In this paper we examine the study of minerals from the Renaissance to the early nineteenth century in the light of the work of Michel Foucault on the history of systems of thought. In spite of a certain number of theoretical problems, Foucault's enterprise opens up to the historian of science a vast terrain for exploration. But this is the place neither for a general exegesis nor for a general criticism of his position; our aim here is the more modest (...) one of taking certain points from Foucault's study,The order of things, and seeing how far they can be extended into an area not explicitly considered in that work.

A number of authors have drawn attention to the contributions to geology of Robert Hooke, and it has been pointed out that in several ways his ideas were more advanced than those of Steno, who is sometimes taken to be the founder of geology as a scientific discipline. Moreover, it has been argued that in a number of instances Hooke should receive the credit for ideas which are usually believed to have originated in the work of James Hutton. This recognition (...) of the significance of Hooke's work is regarded by the present writer as being well founded. But, by contrast, the relationship between Hooke's geological ideas and his views on the proper methods for conducting scientific enquiries has been largely overlooked, and his views on the methodology of science, as revealed in his Posthumous works, have received little discussion. Moreover, on one of the few occasions on which they were discussed, by William Whewell, they were belittled. Whewell regarded Hooke's methodological contribution as merely ‘an attempt to adapt the Novum organon to the age which succeeded its publication’, 5 and he implied that the ‘same imperfections’ were to be found in the writings of both Hooke and Bacon. The influence of Bacon is, to be sure, most obvious in Hooke's general philosophy. Nevertheless, it will be argued that Hooke had a much clearer idea than did Bacon of the importance of so-called ‘hypothetico-deductive’ methods in science, and that in many ways his methodological views represent a significant advance on those of Bacon.

SummaryEarly geological investigations in the St David's area (Pembrokeshire) are described, particularly the work of Murchison. In a reconnaissance survey in 1835, he regarded a ridge of rocks at St David's as intrusive in unfossiliferous Cambrian; and the early Survey mapping (chiefly the work of Aveline and Ramsay) was conducted on that assumption, leading to the publication of maps in 1845 and 1857. The latter represented the margins of the St David's ridge as ‘Altered Cambrian’. So the supposedly intrusive ‘syenite’ (...) was regarded as younger, and there was no Precambrian. These views were challenged by a local doctor, Henry Hicks, who developed an idea of the ex-Survey palaeontologist John Salter that the rocks of the ridge were stratified and had formed a Precambrian island, round which Cambrian sediments (now confirmed by fossil discoveries) had been deposited. Hicks subsequently proposed subdivision of his Precambrian into ‘Dimetian’, ‘Pebidian’, and (later) ‘Arvonian’, and he attempted correlations with rocks in Shropshire, North Wales, and even North America, seeking to develop the neo-Neptunist ideas of Sterry Hunt. The challenge to the Survey's work was countered in the 1880s by the Director General, Geikie, who showed that Hicks's idea of stratification in the Dimetian was mistaken. A heated controversy developed, several amateur geologists, supported by a group of Cambridge Sedgwickians, forming a coalition of ‘Archaeans’ against the Survey. Geikie was supported by Lloyd Morgan. Attention focused particularly on Ogof Lle-sugn Cave and St Non's Arch, with theory/controversy-ladenness of observations evident on both sides. Evidence from an eyewitness student record of a Geological Society meeting reveals the ‘sanit`ized’ nature of the official summary of the debate in QJGS. Field mapping early in the twentieth century by J. F. N. Green allowed a compromise consensus to be achieved, but Green's evidence for unconformity between the Cambrian and the Dimetian, obtained by excavation, can no longer be verified, and his consensual history of the area may need revision. Unconformity between the Cambrian and the Pebidian tuffs is not in doubt, however, and Precambrian at St David's is accepted. The study exhibits features of geological controversy and the British geological community in the nineteenth century. It also furnishes a further instance of the great influence of Murchison in nineteenth-century British geology and the side-effects of his controversy with Sedgwick. (shrink)

A translation of Kant's early paper, ‘Die Frage, ob die Erde veralte, physikalisch erwogen’ is presented, and the main features of his position on this question in 1754 are summarized. In that year, Kant believed that the Earth was ageing, and that it was about 6000 years old. The paper allows us to understand the approximate outline of Kant's general ‘theory of the Earth’, and the relation of this theory to the cosmogony that he propounded in 1755. His ideas on (...) the processes of erosion, and the formation of rivers, deltas and sandbanks, are noteworthy, and provide a contribution to the eighteenth-century literature on the denudation dilemma. Kant's general theory of erosion and deposition was, it seems, based to a significant extent on his knowledge of the geographical features of the Königsberg district. The general teleological position underpinning his philosophy may be discerned in this early paper, and he may be thought of as having been trying to orientate himself in space and time, so to speak, before undertaking his major reconstructions in philosophy.

