre Einfachheit in den meisten Fällen ursprünglich ist. Die Lebenskreisläufe der Metagenetischen Coelenteraten und Platyhelminthen lassen sich interpretieren als bestehend aus ursprünglich ungeschlechtlichen Fortpflanzungsstufen, die jedoch später in Formen mit geschlechtlicher Fortpflanzung übergehen.Es wird behauptet, dass Organismen mit nur geschlechtlicher Fortpflanzung weiter fortgeschritten sind als solche mit nur ungeschlechtlicher oder mit sowohl ungeschlechtlicher als auch geschlechtlicher Fortpflanzung.Diese Theorie ist wichtig für das Studium der Metagenese, Rekapitulation und Phylogenie in den niedrigen Metazoen und veranschaulicht die Prophylogenie, d.h. die neue Methode im Studium dieser Erscheinungen.

Missing from Bering's account of the evolutionary origins of existential reasoning is an explicit developmental framework, one that takes into account community input. If Bering's selectionist explanation was on target then one might predict a unique and relatively robust developmental trajectory, regardless of input. Evidence suggests instead that children's existential reasoning is contingent on their developing theory of mind.

St Augustine himself recognised in Retractationes that De Mendacio is a difficult text to understand, because its argument is both complex and dialectical. Understanding the treatise has been further complicated by St Thomas Aquinas’ reading of it in the light of Aristotle, and under the influence of a possibly flawed textual tradition. This article clarifies Augustine’s well known eight categories of lies to resituate them in the social experience of Augustine and his contemporaries. It shows that Augustine’s argument and exegesis (...) are strikingly exploratory and undogmatic. His hard-won conclusion is driven by a demanding understanding of sanctity. A synopsis of the argument of De Mendacio is appended. (shrink)

In the United States, lay-adults with a range of educational backgrounds often conceptualize species change within a non-Darwinian adaptationist framework, or reject such ideas altogether, opting instead for creationist accounts in which species are viewed as immutable. In this study, such findings were investigated further by examining the relationship between religious belief, scientific expertise, and ecological reasoning in 132 college-educated adults from 6 religious backgrounds in a Midwestern city. Fundamentalist and non-fundamentalist religious beliefs were differentially related to concepts of evolution, (...) adaptation, and extinction. Biological expertise and creationism were significantly and differentially related to the endorsement of the Darwinian concept of common descent. Yet, creationists were more likely to reject macroevolutionary than microevolutionary concepts. Overall, the greater the taxonomic distance between species, the less likely were participants to agree that species-pairs had common ancestors. It is argued that lay adults from contemporary industrialized societies adopt a view of evolution in which species adapt to novel environments, but remain the same "kind" despite changes. Therefore, extinction is considered unlikely and the relations between micro- and macroevolution misconstrued. Lay-adults' species concepts appear to be an amalgam of a common-sense understanding of species and of evolutionary ideas, modified but not transformed by religious and scientific beliefs. Finally, it is argued that the development of scientific expertise does not involve the radical transformation of ingrained worldviews. Rather, scientists select specializations that are compatible with their existing philosophies, then consciously apply the constructs of their disciplines in order to transcend their common-sense folk beliefs.

Children and adults from theus and China heard about people who died in two types of narrative contexts – medical and religious – and judged whether their psychological and biological capacities cease or persist after death. Most 5- to 6-year-olds reported that all capacities would cease. In theus, but not China, there was an increase in persistence judgments at 7–8 years, which decreased thereafter.uschildren’s persistence judgments were influenced by narrative context – occurring more often for religious narratives – and such (...) judgments were made especially for psychological capacities. When participants were simply asked what happens to people following death, in both countries there were age-graded increases in references to burial, religious ritual, and the supernatural.

