Autonomy, creativity and limits of «pure reason»

In Opus Postumum, we can notice that Kant researches and defines a semantic structure of transcendental philosophy more complete, specific, articulate and systematic in connection with a “science of pure intellect” and a “science of pure subjectivity”: in this field of research, the critical analysis of the notion of “transcendental” becomes the original and authentic point of the Kantian philosophical transcendental system. “Transcendental Philosophy” − observes Kant in Opus Postumum − “is autonomy, that is, a reason that determinately delineates its synthetic principles, scope and limits in a complete system”. Transcendental philosophy is “autonomy” because human reason “determines itself” (bestimmt sich selbst) and “creates” its “synthetic principles”, its own “field” (Feld), “ambit” (Bereich), and its own “limits” (Grenzen), according to a “complete system”. From this perspective, in the last notes of Opus Postumum, Kant defines the notion of “limit” in connection with meta-cognitive rational processes and with the philosophical meaning of “possibility of possibility”: the final meaning of transcendental philosophy is related to a notion that Kant calls “philosophy of philosophy”.
