A translation based on the Latin text of the Leonine edition.

The Quaestiones Disputatae de Veritate constitutes Aquinas's most extended treatment of any single topic. Volume I (questions 1-9) discusses the nature of truth and divine and angelic intellects. Volume II (questions 10-20) deals with truth and human intellect. Volume III (questions 21-29) investigates the operation of the will.
