Following a previous article published in Biological Theory, in this study we present a mathematical theory for a science of qualities as directly perceived by living organisms, and based on morphological patterns. We address a range of qualitative phenomena as observables of a psychological system seen as an impredicative system. The starting point of our study is the notion that perceptual phenomena are projections of underlying invariants, objects that remain unchanged when transformations of a certain class under consideration are applied. (...) The study develops with the observables, the entailed total order and metric, whence the algebra and the geometry of such a science, presenting a formal phenomenological model for phenomena that are not rigidly Euclidean. We show how non-Euclidean perception can have many useful Euclidean formalizations, as well as locally-homeomorphic-to-Euclidean-space models. The mathematical models we provide are tested on the basis of results from experimental psychology, in particular from the field of color, time, and space perception. (shrink)

The concern for ethical principles and values is not limited to health professionals alone. However, ethical principles in nursing act as safety valves for social control to prevent professional misconduct and abuse of the rights of clients. As a result of colonial experience, developing countries like Botswana usually follow the European lead, especially examples from the UK. This article examines the ethical problems and dilemmas associated with rural nursing practice in Botswana, a developing country in sub-Saharan Africa. The major ethical (...) problems identified are related to the distribution of and access to health resources in rural communities. It is proposed that nurses must assume responsibility in the field of access and allocation by working collaboratively with governments and other professional bodies, and that nurses as a global community must work together as a team to support each other.

I comment on the preceding essays in this current thematic issue of Axiomathes , essays that discuss my 2009 book More Than Life Itself: A Synthetic Continuation in Relation Biology.

In the Classical Quarterly for April, 1933, Professor Cornford maintains that the ‘Two Ways’ of Parmenides are not meant as alternatives: ‘The Way of Truth and the Way of Seeming are no more parallel and alternative systems of cosmology, each complete in itself, than are Plato's accounts of the intellectual and sensible worlds.’ I wish here to try to support his general view, which seems to me to be indisputably correct, while differing from Professor Cornford in some important details.
