Abstract This article demonstrates that the systematic progress in the elaboration of the Wissenschaftslehre during Fichte’s Jena period results from a continuous confrontation with Kant’s Critique of the Power of Judgment , which Fichte first read and reviewed in Leipzig. Fichte deems insufficient Kant’s proposed solution to bridge the “uncalculable” ( unübersehbare Kluft ) between theoretical and practical philosophy, a gap that jeopardizes philosophy as science. Only the theory of sollicitation ( Aufforderungstheorie ), first developed in the Foundations of Natural Right and later placed at the core of the New Presentation of the Wissenschaftslehre , allows for overcoming the unfinished nature of Kantian critique, refuting the accusation of solipsism raised by Jacobi, and safeguarding the unity of philosophy.
