According to Hermann von Helmholtz, sensations are signs that external causes impress on our sense organs; those signs are then used by the mind to acquire knowledge of the reality. Helmholtz's work points out the difficulty of defining a notion of causality suitable for explaining the relation between sensations on the one hand and the physical world on the other. In fact, he states that: 1) Physical stimuli, understood as the causal origins of sensations, are unknowable in themselves; 2) There (...) is no empirical evidence for the kind of causality from which sensations originate; 3) A transcendental causality is nothing but the urge of the intellect to know everything. It is necessary to keep in mind that Helmholtz is a committed empiricist : therefore, he believes that all knowledge originates from sensations. He tries avoiding commitments with any kind of pre-established harmony between the two sides of the causal relation. That is to say, sensible perceptions give us information about the peculiarities of the external world, but the relation between sensations and the reality should be explained and should not be taken for granted. In this paper, I study Helmholtz's struggles with providing a suitable explanation of that relation; in doing so, I also make use of Emile Du Bois-Reymond's work concerning the limits of human understanding, and in particular the transcendent difficulty of grasping the origins of sensations.

This biography of Emil du Bois-Reymond, the most important forgotten intellectual of the nineteenth century, received an Honorable Mention for History of Science, Medicine, and Technology at the 2013 PROSE Awards, was shortlisted for the 2014 John Pickstone Prize (Britain's most prestigious award for the best scholarly book in the history of science), and was named by the American Association for the Advancement of Science as one of the Best Books of 2014. -/- In his own time (1818–1896) (...) du Bois-Reymond grew famous for his groundbreaking research in neuroscience and his provocative addresses on politics and culture. His discovery of the electrical transmission of nerve signals, his innovations in laboratory instrumentation, and his reductionist methodology all helped lay the foundations of modern neuroscience. -/- In addition to describing the pioneering experiments that earned du Bois-Reymond a seat in the Prussian Academy of Sciences and a professorship at the University of Berlin, this book also recounts du Bois-Reymond’s family origins, private life, public service, and lasting influence. In talks that touched on science, philosophy, history, and literature, du Bois-Reymond introduced Darwin to German students (triggering two days of debate in the Prussian parliament), asked on the eve of the Franco-Prussian War whether France had forfeited its right to exist, and proclaimed the mystery of consciousness, heralding the age of doubt. The first modern biography in any language, "Emil du Bois-Reymond" recovers an important chapter in the history of science, the history of ideas, and the history of Germany. (shrink)

In 1872, Emil du Bois-Reymond delivered an astonishing lecture entitled “The Limits of Science” at a Congress of German Scientists and Physicians in Leipzig. No stranger to polemic and bellicose oratory, and possessing among his generation of physiologists unmatched rhetorical abilities, du Bois-Reymond had already attracted much public recognition and acclaim for his denigration of French culture at a time when belligerence and competition between Prussia and France had peaked. Yet, the topic of his 1872 lecture (...) had a signal significance which not only would inform du Bois-Reymond’s subsequent public lectures on literature, art, civilization and science, and the place of Darwin in the modern world, but would also elaborate a mechanistic and fatalistic view of consciousness, one that denied scientific understanding of the phenomenon as even obtainable. Controversy exploded—and from all quarters. Renowned scientists accused him of pessimism and of failing to apprehend the progress of in .. (shrink)

This article examines the science of electrophysiology developed by Emil du Bois-Reymond in Berlin in the 1840s. In it I recount his major findings, the most significant being his proof of the electrical nature of nerve signals. Du Bois-Reymond also went on to detect this same ‘negative variation’, or action current, in live human subjects. In 1850 he travelled to Paris to defend this startling claim. The essay concludes with a discussion of why his demonstration failed (...) to convince his hosts at the French Academy of Sciences. (shrink)

The German pioneer of electrophysiology, Emil du Bois-Reymond (1818–1896), is generally assumed to have remained silent on the subject of the brain. However, the archive of his papers in Berlin contains manuscript notes to a lecture on “The Seat of the Soul” that he delivered to popular audiences in 1884 and 1885. These notes demonstrate that cerebral localization and brain function in general had been concerns of his for quite some time, and that he did not shy away (...) from these subjects. (shrink)

