Mathematical realism is the doctrine that mathematical objects really exist, that mathematical statements are either determinately true or determinately false, and that the accepted mathematical axioms are predominantly true. A realist understanding of set theory has it that when the sentences of the language of set theory are understood in their standard meaning, each sentence has a determinate truth value, so that there is a fact of the matter whether the cardinality of the continuum is א2 or whether there are (...) measurable cardinals, whether or not those facts are knowable by us.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

This paper provides a new rationale for equating brain death with the death of the human organism, in light of well-known criticisms made by Alan D Shewmon, Franklin Miller and Robert Truog and a number of other writers. We claim that these criticisms can be answered, but only if we accept that we have slightly redefined the concept of death when equating brain death with death simpliciter. Accordingly, much of the paper defends the legitimacy of redefining death against objections, before (...) turning to the specific task of defending a new rationale for equating brain death with death as slightly redefined.

Tarski and Mautner proposed to characterize the "logical" operations on a given domain as those invariant under arbitrary permutations. These operations are the ones that can be obtained as combinations of the operations on the following list: identity; substitution of variables; negation; finite or infinite disjunction; and existential quantification with respect to a finite or infinite block of variables. Inasmuch as every operation on this list is intuitively "logical", this lends support to the Tarski-Mautner proposal.

Conceived as a solution to clinical dilemmas, and now required by organizations for hospital accreditation, ethics committees have been subject only to small-scale studies. The wide use of ethics committees and the diverse roles they play compel study. In 1999 the University of Pennsylvania Ethics Committee Research Group (ECRG) completed the first national survey of the presence, composition, and activities of U.S. healthcare ethics committees (HECs). Ethics committees are relatively young, on average seven years in operation. Eighty-six percent of ethics (...) committees report that they play a role in ongoing clinical decision making through clinical ethics consultation. All are engaged in developing institutional clinical policy. Although 4.5% of HECs write policy on managed care, 50% of HEC chairs feel inadequately prepared to address managed care. The power and activity of ethics committees parallels the composition of those committees and the relationship of members to their institutions. The role of ethics committees across the nation in making policies about clinical care is greater than was known, and ethics committees will likely continue to play an important role in the debate and resolution of clinical cases and clinical policies.

This is not an overly ambitious paper. What I would like to do is to take a thesis that most people would regard as wildly implausible, and convince you that it is, in fact, false. What's worse, the argument I shall give is by no means airtight, though I hope it's reasonably convincing. The thesis has to do with the fuzzy boundaries of terms that refer to familiar middle-sized objects, terms like ‘Kilimanjaro’ and ‘the tallest mountain in Africa.’ It is (...) intuitively clear that Kilimanjaro has a fuzzy boundary, so that there are some clods of earth at the base of the mountain for which there isn't anything, either in our practices in using the word ‘Kilimanjaro’ or in the facts of geography, that determines an answer to the question whether the clod is a part of Kilimanjaro.

That reference is inscrutable is demonstrated, it is argued, not only by W. V. Quine's arguments but by Peter Unger's "Problem of the Many." Applied to our own language, this is a paradoxical result, since nothing could be more obvious to speakers of English than that, when they use the word "rabbit," they are talking about rabbits. The solution to this paradox is to take a disquotational view of reference for one's own language, so that "When I use 'rabbit,' I (...) refer to rabbits" is made true by the meaning of the word "refer." The reference relation is extended to other languages by translation. The explanation for this peculiarly egocentric conception of semantics-questions of others' meanings are settled by asking what I mean by words of my language-is to be found in our practice of predicting and explaining other people's behavior by empathetic identification. I understand other people's behavior by asking what I would do in their place. (shrink)

In 1992, the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) passed a mandate that all its approved hospitals put in place a means for addressing ethical concerns.Although the particular process the hospital uses to address such concernsmay vary, the hospital or healthcare ethics committee (HEC) is used most often. In a companion study to that reported here, we found that in 1998 over 90% of U.S. hospitals had ethics committees, compared to just 1% in 1983, and that many (...) have some and a few have sweeping clinical powers in hospitals.

