Plato's geometrical theory of what we now call chemistry, set out in the Timaeus, uses triangles, his stoicheia, as the fundamental units with which he constructs his four elements. A paper claiming that these triangles can be divided indefinitely is criticized; the claim of an error here in the commentary by F.M. Cornford is unfounded. Plato's constructions of the elements are analyzed using simple point group theory. His procedure generates fully symmetric polyhedra, but Cornford's 'simpler' alternatives generate polyhedra with low (...) symmetries and multiple isomeric forms. However, Cornford's principle of constructing larger triangles by assembling smaller ones is still valid. (shrink)

That Jehovah's Witnesses cannot refuse life-saving blood transfusions on behalf of their children has acquired the status of virtual “consensus” among bioethicists. However strong the consensus may be on this matter, this article explores whether this view can be plausibly defended on liberal principles by examining it in light of one particularly well worked-out liberal political theory, that of Rawls. It concludes that because of the extremely high priority Rawls attributes to “freedom of conscience,” and the implication from the original (...) position that parents must act paternalistically toward their children as their protectors, Jehovah's Witnesses cannot legitimately be barred from making decisions on behalf of their children, even when the consequences of such decisions are serious and irremediable.

According to various accounts, intervention in pediatric decisions is justified either by the best interests standard or by the harm principle. While these principles have various nuances that distinguish them from each other, they are similar in the sense that both focus primarily on the features of parental decisions that justify intervention, rather than on the competency or authority of the parties that intervene. Accounts of these principles effectively suggest that intervention in pediatric decision making is warranted for both physicians (...) and the state under precisely the same circumstances. This essay argues that there are substantial differences in the competencies and authorities of physicians and the state, and that the principles that guide their interventions should also be conceived differently. While both the best interests standard and the harm principle effectively incorporate important aspects of physicians’ ethical obligations, neither adequately reflects the state’s ethical obligations. In contrast to physicians, the state has major obligations of distributive justice and neutrality that should form an integral part of any proposed ethical principles guiding state intervention in pediatric decision making. The differences are illustrated by examining recent cases involving parental refusal of chemotherapy in aboriginal Canadian communities and parental refusal of blood transfusions by Jehovah’s Witnesses.

Several commentators have tried to ground legal prohibitions of kidney sales in some form of Kant’s moral arguments against such sales. This paper reconsiders this approach to justifying laws and policies in light of Kant’s approach to law in his political philosophy. The author argues that Kant’s political philosophy requires that kidney sales be legally permitted, although contracts for such sales must remain unenforceable. The author further argues that Kant’s approach to laws, such as those governing kidney distribution, was formed (...) in part by considering and rejecting an assumption frequently employed in the bioethics literature, namely, that legal duties can be grounded directly in moral duties. The author explains some of Kant’s reasons for rejecting this assumption and concludes that arguments pertaining to the legality of kidney sales developed on the basis of Kant’s moral philosophy should no longer be considered tenable.

In Righting Health Policy, MacDougall argues that bioethics has not developed the tools best suited for justifying health law and policy. Using Kant’s practical philosophy as an example, he explores the promise of political philosophy for making normatively justified recommendations about health law and policy.

Bioethicists working on national ethics commissions frequently think of themselves as advisors to the government, but distance themselves from any claims to actual authority. Governments however may find it beneficial to appear to defer to the authority of these commissions when designing laws and policies, and might appoint such commissions for exactly this reason. Where does the authority for setting laws and policies come from? This question is best answered from within a normative political philosophy. This paper explains the locus (...) of moral authority as understood within one family of normative political theories—liberal political theories—and argues that most major “liberal” commentators have understood both the source and scope of ethics commissions’ authority in a manner at odds with liberalism, rightly interpreted. The author argues that reexamining the implications of liberalism for bioethics commissions would mean changing what are considered valid criticisms of such commissions and also changing the content of national bioethics commission mandates. The author concludes that bioethicists who participate in such commissions ought to carefully examine their own views about the normative limits of governmental authority because such limits have important implications for the contribution that bioethicists can legitimately make to government commissions.

