An intriguing development in the realm of commercial software has arisen over the last decade, from highly improbable beginnings. From its inception in the ‘hacker ethic’, freeware has had a huge impact on IT businesses around the world, most strongly in the guise of its spin‐off, open source software. The eventual consequences are that, for example, more than 60% of all the servers on the World Wide Web are running the Apache open source system, and Linux, the open source cousin (...) of Unix, is challenging Microsoft’s products as the most popular business server operating system. Major IT users such as multinational banks, and major IT companies including IBM, Hewlett Packard, Sun Microsystems, Dell, Oracle, Informix, Intel, Fujitsu, AMD and Computer Associates are investing in and supporting Linux. In 1998, Netscape Communications made public the source code for its Netscape web browser. In 1999 Apple published the source for the ‘Darwin’ core of its Mac OS X. The Perl freeware programming language continues to gain popularity for web‐based applications. (shrink)

For the last four decades much of the world’s most advanced technical resources have been devoted to military systems; but with the end of the Cold War economic and technical resources are being freed to yield the so‐called ‘peace dividend’. This promotes the possibility of a more ethical orientation to many information technologists’ work, and also represents the chance to argue for, and develop, more socially useful and responsible applications of computer technology, in accordance with the development of professional ideals (...) and standards within the computing industry.

In this paper I explore the nature of confabulatory explanations of action guided by implicit bias. I claim that such explanations can have significant epistemic benefits in spite of their obvious epistemic costs, and that such benefits are not otherwise obtainable by the subject at the time at which the explanation is offered. I start by outlining the kinds of cases I have in mind, before characterising the phenomenon of confabulation by focusing on a few common features. Then I introduce (...) the notion of epistemic innocence to capture the epistemic status of those cognitions which have both obvious epistemic faults and some significant epistemic benefit. A cognition is epistemically innocent if it delivers some epistemic benefit to the subject which would not be attainable otherwise because alternative (less epistemically faulty) cognitions that could deliver the same benefit are unavailable to the subject at that time. I ask whether confabulatory explanations of actions guided by implicit bias have epistemic benefits and whether there are genuine alternatives to forming a confabulatory explanation in the circumstances in which subjects confabulate. On the basis of my analysis of confabulatory explanations of actions guided by implicit bias, I argue that such explanations have the potential for epistemic innocence. I conclude that epistemic evaluation of confabulatory explanations of action guided by implicit bias ought to tell a richer story, one which takes into account the context in which the explanation occurs.

Predictive processing has begun to offer new insights into the nature of conscious experience—but the link is not straightforward. A wide variety of systems may be described as predictive machines, raising the question: what differentiates those for which it makes sense to talk about conscious experience? One possible answer lies in the involvement of a higher-order form of prediction error, termed expected free energy. In this paper we explore under what conditions the minimization of this new quantity might underpin conscious (...) experience. Our suggestion is that the minimisation of Expected Free Energy is not in itself sufficient for the occurrence of conscious experience. Instead, it is relevant only insofar as it helps deliver what Ward et al. ( 2011 ) have previously described as a _sense of our own poise over an action space_. Perceptual experience, we will argue, is nothing other than the process that puts current actions in contact with goals and intentions, enabling some creatures to know the space of options that their current situation makes available. This proposal fits with recent work suggesting a deep link between conscious contents and contents computed at an ‘intermediate’ level of processing, apt for controlling action. (shrink)

Sensory substitution devices are a type of sensory prosthesis that (typically) convert visual stimuli transduced by a camera into tactile or auditory stimulation. They are designed to be used by people with impaired vision so that they can recover some of the functions normally subserved by vision. In this chapter we will consider what philosophers might learn about the nature of the senses from the neuroscience of sensory substitution. We will show how sensory substitution devices work by exploiting the cross-modal (...) plasticity of sensory cortex: the ability of sensory cortex to pick up some types of information about the external environment irrespective of the nature of the sensory inputs it is processing. We explore the implications of cross-modal plasticity for theories of the senses that attempt to make distinctions between the senses on the basis of neurobiology. (shrink)

