Metaphysicae systema methodicum

The Metaphysicae systema methodicum by the Steinfurt professor Clemens Timpler (1563/4-1618) was, when it first appeared in 1604, the first textbook of metaphysics by a Protestant author, and was thus already a groundbreaking work of German academic philosophy, primarily in form and style but also in content. Firmly rooted in the tradition of Aristotle and the thomistic interpretation of his works, and making constant reference to Suarez’s recently-published Disputationes metaphysicae, Timpler developed a theory of astonishing originality, which was widely absorbed and intensively discussed in academic circles. It follows that the work would not have been unknown to Wolff, especially in view of Timpler’s designations of philosophy and metaphysics, modalities and freedom of will.
