This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

Ectogestation technology, when feasible, will permit fetal development within an artificial womb. Ectogestation is termed ectogenesis when it is full (gestation occurs exclusively within an artificial womb post in vitro fertilisation) or partial (artificial gestation occurs during the course of in vivo gestation, post a caesarean-like fetal transfer). In what follows, I explore the implications for the gestational versus moral parenthood debate recently spotlighted by Benjamin Lange1 for various alternative uses of ectogestation compared to the baseline case of in vivo (...) gestation. I contrast ectogestation in four different contexts with in vivo gestation followed by vaginal delivery. I document the relevant outcomes, burdens and harms in particular, to the gestating mother, the biological father, the fetus and the child into whom it will develop. The focus on harms in considering intraparental claims to parenthood follows Lange’s focal article1: importantly, however, I focus not on harms from separation from the gestational procreator (as in adoption cases) but instead on harms arising from the use of ectogestation in various forms. I note at the outset, how, for each case discussed below, I indicate opportunities for each biological parent to establish voluntarism-based claims to moral parenthood. In the analyses, except where specifically noted, the default implication is that it is …. (shrink)

The disruptions to everyday life wrought by the COVID-19 pandemic include distortions in the experience of time, as reported widely by ordinary citizens and observed by journalists and social scientists. But how does this temporal disruption play out in different time scales—in the individual day as opposed to the medium- and long-term futures? And how might place influence how individuals experience and understand the pandemic's temporal transformations? This essay examines a range of temporal disruptions reported in day diaries and surveys (...) submitted to the Everyday Life in Middletown project, an online archive that has been documenting ordinary life in Muncie, Indiana, USA since 2016. Viewing these materials as instances of life writing, the essay probes the interactions between temporal disruptions and the local setting as they inflect the autobiographical selves our writers construct in their pandemic writings. It shows how living in Muncie—a postindustrial city with its particular combination of historical, demographic, economic, social, and political dynamics—structures the autobiographical stories available to our writers, and how the disruption of time produces new variations and problems for life writing. In the midst of a global crisis, we glimpse the pandemic's reshaping of a local structure of feeling in which a pervasive, local narrative of civic decline frames individual self-fashioning.

Postnatal parent-infant physiological regulatory effects described in the previous paper (Part I) are viewed here as being biologically contiguous with events that occur prenatally, preparing and sensitizing the fetus to the average microenvironment into which the infant is expected, based on its evolutionary past, to be born. Following McKenna (1986), evidence (some of which is circumstantial) is presented concerning fetal hearing and fetal amniotic liquid breathing as they are affected both by maternal cardiovascular blood flow sounds in the uterus and (...) by fluctuating maternal blood sugar levels. These data are linked in turn to the infant’s postulated postnatal responsivity to parental sensory cues, including auditory and vestibular respiratory cues that may assist infants as they “learn” to breathe and, for some, to resist a SIDS event. Data on the respiratory and vocalizing behavior of normal and hearing-impaired persons are used to show that not all forms of human breathing are innate; some forms develop with experience. These data reveal how human infants learn, for example, to coordinate higher and lower brain respiratory nuclei in the context of learning initially to cry with intent and purpose and later to speak. Voluntary, cortex-based breathing emerges at the same time that infants are most likely to die from SIDS, between 2 and 4 months of age. This switch between voluntary and involuntary breathing during both sleep (while dreaming) and wake cycles, which depends on the integration of higher cortical and lower brain stem nuclei, is complex and is possibly the basis of the human species’ unique susceptibility to SIDS—a syndrome as yet unrecognized in other species. These human infant vulnerabilities, including delayed maturity, can explain in part why natural selection ought to favor increased infant sensitivity to parental sensory cues provided by a caregiver—stimuli available in the evolving parental care environment that included parent-infant co-sleeping for more than 4–5 million years of human evolution.

