Properties sometimes attributed to the “particle” aspect of a neutron, e.g., mass and magnetic moment, cannot straightforwardly be regarded in the Bohm interpretation of quantum mechanics as localized at the hypothetical position of the particle. This is shown by examining a series of effects in neutron interferometry. A related thought-experiment also provides a variation of a recent demonstration that which-way detectors can appear to behave anomolously in the Bohm theory.

In "Realism and Reason" Hilary Putnam has offered an apparently strong argument that the position of metaphysical realism provides an incoherent model of the relation of a correct scientific theory to the world. However, although Putnam's attack upon the notion of the "intended" interpretation of a scientific theory is sound, it is shown here that realism may be formulated in such a way that the realist need make no appeal to any "intended" interpretation of such a theory. Consequently, it can (...) be shown that realism is immune to Putnam's criticism and that attempts at reformulating this criticism are not likely to meet with success. (shrink)

Explaining the persistence of populations is an important quest in ecology, and is a modern manifestation of the balance of nature metaphor. Increasingly, however, ecologists see populations (and ecological systems generally) as not being in equilibrium or balance. The portrayal of ecological systems as “non-equilibrium” is seen as a strong alternative to deterministic or equilibrium ecology, but this approach fails to provide much theoretical or practical guidance, and warrants formalisation at a more fundamental level. This is available in adaptation theory, (...) which allows population persistence to be explained as an epiphenomenon stemming from the maintenance, survival, movement and reproduction of individual organisms. These processes take place within a physicochemical and biotic environment that persists through structured annual cycles, but which is also spatiotemporally dynamic and subject to stochastic variation. The focus is thus shifted from the overproduction of offspring and the consequent density dependent population pressure thought to follow, to the adaptations and ecological circumstances that support those relatively few individuals that do survive.

G H Bantock; The Parochialism of the Present: some reflections on the history of educational theory, Journal of Philosophy of Education, Volume 13, Issue 1, 30.

A model for the ideal state includes discussions of the nature and application of justice, the role of the philosopher in society, the goals of education, and the effects of art upon character.

At first sight, the philosophy of Spinoza may seem wholly alien to what is now generally regarded as philosophy in the English-speaking world. For some decades, the dominant trend in that philosophy has been linguistic and anti-metaphysical; the philosopher is held to be concerned with the analysis of language, and not with speculative system-building. Spinoza, on the other hand, is very much a system-builder; as to the analysis of language, he says explicitly that this is of no interest to him. (...) ‘It is not my intention’, he says, ‘to explain the meanings of words; it is my intention to explain the nature of things’. However, the paper which follows will attempt to show that Spinoza’s philosophy is not wholly without relevance today. It will try to do this by placing one of Spinoza’s most important doctrines, his theory of human freedom, within the context of recent discussions. (shrink)
