An anomaly in the Cartesian science of the passions: the case of intellectual emotions in Descartes’ Treatise of the Passion Authors Natanael F. Pacheco Cornejo Universitat de les Illes Balears Keywords: Descartes, science, intellectual emotions, physiology, physics, metaphysics, passions. Abstract The purpose of this paper is to examine a peculiar kind of emotions, intellectual emotions, in Descartes’ scientific treatise about the human emotions, the Treatise of the passions. In the first place, we will see the scope and limits of its approach «en physicien», and the need to consider a different approach to examine the nature of intellectual emotions, an approach en métaphysicien. Hereafter, we will develop this approach by analysing the structure of the intellectual emotions (its emotive and its epistemic dimension). Finally, we will conclude with some remarks about the complementarity of both approaches, physical and metaphysical, in Descartes’ scientific thought.Keywords: Descartes, science, intellectual emotions, physiology, physics, metaphysics, passions.