In lieu of an abstract, here is a brief excerpt of the content:The Peculiarly Favored Condition of GeneticsJames J. Lee, PhD (bio) and Damien Morris, MSc (bio)Turkheimer and Greer (2024) (henceforth “T&G”) make some fair points about problems in the scientific profession, including the regrettable tendency to promise practical applications of research that then never materialize. However, T&G’s sustained critique of a body of work associated with one particular researcher to make these general points struck us as uncharitable. More pressingly, (...) we feel that the far-reaching conclusions that T&G attempt to draw from the results they review from the Spit for Science (S4S) cohort are unjustified and risk misleading readers that psychiatric and behavioral genetics is in a parlous state.T&G state that S4S “produced a clear answer to the question it was designed to address,” namely, that its results “unambiguously contradict the hypothesis that alcohol-related behaviors have a meaningful genetic basis.” But S4S cannot possibly have provided affirmative evidence for the null hypothesis, because as a single cohort it lacked the statistical power to do so. Elsewhere T&G acknowledge that the sample size of S4S does not suffice for many purposes; they cannot have it both ways. When GCTA has been applied to samples of greater size, it has unambiguously supported the hypothesis that alcohol-related behaviors have a meaningful genetic basis. The UK Biobank yielded estimates exceeding 0.10 for the contribution of single nucleotide polymorphisms (SNPs) with minor allele frequency of greater than 0.05 to the heritability of drinks per week, estimates more than ten times their standard errors (Liu et al., 2019).This heritability contributed by common variants is sometimes called “SNP heritability,” and T&G disparage it for the alleged “disadvantage of being substantially smaller” than “twin and family heritabilities.” Nowhere do T&G consider what the precise numbers actually mean—an approach that can be hazardous to your scientific health, as the late John Loehlin might have said. Let us, then, consider these numbers. Under a model of pure neutrality, SNP and pedigree narrow-sense heritabilities should be fairly close, essentially as a result of factors p(1 − p) canceling in the multiplication of the numbers of SNPs to be found at a given allele frequency by the average heritability contributed per SNP (Hill, 2010). If SNP and pedigree heritabilities are not close, then natural selection must have been acting on [End Page 441] the trait, preventing new mutations of large effect from becoming common and thereby concentrating heritability at allele frequencies lower than those typically studied in genome-wide association studies (GWAS). This deduction has been abundantly confirmed: the tendency of GWAS SNPs to reside in evolutionarily conserved regions (Finucane et al., 2015; Kim et al., 2019), the younger age of GWAS SNPs when compared to control SNPs of comparable frequencies (Gazal et al., 2017), the discovery of several rare variants with larger effects than those observed in typical GWAS (Barton et al., 2021; Chen et al., 2023; Marouli et al., 2017), the directly measured deleterious fitness effects of mutations in evolutionarily constrained genes (Gardner et al., 2022), and the substantial additional genetic variance accumulated when rare variants are included in GCTA-type studies, sometimes enough to close the gap between SNP and pedigree heritabilities (Evans et al., 2018; Jang et al., 2022; Pathan et al., 2024; Wainschtein et al., 2022).The genetic architecture of a typical quantitative trait consists of many sites across the genome that can mutate to affect it, numbering potentially in the millions (Agarwala et al., 2013; Zeng et al., 2021), of which those that are common SNPs have very small effects as a result of selection. This is the message, but T&G seem to find fault with the messenger, painting “tiny” effect sizes as an embarrassment to the field of behavioral genetics as a whole. We prefer to view the finding of high polygenicity as a revelation about nature, rather than as a debating point. What is this finding telling us? If one takes the action of stabilizing selection as the initial assumption (Uyeda et al., 2011), then the extreme polygenicity revealed by GWAS becomes part of the answer to the question regarding how traits can...

In lieu of an abstract, here is a brief excerpt of the content:BALTHASAR'S USE OF THE THEOLOGY OF AQUINAS }AMES J. BUCKLEY Loyola College in Maryland Baltimore, Maryland T HE AIM OF THIS essay is to raise some questions about the internal consistency of Hans Urs von Balthasar's use of the theology of Thomas Aquinas. These are genuine questions. That is, they are not questions ("Is Balthasar's use of Aquinas consistent?") disguising or masking answers ("Balthasar's use of Aquinas is inconsistent"). (...) While I hope the questions set an agenda for disputations between students of these two theologians, my aim is not to settle the many disputations between the theologies of Aquinas and Balthasar, but to propose some quaestiones disputatae. In Balthasar's terms, the aim is to set up the theater and put some characters on the stage, not to stage the drama itself. Why bother? First, Balthasar's theology arises out of a tradition critical of the theology of Aquinas, and students of Aquinas can only ignore such objections at the price of abandoning Aquinas's habit of responding to such criticisms. The locus classicus of this critique is Balthasar's claim that he omits Aquinas from his canon of theological aestheticians because Aquinas is one of those whose "deep and lucid philosophical aesthetics" has "failed to achieve a theological translation, that is, to be seen as the unfolding of a theology based on biblical revelation" (GL II, 21).1 Thomas Aquinas (Balthasar later says) "was more of a philosopher than a theologian" (GL III, 9). We shall see later that ' I shall use the following abbreviations: ST = Summa Theologiae. Latin text and English translation, ed. Thomas Gilby, various translators (New York: McGraw-Hill; London: Eyre & Spottiswoode, 1964-80). GL =The Glory ofthe Lord: A Theological Aesthetic, ed. Joseph Fessio, S.J., and John Riches, various translators, 7 vols. (San Francisco: Ignatius Press; New York: Crossroad Publications, 1982-91). 517 518 JAMES J. BUCKLEY Balthasar also mentions other objections to Aquinas. In fact, part of my argument will be that this central criticism of Thomas's aesthetics is intelligible only against the background of other even more important criticisms of Aquinas's theology. I ought also to note at this early stage, however, that Balthasar 's criticisms of Aquinas are almost always carefully qualified. For example, in the locus classicus just cited, Balthasar objects to Aquinas's aesthetics, not his ethics or metaphysics; indeed, it is a criticism of Aquinas's theological aesthetics, not his philosophical aesthetics. Still further, Balthasar even says it "would perhaps" be possible to develop the "implicit" theological aesthetics in Thomas's philosophical aesthetics; however, Balthasar (inexplicably, some would say at this point) thinks this could only be done "witn uncertain success" (GL II, 21). One reason for the frequent allusiveness of Balthasar's objections to Aquinas is a second reason for bothering with Balthasar's use of Aquinas: in and with the firmness of Balthasar 's criticisms of Aquinas, the vast majority of Balthasar's uses of Aquinas are constructive rather than critical. Indeed, if taking the measure of theological disputation were primarily a matter of weighing quotations, it could easily be shown that Balthasar's use of Aquinas is by far more positive than negative. More importantly, I shall propose that Balthasar notices features of Aquinas's theology not often noted (or still not noted often enough) by many students of Aquinas. This common ground between Balthasar and Aquinas recalls how, among Roman Catholics in the first part of this century, there was a sort of alliance among Catholic reformers-over against strains of Catholic traditionalisms-between some forms of Thomism and TD= Theodramatik, 4 vols.

