A point charge accelerating under the influence of an external force emits electromagnetic radiation that reduces the increase in its mechanical energy. This causes a reduction in the particle's acceleration. We derive the decrease in acceleration due to radiation reaction for a particle accelerating parallel to its velocity, and show that it has a negligible effect.

Let me begin with a quote: “The universal organum of philosophy—the ground stone of its entire architecture—is the philosophy of art.”1 This statement, made in 1800 by the German Idealist philosopher Friedrich Schelling, is rather striking, not only because of its grandiosity, but also because it contrasts with what the majority of contemporary philosophers would be prepared to say on the subject. There is nevertheless a grain of truth in the claim that there is a peculiar connection between art and (...) philosophy and in the claim that aesthetics is a central area of philosophy. First of all, it is worth noting that, even if the philosophy of art has not played a role in the systems of all the indisputably great philosophers, or even of most of them, it has occupied an important place in the thought of quite a few, among them Plato, Aristotle, Hume, Kant, Schopenhauer, Nietzsche, Hegel and Sartre. And a good number of philosophers of lesser rank—including Croce, Collingwood, Dewey, Bergson, Santayana, Gadamer and, evidently, Schelling, also had a philosophy of art; one finds them perhaps more interested in it than in, say, ethics. Why this natural, even if not inevitable, link between philosophy and art? (shrink)

The meaning of Lorentz contraction in special relativity and its connection with Bell’s spaceships parable is discussed. The motion of Bell’s spaceships is then compared with the accelerated motion of a rigid body. We have tried to write this in a simple form that could be used to correct students’ misconceptions due to conflicting earlier treatments.

We study the acceleration and collisions of rigid bodies in special relativity. After a brief historical review, we give a physical definition of the term ‘rigid body’ in relativistic straight line motion. We show that the definition of ‘rigid body’ in relativity differs from the usual classical definition, so there is no difficulty in dealing with rigid bodies in relativistic motion. We then describe The motion of a rigid body undergoing constant acceleration to a given velocity.The acceleration of a rigid (...) body due to an applied impulse.Collisions between rigid bodies.

La créativité est une valeur aujourd’hui abondamment conférée à des objets fort divers. Ainsi, bien qu’elle soit principalement discutée dans le domaine de l’art, on en parle souvent à propos des sciences, du sport, de l’entrepreneuriat, de la politique, de la pédagogie ou encore de situations plus ordinaires, telles que la créativité culinaire ou humoristique. En quoi ces diverses formes de créativité se ressemblent-elles ? Qu’est-ce qui fait leur valeur et en quoi se distinguent-elles de proches parentes comme l’originalité, l’inventivité (...) ou l’intelligence ? (shrink)

In this paper we argue that there is a large class of expressions, typified by ‘plastic flower’, ‘stuffed animal’ and ‘kosher bacon’, that have a unique semantics combining compositional, idiomatic and decompositional interpretation. These expressions are compositional because their constituents contribute their meanings to the meanings of the wholes; they are idiomatic because their interpretation involves assigning dictionary entries to non-terminal elements in their syntactic structure; and they are decompositional because their meanings have proper parts that are not the meanings (...) of any of their syntactic constituents. We argue that extensionalist semantics, on which the meaning of an expression is a function from domains to extensions in those domains, cannot provide an adequate account of the semantics of these expressions, and that supplementation with a theory of pragmatic interpretation does not improve the situation. We show how our account explains the intensionality and the productivity of these expressions. (shrink)

First published in 1990, _Existentialism_ is widely regarded as a classic introductory survey of the topic, and has helped to renew interest in existentialist philosophy. The author places existentialism within the great traditions of philosophy, and argues that it deserves as much attention from analytic philosophers as it has always received on the continent.

The chapter challenges hyperbolic claims about the centrality of appreciation of beauty to Buddhism. Within the texts, attitudes are more mixed, except for a form of 'inner beauty' - the beauty found in the expression of virtues or wisdom in forms of bodily comportment. Inner beauty is a stable presence throughout Buddhist history, practices, and art.

