  Buridan's metaphysics is thoroughly informed by his logic. He tries wherever possible to apply the Summulae's analytical techniques to solve problems in speculative philosophy. His approach is critical in the sense that he tends to view traditional problems in metaphysics as based on confusions of logic or language. For the same reason, his solutions are not original in the modern sense of being without precedent, although they have few equals in terms of their elegance and economy of expression. Where philosophical argumentation is concerned, Buridan is a master craftsman.
