We highlight connections between accessible categories and abstract elementary classes , and provide a dictionary for translating properties and results between the two contexts. We also illustrate a few applications of purely category-theoretic methods to the study of AECs, with model-theoretically novel results. In particular, the category-theoretic approach yields two surprising consequences: a structure theorem for categorical AECs, and a partial stability spectrum for weakly tame AECs.

We introduce a family of rank functions and related notions of total transcendence for Galois types in abstract elementary classes. We focus, in particular, on abstract elementary classes satisfying the condition known as tameness, where the connections between stability and total transcendence are most evident. As a byproduct, we obtain a partial upward stability transfer result for tame abstract elementary classes stable in a cardinal $\lambda$ satisfying $\lambda^{\aleph_{0}}\gt \lambda$, a substantial generalization of a result of Baldwin, Kueker, and VanDieren.

We provide comprehensive, level-by-level characterizations of large cardinals, in the range from weakly compact to strongly compact, by closure properties of powerful images of accessible functors. In the process, we show that these properties are also equivalent to various forms of tameness for abstract elementary classes. This systematizes and extends results of [W. Boney and S. Unger, Large cardinal axioms from tameness in AECs, Proc. Amer. Math. Soc.145(10) (2017) 4517–4532; A. Brooke-Taylor and J. Rosický, Accessible images revisited, Proc.

_Metaphysics: A Contemporary Introduction_ is for students who have already completed an introductory philosophy course and need a fresh look at the central topics in the core subject of metaphysics. It is essential reading for any student of the subject. This Fourth Edition is revised and updated and includes two new chapters on Parts and Wholes, and Metaphysical Indeterminacy or vagueness. This new edition also keeps the user-friendly format, the chapter overviews summarizing the main topics, concrete examples to clarify difficult (...) concepts, annotated further reading at the end of each chapter, endnotes, and a full bibliography. Topics addressed include: the problem of universals the nature of abstract entities the problem of individuation the nature of modality identity through time the nature of time the nature of parts and wholes the problem of metaphysical indeterminacy the Realism/anti-Realism debate. Wherever possible, Michael J. Loux and Thomas M. Crisp relate contemporary views to their classical sources in the history of philosophy. As experienced teachers of philosophy and important contributors to recent debates, Loux and Crisp are uniquely qualified to write this book. (shrink)

Four studies tested the hypothesis that a weaker belief in free will would be related to feeling less gratitude. In Studies 1a and 1b, a trait measure of free will belief was positively correlated with a measure of dispositional gratitude. In Study 2, participants whose free will belief was weakened (vs. unchanged or bolstered) reported feeling less grateful for events in their past. Study 3 used a laboratory induction of gratitude. Participants with an experimentally reduced (vs. increased) belief in free (...) will reported feeling less grateful for the favor. In Study 4, a reduced (vs. increased) belief in free will led to less gratitude in a hypothetical favor scenario. This effect was serially mediated by perceiving the benefactor as having less free will and therefore as being less sincerely motivated. These findings suggest that belief in free will is an important part of being able to feel gratitude. (shrink)

Research into the work of UK estate agents reveals a love‐hate attitude on the part of the public and profound ethical ambivalences. Dr Clarke is a member of the Department of Sociology, Social Policy and Social Work Studies, The University of Liverpool, POB 147, Liverpool L69 3BX. This article draws on his study Slippery Customers: Estate Agents, The Public and Regulation, Blackstone Press 1994, co‐authored with D. Smith and M. McConville.

This article argues that the moral right to be discharged only for good cause and like rights can be contracted away by employees in appropriate circumstances. It maintains that the rights in question are not inalienable, and that there is nothing irrational about an employee''s wishing to deal them away. It also maintains that inequalities in bargaining power between employers and employees are insufficiently pervasive to justify a flat ban on the alienation of these rights. For a waiver of such (...) rights to be valid, however, employees must have full knowledge of its terms.The question addressed here bears on several legal and policy issues affecting termination of the employment relation. If employees can contract away their right to a goodcause discharge, the American doctrine of employment at willmight find justification in the face of that right. In addition, the alienability of such discharge rights may be necessary to justify express disclaimers of wrongful discharge liability and the waiver provision of the new U.S. Draft Uniform Employment-Termination Act.

