 It was G. W. Leibniz, however, who would exercise the most consequential influence on Wolff, both professionally (as seen above) and philosophically. Wolff is often described as a disciple or follower of Leibniz, a characterization for which there is some justification. So, central tenets of Wolff’s philosophical system closely resemble those advanced by Leibniz. The commitment to metaphysics, the extensive use of the principle of sufficient reason, and the (qualified) endorsement of the pre-established harmony are among many striking points of agreement. Indeed, Wolff appears not only to accept the principles and methods of analysis posed by Leibniz, but he also identifies opponents to his system, such as Descartes, Spinoza, and the Atomists, that Leibniz opposed in his own.
