  This is obviously not enough to clarify the issue. The question remains: What is this foundation in reality which is the basis of the denomination? It cannot be a category itself, for categories for Suárez are concepts and the product of conception and abstraction (DM 39, 2, 23; 1861, 25:517a). And it cannot be a reality which is exactly represented by the distinction, for then the distinction would be real rather than conceptual. So what is it?
