People frequently gesture when problem-solving, particularly on tasks that require spatial transformation. Gesture often facilitates task performance by interacting with internal mental representations, but how this process works is not well understood. We investigated this question by exploring the case of mental abacus, a technique in which users not only imagine moving beads on an abacus to compute sums, but also produce movements in gestures that accompany the calculations. Because the content of MA is transparent and readily manipulated, the task (...) offers a unique window onto how gestures interface with mental representations. We find that the size and number of MA gestures reflect the length and difficulty of math problems. Also, by selectively interfering with aspects of gesture, we find that participants perform significantly worse on MA under motor interference, but that perceptual feedback is not critical for success on the task. We conclude that premotor processes involved in the planning of gestures are critical to mental representation in MA. (shrink)

Previous work has found that guiding problem-solvers' movements can have an immediate effect on their ability to solve a problem. Here we explore these processes in a learning paradigm. We ask whether guiding a learner's movements can have a delayed effect on learning, setting the stage for change that comes about only after instruction. Children were taught movements that were either relevant or irrelevant to solving mathematical equivalence problems and were told to produce the movements on a series of problems (...) before they received instruction in mathematical equivalence. Children in the relevant movement condition improved after instruction significantly more than children in the irrelevant movement condition, despite the fact that the children showed no improvement in their understanding of mathematical equivalence on a ratings task or on a paper-and-pencil test taken immediately after the movements but before instruction. Movements of the body can thus be used to sow the seeds of conceptual change. But those seeds do not necessarily come to fruition until after the learner has received explicit instruction in the concept, suggesting a “sleeper effect” of gesture on learning. (shrink)

Understanding the relationship between wilderness outings and the resulting experience has been a central theme in resource-based, outdoor recreation research for nearly 50 years. The authors provide a review and synthesis of literature that examines how people, over time, build relationships with wilderness places and express their identities as consequences of multiple, ongoing wilderness engagements (i.e., continued participation). The paper reviews studies of everyday places and those specifically protected for wilderness and backcountry qualities. Beginning with early origins and working through (...) contemporary research the authors synthesize what diverse social scientists have learned about the long-term and continual nature of wilderness participation and its impact on the formation of identity. The thrust of the paper points researchers, planners, and managers in non-traditional directions and reframes goals and objectives for visitor planning and management in wilderness and other protected areas.

The first part of this paper explores the general issues in using Artificial Life techniques to program actual mobile robots. In particular it explores the difficulties inherent in transferring programs evolved in a simulated environment to run on an actual robot. It examines the dual evolution of organism morphology and nervous systems in biology. It proposes techniques to capture some of the search space pruning that dual evolution offers in the domain of robot programming. It explores the relationship between robot (...) morphology and program structure, and techniques for capturing regularities across this mapping. (shrink)

The purpose of this essay is to critically appraise J. Angelo Corlett's recent interpretation of Kant's theory of punishment as well as his rejection of Hegel's penology. In taking Kant to be a retributivist at a primary level and a proponent of deterrence at a secondary level, I believe Corlett has inappropriately wed together Kant's distinction between moral and positive law. Moreover, his support of Kant on these grounds is misguided as it is instead Hegel who holds such a distinction. (...) Finally, I attempt to refute the almost timeless retributivist rejection of deterrence-based theories of punishment on the grounds that the latter somehow would condone in some cases the punishment of innocent persons. These individuals almost always demand that no innocent person be punished as a rule of the highest order. (shrink)

This paper focuses on the structure and substance of the Core Content Framework (CCF), a controversial document which stipulates content that providers of teacher education in England must incorporate in their programmes. We identify both a concept of instrumental trainability and a lack of coherence in the CCF which suggests it is unsuitable as a guide to a curriculum for teacher education. Drawing on Bernstein’s work and its application by other sociologists of educational knowledge, we identify how the CCF embeds (...) a ‘generic mode’ in teacher education that has roots outside of disciplinary structures of knowledge production and therefore foregrounds a type of official pedagogy that sees teaching as a technical performance and leaves gaps in the knowledge and understanding a new teacher requires to make sound educational judgements. Employing Muller’s distinction between conceptual and contextual coherence, we argue that the CCF is based upon an imaginary notion of instructional practice that does not fully grasp the context of teachers’ work. We illustrate the argument via an analysis of the language, structure, and three of the eight sections in the CCF. (shrink)

