Sie ist eine systematische und dialektische Auseinandesetzung mit Kants Architektonik der reinen Vernunft in der Kritik der reinen Vernunft. Damit zeigt Sie uns an, dass die Kritik der reinen Vernunft sich mit der Unterscheidung von Anschauung und Begriffen als eine Aufklärung einer praktischen Zweckmäßigkeit unserer Vernunft vorstellt.

In the Critique of Pure Reason, Kant states that ideas give us the rule for organizing experience and ideals serve as archetypes or standards against which one can measure copies. Further, he states that ideas and ideals can be practical. Understanding how precisely these concepts should function presents a challenging and understudied philosophical puzzle. I offer a reconstruction of how ideas and ideals might be practical in order to uphold, to my mind, a conceptually worthy distinction. A practical idea, I (...) argue, is best understood as a reference to the categorical imperative (and its various formulations), which guides conduct directly as a rule. A practical ideal, by contrast, I think is a substrate that serves two functions: one that (a) helps us gauge moral deficiencies and another that (b) reveals the potential for moral improvement. In response to well-grounded sceptical concerns, I argue that ideals are indirectly practical in that they ground the possibility to recognise moral states of affairs and be moral in the first place.
