The present paper presents a philosophical analysis of earth science, a discipline that has received relatively little attention from philosophers of science. We focus on the question of whether earth science can be reduced to allegedly more fundamental sciences, such as chemistry or physics. In order to answer this question, we investigate the aims and methods of earth science, the laws and theories used by earth scientists, and the nature of earth-scientific explanation. Our analysis leads to the tentative conclusion that (...) there are emergent phenomena in earth science but that these may be reducible to physics. However, earth science does not have irreducible laws, and the theories of earth science are typically hypotheses about unobservable (past) events or generalised - but not universally valid - descriptions of contingent processes. Unlike more fundamental sciences, earth science is characterised by explanatory pluralism: earth scientists employ various forms of narrative explanations in combination with causal explanations. The main reason is that earth-scientific explanations are typically hampered by local underdetermination by the data to such an extent that complete causal explanations are impossible in practice, if not in principle.

In the past 150 years there have been many attempts to draw parallels between cultural and biological evolution. Most of these attempts were flawed due to lack of knowledge and false ideas about evolution. In recent decades these shortcomings have been cleared away, thus triggering a renewed interest in the subject. This paper offers a critical survey of the main issues and arguments in that discussion. The paper starts with an explication of the Darwinian algorithm of evolution. It is argued (...) that this ‘formula’ is substrate-neutral, which means that biological evolution might not be the only Darwinian process. Other dynamic systems could evolve as well provided that certain conditions are met. In the case of human culture this seems to be the case. The paper then focuses on the notion of niche construction. It is argued that niche construction plays a crucial role in human evolution because it has altered the sources of natural selection and thus the path of evolution. Next two approaches to cultural evolution are discussed: sociobiology and memetics. I will argue that both approaches have flaws because they either underestimate the influence of culture or they stretch analogies too far. Finally two common objections against the idea of cultural evolution are addressed: Lamarckian inheritance and the issue of guided variation. I will argue that although cultural evolution differs from biological evolution in several respects, these discrepancies do not jeopardize the claim that cultural evolution is essentially Darwinian.

This article tries to shed light on the mystery of human culture. Human beings are the only extant species with cumulative, evolving cultures. Many animal species do have cultural traditions in the form of socially transmitted practices but they typically lack cumulative culture. Why is that? This discrepancy between humans and animals is even more puzzling if one realizes that culture seems highly advantageous. Thanks to their accumulated knowledge and techniques our early ancestors were able to leave their cradle in (...) Africa and swarm out across the planet, thereby adjusting themselves to a whole range of new environments. Without culture this would have been impossible. So we may ask once again: if cumulative culture is so useful, why don’t other animals have it? In order to explain this mystery I won’t appeal to the major transitions in human evolution—like walking upright, crafting stone tools and controlling fire, etc.—because that would be question begging. Instead I try to unearth the mechanisms that caused those evolutionary turning points to occur in the first place. It seems that unlike other animals, humans are predisposed to efficiently acquire, store and transmit cultural information in such ways that our cultures can genuinely evolve. (shrink)

Discoveries in social psychology pose important questions for philosophical pedagogy. For example, social psychologists have identified several error-producing biases that are commonly impediments to critical thinking. Recent evidence suggests that the most effective way of improving students’ critical thinking is to address these biases explicitly and metacognitively. Biases that produce errors in thinking are not the only psychological features relevant to philosophical pedagogy. Additionally, experimental philosophers have applied the methods of social psychology to uncover various influences on philosophical intuitions. This (...) research may naturally lead an instructor to wonder if research in experimental philosophy ought to change our teaching methods. We argue that the discoveries of experimental philosophy need not change pedagogies that use a Socratic methodology. We provide paradigmatic examples of pedagogical techniques that justify different approaches that include the insights of social psychology and meet generally accepted outcomes for introductory philosophy courses.

This paper responds to the recent situationist critique of practical rationality and decision-making. According to that critique, empirical evidence indicates that our choices are governed by morally irrelevant situational factors and not durable character traits, and rarely result from overt rational deliberation. This critique is taken to indicate that popular moral theories in the Western tradition are descriptively deficient, even if normatively plausible or desirable. But we believe that the situationist findings regarding the sources of, or influences over, our moral (...) agency do not reflect durable features of human nature, and claim that these findings are a byproduct of a deficient approach to moral education. Existing models of moral education, which are “positive” in nature, do a poor job of developing virtuous people. Instead, we argue that a “negative” approach to moral education, traceable to Locke, Smith, and Rousseau, would be more successful. This strategy represents something of a compromise between the strategies adopted by thinkers like Rachana Kamtekar : 458–491 2004), who argues that traditional moral categories escape largely untouched by findings in social psychology, and John Doris :504–530 1998) and Gilbert Harman : 87–94 2003), who argue that findings in psychology prove our traditional moral theories are defective.

