Global Prescriptions scrutinizes the movement to export a U.S.-oriented version of the " rule of law," found in the activities of philanthropic foundations, the World Bank, the U.S. Agency for International Development, and several other developmental organizations. Yves Dezalay and Bryant G. Garth have brought together a group of scholars from a variety of disciplines--anthropology, economics, history, law, political science, and sociology--to create tools for understanding this movement. Comprised of two sections, the volume first develops theoretical perspectives key to an (...) understanding of the production and impact of new "global legal prescriptions." The second part shifts attention to the national importation of these legal orthodoxies. The scholars provide a diverse set of sophisticated approaches, both to the circumstances promoting the production of these prescriptions and to the limitations of the prescriptions in the different national settings. Thus, Global Prescriptions provides a unique treatment for readers interested in globalization generally or the potential spread of the "rule of law" in particular. This volume will intrigue scholars and students interested in a political science, economics, history, anthropology, law, and sociology.

Abstract Context: Established in 1997, Summa Health System’s Medical Ethics Committee (EC) serves as an educational, supportive, and consultative resource to patients/families and providers, and serves to analyze, clarify, and ameliorate dilemmas in clinical care. In 2009 the EC conducted its 100th consult. In 2002 a Palliative Care Consult Service (PCCS) was established to provide supportive services for patients/families facing advanced illness; enhance clinical decision-making during crisis; and improve pain/symptom management. How these services affect one another has thus far been (...) unclear. Objectives: This study describes EC consults: types, reasons, recommendations and utilization, and investigates the impact the PCCS may have on EC consult requests or recommendations. Methods: Retrospective reviews of 100 EC records explored trends and changes in types of consults, reasons for consults, and EC recommendations and utilization. Results: There were 50 EC consults each in the 6 years pre- and post-PCCS. Differences found include: (1) a decrease in number of reasons for consult requests (133–62); (2) changes in top two reasons for EC consult requests from ‘Family opposed to withdrawing life-sustaining treatment (LST)’ and ‘Patient capacity in question’ to ‘Futility’ and ‘Physician opposed to providing LST’; (3) changes in top two recommendations given by the EC from ‘Emotional Support for Patient/Family’ and ‘Initiate DNR Order’ to ‘Comfort Care’ and ‘Withdraw Treatment.’ Overall, 88% of recommendations were followed. Conclusion: PCCS availability and growth throughout the hospital may have influenced EC consult requests. EC consults regarding family opposition to withdrawing LST and EC recommendations for patient/family support declined.