Clinical bioethics is big business. There are now hundreds of people who bioethics in community and university hospitals, nursing homes, rehabilitation and home care settings, and some who play the role of clinical ethics consultant to transplant teams, managed care companies, and genetic testing firms. Still, there is as much speculation about what clinically active bioethicists actually do as there was ten years ago. Various commentators have pondered the need for training standards, credentials, exams, and malpractice insurance for ethicists engaged (...) in clinical consultation. Much of the discussion seems to accept an implicit presumption that all clinical ethics consultation practices look pretty much alike. But is this accurate? What do clinical ethicists do, how and where do they do it, and what kind of clinical ethics is useful in the hospital and in other settings? (shrink)

In a first major study, the UK’s Royal Society found that 76% of people in the UK are in favour of therapeutic germline genomic editing to correct genetic diseases in human embryos, but found there was little appetite for germline genomic editing for non‐therapeutic purposes. Assuming the UK and other governments acted on these findings, can lawmakers and policymakers coherently regulate the use of biomedical innovations by permitting their use for therapeutic purposes but prohibiting their use for enhancement purposes? This (...) paper examines the very common claim in the enhancement literature that the therapy v enhancement distinction does little meaningful work in helping us think through the ethical issues, a claim that has significant implications for these lawmakers and policymakers who may wish to regulate genomic editing techniques to reflect the findings of this important study. The focus of this paper is on germline genomic editing as one of the main themes in this special issue. (shrink)

In 1944, Martin Crowe, a Catholic priest, wrote a doctoral dissertation titled The Moral Obligation of Paying Just Taxes. His dissertation summarized and analyzed 500 years of theological and philosophical debate on this topic, much of which took place in Latin. Since Crowe’s dissertation, not much has been written on the topic of tax evasion from an ethical perspective, with a few exceptions. In 1998 and 1999, a few articles were published on the ethics of tax evasion in the Journal (...) of Accounting, Ethics & Public Policy. An edited book on this topic was published in 1998. The present paper summarizes, updates and expands on Crowe’s work and the other more recent work that has been published on this topic. Three basic views on the ethics of tax evasion have emerged over the centuries. This article presents and critiques those three views and raises some questions about points that have not yet been explored in the literature. (shrink)

Insider trading has received a bad name in recent decades. The popular press makes it sound like an evil practice where those who engage in it are totally devoid of ethical principles. Yet not all insider trading is unethical and some studies have concluded that certain kinds of insider trading are actually beneficial to the greater investment community. Some scholars in philosophy, law and economics have disputed whether insider trading should be punished at all while others assert that it should (...) be illegal in all cases. This paper explores the nature of insider trading and analyzes the issues to determine the positive and negative aspects of insider trading, and how policy should be changed. The best hope would be for studies to be made that isolate the individuals or groups who are fraudulently harmed by insider trading. If any such groups exist, then clearly worded legislation could be passed to prevent any fraud from being committed against these individuals and groups, while allowing non-fraudulent transactions to be completed without fear of prosecution. Until it can be clearly determined that someone is fraudulently harmed by insider trading, there should be no law or regulation restricting the practice, since such restrictions violate individual rights and will likely have a negative market reaction.

Deflationists about truth embrace the positive thesis that the notion of truth is useful as a logical device, for such purposes as blanket endorsement, and the negative thesis that the notion doesn’t have any legitimate applications beyond its logical uses, so it cannot play a significant theoretical role in scientific inquiry or causal explanation. Focusing on Christopher Hill as exemplary deflationist, the present paper takes issue with the negative thesis, arguing that, without making use of the notion of truth conditions, (...) we have little hope for a scientific understanding of human speech, thought, and action. For the reference relation, the situation is different. Inscrutability arguments give reason to think that a more-than-deflationary theory of reference is unattainable. With respect to reference, deflationism is the only game in town. (shrink)

