This work intends to evaluate the origins and developments of the symbolic and heuristic function at stake in the term Ungeheuer [the monster or the monstrous] within Kant's philosophy, regarding the rising horizon of modern rationality. A reconfiguration of the Monster and Monstrous imagery seems to take place right at the moment when modern philosophy had to reflect upon its own identity and limits. Kant's thought, that occupies - de jure or de facto - a central place within this rupture could exemplarily, but not obviously, show the path of such transformation.
