The author of this text argues that the methodological issues in bioethics mirrors the experience of moral pluralism in a secular society. The different methods that have been used in the field reflect the different moral views found in a pluralistic society.

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

Context: Constructivist approaches to cognition have mostly been descriptive, and now face the challenge of specifying the mechanisms that may support the acquisition of knowledge. Departing from cognitivism, however, requires the development of a new functional framework that will support causal, powerful and goal-directed behavior in the context of the interaction between the organism and the environment. Problem: The properties affecting the computational power of this interaction are, however, unclear, and may include partial information from the environment, exploration, distributed processing (...) and aggregation of information, emergence of knowledge and directedness towards relevant information. Method: We posit that one path towards such a framework may be grounded in these properties, supported by dynamical systems. To assess this hypothesis, we describe computational models inspired from swarm intelligence, which we use as a metaphor to explore the practical implications of the properties highlighted. Results: Our results demonstrate that these properties may serve as the basis for complex operations, yielding the elaboration of knowledge and goal-directed behavior. Implications: This work highlights aspects of interaction that we believe ought to be taken into account when characterizing the possible mechanisms underlying cognition. The scope of the models we describe cannot go beyond that of a metaphor, however, and future work, theoretical and experimental, is required for further insight into the functional role of interaction with the environment for the elaboration of complex behavior. Constructivist content: Inspiration for this work stems from the constructivist impetus to account for knowledge acquisition based on interaction. (shrink)

The idea of the moral good is considered a desirable and appreciated real existence. With reference to teachers it constitutes a personal pattern of judicious acting. Their special task is not only to teach necessary knowledge to students but also to instil moral conduct in them i.e. to form ‘a correct character’. This notion was present at the beginning of the 20th century and is also reflected in Archbishop Józef Bilczewski’s letter ‘The Character’ (1920). The ideas presented there remain still (...) valid also in the present historic moment of the nation. (shrink)

Venneman and colleagues argue that “do not resuscitate” (DNR) is problematic and should be replaced by “allow natural death” (AND). Their argument is flawed. First, while end-of-life discussions should be as positive as possible, they cannot and should not sidestep painful but necessary confrontations with morality. Second, while DNR can indeed be nonspecific and confusing, AND merely replaces one problematic term with another. Finally, the study’s results are not generalisable to the populations of physicians and working nurses and certainly do (...) not support the authors’ claim that there is a movement to replace DNR with AND.

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional brain metabolism measured (...) during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.

In this text, we ask if analogy can enable a dialogue between religion and the social sciences. To do so, we focus in the conflict between the biblical understanding of man as a created being and the notion of human nature as a social construct. Although there seems to be a fundamental dispute in social constructivism between nature and freedom (Ian Hacking), we consider analogical reasoning (Mauricio Beuchot) enables anthropological views, like Philip Hefner’s, that include central aspects of the doctrine (...) of creation and understand nature and freedom as complementary human features, thus allowing the desired dialogue.

A. F. Losev, one of the most important Russian philosophers and historians of ancient aesthetics and culture in the 20th century, develops in his ‘Dialectics of the Myth’ (Dialektika mifa), 1930, a personalistic ontology by using elements of neoplatonic philosophy and Orthodox Christian belief. According to Losev reality in all its different expressions and ontological strata must be understood as “mythical”, i.e. as “living mutual exchange of subject and object”. The subjective and personal aspect of reality is not grounded in (...) man’s epistemic relation to it alone; reality in itself has to be characterized as personal and subjective. The main philosophical opponent is Descartes, the founder of “modern rationalism and mechanism”. (shrink)

In examining Ennead VI 4[22], we find Plotinus in conflict with modern, i.e., Cartesian or Kantian, assumptions about the relation of soul and body and the identification of the self with the subject. Curiously, his images and exposition are more in tune with Twentieth Century notions such as wave and field. With these as keys, we are in a position to unlock the subtlety of Plotinus' analysis of the way soul and body are present together, with sensation structured through the (...) body and judgment coming from the soul. The problem of the self concerns not only the unity of the self in terms of body and soul, but also how the self is constituted in relation to other selves, both keeping its individuality and sharing its experiences at the same time.

"This fine book is ideal for introductory courses in philosophy, and it is executed and backed up by careful, sophisticated philosophical analysis and insight." —_W. Norris Clarke, S.J., Fordham University_ _ _ _Human Knowing_ is a clearly written, brief introduction that guides the reader through an exploration of sense perception, ordinary knowing, scientific knowing, and philosophic knowing. This journey culminates in a justification of philosophy as a genuine form of knowing and thus a natural prelude to metaphysics. Though Felt manages (...) to avoid technical language, the development of his argument is a genuine exercise in philosophic thinking. The outcome is a contemporary expression of a position similar to that of Thomas Aquinas, significantly enriched by insights from Bergson, Whitehead, and phenomenology. (shrink)

Context: Philosophical debates in recent decades have developed new ways of dealing with old philosophical problems such as reality, truth, knowledge, language, communication, and action. These new approaches deserve serious consideration because they can improve the discourse of radical constructivism. Problem: This paper discusses the following problem: How can we overcome dualistic and ontological approaches to basic philosophical problems – problems that are relevant to all scientific domains? Method: The method applied here can be roughly described as a transition from (...) entities/substantives/identities to actions and processes, the actions and processes from which so-called entities result. Action-orientation – or an actor-based process – is necessarily combined with sense-orientation as provided by culture and society. Results: The paper demonstrates how the problems mentioned above can be reformulated in a non-dualistic and non-ontological way. Implications: Opening up constructivist thinking to insights provided by neighbouring philosophical approaches facilitates interdisciplinary cooperation and helps overcome dualistic remnants – as well as the cognitive one-sidedness of traditional constructivism.

Gaston Fessard employs Hegel’s dialectical logic to clarify how St. Ignatius’s _Spiritual Exercises_ envisage and prepare the decisions and choices between contrasting options or major turning points in spiritual life, in moments of what Ignatius would call _Election_.

Problem: Mitterer's critique of the central argumentations of radical constructivists has been mostly neglected until today. The paper presents and evaluates his criticism and, in the second part, outlines a format of constructivism that tries to draw appropriate consequences. Solution: In his critique Mitterer explains why the radical constructivism represented above all by Maturana, Varela, von Glasersfeld or Roth still remains in a dualistic format. In his view Neurobiology is used in their writings as the indisputable basis for deriving far-reaching (...) epistemological consequences. Therefore constructivism evades self-application. To overcome this serious critique a different approach to constructivist thinking is sketched that operates without using any biological or psychological theories, tries to avoid dualism, and elaborates Mitterer's basic argument that the description of an object and the object under description are the same. Benefits: The paper shows what constructivism can learn from a serious critique and how it can be rewritten in a non-dualistic way. (shrink)
