  No encyclopedia article can do justice to the richness and variety of Buridan's logic; it was interest in logic that first revived the study of his work fifty years ago, and logic remains the one area in which Buridan can speak directly to modern philosophical audiences.  The main reason for this is that Buridan's project of developing a token-based semantics to ground his nominalist ontology is shared by many philosophers of language today; likewise, the method of his Treatise on Consequences has been rightly described by Hubert Hubien as “very modern: we have here what is without doubt the first attempt, albeit very imperfect, at an axiomatic exposition of logic on the basis of the propositional calculus.”[14] Nevertheless, this section will have the more modest aim of showing showing how Buridan practiced the dialectical art and influenced logic and semantics well into the sixteenth century.
