Abstract
This study addresses the conceptual affinities between F. W. J. Schelling and Félix RavaissonRavaisson-Mollien, Félix by focusing on the genesis of the link between nature and thought in their respective philosophies. To achieve this, it considers the role of diagrammatic representation in depicting this link—particularly in the figure of the spiral. I argue that, for Schelling, the spiral is a real pattern that suggests the polarity of the mental and the physical whereas, for RavaissonRavaisson-Mollien, Félix, it is a memory of the condition of action and a condition of grace. I cash out this argument by considering not only Schelling’s philosophy of nature, where the spiral is manifest in the vortex of the First Outline of the System of the Philosophy of Nature, and RavaissonRavaisson-Mollien, Félix’s OfHabitHabit, but also RavaissonRavaisson-Mollien, Félix’s essays on fine art, Leonardo da Vinci and the serpentine line.
