[Open access] In this book symposium the author takes up questions from phenomenology, hermeneutics, ethical theory, and intellectual history raised by a group of scholarly interlocutors from a range of backgrounds. In the course of engaging with these issues, he discusses, inter alia, McDowell’s realism, Jonathon Lear’s work on the end of a world, Michael Oakeshott’s view of selfhood, Heidegger’s conception of Jemeinigkeit, Uexküll’s notion of Umwelt, and Gadamer’s hermeneutic conception of truth.

In this paper, I attempt to show that the moral/conventional distinction simply cannot bear the sort of weight many theorists have placed on it for determining the moral and criminal responsibility of psychopaths. After revealing the fractured nature of the distinction, I go on to suggest how one aspect of it may remain relevant—in a way that has previously been unappreciated—to discussions of the responsibility of psychopaths. In particular, after offering an alternative explanation of the available data on psychopaths and (...) their judgments of various sorts of norm transgressions, I put forward a hybrid theory of their responsibility, suggesting how they might be criminally responsible, while nevertheless failing to meet the conditions for an important arena of moral responsibility.

In this article, I respond to David McIvor’s and Lars Rensmann’s discussion of my recent book, The Politics of Repressed Guilt: The Tragedy of Austrian Silence (2018, Edinburgh University Press). Both invited me to clarify my use of Arendt in my conception of embodied reflective judgment. I argue for a stronger connection between judgment and emotions than Arendt because one can effectively shut down critical thinking if one uses defense mechanisms to repress feelings of guilt. In response to McIvor, (...) I discuss the idea of the “subject-in-outline” and “embodied reflective spaces” to overcome the guilt/defense complex to engender a reparative politics of justice. Finally, in response to Rensmann, I point out that the lingering culture of repressed guilt helps us explain the general conditions that contributed to the rise of the far and extremist right in Austria, which I develop further in my new book Analyzing the Far Right.

Derek Parfit claims that, at certain times and places, the metaphysical units he labels *'selves" may be thought of as the morally significant units (I.e., the objects of moral concern) for such things as resource distribution, moral responsibility, commitments, etc. But his concept of the self is problematic in important respects, and it remains unclear just why and how this entity should count as a moral unit in the first place. In developing a view I call *'Moderate Reductionism," I attempt (...) to resolve these worries, first by offering a clearer, more consistent account of what the concept of *'self ' should involve, and second by arguing for why selves should indeed be viewed as moral (and prudential) units. I then defend this view in detail from both *'conservative" and *'extreme" objections. (shrink)

Living organisms are the ultimate survivalists, having evolved phenotypes with unprecedented adaptability, ingenuity, resourcefulness, and versatility compared to human technology. To harness these properties, functional descriptions and design principles from all sources of biodiversity information must be collated − including the hundreds of thousands of possible survival features manifest in natural history museum collections, which represent 12% of total global biodiversity. This requires a consortium of expert biologists from a range of disciplines to convert the observations, data, and hypotheses into (...) the language of engineering. We hope to unite multidisciplinary biologists and natural history museum scientists to maximize the coverage of observations, descriptions, and hypotheses relating to adaptation and function across biodiversity, to make it technologically useful. This is to be achieved by developments in meta‐ taxonomic classification, phylogenetics, systematics, biological materials research, structure and morphological characterizations, and ecological data gathering from the collections − the aim being to identify and catalogue features essential for good biomimetic design.

This paper attempts to show how a reductionist approach to the metaphysics of personal identity might well be most compatible with a form of contractualism, not utilitarianism.

