Early attempts at combining multiple inheritance with nonmonotonic reasoning were based on straightforward extensions of tree-structured inheritance systems, and were theoretically unsound. In The Mathcmat~'cs of Inheritance Systcrns, or TMOIS, Touretzky described two problems these systems cannot handle: reasoning in the presence of true but redundant assertions, and coping with ambiguity. TMOIS provided a definition and analysis of a theoretically sound multiple inheritance system, accom-.

In describing the flawless regularity of developmental processes and the correlation between changes at certain genetic loci and changes in morphology, biologists frequently employ two metaphors: that genes ‘control’ development, and that genomes embody ‘programs’ for development. Although these metaphors have an admirable sharpness and punch, they lead, when taken literally, to highly distorted pictures of developmental processes. A more balanced, and useful, view of the role of genes in development is that they act as suppliers of the material needs (...) of development and, in some instances, as context‐dependent catalysts of cellular changes, rather than as ‘controllers’ of developmental progress and direction. The consequences of adopting this alternative view of development are discussed. (shrink)

A new challenge for Bible translators A few decades ago the development of the dynamic-equivalent method of translation (which later became known as functional equivalence) broke radically away from the formal and traditional method of translation. Since then the functional-equivalent approach has undergone refinement, but the development can no longer be called revolutionary. However, research in the art of translation has now shifted from the method of translation to the format of the printed text (also called the paralinguistic features of (...) the text). In this article practical examples are given of how the employment of paralinguistic features can underscore the meaning of the text of the Bible, especially the Afrikaans Bible since it has become imperative to start working on a new translation.

Purpose: This conceptual-epistemological paper deals with the old problem of inversion of thinking, as typified by traditional metaphysics-ontology. It is proposed that a thorough constructivism -- which views structures of mind, nature, and all, as not derived from (not referring to) any pre-structured given mind-independent reality (zero-derivation, 0-D) -- can go beyond this conceptual impasse; it can also serve as a fall-back position for positive ontologies. Practical implications: The practical result of 0-D is that all structures of experience are understood (...) as tools serving individual and collective subjects. Conclusion: This conceptual correction results in a simplification for the understanding of some conceptual puzzles, such as the mind-brain relation, but also in a considerable increase of responsibility, because entities and agents formerly considered responsible, and outside the mind, are recognized to be extensions of the subjects.

The present work is intended once again to draw the attention of readers to the resources opened up by Spinoza for the elucidation of the classical problems of philosophy. Today these problems are too often taken to be merely verbal, so that answers to them so far as these are metaphysical are confidently claimed to be "nonsense. " My labours will, therefore, seem to minds thus committed to have been untimely and funda mentally futile. Untimely they may have been, but (...) unless also fu tile their untimeliness may render them the more exigent; and to judge them as futile is to claim a certainty not avaIlable to the honest sceptic. Vigorous attempts to discredit metaphysical investigation are no new thing, though the latest is, perhaps, the most thoroughgoing, and cer tainly the most self-confident. Yet it may well be argued that effective criticism of metaphysics is either itself a sort of metaphysics, or has for its foundation presuppositions that could only be metaphysically es tablished. "Naturam expellas furca, tamen usque recurret. " Metaphysics survives, and can only survive as a true philosophia perennis, as the catalyst of scepsis and schism - neither as inexorabie dogma "once for all de livered," nor as "a plant that cometh of the lust of the earth, without a formal seed.