The Planteome project provides a suite of reference and species-specific ontologies for plants and annotations to genes and phenotypes. Ontologies serve as common standards for semantic integration of a large and growing corpus of plant genomics, phenomics and genetics data. The reference ontologies include the Plant Ontology, Plant Trait Ontology, and the Plant Experimental Conditions Ontology developed by the Planteome project, along with the Gene Ontology, Chemical Entities of Biological Interest, Phenotype and Attribute Ontology, and others. The project also provides (...) access to species-specific Crop Ontologies developed by various plant breeding and research communities from around the world. We provide integrated data on plant traits, phenotypes, and gene function and expression from 95 plant taxa, annotated with reference ontology terms. (shrink)

The Plant Ontology (PO; http://www.plantontology.org/) is a publicly-available, collaborative effort to develop and maintain a controlled, structured vocabulary (“ontology”) of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and stages of plant development, using the data model adopted by the Gene Ontology. From its original design covering only rice, maize and Arabidopsis, the scope of the PO has been expanded (...) to include all green plants. The PO was the first multi-species anatomy ontology developed for the annotation of genes and phenotypes. Also, to our knowledge, it was one of the first biological ontologies that provides translations (via synonyms) in non-English languages such as Japanese and Spanish. There are about 2.2 million annotations linking PO terms to over 110,000 unique data objects representing genes or gene models, proteins, RNAs, germplasm and Quantitative Traits Loci (QTLs) from 22 plant species. In this paper, we focus on the plant anatomical entity branch of the PO, describing the organizing principles, resources available to users, and examples of how the PO is integrated into other plant genomics databases and web portals. We also provide two examples of comparative analyses, demonstrating how the ontology structure and PO-annotated data can be used to discover the patterns of expression of the LEAFY (LFY) and terpene synthase (TPS) gene homologs.

This paper examines how a person’s life may be shaped by living with a sense of the mystery of reality. What virtues, if any, are encouraged by such a sense? The first section rehearses a radical ”doctrine of mystery’, according to which reality as it anyway is, independently of human perspectives, is ineffable. It is then argued that a sense of mystery may provide ”measure’ for human lives. For it is possible for a life to be ”consonant’ with this sense (...) -- through exercising humility, for example -- and even to emulate mystery. A further section corrects a misunderstanding about the connection between a sense of mystery and the virtues it invites, while a final section considers the relationship between living with mystery and religious faith.

In this paper, I explore a prominent question of Hericlitean scholarship: how is change possible? Karl Popper and G. S. Kirk tackle this same question. Kirk asserts that Heraclitus believed that change is present on a macrocosmic level and that all change is regulated by the cosmic principle logos. Popper, on the other hand, claims Heraclitus believed that change is microcosmic and rejected that all change is regulated by logos. I argue for a combination of aspects from each of their (...) claims and conclude that change is present both microcosmically and macrocosmically and that all change is governed by logos . (shrink)

Reasoning about analogical arguments is known to be subject to a variety of cognitive biases, and a lack of clarity about which factors can be considered strengths or weaknesses of an analogical argument. This can make it difficult both to design empirical experiments to study how people reason about analogical arguments, and to develop scalable tutoring tools for teaching how to reason and analyze analogical arguments. To address these concerns, we describe WG-A (Warrant Game — Analogy), a framework for people (...) to analyze analogical arguments based on Bartha’s (2010) Articulation Model of analogical argumentation. We carry out two experiments designed to probe WG-A’s effectiveness in improving participants’ ability to reason about analogical arguments and argumentation in general, and argue that WG-A is a promising approach, though it is in need of further development.

Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the Semantic Web. This paper provides background on what bio-ontologies are, why they are relevant to botany, and the principles of ontology development. It includes an overview of ontologies and related resources that are relevant to plant science, (...) with a detailed description of the Plant Ontology (PO). We discuss the challenges of building an ontology that covers all green plants (Viridiplantae). Key results: Ontologies can advance plant science in four keys areas: 1. comparative genetics, genomics, phenomics, and development, 2. taxonomy and systematics, 3. semantic applications and 4. education. Conclusions: Bio-ontologies offer a flexible framework for comparative plant biology, based on common botanical understanding. As genomic and phenomic data become available for more species, we anticipate that the annotation of data with ontology terms will become less centralized, while at the same time, the need for cross-species queries will become more common, causing more researchers in plant science to turn to ontologies.

