This book provides the reader with a detailed and captivating account of the story where, for the first time, physicists ventured into proposing a new force of nature beyond the four known ones - the electromagnetic, weak and strong forces, and gravitation - based entirely on the reanalysis of existing experimental data. Back in 1986, Ephraim Fischbach, Sam Aronson, Carrick Talmadge and their collaborators proposed a modification of Newton's Law of universal gravitation. Underlying this proposal were three tantalizing pieces (...) of evidence: 1) an energy dependence of the CP (particle-antiparticle and reflection symmetry) parameters, 2) differences between the measurements of G, the universal gravitational constant, in laboratories and in mineshafts, and 3) a reanalysis of the Eötvos experiment, which had previously been used to show that the gravitational mass of an object and its inertia mass were equal to approximately one part in a billion. The reanalysis revealed that, contrary to Galileo's position, the force of gravity was in fact very slightly different for different substances. The resulting Fifth Force hypothesis included this composition dependence and also added a small distance dependence to the inverse-square gravitational force. Over the next four years numerous experiments were performed to test the hypothesis. By 1990 there was overwhelming evidence that the Fifth Force, as initially proposed, did not exist. This book discusses how the Fifth Force hypothesis came to be proposed and how it went on to become a showcase of discovery, pursuit and justification in modern physics, prior to its demise. In this new and significantly expanded edition, the material from the first edition is complemented by two essays, one containing Fischbach's personal reminiscences of the proposal, and a second on the ongoing history and impact of the Fifth Force hypothesis from 1990 to the present. <.

In _No Easy Answers_, Allan Franklin offers an accurate picture of science to both a general reader and to scholars in the humanities and social sciences who may not have any background in physics. Through the examination of nontechnical case studies, he illustrates the various roles that experiment plays in science. He uses examples of unquestioned success, such as the discoveries of the electron and of three types of neutrino, as well as studies that were dead ends, wrong turns, (...) or just plain mistakes, such as the “fifth force,” a proposed modification of Newton's law of gravity. Franklin argues that science is a reasonable enterprise that provides us with knowledge of the natural world based on valid experimental evidence and reasoned and critical discussion, and he makes clear that it behooves all of us to understand how it works.

Experiments often disagree. How then can scientific knowledge be based on experimental evidence? In this paper I will examine four episodes from the history of recent physics: the suggestion of a Fifth Force, a modification of Newton’s law of gravitation; early attempts to detect gravitational radiation ; the claim that a 17-keV neutrino exists; and experiments on atomic-parity violation and on the scattering of polarized electrons and their relation to the Weinberg-Salam unified theory of electroweak interactions. In each of (...) these episodes discordant results were reported, and a consensus was later reached that one result—or set of results—was incorrect. I will examine the process of reaching that consensus. I will show that the decision was reached by reasoned discussion based on epistemological and methodological criteria. It then follows that we may use experimental evidence as the basis of scientific knowledge. (shrink)

The Scientific Revolution was far from the anti-Aristotelian movement traditionally pictured. Its applied mathematics pursued by new means the Aristotelian ideal of science as knowledge by insight into necessary causes. Newton’s derivation of Kepler’s elliptical planetary orbits from the inverse square law of gravity is a central example.

Contrary to the views expressed in many introductory physics textbooks, Henry Cavendish did not measure G, the gravitational constant contained in Newton’s Law of Universal Gravitation, F = G m1m2/r2. As the title of his paper states, Cavendish conducted “Experiments to Determine the Density of the Earth (1798).” As discussed below, one can use that measurement to determine G, but that was not Cavendish’s intent. In fact, the determination of G was not done until the latter part of the (...) nineteenth century. (shrink)

In 1986 Ephraim Fischbach, Sam Aronson, and Carrick Talmadge proposed a modification of Newton’s law of universal gravitation. This modification changed the gravitational potential from V = −Gm1m2∕r to V = [1 + αe−r∕λ] where α, the strength of the interaction, was approximately one percent and the range of the force λ was approximately 100 meters. This additional term was known as the Fifth Force. This suggestion was based on tantalizing evidence provided by a reanalysis of the Eötvös experiment, (...) an early test of the equivalence principle, a difference between the measured value of G, the gravitational constant, as determined by laboratory measurements and those performed in mineshafts, and a small energy dependence in the CP-violating parameters in K0-meson decay. The two initial measurements of the Fifth Force disagreed. One supported its existence and the other did not. How this discrepancy was resolved and the subsequent history of experiments on the Fifth Force will be discussed. By 1990 the consensus was that such a Fifth Force did not exist. Despite that judgment, work continued, and the more recent history of the Fifth Force is also discussed. The consensus remains that there is no Fifth Force. (shrink)

