This article asks whether enhancement can truly lead to something beyond humanity, or whether it is, itself, an inherently human act. The ‘posthuman’ is an uncertain proposition. What, exactly, would one be? Many commentators suggest it to be an endpoint for the use of enhancement technologies, yet few choose to codify the term outright; which frequently leads to unnecessary confusion. Characterizing and contextualizing the term, particularly its more novel uses, is therefore a valuable enterprise. The abuse of the term ‘Human’, (...) especially in the context of the enhancement debate and the myriad meanings ascribed to it, could give ‘posthuman’ very different slants depending on one's assumptions. There are perhaps three main senses in which the term ‘human’ is employed: the biological, the moral, and the self-idealizing. In the first of these, ‘human’ is often conflated with Homo sapiens, and used interchangeably to denote species; in the second, ‘human’ generally refers to a community of beings which qualify as having a certain moral value; and the third, the self-idealizing sense, is more descriptive; a label denoting the qualities that make us who we are as beings, or ‘what matters about those who matter’. So, what might enhancement make us? A novel species or genus of hominid? Or, perhaps, a morally more valuable being than a regular human? Of course, there's a third option: that a posthuman is a being which embodies our self-ideal more successfully than we do ourselves – one ‘more human than human’. Which to choose? (shrink)

Toward A Sociological Imagination builds on the ideas C. Wright Mills expressed in The Sociological Imagination for an approach to the scientific method broad enough to open up to the full range of knowledge within the sociology discipline. In this book, nine sociologists and one philosopher provide detailed tests of the utility of the approach within diverse substantive sociological areas.

Objectives—To evaluate a departmental computer system.Design—a. Direct comparison of the time taken to use a manual system with the time taken to use a computer system for lung function evaluation, loan of equipment and production of correspondence. b. Analysis of the accuracy of data capture before and after the introduction of the computer system. c. Analysis of the comparative running costs of the manual and computer systems.Setting—Within a department of respiratory medicine serving a hospital of 1323 beds.Main Outcome Measures—a. Time (...) taken to perform functions with the assistance of computerised methods, in comparison to the manual method used alone. b. Accuracy of data capture. c. Relative running costs.Results—a. The computer system (CS) was significantly faster than the manual system (MS) for lung function evaluation (CS=7.63 min/test, MS=12.25 min/test), loan of equipment (CS=0.40 min/loan, MS=2.07 min/loan), and checking for overdue equipment (CS=0.49 s/record, MS=9 s/record). The production of correspondence was slightly slower with the computer (CS=9.30 min/letter, MS=8.54 min/letter). b. All outpatient episodes, but only 43 of 65 (66%) of inpatient episodes, were captured. Lung function and managerial report data were accurate using both manual and computerised methods. The manual system for equipment loans was inefficient, and use of the computer resulted in the recovery of 221 nebulisers. c. Development costs for 1988–1990 were high (£72 178). Only £1200 to £1845 per year was recovered directly from staff time saved by the computer but larger savings resulted from changes in work practice (£4049–4765). After 10 years the projected deficit is £10 000 per annum in running costs.Conclusions—In comparison with the manual methods, the computer system has shown significant advantages which provide accurate information, with significant favourable effects on working practices. In evaluating computer systems used in clinical practice it is essential to ensure that the projected work practice benefits are achieved without unacceptable costs in staff time, inaccurate data and high financial outlay.