For many centuries, philosophers have debated this question: “Does God exist?” Surprisingly, they have paid rather less attention to this distinct – but also very important – question: “Would God’s existence be a good thing?” The latter is an axiological question about the difference in value that God’s existence would make (or does make) in the actual world. Perhaps the most natural position to take, whether or not one believes in God, is to hold that it would be a very (...) good thing if such a being were to exist. After all, God is traditionally thought to be perfectly powerful and good, and it might seem obvious that such a being’s existence would make things better than they would otherwise be. But this judgment has been contested: some philosophers have held that God’s existence would make things worse, and that, on this basis, one can reasonably prefer God’s non-existence. We first distinguish a wide array of axiological positions concerning the value of God’s existence which might be held by theists, atheists, and agnostics alike. We next construe these positions as comparative judgments about the axiological status of various possible worlds. We then criticize an important recent attempt to show that God’s existence would make things worse, in various ways, than they would otherwise be. (shrink)

Can an assessment of individuals’ narcissism help explain the quality of a respondent’s ethical judgment? How is the relationship between religiosity and ethical judgment moderated by the effects of narcissism? With a sample of 385 undergraduate business majors, this study uses a taxonomic approach to examine the effects of intrinsic and extrinsic religiosity as well as orthodox Christian beliefs on ethical judgment. Three distinct clusters were identified: Skeptics, Nominals, and Devouts. Surprisingly, of the three clusters, Nominals and Devouts were the (...) only groups impacted by narcissism, although Skeptics overall demonstrate the worst ethical judgment. (shrink)

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Although Occupy Wall Street may no longer appear in news headlines, the international movement provides a rich curriculum on space and protest that are worthy of contemplation in social studies classrooms and research. This paper looks historically at how location and free speech became linked and informed one another during the 20th century in the US. It then looks critically at three sites of Occupy in the US that reflect the contested public representations of occupation. The investigation of these critical (...) incidents enables a discussion of how Occupy expands prior discussion of the linkage between space and protest while indicating how political, economic, and technological shifts change this relationship in the 21st century.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

The health of newborns has always been subject to the natural lottery. When in the past a severely disabled baby was born, nature provided the “solution,” and the child did not survive. Medical technology has brought about a change; fetuses who would have died during pregnancy or newborns who once would have had little chance to survive are now kept alive. Although these technological advances do benefit many children, the dark side is that more severely handicapped babies are surviving.When a (...) severely disabled baby is born, all persons concerned are faced with emotional difficulties as well as moral and legal dilemmas. Questions that arise include whether it is acceptable, morally and legally, to allow the severely handicapped newborn to die by forgoing treatment or by direct intervention. (shrink)

A sample of 523 newly ordained female Anglican clergy in England, Ireland, Scotland and Wales completed the Eysenck Personality Profiler. The data demonstrated that the female clergy tended to be less extravert than women in general, less neurotic than women in general, and less toughminded than women in general. These findings help to clarify the way in which women clergy tend to project a characteristically masculine personality profile in respect of one major dimension of personality, but a characteristically feminine personality (...) profile in respect of the other two major dimensions of personality.

This article presents preliminary considerations and results from a research project designed to investigate the relation between gestures, graphic traces and perceptions. More specifically, the project aims to test the hypothesis that graphic traces, including handwriting, can set up graphetic empathy between writers and readers of traces across long temporal and spatial distances. Insofar as a graphic trace is lawfully related to the gesture by which it came into being, the trace itself will hold information about the gesture, which may (...) resonate with the sensorimotor system of a perceiver, as if they themselves performed the gesture. If this is in fact so, it will have important and hitherto unanticipated implications for our understanding of the embodiment of reading. As part of the article we will present and discuss the results of a neurophenomenological trial study through which we attempt to operationalize the gesture-trace and trace–perception relations respectively.

PurposeTo explore the mindfulness practice, its long-term effects, facilitators and barriers, in clinical clerkship students 2 years after participation in an 8-week mindfulness-based stress reduction training.MethodA qualitative study was performed by semi-structured in-depth interviews with 16 clinical clerkship students selected by purposive sampling. Students had participated in a MBSR training 2 years before and were asked about their current mindfulness practice, and the long-term effects of the MBSR training. Thematic analysis was conducted using the constant comparison method. Data saturation was (...) reached after 16 interviews.ResultsMost interviewees were still engaged in regular, predominantly informal, mindfulness practice, although some discontinued mindfulness practice and reported an “unchanged lifestyle.” Three main themes came forward; “focused attention and open awareness” during daily activities as core elements of long-term mindfulness practice; “changes in behavior and coping” that resulted from taking a pause, reflecting, recognizing automatic behavioral patterns and making space for a conscious response; “integration in personal and professional life” by enhanced enjoyment of daily activities, improved work-life-balance and making different career choices. Barriers and facilitators in starting and maintaining mindfulness practice were understanding and intention as “pre-conditions”; practical, personal, and professional factors of students in maintaining practice.ConclusionTwo years after participation in a MBSR training, many interviewees were still engaged in mindfulness practice contributing to both personal and professional changes. In light of the high clerkship demands, MBSR training could be a valuable addition to medical curricula, supporting medical students in developing necessary competencies to become well-balanced professionals.

