Reviews the book, Genes, genesis, and God: Values and their origins in natural and human history by Holmes Rolston III . Drawn from a series of lectures given by the author in November of 1997 at the University of Edinburgh as part of the Gifford Lectures, this book addresses the question of whether the supremely social and human phenomena of religion and ethics can be ultimately reduced to the phenomena of biology. Challenging much of what passes for unassailable truth in (...) sociobiological and similar natural science circles, Rolston argues that religion, ethics, and science—as emergent phenomena in human culture—are not only crowning and distinctive achievements in human cultural history but that it is impossible to adequately conceive of them as having resulted from simple evolutionary or biological processes. To this end, the author argues that genetic and evolutionary processes are anything but blind, selfish, and contingent. Indeed, Rolston cogently argues that not only are our sciences of nature not value free, but nature itself is laden with values. 2012 APA, all rights reserved). (shrink)

Reviews the book, From soul to mind: The emergence of psychology, from Erasmus Darwin to William James by Edward S. Reed . Seeking to tell "a new story about the development of psychology," this lively and well-written history of psychology begins with the "realization that we do not actually know what constituted psychology in the eighteenth and nineteenth centuries" . Reed argues that because most historians of psychology devote the bulk of their attention to the work of theorists rather than (...) experimentalists, seldom examined the history and origins of ideas concerning what should and should not be counted as psychology, and pretty much refused to discuss ideas that were later proven to be mistaken, they have produced an overly narrow and fable-like picture of the early history of the discipline. In an attempt to remedy this on-going error in the historiography of psychology, Dr. Reed urges us to examine the historical, literary, and cultural context of the eighteenth and nineteenth centuries that gave birth to the development of the career of "being a psychologist." 2012 APA, all rights reserved).

Reviews the book, Neurophilosophy of free will: From libertarian illusions to a concept of natural autonomy by Henrik Walter and C. Klohr . In this book, Henrik Walter applies the methodology of neurophilosophy to one of philosophy’s central challenges and enduring questions: the notion of free will. The author argues that free will is an illusion if we mean by it that under identical conditions we would be able to do or decide otherwise, while simultaneously acting only for reasons and (...) being the true originators of our actions. In place of this problematic version of free will, Walter offers what he calls “natural autonomy,” that is, self-determination unaided by supernatural powers that could exist even in an entirely determined universe. 2012 APA, all rights reserved).

Reviews the book, The mismeasure of desire: The science, theory, and ethics of sexual orientation by Edward Stein . It would hardly be overstating the matter to say that perhaps the single most hotly debated issue in both psychology and contemporary American culture is the nature and origins of human sexual desires. In opposition to the currently more widely accepted thesis that sexual orientation is determined at birth, philosopher and educator Edward Stein argues in this new book that much of (...) what we think we know about the origins of sexual desire is probably misguided and incomplete. Carefully examining a broad range of research on sexual orientation, Stein suggests that many of the most frequently cited findings are deeply flawed—not only methodologically but also in light of certain unquestioned philosophical assumptions and cultural stereotypes. Although the arguments in Stein’s book are more than a little likely to create controversy, and, indeed, some may well be found to be specious, his book is nonetheless a very welcome infusion of thoughtful philosophical and psychological thinking into the all-too-often muddled arena of contemporary academic and political debate. 2012 APA, all rights reserved).

This work explores two lesser known aspects of Georg Lukács's thought: his conception of language and theory of science, and his achievements in literary history. This book defends Lukács's concept of rationality and presents an original argument demonstrating that there are good reasons for choosing rationalism; that is, it is possible to establish the foundations of rationalism. Internationally unknown aspects of Lukács's oeuvre are also investigated, making extensive use of a number of his untranslated writings. János Kelemen's main statement is (...) that, for the reader, the most important motif of Lukács's thought is its defense of reason. Students and scholars of philosophy, political science, literary theory, and the humanities will be interested in this book. (shrink)

The Review was founded in 1961 to bring an existential and phenomenological approach to the understanding of human experience. With a primary focus on the psychotherapeutic endeavor, the Review publishes original essays and first translations from the fields of literature and philosophy, as well as from psychology and psychiatry proper. The Review has published essays by nearly every major figure in the world, including Viktor Frankl, Eugene Gendlin, Jacques Lacan, R.D. Laing, RolloMay, Maurice Merleau-Ponty, Jacob Needleman, Carl Rogers, and Jean-Paul (...) Sartre. In addition to continuing to publish original essays on a wide variety of general topics, in recent years the Review has published a series of special issues devoted to major figures in the field of existential psychology. 2012 APA, all rights reserved).