Newton’s Opticks was in no way directed at artists, but the great prestige of its author, as well as its proposal of possible principles of color-harmony, and its establishment of the circle as the most graphic format for illustrating color-relationships, ensured the book a place in the repertory of coloristic art-theory from the eighteenth century until the present day. And, although it was implicit rather than explicit in the Opticks, the idea of complementarity continued to fascinate painters well into (...) the twentieth century. But in painting, the long-standing focus on chiaroscuro as the essential basis of pictorial structure inhibited the acceptance of the notion that colors are inherent in light alone; and Newton’s theory failed to make much headway against the traditional Aristotelianism, which was revived most eloquently by Goethe at the close of the eighteenth century. It was only two centuries later, in the new light-based art of holography, that the Opticks again became a text to conjure with. (shrink)

Recent discussions of emergence in physics have focussed on the use of limiting relations, and often particularly on singular or asymptotic limits. We discuss a putative example of emergence that does not fit into this narrative: the case of phonons. These quasi-particles have some claim to be emergent, not least because the way in which they relate to the underlying crystal is almost precisely analogous to the way in which quantum particles relate to the underlying quantum field theory. But there (...) is no need to take a limit when moving from a crystal lattice based description to the phonon description. Not only does this demonstrate that we can have emergence without limits, but also provides a way of understanding cases that do involve limits. (shrink)

Prevailing ethical thinking about informed consent to clinical research is characterized by theoretical confidence and practical disquiet. On the one hand, bioethicists are confident that informed consent is a fundamental norm. And, for the most part, they are confident that what makes consent to research valid is that it constitutes an autonomous authorization by the research participant. On the other hand, bioethicists are uneasy about the quality of consent in practice. One major source of this disquiet is substantial evidence of (...) the “therapeutic misconception”—the tendency of patient-subjects in clinical trials to confuse participating in research with receiving personalized medical care.

It is shown that stochastic observables defined by an instrument need not, and generally do not, commute.

A predominant ethical view holds that physician‐investigators should conduct their research with therapeutic intent. And since a physician offering a therapy wouldn't prescribe second‐rate treatments, the experimental intervention and the best proven therapy should appear equally effective. "Clinical equipoise" is necessary. But this perspective is flawed. The ethics of research and of therapy are fundamentally different, and clinical equipoise should be abandoned.

