Abstract

An appeal to ontological parsimony or economy plays an important, perhaps indispensable, role in evaluating metaphysical theories. This chapter focuses primarily on the first conception of grounding, grounding as metaphysical explanation. It briefly discusses the relation of ontological dependency and its connections with grounding as explanation. Debates about grounding are a recurring theme in the history of Western philosophy. Much of Aristotle's metaphysical method also presupposes the existence of a grounding relation. The chapter investigates both conceptual and ontological grounding and explores the relationship between grounding and truthmaking. The chapter considers various alternatives or competitors to grounding theory. It examines the connection between grounding, fundamentally, and Ockham's Razor and also relation between grounding and ontological dependence. The chapter shows how grounding is different from causal explanation and discusses connections between grounding and entailment.