Speakers often do not state requests directly but employ innuendos such as Would you like to see my etchings? Though such indirectness seems puzzlingly inefficient, it can be explained by a theory of the strategic speaker, who seeks plausible deniability when he or she is uncertain of whether the hearer is cooperative or antagonistic. A paradigm case is bribing a policeman who may be corrupt or honest: A veiled bribe may be accepted by the former and ignored by the latter. (...) Everyday social interactions can have a similar payoff structure (with emotional rather than legal penalties) whenever a request is implicitly forbidden by the relational model holding between speaker and hearer (e.g., bribing an honest maitre d’, where the reciprocity of the bribe clashes with his authority). Even when a hearer’s willingness is known, indirect speech offers higher-order plausible deniability by preempting certainty, gossip, and common knowledge of the request. In supporting experiments, participants judged the intentions and reactions of characters in scenarios that involved fraught requests varying in politeness and directness. (shrink)

This article re-examines the anthropological scholarship of Sir Arthur Keith (1866–1955), who served as the president of the Royal Anthropological Institute (1914–1917), the Royal Anatomical Society (1918), and the British Association of the Advancement of Science (1927), who wrote prolifically on anatomy, evolution, and the idea of race. While most commonly associated with the Piltdown man hoax, Keith's contributions to the discipline were far greater and more complex. This essay specifically considers how Keith sought to problematize the concept of the (...) nation, considering the nation-state as an evolutionary unit. The first half of this essay examines Keith's theories on the mechanism of evolution (hormonal instincts) and how this informed his ideas of races and nations as evolutionary units. The second half of the essay considers how Keith deployed his ideas about evolutionary instincts, with the goal of advising Britons about how an evolutionary perspective would help understand, if not resolve, modern political challenges, both international and domestic, that faced the British Empire around the time of the First World War.

As a contribution to the Common Knowledge symposium “Whatever Happened to Richard Rorty?,” this essay elucidates how Isabelle Stengers's signature idea of an “ecology of practices” offers a way to establish claims to expertise and—within limits that are, in effect, the limits of specific scientific practices—claims of authority within science that Rorty would have denied. The problems facing Rorty's understanding of science also imperil his vision of a society admirably seeking to realize what he calls “social hope.” Once again, Stengers's (...) ecology of practices, together with her cosmopolitical perspective, offers grounds for questioning Rorty's utopian belief that endless conversation should lead to continual expansion of the “we” who constitute liberal society. Her idea also provides tools for engaging, in mutually respectful and sensitive encounters that reopen prospects for social hope, the multiplicity of voices, perspectives, and practices of the “others” who have been excluded from liberal society.

