Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the (...) underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured. (shrink)

Central to Elements is an assay of the attributional union properties and relations have with their subjects, a topic historically left metaphorical. The work critiques eight Aristotelian assumptions concerning attribute dependence and ‘inherence’, per se subjects, attributes as agent-organizers, and unity-by-a-shared-one. Groups of these assumptions are seen to yield contradiction, vicious regress, or other problems. This analysis, joined with insights from an assay of ubiquitous structure, motivate ten theses explicating attribution and its primary ontic status. The theses detail: attributes proper (...) as individuated instances, structure as instance-generated facts and their two forms of composition, the conditioning role and universal nature of instances’ component intensions, the primacy of attribute instances for generating all forms of composition and complex entities, and identity and indiscernibility criteria for the latter. Principal is the insight that attribution is intension-determined combinatorial agency. It is its systematizing implications that provide solutions to classic problems, e.g., Composition, Individuation, and Universals, and in net generate a comprehensive one-category structuralist ontology.

In a recent article [Mertz 2001] in this journal I argued for the virtues of a realist ontology of relation instances (unit attributes). A major strength of this ontology is an assay of ontic ('material') predication that yields an account of individuation without the necessity of positing and defending 'bare particulars'. The crucial insight is that it is the unifying agency or combinatorial aspect of a relation instance as predicable that is for ontology the principium individuationis [Mertz 2002; 1996]. Or (...) in short, what is ontically predicable, precisely as such, is the cause of individuation. As a preface to this positive doctrine I offered arguments against the coherence of bare particulars as defended in an article by J. P. Moreland [1998]. In a reply contained in this issue Moreland and Timothy Pickavance (hereafter M/P) propose to answer my objections [2002]. The response that follows provides reasons why, I contend, M/P have not succeeded in parrying my objections to bare particulars. (shrink)

Social scientists could learn some useful things from philosophy. Here I shall discuss what I take to be one such thing: a better understanding of the concept of utility. There are several reasons why a better understanding may be useful. First, this concept is commonly found in the writings of social scientists, especially economists. Second, utility is the main ingredient in utilitarianism, a perspective on morality that, traditionally, has been very influential among social scientists. Third, and most important, with a (...) better understanding of utility comes, as I shall try to show here, a better understanding of “personal welfare”. or, in other words, of what may be said to be in people's best interests. Such an understanding is useful to social scientists and philosophers alike, whether for utilitarian purposes or not. (shrink)

Is it possible to do something intentionally and yet be unconscious of so doing? Many philosophers would answer ‘No’ to this question on the grounds that it is of the essence of intention that if we do something intentionally we do it knowing what we are doing.

Galileo's refutation of the speed-distance law of fall in his Two New Sciences is routinely dismissed as a moment of confused argumentation. We urge that Galileo's argument correctly identified why the speed-distance law is untenable, failing only in its very last step. Using an ingenious combination of scaling and self-similarity arguments, Galileo found correctly that bodies, falling from rest according to this law, fall all distances in equal times. What he failed to recognize in the last step is that this (...) time is infinite, the result of an exponential dependence of distance on time. Instead, Galileo conflated it with the other motion that satisfies this ‘equal time’ property, instantaneous motion. (shrink)

The empiricism of eighteenth-century experimental science meant that the development of scientific instruments influenced the formulation of new concepts; a two-way process for new theory also affected instrument design. This relationship between concept and instrumentation will be examined by tracing the development of electrical instruments and theory during this period. The different functions fulfilled by these devices will also be discussed. Empiricism was especially important in such a new field of research as electricity, for it gave rise to phenomena that (...) could not have been predicted by theory alone. However, the interpretation of these phenomena, and what the natural philosopher thought he observed, were often unconsciously determined by current ideas and attitudes; the interaction between instrumentally induced phenomena and observation was more complex than was realized at the time. The shortcomings of this empirical approach will be discussed. In the case of electricity this became increasingly apparent during the latter part of the century. The many discoveries had to be placed in a unifying framework before new advances could be made. Instruments, however, continued to play an important role in scientific progress, for they made visible what was hidden in nature. (shrink)

