Abstract

Among late Renaissance and early Modern philosophers, the concepts of “sympathy” or “harmony” are a recurring theme. My goal is to show that theories which rely on such concepts, far from being an attempt to avoid the emerging mechanistic or empirical trends, are actually the form which these trends took in the wake of an increasing disenchantment with Aristotelian psychology. Fracastorius, Suarez and Descartes provide the texts: their accounts of the interaction between cognitive faculties exhibit a growing awareness that the conception of causality had to be supplemented. And while each appears to share the general belief that aspects of the Thomistic-Aristotelian framework can survive the necessary changes, they disagree about how much dogmatic psychology has to be discarded. What they decide to leave in and the reasons given for discarding the rest provide insight into the history of explanation. It is in the metaphysics of harmony that we can trace the early growth of Rationalism.