In lieu of an abstract, here is a brief excerpt of the content:Why Buddhism and the Modern World Need Each Other:A Buddhist PerspectiveDavid R. LoyThe mercy of the West has been social revolution. The mercy of the East has been individual insight into the basic self/void. We need both.—Gary Snyder1Another way to make Snyder’s point would be: The highest ideal of the Western tradition has been the concern to restructure our societies so that they are more socially just. The most (...) important goal for Buddhism is to awaken and (to use the Zen phrase) realize one’s true nature, which puts an end to dukkha—especially that associated with the delusion of a separate self. Today it has become more obvious that we need both, not just because these ideals complement each other, but because each project needs the other.As far as I have been able to determine, the Western conception of justice largely originates with the Abrahamic traditions, particularly the Hebrew prophets, who fulminated against oppressive rulers for afflicting the poor and powerless. Describing Old Testament prophecy, Walter Kaufmann writes that “no other sacred scripture contains books that speak out against social injustice as eloquently, unequivocally, and sensitively as the books of Moses and some of the prophets.”2 Is there a Buddhist equivalent? The doctrine of karma understands something like justice as an impersonal moral law built into the fabric of the cosmos, but historically karma has functioned differently. Combined with the doctrine of rebirth (a necessary corollary, since evil people sometimes prosper in this life) and the belief that each of us is now experiencing the consequences of actions in previous lifetimes, the implication seems to be that we do not need to be concerned about pursuing justice, because sooner or later everyone gets what they deserve. In practice, this has often encouraged passivity and acceptance of one’s situation, rather than a commitment to promote social justice.Does the Buddhist emphasis on dukkha (suffering in the broad sense) provide a better parallel with the Western conception of justice? Dukkha is arguably its most important concept: According to the Pali Canon, Sakyamuni Buddha said that what [End Page 39] he had to teach was dukkha and how to end it. Historically, Asian Buddhism has focused on individual dukkha and personal karma, a limitation that may have been necessary in autocratic polities that could and sometimes did repress Buddhist institutions. Today, however, the globalization of democracy, human rights, and freedom of speech opens the door to new ways of responding to social and institutional causes of dukkha.On the other side, the Abrahamic emphasis on justice, in combination with the Greek realization that society can be restructured, has resulted in our modern concern to pursue social justice by reforming political and economic institutions. This has involved, most obviously, various human rights movements (the abolition of slavery, the civil rights movement, feminism, LGBT liberation, etc.), which have not been an important concern of traditional Asian Buddhism. As valuable as these reforms have been, the limitations of such a institutional approach, by itself, are becoming evident. Even the best possible economic and political system cannot be expected to function well if the people within that system are motivated by greed, aggression, and delusion—the “three fires” or “three poisons” that Buddhism identifies as unwholesome motivations that need to be transformed into their more positive counterparts: generosity, loving-kindness, and wisdom.Today, in our globalizing world, the traditional Western focus on social transformation encounters the traditional Buddhist focus on individual awakening. This essay addresses why they need each other in order to actualize their own ideals and uses the example of our present economic situation to explore some of the implications of this interdependence.good versus evilThe difference in focus can be traced back to different paradigms. One way to draw the contrast between the Abrahamic and Buddhist traditions is to consider their dissimilar attitudes toward morality. The Abrahamic religions are (the primary) examples of “ethical monotheism” because they emphasize most of all ethical behavior. God’s main way of relating to us, his creatures, is instructing us how to live by giving us moral commandments. To be a good Jew, Christian, or... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 151-154 [Access article in PDF] Book Review The Happiness Project: Transforming the Three Poisons that Cause the Suffering We Inflict on Ourselves and Others The Happiness Project: Transforming the Three Poisons that Cause the Suffering We Inflict on Ourselves and Others. By Ron Leifer, M.D. Ithaca, New York: Snow Lion, 1997.313 pp. This book focuses mostly on Buddhism and psychotherapy, but it ranges widely and (...) includes many reflections on Christianity. Today there are many good books that compare Buddhism with Western psychology, but this one is not to be missed by anyone interested in the topic. Leifer (a former colleague and friend of Ernest Becker, who wrote TheDenial ofDeath) is obviously a very experienced psychiatrist, with deep knowledge of psychoanalytic theory to supplement his many years of practice [End Page 151] as a therapist. This book is many things: a primer on demythologized Buddhism; a superior "self-help" book; a history of psychotherapy, including a critique of its modern medicalization; a speculative account of the evolution of human consciousness; and, not least, the most insightful interpretations of the Job, Oedipus, and Eden myths that I have encountered. The prose style is lucid, and only space limitations keep me from quoting it at length.The title turns out to be ironic, since our Happiness Projects are the main source of our unhappiness. Our selfish strivings for happiness are, paradoxically, the main cause of the suffering we inflict on ourselves and others.What we "fail to see" (avidya)is not some great mysterious wisdom. "The core of the esoteric knowledge we seek consists of secrets we hide from ourselves. We hide from them because they are not what we want them to be. The world is not what we want it to be. Life is not what we want it to be. Others are not what we want them to be. We are not ourselves what we want to be. We hide from these truths because they mystify and terrify us" (12). The basic "secret" of happiness is that the three poisons--greed, ill will, and ignorance--are the source of our pain and suffering, by creating rebounding karmic ripples. The ego is a trickster who is continually the victim of his own trickery. True happiness can only be the product of an inner transformation that changes our habitual patterns of thought and action, enabling us to "relax into existence." Leifer's psychologized Buddhism is a therapeutic path cleansed of the mystical and paranormal; there is no place here for psychic powers or any transcendental salvation (nirvana is not discussed). The focus throughout is on how we are bedeviled by our own desires.The book is organized into four main parts. The first offers Leifer's understanding of the first two Buddhist truths. The second part, "Western Views of Suffering," includes profound interpretations of Job and Oedipus Rex. Job's suffering illustrates the first truth, that life is suffering, and his patience is virtuous, even heroic, in its refusal to demand that life be different than it is--an endurance that allows him to avoid making life worse: "Patience is the willingness to suffer without aggression" (131).The key to the Oedipus story is in his answer to the Sphinx's riddle: humans are the creatures who walk on four legs as infants, on two legs as mature adults, and then on three legs (with a cane) in old age. The riddle is a metaphor for the truths of our impermanence, old age and death. But Oedipus cannot accept it. "From a Buddhist point of view, the story of Oedipus is a metaphor for neurotic mind. Oedipus was the victim of his own grasping ego--of his desires and aggressions. His fate was sealed by his own efforts to escape it. The source of Oedipus' pain and tragedy were his own ignorance, passion, and aggression: the three poisons" (135). His desire for Mom is better understood as a symbol of human desire generally: our refusal to grow up... (shrink)

Both experimental and ethnographic studies show that reciprocal exchanges (in which actors unilaterally provide benefits to each other without formal agreements) produce stronger trust than negotiated exchanges secured by binding agreements. We develop the theoretical role of risk and uncertainty as causal mechanisms that potentially explain these results, and then test their effects in two laboratory experiments that vary risk and uncertainty within negotiated and reciprocal forms of exchange. We increase risk in negotiated exchanges by making agreements nonbinding and decrease (...) uncertainty in reciprocal exchanges by having actors communicate their intentions. Our findings support three main theoretical conclusions. (1) Increasing risk in negotiated exchange produces levels of trust comparable to those in reciprocal exchange only if the partner's trustworthiness is near-absolute. (2) Decreasing uncertainty in reciprocal exchange either increases or decreases trust, depending on network structure. (3) Even when reciprocal and negotiated exchanges produce comparable levels of trust, their trust differs in kind, with reciprocal exchange partners developing trust that is more resilient and affect-based.