This essay recounts a controversy between a pioneer electrophysiologist, Emil du Bois-Reymond (1818–1896), and his student, Ludimar Hermann (1838–1914). Du Bois-Reymond proposed a molecular explanation for the slight electrical currents that he detected in frog muscles and nerves. Hermann argued that du Bois-Reymond's ‘resting currents’ were an artifact of injury to living tissue. He contested du Bois-Reymond's molecular model, explaining his teacher's observations as electricity produced by chemical decomposition. History has painted Hermann (...) as the wronged party in this dispute. I seek to set the record straight. (shrink)

The late 19th-century Ignorabimus controversy over the limits of scientific knowledge has often been characterized as proclaiming the end of intellectual progress, and by implication, as plunging Germany into a crisis of pessimism from which Liberalism never recovered. My research supports the opposite interpretation. The initiator of the Ignorabimus controversy, Emil du Bois-Reymond, was a physiologist who worked his whole life against the forces of obscurantism, whether they came from the Catholic and Conservative Right or the scientistic and (...) millenarian Left. Du Bois-Reymond’s doubt that scientists would ever elucidate consciousness must therefore be seen as an endorsement, and not a rejection, of his faith in reason. (shrink)

Ernst Haeckel and Emil du Bois-Reymond were the most prominent champions of Darwin in Germany. This essay compares their contributions to popularizing the theory of evolution, drawing special attention to the neglected figure of du Bois-Reymond as a spokesman for a world devoid of natural purpose. It suggests that the historiography of the German reception of Darwin’s theory needs to be reassessed in the light of du Bois-Reymond’s Lucretian outlook.

Vincent du Bois est sculpteur sur pierre. Il a appris à tailler le marbre au pied des carrières de Carrare. Mais sa passion pour Michel-Ange ne l'empêche pas de se définir comme un artiste contemporain. De nos jours, le corps à corps avec la matière n'est plus une étape indispensable pour que l'oeuvre prenne forme. Le sculpteur peut programmer une machine pour se charger de ce travail. En tant qu'artiste, mais aussi en tant que penseur et citoyen, Vincent du (...) Bois interroge cette virtualisation de notre société qui contourne le rapport direct avec la matière et le sens du touché en donnant les pleins pouvoirs à la vue.0Il nous montre comment la révolution numérique, phénomène unique par son ampleur dans l'histoire humaine, signe le triomphe de l'abstraction sur la sensation. Vincent du Bois écrit en sculpteur. Il creuse l'essence des choses comme on taille un bloc, procédant par épanelages successifs jusqu'à ce que se révèle la forme sous-jacente. Elle prend ici les traits d'une question : quel pourra être le rôle du corps dans une société vouée aux écrans? (shrink)

ArgumentIn this paper I present an interpretation of du Bois-Reymond’s thesis on the impossibility of a scientific explanation of consciousness and of its present importance. I reconsider du Bois-Reymond’s speech “On the limits of natural science” in the context of nineteenth-century German philosophy and neurophysiology, pointing out connections and analogies with contemporary arguments on the “hard problem of consciousness.” Du Bois-Reymond’s position turns out to be grounded on an epistemological argument and characterized by a (...) metaphysical skepticism, motivated by the unfruitful speculative tendency of contemporary German philosophy and natural science. In the final sections, I show how contemporary research can benefit from a reconsideration of this position and its context of emergence, which is a good vantage point to trace open problems in consciousness studies back to their historical development.

Abstract.In the wake of the Franco-Prussian war, scientific nationalism became a subject of scientific controversy in Germany. This paper explores the controversy between the cosmopolitan physiologists Hermann von Helmholtz and Emil du Bois-Reymond on the one hand, and the nationalistic economist-philosopher Eugen Dühring and the astrophysicist Johann Carl Friedrich Zöllner on the other. It argues that Helmholtz’ frequent visits to Britain helped him keep abreast of scientific developments there and shaped his ideas of science and society. They also (...) changed his conception of the conservation of energy. German nationalists objected to his British contacts with offensive accusations. They alleged that he had plagiarized his fellow-German Julius Robert Mayer and tried to imitate British physicists. Thus Dühring and Zöllner defended and constructed enduring national stereotypes of German and British science. Whereas Helmholtz put scientific cosmopolitanism into practice, Du Bois-Reymond defended it as an ideology. In contrast to the received view of Du Bois-Reymond as a fervent nationalist, it is argued that he was actually an untimely scientific cosmopolitan. He placed himself in the tradition of Goethe and Schiller's Weimar cosmopolitanism. (shrink)