This paper examines the recent prominent view in medical ethics that withdrawing life-sustaining treatment is an act of killing. I trace this view to the rejection of the traditional claim that withdrawing LST is an omission rather than an act. Although that traditional claim is not as problematic as this recent prominent view suggests, my main claim is that even if we accepted that withdrawing LST should be classified as an act rather than as an omission, it could still be (...) classified as letting die rather than killing. Even though omissions are contrasted with acts, letting die need not be, for one can let die by means of acts. The remainder of the paper is devoted to establishing this claim and addresses certain objections to it. (shrink)

The common view is that insider trading is always unethical and illegal. But such is not the case. Some forms of insider trading are legal. Furthermore, applying ethical principles to insider trading causes one to conclude that it is also sometimes ethical. This paper attempts to get past the hype, the press reports, and the political grandstanding to get to the truth of the matter. The author applies two sets of ethical principles – utilitarianism and rights theory – in an (...) attempt to determine when, and in what circumstances, insider trading is ethical. The views of Henry Manne, an early proponent of insider trading, are critically examined, as are the major arguments against insider trading. Is insider trading good for the company if it is used as a form of executive compensation which makes it possible to pay lower salaries than would otherwise be the case? Does insider trading cause the stock market to work more efficiently? If insider trading does increase efficiency, is that sufficient to call for its total legalization, or are there other things to be considered? Several arguments against insider trading have been put forth over the last few decades but there are problems with all of them. One of the main arguments is the fairness argument. The problem with this argument is that different people have different definitions of unfairness. A closely related argument is the level playing field argument, which advocates wider dissemination of information so that it is less asymmetric. One problem with the level playing field argument is that it is better applied to sporting competitions than to trading in information. Some economists argue that forcing the disclosure of nonpublic information can actually result in more harm than good and must necessarily involve the violation of property rights. Other arguments examined in this chapter include the fiduciary duty argument, the problem of outside traders, the misappropriation doctrine and the restrictions that insider trading laws place on freedom of speech and press. The article concludes by setting forth some principles or guidelines to determine when insider trading should be punished and when it should not. (shrink)

Over the past few decades, a body of research has developed examining the academic dishonesty of university and college students. While research has explored academic dishonesty amongst American criminal justice and policing students, no research has specifically focused on investigating the dynamics and correlates of academic dishonesty amongst Australian criminology students. This study drew upon data obtained from a survey of 79 undergraduate criminal justice and policing students studying at an Australian university. Overall, the results suggest that male gender, viewing (...) academic dishonesty as less serious and holding justifications for engaging in this type of behaviour were significant predictors of self-reported academic dishonesty. The findings suggest that more proactive strategies need to be implemented by universities to prevent student involvement in academic dishonesty. (shrink)

We have long used mechanical devices to compensate for physical disability. Soon, however, it may be possible to augment mental capacity—to add memory or upgrade processing power. We should ponder the enormous moral implications of the machine‐assisted mind now, before it is accomplished.

The Perfect Baby is the most popular introduction to ethical issues in genetics. This new edition has been updated to discuss and debate advances in high tech reproduction, genetic testing, gene therapy, human cloning, and stem cell research. It includes a new epilogue by cloning pioneer Ian Wilmut and Glenn McGee.

In this paper, I examine Jeff McMahan’s arguments for his claim that we are not human organisms, and the arguments of Derek Parfit to the same effect in a recent paper. McMahan uses these arguments to derive conclusions concerning the moral status of embryos and permanent vegetative state patients. My claim will be that neither thinker has successfully shown that we are not human beings, and therefore these arguments do not establish the ethical conclusions that McMahan has sought to draw (...) from the arguments in respect of the moral status of embryos and PVS patients.

George Boolos (1984, 1985) has extensively investigated plural quantifi- cation, as found in such locutions as the Geach-Kaplan sentence There are critics who admire only one another, and he found that their logic cannot be adequately formalized within the first-order predicate calculus. If we try to formalize the sentence by a paraphrase using individual variables that range over critics, or over sets or collections or fusions of critics, we misrepresent its logical structure. To represent plural quantification adequately requires the logical (...) resources of the full second-order predicate calculus. (shrink)
