Thesis 3>48
Latin
Praeter tria demonstrationis genera, quia, propter quid, et simpliciter, quae ponunt Aristoteles et commentator, datur quartum genus demonstrationis quae dici potest demonstratio conuertibilitatis, fortius omnibus praedictis.
English
Beyond the three kinds of demonstration that Aristotle and the Commentator posit — of the fact, of the reasoned fact, and unqualified demonstration — there exists a fourth kind, strongest of them all, which may be called demonstration by convertibility.
'commentator' = Averroes; the three named kinds correspond to the standard Posterior Analytics distinction (quia / propter quid / simpliciter); sense checked.
