The periodic system arose from knowledge about substances, which constitute the chemical space. Despite the importance of this interplay, little is known about how the expanding space affected the system. Here we show, by analysing the space between 1800 and 1869, how the periodic system evolved until its formulation. We found that after an unstable period culminating around 1826, the system began to converge to a backbone structure, unveiled in the 1860s, which was clearly evident in the 1840s. Hence, contrary to the belief that the ``ripe moment'' to formulate the system was in the 1860s, it was in the 1840s. The evolution of the system is marked by the rise of organic chemistry in the first quarter of the nineteenth-century, which prompted the recognition of relationships among main group elements and obscured some of transition metals, which explains why the formulators of the periodic system struggled accommodating them. We also introduced an algorithm to adjust the chemical space according to different sets of atomic weights, which allowed for estimating the resulting periodic systems of chemists using one or the other nineteenth-century atomic weights. These weights produce orderings of the elements very similar to that of 1869, while providing different similarity relationships among the elements, therefore producing different periodic systems. By analysing these systems, from Dalton up to Mendeleev, we found that Gmelin's atomic weights of 1843 produce systems remarkably similar to that of 1869, a similarity that was reinforced by the atomic weights on the years to come.

The reception of Mendeleev’s periodic system in Sweden was not a dramatic episode. The system was accepted almost without discussion, but at the same time with no exclamation marks or any other outbursts of enthusiasm. There are but a few weak short-lived critical remarks. That was all. I will argue that the acceptance of the system had no overwhelming effect on chemical practice in Sweden. At most, it strengthened its characteristics. It is actually possible to argue that chemistry in Sweden was more essential for the periodic system than the other way around. My results might therefore suggest that we perhaps have to reevaluate the role of Mendeleev’s system in the history of chemistry. Chemistry in Sweden at the end of the nineteenth century can be characterized as a classifying science, with chemists very skilled in analysis, and as mainly an atheoretical science, which treated theories at most only as hypothesis—the slogan of many chemists being “facts persist, theories vanish.” Thanks to these characteristics, by the end of the nineteenth century, chemistry in Sweden had developed into, it must be said, a rather boring chemistry. This is obviously not to say that it is boring to study such a chemistry. Rather, it gives us an example of how everyday science, a part of science too often neglected but a part that constitutes the bulk of all science done, is carried out. One purpose of this study is to see how a theory, considered to be important in the history of chemistry, influenced everyday science. One might ask what happened when a daring chemistry met a boring chemistry. What happened when a theory, which had been created by a chemist who has been described as “not a laboratory chemist,” met an atheoretical experimental science of hard laboratory work and, as was said, the establishment of facts? Furthermore, could we learn something about the role of the periodic system per se from the study of such a meeting? Mendeleev’s system has often been considered important for teaching, and his attempts to write a textbook are often taken as the initial step in the chain of thoughts that led to the periodic system.

Although periodic systems were produced independently by six codiscoverers in the space of a decade, Dmitri Mendeleev’s system is the one that has had the greatest impact by far. Not only was Mendeleev’s system more complete than the others, but he also worked much harder and longer for its acceptance. He also went much further than the other codiscoverers in publicly demonstrating the validity of his system by using it to predict the existence of a number of hitherto unknown elements. According to the popular story, it was Mendeleev’s many successful predictions that were directly responsible for the widespread acceptance of the periodic system, while his competitors either failed to make predictions or did so in a rather feeble manner. Several of his predictions were indeed widely celebrated, especially those of the elements germanium, gallium, and scandium, and many historians have argued that it was such spectacular feats that assured the acceptance of Mendeleev’s periodic system by the scientific community. The notion that scientific theories are accepted primarily if they make successful predictions seems to be rather well ingrained into scientific culture, and the history of the periodic table has been one of the episodes through which this notion has been propagated. However, philosophers and some scientists have long debated the extent to which predictions influence the acceptance of scientific theories, and it is by no means a foregone conclusion that successful predictions are more telling than other factors. In looking closely at the bulk of Mendeleev’s predictions in this chapter, it becomes clear that, at best, only half of them proved to be correct. This raises a number of questions. First of all, why is it that history has been so kind to Mendeleev as a maker of predictions? As historian of chemistry William Brock has pointed out, “Not all of Mendeleev’s predictions had such a happy outcome; like astrologers’ failures, they are commonly forgotten.”

The Ring, though many years in gestation (1848-74), was essentially the fruit of Wagner’s politically most radical anarchist period concurrent with and immediately following the mid-century revolts. The nineteenth century was obsessed by the Myth of Revolution, the myth that was one of that century’s two most baleful legacies to the one that followed (the other one was the Myth of Nation). In Wagner’s tetralogy this obsession found its arguably grandest artistic expression. Inspired by Feuerbach, Proudhon, and Bakunin, it is a poem intoxicated by the orgy of destruction of the old world in which humans compete for power and riches and by the hopeful anticipation of the world to come, the world of spontaneous solidarity and love—an anarchist utopia.