SummaryThis report describes a family planning KAP survey conducted in 2000 households in rural Ghana between April and October, 1972, as one of the Danfa Project’s baseline studies. Subsequent re-surveys were done in 1975 and 1977 to assess changes related to project health education and family planning programmes.Reported knowledge about family planning was three times that reported in previous studies in rural Ghana. About 70% of the respondents approve of family planning, but most want a large family, with over six (...) children. At all ages, males wanted two or three more children than did women.The current 3% population growth rate in Ghana may increase due to continued early age of marriage, the rising size of the reproductive age group and improved pregnancy outcome.Although the expected relationships between knowledge and use of family planning and age and education were present, these differentials were typically only 10–15%. In the project area it appears that women will be most important in making the decision to practise family planning, although motivation of males is being stressed.Most villagers hear about family planning through informal, word-of-mouth channels with relatively little use of news media, family planning workers or clinic health personnel. To improve the practice of family planning, village-based health educators are working with volunteers including traditional birth attendants, community leaders, teachers and church groups. (shrink)

An ontology's theory of ontic predication has implications for the concomitant predicate logic. Remarkable in its analytic power for both ontology and logic is the here developed Particularized Predicate Logic (PPL), the logic inherent in the realist version of the doctrine of unit or individuated predicates. PPL, as axiomatized and proven consistent below, is a three-sorted impredicative intensional logic with identity, having variables ranging over individuals x, intensions R, and instances of intensions $R_{i}$ . The power of PPL is illustrated (...) by its clarification of the self-referential nature of impredicative definitions and its distinguishing between legitimate and illegitimate forms. With a wellmotivated refinement on the axiom of comprehension, PPL is, in effect, a higher-order logic without a forced stratification of predicates into types or the use of other ad hoc restrictions. The Russell-Priest characterization of the classic self-referential paradoxes is used to show how PPL diagnosis and solves these antimonies. A direct application of PPL is made to Grelling's Paradox. Also shown is how PPL can distinguish between identity and indiscernibility. (shrink)

The existing model for ethical review of medical research consists primarily of regulations designed to prevent exploitation of participants. This model may fail when reviewing other ethical obligations, particularly the responsibility to provide valuable knowledge to society. Such failure is most apparent in developing countries, in which many stakeholders lack incentives or power to uphold society’s interests. An alternative ethical model is that of partnership, which actively involves all partners during ethical review and aims to secure partners’ best interests through (...) compromise. Unlike the existing “regulatory” model, the partnership model effectively addresses ethical obligations to provide positive benefits to society. For the partnership model to be effective, power must be shared among partners; thus, the partnership model can be harmonised with the “regulatory” model through explicit consideration of power structures. One opportunity for crafting power balance in developing countries is apparent in “implementation trials”—randomised trials motivated by and integrated into the implementation of long term public health interventions. Given the failings of the existing ethical review model, alternative models—for example, partnership—and means to balance power—for example, implementation trials—must be explored to ensure that medical research provides knowledge of value to societies in the developing world.

1. Aim and Scope of this Paper.—In this paper I shall try to show that “duty” derives its significance from its relation to “interest,” and that the former concept cannot be understood when taken apart from its relation to the latter. Such a doctrine is, I am aware, rejected by some contemporary philosophers; and I shall, I trust, make it sufficiently clear in the sequel why I am unable to accept their view.I am not, however, concerned primarily with criticism of (...) other theories. This paper represents an attempt to interpret a particular province of “the common moral consciousness” and to elicit the principles there implied. I begin by accepting the view that, like natural science, ethics has its data, and that it is the business of ethics to interpret these data which are the contents of the “moral consciousness.” In Section A I discuss various methods which may be used for the discovery of the relevant data, and suggest that initial enquiries can most fruitfully be pursued in the field of law and custom. In Section B I undertake an analysis of the principles of the law relating to promise-keeping. As a result of what is there found, it becomes necessary, in Section C, to discuss the nature of rights and their relation to interests, and, in Section D, the nature of duties and their relation to rights.