There are a number of grounds for criticizing what the state requires of one, and for thinking that one no longer has an obligation to obey it. I will begin by attempting to locate liberalism amongst such grounds. It is useful for this purpose to contrast two headings under which these grounds may fall. Firstly, there are criticisms concerning the content of the requirements of the state. In this case exception is taken to what it is that the law requires (...) quite apart from the process by which it was arrived at. If Jews are legally prevented from practising certain professions, and objection is taken because no state should make laws debarring persons from certain professions on religious grounds, the objection is one of content. Secondly, there are grounds concerning the procedure by which a decision was reached. If it is thought that the British Government ought not to have signed the Treaty of Rome because no referendum was taken on whether the electorate wanted Britain to join, exception is taken to the procedure by which this decision was made. The objection could be made by one who thought that British entry was the best policy. liberalism lays down principles concerning the permissible content of what is required by the state. (shrink)

In this essay an ‘objective’ account of intrinsic value is proposed and partly defended. It is claimed that a kind of value exists which is, or may reasonably be supposed to be, a property of certain objects. The presence of such value is not to be wholly accounted for as the ‘projection’ of certain human feelings elicited by the object thought to be of value, nor by the object's meeting certain operative human conventions prescribing what is to be admired, nor (...) by its being conformable, in some way, to human needs or desires. Hume, of course, would have none of this. It is hoped to show that if one adopts Hume's account, then his attempt to show that there nevertheless will be convergence in the long run as to what is of aesthetic value is forced and unsuccessful. By contrast, on the ‘objective’ account convergence is to be expected. This, of course, only shows the superiority of the ‘objective’ account so long as there is an expectation of long-term convergence. This is not an expectation of most contemporary value ‘subjectivists’, and therefore the argument will not be directly relevant to their positions. (shrink)

During the last several decades, professional medicine has undergone profound changes in its organization. In particular, the growth of managed care organizations and publicly funded medicine has increasingly standardized physician working conditions and reimbursement. While it is sometimes disputed whether the profession of medicine is suffering reduced autonomy as a whole, there is little doubt that individual physicians are losing autonomy (Burdi and Baker 1999; Harrison and Schulz 1989; Iglehart 1992). As a result, physicians are increasingly attracted to various mechanisms (...) for retaining some control over their individual practice (Choudhry and Brennan 2001). Such mechanisms may include organization .. (shrink)

The ends of medicine are sometimes construed simply as promotion of health, treatment and prevention of disease, and alleviation of pain. Practitioners might agree that this simple formulation captures much of what medical practice is about. But while the ends of medicine may seem simple or even obvious, the essays in this issue demonstrate the wide variety of philosophical questions and issues associated with the ends of medicine. They raise questions about how to characterize terms like “health” and “disease”; whether (...) medicine’s goals should be extended to include enhancement beyond normal human function; and whether the ends of medicine are binding on those involved in health care outside of professional medicine, such as pharmaceutical companies. They also give philosophical attention to patient experiences, and so raise questions about whether current practices achieve the ends of medicine from the perspective of the patient. Together these essays demonstrate the important role played by a conception of medicine’s ends in a wide variety of issues and problems in the philosophy and ethics of medicine. (shrink)

Abstract:Bioethicists are sometimes thought to have heightened obligations by virtue of the fact that their professional role addresses ethics or morals. For this reason it has been argued that bioethicists ought to “whistleblow”—that is, publicly expose the wrongful or potentially harmful activities of their employer—more often than do other kinds of employees. This article argues that bioethicists do indeed have a heightened obligation to whistleblow, but not because bioethicists have heightened moral obligations in general. Rather, the special duties of bioethicists (...) to act as whistleblowers are best understood by examining the nature of the ethical dilemma typically encountered by private employees and showing why bioethicists do not encounter this dilemma in the same way. Whistleblowing is usually understood as a moral dilemma involving conflicting duties to two parties: the public and a private employer. However, this article argues that this way of understanding whistleblowing has the implication that professions whose members identify their employer as the public—such as government employees or public servants—cannot consider whistleblowing a moral dilemma, because obligations are ultimately owed to only one party: the public. The article contends that bioethicists—even when privately employed—are similar to government employees in the sense that they do not have obligations to defer to the judgments of those with private interests. Consequently, bioethicists may be considered to have a special duty to whistleblow, although for different reasons than those usually cited. (shrink)

One of six commentaries on “Obesity: Chasing an Elusive Epidemic,” by Daniel Callahan, from the January‐February 2013 issue.

Various U.S. laws, such as the Clean Air Act and the Food Quality Protection Act, require additional protections for susceptible subpopulations who face greater environmental health risks. The main ethical rationale for providing these protections is to ensure that environmental health risks are distributed fairly. In this article, we (1) consider how several influential theories of justice deal with issues related to the distribution of environmental health risks; (2) show that these theories often fail to provide specific guidance concerning policy (...) choices; and (3) argue that an approach to public decision making known as accountability for reasonableness can complement theories of justice in establishing acceptable environmental health risks for the general population and susceptible subpopulations. Since accountability for reasonableness focuses on the fairness of the decision-making process, not the outcome, it does not guarantee that susceptible subpopulations will receive a maximum level of protection, regardless of costs or other morally relevant considerations.

