Balance and common sense are commonplace concepts used to bring an audience to a place of shared understanding. These commonplaces also function as decision-making heuristics. I argue in this paper that the commonplaces ?balance? and ?common sense? are problematic because they suggest decision-making strategies that strip associated information of complexity and value. Through an examination of theory and responses to interviews conducted in relation to an ongoing project on environmental rhetoric, I problematize these concepts and consider how awareness of the (...) interaction of these commonplaces and heuristics can benefit rhetors and agencies seeking environmental change.

This paper explores care ethics and the roles that power, trust, and stereotypes play in establishing and building caring relationships. The work is the result of the evolution of collaboration between teacher and student as that teacher/student dichotomy evolved to one of shared trust and respect and considers the oft-neglected aspect of respect in an ethic of care. By tracing the evolution of the authors’ relationship, we argue that mutual respect in an ethic of care has the potential to enrich (...) our interactions and reshape the way we think about care from primarily unilinear to a more reciprocal model. We propose a modified ethic of care based on mutual trust as a working model for ethics of care-based relationships, particularly with regard to student-teacher interactions, but also perhaps to more broadly extend into our daily interactions with others.

Despite its importance, abnormal interactions between the proximal and distal upper extremity muscles of stroke survivors and their impact on functional task performance has not been well described, due in part to the complexity of upper extremity tasks. In this pilot study, we elucidated proximal–distal interactions and their functional impact on stroke survivors by quantitatively delineating how hand and arm movements affect each other across different phases of functional task performance, and how these interactions are influenced by stroke. Fourteen subjects, (...) including nine chronic stroke survivors and five neurologically-intact subjects participated in an experiment involving transport and release of cylindrical objects between locations requiring distinct proximal kinematics. Distal kinematics of stroke survivors, particularly hand opening, were significantly affected by the proximal kinematics, as the hand aperture decreased and the duration of hand opening increased at the locations that requires shoulder abduction and elbow extension. Cocontraction of the extrinsic hand muscles of stroke survivors significantly increased at these locations, where an increase in the intermuscular coherence between distal and proximal muscles was observed. Proximal kinematics of stroke survivors was also affected by the finger extension, but the cocontraction of their proximal muscles did not significantly increase, suggesting the changes in the proximal kinematics were made voluntarily. Our results showed significant proximal-to-distal interactions between finger extension and elbow extension/shoulder abduction of stroke survivors exist during their functional movements. Increased cocontraction of the hand muscles due to increased neural couplings between the distal and proximal muscles appears to be the underlying mechanism. (shrink)

Though emotional faces preferentially reach awareness, the present study utilised both objective and subjective indices of awareness to determine whether they enhance subjective awareness and “blindsight”. Under continuous flash suppression, participants localised a disgusted, fearful or neutral face (objective index), and rated their confidence (subjective index). Psychopathic traits were also measured to investigate their influence on emotion perception. As predicted, fear increased localisation accuracy, subjective awareness and “blindsight” of upright faces. Coldhearted traits were inversely related to subjective awareness, but not (...) “blindsight”, of upright fearful faces. In a follow-up experiment using inverted faces, increased localisation accuracy and awareness, but not “blindsight”, were observed for fear. Surprisingly, awareness of inverted fearful faces was positively correlated with coldheartedness. These results suggest that emotion enhances both pre-conscious processing and the qualitative experience of awareness, but that pre-conscious and conscious processing of emotional faces rely on at least partially dissociable cognitive mechanisms.

The discovery of traces of a blood meal in the abdomen of a 50‐million‐year‐old mosquito reminds us of the insights that the chemistry of fossils can provide. Ancient DNA is the best known fossil molecule. It is less well known that new fossil targets and a growing database of ancient gene sequences are paralleled by discoveries on other classes of organic molecules. New analytical tools, such as the synchrotron, reveal traces of the original composition of arthropod cuticles that are more (...) than 400 my old. Pigments such as melanin are readily fossilized, surviving virtually unaltered for ∼200 my. Other biomarkers provide evidence of microbial processes in ancient sediments, and have been used to reveal the presence of demosponges, for example, more than 635 mya, long before their spicules appear in the fossil record. Ancient biomolecules are a powerful complement to fossil remains in revealing the history of life. (shrink)