It is argued that at the center of Hegel’s phenomenology of consciousness is the notion that experience is shaped by identification and sacrifice. Experience is the process of self-constitution and self-transformation of a self-conscious being that risks its own being. The transition from desire to recognition is explicated as a transition from the tripartite structure of want and fulfillment of biological desire to a socially structured recognition that is achieved only in reciprocal recognition, or reflexive recognition. At the (...) class='Hi'>center of the Hegelian notion of selfhood is thus the realization that selves are the locus of accountatibility. To be a self, it is concluded, is to be the subject of normative statuses that refer to commitments; it means to be able to take a normative stand on things, to commit oneself and undertake responsibilities. Key Words: commitments • desire • experience • G.W.F.Hegel • identity • recognition • risk • sacrifice • self-consciousness • self-constitution. (shrink)
By the early 1970s, and continuing through 2001, David Lewis and Saul Kripke had taken over W.V.O. Quine’s leadership in metaphysics, epistemology, philosophy of language, and philosophical logic in the English-speaking world. Quine, in turn, had inherited his position in the early 1950s from Rudolf Carnap, who had been the leading logical positivist -- first in Europe, and, after 1935, in America. A renegade positivist himself, Quine eschewed apriority, necessity, and analyticity, while (for a time) adopting a holistic version of (...) verificationism. Like Carnap, he placed philosophical logic and the philosophy of science at the center of philosophy. (shrink)
Under the clear and thoughtful editorship of Ruiping Fan, The Renaissance of Confucianism in Contemporary China provides new and highly substantive insights into the emergence of a renewed, relevant, and perceptively engaged Confucianism in 21st century China. Through the vibrantly diverse essays contained in this volume, and in cogent overview through Fan’s introduction, one learns that Confucianism is thoroughly misunderstood, if it is seen only through Western lenses. It cannot be absorbed into that rights-based “global” discourse that has been the (...) West’s troubled inheritance from the Enlightenment. Extraordinarily thoughtful Chinese voices are found in this volume that converse with each other in serious and revealing ways. Should genuine exchange continue to develop between Western thinkers and Chinese Confucians, The Renaissance of Confucianism in Contemporary China will surely be an indispensable pathway into those core issues, moral and social, that will unavoidably be encountered as China and the West advance further into the 21st century. -/- -/- Stephen A. Erickson, Professor of Philosophy and the E. Wilson Lyon Professor of the Humanities, Pomona College, USA -/- -/- The Renaissance of Confucianism in Contemporary China features an important school of Confucianism in Mainland China today, “Political Confucianism,” powerfully articulated by Jiang Qing, author of the leading article in this volume. “Political Confucianism” is unique: on the “Political” side, it rejects many core values of liberalism, the dominant political ideology in the West; and on the “Confucianism” side, it rejects the one-sided emphasis on the inner sageliness of “New Confucianism” developed in Hong Kong and Taiwan in the last century. In this volume, the programmatic essay by Jiang Qing is followed by penetrating essays, either further expanding on or critically examining various themes of Jiang’s original essay, by eminent scholars, many of whom are committed Confucians themselves. The volume concludes with an informative biography of Jiang Qing. It is a must-read for anyone who is interested in learning about the situation of Confucianism in contemporary China in particular and about Confucianism or contemporary China in general. -/- -/- Yong HUANG, Chief Editor, Dao: A Journal of Comparative Philosophy -/- This is the most important recent study of Chinese culture and political theory. It offers a rich insight into the renaissance of authentic Confucian commitments in contemporary China and the foundationally different moral and political direction that it proposes for China’s future. The essays Fan brings together tie the power of China’s rich past to the prospect of a China quite different from what the West envisages. It is a “must-read” for anyone seeking to understand China in the 21st century. -/- -/- David Solomon, W.P. and H.B. White Director of the Center for Ethics and Culture, University of Notre Dame.

Two celebrated passages in Kant center on a problem that is sometimes called the ‘availability’ of motives. One concerns the naturally sympathetic man whose mind becomes “overclouded by sorrows of his own which extinguish all sympathy with the fate of others”. Kant argues that even in this state, when he has no “inclination” to help others, he can do so, since he can act “for the sake of duty alone”.1 The other passage states that the commandment to love our (...) neighbor cannot mean that we must act from “pathological love”, that is, an emotion or feeling of love. Feeling is not under our control. We can, however, perform acts of “practical love”, that is, acts of assistance, and these acts we can perform from the motive of duty.2 One way to combine the conclusions of these two arguments is to say that for Kant the motive of duty is always ‘available’, but motives like sympathy and “pathological love” are not. One question that arises here is whether Kant drew a mistaken conclusion from the second argument. W.D. Ross seemed to think so, because he takes the argument to be completely general.3 That is, he takes Kant to have proved that no motive, including the sense of duty, is always available. Ross’ focus was on obligation-making motives. He took his view about the availability of motives, along with the principle that ‘ought’ implies ‘can’, to entail PR. (shrink)
: This paper both elaborates and interrogates the transactional model of human experience at the center of Shannon W. Sullivan's Living Across and Through Skins. In particular, it highlights the need (especially given her concerns and commitments) to supplement her account with a psychoanalytic reading of our gendered subjectivities. Moreover, it stresses the necessity to focus on such humanly important—and irreducibly somatic—phenomena as grief and eros.
From the moment of discovery, the Piltdown "fossils" were the center of controversy. Piltdown apparently provided a human fossil on English soil, a maker for the eoliths, and proof that the brain came first in human evolution and that an anatomically modern braincase was present at the beginning of the Ice Age. Every conclusion was important and controversial, and for many years it was not possible to discuss human evolution without considering Piltdown. Hundreds of papers were written about the (...) discoveries, but the problem remained. Anatomically it seemed impossible to associate the skull and jaw, but the chance association of an ape's jaw and a human skull in England seemed at least as improbable. The solution came when J.S. Weiner, Kenneth Oakley, and W.L. le Cros Clark showed that everything was fake–the bones had been stained, ape's teeth filed down, and fossils added to the assemblage to determine the antiquity. The whole matter is carefully reviewed in Weiner's The Piltdown Forgery ( 1955). (shrink)

