This article critically examines the recent papal allocution on patients in a persistent vegetative state with regard to the appropriate conditions for considering “reformable statements.” In the first part of the article, the purpose and meaning of the allocution are assessed. O'Rourke concludes that given consideration of the individual patient's best interest, prolonging artificial nutrition and hydration is not, in every case, the best option. Although he stresses favorability for preservation of the life of the patient through artificial nutrition and (...) hydration, costs and benefits to the patient should be weighed. Ultimately, he argues in favor of leaving the decision to the patient, his caregivers, and others immediately involved in the case. (shrink)

Zuidema et al. illustrate how empirical AGL studies can benefit from computational models and techniques. Computational models can help clarifying theories, and thus in delineating research questions, but also in facilitating experimental design, stimulus generation, and data analysis. The authors show, with a series of examples, how computational modeling can be integrated with empirical AGL approaches, and how model selection techniques can indicate the most likely model to explain experimental outcomes.

The thought of G. W. F. Hegel has had a deep and lasting influence on a wide range of philosophical, political, religious, aesthetic, cultural and scientific movements. But, despite the far-reaching importance of Hegel's thought, there is often a great deal of confusion about what he actually said or believed. This is an invaluable introduction for philosophical beginners and a useful reference source for more advanced scholars and researchers.

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

The paper proposes a way of bridging the gapbetween physical processes in the brain and the ''''felt''''aspect of sensory experience. The approach is based onthe idea that experience is not generated by brainprocesses themselves, but rather is constituted by theway these brain processes enable a particular form of''''give-and-take'''' between the perceiver and theenvironment. From this starting-point we are able tocharacterize the phenomenological differences betweenthe different sensory modalities in a more principledway than has been done in the past. We are also (...) ableto approach the issues of visual awareness andconsciousness in a satisfactory way. Finally weconsider a number of testable empirical consequences,one of which is the striking prediction of thephenomenon of ''''change blindness''''. (shrink)

Higher education institutions are increasingly relying on learning analytics to collect voluminous amounts of data ostensibly to inform student learning interventions. The use of learning analytics, however, can result in a tension between the Council for the Advancement of Standards in Higher Education (CAS) principles of autonomy and non-malfeasance on the one hand, and the principle of beneficence on the other. Given the complications around student privacy, informed consent, and data justice in addition to the potential to do harm, many (...) current practices around learning analytics within higher education can be considered to be in violation of CAS standards. This paper aims to explore this tension in greater detail and argues that the student voice offers a promising way to ensure that students’ autonomy is respected, harm is reduced, and that higher education institutions can still fulfil the principle of beneficence.

Observers inspected normal, high quality color displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve "Central Interest" or "Marginal Interest" locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as determined by luminance, color, and position of the Central and Marginal interest changes were equalized. -/- The results obtained were very similar to those obtained in (...) prior experiments showing failure to detect changes occurring simultaneously with saccades, flicker, or “mudsplashes” in the visual scene: Many changes were very hard to detect, and Marginal Interest changes were harder to detect than Central Interest changes. -/- Analysis of eye movements showed, as expected, that the probability of detecting a change depended on the eye’s distance from the change location. However a surprising finding was that both for Central and Marginal Interest changes, evenwhen observers were directly fixating the change locations (within 1 degree),more than 40% of the time they still failed to see the changes. It seems that looking at something does not guarantee you “ see” it. (shrink)

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory (NCT) is that acquired characters play an evolutionary (...) role through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

Change-blindness occurs when large changes are missed under natural viewing conditions because they occur simultaneously with a brief visual disruption, perhaps caused by an eye movement, a flicker, a blink, or a camera cut in a film sequence. We have found that this can occur even when the disruption does not cover or obscure the changes. When a few small, high-contrast shapes are briefly spattered over a picture, like mudsplashes on a car windscreen, large changes can be made simultaneously in (...) the scene without being noticed.

The discovery and ongoing investigation of microRNAs suggest important conceptual and methodological lessons for philosophers and historians of biology. This paper provides an account of miRNA research and the shift from viewing these tiny regulatory entities as minor curiosities to seeing them as major players in the post-transcriptional regulation of genes. Conceptually, the study of miRNAs is part of a broader change in understandings of genetic regulation, in which simple switch-like mechanisms were reinterpreted as aspects of complex cellular and genome-wide (...) processes. Among them are the activities of small RNAs, previously regarded as non-functional. Methodologically, the miRNA story suggests new ways of characterizing biological research that should prove helpful to philosophers of science who seek to develop more pluralistic, pragmatic models of scientific inquiry. miRNA research displays iterative movements between multiple modes of investigation that include not only the proposal and testing of hypotheses but also exploratory, technology-oriented and question-driven modes of research. As an exemplary story of scientific discovery and development, the miRNA case illustrates transitions from genetics to genomics and systems biology, and it shows how diverse configurations of research practice are related to major scientific advances.