The exploration of penal censure in this book is inspired by the fortieth anniversary in 2016 of the publication of Andreas von Hirsch's Doing Justice, which opened up a fresh set of issues in theorisation about punishment that eventually led von Hirsch to ground his proposed model of desert-based sentencing on the notion of penal censure. Von Hirsch's work thus provides an obvious starting-point for an exploration of the importance of censure for the justification of punishment, both within von Hirsch's (...) theory of just deserts and from the perspectives of other theoretical approaches. It also provides an opportunity for engaging with censure more broadly from philosophical, sociological-anthropological and individual-psychological perspectives. The essays in this collection map the conceptual territory of censure from these different perspectives, address issues for desert theory that arise from fuller understandings of censure, and consider afresh the role of censure within the jurisprudence of punishment. They show that analyses of censure from different vantage points can significantly enrich punishment theory, not least by providing a conceptual basis for perceiving common ground between and thus connecting different strands of penal theory.

This book considers the way that Cesare Beccaria's slim 1764 volume On Crimes and Punishments influenced policy developments worldwide and over decades, if not centuries, after its publication. For those who turn to Beccaria's work today, the encounter is shaped by that knowledge. Appreciative of his book's dual nature as historical document and repository of ideas, the contributions in this collection address different aspects of the criminal justice theory Beccaria offered his readers and face up to methodological questions raised by (...) meeting a historical text of this kind - unsystematic and by modern standards often under-argued - with modern scholarly conventions in mind. Contributions in the first part of the book engage with Beccaria's 'political theory of criminal justice' through the lenses of political and penal philosophy. How do we get from Beccaria's blending of social-contractarian foundations and proto-utilitarian policy analysis to the concrete set of criminal justice practices Beccaria presents as justified? This leads across to the second part where contributors approach Beccaria's ideas with present-day reforms and developments in mind. Many of his policy proposals and arguments remain significant from our contemporary perspective, their limitations and omissions proving as instructive for the contemporary scholar as their more prescient elements. The third part offers those looking at Beccaria's work today a glimpse into the practical difficulties facing the firebrand author turned public servant during his long career in the Habsburg-Lombardian administration. It puts his work into the broader context of pathways to criminal justice reform in northern Italy, Habsburgian Lombardy, and the Austro-Hungarian Empire in Beccaria's day. (shrink)

This essay considers a long-standing controversy between two nineteenth century pioneers in electrophysiology: the German scientist Emil du Bois-Reymond (1818-1896), and his Italian rival Carlo Matteucci (1811-1868). Historians have generally described their disagreement in du Bois-Reymond’s terms: the product of a contrast in scientific outlook. While not discounting this interpretation, I want to suggest that the controversy was driven as much by the rivals’ similarity as it was by their difference.

Summary of the major innovations of Emil du Bois-Reymond (1818-1896).

ArgumentNineteenth-century Prussia was deeply entrenched in philhellenism, which affected the ideological framework of its public institutions. At Berlin’s Friedrich Wilhelm University, philhellenism provided the rationale for a persistent elevation of the humanities over the burgeoning experimental life sciences. Despite this outspoken hierarchy, professor of physiology Emil du Bois-Reymond eventually managed to increase the prestige of his discipline considerably. We argue that du Bois-Reymond’s use of philhellenic repertoires in his expositions on physiology for the educated German public (...) contributed to the rise of physiology as a renowned scientific discipline. Du Bois-Reymond’s rhetorical strategies helped to disassociate experimental physiology from clinical medicine, legitimize experimental practices, and associate the emerging discipline with the more esteemed humanities and theoretical sciences. His appropriation of philhellenic rhetoric thus spurred the late nineteenth-century change in disciplinary hierarchies and helped to pave the way for the current hegemonic position of the life sciences.

