The majority of antimicrobials that are produced are administered to animals, particularly food animals. While the overall impact of antimicrobial use in animals on antimicrobial resistance in humans and the environment is unclear, it undeniably has a role. Yet, some degree of antimicrobial use in animals is necessary for animal health and welfare purposes. Balancing the benefits and risks of antimicrobial use in animals is challenging because of the complexity of the problem and limitations in available data. However, a range (...) of measures can be implemented to reduce, refine and optimize antimicrobial use in animals, with a goal of minimizing the impact on human and environmental health while maintaining necessary therapeutic use in animals. A pandemic instrument can provide the necessary foundation for the whole-of-society and whole-of government One Health approach that is required to strengthen surveillance, communication, collaboration, and action.

We present a Kripke model for Girard's Linear Logic (without exponentials) in a conservative fashion where the logical functors beyond the basic lattice operations may be added one by one without recourse to such things as negation. You can either have some logical functors or not as you choose. Commutatively and associatively are isolated in such a way that the base Kripke model is a model for noncommutative, nonassociative Linear Logic. We also extend the logic by adding a coimplication operator, (...) similar to Curry's subtraction operator, which is resituated with Linear Logic's contensor product. And we can add contraction to get nondistributive Relevance Logic. The model rests heavily on Urquhart's representation of nondistributive lattices and also on Dunn's Gaggle Theory. Indeed, the paper may be viewed as an investigation into nondistributive Gaggle Theory restricted to binary operations. The valuations on the Kripke model are three valued: true, false, and indifferent. The lattice representation theorem of Urquhart has the nice feature of yielding Priestley's representation theorem for distributive lattices if the original lattice happens to be distributive. Hence the representation is consistent with Stone's representation of distributive and Boolean lattices, and our semantics is consistent with the Lemmon-Scott representation of modal algebras and the Routley-Meyer semantics for Relevance Logic.

This paper presents the algebraic and Kripke modelsoundness and completeness ofa logic over Boolean monoids. An additional axiom added to thelogic will cause the resulting monoid models to be representable as monoidsof relations. A star operator, interpreted as reflexive, transitiveclosure, is conservatively added to the logic. The star operator isa relative modal operator, i.e., one that is defined in terms ofanother modal operator. A further example, relative possibility,of this type of operator is given. A separate axiom,antilogism, added to the logic (...) causes the Kripke models to support acollection of abstract topological uniformities which become concretewhen the Kripke models are dual to monoids of relations. The machineryfor the star operator is shownto be a recasting of Scott-Montague neighborhood models. An interpretationof the Kripke frames and properties thereof is presented in terms ofcertain CMOS transister networks and some circuit transformation equivalences.The worlds of the Kripke frame are wires and the Kripke relation is a specializedCMOS pass transistor network.

After a discussion of the different treatments in the literature of vacuous descriptions, the notion of descriptor is slightly generalized to function descriptor Ⅎ $\overset \rightarrow \to{y}(x)$ , so as to form partial functions φ = Ⅎ $y(\overset \rightarrow \to{x}).A(\overset \rightarrow \to{x},y)$ which satisfy $\forall \overset \rightarrow \to{x}z(z=\phi \overset \rightarrow \to{x}\leftrightarrow \forall y(A(\overset \rightarrow \to{x},y)\leftrightarrow y=z))$ . We use (intuitionistic, classical or intermediate) logic with existence predicate, as introduced by D. S. Scott, to handle partial functions, and prove that (...) adding function descriptors to a theory based on such a logic is conservative. For theories with quantification over functions, the situation is different: there the addition of Ⅎ yields new theorems in the Ⅎ-free fragment, but an axiomatisation is easily given. The proofs are syntactical. (shrink)

“The Role of the Individual in Evolution” is a prescient yet neglected 1941 work by the 20th century’s most important paleontologist, George Gaylord Simpson. In a curious intermingling of explanation and critique, Simpson engages questions that would become increasingly fundamental in modern biological theory and philosophy. Did individuality, adaptation, and evolutionary causation reside at more than one level: the cell, the organism, the genetically coherent reproductive group, the social group, or some combination thereof? What was an individual, anyway? In this (...) introduction, we highlight two points in a wider historical context. First, recognizing the political context of Simpson’s writing profoundly deepens our understanding of the development of his science as the Modern Evolutionary Synthesis infused biology. Second, this story illuminates the emergence of debates around what would eventually come to be called multilevel selection theory. The organism-centered concept of biological individuality defended by Simpson is situated in relation to the then-emerging Synthesis, in which he was a renowned player, and also in relation to the views he opposed: the “metaphysical” ideas of paleontologists such as Henry Fairfield Osborn, who claimed that some evolutionary trends derived from potentialities already implanted in the germplasm; and the organicist ideas of Ralph W. Gerard and the Chicago School of ecologists, which he derided as all too congenial to totalitarianism. We find parallels between the ways that Simpson thought then about human individuality under totalitarianism and the way he thought about individuality in evolution; not that any causal relationship linked the two, but that commonalities of hierarchical structure exist between single entities and groups in both instances. We then trace the subsequent development of Simpson’s political and philosophical takes on the role of the individual in evolution through the 1960s and lightly sketch out the later fate of the organicist ideas of the Chicago School. Simpson’s paper, originally published in the Journal of the Washington Academy of Sciences, is available as supplementary material in the online version of this article, as part of the "Classics in Biological Theory" collection.