The U.S. National Institute of Allergies and Infectious Diseases and the National Institute of Mental Health have a new research priority: inclusion of terminally ill persons living with HIV in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego for PLWHIV who have a terminal illness, with a prognosis of less than 6 months. As end-of-life HIV cure research is relatively new, the scientific community has a timely opportunity to (...) examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders. EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable. (shrink)

We created Justice: The Game, an educational, role-immersion game designed to be used in philosophy courses. We seek to describe Justice in sufficent detail so that it is understandable to readers not already familiar with role-immersion pedagogy. We hope some instructors will be sufficiently interested in using the game. In addition to describing the game we also evaluate it, thereby highlighting the pedagogical potential of role-immersion games designed to teach political philosophy. We analyze the game by drawing on our observations (...) as designers and playtesters of Justice, along with feedback from students obtained in focus-groups conducted shortly after playtesting ended. We present evidence that Justice, compared to conventional instructional methods alone, plausibly enhances student learning of philosophical skills and content by requiring them to practice those skills and put their content-area knowledge to use in a highly-motivating and engaging context.

In this paper we argue that Steglich-Petersen’s response to Owens’ Exclusivity Objection does not work. Our first point is that the examples Steglich-Petersen uses to demonstrate his argument do not work because they employ an undefended conception of the truth aim not shared by his target (and officially eschewed by Steglich-Petersen himself). Secondly we will make the point that deliberating over whether to form a belief about p is not part of the belief forming process. When an agent enters into (...) this process of deliberation, he has not, contra Steglich-Petersen, already adopted the truth aim with regard to p. In closing, we further suggest that proponents of the truth aim hypothesis need to focus on aim-guidance, not mere aim attribution, for their approach to have explanatory utility so underlining the significance of Owens’ argument.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

The image is the raw material of the twenty-first century. Images infiltrate all social and cultural spaces. Its digital-mediated realities drive communication, industry and knowledge. Images saturate life and adolescent learners are familiar with the participatory nature of image production and its social, educational and personal communicative realities. Vision and visibility, seeing and being now dominate how we inter-subjectively recognise ourselves and perform our world. We also find our aesthetic and embodied self increasingly constituted within imaging acts that are relational. (...) Visual culture may have colonised the self and learning, but imagination is without borders. The current pictorial turn opens possibilities to explore truth in flux through visual artistic acts. This article embeds Deleuzian method, which is one of intuitions, going beyond the actual, or our limited forms of representing life, to recognising that life has future imaginative potential forms and is always becoming. The article discusses an arts-based inquiry project for gifted artist visualiser/learners at an Australian regional university who are given broad topics on science phenomena and asked to give them expression. It suggests that pedagogies of the visual with their performative acts can prise open curriculum where an art-science interchange between two disciplines is made difficult by the current siloed nature of curriculum knowledge. Drawing on an analysis of Anika’s and Joel’s artworks and visual diaries it aims to reveal how their learning events dwell and are performed in aesthetic borderlands and how visual pedagogies forge new fluid visual borderlands and new learning.

Historical accounts of biological function are thought to have, as a point in their favour, their being able to accommodate malfunction. Recently, this has been brought into doubt by Paul Sheldon Davies’s argument for the claim that both selected malfunction (that of the selected functions account) and weak etiological malfunction (that of the weak etiological account), are impossible. In this paper I suggest that in light of Davies’s objection, historical accounts of biological function need to be adjusted to accommodate malfunction. (...) I propose a historical account which places two conditions on membership of a functional kind. My claim is that it is in virtue of a trait’s meeting these conditions that it is a member of a functional kind, and can thus malfunction. I suggest that a version of my proposal can be adopted by both the selected effects and weak etiological theorists, and so conclude that such a proposal meets Davies’s objection. (shrink)