The fitting-attitudes analysis of value, which states that something's being good consists in its being the fitting object of some pro-attitude, has recently been the focus of intense debate. Many objections have been levelled against this analysis. One objection to it concerns the ‘challenge from partiality’, according to which it can be fitting to display partiality toward objects of equal value. Several responses to the challenge have been proposed. This paper criticizes these and other responses and then offers a response (...) that, it is claimed, solves the challenge. (shrink)

Long‐range correlation is a general class of coordination pattern found to be common to the intrinsic dynamics of complex systems, including human behavior. Balasubramaniam, Hove, and Médé investigate intrinsic dynamics in repeated finger movements, and they find that different measures of movement dynamics yield different long‐range correlations. Results shed light on the way that coordination patterns are expressed as a function of measurement context.

Jeffery et al. suggest that three-dimensional environments are not represented according to their volumetric properties, but in a quasi-planar fashion. Here we take into consideration the role of visual experience and the use of technology for spatial learning to better understand the nature of the preference of horizontal over vertical spatial representation.

The Paleolithic paintings and drawings found on cave walls at sites in France and Spain, such as Lascaux, Altamira and Vallon-Pont-D'Arc, have profound effects on those who see them. In addition to their historical interest, they are prized for their aesthetic and spiritual qualities, which have had an important influence on modern art. But the caves are small and the paintings are fragile. Access to them has been sharply limited: some caves have been closed to protect the paintings from the (...) damage caused by human respiration; access to others is limited to those who negotiate a daunting reservation scheme. Despite being the heritage of humanity as a whole, the cave paintings are, and must be, restricted to a very few. Not everyone who wants to see the paintings can do so if they are to survive.

Leibniz's philosophy of time, often seen as a precursor to current forms of relationalism and causal theories of time, has rightly earned the admiration of his more recent counterparts in the philosophy of science. In this article, I examine Leibniz's philosophy of time from a new perspective: the role that tense and non-tensed temporal properties/relations play in it. Specifically, I argue that Leibniz's philosophy of time is best (and non-anachronistically) construed as a non-tensed theory of time, one that dispenses with (...) tensed temporal properties such as past, present, and future. In arguing for this thesis, I focus on the three facets of Leibniz's philosophy most relevant for evaluating his commitment to a B-theory of time: (1) the nature of change, (2) the reality of the future, and (3) the truth-conditions for tensed temporal statements. Despite prima facie evidence to the contrary, I show that a close examination of Leibniz's views on these topics provides compelling evidence for interpreting his philosophy of time as a B-theory of time.

The paper examines some of the many factors that influence the shape of designed products in the mechanical engineering industries. It is shown that, once the detailed shape of a product has been determined, the analysis of that shape from the viewpoints of various engineering activities downstream of design leads to a range of inherently different perceptions of it.

We do things in time. Philosophy of action can capture this phenomenon in at least two ways. On one hand, it might focus on the way that temporal preferences and long-term temporal horizons affect the rationality of decisions in the present (see, e.g., Parfit 1984; Rawls 1971). Such work may focus on the way we discount the distant future, for example, or prioritize the future over the past. Approaches of this kind treat time as, in a sense, something external to (...) agency; it sets various constraints on what we may rationally intend, for example. But if temporal considerations can constrain agency, it follows that they can also structure it internally, and if they can do so, it seems likely that this is possible because agency is already temporally structured. This volume focuses on the way that agency is temporally structured from within, such that time is an ineliminable constituent of agency. (shrink)

Preston and Hofelich (2012) suggested that researchers disagree on the role of self–other overlap in empathy due to a failure to differentiate among neural overlap, subjective resonance, and personal distress; they also developed a framework for tying neural and subjective overlap to various aspects of functioning they include in the construct of empathy. Although we found their discussion of different processes that have been labeled empathy interesting and helpful, we found their discussion of self–other overlap to be somewhat less useful (...) for conceptualizing differences among empathy-related processes. In addition, we provide an alternative perspective to their reasoning regarding the role of experience and neural overlap in an aspect of empathy-related responding (e.g., concern or compassion).