Cognitive control refers to the regulation of mental activity to support flexible cognition across different domains. Cragg and Nation (2010) propose that the development of cognitive control in children parallels the development of language abilities, particularly inner speech. We suggest that children’s late development of cognitive control also mirrors their limited ability to revise misinterpretations of sentence meaning. Moreover, we argue that for certain tasks, a tradeoff between bottom-up (data-driven) and top-down (rule-based) thinking may actually benefit performance in both children (...) and adults. Specifically, we propose that a lack of cognitive control may promote important aspects of cognitive development, like language acquisition and creativity. (shrink)

Conversion to sound at the close of the 1920s ushered in a decade-long period of French film production that standard accounts by Alan Williams and Colin Crisp cast as all but unparalleled in aesthetic impact and thematic scope. Despite chronic underfunding and structural disarray in an industry that never fully rebounded after the Great War, French audiences enjoyed a robust domestic culture of stars, screenwriters, and directors whose concern for richly detailed narratives and moody “atmospherics” laid the foundations for the (...) classic French cinema.

The sudden appearance in the fossil record of the major animal phyla apparently records a phase of unparalleled, rapid evolution at the base of the Cambrian period, 545 Myr ago. This has become known as the Cambrian evolutionary ‘explosion’, and has fuelled speculation about unique evolutionary processes operating at that time. The acceptance of the palaeontological evidence as a true reflection of the evolutionary narrative has been criticised in two ways: from a reappraisal of the phylogenetic relationships of the early (...) fossils, and from predicitions of molecular divergence times, based on six appropriate metazoan genes. Phylogenetic analysis of the arthropods implies an earlier, Precambrian history for most clades, and hence an extensive period of cladogenesis unrecorded by fossils. A similar argument can be applied to molluscs, lophophorates and deuterostomes. Molecular evidence implies divergence between clades to at least 1000 Myr ago. The apparent paradox between the sudden appearance of recognisable metazoans and their extended evolutionary history might be explained by a sudden Cambrian increase in body size, which was accompanied by skeletisation. A new paradigm suggests that the ‘explosion’ in the record may have been decoupled from the evolutionary innovation. (shrink)

This chapter defends a view of semantics on which developing a semantic theory closely resembles developing a scale of measurement. The view helps explain how semantics has made so much progress despite deep disagreements about the target of semantic theorizing (e.g., between those who maintain that semantics is characterizing something psychological, and those who maintain that it is characterizing something social), how appeals to set-theoretic abstracta make sense despite Benacerraf-style worries and despite the fact that set-theoretic entities fit badly with (...) standard (e.g., causal) metasemantic views, and why the threat of radical context sensitivity does not undermine the semantic project.

A recent article argued that signals from conventional Raman spectroscopy of organic materials are overwhelmed by edge filter and fluorescence artefacts. The article targeted a subset of Raman spectroscopic investigations of fossil and modern organisms and has implications for the utility of conventional Raman spectroscopy in comparative tissue analytics. The inferences were based on circular reasoning centered around the unconventional analysis of spectra from just two samples, one modern, and one fossil. We validated the disputed signals with in situ Fourier‐Transform (...) Infrared (FT‐IR) Spectroscopy and through replication with different lasers, filters, and operators in independent laboratories. Our Raman system employs a holographic notch filter which is not affected by edge filter or other artefacts. Multiple lines of evidence confirm that conventional Raman spectra of fossils contain biologically and geologically meaningful information. Statistical analyses of large Raman and FT‐IR spectral data sets reveal patterns in fossil composition and yield valuable insights into the history of life. (shrink)

One of the central debates within contemporary Anglo-American political philosophy concerns how to formulate an egalitarian theory of distributive justice which gives coherent expression to egalitarian convictions and withstands the most powerful anti-egalitarian objections. This book brings together many of the key contributions to that debate by some of the world’s leading political philosophers: Richard Arneson, G.A. Cohen, Ronald Dworkin, Thomas Nagel, Derek Parfit, John Rawls, T.M. Scanlon, and Larry Temkin.