Abstract This paper addresses the role that argumentation schemes and argument visualization software tools can play in helping to find and counter objections to a given argument one is confronted with. Based on extensive analysis of features of the argumentation in these two examples, a practical four-step method of finding objections to an argument is set out. The study also applies the Carneades Argumentation System to the task of finding objections to an argument, and shows how this system has some (...) capabilities that are especially useful.

Under the impact of cultural, economic and legislative forces the traditional role of the university health center is changing. The academic health center is rapidly evolving from a relatively undifferentiated general hospital, primarily responsible for the education of undergraduate students of medicine, into a center of clinical research, caring for very specialized mixes of patients, and having as its primary educational mission the training of subspecialists. The nature of the forces responsible for this change are analyzed, and (...) some of its possible consequences for the definition of quality health care, for the shape of medical practice and medical education, and for the allocation of resources for health care are explored. This exploration suggests that the functional separation of the medical school from the highly technical, clinical research center is inevitable. This in turn may exacerbate tensions within medicine between the physician as scientist and as healer, between curative and preventive practice and between personal and public health. Although the effects of this separation on medical education remain obscure, it has already occasioned the most comprehensive review of the medical curriculum since the time of Flexner. Out of this is likely to develop a more generalist view of the education of future physicians. (shrink)
Over the last two decades, debates over the viability of commonsense psychology have been center stage in both cognitive science and the philosophy of mind. Eliminativists have argued that advances in cognitive science and neuroscience will ultimately justify a rejection of our "folk" theory of the mind, and of its ontology. In the first half of this book Stich, who was at one time a leading advocate of eliminativism, maintains that even if the sciences develop in the ways that (...) eliminativists foresee, none of the arguments for ontological elimination are tenable. Rather than being resolved by science, he contends, these ontological disputes will be settled by a pragmatic process in which social and political considerations have a major role to play. In later chapters, Stich argues that the widespread worry about "naturalizing" psychological properties is deeply confused, since there is no plausible account of what naturalizing requires on which the failure of the naturalization project would lead to eliminativism. He also offers a detailed analysis of the many different notions of folk psychology to be found in philosophy and psychology, and argues that simulation theory, which purports to be an alternative to folk psychology, is not supported by recent experimental findings.

We advocate and share the same theoretical framework for empirical research in ethics as exemplified in Christina Bicchieri’s The Grammar of Society. Our research differs from Bicchieri’s in our approach to experimentation: where she relies on lab experiments, we have constructed an experimental platform based on an internet survey instrument; where she relies on rational reconstructions, we do not. In this paper we focus on four contrasts in our methods: (1) we provide a space to explore ethical influence and norm (...) transmission between participants, belief and choice revision, and reputation over time; (2) we provide ways for participants to expand the context of their and others’ decisions; (3) we focus on more realistic ethical decisions than is allowed by games; and (4) we explain why Bicchieri’s method of rational reconstructions presents challenges to her theory of social norms. Our methods are complementary to Bicchieri’s, and together we can work toward developing more comprehensive empirically informed ethics. †To contact the authors, please write to Peter Danielson, W.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.
Abstract Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a bounded cognizer (...) to true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings.