In a famous footnote in Naming and Necessity, Kripke offered “something like a proof” of the thesis that material things have their material origins essentially (EMO). Although the sketch of a proof Kripke gave was incomplete in important respects, many philosophers have since endeavoured to develop Kripke’s style of argument so that it reaches its intended conclusion.1 In particular, a number of philosophers have attempted to complete Kripke’s argument sketch by appealing to some sort of “sufficiency principle” – a principle (...) that gives sufficient conditions for the identity of objects across possible worlds. These developments of Kripke’s argument face a number of problems, as pointed out by Mackie (1987, 2002), Robertson (1998, 2000) and others.2 Recently, however, Rohrbaugh and deRosset (2004, 2006) have offered a new route to origin essentialism that develops a Kripke-style argument without appeal to a sufficiency principle. While this argument has also not escaped criticism3, the argument suffers from a crucial flaw which has not been noticed. More interesting, though, is that the problem the argument faces is the same problem facing the arguments that appeal to sufficiency principles, and indeed Kripke’s original “proof” – all these arguments over-generalize. This strongly suggests that there is no Kripkestyle route to origin essentialism. (shrink)

We discuss the role of the notion of information in the description of physical reality. We consider theories for which dynamics is linear with respect to stochastic mixing. We point out that the no-cloning and no-deleting principles emerge in any such theory, if law of conservation of information is valid, and two copies contain more information than one copy. We then describe the quantum case from this point of view.

In the last 30 years repeated attempts have been made to develop a proof-sketch Kripke gave for essentialism about material origins into a cogent argument. I argue that there are general reasons that all such attempts have failed, and so we should likewise expect future attempts to fail.

The origin of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is the subject of many hypotheses. One of them, proposed by Segreto and Deigin, assumes artificial chimeric construction of SARS‐CoV‐2 from a backbone of RaTG13‐like CoV and receptor binding domain (RBD) of a pangolin MP789‐like CoV, followed by serial cell or animal passage. Here we show that this hypothesis relies on incorrect or weak assumptions, and does not agree with the results of comparative genomics analysis. The genetic divergence between (...) SARS‐CoV‐2 and both its proposed ancestors is too high to have accumulated in a lab, given the timeframe of several years. Furthermore, comparative analysis of S‐protein gene sequences suggests that the RBD of SARS‐CoV‐2 probably represents an ancestral non‐recombinant variant. These and other arguments significantly weaken the hypothesis of a laboratory origin for SARS‐CoV‐2, while the hypothesis of a natural origin is consistent with all available genetic and experimental data.

A new translation of one of the great koan collections--by the premier translator of the Chinese classics--that reveals it to be a literary and philosophical masterwork beyond its association with Chan/Zen. Zen is famous for its koans, those seemingly confounding statements, questions, or stories that masters use to gauge their students' practice. Here, the lauded modern master of Chinese poetry translation asks us to reimagine one of the greatest of the koan collections in a new way: as a classic of (...) Chinese philosophical literature in the tradition of the Tao Te Ching or the Chuang Tzu. He presents the No-Gate Gateway (variously also familiar to readers as the Mumonkan, Wu-men Kuan, Gateless Gate, or Gateless Barrier), in a "bare bones" version, without the usual additional commentary, not intended to be studied in the usual case-by-case method, but to be read as a complete work in itself, one that leads the reader carefully on a path to the discovery of the deep nature of reality--an unconventional way of reading it that can be truly revelatory.