I defend indirect perceptual realism against two recent and related charges to it offered by A. D. Smith and P. Snowdon, both stemming from demonstrative reference involving indirect perception. The needed aspects of the theory of demonstratives are not terribly new, but their connection to these objections has not been discussed. The groundwork for my solution emerges from considering normal cases of indirect perception (e.g., seeing something depicted on a television) and examining the role this indirectness plays in demonstrative assertions. (...) I argue that indirectness routinely if not typically plays a justificatory role in such judgements, and not a semantic one, and that the same can be said of such judgements when considered within the indirect realist framework. The denial of this, on my analysis, is essential to the criticisms of Snowdon and Smith. The discussion is extended to include scenarios involving the sorts of misconceptions Smith employs. (shrink)

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

Loosely put, colour constancy for example occurs when you experience a partly shadowed wall to be uniformly coloured, or experience your favourite shirt to be the same colour both with and without sunglasses on. Controversy ensues when one seeks to interpret ‘experience’ in these contexts, for evidence of a constant colour may be indicative a constant colour in the objective world, a judgement that a constant colour would be present were things thus and so, et cetera. My primary aim is (...) to articulate a viable conception of Present Constancy, of what occurs when a constant colour is present in experience, despite the additional presence of some experienced colour variation (e.g., correlating to a change in illumination). My proposed conception involves experienced colour layering – experiencing one opaque colour through another transparent one – and in particular requires one of those experienced layers to remain constant while the other changes. The aim is not to propose this layering conception of colour constancy as the correct interpretation of all constancy cases, but rather to develop the conception enough to demonstrate how it could and plausibly should be applied to various cases, and the virtues it has over rivals. Its virtues include a seamless application to constancy cases involving variations in filters (e.g., sunglasses) and illuminants; its ability to accommodate experiences of partial colours and error-free interpretations of difficult cases; and its broad theoretical-neutrality, allowing it to be incorporated into numerous perceptual epistemologies and ontologies. If layered constancy is prevalent, as I suspect it is, then our experiential access to colours is critically nuanced: we have been plunged into a world of colour without being told that we will rarely, if ever, look to a location and experience just one of them.

One of the first questions that paleontologists ask when they identify a large-scale trend in the fossil record (e.g., size increase, complexity increase) is whether it is passive or driven. In this article, I explore two questions about driven trends: (1) what is the underlying cause or source of the directional bias? and (2) has the strength of the directional bias changed over time? I identify two underdetermination problems that prevent scientists from giving complete answers to these two questions.

Quantities like mass and temperature are properties that come in degrees. And those degrees (e.g. 5 kg) are properties that are called the magnitudes of the quantities. Some philosophers (e.g., Byrne 2003; Byrne & Hilbert 2003; Schroer 2010) talk about magnitudes of phenomenal qualities as if some of our phenomenal qualities are quantities. The goal of this essay is to explore the anti-physicalist implication of this apparently innocent way of conceptualizing phenomenal quantities. I will first argue for a metaphysical thesis (...) about the nature of magnitudes based on Yablo’s proportionality requirement of causation. Then, I will show that, if some phenomenal qualities are indeed quantities, there can be no demonstrative concepts about some of our phenomenal feelings. That presents a significant restriction on the way physicalists can account for the epistemic gap between the phenomenal and the physical. I’ll illustrate the restriction by showing how that rules out a popular physicalist response to the Knowledge Argument. (shrink)

Sensory substitution devices (SSDs) are most familiar from their use with subjects who are deficient in a target modality (e.g. congenitally blind subjects), but there is no doubt that the use and potential value of SSDs extend to persons without such deficits. Recent work by Amedi and his team (in particular Levy-Tzedek et al. 2012) has begun to explore this. Their idea is that SSDs may facilitate behavioural transference (BT) across sense modalities. In this case, a motor skill learned through (...) visual perception might be subsequently employed in response to auditory perception, using an SSD as a mediator. They infer from the existence of such BT that the learned skill is amodally represented. After a brief overview I identify ways to more fully test for BT within this experimental paradigm and argue that their conclusion about amodal representation is premature. Additionally, I argue that their preferred SSD (Eyemusic) is of limited value for the project. While my remarks are critical, my intention is to be constructive, particularly in light of the fact that Levy-Tzedek et al. (2012), is, I believe, the first output from Amedi's lab concerning this line of research. (shrink)

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other (...) populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

With characteristic candour, David Hume is prepared to admit that in ordinary life, but certainly not when reflecting on the nature of perceptual experience, he has no option but to ‘believe in the existence of body’ despite his philosophical reasonings to the contrary. In this instance, his commitment to ‘Common Sense’ has become, as it was not to become for his contemporary Thomas Reid, a direct consequence of participating in a day-to-day existence if nevertheless one which he has no option (...) but to reject when reflecting in the study.Ludwig Wittgenstein, on the other hand, presents us with a picture of what has come to be regarded as a form of Humean ‘phenomenalist language’, private in nature, which, in one of the most famous passages of his later philosophy, he appears to reject via a form of reductio ad absurdum argument. In what follows, it will be questioned whether his ‘argument’ clearly represents phenomenalist proposals which Hume’s successors, e. g., A.J. Ayer, accepted without question. If there is a misunderstanding here on both sides, an investigation into its nature must lead to an appreciation of the varying roles attributed by these philosophers to the notion of ‘Common Sense’.

