For Su?rez, the object of the metaphysics is being insofar as it is real
being (ens reale). In order to explain this, the author analyzes Su?rez?s
notions of formal and objective concept (conceptus formalis, conceptus
objectivus). Su?rez finds that the primary feature of the objective concept
of being is its unity; nevertheless that does not imply the univocal concept
of being because the objective concept of being is applied on its instances
on diverse ways. When considering what is being (ens), Su?rez makes the
difference between being taken as a noun and being taken as a participle. The
later one signifies everything actually existing; being as a noun signifies
everything which have the real essence (essentia realis), with actual
existence or without it. The real essence he defines as something that is not
repugnant to actual existence and which is not a figment of mind. The
objective concept of being is a result of precisive abstraction and encompass
all real essences, actual as well as non-actual. As such, for Su?rez, it is
the object of the metaphysics as a science.