In this essay I present an overview of the problem of climate change, with attention to issues of interest to feminists, such as the differential responsibilities of nations and the disproportionate “vulnerabilities” of females, people of color, and the economically disadvantaged in relation to climate change. I agree with others that justice requires governments, corporations, and individuals to take full responsibility for histories of pollution, and for present and future greenhouse gas emissions. Nonetheless I worry that an overemphasis on household (...) and personal-sphere fossil fuel emissions distracts from attention to higher-level corporate and governmental responsibilities for addressing the problem of climate change. I argue that more attention should be placed on the higher-level responsibilities of corporations and governments, and I discuss how individuals might more effectively take responsibility for addressing global climate change, especially when corporations and governments refuse to do so.

Small businesses in developing countries, as part of global supply chains, are sometimes assumed to respond in a straightforward manner to institutional demands for improved working conditions. This article problematizes this perspective. Drawing upon extensive qualitative data from Tirupur’s knitwear export industry in India, we highlight owner-managers’ agency in avoiding or circumventing these demands. The small businesses here actively engage in irresponsible business practices and “evasion” institutional work to disrupt institutional demands in three ways: undermining assumptions and values, dissociating consequences, (...) and accumulating autonomy and political strength. This “evasion” work is supported by three conditions: void, distance, and contradictions. Through detailed empirical findings, the article contributes to research on both small business social responsibility and institutional work. (shrink)

The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and link approaches, and review the relevant empirical evidence. We conclude that learning is the consequence of propositional reasoning processes that cooperate with the unconscious processes involved (...) in memory retrieval and perception. We argue that this new conceptual framework allows many of the important recent advances in associative learning research to be retained, but recast in a model that provides a firmer foundation for both immediate application and future research.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.2 (2002) 1-11 [Access article in PDF] On Ecofeminist Philosophy Chris Cuomo In the heat of a historical moment when the interwoven nature of imperialism, ecological degradation, exploitation of workers, racism, and women's oppression is painfully obvious to many, ecofeminism appears to be gaining in popularity. As Karen Warren's book Ecofeminist Philosophy (2000) illustrates, a key insight of ecological feminism is captured by the (...) phrase "it's all connected." In more precise terms, ecofeminism stresses the depth to which human realities are embedded in ecological realities, and the fact that we are all composed of physical and conceptual connections and relationships. Ecofeminists also make strong normative claims about those connections, and they find present ecological and social relationships to be far more morally troubling than "we" modern thinkers tend to acknowledge.Karen Warren's work has been incredibly influential in the development of ecofeminism, especially as a philosophical perspective. In her 1987 essay "Feminism and Ecology: Making Connections," she argued for a basic ecofeminist position: that feminists ought to pay attention to environmental issues and ecological interdependencies, and that environmentalists ought to attend to the connections among ecological degradation, sexism, and other forms of social oppression. A wealth of ecofeminist poetry, fiction, and political writing had been published in the seventies and early eighties, before "Feminism and Ecology" appeared on the pages of [End Page 1] the journal Environmental Ethics. But Karen Warren was the among the first to use the tools of analytic philosophy to articulate and argue for ecofeminism as a philosophical position, ethical approach, and political movement.In fact, Mary Daly's Gyn/Ecology: The Metaethics of Radical Feminism (1978) was arguably the first work in contemporary academic philosophy to engage ecofeminism (my first acquaintance with ecofeminist theory was made through a special issue of the feminist magazine Heresies, on feminism and ecology). But Daly's emphasis was on the plight of females in patriarchal social environments. Karen Warren and Australian philosopher Val Plumwood brought full focus to the eco in ecofeminism, applying feminist philosophy (and especially feminist ethics) to our relations with the more than human world, and in turn articulating a broader theory of oppression and liberation. Their analytic approaches resulted in philosophy that synthesizes as it clarifies, taking seriously the value of nature, the history of philosophy, the power of culture, and the insights of good science.In Ecofeminist Philosophy Karen Warren presents ecofeminism as a general school of thought, though she also argues for a particular set of ecofeminist principles, values, methodologies, and practices. In terms of both her method and her conclusions, it is important to note that her emphasis on clearly articulated principles is by no means a defense of an absolutist or falsely universalizing ethic. Rather, Warren's ecofeminist philosophy emerges from her reading of a wide and diverse array of theoretical and political examples. Like Noël Sturgeon's Ecofeminist Natures: Race, Gender, Feminist Theory and Political Action (1997), which focuses on feminist ecological movements, Warren's project is to look for and describe the family resemblances among diverse examples of ecofeminism. This approach allows her to articulate epistemic, moral, and political positions that are pluralist, yet do not avoid making bold truth-claims. For example, Warren argues that "something is a feminist issue if an understanding of it helps one understand the oppression, subordination, or domination of women" (Warren 2000, 1).In a sense such a definition is wide open, taking various approaches and issues to be worthy of feminist attention. At the same time, it certainly does not allow just any perspective to count as feminist. Throughout Ecofeminist Philosophy, Warren defends multicultural ethics while clearly advocating specific transcultural values, such as justice and caring: [End Page 2] If we dare to care, if we dare to enter into community with others through an honest recognition of our commonalities and differences, we will be poised to create generally respectful, nonviolent, care-based, intentional communities where commonalities and differences are just that... Such intentional communities are a creative alternative to violence-prone communities where order is imposed from outside through unjustified... (shrink)