The ‘Private Language’ sections of the Philosophical Investigations §§ 243–315 serve to undermine the idea that our ordinary felt sensations, e.g., of heat, or cold, or pain, together with our experienced impressions of colour or of sound, are ‘private’ or ‘inner’ objects, where an object mirrors in the mental realm what we associate with that of the physical. This paper explores Wittgenstein's method in these sections, together with the work of several of his commentators who agree with his ‘therapeutic’ approach (...) to the denial of a possible private language. More significantly, however, it discovers a paradox in the fact that a number of philosophers who claim that his ‘Argument Against Private Language’ is unsuccessful point in reaching this conclusion to the very features concerning first-person sensation ascription that Wittgenstein employs to reveal that our ordinary sensations are not ‘private’ to us in that sense identified in § 243, which talks of ‘a language used to refer to what only its speaker can know’, viz, ‘his immediate private sensations’. This helps to explain why there is still no general agreement on the significance of §§ 243–315. (shrink)

The nature of Marx's ethics has been a matter of considerable dispute since the latter part of the nineteenth century. Some have maintained that Marx had no ethics; others have claimed that his ethics is Kantian; and yet others have maintained that his ethics is utilitarian. The first two views were prominent at the turn of the century. It is the utilitarian view that seems to hold favor among a great many today. Thus Adam Schaff has claimed that ‘Marxist theory (...) … leads to the general position that may be called “social hedonism” —the view that the aim of human life is to secure the maximum happiness for the broadest masses of the people … ’ Similarly, Derek Allen has claimed that ‘it is possible … to show that the arguments which support [Marx's and Engels’] moral judgments are utilitarian in all but name.’.

Søren Kierkegaard is well-known as an original philosophical thinker, but less known is his reliance upon and development of the Christian tradition of the Seven Deadly Sins, in particular the vice of acedia, or sloth. As acedia has enjoyed renewed interest in the past century or so, commentators have attempted to pin down one or another Kierkegaardian concept (e.g., despair, heavy-mindedness, boredom, etc.) as the embodiment of the vice, but these attempts have yet to achieve any consensus. In our estimation, (...) the complicated reality is that, in using slightly different but related concepts, Kierkegaard is providing a unique look at acedia as it manifests differently at different stages on life’s way. Thus, on this “perspectival account”, acedia will manifest differently according to whether an individual inhabits the aesthetic, ethical, or religious sphere. We propose two axes for this perspectival account. Such descriptions of how acedia manifests make up the first, phenomenal axis, while the second, evaluative axis, accounts for the various bits of advice and wisdom we read in the diagnoses of acedia from one Kierkegaardian pseudonym to another. Our aim is to show that Kierkegaard was not only familiar with the concept of acedia, but his contributions helped to develop and extend the tradition. (shrink)

Revisionary theories of logic or truth require revisionary theories of mind. This essay outlines nonclassically based theories of rational belief, desire, and decision making, singling out the supervaluational family for special attention. To see these nonclassical theories of mind in action, this essay examines a debate between David Lewis and Derek Parfit over what matters in survival. Lewis argued that indeterminacy in personal identity allows caring about psychological connectedness and caring about personal identity to amount to the same thing. (...) The essay argues that Lewis's treatment of two of Parfit's puzzle cases—degreed survival and fission—presuppose different nonclassical treatments of belief and desire. (shrink)

ABSTRACTI consider objections to the use of living wills based upon the discontinuity of personal identity between the time of the execution of the directive anbd the time the person becomes incompetent. Recent authors, following Derek Parfit's “Complex View” of personal identity, have argued that there is often not sufficient identity interests between the competent person who executes the living will and the incompetent patient to warrant the use of the advance directive. I argue that such critics err by (...) seeking personal identity in a purely descriptive manner. By exploring Buchanan and Brock's concept of “surviving interests”, an argument is developed that certain future‐oriented acts have a normative force that contributes to the narrative unity which is constitutive of personal ideality. This narrative concept of the self is entailed by many of the our ordinary practices and challenges the philosophical consensus to view the self in a more dynamic and communitarian manner. (shrink)
