The rise and fall of rationality in language.

The surge of post-truth political argumentation suggests that we are living in a special historical period when it comes to the balance between emotion and reasoning. To explore if this is indeed the case, we analyze language in millions of books covering the period from 1850 to 2019 represented in Google nGram data. We show that the use of words associated with rationality, such as "determine" and "conclusion," rose systematically after 1850, while words related to human experience such as "feel" and "believe" declined. This pattern reversed over the past decades, paralleled by a shift from a collectivistic to an individualistic focus as reflected, among other things, by the ratio of singular to plural pronouns such as "I"/"we" and "he"/"they." Interpreting this synchronous sea change in book language remains challenging. However, as we show, the nature of this reversal occurs in fiction as well as nonfiction. Moreover, the pattern of change in the ratio between sentiment and rationality flag words since 1850 also occurs in New York Times articles, suggesting that it is not an artifact of the book corpora we analyzed. Finally, we show that word trends in books parallel trends in corresponding Google search terms, supporting the idea that changes in book language do in part reflect changes in interest. All in all, our results suggest that over the past decades, there has been a marked shift in public interest from the collective to the individual, and from rationality toward emotion.

Engineering History in Latin America: A Review of Spanish-Language Books.

This review essay examines five Spanish-language books published in Latin America on the emergence of engineering in the region. Focusing on a period from roughly 1850 to 1970, these works share themes of foreigners and foreign education, nation-state construction, and social conceptions of prestige. This research suggests that throughout Latin America foreign educators and models were prominent in early engineering programs and enterprises. However, many historians associate the growth of engineering, especially civil engineering, with increasing state consolidation and economic intervention. As social perceptions of the value of professional engineering changed, domestic engineers increasingly became important planners and mediators. Some engineers became state leaders. By contextualizing these works with other scholarship on the history of engineering, this review essay highlights new insights while suggesting the need for greater attention to gender, race, and labor; comparisons between developments in Latin America, Africa, and Asia; and more research on private-sector engineers.

A contextual thematic analysis of the accessory nerve in Scottish historical medical collections of the Royal Colleges of Edinburgh and Glasgow.

INTRODUCTION: The classification of the accessory nerve (CN XI) remains a source of debate; its exact function has not been fully elucidated having also an atypical morphology for a cranial nerve. A better insight into its anatomical and physiological features is of clinical relevance. The aim was to conduct a review of 18th and 19th century books from the Royal Medical/Surgical Colleges in Scotland, United Kingdom. A contextual historical analysis of the depictions and descriptions of the accessory nerve could provide insight into the disparity in the current descriptions. MATERIALS AND METHODS: Online archive catalogues were systematically searched and, during site visits, resources were formally and contextually analyzed, with the information then thematically analyzed. The themes were discussed against a widely known reference textbook of the era. RESULTS: Based on the thematic analysis, the resources were categorized either as practical anatomy books or field-specific anatomy books including neuroanatomy atlases. This intended use, along with the target audience, influenced the scope and detail of information, typically with general anatomy for students in the practical resources, and specialist information in the field-specific resources. The authors' professional background also influenced the way the accessory nerve was described and/or depicted, with surgeons/physicians placing emphasis on the clinical aspects. Content variations could also be attributed to communication restrictions of the era, and associated purchasing costs. CONCLUSIONS: Although scientific advances are nowadays disseminated at a faster pace, actively bridging the gap between anatomical sciences and clinical research is still needed when considering the accessory nerve to further elucidate the mysteries of this structure.

"Not Just for Doctors Anymore": How the Merck Manual Became a Consumer Health "Bible".

The transformation of the Merck Manual of Diagnosis and Therapy from a "doctors-only" reference into a consumer health bible illuminates a critical era in the history of the twentieth-century medical book. Merck and Company restricted sales of its Merck Manual, first published in 1899 to offer up-to-date information for the busy practitioner, to physicians and other health care professionals until the 1970s. As more laypeople sought to get involved in their own health care decision making, the Merck Manual developed a devoted following. In the late 1980s, with almost a quarter of its sales going to nonphysicians, Merck and Company decided to put out a home edition of its famous manual. This evolution provides important insights into both the history of the medical book and the doctor-patient relationship in the United States.

Darwin's perception of nature and the question of disenchantment: a semantic analysis across the six editions of On the Origin of Species.

