*Transformations de la métaphysique* is a scholarly study of the changes and tensions within metaphysical thought as they appear in Friedrich Wilhelm Joseph von Schelling’s transcendental philosophy. Emmanuel Cattin examines how Schelling reworks the conditions of philosophical reflection, moving beyond inherited models of metaphysics while preserving the demand for a rigorous account of being, subjectivity, and the absolute. The book is intended for readers interested in German idealism, post-Kantian philosophy, and the history of metaphysical systems. It treats Schelling’s project not merely as a historical episode but as a decisive transformation in the way philosophy conceives its own foundations. Cattin’s analysis is especially relevant for understanding the relationship between transcendental philosophy and metaphysical inquiry in early nineteenth-century German thought.