Abstract:As a flagship program of the New Deal, the CCC was one of several federal agencies which turned to the natural and built environment to promote socio-cultural homogenization between the First and Second World War. This article investigates the CCC's role as an agent of national transformation and considers the links between the New Deal's treatment of the American landscape and its promotion of a new, more pluralistic national identity. While historians of the interwar United States are quick to note (...) the social and environmental significance of the CCC, the cultural role of this program remains largely overlooked. Specifically, relevant scholarship has neglected to address the architectural output of this program and the way it related to the New Deal's broader socio-cultural initiatives. With camps in each of the forty-eight states and overseas territories, the CCC reconfigured much of the American landscape and deployed a regionally diverse blend of vernacular architecture, all while fostering a mythologized sense of cultural heritage from coast to coast. In order to better understand both the role and rationale behind this process, this article considers several examples of CCC-produced architecture and landscape design across the greater United States. It argues that these designs were key vehicles of the unifying message that drove the New Deal and its many so-called ‘alphabet agencies’ from the depths of economic depression to a state of preparedness as the country approached the precipice of global war. This article also considers the Corps' role in the New Deal's construction of popular historical consciousness and draws attention to the frequent transregional interactions between enrollees and local populations.

In lieu of an abstract, here is a brief excerpt of the content:A RETURN TO THE SUBJECT: THE THEOLOGICAL SIGNIFICANCE OF CHARLES TAYLOR'S SOURCES OF THE SELF JAMES J.

This paper extends the evolutionary and developmental research model for SIDS presented in previous articles (McKenna 1990a, 1990b). Data from variety of fields were used to show why we should expect human infants to be physiologically responsive in a beneficial way to parental contact, one form of which is parent-infant co-sleeping. It was suggested that on-going sensory exchanges (touch, movement, smell, temperature, etc.) between co-sleeping parent-infant pairs might diminish the chances of an infantile cardiac-respiratory crisis (such as those suspected to (...) occur in some SIDS cases). In this article we review recent epidemiological data and sleep research findings on SIDS to show how they relate to evolutionary and cross-cultural perspectives. Results of a preliminary study of the co-sleeping behavior of mother-infant pairs indicate that, with respect to sleep, arousal, and respiratory patterns, co-sleeping mother-infant pairs affect each other in potentially important ways. We suggest specifically that co-sleeping may shorten periods of consolidated sleep among young infants by causing them to arouse more frequently. Moreover, we suggest that partner-induced arousals might help the infant to confront sleep crises more competently. In the long run, these arousals might prevent the premature emergence of prolonged (adultlike) sleep bouts from which some infants have difficulty arousing—especially during a breathing pause or apnea.

Kant's Religion within the Boundaries of Mere Reason is one of the great modern examinations of religion's meaning, function and impact on human affairs. In this volume, the first complete English-language commentary on the work, James J. DiCenso explains the historical context in which the book appeared, including the importance of Kant's conflict with state censorship. He shows how the Religion addresses crucial Kantian themes such as the relationship between freedom and morality, the human propensity to evil, the status (...) of historical traditions in relation to ethical principles, and the interface between individual ethics and social institutions. The major arguments are clearly and precisely explained, and the themes are highlighted and located within Kant's mature critical philosophy, especially his ethics. The commentary will be valuable for all who are interested in the continuing relevance of religion for contemporary inquiries into ethics, public institutions and religious traditions. (shrink)

I then turn to some of the incredible conceptual and empirical opportunities here; there are so many it’s easy to feel dizzy. (...) In the final section, I predict that the field of emotion will broaden and become more problem focused, and hazard a “top 10” list of hot topics. (shrink)

Emotion regulation has the odd distinction of being a wildly popular construct whose scientific existence is in considerable doubt. In this article, we discuss the confusion about whether emotion generation and emotion regulation can and should be distinguished from one another. We describe a continuum of perspectives on emotion, and highlight how different (often mutually incompatible) perspectives on emotion lead to different views about whether emotion generation and emotion regulation can be usefully distinguished. We argue that making differences in perspective (...) explicit serves the function of allowing researchers with different theoretical commitments to collaborate productively despite seemingly insurmountable differences in terminology and methods.

John Harris argues that opponents of human embryonic stem cell research, Catholics specifically, suffer an inconsistency in their moral thinking, opposing it on the basis that the sacrifice of an embryo is impermissible even for the good of curing disease. They have no objection to natural procreation, however, which results in many early miscarriages. Harris contends that Catholics tacitly endorse these miscarriages as a permissible sacrifice for the good of producing other, healthy children.

Individuals and businesses make numerous payments every day. They sometimes have choices about what forms of payment to make or accept, and at other times are effectively forced to use a particular form. Often there is an asymmetric power relationship between payer and payee that raises the issue of whether one side unfairly exploits the other. Is it unethical exploitation for an employer to pay employees with a fee-laden payroll card over other more convenient forms of payment? Does the fee (...) structure of payment networks such as Visa and MasterCard unfairly exploit merchants? The bitcoin payment system is an ethical as well as technological evolution as it was designed to be an electronic payment system that does not rely upon trust. Can an entire payment system like bitcoin be “evil,” as charged by Krugman? Payment tools as such are ethically neutral, but can be used in an ethical or unethical manner. (shrink)