This body of work is motivated by an apparent contradiction between, on the one hand, Darwin's testimony in his autobiographical text about a supposed perceptual colour blindness before the aesthetic magnificence of natural landscapes, and, on the other hand, the last paragraph of On the Origin of Species, where he claims to perceive the forms of nature as beautiful and wonderful. My aim is to delve into the essence of the Darwinian perception of beauty in the context of the Weberian concept of "disenchantment of the world", assumed as a possible conceptual axis that enables the unravelling of the core of this contrast of perceptions. In acknowledging the theory of evolution as one of the most prominent scientific theories likely to have contributed to disenchantment, a number of questions arise: Is disenchantment compatible with aesthetic experience and sensibility before natural beauty? Was it Darwin's disenchanted conception of the world that led him to believe he was colour blind? To answer these questions, a computer-assisted semantic analysis of lexical frequency and variability, most especially focused on aesthetic-emotional and religious or spiritual adverbs and adjectives, has been undertaken across the six editions of The Origin. The semantic analysis demonstrates that, although disenchanted, Darwin's descriptions of, mainly, the adaptational excellence of living beings, reflect an aesthetically enriched perception of nature. It is concluded that Darwin's perceptual colour blindness, then, might be based on a confusion rooted in the equation of equality between aesthetic sensibility in nature and the perception of its beauty as part of the vestigia Dei.

Ateleological propagation in Goethe's Metamorphosis of plants.

It was commonly accepted in Goethe's time that plants were equipped both to propagate themselves and to play a certain role in the natural economy as a result of God's beneficent and providential design. Goethe's identification of sexual propagation as the "summit of nature" in The Metamorphosis of Plants (1790) might suggest that he, too, drew strongly from this theological-metaphysical tradition that had given rise to Christian Wolff's science of teleology. Goethe, however, portrayed nature as inherently active and propagative, itself improvising into the future by multiple means, with no extrinsically pre-ordained goal or fixed end-point. Rooted in the nature philosophy of his friend and mentor Herder, Goethe's plants exhibit their own historically and environmentally conditioned drives and directionality in The Metamorphosis of Plants. In this paper I argue that conceiving of nature as active productivity-not merely a passive product-freed Goethe of the need to tie plants' forms and functions to a divine system of ends, and allowed him to consider possibilities for plants, and for nature, beyond the walls of teleology.

Moreau de Tours: organicism and subjectivity. Part 1: Life and work.

This is the first of two articles analysing the importance of J.J. Moreau de Tours' work and its influence on the development of descriptive psychopathology from the mid-nineteenth century to the present. Part 1 focuses on biographical aspects and presents Moreau's main works in their social and cultural context, with special emphasis on his book Du Hachisch et de l'Aliénation mentale, published in 1845. The second article will concentrate on Moreau as a psychopathologist.

Margiad Evans (1909-1958): A writer's epileptic experiences and their reflections in her work.

Margiad Evans, in the period 1930-1950, an acclaimed English writer, developed convulsive seizures at age 41 and died at age 50 from the tumor that had caused them. In her book "A Ray of Darkness", she describes in profound analytic detail her seizure experiences, especially the isolated auras that had preceded her first convulsion by many years. Their ultimate strangeness echoed a long-standing fascination by the indescribable, which is a recurrent theme in her literary work. Another aspect of her poetry, a focus on the experience of the moment that cannot be retained is likewise reminiscent of the volatility of her aura experiences. Of three texts that are presently being published posthumously, one ("The Nightingale Silenced") is a fragmentary continuation of her epileptic experience. She considered that she still had a lot to describe, contributing the inside of the "outside inside story" of epilepsy, clues on which neurology could work to obtain a deeper understanding. To have a focal motor seizure feels like being invaded by an alien force. An urge to run and heautoscopy are other recorded symptoms. Evans documents the experience of a long-lasting, predominantly nonconvulsive status epilepticus merging into aura continua where her earlier aura experiences appear transformed into a quasipsychotic state. But even in the account of "this appalling, this hellish condition", she is careful to maintain her high literary standards. Together, the two reports on her disease seem to represent the only comprehensive inside case history of epilepsy, a most valuable legacy.

Medicinal plants containing pyrrolizidine alkaloids in the New Kreuterbuch by Leonhart Fuchs (1543).

