The growth of modern science has been accompanied by the growth of professionalization. We can unquestionably speak of professional science since the nineteenth century, although historians dispute about where, when and how much. It is much more problematic and anachronistic to do so of the late seventeenth century, despite the familiar view that the period saw the origin of modern experimental science. This paper explores the broad implications of that problem.

Over the last forty years several historians have drawn attention to aspects of the activities of lecturers on natural philosophy in Britain in the eighteenth century. Hans and others looked at the part these lecturers played in the development of education, particularly adult education. Musson and Robinson considered the possible connection between the work of the lecturers and the growth of industry, and Inkster and others have explored the relationship between lecturers and the institutions set up to support science, especially (...) around 1800.4 More recently, Schaffer has pointed to the parallels between the performances of the lecturers on natural philosophy and other contemporary cultural activities. As a consequence of these studies we know much more about the work of the lecturers, its significance, and, to a lesser extent, their relationship to their audience. (shrink)

The concept of electrical conductivity, or, as initially coined by Stephen Gray , ‘electrical communication’, has always been assigned an important role in the history of electrical research. Some thirty-five years after Gray's ‘electrical communication’ acquired wide attention, Priestley employed the concept of conductivity to define physical reality, thus giving a privileged position to the science he himself endeavoured to cultivate. As he argued in the introduction to The History and Present State of Electricity , ‘the electrical fluid is no (...) local, or occasional agent in the theatre of the world. Late discoveries show that its presence and effects are every where … It is not, like magnetism, confined to one kind of bodies, but every thing we know is a conductor or nonconductor of electricity’. Contemporary historians, for example, Heilbron, Home and Hackmann, link the concept of conductivity to a radical transformation of electrical research which pertained to its mode of organization and the definition of its subject-matter, and which culminated in its emergence as a distinctive branch of eighteenth-century ‘experimental philosophy’.

This volume, The Brazilian Studies in the Philosophy and History of Science, is the first attempt to present to a general audience, works from Brazil on this subject. The included papers are original, covering a remarkable number of relevant topics of philosophy of science, logic and on the history of science. The Brazilian community has increased in the last years in quantity and in quality of the works, most of them being published in respectable international journals on the subject. The (...) chapters of this volume are forwarded by a general introduction, which aims to sketch not only the contents of the chapters, but it is conceived as a historical and conceptual guide to the development of the field in Brazil. The introduction intends to be useful to the reader, and not only to the specialist, helping them to evaluate the increase in production of this country within the international context. (shrink)