Phonological Knowledge addresses central questions in the foundations of phonology and locates them within their larger linguistic and philosophical context. Phonology is a discipline grounded in observable facts, but like any discipline it rests on conceptual assumptions. This book investigates the nature, status, and acquisition of phonological knowledge: it enquires into the conceptual and empirical foundations of phonology, and considers the relation of phonology to the theory of language and other capacities of mind. The authors address a wide range of (...) interrelated questions, the most central of which is this: is phonological knowledge different from linguistic knowledge in general? They offer responses to this question from a variety of perspectives, each of which has consequences for how phonology and language are conceived. Each also involves a host of further questions concerning the modularity of mind and of language; whether phonology should be included in the language faculty; the nature-convention debate; the content of phonological elements and its relation to phonetic substance; the implications of sign languages for phonology; whether functional and variationist considerations are relevant in phonology; how phonological knowledge arises; and, not least, the data and methods appropriate for phonological inquiry. Phonological Knowledge is an important contribution to the most fundamental issues in phonology and the understanding of language. It will interest researchers in and advanced students of phonology, linguistic theory, and philosophy of language.In addition to the editors, the authors are Mary Beckman, Silvain Bromberger, Jennifer Fitzpatrick, Paul Foulkes, Mark Hale, Morris Hallé, John Harris, Harry van der Hulst, Robert Ladd, G. Lindsey, Scott Myers, Janet Pierrehumbert, Charles Reiss, Shelley Velleman, Marilyn Vihman, and Linda Wheeldon.By relating foundational questions of phonology to their larger linguistic, cognitive, and philosophical contexts this book will generate interest not only among phonologists and their advanced students, but also among all those concerned to understand the forms and functions of language.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peacebuilding: Catholic Theology, Ethics, and Praxis ed. by Robert J. Schreiter, R. Scott Appleby, Gerard F. PowersJames W. McCarty IIIPeacebuilding: Catholic Theology, Ethics, and Praxis Edited by Robert J. Schreiter, R. Scott Appleby, and Gerard F. Powers Maryknoll, NY: Orbis Books, 2010. 480pp. $27.00Peacebuilding results from a four-year research project sponsored by the Catholic Peacebuilding Network. A wide-ranging and interdisciplinary set of fifteen essays, (...) Peacebuilding not only brings to the fore the unique ways that Roman Catholic theology and practice has contributed to the global work of peacebuilding, but it also makes the case that the Catholic Church needs to develop a more robust theology of peacebuilding to complement and strengthen traditional Catholic approaches to the ethics of war and peace. The two most bold proposals along these lines are Daniel Philpott’s call for a papal encyclical on peacebuilding (92, 120) and Maryann Cusimano Love’s proposal of “just peace” criteria for guiding peacebuilding work in a fashion similar to the way “just war” criteria have guided the conduct of war (82, 425–27).Peacebuilding is organized into two main sections. The first documents and theorizes the work of Catholic actors and organizations in peacebuilding work. In one of the most helpful essays in this section, John Paul Lederach describes how the “ubiquitous presence” of the Catholic Church in a society is, in fact, one of the most unique contributions the Church has to make to global peacebuilding. Lederach uses the phrase “ubiquitous presence” to describe the unique role Catholic “actors” play within the “pyramid approach” to peacebuilding that he develops elsewhere (see Lederach, The Moral Imagination: The Art and Soul of Peacebuilding [New York: Oxford University Press, 2005], 79). Because of its hierarchical structure, the Catholic Church—especially in Catholic-majority countries—has the potential to cultivate peacebuilding allies among different sectors of a society: the elite, “midlevel” actors, and at the grassroots level. Many other peacebuilding actors—politicians, civil society activists, and the historic peace churches, for instance—do not have such a ubiquitous presence. While Lederach has previously emphasized the importance of midlevel actors in peacebuilding, in this essay he argues that the “ubiquitous presence” of the Catholic Church [End Page 213] in a society provides a basis for making connections for peacebuilding work among a range of sectors within a society. Several of the other contributors to this book draw on this observation and demonstrate its usefulness to a variety of settings. In my estimation, this is the most important contribution of the volume.The second section consists of six essays that both expand upon existing Catholic moral theology and make the case that Catholic theology needs to develop a more robust theology of peacebuilding. Here we find a range of arguments—from Robert Schreiter’s proposal for a practical theology of reconciliation and Peter Phan’s outline of a fourfold Catholic understanding of interreligious dialogue to Kenneth Himes’s discussion of the ways peacebuilding theory challenges and complements contemporary Catholic social teaching. Himes, in particular, claims that the current acceptance of a Catholic “presumption against war” requires a more robust Catholic approach to conflict transformation; in making his case, he draws on resonances between contemporary peacebuilding theory and recent reflections on jus post bellum (justice after war) as a new category of just war thinking.As in nearly every edited collection, the quality of the essays in Peacebuilding varies. I found the essays in the first section to be the most stimulating. Not only do they highlight the peacebuilding work the Catholic Church is currently doing around the world, they also ground their proposals for how we should understand and do peacebuilding from a Catholic perspective in relevant historical examples.Indeed, the varied nature of the essays in Peacebuilding is precisely what makes it a valuable resource for both researchers and teachers of peacebuilding. On the one hand, it includes essays that break new ground and move forward our understanding of the unique nature of Catholic peacebuilding. On the other, it includes essays that introduce the topic of peacebuilding to students of religion and ethics. This book, then, serves as an excellent resource for a range... (shrink)