Evolution is frequently concentrated in bursts of rapid morphological change and speciation followed by long‐term stasis. We propose that this pattern of punctuated equilibria results from an evolutionary tug‐of‐war between host genomes and transposable elements (TEs) mediated through the epigenome. According to this hypothesis, epigenetic regulatory mechanisms (RNA interference, DNA methylation and histone modifications) maintain stasis by suppressing TE mobilization. However, physiological stress, induced by climate change or invasion of new habitats, disrupts epigenetic regulation and unleashes TEs. With their capacity (...) to drive non‐adaptive host evolution, mobilized TEs can restructure the genome and displace populations from adaptive peaks, thus providing an escape from stasis and generating genetic innovations required for rapid diversification. This “epi‐transposon hypothesis” can not only explain macroevolutionary tempo and mode, but may also resolve other long‐standing controversies, such as Wright's shifting balance theory, Mayr's peripheral isolates model, and McClintock's view of genome restructuring as an adaptive response to challenge.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Christian Ethics in a Technological Age by Brian BrockDavid W. GillChristian Ethics in a Technological Age Brian Brock Grand Rapids, Mich.: Eerdmans, 2010. 408 pp. $34.00Brian Brock is a lecturer in moral and practical theology at the University of Aberdeen, Scotland, and the author of Singing the Ethos of God: On the Place of Christian Ethics in Scripture (Eerdmans, 2007). Christian Ethics in a Technological [End Page 188] (...) Age was originally Brock’s doctoral thesis at King’s College, London. Brock begins by highlighting and finding wanting the modern practice of “technology assessment” as epitomized in the establishment of the US Office of Technology Assessment in 1972. We live in a world, a milieu, of ever-multiplying new technologies and technological artifacts. “Technology assessment” attempts to evaluate their impacts as thoroughly as possible through scientific, managerial methods. Costs and benefits, benefits and harms, short-term and long-term, near and distant effects: how can we measure what we know and extrapolate to what we need to know?In part 1 Brock engages in some detail the thinking of Martin Heidegger, George Grant, and Michel Foucault on technology. Although Heidegger and Foucault in particular are not ultimate authorities for Brock, his chapters on their work provide a helpful philosophical critique of the inadequacies of today’s narrow managerial approaches to technological assessment. The real problems lie much deeper: in the ways technology reflects and restructures our whole way of thinking about life, materiality, subjects and objects, and means and ends.Having used Heidegger, Grant, and Foucault to unmask the complex reality of technology in the modern era, Brock turns in part 2 to Augustine, Karl Barth, and Bernd Wannenwetsch to try to build a Christian theological ethics of technology and work that will, in the end, provide a richer texture for our interactions with the questions raised by new technologies. In briefest terms, he argues that our questions and judgments about technology should arise within the church gathered for worship rather than within the management team gathered for measurement of effects. It could be said that in the former it is God who questions technology whereas in the latter technology and its servants constitute an implicit challenge to God and the world external to themselves.Brock’s study will be of particular interest to students of his primary six sources: Heidegger, Grant, Foucault, Augustine, Barth, and Wannenwetsch, whose ideas and quotations dominate the pages of this book. Without any doubt Christian Ethics in a Technological Age is a significant work that deserves careful consideration in graduate seminars and among specialists in the field; nonetheless, I have three criticisms. First, the work would have been much stronger if it demonstrated awareness and understanding of the work of Jacques Ellul, Carl Mitcham, Albert Borgmann, and other leading thinkers in this arena. Second, Brock’s writing style (long, complex Germanic sentence structures, eccentric vocabulary choices such as the recurrent use of “purchase”) gets in the way of successful communication—especially with the very managers and technologists he presumably would like to influence. Third, while sympathizing with his rejection of managerial formulas for analysis, some much more concrete and practical counsel on the implications of his position would have been [End Page 189] helpful. How do trust and trustworthiness get reestablished? How does a worshipping congregation hear God’s guidance about its particular engagements with technologies? We have some eloquent statements of the concepts but little by way of illustration or example.David W. GillGordon-Conwell Theological SeminaryCopyright © 2013 Society of Christian Ethics... (shrink)

