Dunce \Dunce\, n. [From Joannes Duns Scotus, a schoolman called
   the Subtle Doctor, who died in 1308. Originally in the phrase
   "a Duns man". See Note below.]
   One backward in book learning; a child or other person dull
   or weak in intellect; a dullard; a dolt.
   [1913 Webster]

                                                  --Swift.
   [1913 Webster]

   Note: The schoolmen were often called, after their great
         leader Duns Scotus, Dunsmen or Duncemen. In the revival
         of learning they were violently opposed to classical
         studies; hence, the name of Dunce was applied with
         scorn and contempt to an opposer of learning, or to one
         slow at learning, a dullard.
         [1913 Webster]
