 From this analysis Burley draws some rather important consequences about the nature and ontological status of relations and relatives: (1) the existence relations have is feebler than that of any other accident, as it depends upon the simultaneous existence of three different things: the substrate, the consequent term, and the foundation; (2) relations do not add any absolute perfection to the substances in which they occur; (3) relations can inhere in substances without any change in the latter, through a change in the consequent term of the relation (e.g., given two things, one white and the other black, if the black thing becomes white then because of the change, a new accident, a relation of similarity, will inhere in the other without any other change in it; (4) there are two main kinds of relatives: real (secundum esse) and linguistic (secundum dici). Linguistic relatives (such as ‘knowledge’ and ‘knowable’) are connected only by the mutual reference of the nouns signifying them. Real relatives are linked as well by a relation which inheres in one of them and entails a real reference to the other. Linguistic relatives in reality belong to the category of quality. Real relatives are aggregates compounded by a substance and a relation, so that they fall under the category of relation only indirectly (per reductionem) because of their accidental form. Finally (5), all true relatives are simultaneous by nature (simul natura), so Aristotle was wrong in denying that some pairs of relatives are mutually simultaneous, but one prior and the other posterior. In fact, the real cause of being a relative is the relation, which at the same time inheres in one thing and entails a reference to the other, thereby making both things relatives (EP, ch. de relatione, fols. 32va–b, 34ra, 37ra).
