This paper argues against Logical Realism, in particular against the view that there are facts of matters of logic that obtain independently of us, our linguistic conventions and inferential practices. The paper challenges logical realists to provide a non-intuition based epistemology, one which would be compatible with the empiricist and naturalist convictions motivating much recent anti-realist philosophy of mathematics.

The phrase “minimal risk,” as defined in the United States’ federal research regulations, is ambiguous and poorly defined. This article argues that most of the ambiguity that one finds in the phrase stems from the “daily life risks” standard in the definition of minimal risk. In this article, the author argues that the daily life risks standard should be dropped and that “minimal risk” should be defined as simply “the probability and magnitude of the harm or discomfort anticipated in research (...) are not greater than those encountered during the performance of routine physical or psychological examinations or tests”.

Michael Dummett argued that Frege was a realist while Hans Sluga countered that he was an objective idealist in the rationalist tradition of Kant and Lotze. Sluga ties Frege's idealism to the context principle which he argues Frege never gave up. It is argued that Sluga has correctly interpreted the pre?1891 Frege while Dummett is correct concerning the later period. It is also claimed that the context principle was dropped prior to 1891 to be replaced by the doctrine of unsaturated (...) entities. (shrink)

In Science without numbers Hartry Field attempted to formulate a nominalist version of Newtonian physics?one free of ontic commitment to numbers, functions or sets?sufficiently strong to have the standard platonist version as a conservative extension. However, when uses for abstract entities kept popping up like hydra heads, Field enriched his logic to avoid them. This paper reviews some of Field's attempts to deflate his ontology by inflating his logic.

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.

This essay reviews six different approaches to intellectual property. It and argues that none of these accounts provide an adequate justification of intellectual property laws and policies because (1) there are many different types of intellectual property, and (2) a variety of incommensurable values play a role in the justification of intellectual property. The best approach to intellectual property is to assess and balance competing moral values in light of the particular facts and circumstances.

By a logical theory I mean a formal system together with its semantics, meta-theory, and rules for translating ordinary language into its notation. Logical theories can be used descriptively (for example, to represent particular arguments or to depict the logical form of certain sentences). Here the logician uses the usual methods of empirical science to assess the correctness of his descriptions. However, the most important applications of logical theories are normative, and here, I argue, the epistemology is that of wide (...) reflective equilibrium. The result is that logic not only assesses our inferential practice but also changes it. I tie my discussion to Thagard's views concerning the relationship between psychology and logic, arguing against him that psychology has and should have only a peripheral role in normative (and most descriptive) applications of logic.

Most of the discussion in bioethics and health policy concerning social responsibility for health has focused on society’s obligation to provide access to healthcare. While ensuring access to healthcare is an important social responsibility, societies can promote health in many other ways, such as through sanitation, pollution control, food and drug safety, health education, disease surveillance, urban planning and occupational health. Greater attention should be paid to strategies for health promotion other than access to healthcare, such as environmental and public (...) health and health research.Lifestyle plays a major role in most of the illnesses in industrialised nations.1 Six of the 10 leading factors contributing to the global burden of disease are lifestyle related: unsafe sex, high blood pressure, tobacco use, alcohol use, high cholesterol and obesity.2 Lifestyle-related illnesses also contribute to the rising costs of healthcare. Spending on healthcare accounts for about 16% of the gross domestic product in the USA, or US$1.9 trillion.3 Although smoking has declined steadily there since the 1960s, smoking-related medical expenses are still about US$75.5 billion per year.4 Obesity, which has been climbing in the past two decades, accounts for about US$75 billion in healthcare costs there each year.5 Alcoholism and drug addiction in the USA account for annual healthcare costs of about US$22.5 billion and US$12 billion, respectively.6,7 Federal government spending on healthcare relating to HIV/AIDS is over US$13 billion per year.8Given the well-documented relationship between lifestyle, disease burden and healthcare costs, it makes economic and medical sense to hold individuals morally responsible for their health-related choices. While this view has a great deal of intuitive appeal, it also faces numerous objections.9–12 First, holding individuals entirely responsible for their own health conflicts with medicine’s obligation to treat the sick and society’s obligation ….

This paper is concerned with the genesis of mathematical knowledge. While some philosophers might argue that mathematics has no real subject matter and thus is not a body of knowledge, I will not try to dissuade them directly. I shall not attempt such a refutation because it seems clear to me that mathematicians do know such things as the Mean Value Theorem, The Fundamental Theorem of Arithmetic, Godel's Theorems, etc. Moreover, this is much more evident to me than any philosophical (...) view of mathematics I know of — including my own. So I am going to take mathematics as my starting point. (shrink)

