 It is first of all striking in Suárez's treatment that the class of entia rationis includes a seeming motley of cases, extending beyond non-existing objects of thought and reference (and so beyond non-existent final causes). In addition to final causes which are not, the student of being finds himself confronted with true-sounding appeals to phantasmagorical and mythical beasts and creatures of fiction of various sorts, even though their subjects have vacuous reference (“Pegasus is a winged horse”). More importantly, Suárez countenances a whole range of other non-beings among entia rationis, some of which are more pedestrian than creatures of fiction: negations, such as being not-human; privations, that is, lacks keyed to positive properties, such as blindness; and also (what he takes to be mere) logical abstractions, such as being a consequent or an antecedent; and taxonomical categories, which, in view of his general nominalism, he takes to be mere metaphysical abstractions, such as species and genus.
