Revised and reprinted in Handbook of Philosophical Logic, volume 10, Dov Gabbay and Frans Guenthner (eds.), Dordrecht: Kluwer, (2003). -- Two sorts of property theory are distinguished, those dealing with intensional contexts property abstracts (infinitive and gerundive phrases) and proposition abstracts (‘that’-clauses) and those dealing with predication (or instantiation) relations. The first is deemed to be epistemologically more primary, for “the argument from intensional logic” is perhaps the best argument for the existence of properties. This argument is presented in the (...) course of discussing generality, quantifying-in, learnability, referential semantics, nominalism, conceptualism, realism, type-freedom, the first-order/higher-order controversy, names, indexicals, descriptions, Mates’ puzzle, and the paradox of analysis. Two first-order intensional logics are then formulated. Finally, fixed-point type-free theories of predication are discussed, especially their relation to the question whether properties may be identified with propositional functions. (shrink)

Conservation biologists and other environmentalists confront five obstacles in building support for regulatory policies that seek to exclude or remove introduced plants and other non-native species that threaten to harm natural areas or the natural environment. First, the concept of “harm to the natural environment” is nebulous and undefined. Second, ecologists cannot predict how introduced species will behave in natural ecosystems. If biologists cannot define “harm” or predict the behavior of introduced species, they must target all non-native species as potentially (...) “harmful”. an impossibly large regulatory task. Third, loss of species richness may constitute harm to an environment, but introduced organisms typically, generally, and significantly add to species richness in ecosystems. If species richness correlates with desirable ecosystem properties, moreover, such as stability and productivity, as some ecologists believe, then introduced organisms, by increasing species richness, would support those desirable properties. Fourth, one may plausibly argue that extinction constitutes environmental harm, but there is no evidence that non-native species, especially plants, are significant causes of extinction, except for predators in certain lakes and other small island-like environments. Fifth, while aesthetic, ethical, and spiritual values may provide a legitimate basis for invasive species policy, biologists often cite concepts such as “biodiversity” and ecosystem “health” or “integrity” to provide a scientific justification. To assert that non-native species threaten biodiversity or undermine ecosystem health, however, may be to draw conceptual entailments or consequences from definitions of “biodiversity” and “integrity” that arbitrarily exclude non-native species or make the presence of exotic species a per se indicator of decline.

In this paper I use the concept of forbidden knowledge to explore questions about putting limits on science. Science has generally been understood to seek and produce objective truth, and this understanding of science has grounded its claim to freedom of inquiry. What happens to decision making about science when this claim to objective, disinterested truth is rejected? There are two changes that must be made to update the idea of forbidden knowledge for modern science. The first is to shift (...) from presuming that decisions to constrain or even forbid knowledge can be made from a position of omniscience (perfect knowledge) to recognizing that such decisions made by human beings are made from a position of limited or partial knowledge. The second is to reject the idea that knowledge is objective and disinterested and accept that knowledge (even scientific knowledge) is interested. In particular, choices about what knowledge gets created are normative, value choices. When these two changes are made to the idea of forbidden knowledge, questions about limiting or forbidding lines of inquiry are shown to distract attention from the more important matters of who makes and how decisions are made about what knowledge is produced. Much more attention should be focused on choosing directions in science, and as this is done, the matter of whether constraints should be placed on science will fall into place. (shrink)

There are many uncertainties concerning climate change, but a rough international consensus has emerged that a doubling of atmospheric carbon dioxide from its pre-industrial baseline is likely to lead to a 2.5 degree centigrade increase in the earth's mean surface temperature by the middle of the next century. Such a warming would have diverse impacts on human activities and would likely be catastrophic for many plants and nonhuman animals. The author's contention is that the problems engendered by the possibility of (...) climate change are not purely scientific but also concern how we ought to live and how humans should relate to each other and to the rest of nature; and these are problems of ethics and politics.