Ursula K. Le Guin’s classic work of anarchist literature, _The Dispossessed_ (1974), is preoccupied with the issue of imprisonment. This is hardly surprising given anarchism’s longstanding critical engagement with the prison as state apparatus. For classical anarchists, the prison represents one of the most vile and visible examples of state repression. However, while the abolition of prisons constitutes one of the fundamental goals of anarchism, the alternatives put forth by classical anarchist thinkers risk perpetuating the underlying power relations of carceral (...) justice by encouraging social shaming and the policing of norms. The anarchist society of _The Dispossessed_ uses these techniques to discourage the accumulation of power in order to create an egalitarian society. Unfortunately, these same techniques encourage a conformity that hinders other anarchist values, such as creativity and individual self-determination. In essence, the anarchist society depicted in the novel replaces the literal prison with a different form of imprisonment—the social prison, which continues the repressive function of the state through different means. By creating an “ambiguous” anarchist utopia, Le Guin anticipates the critiques of classical anarchism formulated by poststructural and postmodern anarchist theorists. These critiques are most evident in the theme of imprisonment that threads throughout the novel. (shrink)

This essay presents the use-first-and-investigate-later (UFAIL) approach to technological use through two case studies: the atomic bomb in World War II and chemical defoliants during the Vietnam War. The methodology of UFAIL is as follows: despite limited understanding of an array of potential effects (medical, environmental, etc.), technology users employ a commitment to ex post facto investigations of these effects. In generalizing these cases, the essay argues (a) that failure to check rapid technological uptake will result in continued disaster and (...) (b) the abatement of the negative consequences of UFAIL is a more tempered approach to the infiltration of technologies into society by rigorous and preemptive investigation into the potential effects of a technology.

Two recent studies by Parisi et al.1 and Ranz et al.,2 catalogue sex differences in gene expression across the whole genome of the fruit fly Drosophila melanogaster. Both report striking associations of sex‐biased gene expression with the X chromosome. Genes with male‐biased expression are depauperate on the X chromosome, whereas genes with female‐biased expression show weaker evidence of being in excess. A number of evolutionary hypotheses for the expulsion or exclusion of male‐biased genes from the X chromosome have been suggested. (...) None is entirely consistent with the available evidence.

Modern industrialized populations lack the strong positive correlations between wealth and reproductive success that characterize most traditional societies. While modernization has brought about substantial increases in personal wealth, fertility in many developed countries has plummeted to the lowest levels in recorded human history. These phenomena contradict evolutionary and economic models of the family that assume increasing wealth reduces resource competition between offspring, favoring high fertility norms. Here, we review the hypothesis that cultural modernization may in fact establish unusually intense reproductive (...) trade-offs in wealthy relative to impoverished strata, favoring low fertility. We test this premise with British longitudinal data (the Avon Longitudinal Study of Parents and Children), exploring maternal self-perceptions of economic hardship in relation to increasing family size and actual socioeconomic status. Low-income and low-education-level mothers perceived the greatest economic costs associated with raising two versus one offspring. However, for all further increases to family size, reproduction appears most expensive for relatively wealthy and well-educated mothers. We discuss our results and review current literature on the long-term consequences of resource dilution in modern families. (shrink)

Despite the importance of linguistic disclosure for philosophical hermeneutics there has been a conspicuous lack of attention to the question of how linguistic disclosure actually works. I examine the mechanics of disclosure by drawing on Gadamer’s philosophical hermeneutics as well as Ricoeur’s concept of translation and his theory of metaphor. My claim is that the background horizon of the unsaid that differs between languages enables each to disclose different things. This situation underscores the importance of engaging in East-West comparative philosophy, (...) of philosophizing across what Ricoeur calls the radical “fold” (pli) in what can be thought and experienced.