A two strain HIV/AIDS model with treatment which allows AIDS patients with sensitive HIV-strain to undergo amelioration is presented as a system of non-linear ordinary differential equations. The disease-free equilibrium is shown to be globally asymptotically stable when the associated epidemic threshold known as the basic reproduction number for the model is less than unity. The centre manifold theory is used to show that the sensitive HIV-strain only and resistant HIV-strain only endemic equilibria are locally asymptotically stable when the associated (...) reproduction numbers are greater than unity. Qualitative analysis of the model including positivity, boundedness and persistence of solutions are presented. The model is numerically analysed to assess the effects of treatment with amelioration on the dynamics of a two strain HIV/AIDS model. Numerical simulations of the model show that the two strains co-exist whenever the reproduction numbers exceed unity. Further, treatment with amelioration may result in an increase in the total number of infective individuals (asymptomatic) but results in a decrease in the number of AIDS patients. Further, analysis of the reproduction numbers show that antiretroviral resistance increases with increase in antiretroviral use. (shrink)
‘Learning to be job ready’ (L2BJR) was a pilot scheme involving 16 long-term unemployed people from a range of backgrounds being offered a 6-month paid placement within the care department of a city council in Northern England. The project was based on a partnership with the largest college in the city specialising in post-16 education and training for residents and employees. The college targeted people as potential candidates for the programme through their prior attendance on or interest in care courses (...) at the college, rather than the council employing more traditional methods of recruitment. Surveys, focus groups and interviews were utilised to capture the views and experiences of the participants, project workers and line managers, and also evidence of the project’s impact on service delivery in the care department. The article adds to our conceptual and practical knowledge of corporate social responsibility (CSR) in the public sector in three distinct ways. From a social and business perspective, the findings of the research highlight a potentially more robust strategy for matching long-term unemployed citizens to training and job opportunities in the public sector than is otherwise possible through the more conventional route of the job centre. Secondly, through this approach and with appropriate pre-training, a greater understanding of and empathy for the service users can be developed in the new organisational members, strengthening the subsequent ethical delivery and quality of the service. Finally, a re-conceptualisation of Carroll’s influential model of CSR, which also specifically incorporates the ethical and social inclusion duties of public sector organisations not only as service providers but also as potential employers, offers a more tailored paradigm for understanding this unique yet under-researched element of CSR theory and practice.

OBJECTIVE: To describe the issues faced, and how they were addressed, by the University of Toronto Critical Care Medicine Program/Joint Centre for Bioethics Task Force on Appropriate Use of Life-Sustaining Treatment. The clinical problem addressed by the Task Force was dealing with requests by patients or substitute decision makers for life-sustaining treatment that their healthcare providers believe is inappropriate. DESIGN: Case study. SETTING: The University of Toronto Joint Centre for Bioethics/Critical Care Medicine Program Task Force on Appropriate Use of Life-Sustaining (...) Treatment. PARTICIPANTS: The 24-member Task Force included physician and nursing leaders from five critical care units, bioethicists, a legal scholar, a health administration expert, a social worker, and a hospital public relations professional. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Our specific lessons learned include a) a policy focus on process; b) use of a negotiation and mediation model, rather than a hospital ethics committee model, for this process; and c) the policy development process is itself a negotiation, so we recommend equal involvement of interested groups including patients, families, and the public. CONCLUSIONS: This article describes the key issues faced by the Task Force while developing its policy. It will provide a useful starting point for other groups developing policy on appropriate use of life-sustaining treatment. (shrink)
Adults and infants display a robust ability to perceive the unity of a center-occluded object when the visible ends of the object undergo common motion (e.g. Kellman, P.J., Spelke, E.S., 1983. Perception of partly occluded objects in infancy. Cognitive Psychology 15, 483±524). Ecologically oriented accounts of this ability focus on the primacy of motion in the perception of segregated objects, but Gestalt theory suggests a broader possibility: observers may perceive object unity by detecting patterns of synchronous change, of which (...) common motion is a special case. We investigated this possibility with observations of adults and 4-month-old infants. Participants viewed a center-occluded object whose visible surfaces were either misaligned or aligned, stationary or moving, and unchanging or synchronously changing in color or bright- ness in various temporal patterns (e.g. ¯ashing). Both alignment and common motion con- tributed to adults' perception of object unity, but synchronous color changes did not. For infants, motion was an important determinant of object unity, but other synchronous changes and edge alignment were not. When a stationary object with aligned edges underwent syn- chronous changes in color or brightness, infants showed high levels of attention to the object, but their perception of its unity appeared to be indeterminate. An inherent preference for fast over slow ¯ash rates, and a novelty preference elicited by a change in rate, both indicated that infants detected the synchronous changes, although they failed to use them as information for object unity. These ®ndings favor ecologically oriented accounts of object perception in which surface motion plays a privileged role. Ó 1999 Elsevier Science B.V. All rights reserved. (shrink)
Let AC be a ray coming from the medium DC into the medium CE, and let the density of the former to the latter be as d to e. It is asked, how should the ray ACB be directed so that it is the easiest path of all, or that (AC x d) + (CB x e) is a minimum. Let DC = l, and EC = m. It is given also that FG = f, and let AD = FC (...) = x, CG = EB = f – x. Therefore, AC = √(l2 + x2) and CB = √(m2 + f2 +x2 – 2fx). 2 It will then be the case that d√(l2 + x2) + e√(m2 + f2 + x2 – 2fx is equal to a minimum. Therefore, through my method of tangents it is the case that: (2dx/(√(l2 +x2)(AC))) + ((2ex -2ef)/ (√(m2 +f2 +x2 +2fx)(BC))) = 0. That is, it will be the case that AC/BC = dx/e(f-x). Now if we suppose that AC and BC are equal, it will be the case that f – x is to x, as d to e. Therefore, if a circle, with its center at C, is described by the ray CA or CB, AD or “x,” – the sine of the angle of incidence – will be to BE or “f – x,” – the sine of the angle of refraction – as e, the density of the medium of refraction, will be to d, the density of the medium of incidence, that is, the sines of the angles will be in reciprocal relation to the mediums or densities.