It is widely accepted by the scientific community and beyond that human beings are primarily responsible for climate change and that climate change has brought with it a number of real problems. These problems include, but are not limited to, greater threats to coastal communities, greater risk of famine, and greater risk that tropical diseases may spread to new territory. In keeping with J. S. Mill's 'Harm Principle', green political theorists often respond that if we are contributing a harm to (...) others in contributing to climate change and its negative effects, we then have a negative duty to assist those we have harmed and to reduce our carbon emissions. In this paper, I will take seriously negative duties stemming from a contribution to climate change and demonstrate that our negative duties do not demand that we necessarily end our contribution to climate change if we were able to compensate those who may be affected by climate change. Thus, the conclusion of many green political theorists - that we must reduce our carbon emissions - does not necessarily follow from the view that humans are primarily responsible for climate change and its attended ill effects.

Plato justifies the concentration and exercise of power for persons endowed with expertise in political governance. This article argues that this justification takes two distinctly different sets of arguments. The first is what I shall call his 'ideal political philosophy' described primarily in the Republic as rule by philosopher-kings wielding absolute authority over their subjects. Their authority stems solely from their comprehension of justice, from which they make political judgements on behalf of their city-state. I call the second set of (...) arguments Plato's 'practical political philosophy' underlying his later thought, where absolute rule by philosopher-kings is undermined by the impure character of all political knowledge. Whereas the complete comprehension of justice sanctions the absolute political power of those with this expertise, partial knowledge of justice disallows for such a large investment of power. Plato's practical political philosophy argues for a mixed theory of governance fusing the institutions of monarchy with democracy in the best practical city-state. Thus, Plato comes to realize the insurmountable difficulties of his ideal political thought, preferring a more practical political philosophy instead. (shrink)

The causal exclusion argument suggests that mental causes are excluded in favour of the underlying physical causes that do all the causal work. Recently, a debate has emerged concerning the possibility of avoiding this conclusion by adopting Woodward's interventionist theory of causation. Both proponents and opponents of the interventionist solution crucially rely on the notion of supervenience when formulating their positions. In this article, we consider the relation between interventionism and supervenience in detail and argue that importing supervenience relations into (...) the interventionist framework is deeply problematic. However, rather than reject interventionist solutions to exclusion wholesale, we wish to propose that the problem lies with the concept of supervenience. This would open the door for a moderate defence of the interventionist solution to the exclusion argument. (shrink)

This paper offers two potential worries in Robert B. Talisse's A Pragmatist Philosophy of Democracy. The first worry is that is that the picture of democracy on offer is incomplete. While Talisse correctly argues that democracy is about more than elections, democracy is also about more than deliberation between citizens. Talisse's deliberative democracy is problematic to the degree its view of deliberation fails to account for democracy. The second worry we may have concerns the relationship between Talisse's Peircean pragmatism and (...) deliberative democracy. If this pragmatism is always open to revision and change in light of future evidence, then no pragmatist should adhere to only one particular political system, such as democracy. When we claim that only one system can ever be justified, then we fail to honour our professed openness to revision and change in the future. If my analysis is correct, then I do not aim to demonstrate that Talisse's Peircean pragmatism is incorrect, only incomplete. Thus, the hope of this paper is to help develop this pragmatism further.

In Physics 4.11, Aristotle says that changes are continuous because magnitude is continuous. I suggest that this is not Aristotle’s considered view, and that in Generation and Corruption 2.10 Aristotle argues that this leads to the unacceptable consequence that alterations can occur discontinuously. Physics 6.4 was written to amend this theory, and to argue that changes are continuous because changing bodies are so. I also discuss the question of Aristotle’s consistency on the possibility of discontinuous alterations, such as freezing.