The characteristics of inductivist historiography of science, as practised by earlier scientist/historians, and Whig historiography, as practised by earlier political historians, are described, according to the accounts of Agassi and Butterfield. It is suggested that the writings of Geikie on the history of geology allow us to characterize him as a Whig/inductivist historian of science who formulated anachronistic judgements. It is further suggested that his writings have had a considerable long-term effect on interpretations of the history of geology. The character (...) of Geikie's historiography is related to his social, political and religious views, his historicism, and his romantic enthusiasm for Nature. His methodological pronouncements are examined: he believed that the present is the key to the past, and also that the past is the key to the present. He was an empiricist and inductivist. These epistemological and methodological views impinged on his historiography of science. If one attempts to criticize Geikie's historiography, though one may try to judge his work according to the norms of his own day and age, historical anachronism cannot be avoided entirely and one may oneself be charged with acting ‘Whiggishly’. Historians of science, in the process of professionalization, have accepted the historiographical norms of general historians , but in so doing have inherited a problem that arises whenever they contemplate earlier historical writings. It is suggested that there may be more room for Whiggish historiography of science than is presently deemed acceptable. Alternatively, one may wish to draw a careful distinction between science and its meta-discipline, the historiography of science. Whig historiography conflates the two, and the work of Geikie provides a good illustration of this. (shrink)

Notice is given of the discovery of two reports and an accompanying manuscript map by Andrew Ramsay, on the geology of the St David's area, Pembrokeshire. This adds to previously published information on early geological work in this important region: Ramsay's report throw some light on his attitude towards Murchison's ideas on Welsh stratigraphy. The map is the earliest known version of the Survey's St David's sheet.

Bailey Willis was the second major American geologist to undertake reconnaissance research in China--in the years 1903-04. Together with the stratigrapher Eliot Blackwelder, topographer Harvey Sargent, and guide Li Shan, he travelled first in Shandong Province, then from Peking to Xian, thence across the mountains into Sichuan, and then by river via the Yangzi Gorges to Shanghai. It was hoped that they would discover the primeval ancestor of trilobites in China, but the search proved unsuccessful. Willis's stratigraphic findings are described, (...) as are his structural interpretations of what he observed in China. His work in China gave rise to some unfounded speculations about the possible causes of lateral Earth movements, due to rocks of different densities being adjacent to one another in the Earth's crust. These ideas were followed by several other 'theories of the Earth' during Willis's later career, some of which were also probably related to his experiences in China. He seemingly practised the formulation of 'multiple working hypotheses'. The paper also discusses the influence of Willis's survey and stratigraphic work on the subsequent development of Chinese geology, with particular attention given to the various meanings of the term 'Sinian System'. Mention is made of later work in China on Lower Cambrian stratigraphy. (shrink)

An account is given of the work on glacial phenomena in the English Lake District from the time of Adam Sedgwick until the mid-twentieth century, with emphasis on the nineteenth century. In the early years, the following theories were envisaged: 'diluvialism'; the theory of 'waves of translation'; the theory of 'ice rafting'; the 'glacial-submergence' hypothesis ; and the 'land-ice' theory. While it was quite easy to recognize ice action and the former existence of glaciers, it was difficult to work out (...) a persuasive sequence of events that would account satisfactorily for the great variety and quantity of evidence available, considering land-forms, and the distribution of moraines, tills, gravels, and glacial erratics. When the first systematic geological survey was being undertaken in the Lake District both local amateurs and the surveyors favoured the glacial-submergence theory, but there were problems about explaining the distribution of glacial erratics, and controversy developed as to whether this distribution was best explained in terms of floating icebergs or landice. The problem was difficult in that there was uncertainty as to how many glaciations there had been, though the preferred number was two, following the early observations in Wales by Andrew Ramsay, in Lancashire by Edward Hull and others, and by some Continental geologists, of two different tills, and one intermediate water-deposited unit. These seemed to have equivalents in the Lake District. However, the Scottish surveyors, under the influence of their theorist colleague, James Croll, with his astronomical explanation of ice ages, favoured multiple glaciations. Croll himself sought to apply the land-ice theory to explain the distribution of glacial erratics in the regions round the Lake District. James Geikie read widely in the Continental literature, and thought that the theory of several glaciations, developed by Albrecht Penck in the 1880s, on the basis of observations of the valleys and rivers terraces running north from the Alps, fitted well with Croll's theory. Thus the idea of a sequence of glaciations was applied to Britain with some success, partly as a result of Geikie's advocacy. But the evidence of such a sequence in the Lake District itself was by no means clear, and it was not developed for the region until the work of Frederick Trotter and Sidney Hollingworth . In the meantime, much geomorphological work on the form and formation of lakes and tarns had been done by the chief aficionado of Lakeland geology, Cambridge professor, John Marr. But he thought there might have been only one major glaciation. The paradox is that, for England, the glacial sequence has had to be worked out more by examination of deposits in the flatter southern regions, as much as in the mountains where the glaciers were formed and most active. In the Lakeland mountains, as in other parts of the world, the last glaciation has tended to remove or obscure the products of earlier glaciations. (shrink)

