This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

This paper focuses on Renaissance and early modern readings of Aristotle’s _Meteorologica_ I 7.344a5-8, showing how the various interpretations of this passage were foundational for the establishment of an epistemology based on hypotheses and conjectures, and how this passage informed major philosophical and scientific elaborations of the time, extending its influence beyond the original field of application. The paper considers authors such as Alexander of Aphrodisias, Philoponus, Nifo, Pomponazzi, Wurstisen, Descartes, Galileo, Charleton and Boyle.

Starting from the examination of a passage of the Dialogo sopra i massimi sistemi del mondo that has been largely ignored by the scholarship, in this paper I want to reveal the true nature of Galileo’s epistemology in terms of its epistemic ideal, that is that theory is capable of providing true and certain knowledge about natural phenomena coming from sensation. The investigation examines all the occurrences of the expression sensate esperienze in its singular and plural forms, both in the Latin and in the vernacular. The research proceeds diachronically through an analysis of Galileo’s writings taken in order to show the progressive development of his epistemology. The paper will demonstrate how in thinking about sensate experiences Galileo had in mind as epistemic paradigm that of the epistemology of anatomy.

The concept of »transcendental« is undoubtedly one of the most important terms in Kantian philosophy. For over one hundred and fifty years major Kantian scholars have debated its origin and set out various interpretations. The Kant-Forschung has recently established four different possible sources: 1) Schulmetaphysik 2) Ch. Wolff; 3) A. G. Baumgarten; 4) J. H. Lambert. The aim of this essay is to suggest a different origin and genesis of the Kantian concept of »transcendental« by the methodologies of Quellengeschichte and Begriffsgeschichte, investigating the philosophical and historical background of Königsberg from the beginning of the seventeenth century to Kant and to show reasons for the shift of the concept of »transcendental« from metaphysics to logic. The doctrine of transcendentals was very much alive in Königsberg and already in Scholastic philosophers the »transcendentals« shifted its interest from being to the knowable, from ontology to logic. However, up to 1763, Kant accepts the Wolffian doctrine of transcendentals and the concept of »transcendental« is synonymous to »metaphysical«. In the second half of the Sixties, probably in the wake of the preparatory works to the Beweisgrund, Kant goes deeply into the interpretation of Baumgarten and the »transcendental« becomes synonymous with »essential« in opposition to »metaphysical«. In the wake of Crusius' reflections, instead, »transcendental« becomes »logical« in contrast with »metaphysical«. Beginning in the Seventies, in the preparatory fragments to the Kritik der reinen Vernunft, the »transcendental« establishes itself as a synonymous of »logical« and »essential« in opposition to »metaphysical« and »real«, and it concerns the object of knowledge in general without any reference to the experience. From this conception derives the concept of »transcendental« of the Kritik der reinen Vernunft as an examination of the condition of the possibility of an a priori knowledge. In the conclusion I argue that Kant did not deduce the doctrine of transcendentals from his logic, but that both doctrines are developed simultaneously and that Kant always tried to integrate them with each other. Fragments of the second half of the Seventies show a progressive attempt of this integration, which was doomed to fail.