In Colour for Architecture, published in 1976, the editors, Tom Porter and Byron Mikellides, explain that their book was “produced out of an awareness that colour, as a basic and vital force, is lacking from the built environment and that our knowledge of it is isolated and limited.”1 Lack of urban color was then especially salient in Britain—where the book was published—which had just begun to recoil at the Brutalist legacy of angular stained gray concrete strewn across the postwar landscape. (...) Perhaps because the most urgent need was to inject some hue into this architectural dystopia, one of the main innovations illustrated in the book involves nothing more than cans of paint. Dull unfinished concrete façades, the interior of a subway station, a cement works, and so on, are shown enlivened by fields of bright color. (shrink)

Two main uses of categories are classification and feature inference, and category labels have been widely shown to play a dominant role in feature inference. However, the nature of this influence remains unclear, and we evaluate two contrasting hypotheses formalized as mathematical models: the label special-mechanism hypothesis and the label super-salience hypothesis. The special-mechanism hypothesis is that category labels, unlike other features, trigger inference decision making in reference to the category prototypes. This results in a tendency for prototype-compatible inferences because (...) the labels trigger a special mechanism rather than because of any influences they have on similarity evaluation. The super-salience hypothesis assumes that the large label influence is due to their high salience and corresponding impact on similarity without any need for a special mechanism. Application of the two models to a feature inference task based on a family resemblance category structure yields strong support for the label super-salience hypothesis and in particular does not support the need for a special mechanism based on prototypes.

Social and cultural contexts influence power dynamics and shape gender perceptions, roles, and decisions regarding the management of agrobiodiversity for dealing with and adapting to climate change. Based on a feminist political ecology framework and a mixed method approach, this research performs an empirical analysis of two case studies in the northern of India, one in the Himalayan Mountains and another in the Indian-Gangetic plains. It explores context-specific influence of gender roles and responsibilities on on-farm agrobiodiversity management gendered expertise and (...) knowledge related to agrobiodiversity and gendered preferences for practices and institutional arrangements for agrobiodiversity conservation linked to adaptation to climate change. In the Himalayan mountains women actively participate in crop and seed management decisions and tasks, and maintain informal institutions for seed and services exchanges in the case of crisis, which simultaneously favours high levels of agrobiodiversity and enhances women’s social status. By contrast, in the Indio-Gangetic plains, where women from better-off households are socially secluded and women from poorer households work mainly as labourer to respond to high out-migration of men, they exercise less public control over agrobiodiversity, with their role being mainly invisible at the homestead and related to post-production tasks. We finally discuss as improved understanding of the links between gendered spaces, crops, tasks, social status, and agrobiodiversity management can facilitate the design of gender-sensitive policy interventions for conservation and adaptation to climate change.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

Scientific authorship serves to identify and acknowledge individuals who “contribute significantly” to published research. However, specific authorship norms and practices often differ within and across disciplines, labs, and cultures. As a consequence, authorship disagreements are commonplace in team research. This study aims to better understand the prevalence of authorship disagreements, those factors that may lead to disagreements, as well as the extent and nature of resulting misbehavior. Methods include an international online survey of researchers who had published from 2011 to (...) 2015. Of the 6673 who completed the main questions pertaining to authorship disagreement and misbehavior, nearly half reported disagreements regarding authorship naming; and discipline, rank, and gender had significant effects on disagreement rates. Paradoxically, researchers in multidisciplinary teams that typically reflect a range of norms and values, were less likely to have faced disagreements regarding authorship. Respondents reported having witnessed a wide range of misbehavior including: instances of hostility, undermining of a colleague’s work during meetings/talks, cutting corners on research, sabotaging a colleague’s research, or producing fraudulent work to be more competitive. These findings suggest that authorship disputes may contribute to an unhealthy competitive dynamic that can undermine researchers’ wellbeing, team cohesion, and scientific integrity. (shrink)

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the most effective activity (...) for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