In mid-16 th century, three scientific books have been edited, which have been a real sensation, each one in its own scientific field. The first one, published in Nürnberg by Nikolaus Kopernikus, named: "De Revolutionibus Orbium Celestium Libri VI" put the sun in the center of the universe, and takes the human being out of the middle of the world. The second one, published in Basel by Andreas Vesalius: "De Humani Corporis Fabrica", describes the anatomy of the human body and the third one, also published in Basel by Leonhart Fuchs, was named "New Kreuterbuch". It shows woodcuts of the most important medicinal plants of its time along with botanical descriptions and therapeutic uses. This book emerged as one of the most influential botanical works of the 16 th century and is still interesting. Here, we used it to investigate which medicinal plants of the Early Modern times contained pyrrolizidine alkaloids. In total, 15 species were identified.

[Psychiatric textbooks from National Socialism and the censorial practice in the Soviet Occupation Zone and early GDR]. / Psychiatrische Fachbücher aus dem Nationalsozialismus und die zensorische Praxis in der SBZ und frühen DDR.

The Allied Forces policy of denazification and demilitarization during the early post-war period has had a lasting impact on medical disciplinary cultures in all occupation zones of Germany. By means of various control procedures, the conceptuality and linguistic design, the style and normative horizon of medical literature were reconstituted. This article examines this change using the example of psychiatry and neurology in the Soviet Occupation Zone. It deals with the neurological psychiatric textbook as a central medium of disciplinary communication and reconstructs how the knowledge in this field was processed and prepared in complex negotiation processes between authors, publishers and censors. The focus is on institutionalized filters of limited production of discourses and thus the archival holdings of censorship authorities, which have not yet been evaluated. The evaluation results are presented here with a focus on psychiatry and neurology and illustrated with selected case studies.

Foucault's Folie et déraison: its influence and its contemporary relevance.

Michel Foucault remains one of the most influential intellectuals in the early twenty-first century world. This paper examines the origins and impact of his first major work, Folie et déraison, on the history of psychiatry, particularly though not exclusively in the world of Anglo-American scholarship. The impact and limits of Foucault's work on the author's own contributions to the history of psychiatry are examined, as is the larger influence of Madness and Civilization (as it is known to most Anglophones) on the nascent social history of psychiatry. The paper concludes with an assessment of the sources of the appeal of Foucault's work among some scholars, and notes his declining influence on contemporary scholars working on the history of psychiatry.

Francis Bacon, José de Acosta, and Traditions of Natural Histories of Winds.

It is well attested that Francis Bacon considered his History of Winds to be an exemplar, but what lessons should be taken from its example have been subject to debate. Instead of looking at this work as a mere model for the fusion of natural history and natural philosophy, it is also possible to see Bacon as trying to provide tentative solutions to outstanding questions regarding the wind, a topic that was deeply scrutinized during the early modern period. An examination of Bacon's provisional concluding rules reveals deep correspondences with earlier works, such as José de Acosta's Natural and Moral History of the Indies, that revised classical understandings of the wind based on experience, experiments, and accounts of travels beyond Europe. Understanding the History of Winds as a genuine attempt to solve outstanding questions about the wind uncovers its debt to earlier traditions, including those related to Renaissance natural history, and shows it's influence in relation to specific theories of the wind beyond its call for methodological reform.

'Ghosts from other planets': plurality of worlds, afterlife and satire in Emanuel Swedenborg's De Telluribus in mundo nostro solari (1758).

In 1758 in London, Swedish natural philosopher and mystic theologian Emanuel Swedenborg published De Telluribus in Mundo nostro Solari (Earths in our solar system), a treatise on the plurality of worlds and life on other planets. During the seventeenth and eighteenth centuries, these topics formed a heterogenous literary genre which encompassed theology, astronomy, philosophy and satire. In De Telluribus, Swedenborg made detailed claims of communication with extraterrestrial spirits in the afterlife, through which he sought to spread his theology to new audiences. The paper will explore the role of De Telluribus in Swedenborg's career, explain its content and analyse its polarized reception. It will show that De Telluribus combined for the first time the literary codes of two popular genres during the period, namely those concerning the plurality of worlds and the dialogues of the dead. By doing so, the paper revises current scholarly understanding of Swedenborg by showcasing him as a versatile yet ill-fated recombiner of literary genres. More broadly, the paper will shed light upon previously unnoticed eighteenth-century literary interactions along with a wider overview on the reception of themes such as the plurality of worlds, mysticism and satire in Scandinavia and Germany.

Il n'y a pas d'amour heureux pour Casanova: Chemical- and bio-analysis of his Memoirs.

