Kantianism
Kantianism is the philosophy of Immanuel Kant, a German philosopher born in Königsberg, Prussia (now Kaliningrad, Russia). The term "Kantianism" or "Kantian" is sometimes also used to describe contemporary positions in philosophy of mind, epistemology, and ethics.
Metaphysics
Christian Wolff had theoretical philosophy divided into an ontology or "philosophia prima" as a general metaphysics, which arises as a preliminary to the distinction of the three "special metaphysics" on the soul, world and God: rational psychology, rational cosmology and rational theology. The three disciplines are called empirical and rational because they are independent of revelation. This scheme, which is the counterpart of religious tripartition in creature, creation, and Creator, is best known to philosophical students by Kant's treatment of it in the "Critique of Pure Reason". In the "Preface" of the 2nd edition of Kant's book, Wolff is defined "the greatest of all dogmatic philosophers."