Authorship is commonly used as the basis for the measurement of research productivity. It influences career progression and rewards, making it a valued commodity in a competitive scientific environment. To better understand authorship practices amongst collaborative teams, this study surveyed authors on collaborative journal articles published between 2011 and 2015. Of the 8364 respondents, 1408 responded to the final open-ended question, which solicited additional comments or remarks regarding the fair distribution of authorship in research teams. This paper presents the analysis (...) of these comments, categorized into four main themes: disagreements, questionable behavior, external influences regarding authorship, and values promoted by researchers. Results suggest that some respondents find ways to effectively manage disagreements in a collegial fashion. Conversely, others explain how distribution of authorship can become a “blood sport” or a “horror story” which can negatively affect researchers’ wellbeing, scientific productivity and integrity. Researchers fear authorship discussions and often try to avoid openly discussing the situation which can strain team interactions. Unethical conduct is more likely to result from deceit, favoritism, and questionable mentorship and may become more egregious when there is constant bullying and discrimination. Although values of collegiality, transparency and fairness were promoted by researchers, rank and need for success often overpowered ethical decision-making. This research provides new insight into contextual specificities related to fair authorship distribution that can be instrumental in developing applicable training tools to identify, prevent, and mitigate authorship disagreement.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This study aimed to explore the role of two models of well-being in the prediction of psychological distress during the COVID-19 pandemic, namely PERMA and mature happiness. According to PERMA, well-being is mainly composed of five elements: positive emotions, engagement, relationships, meaning in life, and achievement. Instead, mature happiness is understood as a positive mental state characterized by inner harmony, calmness, acceptance, contentment, and satisfaction with life. Rooted in existential positive psychology, this harmony-based happiness represents the result of living in (...) balance between positive and negative aspects of one's life. We hypothesized that mature happiness would be a more prominent protective factor during the present pandemic than the PERMA composite. A total of 12,203 participants from 30 countries responded to an online survey including the Depression Anxiety Stress Scale (DASS-21), the PERMA-Profiler, and the Mature Happiness Scale-Revised (MHS-R). Confirmatory factor analyses indicated that PERMA and mature happiness were highly correlated, but nonetheless, they represented two separate factors. After controlling for demographic factors and country-level variables, both PERMA Well-being and MHS-R were negative predictors of psychological distress. Mature happiness was a better predictor of stress, anxiety, and general distress, while PERMA showed a higher prediction of depression. Mature happiness moderated the relation between the perceived noxious effects of the pandemic and all markers of distress (depression, anxiety, stress, and total DASS-21). Instead, PERMA acted as a moderator in the case of depression and stress. These findings indicate that inner harmony, according to the mature happiness theory, is an essential facet of well-being to be taken into consideration. The results of this study can also orient policies aimed to alleviate the negative effects of the pandemic on mental health through the promotion of well-being. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:War, Peace, and Reconciliation: A Theological Inquiry by Theodore R. WeberDavid H. MessnerWar, Peace, and Reconciliation: A Theological Inquiry Theodore R. Weber EUGENE, OR: WIPF & STOCK, 2015. 182 pp. $23.00Weber's book makes a helpful contribution to enlivening more theologically grounded strategies for peacemaking through reconciliation. It is a careful, systematic work that takes as its foundation a distinctively Christian view of [End Page 214] God's nature and (...) relation to the world. As a scholar and a pastor for over fifty years, Weber brings a much-needed, wise, and re-centered view to the questions entangled in war, peace, and reconciliation. He advises us not to look first into the realities of war for God, but to look to understand God as the context for all human conflict. He forcefully calls the reader to be a reconciler despite the intractability of conflict. The book is structured in three main parts, beginning with the theological context, then the political context, and, last, to peace, justice, and the church.The "war" that Weber addresses is interstate conflict, representing the negation of the web of relationships constituting a healthy international system. War disrupts God's plan and ruptures the right relationship between humanity and God (43–44). Throughout, Weber embraces a kind of Christian Realism, one that takes seriously the loving nature of God, the sinfulness of humanity, and the limits and possibilities for peacemaking in a human world. Downplaying the pacifistic message of Jesus, Weber highlights the necessities within a fallen world. We cannot eliminate war as a category of existence under the conditions of sin (until the eschaton), but with right orientation and action we can eliminate some war.Noting inadequacies of the just war tradition (though not dispensing with it), Weber identifies the need to ground it more firmly in theology, including enhanced attention to "just intention" as a primary criterion in evaluating the prosecution of war, displacing cause as the first question with which we must interrogate ourselves. Discernment about war and peace must be an ongoing conversation that should include people of faith as well as policymakers. Weber's theological and pastoral sensibilities, alongside his political savvy throughout, make the book a pleasurable and provocative read.The definition of reconciliation deployed is broad and complex, and Weber marshals it for powerful work. Reconciliation "is God's work—the movement of Divine grace through history, engaging all aspects of brokenness and promise and reaching its climax of fulfillment and disclosure in the life, death, and resurrection of Jesus Christ" (3). Grace continually calls humanity to enter into the work of reconciliation. Here Weber introduces the idea of relational power; more nuanced than mere substantive power, it connects to the core idea of institution building and the critical emphasis on strengthening the social fabric in the interest of peace. It is the hallmark of the reconciling transformation from systems of dominance to relationships of consent.The book raises questions regarding how to put reconciliation as described into concrete practice, responding to real cases and controversies. Also, there could be added discussion, against this theological backdrop, of what opportunities exist amid current US and global regime change to enter this reconciling activity more fully.Ultimately, the Christian context is central to understanding the ethics that Weber advances. Weber recommends a biblical foundation, one in which [End Page 215] we take the benefit of reading scripture backward from the Christ event. Such an exegetical strategy reveals that God has a plan for all of humanity, a vision of inclusiveness and reconciliation. It is from this vantage point of God's culminating vision, Weber illuminates, that we can understand and embrace human action throughout history and the meaningful, if incomplete, work of reconciliation to which we must commit ourselves, both politically and spiritually.