Behavioral evidence for the COVIS dual‐process model of category learning has been widely reported in over a hundred publications (Ashby & Valentin, ). It is generally accepted that the validity of such evidence depends on the accurate identification of individual participants' categorization strategies, a task that usually falls to Decision Bound analysis (Maddox & Ashby, ). Here, we examine the accuracy of this analysis in a series of model‐recovery simulations. In Simulation 1, over a third of simulated participants using an (...) Explicit (conjunctive) strategy were misidentified as using a Procedural strategy. In Simulation 2, nearly all simulated participants using a Procedural strategy were misidentified as using an Explicit strategy. In Simulation 3, we re‐examined a recently reported COVIS‐supporting dissociation (Smith et al., ) and found that these misidentification errors permit an alternative, single‐process, explanation of the results. Implications for due process in the future evaluation of dual‐process theories, including recommendations for future practice, are discussed. (shrink)

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

This is the first of two volumes of essays in commemoration of Alan Turing, whose pioneering work in the theory of artificial intelligence and computer science continues to be widely discussed today. A group of prominent academics from a wide range of disciplines focus on three questions famously raised by Turing: What, if any, are the limits on machine `thinking'? Could a machine be genuinely intelligent? Might we ourselves be biological machines, whose thought consists essentially in nothing more than the (...) interaction of neurons according to strictly determined rules? The discussion of these fascinating issues is accessible to non-specialists and stimulating for all readers. (shrink)

This paper explores the benefits of video feedback for teaching philosophy. Our analysis, based on results from a self-report student survey along with our own experience, indicates that video feedback possesses a number of advantages over traditional written comments. In particular we argue that video feedback is conducive to providing high-quality formative feedback, increases detail and clarity, and promotes student engagement. In addition, we argue that the advantages of video feedback make the method an especially apt tool for addressing challenges (...) germane to teaching philosophy. Video feedback allows markers to more easily explain and illustrate philosophical goals and methods. It allows markers to model the doing of philosophy and thereby helps students to see philosophy’s value. Video feedback is a promising tool for addressing both cognitive and affective barriers to learning philosophy. Such advantages are especially valuable in the context of a student-centered, intentional learning framework. In light of these advantages, we find that video feedback is underappreciated and underutilized. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

In professional soccer, players, coaches, and researchers alike recognize the importance of cognitive skills. Research addressing the relevance of cognitive skills has been based on the cognitive component skills approach or the expert performance approach. Our project aimed to combine the strengths of both approaches to develop and validate cognitive tasks measuring inhibition and cognitive flexibility in a soccer-specific setting with a soccer-specific motor response. In the main study 77 elite youth soccer players completed a computerized version of the standard (...) flanker and number–letter tasks as well as flanker and number–letter tasks requiring a soccer-specific motor response in a soccer-specific setting. Results show good reliability for both tasks. For the SoccerBot360 number–letter task, switch effects for response times and accuracy and acceptable convergent validity were shown. A flanker effect for response time but not accuracy was apparent. Due to no acceptable convergent validity, the flanker task was revised and 63 adult soccer players participated in a follow-up validation study in the SoccerBot100. The revised flanker task showed the flanker effect for response time, but not for accuracy. However, acceptable convergent validity for response time was present. Thus, the soccer-specific number–letter and to some extent the soccer-specific flanker task show potential to be used as a valid cognitive diagnostic tool by soccer clubs. (shrink)

How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours (...) to be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define "the predictive brain." What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

The original essays in this volume present new research on unstructured theories of content, which have traditionally played a central role in linguistics and philosophy of language. The volume explores a wide range of themes related to unstructured content, including both the continued controversy over whether unstructured theories individuate contents too coarsely and various applications of unstructured theories to topics like rationality, epistemic commitment, semantic expressivism, relevance, and propositional attitude ascriptions. It contains contributions from different theoretical perspectives, including both those (...) sympathetic to unstructured theories of content and those who are skeptical, as well as from different methodological backgrounds, with philosophy, logic, and linguistics all represented. With contributions from leading scholars in philosophy and linguistics, this volume will be of interest to anyone working in logic, metaphysics, or the philosophy of mind. (shrink)

