Abstract

It will be recalled that Maritain regards his distinction between suppositio naturalis and suppositio accidentalis as a division within suppositio personalis, and as a division pertaining to the verb or to the copula (IV-28). If the subject has suppositio naturalis, then the copula expresses the relation of subject to predicate only in a possible existence.
