In the 4 1/2 to 5 days between fertilization and implantation, the mouse conceptus must gain the abilities to implant and produce an embryo. Each of these is the sole developmental responsibility of one of two cell types forming the blastocyst, trophectoderm and inner cell mass (ICM), respectively. Trophectoderm is a polarized transporting epithelium while the ICM is an aggregate of non‐epithelial pluripotent stem cells. These two cell types originate from the division of polar blastomeres when their cleavage furrows parallel (...) their apical surfaces. Blastomeres polarize in response to asymmetric cell–cell contact, and understanding the mechanism of this induction is regarded as the key to understanding the origin of trophectoderm and ICM. Here we propose a model based on transcellular ion current loops for the induction of cell polarity during the development of the first epithelium, trophectoderm. (shrink)

Preface Phillip R. Sloan, Gerald McKenny, Kathleen Eggleson pp. xiii-xviii In November of 2009, the University of Notre Dame hosted the conference “Darwin in the Twenty-First Century: Nature, Humanity, and God.‘ Sponsored primarily by the John J. Reilly Center for Science, Technology, and Values at Notre Dame, and the Science, Theology, and the Ontological Quest project within the Vatican Pontifical... 1. Introduction: Restructuring an Interdisciplinary Dialogue Phillip R. Sloan pp. 1-32 Almost exactly fifty years before the Notre Dame conference, (...) the world’s largest centenary commemoration of Darwin’s legacy was held at nearby University of Chicago. This event, organized by a committee spearheaded by University of Chicago anthropologist Sol Tax, drew nearly 2,500 registrants. In attendance were the primary leaders... Part 1. Nature 2. Evolution through Developmental Change: How Alterations in Development Cause Evolutionary Changes in Anatomy Scott F. Gilbert pp. 35-60 For the past half-century, the mechanisms of evolution have been explained by the fusion of genetics and evolutionary biology called “the Modern Synthesis.‘ The tenets of the Modern Synthesis have been generally formulated as such: 1. There is genetic variation within the population. 2. There is competition... 3. The Evolution of Evolutionary Mechanisms: A New Perspective Stuart A. Newman pp. 61-89 The Modern Evolutionary Synthesis, based on Charles Darwin’s concept of natural selection in conjunction with a genetic theory of inheritance in a population-based framework, has been, for more than six decades, the dominant scientific perspective for explaining the diversity of living organisms. In recent years, however, with the growth... 4. The Evolvability of Organic Forms: Possible, Likely, and Unlikely Change from the Perspective of Evolutionary Developmental Biology Alessandro Minelli pp. 90-115 Confronted with the extraordinary diversity of animal form, we can ask questions about function and adaptation. How does this animal move? How does it feed? How does it defend itself from its enemies? But we can also ask questions about development, reproduction, and heredity. What mechanisms produce these forms? How are these... 5. Accident, Adaptation, and Teleology in Aristotle and Darwinism David J. Depew pp. 116-143 Charles Darwin framed the Origin of Species to meet criteria for inductive science set out by John Herschel in his Preliminary Discourse on the Study of Natural Philosophy. Accordingly, he was distraught when he learned that Herschel, to whom he had sent a copy of his newly published book, was not... 6. The Game of Life Implies Both Teleonomy and Teleology Gennaro Auletta, Ivan Colagè, Paolo D’Ambrosio pp. 144-164 The present contribution is mainly aimed at suggesting the importance of teleonomy and teleology as explanatory mechanisms in biology in the light of recent achievements in the field, and at showing that they play an actual and relevant role in the realm of life. The issue of finality in biology still provokes lively debates in the... Part 2. Humanity 7. Humanity’s Origins Bernard Wood pp. 167-181 One of Charles Darwin’s many achievements is that he began the process of converting the Tree of Life from a religious metaphor into a biological reality. All types of living organisms, be they animals, plants, fungi, bacteria, or viruses, are at the end of twigs that reach the surface of the Tree of Life, and all the types of organisms... 8. Darwin’s Evolutionary Ethics: The Empirical and Normative Justifications Robert J. Richards pp. 182-200 In the increasingly secular atmosphere of the nineteenth century, intellectuals grew wary of the idea that nature had any moral authority. In an earlier age, one might have looked upon the dispositions of nature as divinely sanctioned, and thus one could call upon natural law to ground moral judgment. Certain behaviors, for instance, might have... 9. Crossing the Milvian Bridge: When Do Evolutionary Explanations of Belief Debunk Belief? Paul E. Griffiths, John S. Wilkins pp. 201-231 Two traditional targets for evolutionary skepticism are religion and morality. Evolutionary skeptical arguments against religious belief are continuous with earlier genetic arguments against religion, such as that implicit in David Hume’s Natural History of Religion. Evolutionary arguments are also... 10. Questioning the Zoological Gaze: Darwinian Epistemology and Anthropology Phillip R. Sloan pp. 232-266 This quotation from Darwin’s Descent of Man illuminates an under-explored issue in Darwin’s work---not the issue of evolutionary ethics itself, but the epistemology of experience assumed in his work, and the consequences of his application of this “zoological gaze‘ to human beings. I will term this epistemological stance in this chapter “natural historical... Part 3. God 11. Evolution and Catholic Faith John O’Callaghan pp. 269-298 To begin to examine the relation of orthodox Catholic Christian faith to evolutionary theory and the question of human origins, consider words of the fourth pope, St. Clement: Let us fix our gaze on the Father and Creator of the whole world, and let us hold on to his peace and blessings, his splendid and surpassing... 12. After Darwin, Aquinas: A Universe Created and Evolving William E. Carroll pp. 299-337 At the 2000 Jubilee Session for scientists, held at the Vatican in May of that year, Archbishop Józef Życiński offered an eloquent assessment of contemporary discourse on the relationship between the natural sciences and theology. He ended his address with the comment that what is needed today is a new Thomas Aquinas. I remember... 13. Evolutionary Theism and the Emergent Universe Józef Życiński pp. 338-354 The 150th anniversary of the publication of Charles Darwin’s The Origin of Species has been celebrated in the context of an animated debate concerning both scientific and philosophical issues implied by the theory of evolution.1 One finds a deep diversity of attitudes, both methodological and semantic, in the current debates on evolutionary... 14. Beyond Separation or Synthesis: Christ and Evolution as Theodrama Celia Deane-Drummond pp. 355-380 The fervor with which popular discourse on science and religion has continued to bubble up in the anniversary year celebrating Darwin’s achievements shows that the publically perceived conflict between science and religion will not go away. Academic discussion on such matters is therefore not just peripheral to cultural concerns but takes... Part 4. Past and Future Prospects 15. Imagining a World without Darwin Peter J. Bowler pp. 383-403 What would have happened if Charles Darwin had not lived to write On the Origin of Species? Perhaps his bad health caused the early death he feared, or maybe he fell overboard while on the voyage of the Beagle. Would the world have still experienced the Darwinian Revolution under another name, or would the history of science, and... 16. What Future for Darwinism? Jean Gayon pp. 404-423 What future for Darwinism? I will propose some criteria for exploring this question in the domains of both evolutionary biology and the human sciences. Do not expect me to tell you where we will stand thirty years from now. It will be enough to identify a few general tendencies. For the sake of brevity, I will not devote a preamble to explain...

