The purpose of this article is to expose, comment on and analyse the procedures of scientific research and the experimental techniques in the biomedical sciences of the 17th century, with Francesco Redi as the main figure of this study. Specifically, we would like to show how the path through which experimentation takes place in the field of biomedical sciences is not necessarily animated by the physical-mathematical spirit that would supposedly characterise the trite category of «Scientific Revolution», without it being prejudice (...) for the use of precise scientific methods and the obtaining of highly effective experimental results.

This paper reconstructs the natural philosophical method of Geminiano Montanari, one of the most prominent Italian natural philosophers of the late seventeenth century. Montanari’s views are used as a case study to assess recent claims concerning early modern experimental philosophy. Having presented the distinctive tenets of seventeenth-century experimental philosophers, I argue that Montanari adheres to them explicitly, thoroughly, and consistently. The study of Montanari’s views supports three claims. First, experimental philosophy was not an exclusively British phenomenon. Second, in spite of (...) some portrayals of experimental philosophy as an ‘atheoretical’ or ‘purely descriptive’ enterprise, experimental philosophers could consistently endorse a variety of natural philosophical explanations and postulate theoretical entities. Third, experimental philosophy and mechanical philosophy were not, as such, antagonistic. They could be consistently combined in a single philosophical enterprise. (shrink)

At the beginning of the eighties of the last century, the issue of “patronage” began to arouse scholarly interest and gained importance. Galileo became a test case: his importance, and the importance of patronage – and that of the Medici in particular – go beyond the historical junction of the scientific revolution and have corollaries in the more general attitude to science and knowledge. This case furnished a new line of research for the historical sociology of science. As far as (...) Galileo is concerned, my claim is that the new trend belongs to post-modern historiography, rather than to post-Renaissance Medici patronage. (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)

Francesco Redi’s seventeenth-century experiments on insect generation are regarded as a key contribution to the downfall of belief in spontaneous generation. Scholars praise Redi for his experiments demonstrating that meat does not generate insects, but condemn him for his claim elsewhere that trees can generate wasps and gallflies. He has been charged with rejecting spontaneous generation only to change his mind and accept it, and in the process, with failing as a rigorous experimental philosopher. In this paper I defend Redi (...) from both of these charges. In doing so, I draw some broader lessons for our understanding of spontaneous generation. ‘Spontaneous generation’ does not refer to a single theory, but rather a landscape of possible views. I analyze Redi’s theoretical commitments and situate them within this landscape, and argue that his error in the case of insects from plants is not as problematic as previous commentators have said it is. In his research on gall insects Redi was addressing a different question from that of his experiments on insect generation—the question was not “Can insects come from nonliving matter?,” but rather, “Can insects come from living organisms which are not their parents?” In the latter case, he gave an answer which we now know to be false, but this was not due to any failure in his rigor as an experimental philosopher.