Organisational Ethics could be more effectively taught if organisational agency could be better distinguished from activity in other group entities, and defended against criticisms. Some criticisms come from the side of what is called “methodological individualism”. These critics argue that, strictly speaking, only individuals really exist and act, and organisations are not individuals, real things, or agents. Other criticisms come from fear of the possible use of alleged “corporate personhood” to argue for a possible radical expansion of corporate rights e.g. (...) to claim a right to vote. Others say that if corporate businesses were persons, and judged as such, they would be sociopaths (Bakan 2004). Large corporate businesses are one kind of organisation, and if organisations were allowed to claim to be full persons, this would mean that the latter criticisms were valid. The proposed account goes between the horns of the above dilemma: impersonal aggregates or full persons. It avoids both the reductive individualism and expansive, full personhood account. It gives grounds for attributing and distributing praise and blame to organisations as whole complex entities, and to their parts. Primarily, responsibility belongs to Board incumbents within them, on the basis of their goals; their direction of the acts of the other main internal role incumbents, managers and staff, and enablers, in the role structure; their own ethical decision methods; the impact of their acts on external stakeholders like end-users, other players in the practice or local community, and on the state. These factors are picked out on the basis of a theory of meaning Aristotle’s theory of analogy of attribution, some architectonic features of his Philosophical Anthropology; and Neo-Aristotelian Virtue Ethics (NAVE). The paper expounds a quasi-person model of organisations, (QPM), previously described in this journal (Ardagh 2011, 2012, 2013). This model identifies functional similarities at three levels, between capacities within natural persons (NPs) on the one hand and the roles/ incumbents within the structure of organisational artificial/quasi-persons (APs on the other). In each entity, we find an architectonic direction, sub-ordered operational entities, and enablers (a DOE structure) in a communicative structure or reporting chain of authority. The common elements between natural persons (NP) and artificial persons (AP) and their ethically relevant attributes are captured in an acronym –GRAEOS. Both persons and organisations have a “top” entity capable of having/choosing worthwhile ethically permissible goals, G; of architectonically directing the use of capacities/repertoires or incumbents in designed architectonic roles, R, within a DOE-type structure, well or badly; of using ethical decision making procedures, E; of execution of good choices for the person or organisation in action, A, with good or bad impacts on others, or with others, O, in the context practice or domain; and of having good relations with the law and the state, S. Application to the 1989 Exxon Valdez disaster, and public sector organisations, is briefly discussed to illustrate the potential to deal with short or long case study narratives. (shrink)

John R. Searle’s 1995 publication The Construction of Social Reality is the foundation of this collection of scholarly papers examining Searle's philosophical theories. Searle’s book sets out to reconstruct the ontology of the social sciences through an analysis of linguistic practices in the context of his celebrated work on intentionality. His book provided a stimulating account of institutional facts such as money and marriage and how they are created and replicated in everyday social life. The authors in this collection provide (...) a critical appraisal of these and other ideas presented in Searle’s original publication. The editors' introduction clearly outlines the main issues in the debate and provides a useful introduction to Searle's contributions to social science. (shrink)

Opening Democracy in Contemporary Confucian Philosophy, David Elstein identifies himself, correctly, to be filling a gap in English-language scholarship. That gap, as the title partly suggests, is a lack of Anglophone accounts of contemporary Sinophone Confucian views of democracy. We have in English a robust discussion of the relationship between Confucianism and democracy, but there is very little connection between that discourse and the same discussion occurring amongst scholars in Chinese. Thus one of the main aims here is to (...) communicate the Sinophone discussion to readers otherwise cut off from it, and to evaluate its arguments.Elstein selects six thinkers from Taiwan and Mainland China for his...

The symbolism introduced earlier provides a convenient vehicle for examining the status and consistency of Aristotle's three diverse justifications and for explaining how he means to avoid Protagorean relativism without embracing Platonic absolutism. When the variables ‘ x ’ and ‘ y ’ are allowed to range over the groups of free men in a given polis as well as over individual free men, the formula for the Aristotelian conception of justice expresses the major premiss of Aristotle's three justifications: (1) (...) (∀ x )(∀ y ) (P(x)·W(x)/P(y)·W(y)=V(T(x))/V(T(y)))Democracy is justified by adding a minor premiss to the effect that as a group the many ( m ) are superior (>) in virtue and wealth to the few best men ( f ): 85 (2 d ) (P(m) · W(m)) > (P(f) · W(f)) (3 d ) V(T(m))>V(T(f))Absolute kingship is justified when a godlike man ( g ) appears in a polis who is incommensurably superior (≫) in virtue and wealth to all the remaining free men ( r ): (2 k ) (P(g) · W(g)) ≫ (P(r) · W(r)) (3 k ) V(T(g)) ≫ V(T(r))True aristocracy requires a more complex justification, which was symbolized in Section 4. These justifications are compatible with each other since they apply to different situations. The polises where democracy and true aristocracy are justified contain no godlike men, and the polis in which democracy is justified differs from that in which true aristocracy is justified in containing a large group of free men who individually have little virtue ( Pol. III.11.1281b23-25, 1282a25-26). Each of the justifications is a valid deductive argument. Aristotle affirms the major premiss they share on the basis of a twofold appeal to nature. The principle of distributive justice, the concept as distinguished from the various conceptions of distributive justice, is itself according to nature ( Pol. VII.3.1325b7-10) and so too is one particular standard of worth, the standard of the best polis. Consequently, the question of the status of these three justifications, whether they are purely hypothetical or not, is a question about the minor premiss or premisses of each. In the case of the democratic premiss Aristotle's answer is straightforward: it is sometimes but not always true ( Pol. III.11.1281bl5-21). Hence the justification of democracy is not purely hypothetical. Nor is the justification of absolute kingship. The man who is “like a god among men” ( Pol. III.13.1284a10-11) would be a man of heroic virtue (see VII.14.1332bl6-27); and such a man, Aristotle says, is “rare” ( σπávιoη ) (not nonexistent) ( E.N. VII.1.1145a27-28). The minor premisses of the aristocratic argument describe a situation where all of the free men in a given polis have sufficient wealth for the exercise of the moral and intellectual virtues and where all of the older free men of the polis are men of practical wisdom. In the Politics Aristotle makes only the modest claim that such a situation is possible: It is not possible for the best constitution to come into being without appropriate equipment [that is, the appropriate quality and quantity of territory and of citizens and noncitizens]. Hence one must presuppose many things as one would wish them to be, though none of them must be impossible ( Pol. VII.4.1325b37-38; see also II.6.1265al7-18). But Aristotle appears to subscribe to the principle that every possibility is realized at some moment of time ( Top. 11.11.115bl7-18, Met. Θ.4.1047b3-6, N.2.1088b23-25). This principle together with the claim that the situation described is possible entails that the situation sometimes occurs. Thus even Aristotle's justification of true aristocracy is not purely hypothetical. The final question is Aristotle's way of avoiding Protagorean relativism without embracing Platonic absolutism. The relativist, along with everyone else ( E.N. V.3.1131a13-14, Pol. III.12.1282bl8), can accept the principle of distributive justice: Q(x)/Q(y) = V(T(x))/V(T(y)) And he can concede that particular instances of this principle, particular conceptions of justice, accurately describe the modes of distributing political authority that appear just to particular polises and to particular philosophers. What he denies is that there is any basis for ranking these various conceptions of justice or for singling one out as the best (Plato, Theaet. 172A-B). Aristotle, following in Plato's track ( Laws X.888D7-890D8), maintains against the relativist that nature provides such a basis. But he departs from Plato in his conception of nature. For Plato “the just by nature” ( τó ρυσει δίκ↑oν }) ( Rep. VI.501B2) is the Form of justice, an incorporeal entity ( Phdo. 65D4-5, Soph. 246B8) that exists beyond time and space ( Tim. 37C6-38C3, 51E6-52B2), whereas for Aristotle the sensible world is the realm of nature ( Met. A.1.1069a30-b2). Thus in appealing to nature Aristotle does not appeal to a transcendent standard. Nor does he appeal to his main criterion of the natural, namely, happening always or for the most part. Aristotle's theory of justice is anchored to nature by means of the polis described in Politics VII and VIII, and he regards this polis as natural because it fosters the true end of human life and because its social and political structure reflects the natural hierarchy of human beings and the natural stages of life. Thus the nature that Aristotle's theory of justice is ultimately founded on is human nature. (shrink)

