For those who are interested in learning more about the real Duns:
Hannah Arendt has a section in her book _The Life of the Mind_, in particular, Arendt's comments on Duns appear in part two of her one volume edition (they appear in the part on willing) and runs from pages 125-146.
One quote from Scotus is this one:
"in potestate voluntaris nostrae est habere nolle et velle, quae sunt contraria, respectu unius obiecti."
