Petrus Thomae, Quaestiones de modis distinctionum q. 2 a. 1 (ed. forthcoming ca. 2030)
De tertio, scilicet quid sit realitas, dico duo:
Primum est quod realitas non dicit proprie rem, sed aliquid aliud ad rem pertinens. Hoc patet ex modo significandi, nam ab hoc quod ‘res’ derivatur ‘reale’, unde illud dicitur ‘reale’ quod est ad rem pertinens; sed ab hoc quod dicitur ‘reale’ derivatur ‘realitas’; realitas ergo proprie non dicit rem sed aliquid ad rem pertinens.
Secundum est descriptio quam pono de realitate, quae talis est: illud voco ‘realitatem’ quod est aliquid positivum in re ex natura rei, non contentum in alio | ut in pure passivo vel activo praecise vel sicut in superiori inferius sed actualiter et formaliter inexistens, ita quod ultimate abstractum nullum illorum a quo formaliter distinguitur includit impossibile est in actuali existentia ab illis separari per aliquam potentiam.
Concerning the third [section], namely, 'what is reality', I say two things"
First is that 'reality' does not mean properly 'thing', but something other pertaining to a thing. This is clear from the mode of understanding, for from this that 'real' is derived from 'thing', it is said that 'real' is that is pertaining ot a thing; but from 'real' is derived 'reality'; therefore, reality properly does not mean thing but something pertaining to a thing.
Second is the description which I posit of reality, which is thus: I call that [a] 'reality' which is something positive in a thing from the nature of a thing, not contained in anthoer as in the purely passive or purely active or as an inferior in a superior, but formally and actually existing-in, so that when it is ultimately abstracted it includes none of those from which it is formally distinguished [and] it is possible that it can be spearated from them in actual existence by some power.
Hmmm. well, it is based on two manuscripts. Good manuscripts, sure, but maybe something is missing. Commentary to come.