Does state weakness lead to representation via taxation? A distinguished body of scholarship assumes that fiscal need forced weak states to grant rights and build institutions. The logic is traced to pre-modern Europe. However, the literature has misunderstood the link between state strength and the origins of representation. Representation emerged where the state was already strong. In pre-modern Europe, representation originally was a legal obligation, not a right. It became the organizing principle of central institutions where rulers could oblige communities (...) to send representatives authorized to commit to decisions taken at the center. Representation thus presupposed strong state capacity, especially to tax. The revision amends our understanding of the historical paradigms guiding the literature, as well as the application of these paradigms to policies in the developing world. It suggests that societal demands for accountability and better governance are more likely to emerge in response to taxation already effectively applied. (shrink)

Zen/Chan 禪 occupies a unique position in world intellectual history. This article argues that there is a trend in the development of Chan thought which significantly reduces the innovative nature of Huineng’s 慧能 original thought and evinces an institutional effort to realign Huineng’s school of Chan with the Buddhist establishment. Its main objective is to locate the original sources of Huineng’s Chan and restore the revolutionary ideas of his thought. Adopting an approach that integrates historical materials with psychology, neuroscience with (...) philosophy, and close reading of Huineng’s interpretation of the Diamond Sutra and his innovative ideas and methods of cultivation in the Platform Sutra in relation to Laozi’s 老子 and Zhuangzi’s 莊子 Daoist ideas, it works out insights into the originality and universal appeal of Chan and the hitherto unpenetrated secret of Chan enlightenment. It concludes that the core of Huineng’s Chan thought is his idea of wunian 無念 (no-thinking), and satori 悟り is not the Buddhist enlightenment. (shrink)

The causative agent of COVID‐19 SARS‐CoV‐2 has led to over 4 million deaths worldwide. Understanding the origin of this coronavirus is important for the prevention of future outbreaks. The dominant point of view that the virus transferred to humans either directly from bats or through an intermediate mammalian host has been challenged by Segreto and Deigin, who claim that the genome of SARS‐CoV‐2 has certain features suggestive of its artificial creation. Following their response to our commentary, here we continue (...) the discussion of the proposed arguments for this hypothesis. We show that neither the existence of a furin cleavage site in SARS‐CoV‐2, nor the presence of specific sequences within the nucleotide insertion encoding that site are evidence for intelligent design. We also explain why existing genetic data, viral diversity and past human history suggest that a natural origin of the virus is the most likely scenario. Genetic evidence suggesting otherwise is yet to be presented. (shrink)

In O'Regan & Noë's (O&N's) account for the phenomenal experience of seeing, awareness is equated to what is within the current focus of attention. They find no place for a distinction between phenomenal and access awareness. In doing so, they essentially present a dualistic solution to the mind-brain problem, and ignore that we do have phenomenal experience of what is outside the focus of attention.

Stuart Kauffman here presents a brilliant new paradigm for evolutionary biology, one that extends the basic concepts of Darwinian evolution to accommodate recent findings and perspectives from the fields of biology, physics, chemistry and mathematics. The book drives to the heart of the exciting debate on the origins of life and maintenance of order in complex biological systems. It focuses on the concept of self-organization: the spontaneous emergence of order widely observed throughout nature. Kauffman here argues that self-organization plays an (...) important role in the emergence of life itself and may play as fundamental a role in shaping life's subsequent evolution as does the Darwinian process of natural selection. Yet until now no systematic effort has been made to incorporate the concept of self-organization into evolutionary theory. The construction requirements which permit complex systems to adapt remain poorly understood, as is the extent to which selection itself can yield systems able to adapt more successfully. This book explores these themes. It shows how complex systems, contrary to expectations, can spontaneously exhibit stunning degrees of order, and how this order, in turn, is essential for understanding the emergence and development of life on Earth. Topics include the new biotechnology of applied molecular evolution, with its important implications for developing new drugs and vaccines; the balance between order and chaos observed in many naturally occurring systems; new insights concerning the predictive power of statistical mechanics in biology; and other major issues. Indeed, the approaches investigated here may prove to be the new center around which biologicalscience itself will evolve. The work is written for all those interested in the cutting edge of research in the life sciences. (shrink)

Is original sin compatible with evolution? Many today believe the answer is 'No'. Engaging Aquinas's revolutionary account of the doctrine, Daniel W. Houck argues that there is not necessarily a conflict between this Christian teaching and mainstream biology. He draws on neglected texts outside the Summa Theologiae to show that Aquinas focused on humanity's loss of friendship with God - not the corruption of nature. Aquinas's account is theologically attractive in its own right. Houck proposes, moreover, a new Thomist view (...) of original sin that is consonant with evolution. This account is developed in dialogue with biblical scholarship on Jewish hamartiology and salient modern thinkers, and it is systematically connected to debates over nature, grace, the desire for God, and justification. In addition, the book canvasses a number of neglected premodern approaches to original sin, including those of Anselm, Abelard, and Lombard. (shrink)

