Tractatus Primus

In the Vatican manuscript Vat. lat. 817, which presents the same colophon, our treatise is introduced as follows: "Tractatus de activitate, unitate et augmentatione formarum activarum habendum contraria suscipiencium magis et minus." However, this title seems also to include the subject matter of the subsequent Tractatus secundus, De causa intrinseca intensionis et remissionis formarum accidentalium, in the colophon of which its current title is mentioned: "Explicit. . . Burleus de intensione et remissione formarum." (Burley's So-called Tractatus Primus, with an Edition of the Additional Quaestio "Utrum contradictio sit maxima oppositio" L.M. De Rijk