In December 1984 Angela Weir and Elizabeth Wilson, two founding members of Feminist Review, published an article assessing contemporary British feminism and its relationship to the left and to class struggle. They suggested that the women's movement in general, and socialist-feminism in particular, had lost its former political sharpness. The academic focus of socialist-feminism has proved more interested in theorizing the ideological basis of sexual difference than the economic contradictions of capitalism. Meanwhile the conditions of working-class and black women have (...) been deteriorating. In this situation, they argue, feminists can only serve the general interests of women through alliance with working-class movements and class struggle. Weir and Wilson represent a minority position within the British Communist Party (the CP), which argues that ‘feminism’ is now being used by sections of the left, in particular the dominant ‘Eurocommunist’ left in the CP, to justify their moves to the right, with an accompanying attack on traditional forms of trade union militancy. Beatrix Campbell, who is aligned to the dominant position within the CP, has been one target of Weir and Wilson's criticisms. In several articles from 1978 onwards, and in her book Wigan Pier Revisited, Beatrix Campbell has presented a very different analysis of women and the labour movement. She has criticized the trade union movement as a ‘men's movement’, in the sense that it has always represented the interests of men at the expense of women. And she has described the current split within the CP as one extending throughout the left between the politics of the ‘old’ and the ‘new’: traditional labour movement politics as against the politics of those who have rethought their socialism to take into account the analysis and importance of popular social movements – in particular feminism, the peace and anti-racist movements. In reply to this debate, Anne Phillips has argued that while women's position today must be analysed in the context of the capitalist crisis, it is not reducible to the dichotomy ‘class politics’ versus ‘popular alliance’. Michèle Barrett, in another reply to Weir and Wilson, has argued that they have presented a reductionist and economistic approach to women's oppression, which caricatures rather than clarifies much of the work in which socialist-feminists have been engaged. To air these differences between socialist-feminists over the question of feminism and class politics, and to see their implications for the women's movement and the left, Feminist Review has decided to bring together the main protagonists of this debate for a fuller, more open discussion. For this discussion Feminist Review drew up a number of questions which were put to the participants by Clara Connolly and Lynne Segal. (Michèle Barrett was present in a personal capacity.) They cover the recent background to socialist-feminist politics, the relationship of feminism to Marxism, the role of feminists in le ft political parties and the labour movement, the issue of racism and the prospects for the immediate future. The discussion was lengthy and what follows is an edited version of the transcript. (shrink)