In this article, I argue that - despite the absence of any clear influence of one theory on the other - the legal theories of Dworkin and Hegel share several similar and, at times, unique positions that join them together within a distinctive school of legal theory, sharing a middle position between natural law and legal positivism. In addition, each theory can help the other in addressing certain internal difficulties. By recognizing both Hegel and Dworkin as proponents of a position (...) lying in between natural law and legal positivist jurisprudence, we can gain clarity in why their general legal theories seem to fit uncomfortably, if indeed they can be said to fit at all, within so many different camps - while fitting comfortably in no particular camp - as well as highlight what has been overlooked.

boundaries. It is impossible to do good science without having an appreciation for the problems and concepts in the other levels of abstraction (at least in the direction from biology towards physics), but there are whole sets of tools, methods of analysis, theories and explanations within each discipline which do not cross those boundaries.

How can we distinguish one mind from another? How are we to determine what unifies the mind? Given radical mental disunity, these questions need to be answered.

Virginia Held's recent How Terrorism Is Wrong offers us any number of important contributions to how we think about terrorist violence. My discussion will focus on only one of these contributions, namely, how terrorism may be justified. This justification rests upon a group being denied a voice. Thus, terrorism may become justified where this demand to be heard is denied, coupled with the corollary that all nonviolent options have been exhausted. I will argue that we should require a more narrow (...) justification of terrorism. This is because I believe Held's understanding may be open to abuses that we should close off. I will begin by looking at how she defines terrorism. I will next turn to how terrorism may be justified on her account before arguing that a more narrow justification is required and what this might look like. (shrink)

Robert B. Talisse's A Pragmatist Philosophy of Democracy is a genuine tour de force. His aim is both to defend a particular view of pragmatism originating with the work of Charles Sanders Peirce and, at the same time, argue in favour of a new view of deliberative democracy developed from Talisse's Peircean pragmatism. The result is a stunning achievement with real persuasive power. In this article, I will focus on one worry, namely, that the picture of democracy on offer is (...) incomplete. While Talisse correctly argues that democracy is about more than elections, democracy is also about more than deliberation between citizens. Talisse's deliberative democracy is problematic to the degree its view of deliberation fails to account for democracy. If my analysis is correct, then I do not aim to demonstrate that Talisse's Peircean pragmatism is incorrect, only incomplete. Thus, the hope of this article is to help develop this pragmatism further. (shrink)

Comparative analysis of Socrates and key figures in Mahayana Buddhism on surprising similarities on epistemology, their relevance for ethics and their divergence.

This is a review of Richard Lippke - "Rethinking Imprisonment".

One of the most controversial aspects of legal philosophy concerns the justification of specific punishments for particular criminal violations. Surprisingly, there has not been any attempt to arrive systematically at any conclusive formula for deriving correct punishments. This article aspires to fulfil this urgent need. I shall examine (1) retributive, (2) consequentialist, (3) reformative, and (4) deterrent punishments in an attempt to derive general equations. It is my wish that by contributing a general formula for each theory we might have (...) a new perspective for comparison. This article finds that the contestability of ascertaining the most appropriate punishment for a criminal is in large part a product of the unstable foundations each penal theory rests on. In addition, almost every variety of penal theories relies on assumptions about criminal culpability, grounded in implicit intentionality. Thus, the contestability of choosing correct punishments to ‘fit’ different crimes is primarily dependent upon the best judgement of judicial officers, not on empirical ‘facts’. (shrink)

Deterrence is a theory which claims that punishment is justified through preventing future crimes, and is one of the oldest and most powerful theories about punishment. This volume brings together the leading work on deterrence from the dominant international figures in the field. Deterrence is examined from various critical perspectives, including its diversity, relation with desert, the relation of deterrence with incapacitation and prevention, the role deterrence has played in debates over the death penalty, and deterrence and corporate crime.