This volume is the product of an important recent conference, convened by His Holiness the Dalai Lama, focusing on the intellectual legacy of the Tibetan philosopher, yogi, and saint Tsongkhapa (1357-1419). Entitled "Jé Tsongkhapa: Life, Thought, and Legacy," the conference commemorated the sixth hundredth anniversary of Tsongkhapa's passing and was held on December 21-23, 2019, at Ganden Monastery in Mundgod, India. Part 1 concerns Madhyamaka, a natural reflection of the very important and well-known contributions Tsongkhapa made to the study of (...) Indian philosophical thought. The first essay, Guy Newland's "Start Making Sense: Finding Tsongkhapa's Middle Way," provides a straightforward and clear introduction to Tsongkhapa's interpretation of Madhyamaka philosophy, showing how Tsongkhapa played an essential role in clarifying Candrakīrti's contributions to Madhyamaka thought. The second essay, "Celebrating Jé Tsongkhapa: The Twofold Object of the Identity View" by Dr. Dechen Rochard explores Tsongkhapa's understanding of Candrakīrti's negation of individual identity. The essay neatly demonstrates the centrality of the practitioner's view of self to the path to spiritual awakening. In the third chapter, "Thinking Beyond Thought: Tsongkhapa and Mipham on the Conceptualized Ultimate," Jay L. Garfield explores Tsongkhapa's views on the nature of ultimate reality, specifically Tsongkhapa's argument that this entails a movement from inferential to direct awareness of emptiness. The essay explores the need for accurate philosophical analysis in the context of meditation practice so as to directly realize the truths about the nature of self and reality that are the objects of the practice. It thus nicely points to the integration of Buddhist theory and practice. The second section of this volume is dedicated to Tsongkhapa's writings on the tantras. In the first chapter in this section, "Tsongkhapa's Masterful Exegesis of Cakrasaṃvara Tantra," I elucidate Tsongkhapa's approach to the study of tantric literature with a focus on his commentary on the Cakrasaṃvara Tantra. Chapter 6 is Gavin Kilty's contribution, "A Lamp to Illuminate the Five Stages: Tsongkhapa's Reformatory Work on Guhyasamāja Tantra." Kilty first surveys the Guhyasamāja tradition and its transmission to Tibet and the two main Indian exegetical traditions, the Ārya and J.ānapāda schools. Outlining Tsongkhapa's approach to the Guhyasamāja Tantra, he then focuses on how the tradition conceptualizes the generation-stage and completion-stage practices. Chapter 7, "The Shadow of Heshang: Tsongkhapa on Chan, Dzokchen, and Mahāmudrā" by Roger R. Jackson. Jackson explores the claim that Tsongkhapa received and secretly transmitted esoteric instructions on advanced meditation practices to realize the nature of mind and awakening. The volume concludes with a section entitled "Moving Minds," which explores Tsongkhapa's legacy and impact both in Tibet and beyond. It opens with "Jé Tsongkhapa's Contribution to Buddhist Hermeneutics" by Geshé Ngawang Samten. Buddhist hermeneutics, as understood here, is a response to the challenge posed by scriptures that appear to contradict one another. Chapter 9, "Tsongkhapa's Hermeneutics and the Perfection of Wisdom," contributed by Gareth Sparham, takes a more focused look at the interpretation of the Perfection of Wisdom literature in both India and Tibet. The tenth chapter is "Jé Tsongkhapa's Teachings and Translations in Mongolian" by Bataa Mishig-Ish, who surveys the dissemination of Tsongkhapa's oeuvre to Mongolia. The final chapter is BhikṣuṇīThubten Chodron's "Learning, Living, and Teaching Bodhicitta: Jé Tsongkhapa's Contribution to Spreading Compassion in the World." Venerable Chodron argues that Tsongkhapa's approach to teaching compassion is particularly suited for the modern, Western context. While this volume does not come close to exhausting the limits of what might be said concerning the impact of Tsongkhapa's work in Tibet and beyond, it does reunite contributions to this study that briefly converged in Preface xi Mundgod, India, just before the global pandemic ushered in a new awareness of our profound human interdependence. Hopefully these essays will advance the appreciation of Tsongkhapa's intellectual legacy in the wider English-speaking world, where he remains a little understood figure of Asian religious history, unlike in the Tibetan-speaking world, where his impact is justly celebrated.