Although much evidence indicates that young infants perceive unitary objects by analyzing patterns of motion, infantsÕ abilities to perceive object unity by analyzing Gestalt properties and by integrating distinct views of an object over time are in dispute. To address these controversies, four experiments investigated adultsÕ and infantsÕ perception of the unity of a center-occluded, moving rod with misaligned visible edges. Both alignment information and depth information affected adultsÕ and infantsÕ perception of object unity in similar ways, and infants (...) perceived object unity by integrating information about object features over time. However, infants perceived a moving, misaligned, three-dimensional object as indeterminate in its connectedness, whereas adults perceived it as connected behind the occluder. These findings indicate that the effectiveness of common motion in specifying unified surfaces across an occluder is reduced by misalignment of edges. Alignment information enhances perception of object unity either by serving directly as information for unity or by optimizing the detectability of motion-carried information for unity. In addition, young infants are able to retain information about edge orientation over short intervals in determining connectedness via a process of spatiotemporal integration.

The Phoenician Women, Euripides' peculiar retelling and refashioning of the Theban myth, offers a portrait of Antigone before she becomes the actor we mostly know today from Sophocles' play. In this under-studied Greek tragedy, Euripides portrays the political and epistemological dissolution that allows for Antigone's appearance in public. Whereas Sophocles' Antigone appears on stage ready to confront Creon with her appeal to the universal unwritten laws of the gods and later dissolves into the female lamenting a lost (...) womanhood, Euripides' Antigone experiences the opposite journey, thereby offering insights into the conditions that allow for her exposure in the political arena. A speech by Eteocles at the center of the play questions the existence of absolutes, calls injustice beautiful, and opens the door for Antigone's entrance into the public sphere. With this speech Eteocles challenges us to consider the conditions of political openness in the modern age. (shrink)
A "recent consensus" has emerged in Locke studies that has sought to place theology at the center of Locke's political philosophy, insisting that the validity and cogency of Locke's political conclusions cannot be substantiated independently of the theology that resides at their foundation. This paper argues for the need to distance Locke from God, claiming that not only can we "bracket" the normative conclusions of Locke's political philosophy from their theological foundations, but that this was in fact Locke's own (...) intention, intent as he was to justify these conclusions to a diverse political audience often divided by faith. In other words, this "recent consensus" in Locke studies is premised on an erroneous understanding of Locke's political philosophy, even as advanced by Locke himself. Locke's own philosophical discourse bears witness to the very "bracketing" of his political conclusions from their theological foundations that these Locke scholars claim is impossible. (shrink)
Apical cells are universally present in lower plants and their description has been mostly viewed morphologically as single-celled meristems. This study attempts to demonstrate that the roles of apical cells and more generally of meristems collectively are (a) often the proliferative source of all cells in a plant, (b) sometimes a formative centre in histogenesis and organogenesis and (c) always a regulatory site. As a proliferative centre it occurs as a series of apical cells through a mitotic lineage by unequal (...) divisions which includes a rotational pattern to form cells distributed according to the symmetry of its organ. As a formative centre it determines leaf arrangement in mosses and leafy liverworts as well as the root cap and gametophyte cushion in ferns. It appears initially to determine the type of organ and later the organ determines the type of apical cells within. As a regulatory centre it activates distal secondary cells to proliferate as well as inhibiting neighbouring cells from becoming apical cells to preserve the identity of an organ during its development.Based on these three roles by which apical cells can be recognized an argument can be drafted that seed plants may have apical cells, although morphologically indistinguishable from other cells, singularly or in batteries instead of possessing the traditionally described multicellular meristems.