La gnose constitue un des phénomènes les plus fascinants de l’histoire des idées. Elle est apparue sous le Haut-Empire romain (Ier-IIe siècle), période brillante et inquiète, qui voit aussi l’essor du christianisme. Les gnostiques, Basilide, Valentin, Marcion, prêchent des doctrines étranges se présentant comme une connaissance secrète (gnose) que Jésus-Christ aurait transmise à ses proches. Christianisme philosophique ou sulfureuse contrefaçon? Sagesse élevée ou charlatanisme? Religion sui generis ou maladie infantile du christianisme? Ultime expression de la philosophie grecque ou anticipation de (...) l’existentialisme? Vecteur d’influences juives ou au contraire rejet du judaïsme? La gnose garde une partie de son mystère. Née en Orient (Syrie, Egypte), répandue à Rome, dénoncée par les Pères de l’Eglise (saint Irénée, Tertullien), elle connaît peut-être son sommet aux confins de l’Empire perse avec Mani (IIIe siècle) dont la doctrine, le manichéisme, se répand jusqu’en Chine et pourrait avoir inspiré le bouddhisme. Depuis la fin des cathares (XIVe siècle), dernier avatar de la gnose européenne, celle-ci se survit par des traditions initiatiques (franc-maçonnerie, théosophie), des lignées de maîtres spirituels qui s’en réclament et des influences diffuses sur la littérature, particulièrement romantique, la musique, la philosophie. Par son rejet radical du monde réel ou sa volonté d’émanciper l’esprit des contraintes de la condition charnelle, le mode de pensée gnostique imprègne à bien des égards la culture contemporaine. Sur un sujet complexe et controversé, l’auteur présente, dans une perspective historique, une synthèse claire, vivante et équilibrée. (shrink)

Perhaps no one has written more extensively, more deeply, and more insightfully about determinism and freedom than Ted Honderich. His influence and legacy with regard to the problem of free will—or the determinism problem, as he prefers to frame it—looms large. In these comments I would like to focus on three main aspects of Honderich ’s work: his defense of determinism and its consequences for origination and moral responsibility; his concern that the truth of determinism threatens and restricts, but does (...) not eliminate, our life-hopes; and his attack on the traditional justifications for punishment. In many ways, I see my own defense of free will skepticism as the natural successor to Honderich ’s work. There are, however, some small differences between us. My goal in this paper is to clarify our areas of agreement and disagreement and to acknowledge my enormous debt to Ted. If I can also move him toward my own more optimistic brand of free will skepticism that would be great too. (shrink)

Origin of the German Trauerspiel was Walter Benjamin's first full, historically oriented analysis of modernity. Readers of English know it as "The Origin of German Tragic Drama," but in fact the subject is something else--the play of mourning. Howard Eiland's completely new English translation, the first since 1977, is closer to the German text and more consistent with Benjamin's philosophical idiom. Focusing on the extravagant seventeenth-century theatrical genre of the trauerspiel, precursor of the opera, Benjamin identifies allegory as (...) the constitutive trope of the Baroque and of modernity itself. Allegorical perception bespeaks a world of mutability and equivocation, a melancholy sense of eternal transience without access to the transcendentals of the medieval mystery plays--though no less haunted and bedeviled. History as trauerspiel is the condition as well as subject of modern allegory in its inscription of the abyssal. Benjamin's investigation of the trauerspiel includes German texts and late Renaissance European drama such as Hamlet and Calderón's Life Is a Dream. The prologue is one of his most important and difficult pieces of writing. It lays out his method of indirection and his idea of the "constellation" as a key means of grasping the world, making dynamic unities out of the myriad bits of daily life. Thoroughly annotated with a philological and historical introduction and other explanatory and supplementary material, this rigorous and elegant new translation brings fresh understanding to a cardinal work by one of the twentieth century's greatest literary critics.--.