This paper argues that many objections against, and limitations of, corporate codes of conduct can be addressed if a meaningful integration can be established between CSR and ethics management practices within corporations. It is proposed that the notion of the triple bottom‐line finally presents corporations with a mechanism to establish this integration. The paper draws on the second South African King Report on Corporate Governance, which succeeded in integrating corporate governance, ethics management and triple bottom‐line reporting by advocating what it (...) called ‘Integrated Sustainability’. The paper argues that this is an example of how ethics management initiatives like code development become more meaningful, if they can be related to the corporation's CSR initiatives and reporting practices. Integration between ethics management and CSR in the context of triple bottom‐line reporting reframes corporate success in a way that makes both ethics management and CSR activities more meaningful. In fact, it is argued that in the absence of a social grammar that establishes this integration, neither codes nor CSR can foster meaningful organizational integrity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Incoherence of Determining Death by Neurological Criteria: A Commentary on Controversies in the Determination of Death, A White Paper by the President’s Council on Bioethics*Franklin G. Miller** (bio) and Robert D. Truog (bio)Traditionally the cessation of breathing and heart beat has marked the passage from life to death. Shortly after death was determined, the body became a cold corpse, suitable for burial or cremation. Two technological changes (...) in the second half of the twentieth century prompted calls for a new, or at least expanded, definition of death: the development of intensive care medicine, especially the use of mechanical ventilators, and the advent of successful transplantation of vital organs. Patients with profound neurological damage, leaving them incapable of breathing on their own and in an irreversible coma, could be maintained for some period of time with the aid of mechanical ventilation. The situation of these patients posed two ethical questions. Is it appropriate to stop life-sustaining treatment? If so, is it acceptable to retrieve vital organs for transplantation to save the lives of others before stopping treatment?In 1968, the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death proposed that death could be determined on the basis of neurological criteria, thus providing a positive answer to these two questions (Ad Hoc Committee 1968). According to the position of this committee, patients diagnosed with the cessation of brain function are dead, despite the fact that they breathe and circulate blood with the aid of mechanical ventilation. [End Page 185] Because they are dead, it is appropriate, indeed imperative, to stop mechanical ventilation. And because they are dead, it becomes ethical to procure vital organs for transplantation before stopping what otherwise would be life-sustaining treatment. Remarkably, this innovative neurological determination of death became, with little debate or controversy, the established position in medical ethics and the law throughout the United States.The Harvard Committee articulated the diagnosis of “irreversible coma,” but merely asserted that this condition constituted death. No explanatory rationale was provided. It fell to the President’s Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research to provide an authoritative rationale in its 1981 report, Defining Death. The second paragraph of the report set the stage as follows: “The question addressed here is not inherently difficult or complicated. Simply, it is whether the law ought to recognize new means for establishing that the death of a human being has occurred” (President’s Commission 1981, p. 3). The Commission claimed that “death is a unitary phenomenon” (p. 7) and that the determination of death by neurological criteria, in terms of the absence of all brain function, is consistent with the traditional conception of death as the cessation of vital functioning of the organism as a whole. The key issue is the integrative functioning of the human organism, which ceases to exist, according to the Commission, when the whole brain, including higher cortical areas and the brain stem, fails to function. Although “brain-dead” patients do not appear to be dead—i.e., the reality of their death is “masked” by the activity of mechanical ventilation—the patient’s body has irreversibly lost all capacity for integrative functioning. In the words of the Commission: “When artificial means of support mask this loss of integration as measured by the old methods [cessation of respiration and heart beat], brain-oriented criteria and tests provide a new window on the same phenomenon” (p. 33). The President’s Commission was instrumental in developing and establishing “The Uniform Definition of Death Act”: “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead” (p. 2).Although the question posed by the President’s Commission was easy to articulate, the answer, over time, has proved complicated and controversial. The coherence and cogency of determining death by neurological criteria has been challenged. Various experts have demonstrated that “brain-dead” patients maintained on mechanical ventilation display a range of vital, integrative, functioning, which conflicts with the judgment that they are dead (Truog and...

That bad things happen to good people was as true in early China as it is today. Franklin Perkins uses this observation as the thread by which to trace the effort by Chinese thinkers of the Warring States Period, a time of great conflict and division, to seek reconciliation between humankind and the world. Perkins provides rich new readings of classical Chinese texts and reflects on their significance for Western philosophical discourse.

In the last three decades, the consideration of whether non-human animals should be ascribed any moral status, and if so in what way it ought to be ascribed to them, has become of central philosophical, political and economic importance. Thus, given thecontemporary significance of what may be called (jar simplicity’s sake) the “animal issue,” it is worthwhile to examine in what way Ancient Greek philosophy might contribute to our understanding of the issue and to our philosophical response to it. With (...) this in mind,in this essay I examine the issue of the moral status of animals from a “critical” Aristotelian perspective, on the basis of which I shall attempt: (§I) to show how, unlike the Cartesian view of animal nature, Aristotle’s conception of the non-moral status of animals stillinforms the prevailing contemporary view of the animal, and (§II) to establish that Aristotle’s failure to ascribe moral status to animals should be rejected (a) given his admission that animals are, by nature, capable of suffering while they are unable to engage in rational deliberation, and (b) given his understanding of the connection between moral blameworthiness, natural disposition, and various kinds of acts, particularly un-chosen and chosen willing acts. In this way, we shall show that although the prevailing contemporary view of the animal’s moral status represents a slightly more “elevated” view than Aristotle’s, insofar as (typically) we do not explicitly claim, as Aristotle did, that animals are due no moral consideration, by critically appropriating the relevant Aristotelian texts, we nonetheless findrich philosophical evidence that permits us to further elevate our conception of the moral status of animals such that we are prepared to grant them genuine moral significance, not just in theory but also in practice.

