James V. Neel, one of the leading human geneticists of the 21st Century, has long been concerned about the consequences of human overpopulation and the accompanying destruction of the earth's ecosystem. His point of view, summarized in this paper, is contrasted with some recent optimistic projections presented by demographers and population biologists who believe the population bomb has been defused by evidence of a decrease in worldwide fertility along with a significant increase in food production. The authors of this paper (...) are not so optimistic and see a continuing need for concern rather than complacency based on ever increasing human wants and aspirations together with the minimal results of recent environmental summits. The case of HIV/aids is used to illustrate the evolutionary implications of the interaction between population dynamics and genetic change based on the concepts of population bottlenecks, genetic drift and founder effects. What becomes evident from this illustration is that epidemics by viral and other pathogens in the 21st Century can affect the size of human populations and thereby the course of the species' evolutionary makeup. The potential of evolutionary medicine and in particular molecular biology to improve our prediction capabilities and modulate some of the possible consequences is discussed. (shrink)

The growth of knowledge and its effects on the practice of medicine have been issues of philosophical and ethical interest for several decades and will remain so for many years to come. The outline of the present volume was conceived nearly three years ago. In 1987, a conference on this theme was held in Maastricht, the Netherlands, on the occasion of the founding of the European Society for Philosophy of Medicine and Health Care (ESPMH). Most of the chapters of this (...) book are derived from papers presented at that meeting, and for the purpose of editing the book Stuart Spicker, Ph. D., joined two founding members of ESPMH, Henk ten Have and Gerrit Kimsma. The three of them successfully brought together a number of interesting contribu tions to the theme, and ESPMH is grateful and proud to have initiated the production of this volume. The Society intends that annual meetings be held in different European countries on a rotating basis and to publish volumes related to these meetings whenever feasible. In 1988, the second conference was held in Aarhus, Denmark on "Values in Medical Decision Making and Resource Allocation in Health Care". In 1989, a meeting was held in Czestochowa, Poland, on "European Traditions in Philosophy of Medicine. From Brentano to Bieganski". It is hoped that these conferences and the books to be derived from them, will initiate a new European tradition, lasting well into the 21 st century! P. J. (shrink)

I. Introduction Hegel's political philosophy is best understood as being both moderate and critical in character. While the recent scholarship is partially correct in its “centrist-reformist” image of Hegel's political philosophy, I argue that this image is incomplete. Hegel's project in the Philosophy of Right is moderate in the respect that it is a defense of his conceptualization of the modern state—it is the attempt to make explicit the implicit rationality of the modern state form. But his prescient critique of (...) the intractable contradictions of the open capitalist market and his identification of civil society with…. (shrink)

David Lewis's modal realism claims that nothing can exist in more than one world or time, and that statements about how something would have been are to be analysed in terms of its counterpart. I first explain why the counterpart relation depends on de re modal statements in an intensional language, so that intuitive properties of similarity relations cannot be used to show that the counterpart relation is not an equivalence relation. I then look at test sentences in (the intensional) (...) natural language, and show that none of them provide compelling evidence that a counterpart semantics is needed. (shrink)

It is suggested that the anatomical structures whichmediate consciousness evolved as decisiveembellishments to a (non-conscious) design strategypresent even in the simplest monocellular organisms.Consciousness is thus not the pinnacle of ahierarchy whose base is the primitive reflex, becausereflexes require a nervous system, which the monocelldoes not possess. By postulating that consciousness isintimately connected to self-paced probing of theenvironment, also prominent in prokaryotic behavior,one can make mammalian neuroanatomy amenable todramatically simple rationalization.

In this reply to Paul Simmons, it is argued that while biblical scripture should be understood as the Christian's first and final authority, it is appropriate to draw on other writings as sources for moral reflection. Responsible biblical interpretation and theological reflection must include careful historical analysis. It is inaccurate and anachronistic to read into early Jewish and Christian thinkers a position much like the reigning secular philosophical-legal position on abortion, where fetal non-personhood and individual freedom results in abortion without (...) legal constraints. Careful scholarship reveals that a theological community-based Christian ethic, which develops from first century reflections and biblical canonical authority, prohibits direct abortion as an option for the Christian community.

The chief sources of groundwater contamination on farms come from point sources and diffuse sources. Possible point sources are feedlots, poorly-sited manure piles, septic sewage-treatment systems—all of which can release nitrate, phosphates and bacteria— and sites of chemical spills. Diffuse sources are typified by excess fertilizer leaching from a number of arable fields. The basis of quality standards for drinking-water is discussed in relation to common contaminants present on farms. Samples of drinking-water were collected in 1991–1992 from wells on about (...) 1,200 farms in order to study the quality of rural groundwater in Ontario. Analysis showed that approximately one third of wells were contaminated with bacteria, 14% were contaminated with nitrate, two wells were contaminated with pesticide, but 40% were considered unsafe because of the presence of at least one contaminant. These values were similar to those reported for similar regions in the U.S. There was no significant effect of agricultural practice on the proportion of contaminated samples. One response of Ontario's farmers to information on water quality has been to initiate their own program, the Environmental Farm Plan, which has 23 modules by which the risk of environmental contamination can be assessed. Government policies for agriculture can be expected to influence farming practices. However, the literature suggests that the consequences of policies aimed at reducing environmental contamination are poorly understood, not least because the instruments used for implementation can have widely differing impacts. The need for discussions on the ethics surrounding the relationship between food producers and consumers with regard to environmental contamination is identified. (shrink)

Expressions in a language, whether words, phrases, or sentences, have meanings. So it seems reasonable to suppose that there are meanings that expressions have. Of course, it is fashionable in some philosophical circles to deny this.
