Abstract
The teachings of Francisco Suárez tend to have the queer quality of being at once transparent and unintelligible. An example of this is his theory of relations.
It is clear that, according to Suárez, a categorical relation is both really and modally identical to its foundation; on the other hand, however, the relative denomination does not apply to the foundation unless the terminus of the relation actually exists. One may ask, then: given that the foundation exists but the terminus does not, is the relation actually there, or not? Suárez does not seem to have a clear answer to this query.
