Abstract

The article treats as significant the formal coincidence between Kant’s presentation of the science of metaphysics in the “Architectonic of Pure Reason” chapter of the first Critique and Alexander Baumgarten’s presentation of the same in the Metaphysica. From his comments on Baumgarten in the metaphysics lectures, the article shows that for Kant metaphysics in its traditional form lacked completeness and systematic order. Kant fits completeness into his architectonic plan of a scientific metaphysics by converting Baumgartian ontology into an “analytic of the understanding”; Kant achieves the systematicity by modeling a rational “idea of the form of the whole” after Baumgarten’s tree-like ordering of the special sciences of metaphysics. Thus, Kant realizes the completeness and systematicity in a theoretical presentation of the science of metaphysics that he finds lacking in Baumgarten precisely by borrowing from the latter his scheme for metaphysics.
