terminist logic a school of logic originating in twelfth-century Europe and dominant in the universities until its demise in the humanistic reforms. Its chief goal was the elucidation of the logical form (the ‘exposition’) of propositions advanced in the context of Scholastic disputation. Its central theory concerned the properties of terms, especially supposition, and did the work of modern quantification theory. Important logicians in the school include Peter of Spain, William Sherwood, Walter Burley, William Heytesbury, and Paul of Venice.