Insight has been investigated under the assumption that participants solve insight problems with insight processes and/or experiences. A recent trend has involved presenting participants with the solution and analysing the resultant experience as if insight has taken place. We examined self-reports of the aha experience, a defining aspect of insight, before and after feedback, along with additional affective components of insight (e.g., pleasure, surprise, impasse). Classic insight problems, compound remote associates, and non-insight problems were randomly interleaved and presented to participants. (...) Solution feedback increased ratings of aha experience in both insight and non-insight problems, with this result being driven by responses to solutions that were initially incorrectly generated. Ratings of aha for correctly generated solutions decreased after the correct solution was presented. These findings have implications for insight research paradigms as well as informing teaching methods. (shrink)

The ability to generate diverse ideas is valuable in solving creative problems ; yet, however advantageous, this ability is insufficient to solve the problem alone and requires the ability to logically deduce an assessment of correctness of each solution. Positive schizotypy may help isolate the aspects of divergent thinking prevalent in insight problem solving. Participants were presented with a measure of schizotypy, divergent and convergent thinking tasks, insight problems, and non-insight problems. We found no evidence for a relationship between schizotypy (...) and insight problem solving. Relationships between divergent thinking and insight problem solving were also surprisingly weak; however, measures of convergent thinking had a stronger relationship with problem solving. These results suggest that convergent thinking is more important than divergent thinking in problem solving. (shrink)

In this article, I argue that Donna Haraway's figure of the cyborg needs to be reassessed and extricated from the many misunderstandings that surround it. First, I suggest that we consider her cyborg as an ethical concept. I propose that her cyborg can be productively placed within the ethical framework developed by Luce Irigaray, especially in relationship to her concept of the “interval between.” Second, I consider how Haraway's “cyborg writing” can be understood as embodied ethical writing, that is, as (...) a contemporary écriture feminine. I believe that this cyborgian “writing the body” offers us a way of both creating and understanding texts that think through ethics, bodies, aesthetics, and politics together as part of a vital and relevant contemporary feminist ethics of embodiment. I employ the term “poethics” as a useful way to describe such a practice. (shrink)

As medical science continues its rapid advances, questions are raised that have more to do with theology than with technology: Where is God when I am hurt or suffering? What role does God play in my healing? "Pain Seeking Understanding" examines how believers and nonbelievers alike wrestle with questions of faith when confronted with pain and suffering that medicine alone cannot treat. Margaret Mohrmann and Mark Hanson call upon fellow experts in the fields of medicine, ethics, theology, and pastoral (...) care to help them weave the complex story of faith and science working together to ease suffering -- and to help broaden our understanding of God's role in suffering and healing.

The ancient scholia and various modern editors interpret these lines as a description of the prodigies which followed the death of Caesar. It is bold to criticize a view so widely held, but its acceptance, to me, involves considerable difficulties. The first is the long interval between Caesar's death and the date of the Ode. About this date editors vary, but the general view is that it belongs either to the year 29 or 28 B.C.

Studies of participatory governance generally examine the input and/or output side of policy processes. Often neglected is the throughput: Does the state have the political and technical capacity to implement the decisions that deliberative bodies make? In this study of Brazilian river-basin committees, the authors find that activists inside and outside the state often must collaborate to overcome resistance to change and provide state officials with resources they lack. They argue that this does not constitute the transfer of state responsibility (...) to private actors but rather the mobilization of a state's capacity to defend the public interest. (shrink)

It seems to be becoming a fable convenue that Propertius opened his most elaborate book with a poem of hopeless illogicality. Shackleton Bailey complains on 3. 1. 25, ‘nam quis perhaps = quisnam as in Virg. Georg. 4. 445; see on 3. 11. 27. Even so, the absence of logical sequence from the theme of 21–4 to that of 25–32 is noteworthy and characteristic… In 33 the poet becomes conscious of having lost his way and uses Homer as a bridge (...) back to the earlier motif.’.

This review both praises Richard Miller's book--a thoughtful, judicious, and comprehensive analysis of bioethics for the pediatric age group, notably the first effort worthy of the name--and points out the work still to be done in this area, work firmly based in and illuminated by Miller's ground-breaking thesis. Specifically, the book rightly compels us to recognize obligations of beneficence as primary and to refocus on the child's basic interests, rather than putative "best" interests. There remains much to be done in (...) defining and discerning basic interests and in distinguishing whose interests are on the table when decisions are being made for seriously ill and dying children.
