Hearts which, at first sight, seem to have a solitary chamber within their ventricular mass have long been the subject of controversy. As difficult as it is to manage these cardiac malformations medically and surgically, it has been at least as challenging, to date, merely to describe and classify them. Even the most commonly used terms, “single ventricle” and “univentricular heart”, spark heated debate. In distant times, when congenitally malformed hearts were pathological curiosities, these entities were described as “cor triloculare biatriale”. Therein lies the beginning of the problem, since when hearts of this type were examined by more enlightened pathologists, such as the great Maude Abbott,1it became plain that the apparently solitary ventricular mass in reality possessed a second, albeit much smaller, chamber. Abbott described this second structure as the “outlet chamber”. This convention of describing a “single ventricle”, albeit with a co-existing “outlet chamber”, that presumably lacked ventricular status, continued throughout the first half of the twentieth century, although it had been recognised by then that hearts could rarely be found with truly solitary ventricles, and these were typically deemed to be common structures. Van Praagh et al.2neatly summarised the problem with this approach when they pointed out that the so-called “single ventricle” possessed two ventricular chambers, whilst the “common ventricle” described the truly solitary arrangement. In their seminal investigation of 1964, Van Praagh et al.2analysed only those hearts unified because of double inlet atrioventricular connection, or alignment. They excluded arbitrarily from their investigation all hearts with atrioventricular valvar atresia, despite the similarity in morphology between many of these latter lesions and the hearts with double inlet.3

Beginning in 1834, entomologists across Europe began reporting same-sex copulatory activity in a variety of insect species, sometimes between species or genera. Most communications concerned male-male couplings of the common cockchafer (Melolontha melolontha, syn. M. vulgaris). These reports offer a unique snapshot of how nineteenth-century naturalists responded when they were required to explain precisely what was natural in their observations. Initial communications of same-sex couplings were mainly accompanied by exclamations of surprise and the rhetoric of disapproval. Such activity was explained either by the assumption that one of the parties must in some way have a female anatomy or that blind or excessive lust compelled more virile individuals to force copulation upon weaker ones. As these explanations were questioned, more complex and controversial theories founded in fashionable evolutionary theories were forwarded as means of assimilating the phenomenon within hegemonic constructions of sexuality. These came from both within entomological circles and from outside observers whose primary interest was in theorizing human eroticism. This article follows a particularly intense dispute which erupted following the claim by one of France's leading naturalists, Henri Gadeau de Kerville, that the homoerotic activity demonstrated by male cockchafers evidenced the existence of a distinctly “homosexual” instinct. By 1900 no single taxonomy of non-human homoeroticism dominated intellectual discourse on the subject. Although zoological observations of same-sex eroticism continued to be made through the twentieth century, Melolontha were left in relative peace.

A study was made of the pathologic anatomy in 147 cases of complete transposition of the arterial trunks. A classification was attempted, dependent upon the extent and nature of ventricular septation and the presence or absence of abnormalities in the atrioventricular orifices. Complete transposition with mitral stenosis or atresia or with common atrioventricular orifice are characteristically associated with pulmonic stenosis and atresia, while complete transposition with tricuspid stenosis or atresia, or with common ventricle, or single ventricle and small outlet chamber are more commonly associated with increased pulmonary flow. The two complexes, complete transposition with common ventricle and that with single ventricle and small outlet chamber, are very closely related pathologically.

Abstract For centuries, the question whether there were peoples without religion was the subject of heated debate among European thinkers. At the turn of the twentieth century, this concern vanished from the radar of Western scholarship: all known peoples and societies, it was concluded, had some form of religion. This essay examines the relevant debates from the sixteenth to the twentieth century: Why was this issue so important? How did European thinkers determine whether or not some people had religion? What allowed them to close this debate? It will be shown that European descriptions of the “religions” of non-Western cultures counted as evidence for or against theoretical claims made within a particular framework, namely that of generic Christian theology. The issue of the universality of religion was settled not by scientific research but by making ad hoc modifications to this theological framework whenever it faced empirical anomalies. This is important today, because the debate concerning the cultural universality of religion has been reopened. On the one hand, evolutionary-biological explanations of religion claim that religion must be a cultural universal, since its origin lies in the evolution of the human species; on the other hand, authors suggest that religion is not a cultural universal, because many of the “religions” of humanity are fictitious entities created within an underlying theological framework.