It first needs to be shown that this question raises a problem, for many people think it is answered, or at least dissolved, in the following way. There are two independent ways of answering the question “Why should I do X?”; one ultimately in terms of what I want to do, the other ultimately in terms of what I morally ought to do. Thus showing that I morally ought to do something is a final justification of a course of action. (...) No answer can be given to the further question “Given that X is what I morally ought to do, why ought I to do X?”. No further moral reasons can be given as ex hypothese the final moral reasons have already been given. As it is denied that moral reasons can be reduced to reasons in terms of what I want to do, the only other possible kind of reason has been ruled out also. This, however, is said net to matter, because moral reasons are not in need cf any further justification. Moral considerations simply are reasons for action just as much as wanting to do something simply is a reason for doing it. (shrink)

Legal standards of disclosure in a variety of jurisdictions require physicians to inform patients about the likely consequences of treatment, as a condition for obtaining the patient’s consent. Such a duty to inform is special insofar as extensive disclosure of risks and potential benefits is not usually a condition for obtaining consent in non-medical transactions. -/- What could morally justify the physician’s special legal duty to inform? I argue that existing justifications have tried but failed to ground such special duties (...) directly in basic and general rights, such as autonomy rights. As an alternative to such direct justifications, I develop an indirect justification of physicians’ special duties from an argument in Kant’s political philosophy. Kant argues that pre- legal rights to freedom are the source of a duty to form a state. The state has the authority to conclusively determine what counts as “consent” in various kinds of transactions. The Kantian account can subsequently indirectly justify at least one legal standard imposing a duty to inform, the reasonable person standard, but rules out one interpretation of a competitor, the subjective standard.

If the world were wholly just, the following inductive definition would exhaustively cover the subject of justice in holdings.1. A person who acquires a holding in accordance with the principle of justice in acquisition is entitled to that holding.2. A person who acquires a holding in accordance with the principle of justice in transfer, from someone else entitled to the holding, is entitled to the holding.3. No one is entitled to a holding except by applications of i and 2.The complete (...) principle of distributive justice would say simply that a distribution is just if everyone is entitled to the holdings they possess under the distribution.

Tax compliance is a concern to governments around the world. Prior research (Alm, J. and I. Sanchez: 1995, KYKLOS 48, 3–19) has attributed unexplained inter-country differences in compliance rates to differences in social norms. Economics researchers studying tax compliance in the United States (U.S.) (see for example J. Andreoni et al.: 1998, Journal of Economic Literature 36, 818–860) have called for more attention to social (as opposed to economic) influences on tax compliance. In this study, we extend this prior research (...) by explicitly examining the role of social norms [Cialdini, R. and M. Trost: 1998, The Handbook of Social Psychology (Oxford University Press, New York)] on tax compliance in three different countries. We test our research hypotheses using a hypothetical compliance scenario, which was administered in Australia, Singapore, and the U.S. There were differences in compliance rates and social norms among the three countries. Factor analysis of the social norm questions identified three distinct social norm constructs. Two of these factors were significant in explaining tax compliance behavior. The first and most influential factor was taxpayers’ own personal moral beliefs, along with the beliefs of those close to them (e.g., friends and important others). The second significant factor represented societal views of proper behavior. We conclude that social norms help to explain tax compliance intentions and why tax compliance rates are higher than would be predicted by strictly economic models. (shrink)

The concept of individuality as applied to species, an important advance in the philosophy of evolutionary biology, is nevertheless in need of refinement. Four important subparts of this concept must be recognized: spatial boundaries, temporal boundaries, integration, and cohesion. Not all species necessarily meet all of these. Two very different types of pluralism have been advocated with respect to species, only one of which is satisfactory. An often unrecognized distinction between grouping and ranking components of any species concept is necessary. (...) A phylogenetic species concept is advocated that uses a grouping criterion of monophyly in a cladistic sense, and a ranking criterion based on those causal processes that are most important in producing and maintaining lineages in a particular case. Such causal processes can include actual interbreeding, selective constraints, and developmental canalization. The widespread use of the biological species concept is flawed for two reasons: because of a failure to distinguish grouping from ranking criteria and because of an unwarranted emphasis on the importance of interbreeding as a universal causal factor controlling evolutionary diversification. The potential to interbreed is not in itself a process; it is instead a result of a diversity of processes which result in shared selective environments and common developmental programs. These types of processes act in both sexual and asexual organisms, thus the phylogenetic species concept can reflect an underlying unity that the biological species concept can not. (shrink)