SummaryAn account is given of one of the most heated controversies in nineteenth-century British geology—the battle between Archibald Geikie and John Judd concerning the interpretation of the Palaeogene igneous rocks of the Inner Hebrides, particularly those of the Cuillins and the Red Hills of Skye. The controversy erupted in the first instance over the question of the respective ‘territories’ of the two geologists, then developed into disagreement as to the origin of the plateau lavas of Skye: were they formed from (...) fissure eruptions (Geikie's view) or from the outpourings of great volcanoes (Judd's view)? Debate then focused on the question of the relative age of the gabbro of the Cuillins and the granite (granophyre) of the Red Hills. A certain locality at Druim Hain (Druim an Eihdne) at the junction between the two rock-types became crucial for the dispute. Following earlier observers, Judd held that the granite was older and had been intruded by the gabbro. Geikie took the opposite view. Geikie's work relied particularly on field observations, for which he was assisted by several other geologists. Judd, who worked by himself, rested his argument more on the evidence furnished by petrology, using thin sections. Both geologists were influenced by Ferdinand von Richthofen. Geikie's work appeared to be vindicated in his own lifetime by the map work of Alfred Harker, which effectively closed the controversy. But later commentators such as Walker hold that in a sense both were correct. There were indeed great volcanoes active in the Inner Hebrides in the Palaeogene, as well as fissure eruptions. Moreover, recent mapping does not support all the observations of Geikie and Harker. The controversy illustrates different styles in nineteenth-century geology, with petrological arguments, based on the examination of thin sections, pitted against field observations. It may also be seen as being linked with the ongoing rivalry in the nineteenth century between the members of the Geological Survey (particularly the Directors General) and the ‘amateur’ university geologists. Geikie prevailed in the debate in part because he was able to draw on more resources for its prosecution, being helped by various friends and members of the Geological Survey. The study draws on the newly discovered Geikie archive at Haslemere, which contains his complete outgoing official correspondence, and 27 of his field notebooks, previously missing. With the help of this material, it is possible to gain a clearer insight into the methods deployed by Geikie in his fieldwork, and his ways of working and thinking. (shrink)

The paper discusses some of the problems that may be encountered in writing the history of geology with the help of non-written sources, but also offers suggestions as to the kinds of sources that may prove useful. It considers particularly the well-known proposition of R. G. Collingwood that historical writing should involve the attempted 're-enactment of past experience', and also criticisms of such idealist philosophies of history as have been made by Michel Foucault. In considering the relative merits of these (...) two contrasting views, an example is taken from the author's own work, which illustrates the point that attempted 'thought reading', in the manner commended by Collingwood, can sometimes lead to error; thus Foucault's position gains some support. However, it is contended that so much geological knowledge is specific to particular localities that much of the primary literature may be unintelligible without at least some first-hand knowledge of those localities. Thus, an appropriate mix of written and unwritten sources is necessary for writing the history of geology. (shrink)

An account is given of the reconnaissance investigations in China of the American geologist and mining engineer, Raphael Pumpelly. Pumpelly is well known to Chinese historians of science as being the first professionally trained Western geologist to examine the geology of China. This paper offers a reconstruction of Pumpelly's journeys and seeks to understand what an explorer might do in a land where there had been no previous geological investigations by persons trained in the methods of Western science. Pumpelly's hypotheses (...) about the geology of China are also analysed and a sketch of his influence on the history of Chinese geology is given. (shrink)