Visual information can be provided to blind users through sensory substitution devices that convert images into sound. Through extensive use to develop expertise, some blind users have reported visual experiences when using such a device. These blind expert users have also reported visual phenomenology to other sounds even when not using the device. The blind users acquired synthetic synaesthesia, with visual experience evoked by sounds only after gaining such expertise. Sensorimotor learning may facilitate and perhaps even be required to develop (...) expertise in the use of multimodal information. Furthermore, other areas where expertise is acquired in dividing attention amongst cross-modal information or integrating such information might also give rise to synthetic synaesthesia. (shrink)

Many writers accept the following thesis about responsibility: (R) For one to be responsible for something is for one to be such that it is fitting that one be the object of some reactive attitude with respect to that thing. This thesis bears a striking resemblance to a thesis about value that is also accepted by many writers: (V) For something to be good (or neutral, or bad) is for it to be such that it is fitting that it be (...) the object of some pro-attitude (or indifference, or some contra-attitude). V has been the subject of intense debate in recent years, in part because of its incorporation into what has come to be called the “buck-passing” account of value. In particular, V is open to three challenges: that it is not necessarily the case that whatever is good is the fitting object of a pro-attitude; that it is not necessarily the case that whatever is the fitting object of a pro-attitude is good; and that, even if there is a strict equivalence between what is good and what is the fitting object of a pro-attitude, still the former is not to be analyzed in terms of the latter. The resemblance between V and R has not been previously commented on, but, once it is recognized, it is clear that R is open to challenges that resemble those to which V is vulnerable. This paper explores both the challenges to V and the parallel challenges to R and discusses responses that may be given to these challenges. The interrelation between V and R is then examined, and a general lesson is drawn concerning how to adjudicate disputes about the nature of moral responsibility. (shrink)

To date, insufficient work has been carried out on how children view living organisms in the environment. In this study a large number of conversations were audio-taped and transcribed while primary age pupils observed meal worms or brine shrimps (both of which are invertebrates) during science activities. Analysis revealed the ways in which the pupils interpreted what they saw in terms of their prior experience. We discuss the implications of these and others of our findings for school education and the (...) development of children's ethical constructions of their environments. (shrink)

This thought-provoking book initiates a dialogue among scholars in rhetoric and hermeneutics in many areas of the humanities. Twenty leading thinkers explore the ways these two powerful disciplines inform each other and influence a wide variety of intellectual fields. Walter Jost and Michael J. Hyde organize pivotal topics in rhetoric and hermeneutics with originality and coherence, dividing their book into four sections: Locating the Disciplines; Inventions and Applications; Arguments and Narratives; and Civic Discourse and Critical Theory. Contributors to this (...) volume include Hans-Georg Gadamer, Paul Ricoeur, Gerald L. Bruns, Charles Altieri, Richard E. Palmer, Calvin O. Schrag,.Victoria Kahn, Eugene Garver, Michael Leff, Nancy S. Streuver, Wendy Olmsted, David Tracy, Donald G. Marshall, Allen Scult, Rita Copeland, William Rehg, and Steven Mailloux. For readers across the humanities, the book demonstrates the usefulness of rhetorical and hermeneutic approaches in literary, philosophical, legal, religious, and political thinking. With its stimulating new perspectives on the revival and interrelation of both rhetoric and hermeneutics, this collection is sure to serve as a benchmark for years to come. (shrink)

We use formal semantic analysis based on new constructions to study abstract realizability, introduced by Läuchli in 1970, and expose its algebraic content. We claim realizability so conceived generates semantics-based intuitive confidence that the Heyting Calculus is an appropriate system of deduction for constructive reasoning.Well-known semantic formalisms have been defined by Kripke and Beth, but these have no formal concepts corresponding to constructions, and shed little intuitive light on the meanings of formulae. In particular, the completeness proofs for these semantics (...) do not generate confidence in the sufficiency of the Heyting Calculus, since we have no reason to believe that every intuitively constructive truth is valid in the formal semantics.Läuchli has proved completeness for a realizability semantics with formal concepts analogous to constructions. We argue in some detail that, in spite of a certain inherent inexactness of the analogy, every intuitively constructive truth is valid in Läuchli semantics, and therefore the Heyting Calculus is powerful enough to prove all constructive truths. Our argument is based on the postulate that a uniformly constructible object must be communicable in spite of imprecision in our language, and that the permutations in Läuchli's semantics represent conceivable imprecision in a language, while allowing a certain amount of freedom in choosing the particular structure of the language.We give a detailed generalization of Läuchli's proof of completeness for the propositional part of the Heyting Calculus, in order to make explicit constructive and algebraic content.In our treatment, we establish several new results about Läuchli models. We show how to extend the sconing and gluing constructions familiar from Kripke and Frame semantics and Topos theory, to Läuchli models, and use them to give an algebraic approach to countermodel construction. In particular, the Läuchli arguments are given without the restriction to the integers, Z, as a group of permutations, which makes much of the coding scheme used in Läuchli's original paper transparent.We also make use of a new propositions-as-types syntax for the Heyting calculus, with limited nondeterminism, in which validity of formulae can be decided without loop-detection.

