Latin
In omni quaestione per demonstrationem scibili, oportet praecognoscere quid subiecti et passionis, non intelligendo per quid, quid nominis, ut intelligunt expositores, sed quid rei.
1486/1487 apparatus: 1486 per quid. quid nominis
English
In every question knowable through demonstration, one must first know the what of the subject and of the property demonstrated of it — understanding by 'what' not the meaning of the name, as the commentators take it, but the nature of the thing.
'quid nominis' versus 'quid rei' is the standard distinction between a nominal and a real definition.
