Over 40 years of research have shown that traumatic brain injury affects brain volume. However, technical and practical limitations made it difficult to detect brain volume abnormalities in patients suffering from chronic effects of mild or moderate traumatic brain injury. This situation improved in 2006 with the FDA clearance of NeuroQuant®, a commercially available, computer-automated software program for measuring MRI brain volume in human subjects. More recent strides were made with the introduction of NeuroGage®, commercially available software that is based (...) on NeuroQuant® and extends its utility in several ways. Studies using these and similar methods have found that most patients with chronic mild or moderate traumatic brain injury have brain volume abnormalities, and several of these studies found—surprisingly—more abnormal enlargement than atrophy. More generally, 102 peer-reviewed studies have supported the reliability and validity of NeuroQuant® and NeuroGage®. Furthermore, this updated version of a previous review addresses whether NeuroQuant® and NeuroGage® meet the Daubert standard for admissibility in court. It concludes that NeuroQuant® and NeuroGage® meet the Daubert standard based on their reliability, validity, and objectivity. Due to the improvements in technology over the years, these brain volumetric techniques are practical and readily available for clinical or forensic use, and thus they are important tools for detecting signs of brain injury.

The opening chapter of Genesis makes a lofty claim about the human condition: that humans are created in the image of God. But why can humans image God? This article examines four different interpretations of humans as interpretive animals. Following Martin Heidegger's account of Dasein, I argue that humans are interpretive animals, and as such, are suitable creatures to bear God's image. Humans as interpretive animals function as the image of God, not because of divine fiat; instead, humans in their (...) capacities are open to being the image. My argument is not that the image of God is identifiable as particular human features. Instead, it is the fact that humans have specific capacities that make them interpretive animals (e.g., radical openness, thrownness, malleability) and that these traits are constitutive for what it means to be human. Alongside Heidegger, I draw on the works of Charles Taylor, Claudia Welz, and Kathryn Tanner. (shrink)

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Counters the long-standing, solemn interpretation of Plato’s dialogues with one centered on the philosophical and pedagogical significance of Socrates as a comic figure. Plato was described as a boor and it was said that he never laughed out loud. Yet his dialogues abound with puns, jokes, and humor. Sonja Madeleine Tanner argues that in Plato’s dialogues Socrates plays a comical hero who draws heavily from the tradition of comedy in ancient Greece, but also reforms laughter to be applicable to (...) all persons and truly shaming to none. Socrates introduces a form of self-reflective laughter that encourages, rather than stifles, philosophical inquiry. Laughter in the dialogues—both explicit and implied—suggests a view of human nature as incongruous with ourselves, simultaneously falling short of, and superseding, our own capacities. What emerges is a picture of human nature that bears a striking resemblance to Socrates’ own, laughable depiction, one inspired by Dionysus, but one that remains ultimately intractable. The book analyzes specific instances of laughter and the comical from the Apology, Laches, Charmides, Cratylus, Euthydemus, and the Symposium to support this, and to further elucidate the philosophical consequences of recognizing Plato’s laughter. Sonja Madeleine Tanner is Associate Professor of Philosophy at the University of Colorado, Colorado Springs, and the author of In Praise of Plato’s Poetic Imagination. (shrink)

In this undergraduate textbook Lewis R. Gordon offers the first comprehensive treatment of Africana philosophy, beginning with the emergence of an Africana consciousness in the Afro-Arabic world of the Middle Ages. He argues that much of modern thought emerged out of early conflicts between Islam and Christianity that culminated in the expulsion of the Moors from the Iberian Peninsula, and from the subsequent expansion of racism, enslavement, and colonialism which in their turn stimulated reflections on reason, liberation, and the (...) meaning of being human. His book takes the student reader on a journey from Africa through Europe, North and South America, the Caribbean, and back to Africa, as he explores the challenges posed to our understanding of knowledge and freedom today, and the response to them which can be found within Africana philosophy.

In this paper I will examine two responses to the argument from marginal cases; the argument from kinds and the similarity argument. I will argue that these arguments are insufficient to show that all humans have moral status but no animals do. This does not prove that animals have moral status but it does shift the burden of proof onto those who want to maintain that all humans are morally considerable, but no animals are.