It has recently been argued that the principle that "ought" implies "can" entails the principle that moral responsibility requires alternate possibilities, and hence that the acceptance of the former principle requires acceptance of the latter. This paper disputes the alleged entailment and gives reasons for accepting the former principle while rejecting the latter.

Background: Studies of sexual conditioning typically focus on the development of conditioned responses to a stimulus that precedes and has become associated with a sexual unconditioned stimulus (US). Such a sexually conditioned stimulus (CS) provides the opportunity for feed-forward regulation of sexual behavior, which improves the efficiency and effectiveness of the sexual activity. Objective and Design: The present experiments were conducted to provide evidence of such feed-forward regulation of sexual behavior in laboratory studies with domesticated quail by measuring how many (...) fertilized eggs were produced by the female after the sexual encounter. During the conditioning phase, male and female quail received a conditioned stimulus paired with the opportunity to copulate with each other. Results: Sexual conditioning increased the number of eggs that were fertilized as a consequence of copulation, especially if both the male and the female were exposed to the sexual CS. This conditioned fertility effect occurred with a range of CS durations and CS types. The conditioned fertility effect also occurred in situations involving sexual competition. When two males copulated with the same female, DNA fingerprinting showed that the male whose sexual encounter was signaled by a sexual CS was responsible for most of the resulting offspring. Sexual conditioning also reduced the first-male disadvantage in fertilization that occurs when two males copulate with the same female separated by several hours. Another significant finding was that sexual conditioning attenuated the usual drop in fertilization rate that occurs when the same male copulates with two females in succession. Conclusion: These results show that sexual conditioning increases the number of offspring that are produced in both isolated male-female encounters and in situations that involve two males copulating with the same female or one male copulating with more than one female. By increasing fertilization rates, sexual conditioning can alter genetic transmission across generations and shape evolutionary change.

_Asking Good Questions_ moves beyond a traditional discussion of ethical theory, focusing on how educators can use these important frameworks to facilitate critical thinking about real-life ethical dilemmas. In this way, authors Nancy Stanlick and Michael Strawser offer students a theoretical tool kit for creatively addressing issues that influence their own environments. This text begins with a discussion of key ethical theorists and then guides the reader through a series of original case studies and follow-up activities that facilitate critical (...) thinking, emphasize asking thought provoking questions, and teach the student to address the complexity of ethical dilemmas while incorporating the viewpoints of their peers. Additionally, Stanlick and Strawser include an extensive preface, a mind-mapping technique for analyzing and formulating arguments, and a six step process for approaching complex real-life moral issues. Each chapter incorporates suggested assignments, discussion questions, and references for further reading, and a guide for instructors offering a sample course schedule and suggestions on how to use this book effectively is also available. This text is designed to help educators engage students in a meaningful discussion of how historical theories apply to their own lives, providing rich and unique resources to learn about these critical issues.

For nearly two centuries, developmental biologists have known that body organs are derived from distinct germ layers. They have argued that adult stem cells formed in one of these, mesoderm for example, cannot give rise to cells that originate in another. We disagree. An exception to this “rule” has been described in crayfish recently. In this species, hemocytes appear to replenish neurogenic cells. This may happen in humans as well. In women who were given male bone marrow‐derived cells, Y chromosome (...) positive cheek cells and brain neurons were detected. While repopulation of these tissues by bone marrow derived cells may not occur normally, and while it does not appear to be terribly efficient, the phenomenon should be studied in more detail. Perhaps cells in the marrow could be used to regenerate tissues elsewhere. (shrink)

