ABSTRACT The question of axiomatizability of first-order temporal logics is studied w.r.t. different semantics and several restrictions on the language. The validity problem for logics admitting flexible interpretations of the predicate symbols or allowing at least binary predicate symbols is shown to be ?1 1-complete. In contrast, it is decidable for temporal logics with rigid monadic predicate symbols but without function symbols and identity.

There are two competing models for how to understand Aquinas’s hylomorphic theory of material substances: the Simple Model, according to which material substances are composed of prime matter and substantial form, and the Expanded Model, according to which material substances are composed of prime matter, substantial form, and all of their accidental forms. In this paper, I first explain the main differences between these two models and show how they situate Aquinas’s theory of material substances in two different places within (...) the contemporary debate on concrete particulars, highlighting several advantages that Aquinas’s approach has over other varieties of substratum and bundle theory along the way. I then offer some reasons to think that the Expanded Model, as a theory of concrete particulars, is preferable. I argue that the Expanded Model avoids two major concerns for the Simple Model: the problem of extrinsicality, and the problem of too-many-possessors. (shrink)

Although William James formed his philosophical views in direct reaction to the Hegelianism then dominant in American and British institutions, modern critics have tended to reject James’s criticism of G. W. F. Hegel as superficial and outdated. This is in part due to James’s energetic rhetorical style, but also because James at his most polemical tends to present his pluralistic and pragmatist empiricism as diametrically opposed to Hegel’s monistic and intellectualistic idealism, so that it is not clear how the two (...) theories could engage in any meaningful dialogue. This chapter presents a different interpretation of the engagement between James and Hegel. On this interpretation, James’s criticisms of Hegel emerge from what he perceives to be a common starting point: the attempt to find the world to be “a home.” As such, James’s criticisms of Hegel should be understood as offering a kind of internal critique. According to James, Hegel offers too narrow an account of what it is for beings like us to “feel at home” in the world. This is a unique and internal criticism of Hegel which deserves to be taken seriously. (shrink)

It is often argued that certain metaphysical complications surrounding the phenomenon of monozygotic twinning force us to conclude that, prior to the point at which twinning is no longer possible, the zygote or early embryo cannot be considered an individual human organism. In this essay, I argue, on the contrary, that there are in fact several ways of making sense of monozygotic twinning that uphold the humanity of the original zygote, but also that there is no easy answer to what (...) happens when the human zygote twins. All of the options available carry with them one or more surprising, alarming, or otherwise counterintuitive implications. All things considered, I conclude that the “budding option,” according to which the original human organism present before twinning carries on as one of the resulting embryos but not the other, is the most plausible explanation of what happens when a human zygote twins.

Paracelsus was a transmutational alchemist: For most of his career, he believed that one metal could be turned into another. In an alchemical text, the De renovatione et restauratione, he explored the theoretical foundations of transmutation and hinted at recipes for bringing it about. He proposed that from plants, gems, metals, and minerals might be prepared a class of marvelous medicaments, which he called prima entia (first entities). Each primum ens had particular uses, but the entia were all supposed to (...) be able to revitalize the human body and cleanse it of disease. Certain entia could also transmute metals. The De renovatione et restauratione affirmed the metaphysical centrality, in goldmaking and medicine alike, not just of purification or alteration but of renewal and transformation. It expressed the author’s eschatological excitement at God’s works of wonder, whether within or above nature. (shrink)

The Language of Atoms argues that Epicurean writing, specifically Lucretius', offers a theory of performative language, of how language acts rather than describes.

The rhetoric of 'needs' has been used to legitimate all major turns in UK health policy since 1936. This study identifies the ethical, policy and technical issues arising from the concept of needs. In the first part a theory of needs is developed, which takes into account both the philosophical traditions and the practical problems arising in daily health care. In a second part, health systems throughout the world are described and compared, addressing ethical as well as economical questions. Its (...) interdisciplinary approach will make The Need for Healthcare important reading not only for those interested in or employed in the health care sector but also for students of philosophy.

Engineering Ethics: Challenges and Opportunities aims to set a new agenda for the engineering profession by developing a key challenge: can the great technical innovation of engineering be matched by a corresponding innovation in the acceptance and expression of ethical responsibility? Central features of this stimulating text include: · An analysis of engineering as a technical and ethical practice providing great opportunities for promoting the wellbeing and agency of individuals and communities. · Elucidation of the ethical opportunities of engineering in (...) three key areas: Engineering for Peace, emphasising practical amelioration of the root causes of conflict rather than military solutions. Engineering for Health, focusing on close collaboration with healthcare professionals for both the promotion and restoration of health. Engineering for Development, providing effective solutions for the reduction of extreme poverty. · Innovative strategies for implementing these ethical opportunities are described: Emphasis on the personal responsibility of every engineer and on the benefits of supporting social structures. Use of language and concepts that are appealing to business managers and political decision makers. · Future prospects for increasing the acceptance and expression of ethical responsibility by engineers are envisaged. · Engineering Ethics: Challenges and Opportunities provides engineers, decision makers and the wider public with new understanding of the potential of engineering for the promotion of human flourishing.

This is a welcome addition to the scant literature in English on the life of the great seventeenth-century German philosopher and polymath, Gottfried Wilhelm Leibniz. No full-scale biography of Leibniz has appeared in English since John Milton Mackie devised a condensation of G. E. Guhrauer’s still standard work in 1845. Some material from unpublished papers was incorporated into J. T. Merz’s account. Since then virtually nothing has been attempted in this area of Leibniz scholarship, in spite of the fact (...) that much important work has been done, especially in German, culminating in the fine Leben und Werk von. G. W. Leibniz by Kurt Müller and Gisela Krönert. If for no other reason than the dearth of English treatments of the subject, Mr. Aiton’s biography would be a significant contribution. (shrink)

What is 'legal' about bioethics? What are the ideas and artefacts that bioethics encompasses, and how are they related to law? What is the role of law in bioethics? In this work, Calvin Ho attempts to address these questions in the context of the governance of human pluripotent stem cell research. In essence, he argues that the hybridization of law, through processes, devices and techniques of juridification, has helped to constitute bioethics as a public sphere and an emergent civic epistemology. (...) Drawing on his multi-sited ethnographic fieldwork and on Actor-Network-Theory, Ho explains how the law has, through bioethics, contributed to the scientific and public understanding of human pluripotent stem cell research and its artefacts, particularly the embryo and human-animal combinations. Although the focus of his work is on bioethical developments in Singapore over a period of more than 15 years, parallel developments in key jurisdictions (especially the United States of America and the United Kingdom) and in international science policy are also evaluated. It is through appreciating how it has progressed that bioethics will be better able to engage with future challenges presented by advances in human embryo research and gene editing techniques, among others.