Dialectic of Enlightenment is undoubtedly the most influential publication of the Frankfurt School of Critical Theory. Written during the Second World War and circulated privately, it appeared in a printed edition in Amsterdam in 1947. "What we had set out to do," the authors write in the Preface, "was nothing less than to explain why humanity, instead of entering a truly human state, is sinking into a new kind of barbarism." Yet the work goes far beyond a mere critique of (...) contemporary events. Historically remote developments, indeed, the birth of Western history and of subjectivity itself out of the struggle against natural forces, as represented in myths, are connected in a wide arch to the most threatening experiences of the present. The book consists in five chapters, at first glance unconnected, together with a number of shorter notes. The various analyses concern such phenomena as the detachment of science from practical life, formalized morality, the manipulative nature of entertainment culture, and a paranoid behavioral structure, expressed in aggressive anti-Semitism, that marks the limits of enlightenment. The authors perceive a common element in these phenomena, the tendency toward self-destruction of the guiding criteria inherent in enlightenment thought from the beginning. Using historical analyses to elucidate the present, they show, against the background of a prehistory of subjectivity, why the National Socialist terror was not an aberration of modern history but was rooted deeply in the fundamental characteristics of Western civilization. Adorno and Horkheimer see the self-destruction of Western reason as grounded in a historical and fateful dialectic between the domination of external nature and society. They trace enlightenment, which split these spheres apart, back to its mythical roots. Enlightenment and myth, therefore, are not irreconcilable opposites, but dialectically mediated qualities of both real and intellectual life. "Myth is already enlightenment, and enlightenment reverts to mythology." This paradox is the fundamental thesis of the book. This new translation, based on the text in the complete edition of the works of Max Horkheimer, contains textual variants, commentary upon them, and an editorial discussion of the position of this work in the development of Critical Theory.

Offers a philosophical exploration of the pervasiveness of place. Presenting an account of the role of place in human experience, this book points to place's indispensability in navigation and orientation. The role of the lived body in matters of place isconsidered, and the characteristics of built places are explored.

Environmental ethics is the discipline in philosophy that studies the moral relationship of human beings to, and also the value and moral status of, the environment and its nonhuman contents. This entry covers: (1) the challenge of environmental ethics to the anthropocentrism (i.e., humancenteredness) embedded in traditional western ethical thinking; (2) the early development of the discipline in the 1960s and 1970s; (3) the connection of deep ecology, feminist environmental ethics, and social ecology to politics; (4) the attempt to apply (...) traditional ethical theories, including consequentialism, deontology, and virtue ethics, to support contemporary environmental concerns; and (5) the focus of environmental literature on wilderness, and possible future developments of the discipline.

Over the last few years, the public has gradually become aware of the existence of a new cause: animal liberation. Most people first heard of the movement through newspaper articles, often of the "what on earth will they come up with next?" variety. Then there were marches and demonstrations against factory farming, animal experimentation or the Canadian seal slaughter; all brought to an audience of millions by the TV cameras. Finally there have been the illegal acts: slogans daubed on fur (...) shops, laboratories broken into and animals rescued. What are the ideas behind the animal liberation movement, and where is it heading? In this essay I shall try to answer these questions. (shrink)

An extraordinary development of the central nervous system distinguishes Homo sapiens from all other biological species and has bestowed upon him the ability to grossly alter the structure and function of natural systems to such an extent that the biosphere – a sphere of all living organisms – is now virtually transformed into the ‘noosphere’ – a world controlled by the mind of man. Thus, more than the legal or technological tools, it is the human mind that ultimately holds the (...) key to the conservation of the biosphere or its possible destruction. Hence, the ethical positions adopted by man in his dealings with nature are important determinants of the fate of the biosphere, including that of the human species itself. Such ethical positions may be ‘anthropocentric’, where conservation is human-centred and no other component is assigned any intrinsic value, or they may be ‘biocentric’/ ‘ecocentric’ to varying degrees, where intrinsic value is recognized in other organisms or in the ecosystems as well. Against the backdrop of these ethical positions, we analyze in this paper the myths and folklores, as well as cultural beliefs, customs and practices of indigenous communities of Northeastern India such as tribals, fisherfolk, hunter-trappers, plantation workers, farmers and so forth, and attempt to trace the ethical basis of various resource utilization and conservation strategies adopted by them. The present-day threats and pressures leading to an erosion of these traditional value-systems are also described and discussed. (shrink)