The intellectual history of the last quarter of this century has been marked by the growing influence of Africana thought--an area of philosophy that focuses on issues raised by the struggle over ideas in African cultures and their hybrid forms in Europe, the Americas, and the Caribbean. Existentia Africana is an engaging and highly readable introduction to the field of Africana philosophy and will help to define this rapidly growing field. Lewis R. Gordon clearly explains Africana existential thought to (...) a general audience, covering a wide range of both classic and contemporary thinkers--from Douglass and DuBois to Fanon, Davis and Zack.

Her Majesty's Children reveals not only a deeply personal account of the experience of racism but is also a revolutionary work that asks us to reconsider our ordinary practices and lives to recognize and resist the traces of a colonial age of racism that so many claim is only part of our past.

Christianity teaches that whenever evil is done, God had ample warning. He could have prevented it, but He didn't. He could have stopped it midway, but He didn't. He could have rescued the victims of the evil, but - at least in many cases - He didn't. In short, God is an accessory before, during, and after the fact to countless evil deeds, great and small. An explanation is not far to seek. The obvious hypothesis is that the Christian God (...) is really some sort of devil. Maybe He is a devil as popularly conceived, driven' by malice. Or maybe He is unintelligibly capricious. Or maybe He is a fanatical artist who cares only for the aesthetic quality of creation - perhaps the abstract beauty of getting rich variety to emerge from a few simple laws, or perhaps the concrete drama of human life with all its diversity - and cares nothing for the good of the creatures whose lives are woven into His masterpiece. Oust as a tragedian has no business providing a happy end out of compassion for his characters.) But no; for Christianity also teaches that God is morally perfect and perfectly benevolent, and that He loves all of His creatures; and that these things are true in a sense not a million miles from the sense in which we attribute morality, benevolence, or love to one another.

Inoperative Learning draws upon the movement towards a weak philosophy that is currently gaining ground in educational philosophy: this weak philosophy does not offer a set of solutions or guidelines for improving educational outcomes, but rather renders assumptions about the theory-practice coupling that is so popular in contemporary education inoperative. By arguing that such logic reduces education to merely instrumental ends, which can only be assessed in terms of predefined measurement tools, this book presents a challenge to contemporary notions of (...) education as learning. There are various forms of inoperative education that temporarily suspend the goal-directedness of learning. From the perspective of learning, the neutralization of progress, growth, and maturity would usually be seen as obstacles needing to be overcome on the path toward set goals. Yet Lewis argues that a serious investigation of inoperativity opens up possibilities that would be otherwise unavailable in a world fixated on the question of learning. In dialogue with philosophers (Agamben, Benjamin, and Esposito), as well as authors (Kafka and Walser), and qualitative researchers (Lather), Lewis turns our collective attention to what remains when concepts such as learning, child development, teacher effectivity, and personal growth are left idle. Inoperative Learning presents a radical rewriting of educational possibilities. It should therefore be of great interest to educational researchers and educational philosophers concerned with the question of alternative logics of education beyond learning. The book may also be of interest to educational policy specialists who are looking for new and innovative forms of critique and analysis. (shrink)

If we are going to treat other species so very differently from our own — killing, eating and experimenting on pigs and sheep, for example, but never human beings — then it seems we need to come up with some morally relevant difference between us and them that justifies this difference in treatment. Otherwise it appears we are guilty of bigotry (in just the same way that someone who discriminates on the basis of race or sex is guilty of bigotry). (...) But what is this morally relevant difference? Julia Tanner's article examines, and rejects, some of the most popular answers to this question. -/- . (shrink)