In this paper, I explore the relationship between naturalism and transcendental idealism in Fichte. I conclude that Fichte is a near-naturalist, akin to Baker, Lynne Rudder (2017). “Naturalism and the idea of nature,” Philosophy 92 (3): 333–349. A near-naturalist is one whose position looks akin to the naturalist in some ways but the near-naturalist can radically differ in metaphilosophical orientation and substantial commitment. This paper is composed of three sections. In the first, I outline briefly what I take transcendental idealism (...) to be, as well as some differences in types of naturalism, and how this maps on to Fichte. In the second, I give an exegesis of Fichte’s key arguments in the Later Jena period, which are important for the question of his relationship to naturalism. In the third, I continue the exegesis with a discussion of Fichte’s conception of God, and conclude that these arguments support a near-naturalist reading of Fichte. (shrink)

Recent years have witnessed a growing concern that terminally illpatients are needlessly suffering in the dying process. This has ledto demands that physicians become more attentive in the assessment ofsuffering and that they treat their patients as `whole persons.'' Forthe most part, these demands have not fallen on deaf ears. It is nowwidely accepted that the relief of suffering is one of the fundamentalgoals of medicine. Without question this is a positive development.However, while the importance of treating suffering has generally (...) beenacknowledged, insufficient attention has been paid to the question ofwhether different types of terminal suffering require differnt responsesfrom health care professionals. In this paper we introduce a distinctionbetween two types of suffering likely to be present at the end of life,and we argue that physicians must distinguish between these types if theyare to respond appropriately to the suffering of their terminally illpatients. After introducing this distinction and explaining its basis,we further argue that the distinction informs a (novel) principle ofproportionality, one that should guide physicians in balancing theircompeting obligations in responding to terminal suffering. As weexplain, this principle is justified by reference to the intereststerminally ill patients have in restoration, as well as in therelief of suffering, at the end of life. (shrink)

INTRODUCTION Reopening a Discussion The empiricist-derived epistemology that has directed most social and natural scientific inquiry for the last three ...

Recent studies lead to the paradoxical conclusion that the act of affirming one's egalitarian or prosocial values and virtues might subsequently facilitate prejudiced or self-serving behavior, an effect previously referred to as ?moral credentialing.? The present study extends this paradox to the domain of academic misconduct and investigates the hypothesis that such an effect might be limited by the extent to which misbehavior is rationalizable. Using a paradigm designed to investigate deliberative and rationalized forms of cheating (von Hippel, Lakin, & (...) Shakarchi, 2005), we found that when participants had credentialed themselves (vs. a nonclose acquaintance) via a set of hypothetical moral dilemmas, they were more likely to cheat on a subsequent math task, but only if cheating was highly rationalizable. When cheating was difficult to rationalize, moral credentialing had almost no impact on cheating. (shrink)

Imprecise definition of key terms in the “public participation” domain have hindered the conduct of good research and militated against the development and implementation of effective participation practices. In this article, we define key concepts in the domain: public communication, public consultation, and public participation. These concepts are differentiated according to the nature and flow of information between exercise sponsors and participants. According to such an information flow perspective, an exercise’s effectiveness may be ascertained by the efficiency with which full, (...) relevant information is elicited from all appropriate sources, transferred to all appropriate recipients, and combined to give an aggregate/consensual response. Key variables that may theoretically affect effectiveness—and on which engagement mechanisms differ—are identified and used to develop a typology of mechanisms. The resultant typology reveals four communication, six consultation, and four participation mechanism classes. Limitations to the typology are discussed, and future research needs identified.