From obnoxious public figures to online trolling and accusations of “fake news”, almost no one seems able to disagree without hostility. But polite discord sounds farfetched when issues are so personal and fundamental that those on opposing sides appear to have no common ground. How do you debate the “enemy”? Philosophers Scott Aikin and Robert Talisse show that disagreeing civilly, even with your sworn enemies, is a crucial part of democracy. Rejecting the popular view that civility requires a polite (...) and concessive attitude, they argue that our biggest challenge is not remaining calm in the face of an opponent, but rather ensuring that our political arguments actually address those on the opposing side. Too often politicians and pundits merely simulate political debate, offering carefully structured caricatures of their opponents. These simulations mimic political argument in a way designed to convince citizens that those with whom they disagree are not worth talking to. Good democracy thrives off conflict, but until we learn the difference between real and simulated arguments we will be doomed to speak at cross-purposes. Aikin and Talisse provide a crash course in political rhetoric for the concerned citizen, showing readers why understanding the structure of arguments is just as vital for a healthy democracy as debate over facts and values. But there’s a sting in the tail - no sooner have we learned rhetorical techniques for better disagreement than these techniques themselves become weapons with which to ignore our enemies, as accusations like “false equivalence” and “ad hominem” are used to silence criticism. Civility requires us to be eternally vigilant to the ways we disagree. (shrink)

The most influential account of authority – Joseph Raz's service conception – is an account of the role of authority, in that it is an account of its point or function. However, authority does not have a characteristic role to play, and even if it did, the ability to play a role is not, by itself, sufficient to establish authority. The aim of this essay is to shift our focus from roles that authority plays to roles that people play – (...) which we can also call roles of authority – such as chef, teacher, and parent. To justify authority, we need to justify the practices in which roles of authority play a part. (shrink)

This essay explores how it might be possible to recover a more pluralistic and therefore participatory understanding and exercise of the teaching office in the Christian Church by, first, briefly reflecting upon the historical backdrop to the emergence and development of the role of authoritative ecclesial teacher. Second, I identify some of the ecclesial fault lines and tensions that emerged in the modern and contemporary periods pertaining to teaching authority. Third, I raise the issue of the impact of such developments (...) upon the manner in which Christian churches have sought to offer teachings on ethical issues in recent times. Fourth, I explore, via an ecclesiological analysis that is both a comparative and ecumenical in nature, three visions for retrieving a more participatory and life-giving understanding of the teaching office and practice of the teaching function for our times. The visions explored come from a Reformed, Roman Catholic, and ecumenical standpoint: respectively, those of Richard Robert Osmer, Richard R. Gaillardetz, and Willem Visser 't Hooft. The final section offers some brief conclusions about the potential for truly ecumenical collaboration in moral discernment in the light of such considerations. (shrink)

Law, like language, is the product of social evolution, embodied in custom. The conditions for the emergence of law—embodiment, scarcity, rationality, relatedness and plurality—are outlined, and the context for the emergence of law—dispute resolution—is analysed. Adjudication procedures, rules and enforcementmechanisms, the elements of law, emerge from this context. The characteristics of such a customarily evolved law are its severely limited scope, its negativity, andits horizontality. It is suggested that a legal system (or legal systems) based on the principles of archaic (...) law could answer the needs of social order without permitting the paternalistic interferences with liberty characteristic of contemporary legal systems.

