Introduction

Inquiry into ground is no exception. Questions of ground ask for explanations. But ground is supposed to be distinctive. What makes it distinctive is its involvement with a distinctively metaphysical kind of determinative explanation. Its being distinctively metaphysical is supposed to distinguish it from explanations from other domains, such as science, mathematics, and ethics. Its being determinative is supposed to distinguish it from other forms of explanation, such as causal or probabilistic explanations, in which what is explained needn’t constitutively depend on what explains it.
