 For example, a lot of referential NPs in natural language seem to stand for entities that many philosophers would not consider real, let alone fundamental. These include ontologically dependent, minor, and derivative objects such as holes, shadows, smiles, homes, problems, reasons, advantages, and mistakes, as well as construction-driven objects such as pluralities like “the stones in the garden”  (§3.1.1),  functional, variable, or intensional objects like “the increasing temperature” or “the book John needs to write”  (§3.1.1),  and intentional objects of the sort “the house John was dreaming about”  (§3.2).
