Despite hundreds of definitions, no consensus exists on a definition of life or on the closely related and problematic definitions of the organism and death. These problems retard practical and theoretical development in, for example, exobiology, artificial life, biology and evolution. This paper suggests improving this situation by basing definitions on a theory of a generalized particle hierarchy. This theory uses the common denominator of the “operator” for a unified ranking of both particles and organisms, from elementary particles to animals (...) with brains. Accordingly, this ranking is called “the operator hierarchy”. This hierarchy allows life to be defined as: matter with the configuration of an operator, and that possesses a complexity equal to, or even higher than the cellular operator. Living is then synonymous with the dynamics of such operators and the word organism refers to a select group of operators that fit the definition of life. The minimum condition defining an organism is its existence as an operator, construction thus being more essential than metabolism, growth or reproduction. In the operator hierarchy, every organism is associated with a specific closure, for example, the nucleus in eukaryotes. This allows death to be defined as: the state in which an organism has lost its closure following irreversible deterioration of its organization. The generality of the operator hierarchy also offers a context to discuss “life as we do not know it”. The paper ends with testing the definition’s practical value with a range of examples. (shrink)

The author deals with the meaning of metamerism. Two contrary points of view may serve to clear the problem. From the morphological point of view probably outgrowth of the organism in longitudinal direction has led to the development of metameres. So the first segmentation is due to a functional differentiation. In Phylogeny this segmentation has been maintained and the originally developed metameres remain the primary morphotic units of the organisms. Further specialising of function and organ-concentration destroyed the original absolute metamerism (...) and only left a rest of the original.The functional point of view renounces an original absolute metamerism for the present moment. It only asks for the functional meaning of the segmentation in organisms, showing this segmentation. From the functional point of view it is possible that metamerism may be the morphological expression of quite different functional requirements and that in one organism the metamerism starts from another system of organs than in another.Es wird gefragt welche Bedeutung die Metamerie haben kann. Zur Erläuterung des Problems werden zwei extremen Betrachtungsweisen einander gegenübergestellt. Nach der morphologischen Betrachtungsweise hat Wachstum der Organismen in die Länge wahrscheinlich zur Ausbildung der Metamerie geführt. Diese erste Metamerie ist wahrscheinlich ein funktioneller Differenzierungsprozess gewesen.In der Phylogenese hat sich diese Metamerie behauptet und die ursprünglich entstandene Metamere sind die primären morphotischen Einheiten der Organismen geblieben. Weitergehende Funktionsspezialisierung und Organkonzentration hat die ursprüngliche absolute Metamerie vernichtet. Was davon übrig blieb sind die Reste der ursprünglichen.Die funktioneile Betrachtungsweise verzichtet vorläufig auf eine ursprüngliche absolute Metamerie. Sie fragt bloss nach der funktionellen Bedeutung, welche die Metamerie besitzt bei denjenigen Organismen, wo diese gefunden wird. Sie achtet es möglich, dass Metamerie der Ausdruck sein kann von ganz verschiedenen funktionellen Anforderungen und dass somit die Metamerie bei der einen Tiergruppe von einem ganz anderen Organsystem ausgeht wei bei einer anderen.

What is the proper role of logic in analytic theology? This question is thrown into sharp relief when a basic logical principle is questioned, as in Beall’s ‘Christ – A Contradiction.’ Analytic philosophers of logic have debated between exceptionalism and anti-exceptionalism, with the tide shifting towards anti-exceptionalism in recent years. By contrast, analytic theologians have largely been exceptionalists. The aim of this paper is to argue for an anti-exceptionalist view, specifically treating logic as a modelling tool. Along the way I (...) critically engage with Beall on the role of logic in theology, maintaining that theological inquiry is in some ways disanalogous with other theoretical enterprises. (shrink)

Open peer commentary on the article “Enacting the “Body” of Neurophenomenology: Off-Radar First-Person Methodologies in Pragmatics of Experiencing” by Jakub Petri & Artur Gromadzki. Abstract: Petri and Gromadzki have produced a thought-provoking article that, rather unfortunately, places itself wide of the mark in a couple of places. I will lay out and address their two major concerns and conclude with some remarks about their proposal for broadening the field of neurophenomenological enquiry.

Both the recent 'Warner' review of the UK research ethics committee (REC) system and the subsequent consultation document produced by the Central Office for Research Ethics Committees (COREC) emphasize the need to distinguish 'research' from what might be termed 'non-research'. This is to be determined through a process of filtering or 'triage', the intention being that RECs will avoid considering proposals with 'no material ethical issues'. In this paper we argue that trying to distinguish 'true' research from other projects is (...) counterproductive, misleading and potentially unethical. Our case is built around three assertions: (1) the distinction between research and non-research is imprecise; (2) both medical research and non-research can generate similar ethical issues; and (3) projects should be judged according to what they involve, not how they are labelled.

Barsalou's theory rightly emphasizes the perceptual basis of cognition. However, the perceptual symbols that he proposes seem ill suited to carry the representational burden entailed by the architecture in which they function, given that Barsalou accepts the requirement for productivity. A more radical proposal is needed in which symbols are largely external to the cognizer and linked to internal states via perception.

Free Speech and the Politics of Identity challenges the scholarly view as well as the dominant legal view outside the United States that the right of free speech may reasonably be traded off in pursuit of justice to stigmatized minorities. The book's innovative normative and interpretative methodology calls for a new departure in comparative public law, in which all states responsibly address their common problems, not only of inadequate protection of free speech, but also correlative failure to take seriously the (...) continuing political power of such evils as anti-Semitism, racism, sexism, and homophobia.

Upshot: In reading the commentaries, we were struck by the fact that all of them were in some capacity related to what we consider a core principle of radical constructivism - interaction. We characterize interaction from a radical constructivist perspective, and then discuss how the authors of the commentaries address one kind of interaction.

One of the most famous inscriptions to have survived from ancient Rome is the acta of the Ludi Saeculares of 17 b.c., and one of the most evocative of all epigraphic sentences occupies a line to itself : Carmen composuit Q. Horatius Flaccus. This reference to the author of the Carmen Saeculare, says Fraenkel, ‘was the result of a carefully considered decision of the highest authorities’. The degree of careful consideration is initially evident from the prominent positioning of the poet's (...) name directly above those of Augustus and Agrippa in the following line. It will also be noticed that the sentence concludes with a clausula which is one of Cicero's favourites. A further refinement emerges, however, if the poet's name is spelled out in full, something precluded by the naming conventions of the inscription:Cārmēn cōmpŏsŭīt ´ Quīntŭs Hŏrātĭūs | Flaccus.The inscribed sentence incorporates an Asclepiad line, the ‘signature’ metre of Odes 1–3, which are framed by Horace's only two poems in stichic Asclepiads. In identifying the author of the Carmen Saeculare, the sentence also acknowledges the collection of poems which won him the commission. (shrink)

A model for the trapping of animals with a circular pitfall is formulated. The model's assumptions are: The animals move independently according to the same Brownian motions. The boundary of the pitfall acts as an absorbing or elastic barrier. Initially a fixed number of animals is independently homogeneously distributed over a finite study area, or the initial positions follow a homogeneous planar Poisson process. The model depends on three free parameters: the motility of the animals, their reaction to the pitfall, (...) the initial density.It appears that the catches in disjoint time intervals are multinomially or independently Poisson distributed. The parameters of these distributions are obtained by solving certain partial differential equations. (shrink)
