ABSTRACT
Metametaphysics concerns foundational metaphysics. Questions of foundational metaphysics include: What is the subject matter of metaphysics? What are its aims? What is the methodology of metaphysics? Are metaphysical questions coherent? If so, are they substantive or trivial in nature? Some have claimed that the notion of grounding is useful in addressing such questions. In this chapter, we introduce some core debates about whether – and, if so, how – grounding should play a role in metametaphysics. We consider how grounding might be relevant to whether metaphysical questions are substantive, how to choose between metaphysical theories, and how to understand so-called “location problems.”
