Science and Sense

At the end of the nineteenth century, Ludwig Edinger completed the first comparative survey of the microscopic anatomy of vertebrate brains. He is regarded as the founder of the field of comparative neuroanatomy. Modern commentators have misunderstood him to have espoused an anti-Darwinian linear view of brain evolution, harkening to the metaphysics of the scala naturae. This understanding arises, in part, from an increasingly contested view of nineteenth-century morphology in Germany. Edinger did espouse a progressionist, though not strictly linear, view of forebrain evolution, but his work also provided carefully documented evidence that brain stem structures vary in complexity independently from one another and across species in a manner that is not compatible with linear progress. This led Edinger to reject progressionism for all brain structures other than the forebrain roof, based on reasoning not too dissimilar from those his successors used to dismiss it for the forebrain roof.     

A History of the Concept of the Stimulus and the Role it Played in the Neurosciences

The term stimulus, as it was used in science from its earliest appearance in the sixteenth century up to the beginning of the nineteenth century, shows a gradual progress in denotation from the physical object designed to produce nervous and muscular excitation to the generically conceived event or object that initiates sensory or motor activity. To this shift corresponds a shift in the understanding of sensory experience. Johannes Müller's law of specific energy of sensory nerves played a major role in the shift, and Hermann von Helmholtz gave the shift its most thorough philosophical explanation.     

Corpus cartographique pour l'histoire de Damas,Syrie, à la fin de la période ottomane (1760–1924)

Abstract

De manière générale, la cartographie des villes de l'empire ottoman est peu abondante. Au dix‐neuvième siècle, malgré plusieurs réformes administratives, l'autorité publique ne recourait pas à des documents cartographiques pour organiser les travaux d'édilité tandis que les étrangers rencontraient les plus grandes difficultés pour établir des représentations de ces villes. Damas constitue une exception à ce tableau. On dispose de plusieurs cartes antérieures à l'établissement du mandat français (1920) qui sont de qualité inégale. Les auteurs étrangers sont les plus nombreux et les plus fiables; le plus souvent archéologues ou historiens, ils ont dressé des documents partiels par toujours faciles à évaluer. Cependant, et malgré la faiblesse de son volume (sept documents), le corpus des premières cartes de Damas constitue une source essentielle pour l'histoire du développement spatial de la ville entre le milieu du dix‐neuvième siècle et l'établissement du pouvoir mandataire.     

Confabulations: A Conceptual History

Confabulations are inaccurate or false narratives purporting to convey information about world or self. It is the received view that they are uttered by subjects intent on ‘covering up’ for a putative memory deficit. The epidemiology of confabulations is unknown. Speculated causes include amnesia, embarrassment, ‘frontal lobe’ damage, a subtype of ‘personality’, a dream-like event, and a disturbance of the self. Historical analysis shows that ‘confabulation’ was constructed at the turn of the century as part of a network of concepts (e.g. delusion, fixed idea, etc.) Meant to capture narratives with dubious content. This paper deals with the history of the construction of the word and concept of confabulation and with earlier recognitions of the behaviours that serve as their referent and puts forward a model based on historical data. Two phenomena are included under ‘confabulation’: ‘untrue’ utterances by subjects with memory impairment and ‘fantastic’ utterances marshalled with conviction by subjects suffering from psychoses and no memory deficit. Under different disguises, the ‘covering up’ or ‘gap filling’ hypothesis is still going strong. Although superficially plausible, it poses problems in regards to the issue of ‘awareness of purpose’: if full awareness is presumed, then it is difficult to differentiate confabulations from lying; if no awareness is presumed then the semantics of the concept of ‘purpose’ is severely stretched and confabulations cannot be differentiated from delusions. The received view of confabulations also neglects the clinical observation that confabulations (particularly provoked ones!) Do occur in dialogical situations: i.e., the manner of the asking may increase their probability. It is suggested here that confabulations are a disorder of a putative narrative function which is also found in ‘normal’ subjects. It is also hypothesized that this trait is normally distributed in the population. In the absence of adequate epidemiological information, research efforts should be directed at mapping the distribution of this narrative (or confabulatory) capacity in the community at large. Only then it will be possible to understand the significance of its disorders. In the long term, this approach will prove more heuristic than unwarranted speculation based on few anecdotal cases.     