The traditional model theory of first-order logic assumes that the interpretation of a formula can be given without reference to its deductive context. This paper investigates an interpretation which depends on a formula's location within a derivation. The key step is to drop the assumption that all quantified variables must have the same range and to require only that the ranges of variables in a derivation must be related in such way as to preserve the soundness of the inference rules. (...) With each (consistent) derivation there is associated a Buridan-Volpin (orBV) structure [M, {r(x)}] which is simply a Tarski structureM for the language and a map giving the ranger(x) of each variablex in the derivation. IfLK* is (approximately) the classical sequent calculusLK of Gentzen from which the structural contraction rules have been dropped, then our main result reads: If a set of first-ordered formulas has a Tarski modelM, then from any normal derivationD inLK* of can be constructed aBV modelM D=[M, {r(x)}] of where each ranger(x) is finite.

In lieu of an abstract, here is a brief excerpt of the content:Evil as the Good?A Reply to Brook ZiporynDavid R. LoyI was surprised to receive this lengthy response to my short review—yet not displeased, for the important question is, of course, how much Professor Ziporyn's reply helps to clarify the issues at stake, which we agree deserve to be pursued. One of the many admirable aspects of his Evil and/or/as the Good is that, in addition to presenting the Tiantai (...) ethical position in its historical context, it argues forcefully for the validity and relevance of that approach today. Moreover, I am pleased at the way Ziporyn's response focuses the argument of his rich and dense book, so I welcome this opportunity to continue the discussion. And perhaps those who have read this far will also be pleased that I am able to present my main concerns somewhat more concisely.Ziporyn begins with the relationship between ultimate and provisional truth, usually the crux of the matter from a Mahāyāna perspective. In response to a point I make—that ethically the nondual 'ultimate' point of view needs to be supplemented by a provisional 'lower truth' that distinguishes between good and evil—he emphasizes that according to Tiantai "conventional truth and ultimate truth are actually identical" (his italics) and that the conventional truth embraces all possible assertions, beliefs, and positions. Later, he elaborates that "provisional truth is a portion of ultimate truth, in a peculiar omnicentric sort of whole/part relation in which each part in fact contains the whole." The important term remains identity, for according to Tiantai "the idea that two entities might be mutually implicative and dependent, not adventitiously but in their nature, and yet not identical, is logically impossible." Ethically, of course, this means something more than the interdependence of good and evil: it is not only that "the most horrible evils are ineradicable, built into the absolute unchangeable nature of all existence, and fully and eternally present even in Buddhahood," but that "greed, anger, and delusion would be seen to be identical with Buddhahood, in accordance with precisely this Tiantai doctrine of the interpenetration of good and evil."As in the original review, my main point is that this emphasis on the identity of conventional truth and ultimate truth is an important insight, but one that turns out to be quite problematic ethically. Its value is mostly epistemological and metaphysical: it helps us escape from the kind of dualism that often postulates some 'higher' transcendental reality corresponding to a 'higher' ultimate truth. Instead, the 'higher' is not separate from the provisional and conventional, but the truth (whether realized or not) is that the whole 'ultimate' is completely contained within each conventional part or provisional position.Dōgen somewhere makes the point that the goal is not to eradicate concepts (which is a dualistic approach to practice, seeking a purified mind that transcends language) but to liberate concepts. What becomes important is our ability to move [End Page 348] (and play) freely among the multiplicity of linguistic possibilities—in Ziporyn's terms, to 'recontextualize' without getting stuck in any particular context or conceptual system. Nothing is lacking in any of these possibilities; in terms of Indra's Net, each node manifests the whole. We are not liberated from language, except in the sense that we are not trapped in any particular language game; rather, we are liberated in language. We should not blame the victim: the problem is not language itself, but our tendencies to cling to some concepts, et cetera, more than others- including, for example, our dualistic tendency to discriminate between 'good' and 'evil' in order to identify with the former by annihilating the latter (a very timely topic, unfortunately).But good and evil for Ziporyn are more than interdependent. He claims that they are identical, and that is where difficulties arise. The epistemological point about the identity of the two truths becomes more problematical when we move into ethics, where the 'cash value' is somewhat more obvious and immediate, in the sense that we need ethics to help us cope with moral choices that we find ourselves required to make in daily life, in circumstances not always...