Just War Theory raises some of the most pressing and important philosophical issues of our day. This book brings together some of the most important essays in this area written by leading scholars and offering significant contributions to how we understand just war theory.

In this journal, Michael Clark defends a "A Non-Retributive Kantian Approach to Punishment". I argue that both Kant's and Rawls's theories of punishment are retributivist to some extent. It may then be slightly misleading to say that by following the views of Kant and Rawls, in particular, as Clark does, we can develop a nonretributivist theory of punishment. This matter is further complicated by the fact Clark nowhere addresses Rawls's views on punishment: Rawls endorses a mixed theory combining retributive and (...) utilitarian features. Of those discussed by Clark, only Scanlon defends the use of nonretributivist punishments. Yet, here too Clark nowhere addresses Scanlon's views on punishment. Thus, Clark's views on retributive punishment are highly problematic. (shrink)

British idealism flourished in the late 19th century and early 20th centuries. It was a movement with a lasting influence on the social and political thought of its time in particular. British idealists helped popularize the work of Immanuel Kant and G. W. F. Hegel in the Anglophone world, but they also sought to use insights from the philosophies of Kant and Hegel to help create a new idealism to address the many pressing issues of the Victorian period in Britain (...) and its aftermath. These contributions related to theories of freedom, the common good, political obligation, the state, and punishment. The British idealists also made important contributions in areas other than Hegelian scholarship and ethics, including logic, metaphysics, and the philosophy of religion. The movement declined by the start of World War I. This entry will highlight the most important work by British idealists themselves and by their best interpreters. Thus this entry will be grouped by individuals rather than by theme. (shrink)

Literature and Character Education in Universities presents the potential of literary and philosophical texts for character education in modern universities. The book engages with theoretical and practical aspects of character development in higher education, combining conceptual discussion of the role of literature in character education with applied case studies from university classrooms. Character education within the academic context of the university presents unique challenges and opportunities. Literature and Character Education in Universities presents perspectives from academics in Europe, the USA and (...) Asia, offering unique insights into the ways that engaged reading and discussion of core texts can promote the development of intellectual and moral virtues. Chapters draw on a wide range of texts from Confucius' Analects to J. D. Salinger's The Catcher in the Rye, focusing on themes such as truthfulness, self-knowledge, prudence, tolerance, friendship, and humility. Literature and Character Education in Universities will be of real use to researchers, academics and postgraduates in the fields of higher education, philosophy, and literature. It should be essential reading for university educators interested in character development and advocates of literary education in modern universities. (shrink)

Current Legal Issues, like its sister volume Current Legal Problems, is based upon an annual colloquium held at University College London. Each year, leading scholars from around the world gather to discuss the relationship between law and another discipline of thought. Each colloqium examines how the external discipline is conceived in legal thought and argument, how the law is pictured in that discipline, and analyses points of controversy in the use, and abuse, of extra-legal arguments within legal theory and practice.Law (...) and Psychology, the latest volume in the Current Legal Issues series, contains a broad range of essays by scholars interested in the interactions between law and psychology. The volume includes studies of jury trials in terrorism cases, psychological evidence in family law cases, child witness testimony and the role of psychology in punishment theory. (shrink)

Mahadeviyakka was a radical 12th century Karnataka saint of whom surprisingly little has been written. Considered the most poetic of the Virásaivas, her vacanas are characterized by their desperate searching for iva. I attempt to convey Mahadevi's epistemology and its struggle to 'know' Shiva, necessitating a lifetime of searching for him; offer an interpretation of the innate presence of Shiva in the world and its consequences for epistemology; and explore the sense of tragic love inherent in devotional searching for Shiva. (...) My primary goal is to offer a powerful and positive, yet critical, interpretation of Mahadevi's beautiful prose on her relationship with Shiva. . (shrink)