We have seen that despite Feferman's results Gödel's second theorem vitiates the use of Hilbert-type epistemological programs and consistency proofs as a response to mathematical skepticism. Thus consistency proofs fail to have the philosophical significance often attributed to them.This does not mean that consistency proofs are of no interest to philosophers. We know that a ‘non-pathological’ consistency proof for a system S will use methods which are not available in S. When S is as strong a system as we are (...) willing to entertain seriously then a consistency proof for it will yield no epistemological gain. But in other cases philosophers might argue that the proof uses methods which are merely different rather than stronger than those available in the system in question. This claim has been made, for example, in the case of the constructive consistency proofs for elementary number theory. Similar philosophical investigations can be made on relative consistency proofs, since these differ from each other in the principles they employ. For example, most relative consistency proofs can be carried out within elementary number theory, but without using the theory of real numbers, no one has been able to prove the consistency of Quine's ML relative to that of his NF.What about the consistency of all mathematics or of some strong system for set theory? How do we answer the skeptic? Since here a convincing proof is not possible, we have established that the skeptic demands too much. We cannot be certain that our axioms are free from contradiction and must treat them as hypotheses which may be abandoned or modified in the face of further mathematical experience. This attitude is taken by many foundational workers who also go on to voice opinions about thelikelihood that various systems are consistent. Since these opinions are variously supported by appeals to the clarity of the mathematical concept formalized, the existence or non-existence of ‘weird’ models for the system and actual empirical experience with the system, this is surely a fruitful area for philosophical research.

This essay develops a framework for thinking about the moral basis for the commodification of human reproductive materials. It argues that selling and buying gametes and genes is morally acceptable although there should not be a market for zygotes, embryos, or genomes. Also a market in gametes and genes should be regulated in order to address concerns about the adverse social consequences of commodification.

Inappropriate authorship is a common problem in biomedical research and may be becoming one in bioethics, due to the increase in multiple authorship. This paper investigates the authorship policies of bioethics journals to determine whether they provide adequate guidance for researchers who submit articles for publication, which can help deter inappropriate authorship. It was found that 63.3% of bioethics journals provide no guidance on authorship; 36.7% provide guidance on which contributions merit authorship, 23.3% provide guidance on which contributions do not (...) merit authorship, 23.3% require authors to take responsibility for their contributions or for the article as a whole, 20% provide guidance on which contributions merit an acknowledgement but not authorship, 6.7% require authors to describe their contributions, and only 3.3% distinguish between authorship in empirical and conceptual research. To provide authors with effective guidance and promote integrity in bioethics research, bioethics journals should adopt authorship policies that address several important topics, such as the qualifications for authorship, describing authorship contributions, taking responsibility for the research and the difference between authorship in empirical and conceptual research.

The propagation of errors in physics research is studied, with particular attention being paid to the effectiveness of the erratum in avoiding error propagation. We study the citation history of 17 physics papers which have significant errata associated with them. It would appear that the existence of an erratum does not significantly decrease the frequency with which a paper is cited and in most cases the erratum isnot cited along with the original paper. The authors comment on implications for the (...) responsibilities of authors. (shrink)

Informed consent is one of the foundational ethical and legal requirements of research with human subjects. The Nuremberg Code, the Helsinki Declaration, the Belmont Report, the Common Rule and many other laws and codes require that research subjects make a voluntary, informed choice to participate in research.12345 Informed consent is based on the moral principle of respect for autonomy, which holds that rational individuals have a right to make decisions and take actions that reflect their values and preferences. 6 Whereas (...) most guidelines and codes also require that informed consent be properly documented, informed consent is much more than signing a piece of paper: It is a continuous process of communication between the investigator and the research subject. 7 Because the body of knowledge impacting a study frequently changes, subjects should receive information from investigators after they have enrolled in a study, such as significant new findings that may affect their decision to participate in research or clinically useful tests results. 8910 In large studies, some investigators use newsletters to update subjects on the progress of research and other developments.11Most of the ongoing communications between investigators and subjects involve little more than information sharing, without revisiting the decision to participate in research or signing any additional documents. Sometimes, however, it may be necessary for subjects to reaffirm their decision to participate, to re-consent, or to sign or re-sign a document. 8 Re-consent can be defined as an action in which a subject makes the decision to participate in research once again. Re-consent is different from reaffirming a commitment to participate in a study, because in re-consent one actually reconsiders the information necessary to make decision, whereas in reaffirmation one simply expresses ….

This paper is a nontechnical exposition of the author's view that mathematics is a science of patterns and that mathematical objects are positions in patterns. the new elements in this paper are epistemological, i.e., first steps towards a postulational theory of the genesis of our knowledge of patterns.

Mathematical explanation is a topic of great contemporary interest in the philosophy of mathematics. The question of whether mathematics can play an explanatory role in empirical science is thought by many to be the key to making progress on the realism versus anti-realism debate in the philosophy of mathematics. Questions about explanation within mathematics are also interesting and are important for the development of a general account of explanation. In a series of groundbreaking papers from 1978 to 1983, Mark Steiner (...) set the agenda for much of the modern debate about mathematical explanation. In the present paper we look at Steiner’s role in advancing mathematical explanation as a central topic in the philosophy of mathematics and his legacy for the modern debates about mathematical explanation.

We argue that Horgan's program for nominalizing science fails, because its translation of quantitative statements destroys the inferential structures of explanations, predictions and retrodictions of nonquantitative scientific facts.

Nothing has been more central to philosophy of mathematics than the distinction between mathematical and physical objects. Yet consideration of quantum particles shows the inadequacy of the popular spacetime and causal characterizations of the distinction. It also raises problems for an assumption used recently by Field, Hellman and Horgan, namely, that the mathematical realm is metaphysically independent of the physical one.