Superficial resemblances between George Herbert's The Temple and John Keble's The Christian Year are too obvious to escape notice. Both emanated from little country parsonages, one at Bemerton, near Salisbury, the other at Hursley, five miles from Winchester, or possibly in part at Fairford in the Oxford region. Neither author intended his work for immediate publication. “Deliver this little book,” said Herbert, “to my dear brother Ferrar, and tell him he shall find in it a picture of the many spiritual conflicts that have passed betwixt God and my soul, before I could subject mine to the will of Jesus my Master.” With the same modest self-effacement Keble planned, as one of his friends testified, “to go on improving the series all his life, and leave it to come out, if judged useful, only when he should be fairly out of the way.” Each book, furthermore, was written when clouds had gathered thick about the Church, and possibly the rationalizing temper of the nineteenth century was a more insidious foe than the stiff-necked Puritanism of the seventeenth. Inevitably, these two collections of sacred poems, the finest poetical expression of the Anglican Church, have been linked together.

Over Time

Although racial lines eventually hardened on both sides, in the opening decades of colonization European and native ideas about differences between themselves and the other were fluid and dynamic, changing on the ground in response to local developments and experiences. Over time, perceived differences were understood to be rooted in more than just environment and culture. In the eighteenth century, bodily differences became the basis for a wider range of deeper, more innate distinctions that, by the nineteenth century, hardened into what we might now understand to be racialized differences in the modern sense. Despite several centuries of dispossession, disease, warfare, and enslavement at the hands of Europeans, native peoples in the Americans almost universally believed the opposite to be true. The more indigenous Americans were exposed to Europeans, the more they believed in the vitality and superiority of their own cultures.

The phenomenon and ethics of “voting” will be explored in the context of human enhancements. “Voting” will be examined for enhanced humans with moderate and extreme enhancements. Existing patterns of discrimination in voting around the globe could continue substantially “as is” for those with moderate enhancements. For extreme enhancements, voting rights could be challenged if the very humanity of the enhanced was in doubt. Humans who were not enhanced could also be disenfranchised if certain enhancements become prevalent. Voting will be examined using a theory of engagement articulated by Professor Sophie Loidolt that emphasizes the importance of legitimization and justification by “facing the appeal of the other” to determine what is “right” from a phenomenological first-person perspective. Seeking inspiration from the Universal Declaration of Human Rights (UDHR) of 1948, voting rights and responsibilities will be re-framed from a foundational working hypothesis that all enhanced and non-enhanced humans should have a right to vote directly. Representative voting will be considered as an admittedly imperfect alternative or additional option. The framework in which voting occurs, as well as the processes, temporal cadence, and role of voting, requires the participation from as diverse a group of humans as possible. Voting rights delivered by fiat to enhanced or non-enhanced humans who were excluded from participation in the design and ratification of the governance structure is not legitimate. Applying and extending Loidolt’s framework, we must recognize the urgency that demands the impossible, with openness to that universality in progress (or universality to come) that keeps being constituted from the outside.

Abstract In nineteenth-century France, liberals assumed that a conservative judiciary was frequently biased in favour of the prosecution, and socialists assumed that juries were dominated by the upper classes and too unrepresentative of the population to render justice equitably. Agitation by the left to combat these perceived biases led to the adoption of two key reforms of the fin de siècle. One was the abolition in 1881 of the résumé, or summing-up of the case by the chief justice of the cour d’assises (felony court). Liberals thought this reform was necessary because judges allegedly often used the résumé to persuade jurors in favour of conviction, a charge repeated by modern historians. The other reform, beginning at about the same time, was to make jury composition more democratic. By 1880, newly empowered liberals (at least in Paris) had begun to reduce the proportion of wealthy men on jury lists. This was followed in 1908 by the implementation of a circular issued by the Minister of Justice ordering the jury commissions to inscribe working-class men on the annual jury lists. However, a quantitative analysis of jury verdicts suggests that the reforms of the early 1880s and 1908 had only modest impacts on jury verdicts. Ideas and attitudes seem to have been more important. This has implications regarding two key controversies among modern jurists: the extent to which judges influence jurors and the extent to which the characteristics of jurors influence their verdicts.

A recent article of Leon Livingstone rightly calls attention to the importance of Pérez Galdós' assimilation of Cervantine irony as a forerunner of the concern of modern Spanish novelists about the autonomy of their characters. The unreality of rationalism, which Livingstone holds to be the germ of El amigo Manso, the imagination's capacity to create reality at the heart of Misericordia, lead to the even bolder experiments in the artistic representation of reality undertaken by Unamuno, Azorín, Valle-Inclán, and Pérez de Ayala. Anomalous for his time yet so pervasive in his work is Galdós' employment of “interior duplication” that a separate study would contribute to our fuller understanding of his art as well as to our measure of the advances in the Spanish novel of the latter half of the nineteenth century. The present essay focuses on Galdós' developing skill with internal repetitions from La Fontana de Oro (publ. 1870), through the rich complexities of the novels written between 1886–89, to their almost stylized simplicity in El abuelo (1897). Always related to Cervantine irony, the variety of verbal echoes, the mirroring of one character in another, the unconscious illumination each may offer the other, underscore the increasingly intimate wedding of form and matter with which Galdós came to unfold his narratives.