There is a global shortage of organs for transplantation and despite many governments making significant changes to their organ donation systems, there are not enough kidneys available to meet the demand. This has led scientists and clinicians to explore alternative means of meeting this organ shortfall. One of the alternatives to human organ transplantation is xenotransplantation, which is the transplantation of organs, tissues, or cells between different species. The resurgence of interest in xenotransplantation and recent scientific breakthroughs suggest that genetically-engineered (...) pigs may soon present a realistic alternative as sources of kidneys for clinical transplantation. It is therefore important for nurses and allied health professionals to understand what is involved in xenotransplantation and its future implications for their clinical practices. First, we explore the insufficiency of different organ donation systems to meet the kidney shortage. Second, we provide a background and a summary of the progress made so far in xenotransplantation research. Third, we discuss some of the scientific, technological, ethical, and economic issues associated with xenotransplantation. Finally, we summarise the literature on the attitudes of healthcare professionals toward xenotransplantation. (shrink)

Communicating interdisciplinary information is difficult, even when two fields are ostensibly discussing the same topic. In this work, I’ll discuss the capacity for analogical reasoning to provide a framework for developing novel judgments utilizing similarities in separate domains. I argue that analogies are best modeled after Paul Bartha’s By Parallel Reasoning, and that they can be used to create a Toulmin-style warrant that expresses a generalization. I argue that these comparisons provide insights into interdisciplinary research. In order to demonstrate this (...) concept, I will demonstrate that fruitful comparisons can be made between Buddhism and Artificial Intelligence research. (shrink)

The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies. This paper describes the structure of the ontology and the design principles we used in constructing PO terms for plant development stages. It also provides details of the methodology and rationale behind our revision and expansion of the PO to cover development stages for all plants, particularly (...) the land plants (bryophytes through angiosperms). As a case study to illustrate the general approach, we examine variation in gene expression across embryo development stages in Arabidopsis and maize, demonstrating how the PO can be used to compare patterns of expression across stages and in developmentally different species. Although many genes appear to be active throughout embryo development, we identified a small set of uniquely expressed genes for each stage of embryo development and also between the two species. Evaluating the different sets of genes expressed during embryo development in Arabidopsis or maize may inform future studies of the divergent developmental pathways observed in monocotyledonous versus dicotyledonous species. The PO and its annotation databasemake plant data for any species more discoverable and accessible through common formats, thus providing support for applications in plant pathology, image analysis, and comparative development and evolution.

Iris Murdoch was a philosopher and novelist who wrote extensively on the themes of love, goodness, religion, and morality. In this article, we explore her notion of ‘moral vision’; the idea that morality is not just about how we act and make choices, but how we see the world in a much broader sense.

This paper walks through four different approaches to Hegel's notion of Consciousness in the Phenomenology of Spirit. Through taking four different approaches our aim is to explore the multifaceted nature of the phenomenological movement of consciousness. The first part provides an overview of the three chapters of the section on Consciousness, namely Sense-Certainty, Perception and Force and the Understanding, attempting to unearth the implicit logic that undergirds Consciousness’ experience. The second part focuses specifically on the shape of Sense-Certainty, providing an (...) analysis of the movement from Sense-Certainty to Perception from a neuroscientific view. Thirdly, we consider an inferentialist reading of the chapters on Consciousness which has been made popular by Robert Brandom. We think that while this view elucidates the connection that Hegel draws between meaning and use, it fails to account for the vital place of immediacy in each of the shapes. Finally, the fourth part suggests that Hegel’s notion of Consciousness improves the reading of tragedy he develops in chapters 5 and 7 of the Phenomenology. While many critics have noted that Hegel fails to do justice to tragic experience, Consciousness contains an epistemology that develops analogously to the heroes of ancient tragedy. Each approach in this paper comes at Hegel’s description of the journey of Consciousness from a different angle, and together they paint a multi-layered picture of a highly important part of Hegel’s corpus.

The Plant Ontology (PO) (http://www.plantontology.org) (Jaiswal et al., 2005; Avraham et al., 2008) was designed to facilitate cross-database querying and to foster consistent use of plant-specific terminology in annotation. As new data are generated from the ever-expanding list of plant genome projects, the need for a consistent, cross-taxon vocabulary has grown. To meet this need, the PO is being expanded to represent all plants. This is the first ontology designed to encompass anatomical structures as well as growth and developmental stages (...) across such a broad taxonomic range. While other ontologies such as the Gene Ontology (GO) (The Gene Ontology Consortium, 2010) or Cell Type Ontology (CL) (Bard et al., 2005) cover all living organisms, they are confined to structures at the cellular level and below. The diversity of growth forms and life histories within plants presents a challenge, but also provides unique opportunities to study developmental and evolutionary homology across organisms.

Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across many key fields in biology, including genomics, systems biology, development, medicine, evolution, ecology, and systematics. Here we survey the current phenomics landscape, including data resources and handling, and the progress that (...) has been made to accurately capture relevant data descriptions for phenotypes. We present an example of the kind of integration across domains that computable phenotypes would enable, and we call upon the broader biology community, publishers, and relevant funding agencies to support efforts to surmount today's data barriers and facilitate analytical reproducibility.

In her recent paper ‘The Epistemology of Propaganda’ Rachel McKinnon discusses what she refers to as ‘TERF propaganda’. We take issue with three points in her paper. The first is her rejection of the claim that ‘TERF’ is a misogynistic slur. The second is the examples she presents as commitments of so-called ‘TERFs’, in order to establish that radical (and gender critical) feminists rely on a flawed ideology. The third is her claim that standpoint epistemology can be used to establish (...) that such feminists are wrong to worry about a threat of male violence in relation to trans women. In Section 1 we argue that ‘TERF’ is not a merely descriptive term; that to the extent that McKinnon offers considerations in support of the claim that ‘TERF’ is not a slur, these considerations fail; and that ‘TERF’ is a slur according to several prominent accounts in the contemporary literature. In Section 2, we argue that McKinnon misrepresents the position of gender critical feminists, and in doing so fails to establish the claim that the ideology behind these positions is flawed. In Section 3 we argue that McKinnon’s criticism of Stanley fails, and one implication of this is that those she characterizes as ‘positively privileged’ cannot rely on the standpoint-relative knowledge of those she characterizes as ‘negatively privileged’. We also emphasize in this section McKinnon’s failure to understand and account for multiple axes of oppression, of which the cis/trans axis is only one. (shrink)

Formal clinical trials of pig-to-human organ transplant—known as xenotransplantation—may begin this decade, with the first trials likely to consist of either adult renal transplants or pediatric cardiac transplant patients. Xenotransplantation as a systematic scientific study only reaches back to the latter half of the 20th century, with episodic xenotransplantation events occurring prior to that. As the science of xenotransplantation has progressed in the 20th and 21st centuries, the public's knowledge of the potential therapy has also increased. With this, there have (...) been shifting ethical stances toward xenotransplantation in key areas, such as religious and public viewpoints towards xenotransplantation, animal rights, and public health concerns. This review provides a historical–ethical account of xenotransplantation and details if or how viewpoints have shifted over time. (shrink)

In the last decade Open Science principles, such as Open Access, study preregistration, use of preprints, making available data and code, and open peer review, have been successfully advocated for and are being slowly adopted in many different research communities. In response to the COVID-19 pandemic many publishers and researchers have sped up their adoption of some of these Open Science practices, sometimes embracing them fully and sometimes partially or in a sub-optimal manner. In this article, we express concerns about (...) the violation of some of the Open Science principles and its potential impact on the quality of research output. We provide evidence of the misuses of these principles at different stages of the scientific process. We call for a wider adoption of Open Science practices in the hope that this work will encourage a broader endorsement of Open Science principles and serve as a reminder that science should always be a rigorous process, reliable and transparent, especially in the context of a pandemic where research findings are being translated into practice even more rapidly.

Jerrold J. Katz often explained his semantic theory by way of an analogy with physical atomism and an attendant analogy with chemistry. In this chapter, I track the origin and uses of these analogies by Katz, both in explaining and defending his decompositional semantic theory, through the various phases of his work throughout his career.

This article articulates our everyday notion of cooperation. First, I topple an orthodoxy of shared agency theory by arguing that shared intentions to J are neither necessary nor sufficient for J to be cooperative. I refute the necessity claim by providing examples of shared intention-free cooperation (in institutional contexts and beyond). I refute the sufficiency claim by observing that coercion and exploitation need not preclude shared intentions but do preclude cooperation. These arguments, in turn, lead to my positive proposal. People (...) cooperate, I argue, just in case their activities are coordinated in ways that do not undermine any participant’s agency. (shrink)