"Exemplary Originality": Kant on Genius and Imitation MARTIN GAMMON 1. INTRODUCTION ACCORDING TO ERNST CASSIRER, Kant 's discussion of genius in the Third Cri- tique stands "at the crossroads of all aesthetic discussions in the eighteenth century," in that he tries to accommodate the neo-Classical demand that art- works follow determinate rules to the Romantic insistence that aesthetic cre- ativity be free from such rules? In the Third Critique itself, Kant defends both of these criteria through the doctrine of "exemplary (...) originality." For Kant, the genius combines two qualities: on the one hand, "a talent for produc- ing that for which no rule can be given," so that "originality must be its primary property"; however, "since there may also be original nonsense, its products must at the same time be models, i.e., be exemplary; and consequently, though not themselves derived from imitation, they must serve that purpose for oth- ers, i.e., as a standard or rule for estimating."' On the basis of this exemplary originality, then, a genius puts "freedom from constraint of rules so into force in his art, that for art itself a new rule is won -- which is what shows a talent to be exemplary". Recently, some commentators have puzzled over the "air of paradox" sur- rounding Kant 's union of originality and exemplarity in works of genius. "If such works," Timothy Gould conjectures, "make advances on what is familiar and gain new ground, their very. (shrink)

La vie est-elle un phénomène émergent ? Traduit-elle l'apparition de propriétés nouvelles au niveau d'un tout, qui seraient irréductibles aux propriétés et à l'organisation des composants de ce tout, ou encore imprédictibles à partir de ces mêmes éléments ? Développées à la charnière des XIXe et XXe siècles comme alternative aux deux approches antinomiques du vivant que sont le vitalisme et le mécanisme, la notion philosophique d'émergence connait aujourd'hui de nouveaux développements : avec la prise de conscience de la complexité (...) du vivant, un nouveau discours émergentiste refait surface en biologie et dans le champ scientifique des origines de la vie. Que signifie la notion d'émergence lorsqu'elle s'applique à l'apparition de la vie sur Terre ? Quelles sont sa pertinence et sa portée ? Dans ce livre, Christophe Malaterre propose une clarification conceptuelle de la notion philosophique d'émergence ; il en défend une conception epistémique et contextuelle, adossée à la notion d'explication. En s'inspirant des travaux les plus contemporains sur les origines de la vie, il montre que, selon le contexte epistémique dans lequel le phénomène est évalué, la qualification de l'apparition de la vie comme émergente est, ou non, justifié. Il défend alors la thèse selon laquelle la caractérisation émergentiste de l'apparition de la vie n'est qu'une conséquence temporaire des limites de nos connaissances scientifiques. (shrink)

Ambitious and elegant, this book builds a bridge between evolutionary theory and cultural psychology. Michael Tomasello is one of the very few people to have done systematic research on the cognitive capacities of both nonhuman primates and human children. The Cultural Origins of Human Cognition identifies what the differences are, and suggests where they might have come from. -/- Tomasello argues that the roots of the human capacity for symbol-based culture, and the kind of psychological development that takes place within (...) it, are based in a cluster of uniquely human cognitive capacities that emerge early in human ontogeny. These include capacities for sharing attention with other persons; for understanding that others have intentions of their own; and for imitating, not just what someone else does, but what someone else has intended to do. In his discussions of language, symbolic representation, and cognitive development, Tomasello describes with authority and ingenuity the "ratchet effect" of these capacities working over evolutionary and historical time to create the kind of cultural artifacts and settings within which each new generation of children develops. He also proposes a novel hypothesis, based on processes of social cognition and cultural evolution, about what makes the cognitive representations of humans different from those of other primates. -/- Lucid, erudite, and passionate, The Cultural Origins of Human Cognition will be essential reading for developmental psychology, animal behavior, and cultural psychology.