The migration and settlement of 11 million unauthorized immigrants is among the leading political challenges facing the United States today. The majority of unauthorized immigrants in the U.S. have been here for more than five years, and are settling into American communities, working, forming families, and serving in the military, even though they may be detained and deported if they are discovered. An open question remains as to what to do about unauthorized immigrants who are already living in the United (...) States. On one hand it is important that the government sends a message that future violations of immigration law will not be tolerated. On the other sits a deeper ethical dilemma that is the focus of this book: what do the state and citizens owe to unauthorized immigrants who have served their adopted country? -/- Earned Citizenship argues that long-term unauthorized immigrant residents should be able to earn legalization and a pathway to citizenship through service in their adopted communities. Their service would act as restitution for immigration law violations. Military service in particular would merit naturalization in countries with a strong citizen-soldier tradition, including the United States. The book also considers the civic value of caregiving as a service to citizens and the country, contending that family immigration policies should be expanded to recognize the importance of caregiving duties for dependents. This argument is part of a broader project in political theory and public policy aimed at reconciling civic republicanism with a feminist ethic of care, and its emphasis on dependency work. As a whole, Earned Citizenship provides a non-humanitarian justification for legalizing unauthorized immigrants based on their contributions to citizens and institutions in their adopted nation.

In this chapter, I argue that nursing ethics is rightfully viewed as a distinct field of critical inquiry relevant to the nursing profession and its purposes. While there are areas of overlap and mutual interests with bioethics, medical ethics, and the ethics of other disciplines, nursing ethics is concerned with the particular purposes and perspectives of the profession and problems faced in trying to achieve its goals. Nursing ethics, as a field of inquiry, has to do with the purposes of (...) the profession, the scope and limits of practice, expectations of nurse clinicians, educators and scholars, and the future direction of disciplinary knowledge development. Nursing ethics, like other professional ethics, is informed by insights from centuries of moral philosophizing, the conceptualization of nurse scholars and researchers about the distinct nature of the profession, and the experiences of frontline nurses. It is an applied, professional ethics. (shrink)

The aim of this collection is to create a curated set of key German source texts from the eighteenth-century life sciences devoted to theories of generation, heredity, and race. The criteria for inclusion stem from our sense that there is an argument to be made for connecting three domains of inquiry that have heretofore remained mostly distinct in both their presentation and scholarly analysis: i) life science debates regarding generation and embryogenesis, ii) emerging philosophical and anthropological theories regarding the nature (...) of racial typology, and iii) the role of empire in supplying the ethnographic materials in use as evidence for the various investigations and theories being proposed. The Key Texts volume thus has three sections. The first section is devoted to selections from theorists working to create an account of the processes guiding generation and embryogenetic development. Given that at the time there were few ways to definitively prove that babies received contributions from both parents in their creation, mixed-race children became increasingly valuable sources of evidence for those insisting on joint inheritance. Although this sets up the second section of the volume—since one can trace a clear facet of racial biometric science out of this original set of enquiries—the bulk of section two is devoted to the many different accounts created at the time to understand and delineate racial differences. The third section is focused on ‘race and empire’ in order to situate the scientific texts of the previous sections in their socio-historical context. By including these pieces, it is our aim to remind readers that scientific curiosity over the nature and origin of racial diversity did not develop in a vacuum but indeed existed in full knowledge of the exploitation and dispossession of human beings. The ‘materials’ for this research program were in many cases either directly taken from black and brown human beings caught up in Europe’s colonial projects or were provided by the data gathered during large-scale voyages of exploration. The material basis of this type of research was rarely reflected upon by any of the theorists in sections one and two of the volume, a fact that has led many historians of science to focus on these theories without attention to the socio-historical context; we are deliberately trying to avoid this and indeed to deepen our own readers’ appreciation of the fact.

In this paper, I discuss the role of Anselm’s ontological argument in the philosophy of R.G. Collingwood. Anselm’s argument appears prominently in Collingwood’s Essay on Philosophical Method (1933) and Essay on Metaphysics (1940), as well as in his early work Speculum Mentis (1924). In the proof, Collingwood finds the central expression of the priority of “faith” in the first principles of thought to reason’s activities. For Collingwood, it is Anselm’s proof that clearly expresses this relationship between faith and reason. The (...) two elements of this analysis that must be understood if one is to understand Collingwood’s use of the proof are what he means by “the idea of an object that shall completely satisfy the demands of reason” and the “special case of metaphysical thinking.” I analyze both of these elements and conclude by showing how Anselm’s proof is essential to Collingwood’s historical science of mind.