Cooperation has been analyzed primarily in the context of theories of collective intentionality. These discussions have primarily focused on interactions between pairs or small groups of agents who know one another personally. Cooperative game theory has also been used to argue for a form of cooperation in large unorganized groups. Here I consider a form of minimal cooperation that can arise among members of potentially large organized groups (e.g., corporate teams, committees, governmental bodies). I argue that members of organized groups (...) can be minimally cooperative in virtue of playing roles in an organizational structure and having a common goal. The minimal form of cooperation I argue for is not grounded in collective intentions involving symmetric mental states, special collective intentional modes, or joint commitments. More generally, I show how considering minimal cooperation in the context of organized groups provides an opportunity to reevaluate the extent to which the social world and social phenomena depend on internalist mental factors (e.g., intentions, beliefs) and externalist non-mental factors (e.g., documents, laws, job descriptions). The view of minimal cooperation among members of organized groups I offer provides support for an externalist rather than internalist theory of at least one social phenomenon. (shrink)

The conflict between religion and science reached its peak after the Enlightenment. People today exhibit a greater inclination towards science as compared to religion. Religion's influence in shaping human progress diminished as science gained favor. Following over a half-century of strained ties, a movement arose that opposed the growing hostility between religion and science. Today, the era of digital disruption has become part of human civilization. As a result of scientific progress, information technology requires reconciliation with faith. After all, religion (...) needs secular methods and ideas for its advancement. So, this paper offers a new type of entanglement between religion and technology based on cooperative rationality. Cooperative rationality considers reason as the foundation, then cooperation as the next step. Because religion and technology both rely on human reason, with cooperative rationality, religion and technology can find complex, coordinated actions that allow both to benefit. So, organized scientific inquiry is not merely for taking on intellectual tasks but also for humanity. Cooperative rationality relies on fundamental intellectual concerns to pay more attention to technological goals, considering scientific and human values. (shrink)

Dubreuil (Biol Phil 25:53–73, 2010b , this journal) argues that modern-like cognitive abilities for inhibitory control and goal maintenance most likely evolved in Homo heidelbergensis , much before the evolution of oft-cited modern traits, such as symbolism and art. Dubreuil’s argument proceeds in two steps. First, he identifies two behavioral traits that are supposed to be indicative of the presence of a capacity for inhibition and goal maintenance: cooperative feeding and cooperative breeding. Next, he tries to show that these behavioral (...) traits most likely emerged in Homo heidelbergensis . In this paper, I show that neither of these steps are warranted in light of current scientific evidence, and thus, that the evolutionary background of human executive functions, such as inhibition and goal maintenance, remains obscure. Nonetheless, I suggest that cooperative breeding might mark a crucial step in the evolution of our species: its early emergence in Homo erectus might have favored a social intelligence that was required to get modernity really off the ground in Homo sapiens.

The human faculty of moral judgment is not well suited to address problems, like climate change, that are global in scope and remote in time. Advocates of ‘moral bioenhancement’ have proposed that we should investigate the use of medical technologies to make human beings more trusting and altruistic, and hence more willing to cooperate in efforts to mitigate the impacts of climate change. We survey recent accounts of the proximate and ultimate causes of human cooperation in order to assess the (...) prospects for bioenhancement. We identify a number of issues that are likely to be significant obstacles to effective bioenhancement, as well as areas for future research. (shrink)

We present a theory of cooperative-competitive intelligence (CCI), its measures, research program, and applications that stem from it. Within the framework of this theory, satisficing sub-optimal behavior is any behavior that does not promote a decrease in the prospective control of the functional action diversity/unpredictability (D/U) potential of the agent or team. This potential is defined as the entropy measure in multiple, context-dependent dimensions. We define the satisficing interval of behaviors as CCI. In order to manifest itself at individual or (...) team level, this capacity harnesses properties such as degeneracy, pleiotropy (pluri-potentiality), synergies, and metastability. Intelligence is embodied because intelligent behavior is deeply dependent on body functionalities, defined as entropy measures. We base our theory on three principles: (a) relativity of functional entropy/ information in agent (team)-environment systems, (b) tendency toward the satisficing level of D/U potential, and (c) tendency toward the non-decreasing D/U potential. The conjunction of these three principles provides existence of sub-optimal behaviors associated with CCI. First, we deal with the problem of how to reduce multidimensional behavior to a concept that accounts for the vast set of scenarios in which CCI is manifested. Secondly, we define and discuss the three interacting principles that underpin CCI behavior as well as providing an outline for a future CCI research program supported by agent￾based modeling and empirical research. Finally, we provide some preliminary practical issues that stem from the theory. (shrink)