You have invited me to speak about Morals without Faith . Briefly, I take it, this question means: is there any moral law for agnostics? But it might be more interesting to put it rather differently: to ask, not simply whether there is a moral law for those who do not believe in God, but whether there is any such law even for those who do independent of their belief? We are then asking: Does being under a moral law mean (...) nothing more than being commanded by God? Is the only incentive for obeying it in our love or fear of Him, the only criterion by which to judge the morality of actions in their conformity to a revealed standard? Or would it be more true to say that the law which God wishes us to obey is that law to which we ought to conform because it corresponds to our nature and conditions in this world, a law which, apart from being God's will, we can understand as being indispensable to the kind of beings we are?

Butler observes in the Preface to the Sermons that the subject of morals can be approached in two different ways: “One begins from enquiring into the abstract relations of things: the other from a matter of fact, namely what the particular nature of man is, its several parts, their economy or constitution; from whence it proceeds to determine what course of life it is, which is correspondent to his whole nature. In the former method the conclusion is expressed thus, that (...) vice is contrary to the nature and reason of things: in the latter, that it is a violation or breaking in upon our own nature. Thus they both lead us to the same thing, our obligations to the practice of virtue; and thus they exceedingly strengthen and enforce each other.” In making this observation Butler raises the problem of the nature of moral obligation, and of the criteria by which the existence of a moral obligation can be known. He does so by calling attention to the divisions of opinion which existed on this issue in his own days. Samuel Clarke, the fashionable moralist of the period, sought the roots of moral obligation in the “nature and reason of things”: for an agent to know that an act is his duty is to know that it is fitting or suitable to the circumstances in which it occurs . Shaftesbury, on the other hand, and many of the adherents to the doctrine of Natural Law, like Grotius and Pufendorf, sought the roots of moral obligation in the nature of agents: for an agent, to know that an act is his duty is for him to experience a special motive to do it . Butler recognized the fundamental difference between these two approaches. (shrink)

In this paper I shall explain what I take to be the nature of justice; and the method which I shall follow is that of attempting to infer the essential nature of justice from an examination of its actual practical operation. Perhaps the reader will be able to follow the drift of the argument more easily, and be more on his guard against possible misstatements of fact or erroneous inferences, if I mention at the outset the main conclusions to which (...) I hope to lead him. (shrink)

In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or external design.Self-directedness (...) lies at the nexus of issues concerning the evolution and nature of intentionality, intelligence, and agency. It provides some insight into the evolution of intelligence because it helps explain how organisms are able to manage variable interaction processes, e.g., a hunting strategy that varies with prey type, ground condition, and hunger level. Simple self-directed organisms like bumblebees manage variability in one or a few dimensions. (shrink)

“Nation” and “nationalism” are not easily defined; mainly, perhaps, because these words, as popularly used, do not have precise meanings. A nation may mean: A people living under a common government,—as when we speak of British or French “nationals"; or A people with a common racial inheritance—the Jews; or A people, inhabiting a certain tract of the earth's surface, with generally common sentiments and habits of thinking, though possibly of mixed race, and part of a wider political society—the English, as (...) distinguished from the Scottish, or Irish, nation.

The question of punishment is one which has always interested and usually puzzled moralists, and which forms a crucial example for the testing of moral theories. A utilitarian theory, whether of the hedonistic or of the ‘ ideal ’ kind, if it justifies punishment at all, is bound to justify it solely on the ground of the effects it produces. The suffering of pain by the person who is punished is thought to be in itself a bad thing, and the (...) bringing of this bad thing into the world is held to need justification, and to receive it only from the fact that the effects are likely to be so much better than those that would follow from his non-punishment as to outweigh the evil of the pain.