Aesthetics and Music is a rich and interesting study. Hamilton's approach is innovative. He interleaves chapters on the history of philosophical thought about music with more theoretical discussions of music, sound, rhythm and improvisation, but does not cover the work–performance relation, depiction or expression. He draws on an atypically broad range of examples, including avant-garde, medieval, non-Western and jazz. The assumptions are humanist: ‘I wish to argue for an aesthetic conception of music as an art … according to which music (...) is a human activity grounded in the body and bodily movement and interfused with human life’.The historical chapters are valuable and not without analysis and criticism. Hamilton shows how the ancient Greek theorists were more interested in music's mathematical properties as reflecting the underlying harmony of relations between cosmic bodies than in the practice of musicians. While they equated the value of art with its contribution to an education for citizenship and while their concept of the arts differed …. (shrink)

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

Their topics cover virtually every philosophical field, and such that each is connected to gay and lesbian studies. Topics include how we are to understand sexual orientation, whether same-sex leads to polygamy, teaching gay studies to undergraduates, promiscuity and virtue, the "war on terror" and gay oppression, the rationality of coming out, the (...) ethics of outing, connections between being gay and being happy, and last, but not least, dignity and being gay.

Humans spend large portions of their time and energy talking to one another, yet it remains unclear whether this activity is primarily selfish or altruistic. Here, it is shown how parent‐of‐origin specific gene expression—or “genomic imprinting”—may provide an answer to this question. First, it is shown why, regarding language, only altruistic or selfish scenarios are expected. Second, it is pointed out that an individual's maternal‐origin and paternal‐origin genes may have different evolutionary interests regarding investment into language, and that this intragenomic (...) conflict may drive genomic imprinting which—as the direction of imprint depends upon whether investment into language is relatively selfish or altruistic—may be used to discriminate between these two possibilities. Third, predictions concerning the impact of various mutations and epimutations at imprinted loci on language pathologies are derived. In doing so, a framework is developed that highlights avenues for using intragenomic conflicts to investigate the evolutionary drivers of language. (shrink)

Overestimation of one’s ability to argue their position on socio-political issues may partially underlie the current climate of political extremism in the U.S. Yet very little is known about what factors influence overestimation in argumentation of socio-political issues. Across three experiments, emotional investment substantially increased participants’ overestimation. Potential confounding factors like topic complexity and familiarity were ruled out as alternative explanations. Belief-based cues were established as a mechanism underlying the relationship between emotional investment and overestimation in a measurement-of-mediation and manipulation-of-mediator (...) design. Representing a new bias blind spot, participants believed emotional investment helps them argue better than it helps others ; where in reality emotional investment harmed or had no effect on argument quality. These studies highlight misguided beliefs about emotional investment as a factor underlying metacognitive miscalibration in the context of socio-political issues. (shrink)

Very often, different people, with different constitutions and comic sensibilities, will make divergent, conflicting judgments about the comic properties of a given person, object, or event, on account of those differences in their constitutions and comic sensibilities. And in many such cases, while we are inclined to say that their comic judgments are in conflict, we are not inclined to say that anybody is in error. The comic looks like a poster domain for the phenomenon of faultless disagreement. I argue (...) that the kind of theory that does the best job of accounting for the appearance of faultless disagreement is a de se version of a response-dependence account, according to which thinking that x is funny is self-attributing a property of the type, being disposed to have R to x in C.