This paper provides a systematic literature review, analysis and discussion of methods that are proposed to practise ethics in research and innovation. Ethical considerations concerning the impacts of R&I are increasingly important, due to the quickening pace of technological innovation and the ubiquitous use of the outcomes of R&I processes in society. For this reason, several methods for practising ethics have been developed in different fields of R&I. The paper first of all presents a systematic search of academic sources that (...) present and discuss such methods. Secondly, it provides a categorisation of these methods according to three main kinds: ex ante methods, dealing with emerging technologies, intra methods, dealing with technology design, and ex post methods, dealing with ethical analysis of existing technologies. Thirdly, it discusses the methods by considering problems in the way they deal with the uncertainty of technological change, ethical technology design, the identification, analysis and resolving of ethical impacts of technologies and stakeholder participation. The results and discussion of our literature review are valuable for gaining an overview of the state of the art and serve as an outline of a future research agenda of methods for practising ethics in R&I.

Colour has often been supposed to be a subjective property, a property to be analysed orretly in terms of the phenomenological aspects of human expereince. In contrast with subjectivism, an objectivist analysis of color takes color to be a property objects possess in themselves, independently of the character of human perceptual expereince. David Hilbert defends a form of objectivism that identifies color with a physical property of surfaces - their spectral reflectance. This analysis of color is shown to provide (...) a more adequate account of the features of human color vision than its subjectivist rivals. The author's account of colro also recognises that the human perceptual system provides a limited and idiosyncratic picture of the world. These limitations are shown to be consistent with a realist account of colour and to provide the necessary tools for giving an analysis of common sense knowledge of color phenomena. (shrink)

David Lewis objected to theories that posit necessary connections between distinct entities and to theories that involve a magical grasping of their primitives. In On the Plurality of Worlds, Lewis objected to nondescript ersatzism on these grounds. The literature contains several reconstructions of Lewis’ critique of nondescript ersatzism but none of these interpretations adequately address his main argument because they fail to see that Lewis’ critique is based on broader methodological considerations. I argue that a closer look at his (...) methodology reveals the broader objection he presented against nondescript ersatzism. This objection, I further argue, remains a challenge for the ersatzer who posits structure-less entities as possible worlds. (shrink)

A number of ways of taxonomizing human learning have been proposed. We examine the evidence for one such proposal, namely, that there exist independent explicit and implicit learning systems. This combines two further distinctions, (1) between learning that takes place with versus without concurrent awareness, and (2) between learning that involves the encoding of instances (or fragments) versus the induction of abstract rules or hypotheses. Implicit learning is assumed to involve unconscious rule learning. We examine the evidence for implicit learning (...) derived from subliminal learning, conditioning, artificial grammar learning, instrumental learning, and reaction times in sequence learning. We conclude that unconscious learning has not been satisfactorily established in any of these areas. The assumption that learning in some of these tasks (e.g., artificial grammar learning) is predominantly based on rule abstraction is questionable. When subjects cannot report the rules that govern stimulus selection, this is often because their knowledge consists of instances or fragments of the training stimuli rather than rules. In contrast to the distinction between conscious and unconscious learning, the distinction between instance and rule learning is a sound and meaningful way of taxonomizing human learning. We discuss various computational models of these two forms of learning. (shrink)

I might summarize this section by saying that the English tenses, according to this analysis, form quite a motley group. PAST, PRES and FUT serve to relate reference time to speech time, while WOULD and USED-TO behave like Priorian operators, shifting the point of evaluation away from the reference time. HAVE also shifts the point of evaluation away from the reference time, but in a more complicated way. And FUT, in contrast to PRES and PAST, is a substitution operator, putting (...) the reference time of its clause in the plate of the speech time of subordinate clauses. (shrink)

There are serious reasons for accepting each of these propositions individually but there are apparently insurmountable difficulties with accepting all three of them simultaneously if we assume that color is a single property. 1) and 2) together seem to imply that there is some property which all organisms with color vision can see and 3) seems to imply that there can be no such property. If these implications really are valid then one or more of these propositions will have to (...) be rejected in spite of whatever reasons can be given for their apparent acceptability. Before going on to discuss possible resolutions of this apparent contradiction it is worth pointing out there our three propositions are not all of a kind. Proposition 1) is a metaphysical thesis about the ontological status of color and proposition 3) is an empirical thesis about what properties organisms with color vision are capable of detecting. If you accept 1) then 2) will appear to verge on the trivial, but if 1) is denied then the status of 2) will appear more problematic. In what follows I will have more to say about why we either should or should not accept all three of these propositions. (shrink)

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

In their recent paper ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’ Savulescu and Cameron attempt to argue the case for subjecting the ‘elderly’ to limits not imposed on other generations. We argue that selective lockdown of the elderly is unnecessary and cruel, as well as discriminatory, and that this group may suffer more than others in similar circumstances. Further, it constitutes an unjustifiable deprivation of liberty.

Solar radiation management (SRM), a form of climate engineering, would offset the effects of increased greenhouse gas concentrations by reducing the amount of sunlight absorbed by the Earth. To encourage support for SRM research, advocates argue that SRM may someday be needed to reduce the risks from climate change.

The Doctrine of Doing and (...) Allowing, and perhaps the Doctrine of Double Effect, shows that the argument is weaker than it appears. (shrink)
