Collationes Oxonienses are a collection of 26 questions concerning metaphysical and psychological topics discussed by John Duns Scotus and other bachelors in Oxford, in the spring of 1301. The critical edition presents a more complete and correct text compared to the Wadding edition and sheds new light on both the formation of Scotus's thought before the Paris period and the English Franciscan theology in the early 14th century.