Cooperation admits of degrees. When factory workers stage a slowdown, they do not cease to cooperate with management in the production of goods altogether, but they are not fully cooperative either. Full cooperation implies that participants in a joint action are committed to rendering appropriate contributions as needed toward their joint end so as to bring it about, consistently with the type of action and the generally agreed upon constraints within which they work, as efficiently as they can, where their (...) contributions are sensitive to information (where available) about how others are contributing in the sense that they adjust as needed their contributions in light of information about how others are contributing to ensure effective pursuit of their joint end, where this includes rendering aid to other participants if needed, insofar as they are able. Full cooperation entails those cooperating are engaged in a joint intentional action. Some prominent studies of joint intentional action focus exclusively on cases of full cooperation (notably that of Michael Bratman (2014)). But not all joint intentional action is fully cooperative. One example is the work slowdown. Another example is provided by competitive games like chess and football, or sports like boxing and wrestling, where participants are clearly not intending to contribute to the pursuit of all of the goals of the others engaged in the activity, even when those goals are internal to the type of activity in question, but instead intend actively to frustrate some of them. In this paper, I provide a taxonomy of forms of non-cooperative behavior within the context of behavior that is still to some degree cooperative, and I argue that the minimal conditions of joint intentional action define minimal cooperative behavior, that is, that minimally joint intentional action is per se minimally cooperative behavior. I define in precise terms what that comes to, and how it is possible in cases in which it seems that one or more participants are in one or more ways acting so as to frustrate the contributions of other participants to their joint action.

Effective ethics teaching and training must cultivate both the critical thinking skills and the character traits needed to deliberate effectively about ethical issues in personal and professional life. After highlighting some cognitive and motivational obstacles that stand in the way of this task, the article draws on educational research and the author's experience to demonstrate how cooperative learning techniques can be used to overcome them.

Rules serve many important functions in society. One such function is to codify, and make public and enforceable, a society's desired prescriptions and proscriptions. This codification means that rules come with predefined punishments administered by third parties. We argue that when we look at how third parties punish rule violations, we see that rules and their punishments often serve dual functions. They support and help to maintain cooperation as it is usually theorized, but they also facilitate the domination of marginalized (...) others. We begin by reviewing literature on rules and third-party punishment, arguing that a great deal of punishment research has neglected to consider the unique power of codified rules. We also argue that by focusing on codified rules, it becomes clear that the enforcement of such rules via third-party punishment is often used to exert control, punish retributively, and oppress outgroup members. By challenging idealized theory of rules as facilitators of social harmony, we highlight their role in satisfying personal punishment motives, and facilitating discrimination in a way that is uniquely justifiable to those who enforce them.

We present a multi-agent system where agents can cooperate to solve a system of dependent tasks, with agents having the capability to explore a solution space, make inferences, as well as query for information under a limited budget. Re-exploration of the solution space takes place by an agent when an older solution expires and is thus able to adapt to dynamic changes in the environment. We investigate the effects of task dependencies, with highly-dependent graph G_40 (a well-known program graph that (...) contains 40 highly interlinked nodes, each representing a task) and less-dependent graphs G_18 (a program graph that contains 18 tasks with fewer links), increasing the speed of the agents and the complexity of the problem space and the query budgets available to agents. Specifically, we evaluate trade-offs between the agent's speed and query budget. During the experiments, we observed that increasing the speed of a single agent improves the system performance to a certain point only, and increasing the number of faster agents may not improve the system performance due to task dependencies. Favoring faster agents during budget allocation enhances the system performance, in line with the "Matthew effect." We also observe that allocating more budget to a faster agent gives better performance for a less-dependent system, but increasing the number of faster agents gives a better performance for a highly-dependent system.

According to pluralistic intuitionist theories, some of our moral beliefs are non-inferentially justified, and these beliefs come in both an a priori and an a posteriori variety. In this paper I present new support for this pluralistic form of intuitionism by examining the deeply social nature of moral inquiry. This is something that intuitionists have tended to neglect. It does play an important role in an intuitionist theory offered by Bengson, Cuneo, and Shafer-Landau (forth), but whilst they invoke the social (...) nature of moral inquiry in order to argue that ordinary moral intuitions are trustworthy, my argument focuses on what I will call the ‘frontiers’ of moral inquiry. I will show that inclusive and cooperative dialogue is necessary at moral inquiry’s frontiers, and that intuitionists can expect such dialogue to result in both a priori and a posteriori moral beliefs.