Why equality cannot be conditional on a shared human “nature” but has to be for all For centuries, ringing declarations about all men being created equal appealed to a shared human nature as the reason to consider ourselves equals. But appeals to natural equality invited gradations of natural difference, and the ambiguity at the heart of “nature” enabled generations to write of people as equal by nature while barely noticing the exclusion of those marked as inferior by their gender, race, (...) or class. Despite what we commonly tell ourselves, these exclusions and gradations continue today. In Unconditional Equals, political philosopher Anne Phillips challenges attempts to justify equality by reference to a shared human nature, arguing that justification turns into conditions and ends up as exclusion. Rejecting the logic of justification, she calls instead for a genuinely unconditional equality. Drawing on political, feminist, and postcolonial theory, Unconditional Equals argues that we should understand equality not as something grounded in shared characteristics but as something people enact when they refuse to be considered inferiors. At a time when the supposedly shared belief in human equality is so patently not shared, the book makes a powerful case for seeing equality as a commitment we make to ourselves and others, and a claim we make on others when they deny us our status as equals.

In the United States there is an increasing tendency to view the only educational research worthy of federal funding as that which is designed as an experiment using randomised controls. One of the foundational assumptions underlying this research design is that the results of such research are meant to be generalisable beyond any particular research study. The purpose of this paper is to historicise the assumption of generalisability by explaining the ways in which it is a particularly modern research project. (...) By historicising generalisability, I show the ways in which the current research standards are products of culturally specific historical circumstances. In other words, generalisability is a local phenomenon and not generalisable to other times and places. (shrink)

This important new book takes as its points of departure two questions: What is the nature of valuing? and What morality can be justified in a society that deeply disagrees on what is truly valuable? In Part One, the author develops a theory of value that attempts to reconcile reason with passions. Part Two explores how this theory of value grounds our commitment to moral action. The author argues that rational moral action can neither be seen as a way of (...) simply maximising one's own values, nor derived from reason independent of one's values. Rather, our commitment to the moral point of view is presupposed by our value systems. The book concludes with a defense of liberal political morality. (shrink)

This paper suggests that the appearance of circularity in descartes' arguments is due to a lack of precision in his statements of them, Rather than to any flaw in his reasoning. The clear and distinct perceptions presupposed in the demonstrations of the existence of God are not the same as those whose reliability depends upon the existence of god. He is presupposing the reliability only of those clear and distinct perceptions which are known through the light of nature and have (...) metaphysical certainty in that they cannot be imagined false even on the demon hypothesis. And the only clear and distinct perceptions whose reliability he is demonstrating are those which are not known through the light of nature with metaphysical certainty but are subject to metaphysical doubt on the demon hypothesis, Even though they have moral or psychological certainty.

Defence cases with an escalatory structure, in which the levels of violence between aggressor and defender start out as minor and then become major, even lethal, raise sharp problems for defence theory, and for our understanding of the conditions of defence: proportionality, necessity, and imminence. It is argued here that defenders are not morally required to withdraw from participation in these cases, and that defensive escalations do not offend against any of the conditions of defence, on an adequate understanding of (...) them. No plausible interpretation of proportionality or necessity excludes defensive permissions in escalatory cases. Moreover, the structure of escalatory defensive cases also sheds useful light on permissible responses to conditional deadly threats. This is because we can analyse conditional deadly threats as disguised cases of escalation. Because defensive resistance is permissible in escalatory cases, it is also permissible in cases involving conditional deadly threats. (shrink)