The Church is a sexed body, in both carnal and symbolic terms. The Church has sex, but being the Church it does so in a radically creative way. This article explores the contrast between sex as imagined by the Church and as imagined by evolutionary psychology (Darwinism). It argues that the latter reduces sex to reproduction (repetition) and makes this a metaphysical principle, whereas the Church transforms sex into a means for final beatitude. (Christian sex is not about self-perpetuation, but (...) about welcoming strangers; not about children as possessions, but as God's most precious gifts.) Darwinism strangely repeats a debased (neoscholastic) form of the natural law, whereas the Church looks to follow a law that is the dispossessive desire of God for God. Sex after this law orders us towards the infinite joy of our consummation with and in God, in the fellowship of Christ and the holy saints. (shrink)

(1) What may be gained by applying concepts generalised from economics to methodological problems? The perspective of cost-benefit analysis ('CBA' for short) may help the researcher to see what sorts of questions he should take into account when dealing with particular methodological problems. This claim is supported by applying generalised CBA-thinking to two standard problems of methodology. (2) In the practice of research the handling of basic statements does not normally constitute any problem, and no conscious decision is involved. In (...) the methodological reconstruction the key questions are: 'How can a particular basic statement be criticised?' and 'What are the costs of defending a statement that is "problematic"?' The problem of the empirical 'base' is an investment problem: whether or not to invest time and effort into processing a particular basic statement into a falsifying hypothesis for the theory we wish to test. The valuation of the costs of rejecting or, as the case may be, of defending a basic statement, are objective. (3) With respect to theories, in basic science, the issue is not one of acceptance or rejection of a single theory, but rather of theory preference. Both the rational response to a falsification and rational theory preference are governed by CBA-considerations. The option for one of two competing theories is based upon a CBA where the valuation of benefits and costs is objective. Theory change is an objective process, at least in those fields, where theorising is closely controlled by empirical testing: the better theory drives out the less good theory. The costs of defending a theory that is less good than its competitor are mainly epistemic resources forgone. The use of CBA in methodology not only is compatible with Popper's position, but it may pay to view Popper's methodology as an application of CBA to epistemic situations. (shrink)

SummaryIn this paper Russell's discovery of external relations and his refutation of the doctrine of internal relations is traced to Hume's view on “philosophical” relations. Next the concepts of internal and external relation are applied to the analysis of knowledge. The most widely received analysis, the Justified True Belief‐conception, is investigated for its resources in answering the question whether knowledge is an internal or an external relation between a person and a believed proposition. There are difficulties in each answer which (...) can be partially resolved by analysing knowledge in terms of betting. (shrink)

At times decisions are made in the field of genetics that are presented as if the ethical debates have been adequately treated and so all moral considerations have been addressed, when the truth is very different. Nor is it always easy or desirable to separate the ethical, legal and social questions posed by new developments. The impact of developments in genetic science upon communities is one field of enquiry that envelops each of these areas.This paper explores the impact of genetics (...) upon communities through focusing, in particular, upon certain developments in reproductive science. After introducing core issues and technologies, it discusses particular ethical concerns in relation to the ‘shadow’ of eugenics over such developments, before exploring the role of legislative debates and procedures in transforming social attitudes, values and hence norms. It then turns to consider debates concerning the ‘quality of life ethic’ now prevalent in healthcare, and moves on to discuss the issue of genetic discrimination – focusing, in particular, upon discrimination against disabled persons as a representative instance of the actual ethical and social/communitarian implications of the foregoing. It ends by highlighting the need to discern the ways in which the ethics of genetics is presently shaped and practised in order to discern better the particular social and communitarian implications of certain technological advances.

Quand on compare l' Optique d'Ibn al-Haytham à celle de Ptolémée, on rencontre des innovations à coup sûr capitales, et qui chacune mériterait une analyse particulière: étude expérimentale de la propagation rectiligne de la lumière, nouvelle théorie de la vision fondée sur la réception dans l'œil de rayons lumineux, recherche du lien entre l'anatomie de 1'œil et sa fonction optique, preuve expérimentale que la réfraction joue un rôle important dans la vision, et j'en passe: les dimensions d'un article de revue (...) n'y suffiraient pas. Aussi bien mon but est-il plus global et plus synthétique. Il consiste à tenter de faire le point sur ce qu'est devenue, après Ibn al-Haytham, l'insertion de l'optique dans le système des savoirs qui lui sont connectès, en comparant cette insertion à ce qu'elle était au temps de Ptolémée, c'est-à-dire dans l'œuvre de référence reçae et travaillée par lui.
