Lambert of Lagny (Lambertus de Latiniaco) (fl. 1250) (not to be confused with the Dominican Lambert of Auxerre) is the author of one of the main logic textbooks of the terminist logic (Logica or Summa Lamberti). He belongs to the Parisian tradition as opposed to the Oxonian one. The Summa is posterior to and independent from the corresponding works of Peter of Spain, William of Sherwood, and Roger Bacon. Lambert’s semantic of terms is characterized by the acceptation of natural supposition (also in propositional context) and an original doctrine of appellation as a syntactic limitation of personal supposition.
