Export and smuggling of Spanish platina in the eighteenth century

The European demand for platina in the late eighteenth and early nineteenth centuries could not be met by the Spanish authorities who only authorized limited exports of the mineral, approximately 267 kg between 1750 and 1804. The lack of an adequate commercial structure generated direct trade between Latin America and Europe, particularly England. This article is an attempt to analyse and to quantify the three European sources of platina: exports from Spain, shipments of platina consigned by European travellers, and direct trade. The reasons for the latter are studied, exemplified by the Wollaston case, and legal and direct trade are compared.     

Presocratic discourse in poetry and prose: The case of Empedocles and Anaxagoras

This paper explores the differences between poetry and prose in philosophical writing by examining two Pre-Socratic fragments, one in verse and one in prose, that express a very similar thought: Empedocles 59 B 17 Diels/Kranz and Anaxagoras 31 B 8 D./K. Although at first it might seem as though there is a simple division between Empedocles’ opaque and allusive hexameters and Anaxagoras’ sober prose, when we look in detail at the language used by the two authors, a close reading of the passages reveals a more complex picture. Both authors place rhetorical emphasis on their own role as innovator; Anaxagoras’ prose shows a careful attention to style and word choice no less than Empedocles’ poetry, and Empedocles’ poetry itself reflects the range of stylistic registers and types of material that hexameter could be used for in antiquity. There is no simple antithesis between prose style and hexametric poetry, and the words and stylistic devices an author chooses are constitutive of the thought he expresses.     

Pathogenic enterococci: new developments in the 21st century

Enterococci, traditionally viewed as Gram-positive commensal bacteria inhabiting the alimentary canals of humans and animals, are now acknowledged to be organisms capable of causing life-threatening infections in humans, especially in the nosocomial environment. The existence of enterococci in such a dual role is facilitated, at least in part, by its intrinsic and acquired resistance to virtually all antibiotics currently in use. Beginning with the initial identification of a streptococci of fecal origin in the late 19th century, enterococci have been studied for over a century now. A number of comprehensive reviews during this time have addressed various aspects of enterococci, including classification, biology, virulence, antibiotic resistance and so on. This review specifically addresses the important advances in the field of enterococcal research that have occurred since the beginning of the 21st century. Most notable among these developments have been the insights into enterococcal genomes and pathogenicity.Received 10 April 2003; received after revision 31 May 2003; accepted 3 June 2003     

William Whewell,natural theology and the philosophy of science in mid nineteenth century Britain

This article aims to reveal the moral and theological dimensions of William Whewell's philosophy of science. It suggests that, in addition to an internalist account of Whewell's method and epistemology, there is a need to view his philosophy of science (and knowledge) within the intellectual context constituted by the assumptions of natural theology. It argues that writers of natural theology saw man's ability to know the world as an indication of his special place in nature, and that epistemological theories were therefore invested with moral and theological significance. Whewell's work is interpreted as an attempt to dissociate natural science from Utilitarianism and empiricist philosophy: he sought to promote a philosophy of science which guaranteed the principles of natural theology and the values of Christianity. But the idealist epistemology which he proposed was criticized by both scientists and theologians. In 1853 (in his book Of the plurality of worlds), again within the framework of natural theology, Whewell attempted to justify this epistemology by affirming the metaphysics of a Christian Platonism. From this position, Whewell defended natural theology against the metaphysical scepticism of both Henry Mansel and the positivists.     

Theories of cohesion in the seventeenth century

This paper attempts a critical examination of the thesis that an apprenticeship to a Lancaster druggist was, for Edward Frankland, a wholly inappropriate preparation for a career in chemistry. This view, which stems directly from Frankland himself, is defective in several ways. It fails to take into account certain benefits which he accepted as valuable; it implies an exceptional degree of ‘negligence’ which was in fact quite typical; it ignores certain positive indicators of the value of such experience; and it involves questionable value-judgments on the behaviour of one individual, the druggist Stephen Ross. Although Frankland's perspective may be no longer acceptable, the reasons for its inadequacy are perhaps the most important aspect of the whole affair. Their identification raises questions of historiography of wider significance, while the whole episode underlines certain issues in scientific training that were to become crucial in the growth of Victorian chemistry in Britain.     

Disciplining cattle reproduction: Veterinary reproductive science,bull infertility,and the mid-twentieth century transformation of Swedish dairy cattle breeding

From the 1940s, reproductive physiology and livestock genetics transformed dairy cattle breeding and became, in conjunction with the new reproductive technology of artificial insemination, important drivers of agricultural modernization in most countries with significant dairying. While this is well known, we know less about the longer-term interplay between specifically veterinary interests in reproduction and the institutional development of cattle breeding. In the present paper, I therefore examine the veterinary disciplining of cattle reproduction—its constitution as a veterinary scientific discipline and the extension of veterinary control over it—in mid-twentieth century Sweden. I show how veterinary scientists derived legitimacy for their fledgling discipline by engaging with the problems of practical breeding, and that in doing so they also exercised influence over breeding’s development. By making bulls’ reproductive disturbances visible and framing them as hereditary, they undermined the conservative interests of commercial breeders. The development of veterinary reproductive science thereby played an important role in reshaping the culture, economy, and regulations of cattle breeding in Sweden as it shifted from a prewar regime dominated by elite breeders to a postwar regime that, ostensibly, served all dairy farmers in the country.     

Paul Natorp and the emergence of anti-psychologism in the nineteenth century

This paper examines the anti-psychologism of Paul Natorp, a Marburg School Neo-Kantian. It identifies both Natorp’s principle argument against psychologism and the views underlying the argument that give it its force. Natorp’s argument depends for its success on his view that certain scientific laws constitute the intersubjective content of knowledge. That view in turn depends on Natorp’s conception of subjectivity, so it is only against the background of his conception of subjectivity that his reasons for rejecting psychologism make sense. This interpretation of Natorp suggests that attention paid to late nineteenth century theories of subjectivity and philosophy of psychology could improve our understanding of the emergence of anti-psychologism in that period.
