The Whole of Reason in Kant's Critical Philosophy

Kant often compares reason to an organized body, which suggests that reason should be understood as a whole from which all possible uses of the faculties of reason are derived. However, Kant does not elaborate his conception of the whole of reason. Nor does the secondary literature. This paper suggests that the wholeness of reason is the apodictic modality of reason, i.e., the necessary standard that determines what can systematically belong to reason, and thus works as the systematic condition for all possible uses of the faculties of reason. This necessary standard is the discipline of pure reason.
