Abstract
The authors present a critical edition of the Quaestio de formalitatibus of John Duns Scotus. In the introduction to their edition, they examine the evidence of the manuscripts and the external and internal evidence to determine the authorship, place and date of the question. They conclude that the Quaestio was disputed by John Duns Scotus at Paris in the Franciscan studium sometime between 1305 and 1307. Chronologically, Scotus’ Quaestio, disputed at Paris, would seem to be his final, magisterial word on the subject of the formal distinction. Finally, the authors examine the transmission of the text in each of the manuscripts in order to establish a stemma codicum and the principles that govern their edition.
