 There are many ways to make sense of these notion, but one natural approach is to take basicness as the foundation of ontological priority. That is, suppose that one begins with the notion of ontological priority, understood as an irreflexive and transitive relation between entities. Then ontological priority will induce a partial ordering over the domain of entities. Suppose one now adds the assumption that ontological priority requires foundations. These foundations will be those entities that are not posterior to any other entities. These are the basic, ungrounded  entities.[34]  Suppose one now adds a third assumption that there is a well-founded ontological dependency structure within the domain of concrete objects. Then one gets basic concrete objects. Being such an object is the property denoted by ‘\(B\)’.