The most important clarification we bring in our reply to commentators concerns the problem of the “explanatory gap”: that is, the gulf that separates physical processes in the brain from the experienced quality of sensations. By adding two concepts (bodiliness and grabbiness) that were not stressed in the target article, we strengthen our claim and clarify why we think we have solved the explanatory gap problem, – not by dismissing qualia, but, on the contrary, by explaining why sensations have a (...) “feel” and why “feels” feel the way they do. We additionally clarify our views on: internal representations (we claim internal representations cannot explain why sensation has a feel), on behaviorism (we are not behaviorists), on perception and action (we believe there can be perception without action), and on the brain (we believe the brain does do something important in perception). (shrink)

Any theory of experience which postulates that brain mechanisms generate "raw feel" encounters the impassable "explanatory gap" separating physics from phenomenology.

How could neural processes be associated with phenomenal consciousness? We present a way to answer this question by taking the counterintuitive stance that the sensory feel of an experience is not a thing that happens to us, but a thing we do: a skill we exercise. By additionally noting that sensory systems possess two important, objectively measurable properties, corporality and alerting capacity, we are able to explain why sensory experience possesses a sensory feel, but thinking and other mental processes do (...) not. We are additionally able to explain why different sensory feels differ in the way they do. (shrink)

Following arguments put forward in my book (Why red doesn’t sound like a bell: understanding the feel of consciousness. Oxford University Press, New York, USA, 2011), this article takes a pragmatic, scientist’s point of view about the concepts of consciousness and “feel”, pinning down what people generally mean when they talk about these concepts, and then investigating to what extent these capacities could be implemented in non-biological machines. Although the question of “feel”, or “phenomenal consciousness” as it is called by (...) some philosophers, is generally considered to be the “hard” problem of consciousness, the article shows that by taking a “sensorimotor” approach, the difficulties can be overcome. What remains to account for are the notions of so-called “access consciousness” and the self. I claim that though they are undoubtedly very difficult, these are not logically impossible to implement in robots. (shrink)

This study takes a systemic functional multimodal social semiotic approach to the analysis and discussion of image and text relations in two sets of data. First, patterns of contextualisation of images and text in the online magazines Dabiq and Rumiyah produced by the Islamic extremist organisation which refers to itself as Islamic State are examined. The second data set consists of a sample of texts from Western online news and blog sites which include recontextualisations of images found in the first (...) data set. A sample of examples of the use and re-use of images is discussed in order to identify patterns of similarity and difference when images and text are recontextualised. It is argued that the ISIS material tends to foreground the interpersonal metafunction in combination with the textual metafunction, while the other data set tends to foreground the ideational metafunction. These inferences indicate that further exploration of a larger data set is worth pursuing. Such studies would provide deeper insights helping to distinguish between online material which supports terrorism and that which opposes it, as well as facilitating the further development of multimodal social semiotic approaches to image and text relations.

With a few exceptions, Thomists have by and large failed to engage with the historical and hermeneutical turns in philosophy and theology. This article offers an account of what the beginnings of a Thomistic engagement with recent hermeneutical philosophy might look like. In order to develop such an account, the author turns to arguably the most important contemporary hermeneutical philosopher, namely Hans-Georg Gadamer, as a dialogue partner. Despite claims to the contrary, this article argues that Gadamer does not successfully deal (...) with the specter of relativism. It goes on to show how that the thought of Thomas Aquinas can ably deal with this specter. There are two central elements in the argument put forward. Firstly, the author argues that the human being exists in between God as First Efficient Cause of all that exists and God as Final Cause of all that exists. This existence between God as First Efficient Cause of all that exists and God as Final Cause of all that exists furnishes the connatural context in which human knowing and willing unfolds. Secondly, he considers the dynamics of “interinvolvement” between intellect and will. The upshot of these arguments is a construal of reason that is at once capable of universal truth and hermeneutical in nature. Indeed, the universal range of reason and its hermeneutical dimension are in no way opposed to each other: they are rather dual aspects of one and the same reality. (shrink)

Call u the triplet of cone quantum catch for the light that is incident on a surface, and v the triplet of cone quantum catch for the light that is reflected off that surface. Philipona & O'Regan (2006) present results from numerical calculations showing that: 1. each surface can be associated with a 3 by 3 matrix A such that the relation v = A u to a very high degree of accuracy for any natural illuminant, 2. the vast majority (...) of such matrices associated with Munsell chips have three real eigenvalues, 3. Munsell chips that are most often given a name in the World Color Survey are chips whose associated matrices have a singular configuration of eigenvalues, as measured by a "singularity index". The conclusion of the paper is that this striking coincidence lends credence to the idea that data about color naming derive from facts about natural lights, surface reflexion properties, and human photopigments, rather than from facts about neural pathways or cortical representations.

