 Wolff’s treatment of metaphysics concludes with a consideration of natural theology defined as “the science of those things that are possible through God” (NT: I, §1, see Corr 1973). Yet, at the same time, natural theology also provides a bottom-up justification for metaphysics insofar as metaphysics is concerned with actual existing beings of a contingent, and so created, reality. Wolff indicates that natural theology has two principle aims: (1) to prove the existence of God and (2) to determine what pertains to the essence and attributes of God, and what follows from these.