I argue that a theory according to which some of the content of perception is self-locating gives us the resources to cash out the central thought behind projectivism, without having to go in for an error theory about the projected qualities. I first survey some of the phenomena that might motivate what I take to be the central projectivist thought, and then look at some ways of cashing out just what it would amount to for the thought to be correct. (...) I make some objections to some of the standard sorts of projectivist accounts, and then advocate another way of cashing out the thought that I think, at least in certain cases, does a better job of both capturing the phenomena and underwriting the projectivist idea.

Why do humans reason? Many animals draw inferences, but reasoning—the tendency to produce and respond to reason-giving performances—is biologically unusual, and demands evolutionary explanation. Mercier and Sperber advance our understanding of reason’s adaptive function with their argumentative theory of reason. On this account, the “function of reason is argumentative… to devise and evaluate arguments intended to persuade.” ATR, they argue, helps to explain several well-known cognitive biases. In this paper, I develop a neighboring hypothesis called the intention alignment model and (...) contrast it with ATR. I conjecture that reasoning evolved primarily because it helped social hominins more readily and fully align their intentions. We use reasons to advance various proximal ends, but in the main, we do it to overwrite the beliefs and desires of others: to get others to think like us. Reason afforded our ancestors a powerful way to build and maintain the shared outlooks necessary for a highly collaborative existence. Yes, we sometimes argue so as to gain argumentative advantage over others, or otherwise advantage ourselves at the expense of those we argue with, but more often, we reason in ways that are mutually advantageous. In fact, there are excellent reasons for thinking this must be so. IAM, I suggest, neatly explains the available evidence, while also providing a more coherent account of reason’s origins. (shrink)

Bobier argued that hope is necessary for practical deliberation. I will demonstrate that Bobier’s argument for this thesis fails.

There is a strong pull to the idea that there is some metaphysically interesting distinction between the fully real, objective, observer‐independent qualities of things as they are in themselves, and the less‐than‐fully‐real, subjective, observer‐dependent qualities of things as they are for us. Call this (putative) distinction the primary/secondary quality distinction. The distinction between primary and secondary qualities is philosophically interesting because it is (a) often quite attractive to draw such a distinction, and (b) incredibly hard to spell it out in (...) any kind of satisfying and sensible way. I attempt such a spelling‐out after first trying to pin down in more detail what we want from the primary/secondary quality distinction, and saying a bit about why that is such a hard thing to get.

In this book, Andy Mueller examines the ways in which epistemic and practical rationality are intertwined. In the first part, he presents an overview of the contemporary debates about epistemic norms for practical reasoning, and defends the thesis that epistemic rationality can make one practically irrational. Mueller proposes a contextualist account of epistemic norms for practical reasoning and introduces novel epistemic norms pertaining to ends and hope. In the second part Mueller considers current approaches to pragmatic encroachment in epistemology, (...) ultimately arguing in favor of a new principle-based argument for pragmatic encroachment. While the book defends tenets of the knowledge-first programme, one of its main conclusions is thoroughly pragmatist: in an important sense, the practical has primacy over the epistemic. (shrink)

“There’s no disputing about taste.” That’s got a nice ring to it, but it’s not quite the ring of truth. While there’s definitely something right about the aphorism – there’s a reason why it is, after all, an aphorism, and why its utterance tends to produce so much nodding of heads and muttering of “just so” and “yes, quite” – it’s surprisingly difficult to put one’s finger on just what the truth in the neighborhood is, exactly. One thing that’s pretty (...) clear is that what’s right about the aphorism, that there’s no disputing about taste, isn’t that there’s no disputing about taste. There’s heaps of disputing about taste. People engage in disputes about which movies, music, paintings, literature, meals, furniture, architectural styles, etc. are good, beautiful, tasty, fun, elegant, ugly, disgusting, etc. all the time. This is obvious to anyone who has watched dueling-movie-critics shows, read theater reviews, or negotiated with a group or partner about which movie or restaurant to go to, or which sofa or painting to put in the living room. It takes great care and good aim to fling a brick without hitting somebody who’s engaged in a dispute about taste. (shrink)
