This essay offers some reflections on the recent history of the disputes about the relation between history and philosophy of science (HPS) and the merits and prospects of HPS as an intellectual endeavor. As everyone knows, the issue was hotly debated in the 1960s and 1970s. That was the hey-day of the slogan "history without philosophy of science is blind, philosophy without history of science is empty" as well as of the many variations on the theme of HPS as a (...) "marriage of convenience," "intimate relation," or "marriage for the sake of reason." There was a flurry of interest in the early 1990s, as evidenced by sections in the 1992 and 1994 issues of PSA, entitled: "Do the History of Science and the Philosophy of .. (shrink)

The paper begins with a detailed reconstruction of the development of Ian Hacking’s theory of scientific ‘styles of reasoning’, paying particular attention to Alistair Crombie’s influence, and suggesting that Hacking’s theory deserves to come under the title ‘historical epistemology’. Subsequently, the paper seeks to establish three critical theses. First, Hacking’s reliance on Crombie leads him to adopt an outdated historiographical position; second, Hacking is unsuccessful in his attempt to distance historical epistemology from epistemic relativism; and third, Hacking has not offered (...) convincing criteria for individuating styles of reasoning. Keywords: Styles of reasoning; Historical epistemology; Ian Hacking; Alistair Crombie; Relativism; Sociology of scientific knowledge. (shrink)

The last thirty years of scholarship in western medieval philosophical historiography have seen a number of reflections on the methodological paradigms, schools, trends, and dominant approaches in the field. As a contribution to this ongoing assessment of the existing methods of studies in medieval philosophy and theology and a supplement to classifications offered by M. Colish, J. Inglis, C. König-Pralong, J. Marenbon, A. de Libera, and others, the article offers another explanatory tool. Here is a description of an imaginary system (...) of methodological coordinates that systematizes the current tendencies by placing them in a three-dimensional system of axes. Every axis corresponds to a certain aspect of the historical and systematic research in medieval thought and symbolizes a possible movement between two extremes representing opposite methodological values and directions. The methods and approaches practiced in recent studies in medieval philosophy and theology might be schematically located inside this general system of argumentational, focal (or objectival), and (con)textual axes with their intersection identified with what some scholars call the “integral” model of study. This explanatory tool allows one to see how current approaches and methods form a panoply of axes that belong together in one complex grid and helps to visualize the tapestry of existing approaches in medieval philosophical historiography.

In this chapter I investigate the prospects of integrated history and philosophy of science, by examining how philosophical issues raised by “hidden entities”, entities that are not accessible to unmediated observation, can enrich the historical investigation of their careers. Conversely, I suggest that the history of those entities has important lessons to teach to the philosophy of science. Hidden entities have played a crucial role in the development of the natural sciences. Despite their centrality to past scientific practice, however, several (...) of them (e.g., phlogiston, caloric, and the ether) turned out to be fictitious. For this reason, they have figured prominently in recent debates on scientific realism. The issues I explore in this paper are entangled with those debates. I argue that our understanding of hidden entities and their role in experimental practice can be enhanced by adopting an integrated historical-cum-philosophical approach. On the one hand, philosophical reflection on the reality of those entities has a lot to gain by examining historically how they were ntroduced and investigated. On the other hand, the historical reconstruction of the careers of those entities may profit from philosophical reflection on their existence. (shrink)

This essay is a contribution to the history of methodological thought. I focus on key methodological criteria for successful experimentation, replication and multiple determinations of empirical evidence. Drawing on reports of experiments with viper venom from the late seventeenth and late eighteenth centuries, as well as on present-day methodological thought I examine whether past experimenters regarded repetition, replication, and multiple determinations as criteria for validity; what exactly they meant by this; what they hoped to gain by repeating, varying, triangulating, and (...) replicating; and how relevant these criteria were for them. I also consider if this analysis has implications for current philosophical work on the methodology of experimental practice. (shrink)
