Richard Gale and Alexander Pruss raise a number of excellent questions in their separate responses to my comments on Gale’s book, On the Nature and Existence of God. They focus on aspects of my discussion that need at least to be clarified, if not retracted, in ways I explain in this reply.

John F. Post argues that physicalistic materialism is compatible with a number of views often deemed incompatible with it, such as the objectivity of values, the irreducibility of subjective experience, the power of the metaphor, the normativity of meaning, and even theism.

New-wave psychoneural reduction, a la Bickle and Churchland, conflicts with the way certain adaptation properties are individuated according to evolutionary biology. Such properties cannot be reduced to physical properties of the token items that have the adaptation properties. The New Wave may entail a form of individualism inconsistent with evolutionary biology. All of this causes serious trouble as well for Jaegwon Kim's thesis of the Causal Individuation of Kinds, his Weak Supervenience thesis, Alexander's Dictum, his synchronicity thesis that all psychological (...) kinds supervene on the contemporaneous physical states of the organism, Correlation Thesis, and indeed his Restricted Correlation Thesis. All these theses are strongly individualist, in the sense of entailing that ALL a thing's properties are determined by its own physical properties and relations, contrary to many properties in biology and psychology.

The method in question is conceptual analysis. The madness comes of its privileging received usage over theories that would revise our concepts so as to conform to the phenomena, not the other way around. The alternatives to capture-the-concept include revisionary theory-construction as practiced not only in the sciences but in some philosophies. I present a revisionary theory of an important kind of normativity -- the normativity involved in a biological adaptation's being for this or that -- which theory, I argue, (...) undermines the received objections to there being any such normativity objectively in the world. So too for other kinds of normativity, including the moral, insofar as the objections to their objectivity have the same form and presuppositions. (shrink)

The technology required for tissue-engineering food is the same as for medical applications, and in fact is derived from it. There are major differences in the implementation of those technologies, primarily related to the enormous scale required for food production and the different economical framework. In addition, the emotional context of food tissue engineering is also more complex than for medical applications. On the other hand, the tissues that are generated do not need to integrate in the body, with less (...) risk of adverse effects in the event of incomplete functional, neuronal or humoral adaptation. The implementation of tissue engineering for food is still in its infancy. No products exist yet. It will be extremely challenging to make these products a reality for the consumer, but the reward and return in terms of value for our society will be tremendous. (shrink)

Of the many topics worthy of discussion regarding older adults and bioethics, two seem to provide an especially pointed opportunity for reflection on our aging society. First, is aging itself something that biomedical researchers should focus on as a deficit to be overcome through eventual anti-aging treatments? While aging may not fall neatly into the disease category, it is clearly the primary susceptibility factor for the innumerable diseases of older adults, and therefore its potential deceleration consistent with the compression of (...) morbidity might constitute a salutary biomedical goal. The aging society is no panacea to those who suffer from a host of chronic illnesses and feel overwhelmed by the burden of years. Second, we must concentrate on the most challenging problematic of our current aging society, assuming that anti-aging technologies will only become available in future decades. One immense problem is the harsh reality of irreversible progressive dementia, which will serve here as an example of the rise of chronic illness, for which age itself is the primary risk factor.

They say it can't be done . You can't use language to get outside language . The very idea . Thus Putnam : "our language cannot be divided up into two parts, a part that describes the world `as it is anyway,' and a part that describes our conceptual contribution," in order..

The human life span has been extended considerably, and among the very old, women outnumber men by a large margin. Thus, the aging society cannot be adequately addressed without taking into account the experience of women in specific. This article focuses on women as caregivers for aging parents. It critically assesses what some women philosophers are saying about the basis and limits of these caregiving duties.

Ecologists traditionally regard time as part of the background against which ecological interactions play out. In this book, Eric Post argues that time should be treated as a resource used by organisms for growth, maintenance, and offspring production. Post uses insights from phenology -- the study of the timing of life-cycle events -- to present a theoretical framework of time in ecology that casts long-standing observations in the field in an entirely new light. Combining conceptual models with field (...) data, he demonstrates how phenological advances, delays, and stasis, documented in an array of taxa, can all be viewed as adaptive components of an organism's strategic use of time. Post shows how the allocation of time by individual organisms to critical life history stages is not only a response to environmental cues but also an important driver of interactions at the population, species, and community levels. To demonstrate the applications of this exciting new conceptual framework, Time in Ecology uses meta-analyses of previous studies as well as Post's original data on the phenological dynamics of plants, caribou, and muskoxen in Greenland.--Back cover.