The use of brain imaging technology as a common tool of research has spawned concern and debate over how investigators should respond to incidental fndings discovered in the course of research. In this article, we argue that investigators have an obligation to respond to incidental fndings in view of their entering into a professional relationship with research participants in which they are granted privileged access to private information with potential relevance to participants' health. We discuss the scope and limits of (...) this professional obligation to respond to incidental fndings, bearing in mind that the relationship between investigators and research participants differs fundamentally from the doctor-patient relationship.

In this paper I offer a new interpretation of the philosophical method of the "Meno." In the opening discussion of the dialogue, Plato introduces a restriction on answers in dialectical inquiry, which I call the Dialectical Requirement (DR). The DR is applied twice in the "Meno," in different ways (75d5-7, 79d1-3). In the first section of the paper, I argue that the two applications of the DR represent the beginning and end of dialectic. This shows that dialectical inquiry starts from (...) our linguistic competence with the name of the property we investigate, and ends only when we have an account saying what is common to and explanatory of the bearers of that property. Dialectic begins in our ordinary ability to speak and think about the world, and ends in genuine grasp of the underlying causes of nature. In the second section, I describe the resources of linguistic competence, and their role in dialectical progress. Our linguistic competence with the name of a property enables us to make a wide variety of statements about the property and its bearers in ordinary discourse. In dialectic, these ordinary statements act as a portfolio in which the property under investigation is presented to us writ large, through its instances, types, species, etc. We seek to develop an account that says what is common to, and explanatory of the phenomena in the portfolio. When an account is inconsistent with one of the things we tend to say, this demands revision either in the account, or in the portfolio of statements. In this way, the process by which we develop our account also helps to organize and revise the statements in our portfolio so that they and the account ultimately form a coherent, explanatory body of statements.

: Bioethicists have failed to understand the pervasively paternalistic character of research ethics. Not only is the overall structure of research review and regulation paternalistic in some sense; even the way informed consent is sought may imply paternalism. Paternalism has limits, however. Getting clear on the paternalism of research ethics may mean some kinds of prohibited research should be reassessed.

Why was Leibniz so fascinated by Chinese philosophy and culture? What specific forms did his interest take? How did his interest compare with the relative indifference of his philosophical contemporaries and near-contemporaries such as Spinoza and Locke? In this highly original book, Franklin Perkins examines Leibniz's voluminous writings on the subject and suggests that his interest was founded in his own philosophy: the nature of his metaphysical and theological views required him to take Chinese thought seriously. Leibniz was unusual (...) in holding enlightened views about the intellectual profitability of cultural exchange, and in a broad-ranging discussion Perkins charts these views, their historical context, and their social and philosophical ramifications. The result is an illuminating philosophical study which also raises wider questions about the perils and rewards of trying to understand and learn from a different culture. (shrink)

Business ethics has largely been written from the perspective of analytical philosophy with very little attention paid to the work of continental philosophers. Yet although very few of these philosophers directly discuss business ethics, it is clear that their ideas have interesting applications in this field.

Topics covered include agency, stakeholder theory, organizational culture, organizational justice, moral decision-making, leadership, whistle-blowing, corporate social responsibility, globalization and sustainability. The book includes a number of features designed to aid comprehension, including a detailed glossary of key terms, text boxes explaining key concepts, and a wide range of examples from the world of business.

“Free Will” is a philosophical term of art for a particular sort of capacity of rational agents to choose a course of action from among various alternatives. Which sort is the free will sort is what all the fuss is about. (And what a fuss it has been: philosophers have debated this question for over two millenia, and just about every major philosopher has had something to say about it.) Most philosophers suppose that the concept of free will is very (...) closely connected to the concept of moral responsibility. Acting with free will, on such views, is just to satisfy the metaphysical requirement on being responsible for one's action. (Clearly, there will also be epistemic conditions on responsibility as well, such as being aware—or failing that, being culpably unaware—of relevant alternatives to one's action and of the alternatives' moral significance.) But the significance of free will is not exhausted by its connection to moral responsibility. Free will also appears to be a condition on desert for one's accomplishments (why sustained effort and creative work are praiseworthy); on the autonomy and dignity of persons; and on the value we accord to love and friendship.