Housed in one volume for the first time are several of the seminal essays on Du Bois's contributions to sociology and critical social theory: from DuBois as inventor of the sociology of race to Du Bois as the first sociologist of American religion; from Du Bois as a pioneer of urban and rural sociology to Du Bois as innovator of the sociology of gender and culture; and finally from Du Bois as groundbreaking sociologist of education (...) and cultural criminologist to Du Bois as critic of the disciplinary decadence of the discipline of sociology. Unlike any other anthology or critical reader on Du Bois, this new volume offers an excellent overview of the critical commentary on arguably one of the most imaginative and innovative, perceptive and prolific founders of the discipline of sociology.

If conduct must be wrongful in order to be justifiably criminalised, how should its wrongfulness be established? I examine a conception of wrongfulness put forward by A. P. Simester, which makes wrongfulness turn on whether the reasons favouring the performance of an action are, all things considered, defeated by the reasons against its performance. I argue that such a view can only generate appropriate substantive constraints in the context of criminalisation if it can distinguish between the sorts of reasons that (...) a verdict of wrongfulness, as a concept distinct from stupidity or selfishness, should attend to, and the sorts of reasons it should leave out. Assuming that this conception of wrongfulness should operate as a constraint on criminalisation in a liberal-democratic state, the only reasons it should include are other-regarding reasons. What matters is whether the agent commits an other-regarding wrong. This conception of wrongfulness helps us further to resolve fundamental questions concerning mala prohibita and the legitimate reach of any duty to obey the law. (shrink)

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

This article examines the notion of the `scientist as a moral person' in the light of the early stages of the commodification of science and the transformation of research into a big enterprise, operating on the principle of the division of labour. These processes were set in train at the end of the 19th century. The article focuses on the concomitant changes in the public persona and the habitus of scientific entrepreneurs. I begin by showing the significance of the professional (...) networks that were built up and maintained to further a group's research ideas and the careers of its members, thus demonstrating one condition on which depended their practice of science and their ability to earn a living. This leads to a characterization of the changing styles of work, thought and life, and to a consideration of public perceptions and of the ways in which a new self-image of scholarship and science was fashioned. A critical discussion of the public role of these mandarin scientists follows in order to highlight the strains created by the commodification of science at a time of international tensions and conflicts, when shared beliefs in scholarly cosmopolitanism were subverted by appeals to science and scholarship to work in the service of one's own nation as its `courtiers'. Various considerations of peculiar analogies between national styles of research and the style of social organization are then noted. In the final section, the article queries the long-term impact of these developments on the ideal of the scientist as a `moral person'. Taking a cue from Max Weber and pursuing reflections by Zygmunt Bauman on `science moralized', I argue that the emergence of a type of `specialists without spirit' was an unintended but fatal consequence of the changes in research practices promoted by scientific entrepreneurs such as Du Bois-Reymond. I conclude that the temptation to sever the ties to a general ethos of civil virtues lay in the rationalization, specialization and potential de-humanization of the objectifying scientific outlook once advocated for its efficiency.

Triumphalist histories of science are nothing new but were, in fact, a staple of the 19th century. This article considers one of the more famous works in the genre and argues that it was motivated by doubt more than by faith.

What responsibilities, if any, do we have towards our genetic offspring, before or after birth and perhaps even before creation, merely by virtue of the genetic link? What claims, if any, arise from the mere genetic parental relation? Should society through its legal arrangements allow 'fatherless' or 'motherless' children to be born, as the current law on medically assisted reproduction involving gamete donation in some legal systems does? Does the possibility of establishing genetic parentage with practical certainty necessitate reform of (...) current legal regimes of parenthood? And what limits, if any, should we set on parental procreative choices in the interests of future children, particularly with regard to genetic engineering and related techniques? These are the questions explored in this book by some of the foremost legal, bioethical and biomedical thinkers. Assembled with a view to assisting the reader to reflect critically on the ongoing social experiment which medically assisted reproduction is today, the essays in this collection highlight what are - and what else might in the nearby future become - possible reproductive options and respond to the difficulties we encounter in assessing these practices and possibilities from our traditional ethical vantage points.