ABSTRACTRecent research on twentieth-century Africa has been marked by a surge of interest in autobiographical narrative. While this development is generally praiseworthy, the knowledge it has produced has been uneven, in temporal as well as spatial terms. This article channels the current interest in personal experience and narrative to a place and time where resonances of the ‘common’ voice have been rather weak: the Republic of Guinea, across the final decades of the twentieth century. Foregrounding the autobiographical reflections of a local teacher in the country's southeastern forest region, it forges new perspectives on political subjectivity in Guinea's understudied provinces.

The love affair which has a title part in the Rape of the Lock was perhaps once so obvious as to need no comment; at least Dr. Johnson thought “the subject of the poem … an event below the common incidents of common life.” By the twentieth century the love story seemed so obscure as to defy analysis; at least Geoffrey Tillotson thought that the rejection of the hero by the heroine was unaccountable. A decade ago Cleanth Brooks refurbished the action as a neo-classic campaign in the unending “war of the sexes” over rites of possession. Some such pattern of pre-marital courtship is doubtless a norm assumed for the comedy of the poem, as it is—William K. Wimsatt reminds us—for Molière's Misanthrope, Congreve's Way of the World, and Meredith's Egoist. While suggestively approaching the plan of the action, however, Brooks has rather too closely assimilated Pope's particular campaign to the general war. If the comedy of the poem posits a norm, it also sets forth a divergence. One is free to speculate that in a hypothetical sequel to Pope's poem the Baron and Belinda might have gone on (like other gallivanting young people, indeed like Arabella Fermor and Lord Petre) to get married—he to another woman, she to another man. But as it stands the poem is not directly concerned with what Brooks calls “the elaborate and courtly conventions under which Belinda fulfills her natural function of finding a mate” (p. 84). Both Belinda and the Baron are at the age of exuberance where the armor of courtship fits rather loosely, like the helmet Swift stuck on Dryden. Feigning “death,” sophisticating love, and shunning marriage, they wage a mock war in a mock-heroic poem. Their maneuvers, I wish to show, make the plot of the poem a contest of wiles between commanding personalities—an uninhibited philanderer and an invincible flirt.

With the recent four hundredth anniversary of the sailing of the Spanish Armada came a virtual flood of new works concerning the great invasion fleet and the English ships that opposed it. While it would seem that there would be little new to say about such a heavily researched subject, there is one aspect of this momentous year that has been received relatively short shrift by historians of the period, the national mobilization of England to meet the threatened invasion. Often referred to as the Great Muster of 1588 because one of its most important elements was the muster of the militia to fill the ranks of the army, it was an administrative feat of massive scope that involved months of preparation, extensive military planning, and precise timing. Because these arrangements were never tested in battle, however, the effectiveness of this effort is hard to judge, and its importance is often missed by historians. While Garrett Mattingly devoted an entire chapter of his well known work on the Armada year to events on land, he found the queen's visit to the army at Tilbury after the departure of the Armada more important, or at least more interesting, than the actual state of the nation's defense. More recently, Geoffrey Parker has used the discovery of a large quantity of siege equipment on an excavated armada wreck as a jumping off point for his article “If The Armada Had Landed.” Approaching the issue from the standpoint of a historian of the Army of Flanders, and leaning heavily on continental sources, he adheres to the view that England was totally unprepared for fighting on land if the Spanish had succeeded in landing troops on the island. While this view reflects the common opinion of both nineteenthand twentieth-century historians on the subject, a careful review of English sources, particularly the surviving muster records, military papers, and coastal surveys, leaves a good deal of doubt concerning the accuracy of Parker's judgment. It is the purpose of this article to examine the English side of the story of the Great Muster of 1588, by illustrating the extensive defensive preparations that were organized to face the Spanish threat.