This book discusses the development of Edward Tolman's purposive behaviourism from the 1920s to the 1950s, highlighting the tension between his references to cognitive processes and the dominant behaviourist trends. It shows how Tolman incorporated concepts from European scholars, including Egon Brunswik and the Gestalt psychologists, to justify a more purposive form of behaviourism and how the theory evolved in response to the criticisms of his contemporaries. The manuscript also discusses Tolman's political activities, culminating in his role in the California (...) loyalty oath controversy in the 1950s. Tolman was involved in a number of progressive causes during his lifetime, activities that drew the attention of both state legislators in California and the Federal Bureau of Investigation. It treats Tolman's theoretical and political activities as emanating from the same source, a desire to understand the learning process in a scientific manner and to apply these concepts to improve the human condition.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Time, Will, and Purpose: Living Ideas from the Philosophy by Randall E. AuxierDavid W. RodickRandall E. Auxier Time, Will, and Purpose: Living Ideas from the Philosophy of Josiah Royce Chicago, Illinois: Open Court Press, 2013. 424 pages, incl. index.Randy Auxier’s long awaited book is a major milestone in Royce studies—a systematic tour de force engaging the entire course of Royce’s thought. Auxier’s goal is to achieve an all-round (...) reappraisal of Royce, setting the record straight about major misconceptions accrued throughout the course of Royce scholarship over the past 65 years—if not longer.One of the most significant events in Royce scholarship during the 20th Century was the appearance of John E. Smith’s Royce’s Social Infinite: The Community of Interpretation.1 As Auxier notes: “For the purposes for which it was intended, Smith’s book will never be surpassed in its excellence. Smith’s book is outstanding in numerous ways … but its clarity and brevity are high among its chief virtues” (13). The problem with Smith’s book, for Auxier, is that readers have used it for a purpose it was never intended to serve—that of a crutch or “shortcut to a full understanding of Royce” (13). This tendency has had a compounding effect: “[N]ot only scholarship, but scholarly consciousness about Royce is formed by Smith’s book” (14). [End Page 166]The shortcomings of Smith’s book are partly due lack of available historical information concerning the Peirce-Royce relationship at the time it was written: “The inferences about Peirce and Royce that Smith drew from the available resources were mostly warranted at the time, but they turned out to be only a drop in the pond, if not the ocean, of what was the case” (15–16). But the most damning consequence of Smith’s book is its claim that Royce’s thought underwent a decisive shift in its later stages: “[T]he all-important change in Royce’s conception of the Absolute consists in the shift from the idea that the Infinite thought is an all-embracing consciousness apprehending at a glance all truth … to the idea that the Infinite is actual as a well-ordered system … having a generally triadic form and involving a type of cognition called interpretation” (19).2 Once a bifurcation between the “early” and the “later” Royce is introduced, the tendency is to identify Royce’s “Peircean moment” of 1912 as the decisive point of rupture between the “two Royces”—an incorrect view stemming from the inability to take a longer view of the Peirce-Royce relationship:But our recognition of the intense, constant and long term character of their exchange also eliminates the supposition that that Royce took a sudden turn in 1912. It is not a “Peircean turn” due to some late discovery, it was an insight about how to use Peirce’s theory of signs (which Royce had known for years) as a tool for the application of his (long held) triadic theory of community. … Peirce did not save Royce from absolutism or turn him in any fundamentally new direction.(17)Failure to grasp the integral unity of Royce’s thought results in a tendency to miss the ethical basis of his philosophy—“ethics as first philosophy.” Unlike Smith, and others, who err toward the side of viewing Royce’s philosophical project as an epistemological attempt at a conception of knowledge warranted in terms of ability to provide truth and certainty, “Royce’s method is a hypothetical ontology … not aimed primarily at securing certainty or knowledge, but rather at maintaining intellectual norms … that govern clear thinking and facilitate intelligent practice and action” (23). Royce’s hypothetical ontology underscores the religious dimension of experience because practical, faith-based postulates are recognized as unavoidably intertwined in the process of knowing. Living in a universe of postulates requires formulating ideals as if they were ontologically constitutive; and acting in accordance with these ideals in a way that validates their existence—while recognizing the fallibility and risk of the entire enterprise. Royce’s argument amounts to saying “[W]ell no, we don’t get more than postulates, but don... (shrink)