Games have a complex, and seemingly paradoxical structure: they are both competitive and cooperative, and the competitive element is required for the cooperative element to work out. They are mechanisms for transforming competition into cooperation. Several contemporary philosophers of sport have located the primary mechanism of conversion in the mental attitudes of the players. I argue that these views cannot capture the phenomenological complexity of game-play, nor the difficulty and moral complexity of achieving cooperation through game-play. In this paper, I (...) present a different account of the relationship between competition and cooperation. My view is a distributed view of the conversion: success depends on a large number of features. First, the players must achieve the right motivational state: playing for the sake of the struggle, rather than to win. Second, successful transformation depends on a large number of extra-mental features, including good game design, and social and institutional features. (shrink)

Because contractarians see justice as mutual advantage, they hold that justice can be rationally grounded only when each can expect to gain from it. John Rawls seems to avoid this feature of contractarianism by fashioning the parties to the contract as Kantian agents whose personhood grounds their claims to justice. But Rawls also endorses the Humean idea that justice applies only if people are equal in ability. It would seem to follow from this idea that dependent persons (such as the (...) disabled) lack claims of justice. It appears, then, that the Kantian and Humean themes in Rawls conflict. I present a reading of Rawls that resolves this tension between the Kantian and Humean themes. The first theme, I argue, allows Rawls to maintain that persons as such are owed justice regardless of their ability to engage in social cooperation. The second theme, I argue, allows him to retain Hume's connection between justice and reciprocity, but confines the reciprocity condition to relations among nondependents. I conclude that Rawls's approach permits him to rebut recent criticisms leveled by disability theorists and others who claim that his theory excludes dependents. (shrink)

In an earlier paper, I argued for an account of the metaphysics of grace which was libertarian in nature but also non-Pelagian. My goal in the present paper is to broaden my focus on how the human and divine wills relate in graced activities. While there is widespread agreement in Christian theology that the two do interact in an important way, what’s less clear is how the wills of two agents can be united in one of them performing a particular (...) action via a kind of joint or unitive willing. Insofar as the goal in these unitive willings is to have the human will and the divine will operating together in the human bringing about a particular action, I refer to this kind of volition as ”cooperative agency’. I explore two different models -- an identificationist model and an incarnation model -- regarding how the human agent is aligned with God in cooperative agency. I then argue that there are significant reasons for preferring the incarnational model over the identificationist model. (shrink)

Ethological theories usually attribute semantic content to animal signals. To account for this fact, many biologists and philosophers appeal to some version of teleosemantics. However, this picture has recently came under attack: while mainstream teleosemantics assumes that representational systems must cooperate, some biologists and philosophers argue that in certain cases signaling can evolve within systems lacking common interest. In this paper I defend the standard view from this objection.

Fitouchi et al. claim that seemingly victimless pleasures and nonproductive activities are moralized because they alter self-control. Their account predicts that: (1) victimless excesses are negatively moralized because they diminish self-control, and (2) restrained behaviors are positively moralized because they enhance self-control. Several examples run contrary to these predictions and call into question the general relationship between self-control and cooperation.

According to Steven Pinker and his associates the cooperative model of human communication fails, because evolutionary biology teaches us that most social relationships, including talk-exchange, involve combinations of cooperation and conflict. In particular, the phenomenon of the strategic speaker who uses indirect speech in order to be able to deny what he meant by a speech act (deniability of conversational implicatures) challenges the model. In reply I point out that interlocutors can aim at understanding each other (cooperation), while being in (...) conflict. Furthermore, Pinker’s strategic speaker relies on the Cooperative Principle when conveying a conversational implicature, and so non-cooperative behaviour (denial) only emerges as a response to a negative reaction from the audience. It is also doubtful in the cases Pinker presents whether a denial will successfully cancel the conversational implicature –change the audience’s interpretation of speaker’s meaning. I also argue that a strategic speaker might choose indirect speech due to the ignorability of conversational implicatures, in which case the strategic speaker can be highly cooperative. (shrink)

Philosothons are events in which students practise Community of Philosophical Inquiry, usually with awards being made using three criteria: critical thinking, creative thinking and collaboration. This seems to generate a tension. On the one hand it recognises collaboration as a valued trait; on the other hand, the element of competition may seem antithetical to collaboration. There are various possible considerations relevant to this apparent problem. We can pose them as seven questions. One, do the awards really recognise the best performers? (...) Two, do the students and teachers see the awards as fair and reasonable? Three, do the awards recognise cooperation as a valuable contribution? Four, do Philosothons generate enthusiasm and goodwill? Five, might awards motivate students to try harder to do well? Six, if competition is normal in society, does it follow that it is justified as part of the Philosothon? Seven, do awards have a role in bringing the event to a climax? In this article, we will develop and evaluate the arguments suggested by these questions. Our conclusion is that the competitive element in the Philosothon is not antithetical to the collaborative ideal of philosophy. (shrink)