In this research, the use of narrative accounts is investigated as the catalyst for the evolution of one coach's identity. Unable to sustain a coaching identity that was deemed to be appropriate by my coaching mentors, I disengaged from the swimming culture. This was due in part to the expression of power within the mentor–mentee relationship embedded in the coach development pathway, as well as within the wider sporting culture. By utilizing a narrative approach; writing and deconstructing my own narratives (...) in relation to coach identity development within the mentor–mentee relationship, I developed an alternative approach. I established a sustainable coaching identity that demonstrated evidence-based judgement and reflective consideration of actions rather than the obtuse reproduction of mentor coach practice. This research suggests that the use of narrative as an integral element in coach education can be powerful in terms of deconstructing cultural ideologies and in the construction of a sustainable coaching identity. The combination of these two components is powerful in terms of enabling a coaching identity to evolve. It is therefore suggested that the development of a sustainable mentor–mentee relationship is inextricably linked with the expression of narrative and the critical reflection on the same. (shrink)

Written in an engaging narrative style these philosophical investigations undermine racist hierarchies along with false natualistic conceptions of the meanings of race and universalistic understandings of gender, by considering whiteness as it shapes and is infused by gender, class, sexuality, and culture. Central to this project are questions about how it is that culture and the state create such a wide range of different people who understand themselves as white. The essays collected here discuss how one learns to be a (...) good white Southern woman, what it means to pass as white, and whether there really is a dilemma that accompanies white privilege.

In this paper we consider the concept of a self-aware agent. In cognitive science agents are seen as embodied and interactively situated in worlds. We analyse the meanings attached to these terms in cognitive science and robotics, proposing a set of conditions for situatedness and embodiment, and examine the claim that internal representational schemas are largely unnecessary for intelligent behaviour in animats. We maintain that current situated and embodied animats cannot be ascribed even minimal self-awareness, and offer a six point (...) definition of embeddedness, constituting minimal conditions for the evolution of a sense of self. This leads to further analysis of the nature of embodiment and situatedness, and a consideration of whether virtual animats in virtual worlds could count as situated and embodied. We propose that self-aware agents must possess complex structures of self-directed goals; multi-modal sensory systems and a rich repertoire of interactions with their worlds. Finally, we argue that embedded agents will possess or evolve local co-ordinate systems, or points of view, relative to their current positions in space and time, and have a capacity to develop an egocentric space. None of these capabilities are possible without powerful internal representational capacities. (shrink)

We investigate the question “To what extent can random reals be used as a tool to establish number theoretic facts?” Let $\text{2-\textit{RAN\/}}$ be the principle that for every real $X$ there is a real $R$ which is 2-random relative to $X$. In Section 2, we observe that the arguments of Csima and Mileti [3] can be implemented in the base theory $\text{\textit{RCA}}_0$ and so $\text{\textit{RCA}}_0+\text{2-\textit{RAN\/}}$ implies the Rainbow Ramsey Theorem. In Section 3, we show that the Rainbow Ramsey Theorem is (...) not conservative over $\text{\textit{RCA}}_0$ for arithmetic sentences. Thus, from the Csima—Mileti fact that the existence of random reals has infinitary-combinatorial consequences we can conclude that $\text{2-\textit{RAN\/}}$ has non-trivial arithmetic consequences. In Section 4, we show that $\text{2-\textit{RAN\/}}$ is conservative over $\text{\textit{RCA}}_0+\text{\textit{B\/}$\,\Sigma$}_2$ for $\Pi^1_1$-sentences. Thus, the set of first-order consequences of $\text{2-\textit{RAN\/}}$ is strictly stronger than $P^-+I\Sigma_1$ and no stronger than $P^-+\text{\textit{B\/}$\,\Sigma$}_2$. (shrink)