Ethical theories must include an account of the concept of a person. They also need a criterion of personal identity over time. This requirement is most needed in theories involving distributions of resources or questions of moral responsibility. For instance, in using ethical theories involving compensations of burdens, we must be able to keep track of the identities of persons earlier burdened in order to ensure that they are the same people who now are to receive the compensatory benefits. Similarly, (...) in order to attribute moral responsibility to someone for an act, we must be able to determine that that person is the same person as the person who performed the act. Unfortunately, ethical theories generally include a concept of a person and criteria of personal identity either as notions implied or presupposed by the already worked out theory, with little or no argument given in support of them. But both approaches are unsatisfactory, for each runs the risk of ignoring certain fundamental features of the way persons actually are. What is needed first is a plausible metaphysical account of persons and personal identity to which an ethical theory might then conform and apply. Derek Parfit has attempted to provide such an account in Reasons and Persons, where he argues for what he calls the reductionist view of persons and personal identity and then attempts to show how such a conception provides a metaphysical background that lends important partial support to utilitarianism. 1 But Parfit’s metaphysical view is neutral between two possible conceptions of personhood, and utilitarianism presupposes the truth of the more radical of the two conceptions, which precludes the possibility of there being a class of goods crucial to any plausible ethical theory. Utilitarianism thus presupposes a wildly implausible conception of persons, and so is itself implausible. (shrink)

The philosophy of Gabriel Marcel is informed by the classical tradition of American philosophy – most notably William James, William Ernest Hocking and Josiah Royce. At a time when Marcel scholarship is at risk of being eclipsed by abstract modes of philosophical discourse, a return to the classical American sources of Marcel's thought is vital. This article investigates Marcel's thought from the standpoint of James’ conception of radical empiricism, the primacy of intersubjective experience in Hocking’s philosophy, and the importance of (...) praxis in the later Royce. Marcel’s openness to the classical American tradition in philosophy is a function of the Catholic character of Marcel’s thought. (shrink)

The interest in and enthusiasm for urban agriculture (UA) in urban communities, the non-profit sector, and governmental institutions has grown exponentially over the past decade. Part of the appeal of UA is its potential to improve the civic health of a community, advancing what some call food democracy. Yet despite the increasing presence of the language of civic agriculture or food democracy, UA organizations and practitioners often still focus on practical, shorter-term projects in an effort both to increase local involvement (...) and to attract funding from groups focused on quantifiable deliverables. As such, it seems difficult to move beyond the rhetoric of food democracy towards significant forms of popular participation and deliberation within particular communities. In this paper we provide a theoretical framework—deep democracy—that helps to contextualize nascent attempts at civic agriculture or food democracy within a broader struggle for democratic practices and relationships. We argue that urban agriculture efforts are well positioned to help citizens cultivate lasting relationships across lines of difference and amidst significant power differentials—relationships that could form the basis of a community’s collective capacity to shape its future. We analyze the theory of deep democracy through recent experiences with UA in Denver, Colorado, and we identify ways in which UA can extend its reach and impact by focusing more consciously on its political or civic potential.

The Merge model suggests that lexical effects in phonemic processing reflect the activation of post-lexical phonemic representations that are distinct from prelexical phonemic input representations. This distinction seems to be unmotivated; the phoneme fails to capture the richness of prelexical representation. Increasing the information content of input representations minimizes the potential necessity for top-down processes.