The study sought to investigate the effects of using cooperative learning on female teacher trainees of the Colleges of Education in learning some selected topics in Integrated Science. The investigation also sought to determine whether the Cooperative Learning Approach enhances the attitude and motivation of the trainees towards learning of Integrated Science. The study was carried out at the St. Monica’s College of Education in the Mampong Municipality of the Ashanti Region. In all, 80 teacher trainees consisting of 40 each (...) from control and experimental groups were purposively sampled to participate in the study. The teacher trainees in the experimental group were exposed to the Cooperative Learning Approach and the trainees in the control group were lectured during the period of the study. The results of the study showed that the cooperative learning strategy was very relevant and beneficial in helping the teacher trainees of the St. Monica’s College of Education to improve on their performance in, and attitudes towards, the teaching and learning of Integrated Science. It was therefore recommended among other things that the science teachers should endeavour to integrate cooperative learning into their routine methods of instruction in the teaching and learning of Integrated Science.

Most of the contributions to Cooperation and Its Evolution grapple with the distinctive challenges presented by the project of explaining human sociality. Many of these puzzles have a ‘chicken and egg’ character: our virtually unparalleled capacity for large-scale cooperation is the product of psychological, behavioural, and demographic changes in our recent evolutionary history, and these changes are linked by complex patterns of reciprocal dependence. There is much we do not yet understand about the timing of these changes, and about the (...) order in which different aspects of human social psychology (co-)evolved. In this review essay, I discuss four such puzzles the volume raises. These concern punishment and norm-psychology, moral judgement and the moral emotions, hierarchy and top-down coercion, and property rights and legal systems. (shrink)

Review of Cooperation and its Evolution, edited by Kim Sterelny, Richard Joyce, Brett Calcott, and Ben Fraser.

Rawlsian justice as fairness is neither fundamentally luck egalitarian nor relational egalitarian. Rather, the most fundamental idea is that of society as a fair system of cooperation. Collective pensions provide a case study which illustrates the fruitfulness of conceiving justice in these latter terms. Those who have recently reached the age of majority do not now know how long they will live in retirement or how well any investments they try to save up for their retirement would fare. From the (...) perspective of the beginning of their working lives, it is therefore rational for each to enter into an agreement with others, who also do not yet know their fates, that, if one turns out to be among the unfortunate whose private pension pots would not have yielded enough for one’s retirement, one will receive much more in retirement, whereas those whose pension pots would have overflowed their retirements will receive somewhat less. These terms are to each person’s expected advantage, which is made possible by a fair sharing of the fruits of social cooperation which arise through the efficiencies reaped by the pooling of the risk of outliving what one could save for one’s retirement on one’s own. It is rational for each to agree to share one another’s fates by pooling risks across both space and time, on fair terms of social cooperation for mutual advantage. Even when collective pensions arise from, and are proportional to, a baseline of unequal income, they can be defended on grounds of reciprocity involving regard for one another as equals. (shrink)

I discuss what learned and innate routines of self and other attribution agents need to possess if they are to enter into cooperative arrangements as described game theoretically. I conclude that these are not so different from belief desire psychology as described by philosophers of mind.

Philosophical accounts of joint action are often prefaced by the observation that there are two different senses in which several agents can intentionally perform an action Φ, such as go for a walk or capture the prey. The agents might intentionally Φ together, as a collective, or they might intentionally Φ in parallel, where Φ is distributively assigned to the agents, considered as a set of individuals. The accounts are supposed to characterise what is distinctive about activities in which several (...) agents intentionally Φ collectively rather than distributively. This dualism between joint and parallel action also crops up outside philosophy. For instance, it has been imported into a debate about whether or not group hunting among chimpanzees is a form of joint cooperative hunting. I offer an account of a form of joint action that falls short of what most philosophers take to be required for genuine joint action, but which is not merely parallel activity. This shows that the dualism between the genuinely joint and the merely parallel is false. I offer my account as an explication of an influential definition of “cooperative behaviour” given by the primatologists Christophe and Hedwig Boesch. (shrink)