This book proposes a new theory of the origins of human language ability and presents an original account of the early evolution of language. It explains why humans are the only language-using animals, challenges the assumption that language is a consequence of intelligence, and offers a new perspective on human uniqueness. The author draws on evidence from archaeology, linguistics, cognitive science, and evolutionary biology. Making no assumptions about the reader's prior knowledge he first provides an introductory but critical survey of (...) all sources of evidence for language evolution. He then considers what language itself reveals about its own and human origins and evolution. He shows that certain central aspects of language do not, unexpectedly, reflect what they are used for, are maladapted for their function. He considers why this should be, and argues that these odd aspects of language reveal important clues about its evolutionary origin. The Origins of Complex Language fulfils the promise of its title. In doing so it turns upside down conventional theories about the relation between cognition and expression, truth and reference, and the co-evolution of mind and body. Original in conception, brilliantly executed, stylishly written, this book will attract a wide range of readers interested in the evolution and origins of language. (shrink)

I here defend historical entitlement theories of property rights against a popular charge. This is the objection that such theories fail because no convincing account of original appropriation exists. I argue that this argument assumes a certain reading of historical entitlement theory and I spell out an alternative reading against which it misfires. On this reading, the role of acts of original appropriation is not to justify but to individuate people’s holdings. I argue that we can identify which acts count (...) as original appropriation against the background of a general justification for a practice of property rights. On this view, what I will call ‘natural’ acts of original appropriation are acts by which a person begins to satisfy the general conditions for justified ownership. Finally, I offer an interpretation of John Locke's theory of appropriation along these lines and argue that it provides an attractive reading of his view. (shrink)

In this article, I advance what I think is a more theologically robust and informed free-will defense, which allows me to address the problem of evil in a more theologically robust and informed way. In doing so, however, I do not claim to offer a comprehensive response to the problem of evil, or full-blown "theodicy"; instead, I offer a partial response, which I place in the service of a full-blown theodicy. Moreover, my own approach is explicitly Thomistic, insofar as I (...) formulate much of it drawing on Thomas Aquinas's own formulations of the doctrines of original justice and original sin, or the human being as created and fallen. Structurally, the article consists of three main sections. In first section, I consider and critique a recent, expanded free-will defense offered by Peter van Inwagen, which also incorporates the doctrines of creation and the Fall. I then introduce key aspects of Aquinas's own thought in order to make the requisite improvements to this approach. In the second section of the article, I consider some main objections to my own Thomistic approach, as I will have formulated it so far: in particular, that the doctrines of original justice and original sin are unintelligible from the standpoints of moral psychology and evolutionary biology. I also begin to consider the objection that there is no intelligible way of explaining the transmission of original sin. In the third and final section of the article, I respond to these objections, offering a final defense of my central claim that the free-will defense is best served when it is wedded with a specifically Thomistic construal of the human being as originally created in a state of original justice, but now subject to defects (both bodily and spiritual) that are the inherited consequences of original sin.

Many of the features that distinguish the vertebrates from other chordates are derived from the neural crest, and it has long been argued that the emergence of this multipotent embryonic population was a key innovation underpinning vertebrate evolution. More recently, however, a number of studies have suggested that the evolution of the neural crest was less sudden than previously believed. This has exposed the fact that neural crest, as evidenced by its repertoire of derivative cell types, has evolved through vertebrate (...) evolution. In this light, attempts to derive a typological definition of neural crest, in terms of molecular signatures or networks, are unfounded. We propose a less restrictive, embryological definition of this cell type that facilitates, rather than precludes, investigating the evolution of neural crest. While the evolutionary origin of neural crest has attracted much attention, its subsequent evolution has received almost no attention and yet it is more readily open to experimental investigation and has greater relevance to understanding vertebrate evolution. Finally, we provide a brief outline of how the evolutionary emergence of neural crest potentiality may have proceeded, and how it may be investigated.

One of the most unpredictable things the pandemic brought to our societies was the closure of hospitals and other health services to visitors. Preventing the spread of infection was the main reason for these decisions in the early days of the pandemic when there was no clarity about the means of transmission and the origin of the virus. However, in view of the persistence of the restrictions to date and the numerous negative consequences they have had on the professional (...) and personal quality of life of doctors, nurses, patients and carers, the aim of this article is to analyse in depth the reasons why these decisions have been and, above all, are still being applied, also considering the hypothesis that the choices made so far in the training of health professionals should be questioned. The persistence of restrictions, the constant reduction of human and economic resources in the face of an increase in the demand for care have exacerbated the distance between health professionals and users, to the point of escalating into actual acts of violence and aggression. According to the Critical Pedagogy approach, educators can play a central role in activating formative and collaborative strategies, such as maieutic groups, to rebuild an alliance between those who today find themselves on opposite sides: health professionals on the one hand, and patients and families on the other.