In this essay David Black claims that, if one pieces together the many sketches of educational decorum found in the Confucian Analects, one will discover three types of misguided student; that is, one will come to recognize that Confucius admonishes three types of insensitive learners who, due to the lure of personal advantage and social rhetoric, begin to mismanage the exchanges of respect particular to the educational process. These students misappropriate key rituals of decorum and dialogue, and consequently create (...) a degree of disorder that, for Confucius, actually threatens the existence of civil society. (shrink)

In birds and frogs, species pairs retain the capacity to produce viable hybrids for tens of millions of years, an order of magnitude longer than mammals. What accounts for these differences in relative rates of pre- and postzygotic isolation? We propose that reproductive mode is a critically important but previously overlooked factor in the speciation process. Viviparity creates a post-fertilization arena for genomic conflicts absent in egg-laying species. With viviparity, conflict can arise between: mothers and embryos; sibling embryos in the (...) womb, and maternal and paternal genomes within individual embryos. Such intra- and intergenomic conflicts result in perpetual antagonistic coevolution, thereby accelerating interpopulation postzygotic isolation. In addition, by generating intrapopulation genetic incompatibility, viviparity-driven conflict favors polyandry and limits the potential for precopulatory divergence. Mammalian diversification is characterized by rapid evolution of incompatible feto-maternal interactions, asymmetrical postzygotic isolation, disproportionate effects of genomically-imprinted genes, and “F2 hybrid enhancement.” The viviparity-driven conflict hypothesis provides a parsimonious explanation for these patterns in mammalian evolution.

Chappell Soka University Guiding Issues How do I understand my own identity as a religious person in light of the fact that I am open to the validity of the beliefs held by other traditions?Has my understanding of my own religious tradition been transformed, purified, and enriched by the (...) ways in which I have come to understand the other traditions?Have I been changed by the dialogue, or do I remain the same? What difference has the dialogue made in my life, personally or theologically?How would I respond to this topic from the point of view that I am a religious person engaged in a specific area of expertise (environment, philosophy, etc.)? Thesis The increased mobility and diversity of relationships in the contemporary world has often made religious identity a complex issue, hardening it for some people and diffusing it for others. But in either case, I wish to challenge the view that highlights beliefs as a key to defining identity and instead propose that many other factors might be more important, and that in religious life identity is a secondary issue. Being Christian I was born, baptized, and raised in the Christian tradition. My father was a United Church of Canada minister and I became a United Church of Canada minister, while my mother was a Baptist and my brother became a Baptist minister. Religious values were important in my upbringing and throughout my adult life. While I have maintained a concern for ultimate values, however, my own beliefs have undergone radical changes. I am sure that many in the Christian community would say that I am no longer a Christian, but I have never taken that view and have never taken the step to renounce my ordination as a Christian minister. Instead, I question the assumption that beliefs are the best way to define a religious life or religious identity. [End Page 9]In 1961 I had the good fortune to go to McGill University to study with Wilfred Smith, and from him I have learned not to focus on the "beliefs" of others—namely, intellectual constructs—but on the "faith" of others as much more encompassing and important. Some religious communities—like the Jain and the Confucian—do not care about one's beliefs, only about one's practice, both ritually and morally. Wilfred Smith called it orthopraxy, rather than orthodoxy, and it provides an alternative means of marking religious identity.Why should I feel bound by the efforts of Emperor Constantine when he convened a church council in 325 CE to define Christian identity or by subsequent efforts of church institutions to do the same? Today, my Christian identity is nurtured and expressed by a constellation of moral values and cosmic trust, of faith and actions, that are connected to the early Jesus movement, especially as articulated by John Dominic Crossan. Living as we do in the modern era, we have very different beliefs about history and cosmology from these early Christians, as John Robinson discussed forty years ago in his book Honest to God. My affection for Christian church life and the early Jesus movement involves other factors than the concerns of those who formed Christian creeds. The Trinitarian doctrine makes sense as a conglomeration made from the conceptualization of several historical experiences important in the early Christian community, but the Trinitarian concept does not clarify or enhance my contemporary experience.In spite of the Trinitarian formulation, I still honor and value the powerful and enduring influence of my Christian upbringing. As a result, I have not renounced the name "Christian" or my ordination as a Christian minister, even though I have grown increasingly away from them. I am still the second son of Lynsin and Mary Chappell. Even though my parents may seem to be dead and gone, they are still alive for me. I treasure them and I still live my life in their embrace, as well as in the embrace of the fellowship of... (shrink)
