Open peer commentary on the article “Examining the Role of Re-Presentation in Mathematical Problem Solving: An Application of Ernst von Glasersfeld’s Conceptual Analysis” by Victor V. Cifarelli & Volkan Sevim. Upshot: Education researchers often explain student activity in terms of general thinking and learning processes, including those identified by Cifarelli and Sevim. In this commentary, I refocus Cifarelli and Sevim’s discussion in order to hypothesize the organization of mental actions that comprise and support those learning processes.

Upshot: The commentaries concentrate mostly on ontological issues but overlook the main epistemological argument in my target article. This argument refers to the conditions that make cognition possible, and to the limits of cognition. These are important for two reasons: they have ontological consequences and they limit the theory’s contingency.

Open peer commentary on the article “The Banathy Conversation Methodology” by Gordon Dyer, Jed Jones, Gordon Rowland & Silvia Zweifel. Upshot: Banathy’s Conversation Methodology and the conversation events where it was developed and practiced had a profound effect on my role as a scholar-practitioner. In this commentary, I reflect on the impact of the BCM in my professional practice as an educator, facilitator, and consultant within the field of social innovation, where participatory processes for eliciting the wisdom of the group (...) are essential.

Welcome to the world of cutting-edge math, physics, and neuroscience, where the search for the ultimate vacuum, the point of nothingness, ground zero of theory, has rendered the universe deep, rich, and juicy. "Modern physics has animated the void," says K. C. Cole in her entrancing journey into the heart of Nothing. Every time scientists and mathematicians think they have reached the ultimate void, new stuff appears: a black hole, an undulating string, an additional dimension of space or time, repulsive (...) anti-gravity, universes that breed like bunnies. Cole's exploration at the edge of everything is as animated and exciting as the void itself. Take Cole's hand on this adventure into the unknown, and you'll come back informed, amused, and excited.

Some practical problems in the teaching of ethics to medical students are described. The definition of the objectives of the course remains the central aspect, and is more important than the specific content. The use of student projects, buzz groups, case histories and discussion points is described. There is a need for student assessment or examination at the end of the course. The teachers require a broad background in philosophy, clinical medicine and teaching skills. The learning of the teachers may (...) be as important as that of the students. (shrink)

Quality of life is a difficult concept to define and to measure. An hypothesis is proposed which suggests that the quality of life measures the difference, or the gap, at a particular period of time between the hopes and expectations of the individual and that individual's present experiences. Quality of life can only be described by the individual, and must take into account many aspects of life. The approach is goal-orientated, and one of task analysis. The hypothesis is developed in (...) a diagramatic way, and several methods of testing the hypothesis suggested. (shrink)

I Propose to re-explore here some aspects of a very shop-worn question: ‘Was Hobbes in any sense an atheist?’ Three centuries ago, Hobbes's personal security in part depended on the way his contemporaries answered this question; today, the validity of several current accounts of his philosophy are similarly bound up with it. These accounts vary extraordinarily, all the way from Polin's confident assertion that ‘ pour qui sait lire entre les lignes, … c'est ľatheísme qui triomphe implicitement ’, to Taylor's (...) equally firm belief that ‘a certain kind of theism is necessary to make [Hobbes's] theory work.’ 1 And now the latest of the Taylorians, Prof. Howard Warrender, has published his book The Political Philosophy of Hobbes , in which Hobbes's statements regarding the place of God are again treated as an essential part of his theory; and the charge explicitly made, that there are no sound grounds for regarding them as ‘the product of confusion or pretence on Hobbes's part’.

I am grateful for Mr Bagger's thoughtful remarks, as well as those of Professors Cousins, Smith, Katz, and Gimello at a recent American Academy of Religion panel devoted to The Problem of Pure Consciousness . But I cannot help but be struck by the tone of Mr Bagger's notice. As one colleague communicated to me after reading the piece, this is one of the most gratuitously rude pieces he had ever seen! If our book is really as bad as all (...) this, it makes one wonder why Religious Studies , or Mr Bagger, would bother to give it such attention, and whether it indicates how deeply we have touched a nerve in the contemporary debate.

The Black Mirror episode “Arkangel” tells a disturbing story of over-parenting driven by technology. The single mother Marie’s adoption of the Arkangel system has invited overwhelmingly negative moral evaluation from philosophers. But what accounts for the moral failure of a loving and concerned parent? Is it all about her flawed character, or are there situational factors at work? In the article, I first foreground the slipperiness of technology implicated in Albert Borgmann’s notion of the “device paradigm” and Hans Jonas’s analysis (...) of modern technology. Then I analyze the character of the Arkangel system in the light of the two philosophers’ works and show how the technology turns Marie into a failing parent. In the end, I offer tentative answers to the two questions; the answers shall also shed light on the problem of under-parenting driven by digital technology. (shrink)

Resource allocation is a central part of the decision-making process in any health care system. Resources have always been finite, thus the ethical issues raised are not new. The debate is now more open, and there is greater public awareness of the issues. It is increasingly recognised that it is the technology which determines resources. The ethical issues involved are often conflicting and relate to issues of individual rights and community benefits. One central feature of resource allocation is the basing (...) of decisions on the outcomes of health care and on their subsequent economic evaluation. The knowledge base is therefore of great importance as is the audit of results of clinical treatment. Public involvement is seen as an integral part of this process. For all parts of the process, better methodologies are required. (shrink)

The hypothesis that values change and evolve is examined by this paper. The discussion is based on a series of examples where, over a period of a few decades, new ethical issues have arisen and values have changed. From this analysis it is suggested that there are a series of core values around which most people would agree. These are unlikely to change over long time periods. There are then a series of secondary or derived values around which there is (...) much more controversy and within which differences of view occur. Such changes need to be documented if we are to understand the process involved in the evolution of differences in ethical views. (shrink)