My office is in a medical building in suburban Washington, D.C. —in Bethesda, named for the Biblical healing pool. All of the offices of my building are occupied by medical specialists, representing the most sophisticated training in the application of the scientific method. Downstairs and of service to all of us is a pharmacy, looking for all the world like a research laboratory with its gleaming surface, meticulous cleanliness, micro-balances, records, reference books, and cash register. It is neatly stocked with (...) modern, physiologically-defined preparations of active, predictable drugs. Among the enzymes, hormones, antibiotics, and chemo therapeutics for neoplasm, are a few newly hatched, unfledged remedies, but most are dependable and thoroughly assayed. The intently busy, white-coated, unsentimental pharmacists serve a hard-headed group of practitioners and a neighborhood of upper-class, well-educated patients. It is disconcerting, then, to see the undersurface of this sophistication, the irrational shadows beneath the science. On the front counter of the pharmacy are displayed attractive colored advertisements and pleasantly seductive inducements to self-improvement through diet cults and foods, tranquilizers, energizers, protein supplements, happiness promisers, preparations to enhance sexuality, vitamins artfully combined, and many packeted stuffs of no rational or pretended use whatsoever. “Why,” I ask the gimlet-eyed pharmacist, “do you have this large display of ‘Il Wah Genuine Chinese Ginseng, the Miraculous Herb of Life’? Doesn't it violate your university training? Your integrity as a modernist?” “Oh,” says he, “ginseng makes you feel better! You have more energy. You can do more! Lots of athletes use it, and people who work too hard and feel exhausted. It's only $3.45 a package. The prescriptions you give me once in a while yield no profit, but I sell a lot of ginseng. I use it myself!” Bemused, I walk back to my office, wondering about the easy abandonment of rationality, and pull down a box of medicinals collected the year before at an open-air pharmacy in the riverside markets of Brazil. The box gives forth deliciously rich forest smells. The packets within contain barks, roots, seeds, all of purported medical value. Other packets have amulets, charms, and protectives. The colorful labels on some of the patent medicines invoke ancient saints and healers, and promise happiness, health, prosperity and power. The essential rationale for their use in indigenous medicine was illusive to me despite many conversations with indigenous healers, and many times I have gone through the hundreds of items trying to find the key to what Brazilian and North American people fundamentally want from a pharmacy. In both cultures, where does magic stop and science begin? Do shops in both countries vend talismans in the search for the enhanced life, and fetishes against death? How much of all drug use is ritual and inchoate expectation? How can we reduce the mystification and incrementally increase the rationality of our pharmacopeia? (shrink)

Background Studying global health problems requires international multidisciplinary teams. Such multidisciplinarity and multiculturalism create challenges in adhering to a set of ethical principles across different country contexts. Our group on health system responses to violence against women (VAW) included two universities in a European high-income country (HIC) and four universities in low-and middle-income countries (LMICs). This study aimed to investigate professional and policy perspectives on the types, causes of, and solutions to ethical challenges specific to the ethics approval stage of (...) the global research projects on health system responses to VAW. Methods We used the Network of Ethical Relationships model, framework method, and READ approach to analyse qualitative semi-structured interviews (n = 18) and policy documents (n = 27). In March-July 2021, we recruited a purposive sample of researchers and members of Research Ethics Committees (RECs) from the five partner countries. Interviewees signposted policies and guidelines on research ethics, including VAW. Results We developed three themes with eight subthemes summarising ethical challenges across three contextual factors. The global nature of the group contributed towards power and resource imbalance between HIC and LMICs and differing RECs’ rules. Location of the primary studies within health services highlighted differing rules between university RECs and health authorities. There were diverse conceptualisations of VAW and vulnerability of research participants between countries and limited methodological and topic expertise in some LMIC RECs. These factors threatened the timely delivery of studies and had a negative impact on researchers and their relationships with RECs and HIC funders. Most researchers felt frustrated and demotivated by the bureaucratised, uncoordinated, and lengthy approval process. Participants suggested redistributing power and resources between HICs and LMICs, involving LMIC representatives in developing funding agendas, better coordination between RECs and health authorities and capacity strengthening on ethics in VAW research. Conclusions The process of ethics approval for global research on health system responses to VAW should be more coordinated across partners, with equal power distribution between HICs and LMICs, researchers and RECs. While some of these objectives can be achieved through education for RECs and researchers, the power imbalance and differing rules should be addressed at the institutional, national, and international levels. Three of the authors were also research participants, which had potential to introduce bias into the findings. However, rigorous reflexivity practices mitigated against this. This insider perspective was also a strength, as it allowed us to access and contribute to more nuanced understandings to enhance the credibility of the findings. It also helped to mitigate against unequal power dynamics. (shrink)

A set of qubit channels has a classical representation when it is isomorphic to the convex closure of a group of classical channels. From Crowder and Martin (Proceedings of Quantum Physics and Logic, Electronic Notes in Theoretical Computer Science, 2009), we know that up to isomorphism there are five such sets, each corresponding to either a subgroup of the alternating group on four letters, or a subgroup of the symmetric group on three letters. In this paper, we show that the (...) classical representation of a qubit channel also carries its information theoretic data—in particular, both the Holevo capacity and the scope of a unital qubit channel can be completely calculated from a systematically determined classical channel.

