 That grounding figures in ordinary and philosophical thinking (and perhaps other domains as well) and that many grounding claims are fairly easy to evaluate (e.g., [Beijing exists] grounds [{Beijing} exists]) gives us defeasible reason to think that there is grounding (deRosset 2020).

In this section we set out three theoretical utility arguments for grounding that involve unity, explanation, and the direction of priority.
