 The first thing to notice about this list is its heterogeneity. Suárez is interested in a group of entities, broadly conceived, that end up in metaphysical discourse even though they do not exist. Note, too, that he does not say that such entities do not exist “strictly speaking” or “fully” or “really” or that they exist “in the mind or imagination only”. Instead he insists: they do not exist. Even so, in metaphysics and physics, we speak of genera and species; in logic, of antecedents and consequences; in causation and metaphysics more broadly, of privations; and in many walks of life, of non-existent entities, often enough innocently imputing causal profiles to them.