With human language, the same utterance can have different meanings in different contexts. Nevertheless, listeners almost invariably converge upon the correct intended meaning. The classic Gricean explanation of how this is achieved posits the existence of four maxims of conversation, which speakers are assumed to follow. Armed with this knowledge, listeners are able to interpret utterances in a contextually sensible way. This account enjoys wide acceptance, but it has not gone unchallenged. Specifically, Relevance Theory offers an explicitly cognitive account of (...) utterance interpretation that presents a radical challenge to the neo‐Gricean paradigm. Evolutionary considerations are one way in which we can choose between competing theories. A simple game‐theoretic model of the evolution of communication is presented, and it is used to derive a number of basic qualities that will be satisfied by all evolved communication systems. These qualities are observed to precisely predict the foundational principles of Relevance Theory. The model thus provides biological support for that enterprise in general, and for the plausibility of the cognitive mechanisms that it describes in particular. (shrink)

: "Clinical pragmatism" is an important new method of moral problem solving in clinical practice. This method draws on the pragmatic philosophy of John Dewey and recommends an experimental approach to solving moral problems in clinical practice. Although the method may shed some light on how clinicians and their patients ought to interact when moral problems are at hand, it nonetheless is deficient in a number of respects. Clinical pragmatism fails to explain adequately how moral problems can be solved experimentally, (...) it underestimates the relevance and importance of judgment in clinical ethics, and it presents a questionable account of the role that moral principles should play in moral problem solving.

This paper addresses the role of categories and dimensions in the classification of psychopathology. While psychopathology does not sort itself out neatly into natural categories, we do find rough, symptom-based groupings that, through refinement, become diagnostic categories. Given that these categories suffer from comorbidity, uncertain boundaries, and excessive “unspecified disorder” diagnoses, there has been a move toward refining the diagnoses with dimensional measures. The paper traces efforts both to improve the diagnostic categories with validators that allow at least partial validity (...) and to introduce dimensional measures into the diagnostic manual. Drawing from the philosophical pragmatism of Charles Sanders Peirce, William James, and John Dewey, which emphasizes the practical, effect-sensitive consequences of a theory along with an emphasis on empirical evidence and the progressive, probabilistic character of knowledge, the paper argues that these efforts must be guided both by scientific validity and clinical utility.

Over many centuries, the homing pigeon has been selectively bred for returning home from a distant location. As a result of this strong selective pressure, homing pigeons have developed an excellent spatial navigation system. This system passes through the hippocampal formation, which shares many striking similarities to the mammalian hippocampus; there are a host of shared neuropeptides, interconnections, and its role in the storage and manipulation of spatial maps. There are some notable differences as well: there are unique connectivity patterns (...) and spatial encoding strategies. This review summarizes the comparisons between the avian and mammalian hippocampal systems, and the responses of single neurons in several general categories: location and place cells responding in specific areas, path and goal cells responding between goal locations, context-dependent cells that respond before or during a task, and pattern, grid, and boundary cells that increase firing at stable intervals. Head-direction cells, responding to a specific compass direction, are found in mammals and other birds but not to date in pigeons. By studying an animal that evolved under significant adaptive pressure to quickly develop a complex and efficient spatial memory system, we may better understand the comparative neurology of neurospatial systems, and plot new and potentially fruitful avenues of comparative research in the future.

Theologies of human nature routinely reflect the insights of evolutionary biology, for which human biological nature is variable, changing and indeterminate in its boundaries with other living things. However, these theologies do not yet reflect what biotechnology discloses about human biological nature, namely, that it is malleable and indeterminate in its boundaries with machines. Does respect for human biological nature as created by God, or protection of the human person whose nature it is, require us to refrain from taking advantage (...) of its malleability and indeterminacy to select or design functions and traits? Or should we welcome malleability and indeterminacy as conditions for us to fulfill a vocation to determine our nature or bring it to perfection? And do malleability and indeterminacy render obsolete the notion that we look to our nature to determine what our good is? This article answers these questions. (shrink)

In replying to Steven Wall’s and Andrew Lister’s thoughtful essays on my account of justificatory liberalism in this issue, I respond to many of their specific criticisms while taking the opportunity to explicate the foundations of justificatory liberalism. Justificatory liberalism takes seriously the moral requirement to justify all claims of authority over others, as well as all coercive interferences with their lives. If we do so, although we are by no means committed to libertarianism, we find that that many of (...) our cherished values, moral intuitions, and political aspirations no longer ground the range of authority over others many of us would claim. In this sense, justificatory liberalism is a theory of limited authority and limited government — which is what a genuinely liberal theory must be. (shrink)