Plato's Bedroom is a book for people who want to be better at falling in love and being in love, with all the ecstasies and dangers erotic life can bring. It is also an inviting book for readers who are intellectually playful and up for a challenge, written with verve, and full of stories thoughtful persons will find to be mirrors of their own erotic selves. Drawing on Greek myth, Plato, Shakespeare, and a wide range of modern literature and movies, (...) the book gets Aphrodite talking with the young lovers in A Midsummer Night's Dream, and lets us listen in on Woody Allen arguing with Othello. The author's account of how we seek, fear, avoid, and sometimes destroy love, is astonishingly fresh and engaging. Throughout its pages, one hears the voice of an engaging teacher and the conversation of a wise friend. In short, this is a work of practical philosophy, not scholarship, though only a scholar could have written it. It invites readers into a deep appreciation of timeless ancient wisdom through reflecting on their own powers for love and their susceptibility to desire. A distinctive feature of the book is the interweaving of two guiding threads in Plato's conception of erotic experience: androgyny, that is, the integration of masculine and feminine; and creativity, in both a sexual and a spiritual sense. These two aspects of Plato's erotic vision, androgyny and creativity, lead readers to a sense of grateful wonder and sacred awe at our own erotic powers. Our natural experience of romantic love, articulated so well by Plato, points toward a more explicitly religious interpretation of love's commitments and pleasures. (shrink)

Abstract:This visual essay invites renewed reflection on the iconography of the people. In the spring of 2020, Guatemala's President Alejandro Giammattei prohibited citizens from leaving their homes to help contain the spread of the novel coronavirus known as Covid-19. Doing little to manage the spread of the virus, these curfew events gave new aesthetic and political meaning to a familiar visual genre: photographs of empty streets. For more than a century, and especially in the summer of 2020, images of crowds (...) and mass protests have provided both governments on the one hand, and protesting multitudes on the other with an aesthetic representation of the people. But this interest in collective assemblies has tended to engage only one side of the equation. To fully appreciate the visual power of the people, it is also necessary to understand those images from which people are strikingly absent. (shrink)

The sensorimotor theory of perceptual consciousness offers a form of enactivism in that it stresses patterns of interaction instead of any alleged internal representations of the environment. But how does it relate to forms of enactivism stressing the continuity between life and mind? We shall distinguish sensorimotor enactivism, which stresses perceptual capacities themselves, from autopoietic enactivism, which claims an essential connection between experience and autopoietic processes or associated background capacities. We show how autopoiesis, autonomous agency, and affective dimensions of experience (...) may fit into sensorimotor enactivism, and we identify differences between this interpretation and autopoietic enactivism. By taking artificial consciousness as a case in point, we further sharpen the distinction between sensorimotor enactivism and autopoietic enactivism. We argue that sensorimotor enactivism forms a strong default position for an enactive account of perceptual consciousness. (shrink)

Researchers have long debated the extent to which an individual’s skin tone influences their perceived race. Brooks and Gwinn demonstrated that the race of surrounding faces can affect the perceived skin tone of a central target face without changing perceived racial typicality, suggesting that skin lightness makes a small contribution to judgments of race compared to morphological cues. However, the lack of a consistent light source may have undermined the reliability of skin tone cues, encouraging observers to rely disproportionately on (...) morphological cues instead. The current study addresses this concern by using 3D models of male faces with typically Black African or White European appearances that are illuminated by the same light source. Observers perceived target faces surrounded by White faces to have darker skin than those surrounded by Black faces, particularly for faces of intermediate lightness. However, when asked to judge racial typicality, a small assimilation effect was evident, with target faces perceived as more stereotypically White when surrounded by White than when surrounded by Black faces at intermediate levels of typicality. This evidence of assimilation effects for perceived racial typicality despite concurrent contrast effects on perceived skin lightness supports the previous conclusion that perceived skin lightness has little influence on judgments of racial typicality for racially ambiguous faces, even when lighting is consistent.

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

Like Saint Paul, I was “born out of due time” insofar as the study of bioethics is concerned. I spent 15 years in teaching and administration at the Aquinas Institute of Theology, then in Dubuque, Iowa, now on the campus of Saint Louis University. I was given a sabbatical study year in 1972–1973 to refresh my mind and spirit. Though my major study and research emphasis prior to the sabbatical study had been in the field of Church law and religious (...) government, I determined to direct my attention to the study of moral theology and ethics, because at that time there was confusion in this area of discipline, especially insofar as the Catholic community was concerned. With this in mind, I chose the University of Chicago as the locale for my study and was awarded a postdoctoral fellowship. (shrink)

Minorities comprise a tiny fraction of media owners, and continued media consolidation exacerbates existing disparities. This article examines this problem by integrating the work of Jurgen Habermas and Jacques Ellul. These theorists identify a common concern—described alternately as technicization and colonization—involving homogenization of content, loss of localism, and decreased ownership diversity. In different ways, each acknowledges the possibility that social action can make a difference. Habermas' discourse ethics provides a normative foundation for arguing on behalf of ownership diversity and policy (...) reform. Though Ellul is skeptical of institutional reform, he offers a complementary vision of concrete action on the part of local, independent community groups. While their solutions are different, we argue that both are necessary. Media reform efforts must incorporate both Habermasian and Ellulian approaches by supplementing federal regulatory reform with independent grassroots activism. A combination of such efforts is essential to the movement's success. (shrink)