This paper attempts to demonstrate Max Scheler’s anticipation of and continued relevance to a burgeoning trend of essence-based accounts of modality, chief among them being Kit Fine’s landmark 1994 “Essence and Modality.” I argue that Scheler’s account of the material a priori not only anticipates the picture of essence-based modality suggested by Fine, but moreover offers resources with the potential to resolve key challenges for the Finean program. In particular, Fine’s account runs into problems in explaining how formal logical necessities (...) are to be grounded in essences, challenges that put pressure on the essentialist to adopt a non-propositional account of the nature of logical principles. I argue that one such account can be found in Scheler’s notion of the material a priori, according to which all necessary propositional truth is grounded in a realm of experientially given yet a priori "phenomenological facts." After showing the general rapprochement between Scheler’s and Fine’s accounts of regional modality, I then turn to address Scheler’s attempt to ground formal logical principles in essences. On Scheler’s picture, propositions expressing formal logical truths are true in virtue of the domain of essences in two senses: In terms of what Scheler calls objective necessity, they are true insofar as they coincide with the essential facts and interconnections shared by all possible regions of being; In terms of what he calls subjective necessity, they are true in virtue of these same essential facts and interconnections insofar as they have become “functionalized” into law-like patterns of cognition.

All else being equal, can granting the objective purport of moral experience support a presumption in favor of some form of moral objectivism? Don Loeb (2007) has argued that even if we grant that moral experience appears to present us with a realm of objective moral fact—something he denies we have reason to do in the first place—the objective purport of moral experience cannot by itself provide even prima facie support for moral objectivism. In this paper, I contend against Loeb (...) that granting the objective purport of ordinary moral experience is sufficient to support a defeasible presumption in favor of moral objectivism, and this by constituting non-explanatory, comparative confirmation that incrementally raises the prima facie likelihood that moral facts exist. More specifically, I appeal to a modest confirmation principle shared by Likelihoodists and Bayesieans - namely, the Weak Law of Likelihood - in an effort to show that (i) at a minimum, moral experience establishes a middling scrutable probability for a sufficient but not necessary condition of moral objectivism being true, and that (ii) this moderate probability in turn constitutes evidence that makes it prima facie more probable than not that some form of moral objectivism is true.

If a guilty offender is justly sentenced to be punished and an innocent volunteer agrees to be punished instead, is that any reason to leave the offender unpunished? In the context of mundane criminal justice, we mostly think not. But in a religious context, some Christians do believe in penal substitution as a theory of the atonement.

Some philosophers (such as Kant and Rawls) think it is only wrong to be cruel to cats because it will make one behave cruelly to humans. This explanation is unsatisfactory. Why? Because being cruel to your cat is a direct wrong to your cat regardless of the effects it has on other humans. Ascribing the wrongness of cruelty to the fact it will make one callous to other humans is to assess the character of the cruel person not the act (...) they are performing. Cruelty to your cat is wrong because it wrongs your cat directly. (shrink)

Proponents of the argument from regress maintain that the existence of Instrumental Value is sufficient to establish the existence of Intrinsic Value. It is argued that the chain of instrumentally valuable things has to end somewhere. Namely with intrinsic value. In this paper, I shall argue something a little more modest than this. I do not want to argue that the regress argument proves that there is intrinsic value but rather that it proves that the idea of intrinsic value is (...) a necessary part of our thinking about moral value.

Some may doubt whether the question of equality of opportunity applies to women anymore. In most Western countries every career is now, in theory, open to women. Firstly, while this may be true in Western countries, it is not true in others; there are still many careers barred to women outside the West. However, affirmative action is not a remedy where women are barred from given careers, for in such cases the principle of equality of opportunity has been rejected. Rather, (...) affirmative action is a measure for achieving equality of opportunity. (shrink)
