The forms of “composition” and the role of mediating concepts in Kant’s Opus postumum

The paper claims that in Kant’s Opus postumum the concept of coordination/composition is particularly suitable to assume a value that goes beyond the formal and normative aspect and encompasses also the material and descriptive domain. In this framework a crucial function is played by the Mittelbegriffe/Zwischenbegriffe, through which Kant seems to finally reach a promising way to explain how the understanding could concretely provide nature with a legislation, whose action can be seen as intrinsic to matter.
