Summa (Quaestiones ordinariae) art. LXIII-LXVII

Theologian and Scholastic philosopher Henry of Ghent (d. 1293) could arguably be considered the most significant thinker of the last quarter of the 13th century. His works remained influential well into the Renaissance.

The critical edition of articles 63-67 of Henry's Quaestiones ordinariae (Summa) is dedicated to the subjects discussed in his lectures held at the University of Paris, namely the common relations within the Trinity. These articles were composed around 1290. In them, Henry explores topics such as personal identity, equality and similitude, as well as their opposites: diversity, inequality and dissimilitude.

Articles 63-67 were distributed by the University of Paris in two successive exemplars divided into peciae. Manuscripts copied from each exemplar have survived. The text of the critical edition has been established based on the reconstructed texts of these two exemplars.

This volume will be of interest to those engaged in the study of theology, philosophy, book history and university history in the Middle Ages.