The original manuscript of Casanova's Memoirs is stored at the Bibliothèque Nationale de France in Paris. We have gained access to it and explored the surfaces of chapters one and two (via the ethylene vinyl acetate [EVA] film technology, i.e., of diskettes of ethylene vinyl acetate with embedded strong cation and anion exchangers and C8 resins) in search of potential diseases of the author, especially of the gonorrhea bacterium, since Casanova reported that he had several bouts of this pathology along his adventurous life. Although the bacterium was not found, we have detected high levels of HgS as red spots along the lines of the manuscript, suggesting that Casanova was using this chemical as a cure for his venereal disease. Additionally, among the several bacteria identified on the surface via mass spectrometry, we could detect traces of Streptococcus uberis, a typical animal infection, found also in humans, together with a few strains of Lactobacilli, probably present in his saliva. The EVA film technology appears to open new horizons for investigating the world Cultural Heritage.

Antoine Ferrein (1693-1769)-His Life and Contribution to Anatomy and Physiology: The Description of the Vocal Chords and Their Function.

The purpose of this study is to summarize the life and work of the French anatomist and surgeon Antoine Ferrein (1693-1769). Ferrein made an impact in the history of anatomy and physiology through his work and especially with the description of phonation, renal anatomy, and liver and biliary structure. He also made an impact on ophthalmology with the description of the eyelid and its diseases. After a thorough review of the literature, we present in this review his life and his main discoveries with special emphasis on the anatomic description of the vocal chords resembling the chords of a violin tempered by the air exhaled from the lungs and how the physiology of phonation and the surgery of the larynx were revolutionized after that.

[Origin and development of the book Medical Semiology]. / Sobre el origen y desarrollo del libro Semiologia Médica.

Semiotics and Semiology share a similar etymology and meaning: the study of signs. In Medicine, signs are objective manifestations of disease, as opposed to the subjective nature of symptoms. Medical semiology comprises the study of symptoms, somatic signs and laboratory signs, history taking and physical examination (in English-speaking countries is known as Bedside diagnostic examination or Physical diagnosis). The first edition of Medical Semiology dates from 1987, and new editions appeared in 1999, 2010, and 2017. The book is devoted to semiology proper with clinical orientation. Its origin, however, dates back to 1937, when the University of Chile appointed Dr. Hernán Alessandri (1900-1981), the eminent Chilean medical educator, Professor in Semiology at the Internal Medicine Section of the Hospital del Salvador in Santiago. The authors of the present book served as Dr. Alessandri's teaching assistants for decades. The two-semester course in semiology had a tutorial character: each teaching assistant was assigned five students whom engaged daily in practical activities in the hospital wards for a total of four hours, in addition to a 45- minute lecture on the theoretical aspects of the subject. The 720-page fourth edition of the book brings together teaching method and clinical experience of more than 50 years. The book consists of six Sections: "Cardinal manifestations of disease", "Major clinical syndromes", "History taking and Physical examination", "Clinical diagnosis and the patient-physician relationship", "Laboratory clinical tests and Instrumental exploration of the body," and "Glossary of diseases." In its forty Chapters, a total of 207 issues are described in detail.

Final chapter, From India to the Planet Mars: A Study of a Case of Somnambulism with Glossolalia, by Théodore Flournoy (1900).

Among the many attempts to explain mediumship psychologically at the turn of the century were the efforts of Swiss psychologist Théodore Flournoy (1854-1920). In his well-known book Des Indes à la Planète Mars (1900), translated as From India to the Planet Mars (1900), Flournoy analysed the mediumistic productions of medium Hélène Smith (1861-1929), consisting of accounts of previous lives in France and in India, and material about planet Mars. Flournoy explained the phenomena as a function of cryptomnesia, suggestive influences, and subconscious creativity, analyses that influenced both psychology and psychical research. The purpose of this Classic Text is to reprint the conclusion of Flournoy's study, whose ideas were developed in the context of psychological attention to mediumship and secondary personalities.

Love and loss in wartime: An unpublished narrative by Pamela Frankau (1908-67).

This article discusses an unpublished book by the popular and prolific novelist Pamela Frankau (1908-67), which was rejected by her publishers in 1946 as "almost too personal for publication," and which for many years was believed lost. The work is addressed to Frankau's dead lover, Marjorie Vernon Whitefoord (1907-44), a fellow officer in the women's Auxiliary Territorial Service, and takes the form of a letter to Vernon. The article examines what Frankau's unpublished narrative of love and loss in wartime reveals about her life and later novels, and its implications for the official record of her life and writing.
