Historians of Science, Creators. Philosophical Perspectives on the History of Science on the light of Il Saggiatore by Galileo Galilei

This essay reads Galileo Galilei’s Il Saggiatore as an exemplary meeting point between the history of science, the history of philosophy, and the philosophy of science. Through his confrontation with Orazio Grassi and the Jesuit tradition that defended Tycho Brahe’s astronomical system, Galileo transforms the controversy over comets into an epistemological laboratory where experience, language, and narrative intertwine. The essay highlights three creative dimensions characteristic of the historian of science’s work: the creation of worldviews through narrative; a reflection about the material creation associated with scientific instruments and objects; and the logical-epistemic creation, which investigates styles of reasoning and forms of argumentation and dialogue. The proposed interdisciplinary approach weaves together historiography, philosophy, and the analysis of scientific texts, suggesting that the history of science is not merely a description of the past but above all a critical exercise in interpretation. In doing so, it provides conceptual tools for developing philosophical categories useful for understanding science. Il Saggiatore thus emerges as a paradigm for grasping the tension between experience and theory, between authority and creativity, and for recognizing the role of narrative in the construction of scientific rationality.