<p>The article contributes to the study of implementation of the genre traditions of the Russian Medieval literature in the prose of the second half of the twentieth century, specifies categorical coordinates and challenges research approaches, artificially separating a single movement of Russian literature from the time of Ilarion and Avvakum to the present day. On the example of V.&nbsp;P.&nbsp;Astafiev&rsquo;s book &ldquo;Zatesi&rdquo; which united the writer's small prose on the principle of cyclization of works based on the common stylistic and thematic features, the author comes to the conclusion about the artistic relevance of this technique, which originates in the medieval collections, in the aspiration of their compilers to work &ldquo;outside of genre traditions&rdquo; (D.&nbsp;S.&nbsp;Likhachev). But if in the Middle Ages this aspiration is more due to the subject-thematic tasks, in the New and Modern times the super-genre unity of the collection, of the book is a&nbsp;result of strengthening the compositional role of the author in their structural organization and the individualization of his image.</p>

Regarded by many as the pre-eminent Islamicist of the twentieth century, Henry Corbin is also the subject of much criticism, aimed primarily at his supposed overemphasis on the mythological aspects of Islamic philosophy and his idiosyncratic privileging of the concept of the imaginal world. Taking seriously an unusual claim made by Steven Wasserstrom in Religion after Religion that the redeployment of Schelling's concept of tautegory by Corbin reveals all that is wrong with his work, this essay seeks to defend both the concept and Corbin's use of it. Developed by Schelling in his late work on mythology, the concept of tautegory turns out to be, for historical and theoretical reasons, a revelatory switch point. Not only does it make clear why the imaginal ‘locus’ is key to understanding the unity of God – the oneness of his apophatic and revealed dimensions – it also gives us profound insights into the links connecting Islamic philosophy, German Idealism, and psychoanalysis, which all take their bearings from the esoteric or mystical idea of an unconscious abyss.

Starting with the controversial esoteric employment of audio recordings by followers of the charismatic Muslim preacher Sharif Haidara in Mali, the article explores the dynamics emerging at the interface of different technologies and techniques employed by those engaging the realm of the Divine. I focus attention on the “border zone” between, on the one hand, techniques for appropriating scriptures based on long-standing religious conventions, and, on the other, audio recording technologies, whose adoption not yet established authoritative and standardized forms of practice, thereby generating insecurities and becoming the subject of heated debate. I argue that “recyclage” aptly describes the dynamics of this “border zone” because it captures the ways conventional techniques of accessing the Divine are reassessed and reemployed, by integrating new materials and rituals. Historically, appropriations of the Qur’an for esoteric purposes have been widespread in Muslim West Africa. These esoteric appropriations are at the basis of the considerable continuities, overlaps and crossovers, between scripture-related esoteric practices on one side, and the treatment by Sharif Haidara’s followers of audio taped sermons as vessels of his spiritual power, on the other.

This book offers a new way to understand the divisions that organize twentieth-century poetry. It argues that the most important conflict is not between styles or aesthetic politics, but between poets who seek to preserve or produce the incommensurable particularity of experience by making powerful objects, and poets whose radical commitment to abstract personhood seems altogether incompatible with experience—and with poems. Reading across the apparent gulf that separates traditional and avant-garde poets, the book reveals the common philosophical urgency that lies behind diverse forms of poetic difficulty—from William Butler Yeats's esoteric symbolism and George Oppen's minimalism and silence to Frank O'Hara's joyful slightness and the Language poets' rejection of traditional aesthetic satisfactions. For these poets, what begins as a practical question about the conduct of literary life—what distinguishes a poet or group of poets?—ends up as an ontological inquiry about social life: What is a person and how is a community possible? In the face of the violence and dislocation of the twentieth century, these poets resist their will to mastery, shy away from the sensual richness of their strongest work, and undermine the particularity of their imaginative and moral visions—all in an effort to allow personhood itself to emerge as an undeniable fact making an unrefusable claim.