Raumvorstellungen und Erkenntnismodelle im 18. Jahrhundert

Since the late 17^th century, two physical concepts of space exist. Isaac Newton's theory of an immovable ‘absolute space’ made it possible to explain motion and force by the quality of material elements. Less influential was Gottfried Wilhelm Leibniz's concept of space as an ‘order of coexistence’, which focuses, contrary to Newton, on the relationship between material bodies. The author argues that both concepts not only concern physical notions, but also include general models to explain cause, effect and relation. In an analogy to Newton's ‘absolute space’, theories of natural law employ the state of nature to explain society according to the anthropological quality of human beings. Leibniz's concept, in contrast, is used to elaborate theories of complex dynamic interactions and relationships. This essay attempts to illustrate the application of Leibniz's concept with examples of 18^th century natural history, demography, economic theory and Charles Bonnet's natural law.     

普鲁士改革时期的浪漫主义:思想与行动

浪漫主义运动发生于18世纪末至19世纪30年代,是一场构建民族精神特质的思想塑造运动。柏林的宗教氛围、普鲁士君主制传统,特别是作为其“血脉”的等级制度在法国革命冲击后依然完好无损地保留,使浪漫主义者得以将普鲁士作为政治实验场开展活动。亚当·米勒和斯泰因是两位改革时期的浪漫派代表,一个从观念出发,将君主制、等级制“浪漫化”,用于指导改革;而另一个则从历史经验出发,在实践中尝试将君主制和等级制做出顺应时代的改变。他们的思想和实践对普鲁士的改革进程产生了重要影响。     

The Influence of Goethe's Farbenlehre on Early Geological Map Colouring: Goethe's Contribution to Christian Keferstein's General Charte von Teutschland (1821)

An analysis of Goethe's Farbenlehre (Theory of Colours), and of its significance for the development of geological mapping, requires an interdisciplinary approach and specific knowledge of both the history of cartography and the science of chromatics. Thus far there has been little research in either of these areas by historians of geological cartography or by students of Goethe's Farbenlehre. In particular, the influence of Goethe's Theory of Colours on early geological map colouring has not yet been explored, and the present article is an attempt to rectify that omission. After an introduction to the emergence of geological maps during the Age of Enlightenment, the discussion focuses on Goethe's substantial contribution to the selection of colours for Christian Keferstein's General Charte von Teutschland (1821). Detailed study of the available textual and cartographical source material reveals that Goethe applied the principles of his Farbenlehre as a basis for the colour chart that Keferstein used to delineate the rock formations shown on his map. The article concludes with a brief consideration of the extent to which the joint Goethe–Keferstein venture influenced the future of geological map design.     

Rehabilitating political parties: an examination of the writings of Hans Kelsen

This paper focuses on Hans Kelsen’s reflections on political parties. During the interwar period, Kelsen participated in a controversy over whether political parties were a necessary part of the democratic process. The debate forced Kelsen to produce a defence of political parties to emphasise their functionality and define their place in his particular definition of democracy. This contribution considers the following aspects. First, the reasons why Kelsen thought political parties are necessary for democratic life are explained. Second, the doctrinal oppositions against which he elaborated his defence of political parties are clarified. Third, the programme that Kelsen conceived of to enhance political parties in a constitutional democracy is examined. Finally, the contemporary questions that have arisen in relation to Kelsen’s conception of political parties are scrutinised. Kelsen’s contribution to the debate about the role of political parties was intimately related to the presence of strong criticisms of that role. This makes his reflections even more interesting today, considering the present relative decline of the political role and appeal of parties.