Le monde se révèle à l'homme, comme matière, temps et esprit. L'on sait à présent que considérés dans l'espace et le temps, la terre est d'une extrême petitesse et l'homme un être éphémère. Une conception du monde qui prendrait l'homme pour centre et partirait de lui ne donnerait donc aucune garantie de probabilité. Pourtant elle est assez générale, accoutumés comme nous sommes à juger d'après les perceptions grossières des sens, qui trop souvent nous induisent en erreur. Selon les physiciens, la (...) formule mathématique réunissant les coördonnées du temps et de l'espace, serait la plus conforme à la représentation du monde matériel. Nous avançons ici l'hypothèse que le monde matériel répond effectivement à cette conception, et qu'il est donc un monde plongé dans un repos éternel, dans lequel nous voyageons, pour ainsi dire, avec notre temps. Grâce à cette hypothèse, la causalité, le miracle, la prévoyance de l'avenir, s'expliquent plausiblement. Manifestement le troisième principe, l'esprit, est à la fois en interaction avec la matière et indépendante d'elle (p.e. la télépathie). Cette action réciproque suppose une parenté partielle entre l'esprit et la matière. C'est pourquoi nous proposons une seconde hypothèse: l'esprit est une "facies" de la matière qui reste en dehors de la rigidité du monde considéré comme espace et temps. On a toujours considéré ces éléments spirituels comme étant des êtres spirituels, mais leur aspect anthropomorphique nous empêche de croire à leur existence réelle. Si nous identifions la partie spirituelle du corps humain avec l'homme spirituel, le problème du libre arbitre s'explique avec clarté. Seul le procès spirituel du libre arbitre est vraiment libre, mais la volonté ne peut réaliser aucun changement dans la substance purement matérielle. La conception d'une àme se logeant dans le corps matériel comme dans une maison, et qui par ses actions détermine sa demeure future ne s'accorde pas avec l'hypothèse du monde matériel-et-temporel-en-repos. Suivant nos conceptions humaines, nous avons imaginé des êtres spirituels animés d'une volonté libre. Mais alors il faut supposer une unité spirituelle supérieure, qui considère et qui décide. Or, cette conception étant anthropomorphique il est admissible qu'elle soit la véritable figuration du monde. La solution de ce problème pourrait être trouvée par une troisième hypothèse" selon laquelle il existerait un monde supérieur, dans lequel le monde-du-temps-et-de-l'espace fusionne avec un temps supérieur, auquel le nom de "temps spirituel" serait approprié. Seul, ce monde supérieur plongé dans un repos éternel peut nous expliquer d'une façon convaincante l'univers. Un monde d'une essence et d'une invariabilité éternelles, dans lequel le temps, capable d'agir pas des voies infiniment variées, introduit des événements innombrables, les processus spirituels étant effectués par le temps spirituel, les événements matériels par ce que nous sommes habitués à appeler "le temps".

There is a fundamental inconsistency in Western society’s treatment of non-human animals on the one hand, and of human foetuses on the other. While most Western countries allow the butchering of animals and their use in experimentation, this must occur under carefully controlled conditions that are intended to minimize their pain and suffering as much as possible. At the same time, most Western countries permit various abortion methods without similar concerns for the developing fetus. The only criteria for deciding which (...) abortion method is used centre in the stage of the pregnancy, the size of the fetus, the health of the pregnant woman and the physician’s preference. This is out of step with the underlying ethos of animal cruelty legislation, cannot be justified ethically and should be rectified by adjusting abortion methods to the capacity of the fetus to experience nociception and/or pain.