The concept of altruism, or disinterested concern for another's welfare, has been discussed by everyone from theologians to psychologists to biologists. In this book, evolutionary, neurological, developmental, psychological, social, cultural, and religious aspects of altruistic behavior are examined. It is a collaborative examination of one of humanity's essential and defining characteristics by renowned researchers from various disciplines. Their integrative dialogue illustrates that altruistic behavior is a significant mode of expression that can be studied by various scholarly methods and understood from (...) a variety of perspectives in both the humanities and the sciences. Altruism and Altruistic Love establishes a framework for scholarship on altruism by presenting definitions, a historical overview, a review of contemporary research, and debates in various disciplines, as well as a discussion of directions for future work.

Kottler, Cartan, and van Dantzig independently uncovered a key property of the Maxwell equations, which, in retrospect, is instrumental for treating noninertial situations. The essence of this KCD procedure is outlined. Present traditions incompatible with the KCD procedure are identified. KCD predicts a rotation-induced magnetoelectric effect in vacuum, as verified by the experiments of Kennard and Pegram. The description of nonvacuum situations still has some unresolved differences awaiting further experimental delineation. Explicit calculations and technical specifications of experiments receive references to (...) the literature. The emphasis of presentation stresses the conceptual reorganization necessary for lifting the Kennard-Pegram experiments out of their present state of obscurity. The question of whether or not KCD is a physically viable counterpart of the Lagrange-Hamilton-Jacobi procedure in mechanics is contingent on the outcome of more detailed experimentation of the Kennard-Pegram type.

Why did gender inequality in secondary school access persist after Mexico made attendance compulsory in 1993? This research reveals an interaction between geography, poverty, and sibship structure in contributing to the underrepresentation of girls in Mexico's poorer southern states. Using regional and contextual information about enrollments and development, a multinomial logistic regression model is estimated. The results show that in addition to family and regional poverty, the position of girls within the sibship contributes to their remaining in or dropping out (...) of school following the primary level and their likelihood of employment or domestic work as an alternative to schooling. The results have implications for Mexico's targeted approach to eliminating the effects of poverty on educational opportunity. (shrink)

To ask the question "Why does anything at all exist?" is equivalent to asking "What is the explanation of why anything at all exists." Thus the question presupposes that there is an explanation, known or unknown or unknowable, of why anything at all exists.

. In whatever form, terminal philosophy holds that some matters are so fundamental that they are presupposed in any practice of reason-giving; accordingly, if reason-giving were applied to such matters in order to justify them, or even to criticize, then the very attempt to do so would necessarily assume what is at issue, a fatal circularity . No further argumentative recourse is possible at this level of fundamentality ; rational reason-giving must terminate.

This article focuses on the elderly patient with a progressive and irreversible dementia, most often of the Alzheimer type. However dementia, the decline in mental function from a previous state, can occur in all ages. For example, if Alzheimer's disease is the dementia of the elderly, increasingly AIDS is the dementia of many who are relatively young. I will not present the major ethical issues relating to dementia care following the progression of disease from the mild to the severe stages, (...) for I have done this elsewhere. Among the issues included are: presymptomatic testing, both psychological and genetic; responsible diag- nostic disclosure and use of support groups; restrictions on driving and other activities; preemptive assisted suicide; advance directives for research and treatment; quality of life in relation to the use of life-extending technologies; and euthanasia.

American public law scholarship views law as a purposive instrument for the achievement of democratic purposes. It has analyzed how this instrument can best be employed within the historical context of the legal institutions and traditions of particular nation-states. Emerging forms of international law, articulated by international tribunals, challenge these fundamental premises of American public law scholarship. Much international law does not reflect the will of an indentifiable demos, and it is articulated through innovative legal institutions that combine the procedures (...) and organizational forms of many distinct states and legal cultures. Attempting to omprehend the sources and limitations of the legitimacy of this kind of international law will force American public law scholarship to re-examine deep and implicit presuppositions, inherited from legal realism, about the inherent normativity of the rule of law. The author speculates about possible effects of this re-examination on the substantive and methodological agenda of American public law scholarship. (shrink)
